PRÉFACE<br />

Les médicaments sont généralement fabriqués à partir de substances que l’on trouve<br />

dans la nature en quantités quasi illimitées. Il n’en va pas de même pour la majorité des<br />

dérivés plasmatiques qu’il est impossible de fabriquer d’une autre manière que par<br />

fractionnement de plasma huma<strong>in</strong> dont la quantité est limitée à ce qui a pu être collecté<br />

auprès de donneurs.<br />

Comme les dérivés stables du plasma sont parfo<strong>is</strong> les seuls remèdes possibles à des<br />

maladies graves, on comprend que les autorités de santé s’enquièrent des précautions<br />

nécessaires pour garantir un approv<strong>is</strong>ionnement suff<strong>is</strong>ant du pays compte tenu de ce<br />

facteur limitant à la source.<br />

Interrogé à ce sujet, le <strong>KCE</strong> s’est rapidement rendu compte de la complexité du<br />

problème liée aussi bien aux conditions de collecte (volontariat et gratuité des dons)<br />

qu’aux problèmes d’équilibre f<strong>in</strong>ancier des différents acteurs et au peu de transparence<br />

à ce sujet. Nous avons cependant pu repartir d’audits déjà effectués.<br />

Nous remercions tous ceux qui nous ont aidés à y voir plus clair et en particulier les<br />

hôpitaux qui ont répondu massivement à notre enquête. Nous espérons avoir ouvert<br />

suff<strong>is</strong>amment de voies pour aider les décideurs à mettre en place des solutions à la fo<strong>is</strong><br />

sûres et coût-efficaces.<br />

CONTEXTE<br />

Résumé<br />

Le sang assure le transport d’éléments essentiels à la vie chez la personne, ma<strong>is</strong> il<br />

permet aussi de produire des dérivés qui <strong>in</strong>terviennent dans le traitement d’affections<br />

particulières chez d’autres personnes tels que les immunodéficiences et l’hémophilie.<br />

Ces dérivés résultent d’un processus de fractionnement du plasma. Le plasma est la<br />

partie liquide du sang de couleur transparente et jaune, composée à 90 % d’eau et pour<br />

le reste d’immunoglobul<strong>in</strong>es (à la consommation desquelles nous consacrons une partie<br />

de ce rapport), d’album<strong>in</strong>e, de facteurs de coagulation et de lipoproté<strong>in</strong>es. Ce plasma<br />

est obtenu soit par séparation des cellules sangu<strong>in</strong>es à la suite d’un don de sang total,<br />

soit par plasmaphérèse, processus qui cons<strong>is</strong>te à <strong>is</strong>oler le plasma du sang d’un donneur<br />

qui conserve a<strong>in</strong>si ses cellules sangu<strong>in</strong>es.<br />

En Belgique, la totalité du sang et du plasma est collectée par la Croix Rouge et<br />

quelques petits centres <strong>in</strong>dépendants. Les donneurs ne sont pas rémunérés<br />

conformément aux règles en vigueur dans l’Union Européenne. Le plasma collecté est<br />

vendu au Département Central de Fractionnement (DCF) a , une entrepr<strong>is</strong>e qui en<br />

effectue le fractionnement.<br />

La plupart des pays européens consomment une quantité plus grande de produits<br />

dérivés que ce que l’on peut extraire du sang et du plasma collectés auprès de leurs<br />

citoyens. Ils doivent donc s’approv<strong>is</strong>ionner pour le surplus auprès de fractionneurs qui<br />

achètent du plasma à l’étranger. Si ce plasma étranger venait un jour à manquer ou à<br />

n’être plus vendu qu’à des prix exorbitants, les pays importateurs pourraient se trouver<br />

en difficulté. Difficulté d’autant plus importante que les dérivés plasmatiques sont<br />

<strong>in</strong>d<strong>is</strong>pensables pour soigner certa<strong>in</strong>es maladies graves, D’où la question posée au <strong>KCE</strong><br />

de l’auto suff<strong>is</strong>ance de la Belgique en plasma et dérivés stables du plasma et des<br />

précautions à prendre pour réduire au maximum le r<strong>is</strong>que de pénurie.<br />

QUESTIONS DE RECHERCHE<br />

Pour éclairer cette problématique, nous avons tenté de répondre aux questions de<br />

recherche suivantes:<br />

A propos de l’offre:<br />

• Comment et en quelles quantités le plasma est il collecté en Belgique et dans<br />

d’autres pays? Quelles sont les évolutions observées? Quels subsides sont<br />

accordés pour assurer une collecte suff<strong>is</strong>ante?<br />

• Comment se passe la transformation du plasma recueilli en Belgique en<br />

produits dérivés stables? Quelles sont les quantités produites? Comment le<br />

processus est-il f<strong>in</strong>ancé?<br />

A propos de la demande:<br />

• Quelles sont les <strong>in</strong>dications médicales traitées avec des dérivés stables du<br />

plasma ? Quelles quantités sont nécessaires pour traiter ces <strong>in</strong>dications et<br />

quelles sont les quantités consommées en Belgique? Quelles tendances peuton<br />

prévoir dans les procha<strong>in</strong>es années?<br />

A propos de la sécurité de couverture de la demande :<br />

• Que faut-il entendre par sécurité de couverture d’une manière générale ?<br />

Quel niveau de couverture cherche-t-on à atte<strong>in</strong>dre en Belgique et dans<br />

d’autres pays?<br />

• Quelles sont les différentes démarches possibles pour atte<strong>in</strong>dre de façon<br />

optimale un niveau de couverture cho<strong>is</strong>i?<br />

a En néerlanda<strong>is</strong>: Centrale Afdel<strong>in</strong>g voor Fractioner<strong>in</strong>g (CAF). Au départ, il s’ag<strong>is</strong>sait d’un département de la<br />

Croix Rouge. Aujourd’hui, il s’agit d’une entrepr<strong>is</strong>e commerciale multi nationale, dans laquelle la Croix<br />

Rouge n’est plus qu’un actionnaire m<strong>in</strong>oritaire.

MÉTHODOLOGIE<br />

Nous avons adopté des méthodologies spécifiques à chacun des tro<strong>is</strong> thèmes traités<br />

dans ce rapport.<br />

En ce qui concerne les questions relatives à l’offre :<br />

Af<strong>in</strong> de déterm<strong>in</strong>er les quantités de plasma collectées, nous avons recueilli des données<br />

auprès des collecteurs belges. Des données fournies par la Croix-Rouge et le CAF-<br />

DCF ont été recoupées avec des données <strong>is</strong>sues d’un audit de ces deux <strong>in</strong>stitutions af<strong>in</strong><br />

de déterm<strong>in</strong>er les quantités de plasma vendues et achetées et leurs prix. Les données<br />

INAMI et une enquête auprès des hôpitaux nous ont perm<strong>is</strong> de déterm<strong>in</strong>er les quantités<br />

totales de produits dérivés vendues en Belgique, en d<strong>is</strong>t<strong>in</strong>guant celles fournies par le<br />

CAF – DCF et celles fournies par des firmes commerciales étrangères.<br />

Nous avons étudié l’évolution des quantités de dérivés stables produites et vendues par<br />

le CAF-DCF et les avons m<strong>is</strong>es en regard des quantités de plasma qu’il achète à la Croix<br />

Rouge. . Des documents <strong>in</strong>ternes de la Croix-Rouge a<strong>in</strong>si que l’audit dont elle a été<br />

l’objet nous ont perm<strong>is</strong> d’évaluer les coûts de ses activités et notamment de la<br />

plasmaphérèse qui constitue le mode de collecte de plasma dont la rentabilité était<br />

supposée <strong>in</strong>suff<strong>is</strong>ante. Les prix perçus par la CR ont été comparés aux prix<br />

<strong>in</strong>ternationaux af<strong>in</strong> d’évaluer le ga<strong>in</strong> potentiel pour la CR de vendre son plasma sur le<br />

marché <strong>in</strong>ternational.<br />

En ce qui concerne les questions relatives à la demande :<br />

La recherche s’est concentrée sur les immunoglobul<strong>in</strong>es (IG), qui représentent le dérivé<br />

plasmatique le plus déterm<strong>in</strong>ant de la demande. Les recommandations de bonne<br />

pratique en vigueur en Belgique et dans d’autres pays <strong>in</strong>dustrial<strong>is</strong>és ont été analysées.<br />

Une revue de la littérature, centrée sur les revues systématiques, s’est penchée sur<br />

l’efficacité des immunoglobul<strong>in</strong>es pour les <strong>in</strong>dications généralement repr<strong>is</strong>es dans les<br />

recommandations nationales en vue de pouvoir expliquer et prévoir les quantités<br />

consommées. Les caractér<strong>is</strong>tiques de consommation d’autres pays <strong>in</strong>dustrial<strong>is</strong>és ont été<br />

analysées pour déterm<strong>in</strong>er quelles <strong>in</strong>dications, pour lesquelles les IG ont montré une<br />

efficacité, représentaient la plus grande partie de la consommation en IG. En ce qui<br />

concerne la consommation en Belgique, tro<strong>is</strong> doma<strong>in</strong>es ont été exam<strong>in</strong>és:<br />

• Les données globales de consommation belge, basées sur les données de<br />

l’Inami (2004-2007) et sur une enquête auprès des pharmacies des hôpitaux<br />

belges (2008), ont perm<strong>is</strong> d’étudier les consommations « réelles » en terme<br />

de quantités globales prescrites et/ou remboursées en Belgique.<br />

• Les d<strong>is</strong>tributions des quantités prescrites par hôpital et par spécialité<br />

médicale, a<strong>in</strong>si que les pratiques médicales en cours, ont été étudiées à<br />

travers l’enquête auprès des pharmacies et une deuxième enquête auprès de<br />

services universitaires d’immuno-hématologie.<br />

• Une estimation théorique des quantités d’IG nécessaire pour traiter les 11<br />

<strong>in</strong>dications reconnues qui ont consommé 74% des IG dans les autres pays a<br />

été réal<strong>is</strong>ée sur base des données épidémiologiques belges ou des pays<br />

vo<strong>is</strong><strong>in</strong>s, a<strong>in</strong>si que des pratiques dans les centres belges ou <strong>in</strong>ternationaux.<br />

En ce qui concerne les questions relatives à la sécurité de couverture de la<br />

demande:<br />

Les d<strong>is</strong>positions pr<strong>is</strong>es en Belgique pour assurer son auto suff<strong>is</strong>ance en dérivés stables<br />

du plasma, ont été analysées. Une recherche dans la littérature gr<strong>is</strong>e et des contacts<br />

étrangers nous ont perm<strong>is</strong> de décrire les systèmes d’approv<strong>is</strong>ionnement, de la collecte à<br />

la consommation, dans plusieurs pays étrangers (France, Allemagne, Australie, Canada).


iv Plasma <strong>KCE</strong> Reports 120B<br />

RÉSULTATS<br />

En ce qui concerne le concept de sécurité de couverture<br />

La réglementation belge ne déf<strong>in</strong>it pas la proportion de produits sangu<strong>in</strong>s stables<br />

d’orig<strong>in</strong>e huma<strong>in</strong>e qui doit être produite en Belgique pour garantir son auto suff<strong>is</strong>ance.<br />

Un arrêté royal de 1998 préc<strong>is</strong>e seulement que pour garantir l’auto suff<strong>is</strong>ance et la<br />

qualité de l’approv<strong>is</strong>ionnement du pays en produits sangu<strong>in</strong>s stables d’orig<strong>in</strong>e huma<strong>in</strong>e,<br />

le prix du litre de plasma vendu par la Croix Rouge au CAF-DCF sera subsidié et qu’un<br />

Collège de rév<strong>is</strong>eurs transmettra chaque année au SPF le nombre de litres vendus en<br />

vue de calculer correctement le subside. Dans les faits, ce Collège observe qu’une<br />

quantité équivalente à 60% de la consommation plus un stock de quaranta<strong>in</strong>e de 180<br />

jours sont subsidiables. On en déduit implicitement que la Belgique est a<strong>in</strong>si auto<br />

suff<strong>is</strong>ante ma<strong>is</strong> nous n’avons trouvé aucune justification scientifique de cette proportion<br />

ni de la durée de la quaranta<strong>in</strong>e (période pendant laquelle le plasma doit être conservé<br />

avant d’être fractionné). Celle-ci est passée de 50 à 180 jours entre 1998 à 2006 sans<br />

que rien ne justifie cette hausse d’un po<strong>in</strong>t de vue de la sécurité médicale. Au contraire,<br />

de nouvelles techniques d’analyse biologique permettent de réduire la quaranta<strong>in</strong>e de<br />

façon drastique. Il semble donc que les concepts d’autosuff<strong>is</strong>ance et de quaranta<strong>in</strong>e<br />

n’ont jama<strong>is</strong> été vraiment réfléch<strong>is</strong> et déf<strong>in</strong><strong>is</strong> en Belgique.<br />

Au niveau <strong>in</strong>ternational, on ne retrouve pas non plus de justification officielle préc<strong>is</strong>e de<br />

ce qu’il serait plus exact d’appeler un ‘degré d’<strong>in</strong>dépendance’. En Australie,<br />

l’<strong>in</strong>dépendance complète semble être une f<strong>in</strong>alité implicite même si il est accepté d’avoir<br />

recours aux firmes étrangères pour des beso<strong>in</strong>s préc<strong>is</strong> et ponctuels. En France,<br />

l’autosuff<strong>is</strong>ance - déf<strong>in</strong>ie comme la part représentée par le chiffre d’affaires de<br />

l’opérateur national LFB dans le chiffre d’affaires total de la branche considérée sur le<br />

marché national - représente 75% pour les produits plasmatiques ma<strong>is</strong> avec des<br />

variations selon les produits considérés (par ex : 60% pour les IG). L’objectif fixé au LFB<br />

(Laboratoire França<strong>is</strong> de Fractionnement et de Biotechnologie) est d’atte<strong>in</strong>dre un niveau<br />

de production capable de couvrir potentiellement 100 % des beso<strong>in</strong>s des patients<br />

frança<strong>is</strong> en 2011. Toutefo<strong>is</strong>, si LFB est le seul opérateur à fractionner le plasma livré par<br />

l’Etabl<strong>is</strong>sement França<strong>is</strong> du Sang, il ne détient pas pour autant le monopole de vente des<br />

produits plasmatiques et reste en concurrence avec les autres entrepr<strong>is</strong>es présentes sur<br />

le marché frança<strong>is</strong>.<br />

En ce qui concerne la collecte du plasma<br />

Chaque pays développe des stratégies particulières pour collecter le plasma en quantités<br />

suff<strong>is</strong>antes. En France et en Allemagne, af<strong>in</strong> de favor<strong>is</strong>er le don de plasma, l’accent est<br />

m<strong>is</strong> sur les 18-25 ans et la collaboration avec les universités a<strong>in</strong>si que sur le suivi régulier<br />

des donneurs (très efficace) et la standard<strong>is</strong>ation des dons de manière à augmenter le<br />

volume par don. L’Etabl<strong>is</strong>sement França<strong>is</strong> de Sang s’est engagé contractuellement à<br />

augmenter ses livra<strong>is</strong>ons de plasma au LFB. En Allemagne, la logique commerciale<br />

prévaut (80% des dons) et les dons sont compensés f<strong>in</strong>ancièrement (jusqu’à 25 euros /<br />

limite fixée par la loi). En Australie, la collecte, l’approv<strong>is</strong>ionnement en produits dérivés<br />

et les contrats sont gérés par la National Blood Authority.<br />

En Belgique, sur base des données d<strong>is</strong>ponibles, la plasmaphérèse est une activité en<br />

perte de vitesse à la Croix-Rouge qui a même fermé certa<strong>in</strong>s centres de plasmaphérèse.<br />

Peut être la plasmaphérèse n’est elle pas jugée suff<strong>is</strong>amment rentable ? Cette rentabilité<br />

est toutefo<strong>is</strong> fonction, au mo<strong>in</strong>s partiellement, du mode d’affectation de coûts fixes à<br />

l’ensemble des activités.<br />

Chaque litre de plasma <strong>is</strong>su de plasmaphérèse et vendu dans le cadre de l’autosuff<strong>is</strong>ance<br />

donne droit à un subside de 24,79 euros versé à la CR, de façon à lui permettre de<br />

vendre ce plasma au CAF – DCF à un prix plus bas. La CR reçoit également un subside<br />

af<strong>in</strong> de couvrir le coût des tests NAT (Nucleic Acid Tests), effectués sur les<br />

prélèvements de sang, qui détectent la présence éventuelle de certa<strong>in</strong>s virus. Le<br />

paiement des consommables à la firme qui les commercial<strong>is</strong>e est peu transparent et<br />

permet de facturer des tests qui n’auraient pas été effectués réellement.


<strong>KCE</strong> Reports 120B Plasma v<br />

En ce qui concerne la transformation du plasma en produits dérivés stables :<br />

Le CAF – DCF assure le fractionnement de tout le plasma acheté sur le territoire en<br />

partenariat avec tro<strong>is</strong> entrepr<strong>is</strong>es (allemande, frança<strong>is</strong>e et hollanda<strong>is</strong>e). Les conventions<br />

de partenariat ne sont pas rendues publiques. Nos calculs montrent que le rapport<br />

entre les quantités de dérivés produites et les quantités de plasma fractionné par le<br />

CAF-DCF, est très variable d’une année à l’autre. Cette variabilité semble liée aux<br />

modifications de la demande <strong>in</strong>térieure et à la part de marché du CAF-DCF. Pour<br />

certa<strong>in</strong>s dérivés et certa<strong>in</strong>es années, le CAF-DCF d<strong>is</strong>pose de plus de plasma qu’il n’est<br />

nécessaire pour produire les quantités qu’il parvient à vendre.<br />

En ce qui concerne la consommation des produits dérivés stables :<br />

Les immunoglobul<strong>in</strong>es (IG) sont les dérivés qui nécessitent les plus grandes quantités de<br />

plasma pour répondre aux beso<strong>in</strong>s thérapeutiques. Les IG représentent aussi la majorité<br />

des dépenses en dérivés stables (33.4 millions € ou 62% du total des dérivés stables en<br />

2006), leur consommation augmente de manière cont<strong>in</strong>ue et le nombre d’<strong>in</strong>dications<br />

pour lesquelles les IG sont util<strong>is</strong>ées ne cesse d’augmenter. En Belgique, les IG sont<br />

actuellement remboursées pour 13 <strong>in</strong>dications. Une analyse de la prescription d’IG dans<br />

les hôpitaux belges a été réal<strong>is</strong>ée. Il en ressort que les prestataires de quatre spécialités<br />

ont prescrit 92% des IG en 2008 (médec<strong>in</strong>e <strong>in</strong>terne, neurologie, pneumologie et<br />

pédiatrie). On observe une grande hétérogénéité de la prescription entre les hôpitaux,<br />

en particulier en pneumologie. La prescription élevée d’IG en pneumologie (16% du<br />

total), prédom<strong>in</strong>ante dans quelques hôpitaux non universitaires, ne peut être reliée aux<br />

<strong>in</strong>dications remboursées en Belgique, à l’exception de certa<strong>in</strong>es déficiences immunitaires<br />

présentant des <strong>in</strong>fections respiratoires bactériennes répétées qui seraient traitées par<br />

des pneumologues; ce phénomène a également été rarement observé dans d’autres<br />

pays. En ce qui concerne l’évolution future de la demande, aucun modèle n’a pu être<br />

déf<strong>in</strong>i : certa<strong>in</strong>s facteurs pourraient augmenter la demande, comme des nouvelles<br />

<strong>in</strong>dications potentielles et l’augmentation de prévalence de certa<strong>in</strong>es maladies affectant<br />

surtout les personnes âgées ; d’autres facteurs pourraient la dim<strong>in</strong>uer, comme une<br />

limitation de la prescription aux <strong>in</strong>dications reconnues et le développement de thérapies<br />

alternatives pour les <strong>in</strong>dications actuelles des IG.<br />

Les <strong>in</strong>dications remboursées en Belgique ont été comparées à celles recommandées<br />

et/ou remboursées dans c<strong>in</strong>q autres pays (France, Royaume Uni (RU), Pays Bas, Canada<br />

et Australie), Table 1. Des recommandations belges sur l’util<strong>is</strong>ation des<br />

à usage compassionnel est <strong>in</strong>clue dans les données de tous les hôpitaux <strong>in</strong>terrogés.<br />

Celles-ci pourraient représenter une proportion significative des consommations<br />

d’après certa<strong>in</strong>s experts, et nous amèneraient donc à sous-estimer systématiquement<br />

les consommations en IG et donc la demande réelle.<br />

La deuxième limitation est liée à l’absence de vérification de l’affectation des coûts de<br />

structure de la Croix Rouge à l’activité de plasmaphérèse. Une autre forme de<br />

ventilation des coûts serait donc susceptible de réduire le déficit f<strong>in</strong>ancier, voire de le<br />

supprimer.<br />

La tro<strong>is</strong>ième limitation est liée à la variabilité du prix du plasma dans le temps et l’espace<br />

sur le marché <strong>in</strong>ternational. Cette variabilité empêche de tirer des conclusions claires<br />

sur les ga<strong>in</strong>s potentiels en cas de vente du plasma sur le marché <strong>in</strong>ternational

RECOMMANDATIONS<br />

En ce qui concerne la déf<strong>in</strong>ition de l’autosuff<strong>is</strong>ance<br />

• Le niveau implicite de couverture des beso<strong>in</strong>s adm<strong>is</strong> en Belgique entraîne une<br />

dépendance partielle à l’égard du marché <strong>in</strong>ternational. Cette dépendance<br />

devrait résulter d’un choix politique conscient basé sur une analyse de r<strong>is</strong>ques<br />

tenant compte des prix <strong>in</strong>ternationaux, de l’offre et de la demande<br />

<strong>in</strong>ternationales et des capacités de la CR et du CAF – DCF à répondre<br />

positivement à une hausse éventuelle de la demande <strong>in</strong>térieure.<br />

• Il est recommandé de revoir à la ba<strong>is</strong>se le nombre de jours requ<strong>is</strong> par la<br />

quaranta<strong>in</strong>e pour sécurité biologique.<br />

En ce qui concerne la collecte de plasma<br />

• Si l’autorité publique décidait d’augmenter le degré d’<strong>in</strong>dépendance de<br />

l’approv<strong>is</strong>ionnement en produits dérivés, il serait utile de s’<strong>in</strong>spirer des<br />

nombreuses politiques m<strong>is</strong>es au po<strong>in</strong>t à l’étranger et sur les réflexions<br />

ex<strong>is</strong>tant au niveau de l’UE. A<strong>in</strong>si, il est recommandé :<br />

o de mieux cibler le recrutement notamment en termes de tranches<br />

d’âge et de cibler les jeunes adultes (18-25) en priorité ;<br />

o d’assurer un suivi régulier des donneurs, et de façon plus générale une<br />

bonne gestion de celui-ci par l’organ<strong>is</strong>me de collecte ;<br />

o de procéder à des campagnes <strong>in</strong>tensives de sensibil<strong>is</strong>ation ;<br />

o sur le plan technique, de veiller à une véritable standard<strong>is</strong>ation et<br />

optim<strong>is</strong>ation des pratiques de collecte.<br />

• Dans une optique d’équité, l’ensemble des donneurs et en particulier les<br />

travailleurs, devraient être traités de la même manière, notamment en<br />

uniform<strong>is</strong>ant progressivement les avantages octroyés en cas de don de sang<br />

ou de plasma.<br />

• En ra<strong>is</strong>on d’un système peu transparent relatif à la facturation des tests NAT<br />

(Nucleic Acid Tests) et à leur subsidiation, il est recommandé de procéder à<br />

une déterm<strong>in</strong>ation des subsides qui tienne mieux compte des coûts réels<br />

supportés par la CR ou de vérifier la possibilité d’<strong>in</strong>clure le coût de ces tests<br />

dans le prix du sang.<br />

En ce qui concerne la consommation de dérivés stables du plasma<br />

• La variabilité des pratiques constatées - surtout dans des centres<br />

périphériques - <strong>in</strong>vite à recommander<br />

o la production de guidel<strong>in</strong>es au sujet de la prescription d’IG et de<br />

traitements alternatifs (une <strong>in</strong>itiative en ce sens est en cours au<br />

CSS/HGR) ;<br />

o de privilégier une prescription et un suivi par des spécial<strong>is</strong>tes et des<br />

centres de références pour le traitement par IG au long cours, comme<br />

cela est prévu pour l’usage du facteur VIII (convention pour les centres<br />

d’hémophilie).<br />

• Il est recommandé aussi d’améliorer le suivi de la prescription par<br />

l’établ<strong>is</strong>sement par exemple d’un reg<strong>is</strong>tre ou d’une base de données des<br />

patients traités par IG au long cours, et par la transm<strong>is</strong>sion de feedbacks aux<br />

prescripteurs avec l’util<strong>is</strong>ation de benchmark<strong>in</strong>g.


viii Plasma <strong>KCE</strong> Reports 120B<br />

En ce qui concerne la transparence des activités et des comptes des<br />

organ<strong>is</strong>mes subsidiés<br />

Une autorité subsidiante doit pouvoir contrôler l’util<strong>is</strong>ation des subsides qu’elle octroie<br />

directement ou <strong>in</strong>directement. Par conséquent:<br />

• Il est recommandé de lier la poursuite de la subsidiation du prix du plasma<br />

vendu au CAF-DCF à une communication transparente<br />

o des flux f<strong>in</strong>anciers et en volumes relatifs au plasma et aux<br />

produits dérivés qui transitent par le CAF-DCF et ses<br />

partenaires étrangers<br />

o Des termes du contrat qui lie le CAF-DCF à ses<br />

partenaires concernant l’util<strong>is</strong>ation directe ou <strong>in</strong>directe du<br />

plasma collecté en Belgique<br />

de manière à pouvoir vérifier l’utilité des subsides dans le cadre d’une<br />

politique d’auto suff<strong>is</strong>ance clairement déf<strong>in</strong>ie;<br />

• Il est également recommandé de mener un audit approfondi des comptes de<br />

la CR af<strong>in</strong> de déterm<strong>in</strong>er avec préc<strong>is</strong>ion la structure des coûts de l’activité de<br />

plasmaphérèse et d’en déduire le subside m<strong>in</strong>imal éventuellement nécessaire<br />

pour assurer que cette activité soit f<strong>in</strong>ancièrement en équilibre, et a<strong>in</strong>si<br />

soutenir la collecte du niveau souhaité de plasma source.

1 INTRODUCTION<br />

1.1 CONTEXT<br />

Blood transports elements that are essential to life <strong>in</strong> <strong>in</strong>dividuals, but it can also be used<br />

to produce derivatives that are used <strong>in</strong> the treatment of specific d<strong>is</strong>orders <strong>in</strong> others<br />

such as immunodeficiency and haemophilia. <strong>The</strong>se derivates are produced by a process<br />

called plasma fractionation. Plasma <strong>is</strong> the transparent yellow<strong>is</strong>h liquid part of the blood,<br />

composed of 90% water and the rest of immunoglobul<strong>in</strong>s (a part of th<strong>is</strong> <strong>report</strong> <strong>is</strong><br />

devoted to their consumption), album<strong>in</strong>, coagulation factors and lipoprote<strong>in</strong>s. Th<strong>is</strong><br />

plasma <strong>is</strong> obta<strong>in</strong>ed either by separation of the red blod cells follow<strong>in</strong>g a whole blood<br />

donation, or by plasmapheres<strong>is</strong>, a process used to <strong>is</strong>olate the plasma from the blood of<br />

a donor, which reta<strong>in</strong>s the red blood cells.<br />

In Belgium, all of the blood and plasma <strong>is</strong> collected by the Red Cross and a few<br />

<strong>in</strong>dependent centres. <strong>The</strong> donors are not paid, <strong>in</strong> accordance <strong>with</strong> the rules <strong>in</strong> force <strong>in</strong><br />

the European Union. <strong>The</strong> collected plasma <strong>is</strong> sold to a company <strong>in</strong> Belgium, which<br />

performs the fractionation.<br />

<strong>The</strong> majority of European countries consume a greater quantity of derivatives than can<br />

be extracted from the blood and plasma collected from their citizens. <strong>The</strong>y must<br />

therefore obta<strong>in</strong> other supplies from fractionation companies that buy plasma abroad. If<br />

th<strong>is</strong> foreign plasma should one day be <strong>in</strong> short supply or only be <strong>available</strong> at exorbitant<br />

prices, import<strong>in</strong>g countries may f<strong>in</strong>d themselves <strong>in</strong> difficulty. Th<strong>is</strong> difficulty <strong>is</strong><br />

exacerbated by the fact that plasma derivatives are vital for the treatment certa<strong>in</strong><br />

serious illnesses, hence the question posed to the <strong>KCE</strong> of self-sufficiency for Belgium <strong>in</strong><br />

plasma and plasma derivatives and the precautions to be taken to reduce as far as<br />

possible the r<strong>is</strong>k of a shortfall <strong>in</strong> supplies.<br />

1.2 RESEARCH QUESTIONS<br />

To clarify the <strong>is</strong>sue, we <strong>in</strong>tend to answer the follow<strong>in</strong>g questions:<br />

Concern<strong>in</strong>g supply:<br />

• How and <strong>in</strong> what quantities <strong>is</strong> plasma collected <strong>in</strong> Belgium and <strong>in</strong> other<br />

countries? What trends have been observed? What subsidies are<br />

provided to ensure that enough <strong>is</strong> collected?<br />

• How are derivative products manufactured from the plasma collected <strong>in</strong><br />

Belgium? What are the quantities produced? How <strong>is</strong> it f<strong>in</strong>anced?<br />

Concern<strong>in</strong>g demand:<br />

• Which medical <strong>in</strong>dications are treated <strong>with</strong> plasma stable derivatives ?<br />

Which amounts are required to treat these conditions and which<br />

amounts are consumed <strong>in</strong> Belgium? Which trends can we expect over<br />

the com<strong>in</strong>g years?<br />

Concern<strong>in</strong>g security of coverage of demand:<br />

• What it meant by security of coverage <strong>in</strong> general? What level of coverage<br />

do we seek to achieve <strong>in</strong> Belgium and <strong>in</strong> other countries?<br />

• What different approaches could be used to achieve optimally the desired<br />

level of coverage?

2 SUPPLY OF PLASMA DERIVATIVES<br />

2.1 COLLECTION OF PLASMA<br />

2.1.1 Legal and ethical framework<br />

Plasma donation and collection processes have to abide by specific rules, both from a<br />

sanitary and ethical po<strong>in</strong>t of view.<br />

As a human product, collection and use of plasma are subject to specific rules, <strong>with</strong> a<br />

view to protect<strong>in</strong>g patient safety, and also donor’s security. Moreover specificity of<br />

plasma <strong>is</strong> that they stem from human donation. In the current state of science, artificial<br />

plasma as such cannot be produced, and the supply of plasma cannot be guaranteed.<br />

<strong>The</strong>refore donation <strong>is</strong> of paramount importance.<br />

However, one must clearly d<strong>is</strong>t<strong>in</strong>gu<strong>is</strong>h one the one hand donation and collection that<br />

rema<strong>in</strong> <strong>in</strong> the hands of each national system and on the other hand the global market of<br />

plasma-derived products, that <strong>is</strong> subject to free competition between private firms.<br />

For all these reasons, a very strict and specific legal and ethical framework has been<br />

def<strong>in</strong>ed. Given the high level of economic <strong>in</strong>tegration between EU economies <strong>in</strong> the field<br />

of plasma-derived products, but also the common expectations of EU citizens, these<br />

rules have been set out on the EU level.<br />

2.1.1.1 European and <strong>in</strong>ternational context: which impact?<br />

EU regulatory framework on blood and blood products<br />

More prec<strong>is</strong>ely, the key regulatory texts of the EU legal framework cover the follow<strong>in</strong>g<br />

subjects:<br />

QUALITY ISSUES: 2 DIRECTIVES<br />

Directive 2002/98/EC (27 January 2003) 1 sett<strong>in</strong>g standards of quality and safety for<br />

the collection, test<strong>in</strong>g, process<strong>in</strong>g, storage, and d<strong>is</strong>tribution of human blood and blood<br />

components and amend<strong>in</strong>g directive 2001/83/EC. Th<strong>is</strong> directive focuses on the follow<strong>in</strong>g<br />

aspects: prov<strong>is</strong>ions for establ<strong>is</strong>hments, quality management, haemovigilance, quality and<br />

safety of blood (and blood components), <strong>report</strong><strong>in</strong>g requirements, etc…<br />

Directive 2004/33/ EC (22 March 2004) 2 implement<strong>in</strong>g directive 2002/98 as<br />

regards certa<strong>in</strong> technical requirements for blood and blood components. Th<strong>is</strong> directive<br />

<strong>is</strong> also of paramount importance, as the appendixes l<strong>is</strong>t the key requirements for the<br />

practical organization of blood donation: def<strong>in</strong>ition of terms and concepts, eligibility<br />

criteria for donors, storage and d<strong>is</strong>tribution conditions, quality/safety requirements.<br />

TRACEABILITY REQUIREMENTS: 1 DIRECTIVE<br />

Directive 2005/61/ EC (30 September 2005) 3 implement<strong>in</strong>g directive 2002/98 of<br />

the European Parliament and of the Council as regards traceability requirements and<br />

notification of serious adverse events reactions and events.<br />

QUALITY SYSTEM FOR BLOOD ESTABLISHMENTS: 1 DIRECTIVE<br />

Directive 2005/62/ EC (30 September 2005) 4 implement<strong>in</strong>g directive 2002/98 of<br />

the European Parliament and of the Council as regards Community standards and<br />

specifications relat<strong>in</strong>g to a quality system for blood establ<strong>is</strong>hments.<br />

However, the <strong>is</strong>sue of self-sufficiency as such has not been addressed by the EU<br />

regulation so far and has been left to each country’s d<strong>is</strong>cretion. Besides, as far as plasma<br />

products are concerned, some further explanation <strong>is</strong> required, <strong>in</strong> terms of legal status.<br />

Indeed, it <strong>is</strong> a thorny and complex problem both from an <strong>in</strong>tellectual and political po<strong>in</strong>t<br />

of view.


<strong>KCE</strong> Reports 120 Plasma 7<br />

Focus: status of plasma products <strong>with</strong> regard to the EU leg<strong>is</strong>lation<br />

Legal status of plasma-derived products rema<strong>in</strong>s a sensitive and delicate subject both<br />

from a legal and political po<strong>in</strong>t of view.<br />

<strong>The</strong> ma<strong>in</strong> <strong>is</strong>sue <strong>is</strong> to have a clear view on the legal nature of blood products, to be<br />

specific of plasma-derived products. Whereas these products are blood products or<br />

drugs might have far-reach<strong>in</strong>g consequences, especially <strong>in</strong> terms of freedom of<br />

circulation.<br />

Until now, no case law of the European Court of Justice has been identified on the legal<br />

status of blood or plasma products, as such.<br />

<strong>The</strong> problem has really not been solved and the arguments l<strong>is</strong>ted below must be<br />

considered <strong>with</strong> great care, and might be challenged by the ECJ <strong>in</strong> the future. To some<br />

extent, one can rely on a body of legal evidence, consider<strong>in</strong>g the spirit of the ex<strong>is</strong>t<strong>in</strong>g<br />

EU leg<strong>is</strong>lation on blood and blood products.<br />

Directive 2004/33/ EC (22 March 2004) mentioned above sets out <strong>in</strong> Annex I a<br />

long and prec<strong>is</strong>e l<strong>is</strong>t of what <strong>is</strong> considered as “blood” and “blood components”, to<br />

which the directive’s requirements are applicable.<br />

Directive 2001/83 /EC (6 November 2001) on medic<strong>in</strong>al products: it <strong>is</strong> clearly<br />

stated <strong>in</strong> th<strong>is</strong> directive that “medic<strong>in</strong>al products derived from human blood or human<br />

plasma” can resort to “album<strong>in</strong>, coagulat<strong>in</strong>g factors and immunoglobul<strong>in</strong> of human<br />

orig<strong>in</strong>”. We can easily draw the conclusion that all these products are considered as<br />

medic<strong>in</strong>al products.<br />

One can easily <strong>in</strong>fer from the directives mentioned above that products that are l<strong>is</strong>ted<br />

<strong>in</strong> the Directive are blood products (and not pharmaceutical drugs) and are a matter for<br />

the EU Blood and Blood products leg<strong>is</strong>lation. Likew<strong>is</strong>e, one can also <strong>in</strong>fer that products<br />

resort<strong>in</strong>g to human plasma (alone or comb<strong>in</strong>ed <strong>with</strong> other substances) that are sold by<br />

pharmaceutical firms, after completion of the fractionation process, must be considered<br />

as drugs.<br />

Nonetheless, plasma fractionation <strong>is</strong> an extremely long and complex process, and the<br />

range of plasma-derived products <strong>is</strong> very wide. <strong>The</strong>refore, a “grey zone” can be<br />

identified between blood and blood-components and plasma-derived drugs as described<br />

<strong>in</strong> the previous paragraph. <strong>The</strong> ma<strong>in</strong> <strong>is</strong>sue <strong>is</strong> to def<strong>in</strong>e accurate criteria to d<strong>is</strong>t<strong>in</strong>gu<strong>is</strong>h<br />

“blood components” and “pharmaceutical drugs” and to draw a border between both<br />

concepts. Th<strong>is</strong> <strong>is</strong> not an easy task, from a purely conceptual and legal po<strong>in</strong>t of view.<br />

For lack of regulatory def<strong>in</strong>ition (or official case law of the European Court of Justice),<br />

several EU Directives on health-related subjects can provide us <strong>with</strong> <strong>in</strong>terest<strong>in</strong>g clues on<br />

that po<strong>in</strong>t, <strong>in</strong> several texts especially EU Regulation (EC) 1394/2007 on advanced<br />

therapies (13 November 2007) on advanced therapy medic<strong>in</strong>al products (amend<strong>in</strong>g<br />

Directive 2001/83 and Regulation 726/2004). <strong>The</strong> latter regulation deals <strong>with</strong> advanced<br />

therapies resort<strong>in</strong>g to cells or t<strong>is</strong>sues. One of the key <strong>is</strong>sues of th<strong>is</strong> regulation <strong>is</strong> to<br />

identify products that can be considered as “medic<strong>in</strong>al products”. To th<strong>is</strong> end, the<br />

regulation (Art.2 Def<strong>in</strong>itions) resorts to the concept of “eng<strong>in</strong>eered products” (as<br />

opposed to non eng<strong>in</strong>eered products).<br />

To be more specific only cells or t<strong>is</strong>sues that undergo “substantial manipulations” can be<br />

considered as “advance therapy medic<strong>in</strong>al products”. Given that cl<strong>in</strong>ical practice or<br />

scientific literature do not give a clear-cut def<strong>in</strong>ition of th<strong>is</strong> concept, th<strong>is</strong> regulation sets<br />

out a l<strong>is</strong>t of practices (Annex I) that are not considered as “substantial manipulations”.<br />

In practical terms, such practices as centrifugation, sterilization, filter<strong>in</strong>g, and freez<strong>in</strong>g<br />

can be considered as “substantial manipulations” as such.<br />

<strong>The</strong>n, a second criterion <strong>is</strong> used <strong>in</strong> the Directive, to be specific the volume of<br />

production: the scope of the regulation clearly refers to the rout<strong>in</strong>e <strong>in</strong>dustrial<br />

production of medic<strong>in</strong>al products (<strong>with</strong> a view to putt<strong>in</strong>g them on the market), and not<br />

to custom-made treatments. Thus, a product that <strong>is</strong> used <strong>with</strong><strong>in</strong> a hospital <strong>in</strong> compliance<br />

<strong>with</strong> a medical prescription and delivered to a patient <strong>is</strong> clearly excluded from the scope<br />

of the regulation, s<strong>in</strong>ce it <strong>is</strong> not considered as a medic<strong>in</strong>al product.


8 Plasma <strong>KCE</strong> Reports 120<br />

In the light of these criteria, only products that comply <strong>with</strong> these two criteria should<br />

be considered as “medic<strong>in</strong>al products”. However, one must rema<strong>in</strong> cautious on that<br />

po<strong>in</strong>t, and keep th<strong>is</strong> legal <strong>is</strong>sue under scrut<strong>in</strong>y.<br />

Apart from purely regulatory subjects, the EU level also plays a strategic role <strong>in</strong> the<br />

promotion of voluntary unpaid donation, <strong>in</strong> order to identify avenues worth explor<strong>in</strong>g<br />

to improve EU countries’ self-sufficiency, <strong>with</strong><strong>in</strong> the ethical and regulatory framework<br />

described above. Th<strong>is</strong> EU will play an important role over the next years.<br />

EU policy and ongo<strong>in</strong>g projects on promotion of voluntary unpaid donation<br />

SURVEY OF THE EU COMMISSION (DG SANCO) ON PROMOTION OF UNPAID<br />

DONATION<br />

One of the key <strong>is</strong>sues for political dec<strong>is</strong>ion-makers, but also for practical organization of<br />

blood and plasma donation <strong>is</strong> the lucrative or unpaid nature of donation. Th<strong>is</strong> takes us<br />

back to ethical notions, and to a philosophical and political debate.<br />

Some countries like the United States clearly opted for remuneration of donation,<br />

whereas others - like Canada and EU countries - opted for non remuneration of<br />

donation. <strong>The</strong> EU level formally recorded that donation <strong>is</strong> unpaid. With<strong>in</strong> th<strong>is</strong> ethical<br />

framework, the EU level organized an <strong>in</strong>-depth enquiry to learn more on ex<strong>is</strong>t<strong>in</strong>g<br />

practices on unpaid donation across Member States.<br />

A Europe-wide survey has been launched by the EU-Comm<strong>is</strong>sion (DG Sanco) 5 a few<br />

years ago on that subject, and a <strong>summary</strong> <strong>report</strong> has been <strong>is</strong>sued on 17 th May 2006.<br />

Across Member States, practices can vary on two po<strong>in</strong>ts: Interpretation of the pr<strong>in</strong>ciple<br />

of “unpaid donation” and Promotion of donation itself.<br />

Interpretation of the pr<strong>in</strong>ciple of “unpaid donation”: from a political and ethical po<strong>in</strong>t of<br />

view, the pr<strong>in</strong>ciple of “unpaid donation” <strong>is</strong> the cornerstone of the donation systems, all<br />

over the EU. However, th<strong>is</strong> pr<strong>in</strong>ciple does not exclude “f<strong>in</strong>ancial compensation” for<br />

donors <strong>in</strong> some countries (or <strong>in</strong> specific <strong>in</strong>stitutions <strong>with</strong><strong>in</strong> these countries, depend<strong>in</strong>g<br />

on their own political options). <strong>The</strong> amount of th<strong>is</strong> f<strong>in</strong>ancial compensation <strong>is</strong> kept below<br />

a specific threshold set out by leg<strong>is</strong>lation, and the nature of expenses covered (and not<br />

covered) by th<strong>is</strong> compensation (travel expenses, car park, etc..) <strong>is</strong> generally set out very<br />

prec<strong>is</strong>ely by the country’s leg<strong>is</strong>lation.<br />

Germany <strong>is</strong> a traditional example on that po<strong>in</strong>t: as expla<strong>in</strong>ed further <strong>in</strong> the <strong>report</strong>, many<br />

German <strong>in</strong>stitutions <strong>in</strong>volved <strong>in</strong> donation - especially private <strong>in</strong>stitutions <strong>in</strong>volved <strong>in</strong><br />

plasma donation- apply f<strong>in</strong>ancial compensation as an <strong>in</strong>centive for donors. <strong>The</strong> amount<br />

of th<strong>is</strong> compensation can reach € 25 for each donation (maximum amount set out by<br />

the German leg<strong>is</strong>lation).<br />

As a result of th<strong>is</strong> compensation mechan<strong>is</strong>m and depend<strong>in</strong>g on the frequency of<br />

donation, regular donors are apt to receive a yearly amount of money, that <strong>is</strong> far from<br />

be<strong>in</strong>g nom<strong>in</strong>al (around 1000 €).<br />

Promotion of donation itself: a very wide range of media and <strong>in</strong>stitutions have been<br />

used or mobil<strong>is</strong>ed to support donation:<br />

• Information campaigns resort<strong>in</strong>g to traditional media (leaflets, posters,<br />

press) or modern media, especially <strong>in</strong>ternet.<br />

• Special events on donation: World blood donor day or other events<br />

focus<strong>in</strong>g on donation.<br />

• Specific Student and secondary schools’ pupils awareness: <strong>in</strong> many<br />

Member States, ra<strong>is</strong><strong>in</strong>g awareness of th<strong>is</strong> age group <strong>is</strong> of paramount for<br />

further recruitment of donors.<br />

FURTHER DEVELOPMENTS ON THAT SUBJECT ON THE EU LEVEL: SHARING BEST<br />

PRACTICES BETWEEN MEMBER STATES<br />

In the light of these f<strong>in</strong>d<strong>in</strong>gs, the EU Comm<strong>is</strong>sion decided to carry out a new study on<br />

best practices for promotion of voluntary unpaid, <strong>in</strong> order to share best practices<br />

between Member States. <strong>The</strong> f<strong>in</strong>d<strong>in</strong>gs of th<strong>is</strong> new study should be <strong>available</strong> <strong>in</strong> early<br />

2010.


<strong>KCE</strong> Reports 120 Plasma 9<br />

Two technical European projects have been designed and implemented on donation:<br />

“DOMAINE” / Donor Management <strong>in</strong> Europe focus<strong>in</strong>g on recruitment, retention and<br />

long-term management of donors and “Optimal Blood Use” focus<strong>in</strong>g on the cl<strong>in</strong>ical and<br />

technical use of blood components. <strong>The</strong>se projects are all the more important as they<br />

will be completed <strong>in</strong> 2010 and should deliver helpful <strong>in</strong>formation on best practices on<br />

these subjects.<br />

“DOMAINE”: Donor Management <strong>in</strong> Europe: http://www.doma<strong>in</strong>eeurope.eu/Home/tabid/36/Default.aspx<br />

DOMAINE (Donor Management IN Europe) <strong>is</strong> a European project, <strong>in</strong> which blood<br />

establ<strong>is</strong>hments from 14 European member states and one patient-driven organ<strong>is</strong>ation<br />

jo<strong>in</strong> their forces on donor management. DOMAINE aims to create a safe and sufficient<br />

blood supply, by compar<strong>in</strong>g and recommend<strong>in</strong>g good donor management practice. Even<br />

if 14 Member States play a lead<strong>in</strong>g role as partners countries, surveys obviously covers<br />

European practices, ie all EU countries, and a small number of European non-EU<br />

countries (as a whole 34 countries).<br />

Th<strong>is</strong> project does not deal specifically <strong>with</strong> plasma donation. However, pr<strong>in</strong>ciples of<br />

donor management are apt to be applied to plasma donation as well.<br />

<strong>The</strong> whole range of donor management <strong>is</strong>sues will be addressed: donor recruitment<br />

strategies, donor retention strategies, deferral procedures and blood bank policy<br />

regard<strong>in</strong>g patients requir<strong>in</strong>g long-term transfusion.<br />

Key po<strong>in</strong>ts<br />

• <strong>The</strong> EU concept of unpaid donation, opposable to all EU countries, does not<br />

exclude f<strong>in</strong>ancial compensation. Interpretation of th<strong>is</strong> latter concept may<br />

vary across Member States. Exchange of best practices on unpaid donation<br />

will also be <strong>available</strong> over the next years.<br />

• Noticeable d<strong>is</strong>crepancies have been identified <strong>in</strong> donor’s management but<br />

also <strong>in</strong> the use of blood and plasma across EU countries. <strong>The</strong> EU level’s<br />

objective <strong>is</strong> to support harmonization of practices. As a result, a<br />

contribution <strong>is</strong> expected from 2010 onwards: Manual on donor management,<br />

Manual on the rational use of blood and plasma.<br />

2.1.1.2 Contribution to the ethical debate on donation<br />

Over the last decades, blood and plasma donation has ra<strong>is</strong>ed very specific ethical<br />

questions for the follow<strong>in</strong>g reasons:<br />

• Blood and plasma products are human products and not <strong>in</strong>dustryproduced<br />

drugs.<br />

• Donation <strong>is</strong> based on a voluntary and <strong>in</strong>dividual act (at least <strong>in</strong> western<br />

countries).<br />

• Donation does not meet supply/demand rules <strong>in</strong> the traditional economic<br />

sense.<br />

• Specific ethical problems may appear both on the donor’s and user’s side.<br />

• Ethical frameworks of donation systems have a major impact on selfsufficiency,<br />

as shown <strong>in</strong>ter allia by the Canadian experience (see below).<br />

Ma<strong>in</strong> ethical dimensions of blood donation<br />

In Europe, many reflections have been conducted for several decades on blood and<br />

plasma donation and over the last years the University of Vienna <strong>in</strong> Austria<br />

(http://www.medicalethics.at/) , has conducted an <strong>in</strong>-depth reflection on that subject.


10 Plasma <strong>KCE</strong> Reports 120<br />

THE REFLECTION ON ETHICAL DIMENSION OF STEPS:<br />

1. Ma<strong>in</strong> specificities of blood and plasma donation<br />

<strong>The</strong> ma<strong>in</strong> traits of blood and plasma donation have been identified by Richard Titmuss<br />

and officially set out <strong>in</strong> the follow<strong>in</strong>g article “Why give to strangers?“ Lancet 16 January<br />

1971 6 and h<strong>is</strong> book titled “<strong>The</strong> gift relationship: from human blood to social policy” (last<br />

edition 1997) 7 . <strong>The</strong> most specific traits of th<strong>is</strong> “Gift relationship” <strong>is</strong> its potentially onesided<br />

and not reward<strong>in</strong>g dimension of th<strong>is</strong> donation:<br />

• Physically uncomfortable<br />

• Anonymous and not reward<strong>in</strong>g (<strong>in</strong>dividually)<br />

• Potentially one-sided dimension (donor can be excluded from a future<br />

donation)<br />

• Absence of donation does not <strong>in</strong>volve any sanction<br />

• <strong>The</strong> use of donated blood depends on a large number of people<br />

• For the donor, donation <strong>is</strong> no great or def<strong>in</strong>itive loss whereas for the<br />

recipient, it can be a matter of life and death<br />

For all the reasons mentioned above blood and plasma donation can be considered as a<br />

very specific k<strong>in</strong>d of gift, not to be compared <strong>with</strong> other k<strong>in</strong>d of donations or “gift<br />

relationships”. Moreover blood and plasma donation as such entail specific symbolic<br />

dimensions (Myth of Blood). Further details: see Appendix<br />

2. Ma<strong>in</strong> learn<strong>in</strong>gs<br />

It <strong>is</strong> important to underl<strong>in</strong>e that h<strong>in</strong>der<strong>in</strong>g factors for donation must be considered <strong>in</strong><br />

close connection <strong>with</strong> the <strong>in</strong>dividuals’ past attitude towards donation (ie ever donors or<br />

non donors).<br />

<strong>The</strong> collection regimes may have an impact on donors’ motivation and donators’<br />

profiles. In practice, it often <strong>in</strong>volves a split between two donors profile. <strong>The</strong>refore, it<br />

<strong>is</strong> of key importance to bear <strong>in</strong> m<strong>in</strong>d that such subjects as f<strong>in</strong>ancial compensation cannot<br />

be considered separately from other subjects. <strong>in</strong> countries were compensation <strong>is</strong><br />

applied, plasma donors are generally younger, more educated, and less <strong>in</strong>volved <strong>in</strong><br />

professional life than whole blood donors. Conversely, <strong>in</strong> countries where no f<strong>in</strong>ancial<br />

compensation <strong>is</strong> provided any clear d<strong>is</strong>t<strong>in</strong>ction, <strong>in</strong> terms of donors’ profile, has been<br />

identified so far.<br />

MAXIMIZATION OF THE USE OF THE DONATED BLOOD AS AN ETHICAL IMPERATIVE<br />

Consensual prerequ<strong>is</strong>ites can be easily set out as follows, basically for purely practical<br />

reasons:<br />

- Plasma <strong>is</strong> a scarce resource (plasma as raw material <strong>is</strong> not <strong>in</strong>dustry-produced)<br />

- Plasma fractionation rema<strong>in</strong>s a complex and costly process. <strong>The</strong>refore it <strong>in</strong>volves very<br />

specific imperatives for stakeholders, more prec<strong>is</strong>ely:<br />

• Facilitat<strong>in</strong>g plasma collection (br<strong>in</strong>g<strong>in</strong>g down actual or potential barriers to<br />

donation)<br />

• Handl<strong>in</strong>g plasma and plasma-derived products cautiously<br />

• D<strong>is</strong>tribut<strong>in</strong>g burdens and benefits fairly to all participants of the collection<br />

and supply cha<strong>in</strong><br />

• Needs of the population are not always easy to meet (self-sufficiency<br />

<strong>is</strong>sue).<br />

ETHICS OF THE PLASMA ORGANIZATION<br />

Ethical dimension can work both ways: as clearly expla<strong>in</strong>ed by Healy 8 , “Collection<br />

regimes do not simply <strong>in</strong>crease or decrease the donation rate along a slid<strong>in</strong>g scale. <strong>The</strong>y<br />

shape the k<strong>in</strong>d of activity that blood donation <strong>is</strong>. How you organize a blood supply<br />

system not only affects how much you collect and who you get it from, it shapes the<br />

character of donation”.


<strong>KCE</strong> Reports 120 Plasma 11<br />

<strong>The</strong>refore, it <strong>is</strong> of key importance to consider blood or plasma collection system not<br />

only from a technical po<strong>in</strong>t of view, but also from an ethical po<strong>in</strong>t of view, s<strong>in</strong>ce each<br />

option – whatever it <strong>is</strong>- <strong>is</strong> apt to have a major impact on the ethical dimension on<br />

donation and thus on donors’ behaviour and <strong>in</strong>directly on donors’ motivation as such.<br />

Given th<strong>is</strong> background, four options can theoretically be considered:<br />

• A purely market-driven system: not affordable so far given the<br />

<strong>in</strong>stitutional European context described above. Besides it would require<br />

the fitt<strong>in</strong>g <strong>in</strong>vestments.<br />

• A solidarity-driven system: requires a strong social bond and can be easily<br />

implemented <strong>in</strong> smaller communities. In fact only strongly bound<br />

communities whose members identify themselves <strong>with</strong> the same core<br />

values can perform such a system and rely on it..<br />

• A purely-voluntary system: “gift-fet<strong>is</strong>h<strong>is</strong>m”. However such a system does<br />

not seem to be reliable, as a matter of pr<strong>in</strong>ciple.<br />

Us<strong>in</strong>g <strong>in</strong>centives but reta<strong>in</strong><strong>in</strong>g the “gift-like” features of the donation: the latter option<br />

money as such <strong>is</strong> not an <strong>in</strong>centive, but th<strong>is</strong> does not exclude f<strong>in</strong>ancial compensation. <strong>The</strong><br />

latter option which <strong>is</strong> used <strong>in</strong> Austria or Germany for plasma donation ra<strong>is</strong>es specific<br />

problems as they can be seen as “borderl<strong>in</strong>e systems” from a purely ethical po<strong>in</strong>t of<br />

view. Clear-cut d<strong>is</strong>t<strong>in</strong>ction between of <strong>in</strong>centive Vs remuneration <strong>is</strong> not always easy to<br />

make.<br />

<strong>The</strong> pr<strong>in</strong>ciple of voluntary unpaid donation<br />

Over the last decades, all the key <strong>in</strong>stitutions <strong>in</strong>volved <strong>in</strong> blood and plasma donation<br />

have reasserted that profit as such must not be a motive for donation. Step by step, the<br />

pr<strong>in</strong>ciple of unpaid donation has been ethical standard for the countries of the European<br />

Union. Th<strong>is</strong> pr<strong>in</strong>ciple <strong>is</strong> officially mentioned by foremost <strong>in</strong>ternational <strong>in</strong>stitutions, and<br />

thus accepted by Member States of these <strong>in</strong>stitutions:<br />

• International Red Cross and Red Crescent Societies / Core resolutions<br />

and guidel<strong>in</strong>es on voluntary non remunerated blood donation: “F<strong>in</strong>ancial<br />

profit must never be a motive for the donors or those responsible for<br />

collect<strong>in</strong>g the donation. Voluntary, non remunerated donors should<br />

always be encouraged”<br />

• Council of Europe / Art 2 of the European Conference N. R (95) 14:<br />

“Donation <strong>is</strong> considered as voluntary and non remunerated” (even if small<br />

tokens, refreshments, and reimbursement of travel costs are compatible<br />

<strong>with</strong> voluntary non remunerated donation).<br />

• World Health Organization: “Safe blood donors are the cornerstone of<br />

safe and adequate supply of blood and blood products. <strong>The</strong> safest blood<br />

donors are voluntary non remunerated blood donors from low-r<strong>is</strong>k<br />

populations”.<br />

• Charter of Fundamental Rights of the European Union (Art 3): <strong>The</strong> right<br />

to the <strong>in</strong>tegrity of the person <strong>in</strong>volves “<strong>The</strong> prohibition on mak<strong>in</strong>g the<br />

human body and its parts as such a source of f<strong>in</strong>ancial ga<strong>in</strong>”.<br />

• Eventually, EU Directive 2002/98 Art 20 (opposable to all EU Member<br />

States) officially states that “Voluntary and unpaid blood donation are a<br />

factor which can contribute to high safety standards for blood and blood<br />

components and therefore to the protection of human health”.<br />

What emerges from all these statements <strong>is</strong> that blood and blood components are a<br />

subject of great ethical importance for the <strong>in</strong>ternational and EU level. From an ethical<br />

po<strong>in</strong>t of view, the pr<strong>in</strong>ciple of voluntary unpaid donation <strong>is</strong> now accepted as the<br />

cornerstone of the donation policy <strong>in</strong> all EU countries. Th<strong>is</strong> <strong>is</strong> a key difference <strong>with</strong><br />

other countries –especially the United States- where blood and plasma donation can be<br />

remunerated (even if it <strong>is</strong> not always remunerated).


12 Plasma <strong>KCE</strong> Reports 120<br />

<strong>The</strong> pr<strong>in</strong>ciple of unpaid donation <strong>is</strong> of key importance for the practical and technical<br />

organization of blood donation, as the ma<strong>in</strong> po<strong>in</strong>ts of the EU ethical and regulatory<br />

framework should rema<strong>in</strong> stable over the next years.<br />

Key po<strong>in</strong>ts<br />

• Pr<strong>in</strong>ciples underp<strong>in</strong>n<strong>in</strong>g blood and plasma donation are specific to th<strong>is</strong> k<strong>in</strong>d<br />

of donation. Mak<strong>in</strong>g the best use of donated blood or plasma can be seen as<br />

an ethical duty.<br />

• Ethical donation <strong>is</strong> not contradictory <strong>with</strong> a concept of compensation or<br />

other <strong>in</strong>centives, <strong>with</strong><strong>in</strong> strict limits.<br />

• It must be borne <strong>in</strong> m<strong>in</strong>d that <strong>in</strong> countries were compensation <strong>is</strong> applied,<br />

plasma donors are generally younger, more educated, and less <strong>in</strong>volved <strong>in</strong><br />

professional life than whole blood donors. Conversely, <strong>in</strong> countries where no<br />

f<strong>in</strong>ancial compensation <strong>is</strong> provided no clear d<strong>is</strong>t<strong>in</strong>ction, <strong>in</strong> terms of donors’<br />

profile, has been identified so far.<br />

2.1.2 Plasma collection <strong>in</strong> Belgium<br />

2.1.2.1 Current legal framework<br />

In Belgium, as <strong>in</strong> any country, blood and plasma donation can be considered as an<br />

<strong>in</strong>dividual gift or a good deed, based on personal motives and/or beliefs (altru<strong>is</strong>m or any<br />

philosophical or religious belief) but also as a collective commitment, especially <strong>in</strong> a<br />

professional context.<br />

For th<strong>is</strong> reason, mak<strong>in</strong>g public <strong>in</strong>stitutions and private firms (SMEs or bigger firms)<br />

aware of th<strong>is</strong> problem and mobiliz<strong>in</strong>g their employees for blood donation has been one<br />

of the most important m<strong>is</strong>sions of the Red Cross over the last decades.<br />

However, the situation of the employees <strong>is</strong> utterly different, whether they work <strong>in</strong> a<br />

private or a public context.<br />

Private Law Contracts<br />

<strong>The</strong> Belgian Private Work Contract Act (3 rd July 1978) sets out all the key rules<br />

concern<strong>in</strong>g the rights and duties of employers and employees. Th<strong>is</strong> Act addresses the<br />

different types of contract (worker’s contract, employee’s contract, sales<br />

representative, etc…) and covers the whole range of traditional work law <strong>is</strong>sues.<br />

However, it rema<strong>in</strong>s silent about possible leave or days off for blood or plasma<br />

donation. Legally speak<strong>in</strong>g, specific prov<strong>is</strong>ions, measures or arrangements can be set out<br />

only <strong>in</strong> the policies and procedures of each firm, but actual implementation of these<br />

measures (or arrangements) <strong>is</strong> left to the employer’s d<strong>is</strong>cretion.<br />

<strong>The</strong> employees are generally allowed, <strong>in</strong> th<strong>is</strong> exceptional case, to leave the office just for<br />

the time spent for donation, (generally between 1 and 2 hours) but may be requested to<br />

make up for the “time lost” (“lost” from the employer’s po<strong>in</strong>t of view).<br />

In practice, blood or plasma collection <strong>is</strong> often performed by the Red Cross’s teams<br />

dur<strong>in</strong>g or around a lunch pause, and employees hardly ever benefit from specific leave<br />

for donation.<br />

Public Law Contracts<br />

Virtually all the Belgian public law <strong>in</strong>stitutions have set out specific prov<strong>is</strong>ions, measures<br />

or arrangements <strong>in</strong> the employee’s contracts to enable them to benefit from specific<br />

leave or days off for “philanthropic purposes” which covers, <strong>in</strong>ter allia, blood and<br />

plasma donation (as well as bone marrow and t<strong>is</strong>sue donation). However, regulatory<br />

rules vary widely across <strong>in</strong>stitutions and regions, as described below:

DUTCH SPEAKING INSTITUTIONS<br />

Flem<strong>is</strong>h Region [13 JANUARY 2006. - Arrêté du Gouvernement flamand fixant le statut<br />

du personnel des services des autorités flamandes (Art 79)].<br />

Employees can be awarded a one day leave for blood, plasma or platelet donation,<br />

(<strong>with</strong><strong>in</strong> the limit of 1 day per month).<br />

FEDERAL LEVEL<br />

Federal level: “Day-Off or leave for philanthropic purposes” [9 December 1999. –<br />

Circulaire n° 487 relative à l'octroi d'une d<strong>is</strong>pense de service pour le don de sang, de<br />

plaquettes et de plasma sangu<strong>in</strong> (Art.42)].<br />

As a general rule, one day off for blood, platelet or plasma donation <strong>is</strong> awarded to the<br />

employee (Maximum: 4 days yearly). As far as plasma donation <strong>is</strong> concerned, employees<br />

are allowed to start the work day 1h54 later or to leave the office 1h54 sooner than<br />

usual.<br />

Key po<strong>in</strong>ts<br />

• From a purely legal po<strong>in</strong>t of view, there are no specific <strong>in</strong>centives to get<br />

private firms’ employees <strong>in</strong>volved <strong>in</strong>to donation<br />

• Conversely, regulatory framework <strong>is</strong> more favourable to public law<br />

employees, but rewards are utterly status-dependant.

2.1.2.2 Collected Quantities<br />

N<strong>in</strong>ety six percent of the blood and plasma donations <strong>in</strong> Belgium are collected by the<br />

Red Cross, which has been placed under the responsibility of the Belgian Red Cross<br />

s<strong>in</strong>ce its <strong>in</strong>ception <strong>in</strong> 1935. Four non Red Cross blood centres, at Charleroi Hospital<br />

and UCL Hospital Mont-God<strong>in</strong>ne, AZ S<strong>in</strong>t-Jan Brugge and the Service militaire du sang<br />

account for the rema<strong>in</strong><strong>in</strong>g blood collections. All donations are made by voluntary noncompensated<br />

donors, although some donors (from public sector) may receive time off<br />

work <strong>in</strong> addition to the time for donation. Although the Red Cross collects donations<br />

by plasmapheres<strong>is</strong> (source plasma), the bigger part of plasma <strong>in</strong>tended for fractionation<br />

<strong>is</strong> recovered plasma (from whole blood donations). Th<strong>is</strong> <strong>report</strong> focuses solely on the<br />

two organizations which form the “transfusion service”: <strong>The</strong> SFS = le Service<br />

Francophone du Sang and the VDB = De Vlaamse Dienst voor het Bloed.<br />

Table 1 and figure 1 show the trend <strong>in</strong> donations of whole blood and plasmapheres<strong>is</strong><br />

from 2000 to 2008. We note that the overall number of donations of whole blood <strong>is</strong><br />

very stable between the start and end of the period under review. However, th<strong>is</strong><br />

stability between these two dates (2000 and 2008) obscures the fall at the start of the<br />

period (from 513 762 donations <strong>in</strong> 2000 to 503 247 <strong>in</strong> 2003 and the strong growth (+<br />

4.7%) <strong>in</strong> 2004. S<strong>in</strong>ce then, the number of donations fell aga<strong>in</strong> before recover<strong>in</strong>g <strong>in</strong> 2008.<br />

Compar<strong>in</strong>g the trend <strong>in</strong> the <strong>French</strong>-speak<strong>in</strong>g section of the Red Cross (SFS) <strong>with</strong> that of<br />

the Dutch-speak<strong>in</strong>g section (VDB), we f<strong>in</strong>d a contrast<strong>in</strong>g situation result<strong>in</strong>g <strong>in</strong> stability<br />

from a reduction of more than 11 000 units for the VDB offset by a r<strong>is</strong>e of almost<br />

11 000 units for the SFS, which <strong>is</strong> partially artificial as it follows the <strong>in</strong>tegration of two<br />

<strong>in</strong>dependent centres by the SFS (the transfusion centre <strong>in</strong> Brussels <strong>in</strong> 2003 and the<br />

Hust<strong>in</strong> centre <strong>in</strong> 2004) <strong>in</strong> the SFS activities. As for the number of plasmapheres<strong>is</strong><br />

donations, the trend <strong>is</strong> clearly downwards, -56% for the VDB and -63% for the SFS over<br />

the period <strong>in</strong> question as a whole. It seems that the drop <strong>in</strong> the number of donations of<br />

source plasma <strong>is</strong> l<strong>in</strong>ked to the closure of plasmapheres<strong>is</strong> centres. Globally, the number<br />

of donors <strong>is</strong> quite stable dur<strong>in</strong>g the last three years (+ 2%), result<strong>in</strong>g from a comb<strong>in</strong>ation<br />

of a decreas<strong>in</strong>g for the VDB (-1.5%) and a substantial <strong>in</strong>creas<strong>in</strong>g for the SFS (+9%).<br />

It seems that the collection of plasma <strong>is</strong> a quite flexible activity. Indeed <strong>in</strong> 2004-2005,<br />

the demand has <strong>in</strong>creased and SFS and VDB have collected more plasma from<br />

plasmapheres<strong>is</strong> to meet the <strong>in</strong>creased demand.

We have calculated the average volume of donation of plasma for the recovered plasma<br />

(RP) and the source plasma (SP). <strong>The</strong> first one shows a relatively constant trend,<br />

around 0.210 ml per donation for the SFS. Th<strong>is</strong> volume has lightly decreased for VDB<br />

(0.254 <strong>in</strong> 2000 and 0.206 <strong>in</strong> 2008). <strong>The</strong> average volume of plasma from plasmapheres<strong>is</strong><br />

has strongly <strong>in</strong>creased s<strong>in</strong>ce 2004 for the two sections of the Red Cross.<br />

We also noticed that the average number of donations of whole blood per donor <strong>is</strong><br />

stable (Table 4), for the VDB and the SFS, dur<strong>in</strong>g the 2003-2008 period (around 2.2)<br />

(<strong>The</strong> average number of donations was obta<strong>in</strong>ed by divid<strong>in</strong>g the number of donations by<br />

the number of donors). Nevertheless, the evolution <strong>is</strong> different concern<strong>in</strong>g the average<br />

number of plasmapheres<strong>is</strong> donations. Whereas th<strong>is</strong> number rema<strong>in</strong>ed stable for the SFS<br />

(5.7), it decreased for the VDB (7.0 <strong>in</strong> 2003 and 4.5 <strong>in</strong> 2008).<br />

<strong>The</strong> figures presented do not make differences between the volume of plasma collected<br />

from plasmapheres<strong>is</strong> and the volume of plasma collected from cytapheres<strong>is</strong>. <strong>The</strong>se two<br />

k<strong>in</strong>ds of plasma are considered as source plasma and are sold to the CAF – DCF.<br />

F<strong>in</strong>ally, we present the average volume of plasma per donation for the RP and the SP.<br />

For the VDB, we received directly these average volumes per year. For the SFS, we<br />

have calculated the average by subtract<strong>in</strong>g the assumed volume of plasma collected by<br />

cytapheres<strong>is</strong> (hypothes<strong>is</strong> of 200 ml per donation) of the total volume of source plasma<br />

collected. <strong>The</strong> results are quite similar to those of the VDB. <strong>The</strong> <strong>in</strong>crease <strong>in</strong> the<br />

average volume s<strong>in</strong>ce 2004 <strong>is</strong> noticeable for the two sections of the Red Cross.<br />

It seems that the substantial <strong>in</strong>crease of SP collection <strong>in</strong> 2004 <strong>is</strong> the result of at least<br />

two factors:<br />

• A switch of practices concern<strong>in</strong>g the ‘therapeutic plasma’<br />

• A response to a <strong>in</strong>crease of the <strong>in</strong>ternational demand by a <strong>in</strong>crease of the<br />

average volume per donation<br />

Until 2004, the plasma used by hospitals for therapeutic purposes (used <strong>in</strong> the<br />

treatment of some bleed<strong>in</strong>gs) stemmed from plasmapheres<strong>is</strong> plasma, which was<br />

delivered by the Red Cross. From 2004 onwards, the Red Cross was authorized to<br />

manufacture th<strong>is</strong> therapeutic plasma, straight from its own whole blood. As a result of<br />

th<strong>is</strong> regulatory change:<br />

• <strong>The</strong> correspond<strong>in</strong>g volume of whole blood was tapped by the Red Cross<br />

(from the ex<strong>is</strong>t<strong>in</strong>g collected volume), <strong>in</strong> order to manufacture th<strong>is</strong><br />

therapeutic plasma.<br />

• Likew<strong>is</strong>e, the volume of plasmapheres<strong>is</strong> plasma, which was formerly<br />

delivered to hospitals for therapeutic purposes, was then transferred to<br />

the CAF-DCF.<br />

Th<strong>is</strong> switch <strong>in</strong> practices <strong>is</strong> probably one of the factors expla<strong>in</strong><strong>in</strong>g the sudden r<strong>is</strong>e <strong>in</strong> the<br />

volume of plasmapheres<strong>is</strong> plasma delivered to the CAF-DCF, and simultaneously the<br />

sudden decrease <strong>in</strong> the volume of whole blood plasma delivered to the CAF-DCF <strong>in</strong> the<br />

year 2004. An other factor <strong>is</strong> the change <strong>in</strong> global demand, as shown for the 2004-2005<br />

<strong>in</strong>crease (Table 2).

Key po<strong>in</strong>ts<br />

• <strong>The</strong> Red Cross collects 96% of all blood and plasma <strong>in</strong> Belgium<br />

• <strong>The</strong> number of donors of whole blood <strong>is</strong> relatively stable for the Dutchspeak<strong>in</strong>g<br />

community and slightly up <strong>in</strong> the <strong>French</strong>-speak<strong>in</strong>g community<br />

• <strong>The</strong> fall <strong>in</strong> the number of donations collected ma<strong>in</strong>ly affects source plasma (-<br />

58% between 2000 and 2008)<br />

• In 2008, the number of donations of whole blood showed a slight upturn for<br />

the Dutch-speak<strong>in</strong>g community and confirmation of the r<strong>is</strong>e <strong>in</strong> the <strong>French</strong>speak<strong>in</strong>g<br />

community<br />

• <strong>The</strong> total volume of plasma has strongly decreased between 2000 and 2008,<br />

by - 24 % (- 14 % for RP and - 41 % for SP)<br />

• If the number of donation of plasmapheres<strong>is</strong> per donor has decreased s<strong>in</strong>ce<br />

2000, the volume per donation has strongly <strong>in</strong>creased s<strong>in</strong>ce 2004<br />

2.1.2.3 <strong>The</strong> price of plasma<br />

<strong>The</strong> plasma (from plasmapheres<strong>is</strong>, cytapheres<strong>is</strong> (SP) and whole blood (RP)) <strong>is</strong> sold by<br />

the Red Cross to a fractionation company – the CAF-DCF (Centrale Afdel<strong>in</strong>g voor<br />

Fractioner<strong>in</strong>g - Département Central de Fractionnement) – at a mutually agreed price<br />

and quantity each year. Th<strong>is</strong> agreement, dat<strong>in</strong>g back to 26 February 1998, also sets out<br />

the technical criteria for delivery a . <strong>The</strong> price of the RP purchased by the CAF – DCF<br />

has rema<strong>in</strong>ed unchanged s<strong>in</strong>ce 1998 (53.30 euros). In 1998, the CAF – DCF was<br />

granted a price cut for the purchase of SP s<strong>in</strong>ce 1998 (53.3 euros <strong>in</strong> place of 78.09<br />

euros), <strong>in</strong> order to protect its competitiveness on the <strong>in</strong>ternational market and to<br />

ensure the fund<strong>in</strong>g of the technological progress of its activities. In 2003, the price was<br />

<strong>in</strong>creased.<br />

a In compliance <strong>with</strong> the 5 July 1994 Law , it <strong>is</strong> a matter of confirm<strong>in</strong>g that plasma must stem, as a matter<br />

of pr<strong>in</strong>ciple, from voluntary and non remunerated donors


18 Plasma <strong>KCE</strong> Reports 120<br />

Year<br />

Table 5 shows the trend <strong>in</strong> the price of RP and SP from 1997 to 2007 <strong>with</strong> which we<br />

compare the trend <strong>in</strong> <strong>in</strong>ternational prices found <strong>in</strong> an unpubl<strong>is</strong>hed PPTA document.<br />

Over the years for which data are <strong>available</strong> (2002, 2003, 2004 and 2006, 2007), it<br />

appears that the price of RP sold by the Red Cross to the CAF-DCF (53.07 euros)<br />

represents a very competitive price compared <strong>with</strong> the prices be<strong>in</strong>g paid on the<br />

<strong>in</strong>ternational market. As a corollary, th<strong>is</strong> price represents a loss of potential revenue<br />

for the Red Cross. For SP, the situation prior to 2003 (given the <strong>in</strong>ternational price <strong>in</strong><br />

2002) cannot have been profitable for the Red Cross. After the r<strong>is</strong>e <strong>in</strong> price <strong>in</strong> 2003,<br />

from 53.30 to 78.09, the situation has improved: the amount received by the RC (price<br />

+ subsidy, see next section) <strong>is</strong> systematically higher than the <strong>in</strong>ternational price,<br />

accord<strong>in</strong>g to the sources of Table 5.<br />

In view of the small difference between the <strong>in</strong>ternational price and the amount received<br />

by the Red Cross (price + subsidy), it <strong>is</strong> vital to confirm th<strong>is</strong> analys<strong>is</strong> by compar<strong>in</strong>g it<br />

<strong>with</strong> other sources of <strong>in</strong>ternational prices. In Table 6, we show an average price of<br />

source plasma amounts to 106 euros.<br />

As highlighted by Verhaegen, 9 the r<strong>is</strong>e <strong>in</strong> price agreed <strong>in</strong> 2003 should correspond to reestabl<strong>is</strong>h<strong>in</strong>g<br />

of the competitive position of the CAF-DCF, which had completed its<br />

<strong>in</strong>vestment <strong>in</strong> build<strong>in</strong>gs (construction on the site at Neder-Over-Heembeeck).<br />

However, reta<strong>in</strong><strong>in</strong>g the subsidy for the Red Cross was <strong>with</strong>out doubts l<strong>in</strong>ked to the<br />

<strong>in</strong>adequate price paid by the CAF-DCF to cover the cost of plasma collection. <strong>The</strong><br />

validity of the above results depends critically on <strong>in</strong>ternational prices. Dur<strong>in</strong>g a meet<strong>in</strong>g<br />

of external experts, we obta<strong>in</strong>ed different <strong>in</strong>formation that <strong>in</strong>ternational prices were<br />

around 75 euros for RP and 90 euros for SP, <strong>in</strong>clud<strong>in</strong>g the price of the NAT test (see<br />

below). Other sources 10 appear to confirm that the price paid by the CAF-DCF for<br />

whole blood plasma <strong>is</strong> well below the <strong>in</strong>ternational price and that the average price that<br />

the Red Cross could obta<strong>in</strong> for plasma from plasmapheres<strong>is</strong> <strong>is</strong> slightly higher than the<br />

price it currently receives, <strong>in</strong>clud<strong>in</strong>g the subsidy (Table 6).<br />

• <strong>The</strong> Red Cross sells the collected source plasma to the CAF – DCF at a price<br />

determ<strong>in</strong>ed <strong>in</strong> a contract between the two <strong>in</strong>stitutions<br />

• We cannot determ<strong>in</strong>e if the price received <strong>is</strong> higher or lower than the price<br />

determ<strong>in</strong>ed by the demand and supply of plasma on the <strong>in</strong>ternational<br />

2.1.2.4 Subsidy for source plasma<br />

S<strong>in</strong>ce 1998, the Red Cross receives a subsidy of 24.79 euros per litre of source plasma<br />

(from plasmapheras<strong>is</strong> and cytapheras<strong>is</strong>) sold to the CAF-DCF. <strong>The</strong> subsidy <strong>is</strong> f<strong>in</strong>anced<br />

by a supplement of 0.10% paid on compulsory car <strong>in</strong>surance premiums.<br />

<strong>The</strong>se prov<strong>is</strong>ions therefore make a sometimes considerable d<strong>is</strong>t<strong>in</strong>ction between the<br />

price on the Belgian market and the price on the <strong>in</strong>ternational market. As showed <strong>in</strong><br />

table 5, the Red Cross receives a fixed subsidy per liter of source plasma<br />

(plasmapheres<strong>is</strong> and cytapheras<strong>is</strong> plasma) sold to the CAF-DCF. <strong>The</strong> received subsidy<br />

had to offset a reduction <strong>in</strong> the sale price of the same amount.<br />

Key po<strong>in</strong>ts<br />

• S<strong>in</strong>ce 1998, the CAF – DCF benefits from a reduction of the price of source<br />

plasma<br />

• To compensate th<strong>is</strong> reduction, the Red Cross receives a subsidy from the<br />

State<br />

2.1.2.5 Subsidy for NAT test<strong>in</strong>g<br />

<strong>The</strong> transfusion establ<strong>is</strong>hments receive a budget that covers the cost of nucleic acid<br />

tests (NAT) HIV1 and HCV test<strong>in</strong>g on whole blood donations. <strong>The</strong> budget takes the<br />

form of a prov<strong>is</strong>ion that <strong>is</strong> subsequently topped up or clawed back depend<strong>in</strong>g on the<br />

number of tests actually performed. <strong>The</strong>se budgets are determ<strong>in</strong>ed by Royal Decrees.<br />

<strong>The</strong> establ<strong>is</strong>hments concerned are the two sections of the Red Cross, the non-profit<br />

organ<strong>is</strong>ation ‘transfusion du sang’ <strong>in</strong> Charleroi, the non-profit organ<strong>is</strong>ation<br />

‘Etabl<strong>is</strong>sement de transfusion de Mont-God<strong>in</strong>ne’ and the AZ S<strong>in</strong>t-Jan <strong>in</strong> Bruges. <strong>The</strong><br />

f<strong>in</strong>al balance of the subsidy granted, to be received or reimbursed, <strong>is</strong> calculated on the<br />

total number of successful samples collected, effectively carried out and tested us<strong>in</strong>g the<br />

NAT tests for HIV1 and HCV.


20 Plasma <strong>KCE</strong> Reports 120<br />

Th<strong>is</strong> number of units collected and testes must be justified by the <strong>in</strong>voices relat<strong>in</strong>g to<br />

these tests and certified by an <strong>in</strong>ternal or external auditor. <strong>The</strong> def<strong>in</strong>itive balance of the<br />

<strong>in</strong>stitutions <strong>is</strong> calculated follow<strong>in</strong>g the subm<strong>is</strong>sion of the support<strong>in</strong>g documents, which<br />

are sent to the Federal Agency for Medic<strong>in</strong>es and Health Products. In 2007, a sum of<br />

14.00 EUR was paid for each test actually conducted. <strong>The</strong> Royal Decree states that the<br />

subsidies granted can under no circumstances exceed the real costs <strong>in</strong>curred.<br />

<strong>The</strong> remuneration procedure def<strong>in</strong>ed for the NAT test licence <strong>is</strong> as follows: systematic<br />

collection of royalties for the test manufacturer - reflect<strong>in</strong>g the number of usable<br />

results; for example if a s<strong>in</strong>gle test <strong>is</strong> used for 10 pouches of blood (pool test<strong>in</strong>g), the<br />

number of royalties will be equal to ten although only one test has been used if negative<br />

result). In addition, the subsidy depends on the number of units successfully collected<br />

and the number of tests certified <strong>in</strong> an <strong>in</strong>voice. As mentioned above, these are l<strong>in</strong>ked to<br />

the number of usable results and not necessarily to the number of units used as<br />

reagents. Th<strong>is</strong> means that if a pool<strong>in</strong>g process <strong>is</strong> used (which seems to be the case for<br />

the Red Cross), the amount of the subsidies may be d<strong>is</strong>sociated from the number of<br />

reagents purchased. For the Red Cross, the system of pool test<strong>in</strong>g may lead to a sav<strong>in</strong>g<br />

<strong>in</strong> manpower.<br />

Key po<strong>in</strong>ts<br />

• <strong>The</strong> collectors of whole blood receive a specific subsidy for the NAT tests to<br />

detect HIV1 and HCV<br />

• <strong>The</strong> Red Cross uses a system of pool<strong>in</strong>g to carry out these tests, likely sav<strong>in</strong>g<br />

<strong>in</strong> manpower<br />

• <strong>The</strong> firm sell<strong>in</strong>g these tests receives royalties <strong>in</strong> function of the number of<br />

usable tests (not necessarily of the number of tests carried out)<br />

For the subsidies, we have taken the data from the <strong>in</strong>ternal <strong>report</strong>s of the SFS for the<br />

<strong>report</strong>s, we have used the official data, which fix the subsidy at 24.79 euros.<br />

<strong>The</strong> head<strong>in</strong>gs for costs specific to plasmapheres<strong>is</strong> (donor management, collection and<br />

laboratory) are constantly r<strong>is</strong><strong>in</strong>g. <strong>The</strong> organ<strong>is</strong>ation costs <strong>in</strong> 2007 constitute 23% of total<br />

costs; given that these costs are allocated to all organ<strong>is</strong>ation costs for ‘plasmapheres<strong>is</strong>’, a<br />

part of the negative result of the compar<strong>is</strong>on between costs and prices for th<strong>is</strong> activity<br />

may require d<strong>is</strong>cussion concern<strong>in</strong>g th<strong>is</strong> allocation. If a smaller part of the organ<strong>is</strong>ation<br />

costs was allocated to plasmapheres<strong>is</strong>, the total costs would be reduced accord<strong>in</strong>gly.<br />

Key po<strong>in</strong>ts<br />

• <strong>The</strong> difference between the cost of a litre of plasma from plasmapheres<strong>is</strong><br />

and the price received for th<strong>is</strong> litre of plasma depends on the allocation of<br />

the structure costs on th<strong>is</strong> activity<br />

• We did not receive the cost structure used by the VDB

2.1.3.1 Plasma collection <strong>in</strong> Germany<br />

General Po<strong>in</strong>ts<br />

Blood and plasma donation are organized <strong>with</strong><strong>in</strong> a strict legal framework def<strong>in</strong>ed by law.<br />

<strong>The</strong> Transfusion Act (Transfusionsgesetz- TFG) 11 sets out the key pr<strong>in</strong>ciples and rules<br />

that blood donation must follow: donor selection, <strong>in</strong>formation, blood tests and blood<br />

quality control, f<strong>in</strong>ancial compensation, epidemiology data, data protection, follow-up of<br />

blood donations.<br />

Pr<strong>in</strong>ciple of unpaid donation and f<strong>in</strong>ancial compensation<br />

Concern<strong>in</strong>g f<strong>in</strong>ancial <strong>is</strong>sues, the key pr<strong>in</strong>ciple <strong>is</strong> that blood donation <strong>in</strong> general (full blood<br />

and/or plasma) must rema<strong>in</strong> unpaid. However, f<strong>in</strong>ancial compensation can be awarded<br />

to the donor (“may”, as it <strong>is</strong> not mandatory), provided it <strong>is</strong> directly and clearly<br />

connected <strong>with</strong> donation-related costs, <strong>in</strong> practice: travel costs, car park, and time spent<br />

for donation.<br />

<strong>The</strong> maximum amount of th<strong>is</strong> f<strong>in</strong>ancial compensation has been set out by the German<br />

leg<strong>is</strong>lation, ie 25€. However, as expla<strong>in</strong>ed further <strong>in</strong> th<strong>is</strong> <strong>report</strong>, each <strong>in</strong>stitution enjoys a<br />

complete freedom <strong>in</strong> th<strong>is</strong> field: whereas some do reward donors (eg: Private Plasma<br />

donation centres), some other do not (eg: German Red Cross Institutions). <strong>The</strong> amount<br />

of the compensation <strong>is</strong> left to each <strong>in</strong>stitution’s d<strong>is</strong>cretion, <strong>with</strong><strong>in</strong> the limit of 25€.<br />

Free Competition between <strong>in</strong>stitutions of blood and plasma donation<br />

Unlike <strong>in</strong> other countries, blood donation <strong>is</strong> not organized on a monopoly bas<strong>is</strong>. Public<br />

and private <strong>in</strong>stitutions are allowed to compete <strong>with</strong> each other, <strong>in</strong> the field of blood<br />

donation and plasma donation alike. Three <strong>in</strong>stitutions have emerged <strong>in</strong> the field of<br />

donation: University-hospitals, German Red Cross Institutions, and Private Donation<br />

Centres.<br />

However, it <strong>is</strong> also important to underl<strong>in</strong>e that these <strong>in</strong>stitutions, although compet<strong>in</strong>g<br />

<strong>with</strong> each other <strong>in</strong> day-to-day donation are required to cooperate <strong>with</strong> each other <strong>in</strong><br />

case of shortage (mutual delivery of blood, plasma, or blood and plasma products).<br />

Th<strong>is</strong> support service was already implemented on the field <strong>in</strong> 2007, when 300 000<br />

pockets of Red Cells Concentrate have been shipped by the Red Cross to the<br />

University-Hospital donation centres.<br />

In practice, as expla<strong>in</strong>ed further <strong>in</strong> th<strong>is</strong> <strong>report</strong>, plasma collection as such <strong>is</strong> largely<br />

performed by purely private or <strong>in</strong>dustry-driven <strong>in</strong>stitutions.<br />

Cl<strong>in</strong>ical Issues: German Guidel<strong>in</strong>es of 2005 on plasmapheres<strong>is</strong> and ongo<strong>in</strong>g studies<br />

Specific “Richtl<strong>in</strong>ien” (mandatory guidel<strong>in</strong>es) have been <strong>is</strong>sued, and titled: “Guidel<strong>in</strong>es<br />

(haemotherapy)” Establ<strong>is</strong>hed by the German Order of Doctors and agreed <strong>with</strong> the<br />

<strong>The</strong>se guidel<strong>in</strong>es have been def<strong>in</strong>ed by the National Order of Doctors and the Paul<br />

Ehrlich Institut. However, <strong>in</strong> today’s form, these guidel<strong>in</strong>es are not considered as utterly<br />

specific studies have been carried out (“Study on the Safety of Long-Term Intensive<br />

Plasmapheres<strong>is</strong> <strong>in</strong> Donors” also known as SIPLA I, and SIPLA II Studies”), <strong>in</strong> order to<br />

formulate new propositions on specific po<strong>in</strong>ts, and to improve the volume of donations,<br />

while ensur<strong>in</strong>g the protection of the donor’s health.

Role of the German Red Cross (DRK) compared to private firms <strong>in</strong> the plasma<br />

collection <strong>in</strong>dustry<br />

Accord<strong>in</strong>g to the German leg<strong>is</strong>lation, free competition <strong>is</strong> allowed between a large<br />

number of <strong>in</strong>stitutions, public and private alike. Today’s picture of plasma collection <strong>in</strong><br />

Germany <strong>is</strong> very specific as purely private firms or <strong>in</strong>stitutions have been more and<br />

more <strong>in</strong>volved <strong>in</strong> th<strong>is</strong> field, over the last years. <strong>The</strong>se private firms resort to clearly<br />

customer-oriented and profit-centred strategies.<br />

An <strong>in</strong>-depth survey conducted by Robert Koch Institute on d<strong>is</strong>tribution of plasma<br />

collection <strong>in</strong> 2006. Th<strong>is</strong> survey focused on the number of plasma repeat donors. It<br />

clearly showed that the number of donors from <strong>in</strong>dustry-driven centres and private<br />

centres amount for more than 81.6% of the total number of plasma repeat donors. <strong>The</strong><br />

number of plasma repeat donors from the Red Cross <strong>is</strong> much smaller (10.4%). So <strong>is</strong> the<br />

number of repeat donors from Federal or municipal centres (8%).<br />

Consider<strong>in</strong>g the volume of plasma delivered for fractionation, approximately half of th<strong>is</strong><br />

volume comes from plasmapheres<strong>is</strong>. Th<strong>is</strong> <strong>is</strong> of key importance, as private centres<br />

(<strong>in</strong>dustry-driven centres or private donation centres) design specific strategies target<strong>in</strong>g<br />

plasma donors, whereas the Red Cross did not (ma<strong>in</strong>ly for h<strong>is</strong>torical reasons).<br />

All pr<strong>in</strong>ciples and rules detailed <strong>in</strong> the Appendix (see Appendix “Germany”) relat<strong>in</strong>g to<br />

the German Red Cross – especially the campaign and <strong>in</strong>formation material – are <strong>in</strong> use<br />

both for full blood and plasma collection. Indeed, no specific campaign has been<br />

designed for plasma donation as such, unlike <strong>in</strong> the <strong>in</strong>dustry-driven or private donation<br />

centres.<br />

Demographic dimension of plasma donation <strong>in</strong> Germany: survey of Robert Koch<br />

<strong>in</strong>stitute<br />

<strong>The</strong> first objective of the survey was to conduct an <strong>in</strong>-depth analys<strong>is</strong> the demographic<br />

profile of plasma donors <strong>in</strong> Germany especially concern<strong>in</strong>g d<strong>is</strong>tribution of age groups<br />

among plasma donors, <strong>in</strong> each type of <strong>in</strong>stitutions (Website: http://www.rki.de/ ).<br />

<strong>The</strong> f<strong>in</strong>al objective of the survey was to analyze the possible impact of demographic<br />

changes of the German population on plasma donation over the next decades.<br />

D<strong>is</strong>tribution of age groups for blood donors highlights the crucial role of young people<br />

<strong>in</strong> plasma donation, ie people younger than 44 and among them those below 25. As<br />

shown on the graph below d<strong>is</strong>tribution of age groups <strong>is</strong> clearly uneven:<br />

Over the next decades, the German general population will undergo major changes,<br />

especially <strong>in</strong> terms of age structure. <strong>The</strong> objective of the survey was to make a quick<br />

synthes<strong>is</strong> on the ma<strong>in</strong> demographic trends and to analyze their impact on the donors<br />

population. In l<strong>in</strong>e <strong>with</strong> the German regulation and the guidel<strong>in</strong>es mentioned above, the<br />

“Population <strong>with</strong><strong>in</strong> the donor age limits” <strong>is</strong> def<strong>in</strong>ed as people between 18 and 68.<br />

Based on the data of the German stat<strong>is</strong>tical office (Destat<strong>is</strong>) the size of th<strong>is</strong> population<br />

will evolve as below:

Figure 2: Demographic prospects <strong>in</strong> Germany 2006-2031 (Age d<strong>is</strong>tribution)<br />

Source: German Federal Stat<strong>is</strong>tical Office<br />

Divergence between these both trends has been clearly highlighted by Robert Koch<br />

Institute as an age<strong>in</strong>g population means an <strong>in</strong>crease of potential recipients. On the long<br />

term, it could ra<strong>is</strong>e major problems <strong>in</strong> terms of supply/demand. In order to prevent<br />

shortfalls <strong>in</strong> plasma supply, it <strong>is</strong> clear that the number of donors should be ra<strong>is</strong>ed over<br />

the whole population of potential donors (ie 18-68). Emphas<strong>is</strong> should also be laid on<br />

retention of donors. Private centres and <strong>in</strong>dustry-driven centres will face major<br />

difficulties unless they recruit a much large number of donors <strong>in</strong> higher age groups<br />

(above 35) than they do today.<br />

Further <strong>in</strong>formation on donation campaign and demographic <strong>is</strong>sues <strong>in</strong> Appendix<br />

“Germany”<br />

Key po<strong>in</strong>ts<br />

• Maxim<strong>is</strong>ation of <strong>in</strong>dividual donation volume <strong>is</strong> one of the key <strong>is</strong>sues of<br />

ongo<strong>in</strong>g studies <strong>in</strong> Germany.<br />

• Consider<strong>in</strong>g plasma delivered for fractionation, plasmapheres<strong>is</strong> plays an<br />

important role, and <strong>is</strong> largely performed by private centres.<br />

• Plasma donors’ profile <strong>is</strong> quite specific: younger, more-educated, less<br />

<strong>in</strong>volved <strong>in</strong> professional life, and less often married.<br />

• “Real World” communication campaigns and practical follow-up of donors<br />

<strong>with</strong> modern techniques are of key importance to improve retention of<br />

donors. Interface <strong>with</strong> the education system <strong>is</strong> also of paramount<br />

importance.<br />

• Great attention <strong>is</strong> paid to the demographic dimension to adjust recruitment<br />

and retention policy accord<strong>in</strong>gly.

2.1.3.2 Plasma collection <strong>in</strong> France<br />

H<strong>is</strong>torical Background<br />

For h<strong>is</strong>torical reasons, collection and fractionation activities have been clearly split<br />

between two different <strong>in</strong>stitutions:<br />

• Etabl<strong>is</strong>sement França<strong>is</strong> du Sang (EFS) for collection and vigilance activities<br />

(and other specific activities / see below)<br />

• Laboratoire França<strong>is</strong> de Fractionnement et de Biotechnologie (LFB) for<br />

fractionation activities, market<strong>in</strong>g of plasma-derived products, and<br />

Biotechnology R&D.<br />

In their own respective fields of activity, each of these <strong>in</strong>stitutions enjoys a monopoly.<br />

For practical reasons, both <strong>in</strong>stitutions have to work <strong>in</strong> connection under the<br />

superv<strong>is</strong>ion of public authorities. However, they are matters for different legal statuses.<br />

Safety and security requirements<br />

<strong>The</strong> AFSSAPS – Agence França<strong>is</strong>e de Sécurité Sanitaire des Produits de Santé <strong>French</strong><br />

Agency for the Safety of Health Products (Dec<strong>is</strong>ion of 6 November 2006) <strong>is</strong> <strong>in</strong> charge of<br />

safety, as described above <strong>in</strong> the <strong>report</strong><br />

Legal status and m<strong>is</strong>sions of the Etabl<strong>is</strong>sement França<strong>is</strong> du Sang -EFS<br />

LEGAL STATUS<br />

<strong>The</strong> EFS has been created <strong>in</strong> 2000, <strong>is</strong> a public-law body and compr<strong>is</strong>es one national head<br />

office and 17 regional branches. Key members of its Board of Adm<strong>in</strong><strong>is</strong>tration are<br />

representatives of the Department of Health, M<strong>in</strong><strong>is</strong>try of F<strong>in</strong>ance, and M<strong>in</strong><strong>is</strong>try of<br />

Research. Representatives of the Health Care Insurance Funds are also members of the<br />

Board. While be<strong>in</strong>g a public <strong>in</strong>stitution one must notice that the EFS does not receive<br />

any public subsidy (most of its resources stem from the sale of labile products to<br />

hospitals) See website:<br />

http://www.dondusang.net/rewrite/head<strong>in</strong>g/1.htm?idRubrique=1) .<br />

THE MISSIONS OF THE EFS<br />

<strong>The</strong>se m<strong>is</strong>sions have been set out by the <strong>French</strong> leg<strong>is</strong>lation as follows:<br />

• Collection of blood and plasma: See also Appendix “France” on collection<br />

<strong>is</strong>sues<br />

• Ensur<strong>in</strong>g self-sufficiency<br />

• Vigilance activities: ensur<strong>in</strong>g actual application of safety and quality<br />

• Delivery of labile products to hospitals for transfusion purposes<br />

• Delivery of plasma to the LFB for fractionation purposes (official delivery<br />

targets)<br />

• International cooperation activities

Legal Status and m<strong>is</strong>sions of the Laboratoire França<strong>is</strong> de Fractionnement et de<br />

LEGAL STATUS<br />

In 2005, LFB (formerly public-law structure) has been transformed <strong>in</strong>to a private-law<br />

firm (Edict of 28 July 2005) 13 . However, key members of the Board of Adm<strong>in</strong><strong>is</strong>tration<br />

are representatives of public authorities (Department of Health, M<strong>in</strong><strong>is</strong>try of F<strong>in</strong>ance),<br />

and the majority of the LFB’s shares rema<strong>in</strong>s <strong>in</strong> the hands of public stakeholders only.<br />

In today’s form, LFB <strong>is</strong> a hold<strong>in</strong>g company that controls two subsidiary companies:<br />

• LFB Biomédicaments (specialized <strong>in</strong> plasma fractionation and market<strong>in</strong>g of<br />

plasma-derived products).<br />

• LFB Biotechnologies (specialized <strong>in</strong> Biotechnology R&D)<br />

THE MISSIONS OF THE LFB<br />

LFB <strong>is</strong> specialized <strong>in</strong> the follow<strong>in</strong>g fields:<br />

• Immunology: primary immune deficiency, secondary immune deficiency,<br />

Kawasaki d<strong>is</strong>ease, Guilla<strong>in</strong>-Barré syndrome, etc..<br />

• Hemostasy / Clott<strong>in</strong>g factors: ma<strong>in</strong>ly von Willbrand and haemophilia<br />

• Anaesthesia / Resuscitation products<br />

• RD activities <strong>in</strong> the field of Biotechnology:<br />

• International activities: as most private firms of th<strong>is</strong> <strong>in</strong>dustry, LFB <strong>is</strong> also<br />

committed <strong>in</strong> <strong>in</strong>ternational activities, especially <strong>in</strong> plasma fractionation. As<br />

described below <strong>in</strong> the <strong>report</strong>, it plays an important role on the Brazilian<br />

market, as it will ass<strong>is</strong>t Brazilian stakeholders <strong>in</strong> sett<strong>in</strong>g up plasma<br />

fractionation facilities, and a susta<strong>in</strong>able supply cha<strong>in</strong>.<br />

Connection between the EFS towards the LFB<br />

As far as delivery of plasma <strong>is</strong> concerned, specific targets are fixed between EFS and LFB<br />

whereby, the volume of plasma to be delivered by EFS to the FFB <strong>is</strong> officially set out 14 .<br />

<strong>The</strong>se targets are opposable to the EFS. <strong>The</strong>refore, the key strategic objective of the<br />

latter <strong>is</strong> to keep up <strong>with</strong> the evolution of LFB supply needs. Delivery targets have<br />

evolved and will evolve as below (liters):<br />

Figure 3: EFS Delivery targets to LFB (2005-2011)<br />

Source: EFS Corporate data<br />

Th<strong>is</strong> key driver for the EFS <strong>is</strong> basically to <strong>in</strong>crease its plasma supply <strong>in</strong> order to meet the<br />

EFS needs, which thus <strong>in</strong>volves an <strong>in</strong>-depth reflection on the whole collection strategy<br />

and processes. Besides, the sale price of the plasma <strong>is</strong> fixed nationally by the<br />

Department of Health. Over the last years, it was reduced from 155 € to 135€ <strong>in</strong> 2007,<br />

and to 105€ <strong>in</strong> 2008. For all these reasons, the EFS steadily needs to improve its<br />

productivity (<strong>in</strong> terms of process) and also the total volume of collected plasma.<br />

In 2008:


<strong>KCE</strong> Reports 120 Plasma 27<br />

• 73% of plasma delivered to LFB stems from traditional whole blood<br />

technique.<br />

• 27% from other techniques: plasmapheres<strong>is</strong>, comb<strong>in</strong>ed apheres<strong>is</strong>, and<br />

mixed platelets concentrates (MPC).<br />

Cost control and EFS processes<br />

Costs Issues<br />

As mentioned above the EFS has to reach very demand<strong>in</strong>g delivery targets, under strict<br />

constra<strong>in</strong>ts, especially unilateral sale prices fix<strong>in</strong>g by the Departement of Health.<br />

<strong>The</strong>refore, the EFS <strong>is</strong> compelled to deliver an <strong>in</strong>creas<strong>in</strong>g volume of blood to LFB 630<br />

000 liters <strong>in</strong> 2006; 1,1 Millions liters scheduled for 2011.<br />

<strong>The</strong> ma<strong>in</strong> problems for EFS managers are obviously to ensure overall f<strong>in</strong>ancial balance of<br />

collection activities, but also to avoid d<strong>is</strong>crepancies between the collection costs of<br />

blood and plasma. One of ma<strong>in</strong> driver for EFS’s dec<strong>is</strong>ion makers <strong>is</strong> to cut down<br />

apherese plasma production costs, step by step, thanks to an <strong>in</strong>creased collection of<br />

actually collected plasma and a rationalization of collection techniques.<br />

DISTRIBUTION BETWEEN APHERESE PLASMA AND RECOVERED PLASMA<br />

In 2007, around 20% of plasma comes from apherese plasma whereas 80% rema<strong>in</strong>s<br />

recovered plasma. <strong>The</strong> objective of the EFS <strong>is</strong> to ra<strong>is</strong>e the share of apherese plama over<br />

the next year, for technical reasons (ma<strong>in</strong>ly <strong>in</strong>creased frequency of donations).<br />

Frequency of donation <strong>is</strong> all the more important as the proportion of donors <strong>in</strong> the<br />

<strong>French</strong> population rema<strong>in</strong>s low (around 4% of the overall population). However, one<br />

must bear <strong>in</strong> m<strong>in</strong>d that cost breakdown between apherese plasma and recovered<br />

plasma rema<strong>in</strong>s very different:<br />

• Costs of Apherese Plasma<br />

• 58% connected <strong>with</strong> collection step<br />

• 42% connected <strong>with</strong> process<strong>in</strong>g, vigilance, and quality-control<br />

• Costs of Recovered Plasma<br />

• 22% connected <strong>with</strong> collection step<br />

• 78% connected <strong>with</strong> process<strong>in</strong>g, vigilance, and quality-control<br />

Hence, th<strong>is</strong> policy will call for specific efforts and rationalization of the collection step<br />

itself as it accounts for the major part of the costs mentioned above. Rationalization can<br />

be understood as a systematic use of accurate processes and techniques, but also a<br />

better use of human resources, as described below.<br />

CLINICAL PRACTICES AND HUMAN RESOURCES<br />

Volume of <strong>in</strong>dividual donations<br />

Across the country, cl<strong>in</strong>ical practices rema<strong>in</strong> uneven, <strong>in</strong> the field of blood and plasma<br />

collection. As a practical matter, the volume of <strong>in</strong>dividual plasma collection may vary<br />

across donation centres and regions. Over the next years, one of the key <strong>is</strong>sues (from a<br />

purely technical po<strong>in</strong>t of view) <strong>is</strong> to make sure that field practices are <strong>in</strong> l<strong>in</strong>e <strong>with</strong> official<br />

requirements set out by the EFS, and to standardize these practices. By do<strong>in</strong>g so, the<br />

volume of <strong>in</strong>dividual collection could be ra<strong>is</strong>ed significantly.<br />

Plasmapherese techniques<br />

Until now, 60% of apherese <strong>is</strong> performed <strong>is</strong> as a simple apherese and 40% <strong>is</strong> performed<br />

<strong>with</strong> an additive solution. Three measures will be implemented over the next years to<br />

maximize and to standardize the rentability of plasmapherese techniques:<br />

• <strong>The</strong> more <strong>in</strong>tensive use of MPC as additive solutions<br />

• <strong>The</strong> automation of the production of the MPC


28 Plasma <strong>KCE</strong> Reports 120<br />

Human resources <strong>is</strong>sues<br />

<strong>The</strong> nurses’ rate of activity <strong>is</strong> also a concern for the EFS: <strong>in</strong> practice, th<strong>is</strong> rate <strong>is</strong><br />

relatively low (<strong>in</strong> average around 55%), due to an <strong>in</strong>accurate d<strong>is</strong>tribution of donation<br />

centres across the country and/or an <strong>in</strong>adequate organization of collection, especially<br />

consider<strong>in</strong>g the <strong>French</strong> sociological profile. In practice the use of donation rooms has<br />

not been rationalized yet, and the total amount of donor accommodation <strong>in</strong> donation<br />

rooms <strong>is</strong> often not fully used.<br />

Pr<strong>in</strong>ciples on cost rationalization<br />

Dec<strong>is</strong>ion makers of the EFS have identified several key measures to improve cost<br />

efficiency of the donation system. All of these measures are not equally profitable for<br />

the donation system, but they all br<strong>in</strong>g a helpful contribution to the smooth runn<strong>in</strong>g of<br />

the whole process and to the best use of donated blood.<br />

<strong>The</strong> follow<strong>in</strong>g measures l<strong>is</strong>ted below have been ranked from the most profitable to the<br />

less profitable (from a cost / efficiency po<strong>in</strong>t of view) consider<strong>in</strong>g today’s workforce.<br />

• Rationaliz<strong>in</strong>g the use of donation rooms and ra<strong>is</strong><strong>in</strong>g the nurses’ rate of<br />

activity: which <strong>in</strong>volves a restructur<strong>in</strong>g of donation facilities and a better<br />

d<strong>is</strong>tribution of donation. Th<strong>is</strong> will automatically ra<strong>is</strong>e the nurses’ rate of<br />

activity<br />

• Implementation of apherese <strong>with</strong> additive solution: th<strong>is</strong> technique will<br />

improve <strong>in</strong>dividual rentability of blood donations<br />

• Unify<strong>in</strong>g and ra<strong>is</strong><strong>in</strong>g the volume of <strong>in</strong>dividual donation<br />

Communication Campaigns: Further Information <strong>in</strong> Appendix “France : Plasma<br />

collection <strong>with</strong><strong>in</strong> the framework of EFS”<br />

Key po<strong>in</strong>ts<br />

• <strong>The</strong> <strong>French</strong> system comb<strong>in</strong>es public law and private law rules <strong>in</strong> the field of<br />

collection, fractionation and supply. Plasma collection <strong>is</strong> not supported by<br />

public subsidies, and the sale price of plasma <strong>is</strong> fixed by the national health<br />

authorities. Delivery targets of the EFS will be ra<strong>is</strong>ed gradually over the next<br />

years.<br />

• EFS’s communication policy targets students and young adults.<br />

• <strong>The</strong> ma<strong>in</strong> driver for the collection centres <strong>is</strong> to improve HR management, to<br />

<strong>in</strong>crease <strong>in</strong>dividual collection volume, and to realize economies of scale.

2.2 TRANSFORMATION OF PLASMA INTO PLASMA<br />

DERIVATIVES<br />

2.2.1 Quick overview of fractionation process<br />

S<strong>in</strong>ce the early 1940s the method of manufactur<strong>in</strong>g plasma, <strong>in</strong>itially developed by Pr<br />

Edw<strong>in</strong> J. Cohn, has been <strong>in</strong>fluenced by multiple factors, which over the years have<br />

forced the <strong>in</strong>dustry to adapt production <strong>in</strong> such a way that the optimal use of plasma – a<br />

human source - rema<strong>in</strong>s to be the lead<strong>in</strong>g objective. As already mentioned above,<br />

human plasma, <strong>is</strong> a unique biological material. Plasma fractionation, a “crack<strong>in</strong>g” process<br />

(cf. petroleum “crack<strong>in</strong>g”) used to prepare therapeutic prote<strong>in</strong>s, <strong>is</strong> and rema<strong>in</strong>s a<br />

complex process. Human plasma derived prote<strong>in</strong> products have unique character<strong>is</strong>tics<br />

l<strong>in</strong>ked to the orig<strong>in</strong> of the start<strong>in</strong>g raw material. Human plasma exhibits a complex<br />

biochemical nature due to its high prote<strong>in</strong> content, close to 60 g per litre, and to the<br />

diversity of its prote<strong>in</strong> components.<br />

Although the plasma derivatives <strong>in</strong>dustry cont<strong>in</strong>ues to use the Cohn procedure,<br />

developed <strong>in</strong> the early 1940s by Professor E. Cohn, the products now obta<strong>in</strong>ed by th<strong>is</strong><br />

method bear little resemblance to those obta<strong>in</strong>ed dur<strong>in</strong>g the early stages of the plasma<br />

derivatives <strong>in</strong>dustry. <strong>The</strong> Cohn procedure cons<strong>is</strong>ts, fundamentally, of the precipitation<br />

of the various prote<strong>in</strong>s by means of changes to pH and salt concentration levels, <strong>with</strong><br />

the prote<strong>in</strong>s be<strong>in</strong>g separated out by centrifugation. In order to prevent the prote<strong>in</strong>s<br />

from be<strong>in</strong>g denatured, the work <strong>is</strong> conducted at low temperatures and ethanol <strong>is</strong> added<br />

at various concentrations. While th<strong>is</strong> <strong>in</strong>itial prote<strong>in</strong> fractionation stage has been<br />

ma<strong>in</strong>ta<strong>in</strong>ed, what has changed <strong>is</strong> the process of purify<strong>in</strong>g the prote<strong>in</strong>s <strong>in</strong> order to obta<strong>in</strong><br />

a safer, purer end product.<br />

Figure 5: Schema of fractionation methods (Source: unpubl<strong>is</strong>hed document<br />

of PPTA – Plasma Prote<strong>in</strong> <strong>The</strong>rapeutics Association)<br />

2.2.1.2 Progress <strong>in</strong> purification<br />

<strong>The</strong> Cohn procedure does not produce therapeutic prote<strong>in</strong>s <strong>in</strong> a pure state, and it has<br />

therefore been necessary to add purification stages which, <strong>in</strong> addition to purify<strong>in</strong>g the<br />

prote<strong>in</strong>s, elim<strong>in</strong>ate the contam<strong>in</strong>ants added dur<strong>in</strong>g fractionation (ethanol and salts).<br />

<strong>The</strong>se purification stages vary depend<strong>in</strong>g on the character<strong>is</strong>tics of the Cohn fraction to<br />

be purified and the nature of the product be<strong>in</strong>g obta<strong>in</strong>ed. In the case of FVIII or antihaemophiliac<br />

factor, the development of aff<strong>in</strong>ity chromatography techniques (whether<br />

us<strong>in</strong>g monoclonal antibodies or hepar<strong>in</strong>) has allowed the development of FVIII <strong>with</strong> far<br />

higher purity levels than the first FVIII used <strong>in</strong> the treatment of haemophilia. Another<br />

significant advantage <strong>is</strong> that the <strong>in</strong>fusion volume of FVIII which now needs to be<br />

adm<strong>in</strong><strong>is</strong>tered <strong>is</strong> considerably lower, <strong>with</strong> result<strong>in</strong>g improvements <strong>in</strong> patient comfort and<br />

quality of life.


<strong>KCE</strong> Reports 120 Plasma 31<br />

Figure 6: Fractionation Techniques and Available Products (Source:<br />

unpubl<strong>is</strong>hed document of PPTA – Plasma Prote<strong>in</strong> <strong>The</strong>rapeutics Association)<br />

Each of the aff<strong>in</strong>ity chromatography systems described above also requires 2 highly<br />

purified, but different, FVIII products. Purification us<strong>in</strong>g monoclonal antibodies (anti-FVIII<br />

antibodies produced <strong>in</strong> mouse cells and bound to the chromatography matrix) allows a<br />

very pure FVIII to be obta<strong>in</strong>ed. In contrast, if aff<strong>in</strong>ity chromatography <strong>with</strong> hepar<strong>in</strong> <strong>is</strong><br />

used, both FVIII and von Willebrand Factor are obta<strong>in</strong>ed. VWF protects the FVIII<br />

molecule and <strong>is</strong> used <strong>in</strong> the treatment of immuno-<strong>in</strong>tolerance <strong>in</strong> haemophiliacs who<br />

have developed anti-Factor VIII antibodies, and can also be used to treat patients <strong>with</strong><br />

von Willebrand Factor deficit.<br />

Immunoglobul<strong>in</strong>s are another group of products where the new purification techniques<br />

have led to unforeseen therapeutic progress. Orig<strong>in</strong>ally, immunoglobul<strong>in</strong>s could only be<br />

adm<strong>in</strong><strong>is</strong>tered <strong>in</strong>tramuscularly, but th<strong>is</strong> method h<strong>in</strong>dered the adm<strong>in</strong><strong>is</strong>tration of sufficient<br />

quantities of immunoglobul<strong>in</strong>s, thereby br<strong>in</strong>g<strong>in</strong>g <strong>in</strong>to question their therapeutic utility.<br />

<strong>The</strong> use of different purification stages – precipitation <strong>with</strong> polyethylene glycol, glyc<strong>in</strong>e<br />

etc. – and different aff<strong>in</strong>ity chromatography systems has made it possible to obta<strong>in</strong><br />

<strong>in</strong>travenous immunoglobul<strong>in</strong>s (IVIG). Th<strong>is</strong> has meant that sufficient therapeutic doses<br />

can be adm<strong>in</strong><strong>is</strong>tered to patients, allow<strong>in</strong>g not just patients <strong>with</strong> primary<br />

immunodeficiency’s to benefit from such treatments (patients suffer<strong>in</strong>g from<br />

immunoglobul<strong>in</strong> production deficit), but also other patients <strong>with</strong> auto-immune illnesses,<br />

together <strong>with</strong> some who have neurological d<strong>is</strong>eases.<br />

2.2.1.3 Progress <strong>in</strong> safety<br />

Because the plasma fractionation <strong>in</strong>dustry uses plasma as its raw material, many viral<br />

illnesses carried <strong>in</strong> the plasma can be transmitted through transfusions of the end<br />

product. In order to prevent the r<strong>is</strong>k of further viral transm<strong>is</strong>sion, the <strong>in</strong>dustry<br />

developed a series of safety procedures which covered the donor, the plasma and the<br />

product. An <strong>in</strong>terest<strong>in</strong>g example <strong>in</strong> the development <strong>in</strong> viral safety can be found <strong>in</strong> the<br />

technical and scientific advances <strong>in</strong> the field of viral DNA detection (NAT techniques)<br />

which complement and improve upon the old viral marker techniques which used ELISA<br />

technology. <strong>The</strong> old techniques were based on detect<strong>in</strong>g antibodies to different viruses.<br />

However, as there <strong>is</strong> a variable time period (known as the ‘w<strong>in</strong>dow period’) between<br />

<strong>in</strong>itial <strong>in</strong>fection and the production of antibodies depend<strong>in</strong>g on the virus type, there <strong>is</strong> a<br />

danger that plasma <strong>with</strong> a low viral load which has tested negative us<strong>in</strong>g ELISA<br />

techniques can still be used <strong>in</strong> plasma fractionation.


32 Plasma <strong>KCE</strong> Reports 120<br />

NAT technology for viral DNA detection has dramatically reduced th<strong>is</strong> w<strong>in</strong>dow period.<br />

Negative results from the subsequent application of NAT technology to the plasma pool<br />

for a range of viruses (HCV, HIV, Parvo B19, HBV, etc.) provide assurance that the<br />

<strong>in</strong>itial viral load <strong>in</strong> the plasma pool <strong>is</strong> zero or very low.<br />

2.2.2 <strong>The</strong> worldwide supply of plasma products<br />

2.2.2.1 Corporate structure of the market of plasma products<br />

Restructur<strong>in</strong>g of the sector of plasma products<br />

Consider<strong>in</strong>g the <strong>in</strong>creas<strong>in</strong>g and vital needs of plasma products <strong>in</strong> most western<br />

countries, and simultaneously the uncerta<strong>in</strong> level of donation, purchasers of plasma<br />

products – ie hospitals, and more generally health care <strong>in</strong>stitutions – can feel <strong>in</strong> an<br />

<strong>in</strong>ferior position towards the plasma fractionation <strong>in</strong>dustry.<br />

<strong>The</strong> evolution of medical practices and also the political pressure of patient associations<br />

on health authorities do not leave them much room for manoeuvre. <strong>The</strong>refore it <strong>is</strong><br />

important to analyze the recent evolution of th<strong>is</strong> <strong>in</strong>dustry to have a clear idea on the<br />

purchasers’ actual negotiation power.<br />

MAIN SPECIFICITIES OF THIS INDUSTRY SINCE THE NINETIES: FUSIONS AND MARKET<br />

CONSOLIDATION<br />

In 1996, the number of global stakeholders <strong>in</strong> the n<strong>in</strong>eties was relatively high: almost 40<br />

companies (or non profit organ<strong>is</strong>ations) were identified worldwide <strong>in</strong> the plasma<br />

fractionation <strong>in</strong>dustry. Follow<strong>in</strong>g several merger waves, only 20 companies still ex<strong>is</strong>t<br />

today.<br />

Among these 20 companies some of them do not play a noticeable role on the global<br />

market because of their size or because of regulatory barriers that still <strong>is</strong>olate their<br />

domestic market from the <strong>in</strong>ternational market. Hence, only a very small number of<br />

companies can be considered as real “global players” <strong>in</strong> terms of economic weight: and<br />

market share.<br />

CURRENT SITUATION (2003-2005)<br />

Worldwide, only five private companies still play an important role (>5%) on the global<br />

market. Non profit organizations are also important stakeholders; however some of<br />

them enjoy a monopoly, based on a specific national regulation.<br />

Leav<strong>in</strong>g aside non profit or public organ<strong>is</strong>ations (the strategy of which <strong>is</strong> largely<br />

connected <strong>with</strong> specific national regulations), private companies’ strategies <strong>is</strong> obviously<br />

guided by f<strong>in</strong>ancial prospects and expected profits on each geographical area. In that<br />

respect, the North-American area rema<strong>in</strong>s the most attractive geographical area for<br />

plasma fractionation firms.<br />

<strong>The</strong>refore, European buyers are apt to compete <strong>with</strong> American ones, and a harsh<br />

competition could ar<strong>is</strong>e at any time between them <strong>with</strong> two possible consequences:<br />

punctual supply shortage and/or sharp <strong>in</strong>crease <strong>in</strong> the prices of plasma-derived products.<br />

Capital structure: Four profiles identified<br />

As far as capital structure <strong>is</strong> concerned, one must notice that four profiles of capital<br />

structure have emerged, generally due to specific and deliberate corporate strategies. In<br />

other cases, (public <strong>in</strong>stitutions or other structures comm<strong>is</strong>sioned by public authorities)<br />

capital structure <strong>is</strong> closely connected <strong>with</strong> the monopoly status of the <strong>in</strong>stitution or<br />

specific national regulations.<br />

PROFILE 1: PRIVATE OWNED FIRMS (OCTAPHARMA AND GRIFOLS)<br />

<strong>The</strong>se two firms are relatively close situations from th<strong>is</strong> po<strong>in</strong>t of view: Octapharma <strong>is</strong> as<br />

a private-owned firm, and so <strong>is</strong> Grifols. In both cases, other stakeholders (especially<br />

banks) can play an important role <strong>in</strong> capital structure. However, private and family<br />

stakeholders rema<strong>in</strong> the key <strong>in</strong>vestors <strong>in</strong> both cases and key stakeholders often rema<strong>in</strong><br />

deeply connected <strong>with</strong> the national or even regional economy (Switzerland / Catalonia).<br />

PROFILE 2: NATIONAL STATE-CONTROLLED FIRMS OR INSTITUTIONS (LFB)<br />

In several western countries, fractionation firms enjoy a monopoly as def<strong>in</strong>ed by a<br />

specific regulation (generally for h<strong>is</strong>torical or cultural reasons). In th<strong>is</strong> case, the firm <strong>is</strong><br />

either owned or controlled by public stakeholders, ie governmental <strong>in</strong>stitutions or<br />

<strong>in</strong>stitutions comm<strong>is</strong>sioned by the government.<br />

LFB <strong>in</strong> France <strong>is</strong> a traditional example: it enjoys a monopoly <strong>in</strong> plasma fractionation<br />

based on a <strong>French</strong> specific regulation. Before 2005, LFB used to be a public-law<br />

<strong>in</strong>stitution. S<strong>in</strong>ce then, it has been transformed <strong>in</strong>to a private law hold<strong>in</strong>g company<br />

(legally a Ltd company) divided <strong>in</strong>to two subsidiary companies: one focus<strong>in</strong>g on<br />

Biotechnology, one focus<strong>in</strong>g on Plasma fractionation. <strong>The</strong> capital of both subsidiary<br />

companies <strong>is</strong> state-controlled. Key members of the Board of Adm<strong>in</strong><strong>is</strong>tration are<br />

government’s representatives (M<strong>in</strong><strong>is</strong>try of F<strong>in</strong>ance, M<strong>in</strong><strong>is</strong>try of Health).<br />

PROFILE 3: FOREIGN-OWNED FIRMS (CSL-BEHRING)<br />

CSL-Behr<strong>in</strong>g <strong>is</strong> a very specific case: it was orig<strong>in</strong>ally a German firm, CSL Behr<strong>in</strong>g became<br />

a subsidiary of CSL Limited, a biopharmaceutical company headquartered <strong>in</strong> Melbourne,<br />

Australia. From a f<strong>in</strong>ancial po<strong>in</strong>t of view, about 90% of the shares are now controlled by<br />

Australian stakeholders. <strong>The</strong>refore, even if CSL-Behr<strong>in</strong>g’s ma<strong>in</strong> facilities and RD centres<br />

are still located <strong>in</strong> Europe, it <strong>is</strong> under the control of foreign-based <strong>in</strong>stitutions.


34 Plasma <strong>KCE</strong> Reports 120<br />

PROFILE 4: TRADITIONAL PRIVATE FIRMS (US FIRMS: BAXTER, TALECRIS)<br />

<strong>The</strong>se firms’ capital structure <strong>is</strong> more traditional, as their capital <strong>is</strong> owned by private<br />

stakeholders (eg: Telecr<strong>is</strong> <strong>is</strong> owned by private equity groups Cerberus Partners and<br />

Ampersand Ventures).<br />

In may 2009, CSL tried to take over the US firm Talecr<strong>is</strong> mentioned above. However,<br />

the US Federal Trade Comm<strong>is</strong>sion recommended legal actions to block the purchase of<br />

Talecr<strong>is</strong> by CSL, on antitrust grounds. US public authorities, especially the new<br />

American adm<strong>in</strong><strong>is</strong>tration, seems to keep a vigilant eye on th<strong>is</strong> <strong>in</strong>dustry, especially on<br />

merg<strong>in</strong>g of bus<strong>in</strong>ess, whenever it <strong>is</strong> apt to have an impact on the American<br />

Ma<strong>in</strong> learn<strong>in</strong>gs for dec<strong>is</strong>ion-makers:<br />

• <strong>The</strong> capital ownership of the lead<strong>in</strong>g global firms of the plasma<br />

fractionation <strong>in</strong>dustry <strong>is</strong> unlikely to evolve over the next years and th<strong>is</strong><br />

<strong>in</strong>dustry, <strong>in</strong> today’s form, seems to be blocked.<br />

• Restructur<strong>in</strong>g of the plasma fractionation <strong>in</strong>dustry: the recent merg<strong>in</strong>g of<br />

bus<strong>in</strong>esses and the <strong>in</strong>creas<strong>in</strong>g weight of each firm (considered <strong>in</strong>dividually)<br />

can be seen as a rather negative evolution for the purchasers’ negotiation<br />

power.<br />

Key po<strong>in</strong>ts<br />

• <strong>The</strong> recent merg<strong>in</strong>g of bus<strong>in</strong>esses has <strong>in</strong>volved a high concentration of<br />

fractionation activities. Given th<strong>is</strong> context, the negotiation power of<br />

purchasers (d<strong>is</strong>regard<strong>in</strong>g public or private status) <strong>is</strong> gett<strong>in</strong>g weaker.<br />

• In the context of a global fractionation <strong>in</strong>dustry, any change <strong>in</strong> the<br />

prescription habits or authorization of drugs of one country <strong>is</strong> apt to have an<br />

impact on the production flows of any other country. Great attention must<br />

be paid to the US policy on that po<strong>in</strong>t.<br />

2.2.3 <strong>The</strong> supply of plasma stable derivatives <strong>in</strong> Belgium<br />

2.2.3.1 Who are the suppliers<br />

<strong>The</strong> plasma collected by the Belgian Red Cross Blood Services - source plasma (SP) as<br />

well as recovered plasma (RP) - <strong>is</strong> sent to CAF-DCF for fractionation b . CAF-DCF <strong>is</strong> the<br />

exclusive manufacturer of plasma derivatives based on plasma collected <strong>in</strong> Belgium. All<br />

locally produced derivatives are <strong>in</strong>tended to be used <strong>with</strong><strong>in</strong> the country. <strong>The</strong> CAF-DCF<br />

was h<strong>is</strong>torically an <strong>in</strong>tegral part of the Belgian Red Cross up to the 23 December 1997.<br />

From that date, the <strong>in</strong>dependent CAF-DCF was set up as a cooperative company <strong>with</strong><br />

limited liability. Today the owners of the shares are:<br />

• the Sanqu<strong>in</strong> Bloodsupply Foundation (Nl) 50.02%,<br />

• the Laboratoire frança<strong>is</strong> du fractionnement et des biotechnologies, LFB<br />

(Fr), a limited company created <strong>in</strong> July 2005 and fully owned by the <strong>French</strong><br />

State 24.99% and<br />

• the Belgian Red Cross 24.99%.<br />

Besides that, CAF-DCF has signed a cooperation contract <strong>with</strong> the German company<br />

Biotest for the fractionation of <strong>in</strong>termediate plasma products <strong>in</strong>to immunoglobul<strong>in</strong>s.<br />

CAF-DCF also fractionates for <strong>in</strong>ternational firms, its total fractionation capacity <strong>is</strong><br />

centered between 500.000 and 550.000 kilo of plasma<br />

b Except for a limited amount that <strong>is</strong> transformed <strong>in</strong>to fresh frozen plasma, used to treat specific<br />

hemorrhagic situations and some coagulation d<strong>is</strong>orders


<strong>KCE</strong> Reports 120 Plasma 35<br />

It <strong>is</strong> surpr<strong>is</strong><strong>in</strong>g to f<strong>in</strong>d that the capital of the company <strong>with</strong> a monopoly on the<br />

fractionation of plasma collected <strong>in</strong> Belgium <strong>is</strong> ma<strong>in</strong>ly <strong>in</strong> the hands of foreign partners.<br />

Grant<strong>in</strong>g a monopoly to an enterpr<strong>is</strong>e only makes sense if, <strong>in</strong> exchange for th<strong>is</strong><br />

monopoly, the enterpr<strong>is</strong>e <strong>in</strong> question fulfils a m<strong>is</strong>sion of collective <strong>in</strong>terest, and if the<br />

authority that granted th<strong>is</strong> monopoly can control what use <strong>is</strong> made of it. In th<strong>is</strong><br />

particular case, control of the CAF-DCF by the public authorities <strong>is</strong> difficult, verg<strong>in</strong>g on<br />

the impossible, given the m<strong>in</strong>ority stake held by the Belgian partner. In addition, it seems<br />

that there <strong>is</strong> no agreement or norm b<strong>in</strong>d<strong>in</strong>g the CAF-DCF <strong>in</strong> terms of the organ<strong>is</strong>ation<br />

and <strong>in</strong>tended use of its output.<br />

It should also be noted that the Board of Adm<strong>in</strong><strong>is</strong>tration of CAF-DCF cons<strong>is</strong>ts as well of<br />

suppliers (CR) as clients (e.g. Sanqu<strong>in</strong>), hav<strong>in</strong>g diverg<strong>in</strong>g <strong>in</strong>terests.<br />

2.2.3.2 Quantities fractionated by CAF-DCF<br />

CAF-DCF <strong>report</strong>ed a quite strait competition on the Belgian market and the underly<strong>in</strong>g<br />

reduction of plasma collection to expla<strong>in</strong> the constant reduction of fractionated plasma.<br />

It must be noted that, overall, CAF-DCF fractionates a smaller volume than the actually<br />

purchased volume. Strategic stocks are then constituted, which can prove helpful<br />

whenever quantities of collected plasma are not sufficient to fulfill the demand. In 2003,<br />

2006 and 2007, we observe that stocks had to be tapped. Th<strong>is</strong> tapp<strong>in</strong>g of the stock <strong>is</strong><br />

confirmed by the audit <strong>report</strong>s of Verhaegen 9 and PWC 15 .<br />

Availability of strategic stocks at the end of each year have been communicated by CAF-<br />

DCF and recorded on the first l<strong>in</strong>e of the table below. If we add to the yearly recorded<br />

strategic stock, the volume of plasma bought to the Red Cross the follow<strong>in</strong>g year - but<br />

not fractionated, and if we subtract the strategic stock recorded at the end of the<br />

follow<strong>in</strong>g year, we calculate a yearly balance, shown on the last l<strong>in</strong>e of the table below.<br />

Calculated by <strong>KCE</strong> and based on CAF-DCF data<br />

Accord<strong>in</strong>g to CAF-DCF, it <strong>is</strong> normal that the yearly variations <strong>in</strong> the volume of the<br />

strategic stock do not correspond to the differences between the volume of purchased<br />

plasma and the one of fractionated plasma. Indeed, losses may occur along the process<br />

e.g. when test<strong>in</strong>g reveals that a batch of plasma <strong>is</strong> <strong>in</strong>fected, as well as production losses -<br />

or even volumes of plasma put <strong>in</strong>to quarant<strong>in</strong>e for test<strong>in</strong>g purposes, and thus not<br />

recorded onto the strategic stock. However the volume of « lost » quantities may<br />

greatly vary from a year to another. No prec<strong>is</strong>e element could be collected concern<strong>in</strong>g<br />

the orig<strong>in</strong> of these variations.

<strong>The</strong> first f<strong>in</strong>d<strong>in</strong>g <strong>is</strong> the bear<strong>is</strong>h trend for the sale of specific derivatives. <strong>The</strong> r<strong>is</strong>k of (and<br />

variations <strong>in</strong> the amounts of derivatives sold. For <strong>in</strong>stance, the r<strong>is</strong>k for Creutzfeld Jacob<br />

or other transm<strong>is</strong>sible d<strong>is</strong>ease has contributed the <strong>in</strong>creas<strong>in</strong>g use of recomb<strong>in</strong>ant<br />

coagulation factors to treat hemophilia, and subsequent decreas<strong>in</strong>g use of plasma<br />

derived factors. Indeed <strong>in</strong> 2004, the Belgian authorities have <strong>report</strong>ed that Belgian<br />

hemophilic patients had received coagulation factors prepared from a European plasma<br />

album<strong>in</strong> per year could have been produced, technically speak<strong>in</strong>g. However, l<strong>in</strong>e 3 of<br />

table 14 shows that no purchasers could be found for such volumes on the Belgian<br />

market. Hence, CAF-DCF had no <strong>in</strong>terest to produce more album<strong>in</strong>s. <strong>The</strong> production<br />

of album<strong>in</strong> follows the demand on the Belgian market. <strong>The</strong> real yield for fractionation of<br />

album<strong>in</strong>s ivaries between 24,6 and 25,6 gram per kilo of plasma.<br />

<strong>in</strong> Belgium <strong>in</strong> gr<br />

Th<strong>is</strong> Belgian demand <strong>is</strong> function of the nature of the competition between firms present<br />

on the market and of an <strong>in</strong>ternational underly<strong>in</strong>g reduction of album<strong>in</strong> demand. Th<strong>is</strong> <strong>is</strong><br />

confirmed by a recent Australian Report of CSL where we can read that ‘In Australia<br />

the amount of album<strong>in</strong> <strong>is</strong>sued per annum over the period 1994-95 to 2004-5 has<br />

<strong>in</strong>creased by an average annual growth rate of ca. 1.4%, as shown <strong>in</strong>, although <strong>in</strong> the last<br />

five years th<strong>is</strong> value has been higher at ca. 2.3%. In contrast, the growth <strong>in</strong> plasma<br />

collections has been ca. 6% per annum over the same period and if all of th<strong>is</strong> plasma had<br />

been converted <strong>in</strong>to product then Australia would have accumulated a substantial<br />

excess of album<strong>in</strong> over requirements. Recogniz<strong>in</strong>g th<strong>is</strong> situation, CSL was <strong>in</strong>structed to<br />

limit the production of album<strong>in</strong> from 1999-00 onward <strong>in</strong> order to balance supply <strong>with</strong><br />

demand. As a consequence of th<strong>is</strong> policy the latest data from 2004-05 <strong>in</strong>dicates that<br />

Australia can meet demand for album<strong>in</strong> by convert<strong>in</strong>g only about 60% of the <strong>available</strong><br />

plasma <strong>in</strong>to f<strong>in</strong><strong>is</strong>hed album<strong>in</strong> product’. 16 <strong>The</strong> same phenomenon occurred <strong>in</strong> Belgium<br />

and a proportion of collected plasma <strong>is</strong> then sold to foreign firms under the form of<br />

<strong>in</strong>termediate products.<br />

<strong>The</strong> case of immunoglobul<strong>in</strong>s<br />

<strong>The</strong> trend identified for IG <strong>is</strong> opposed to the trend for album<strong>in</strong>: it shows that s<strong>in</strong>ce<br />

2004 the quantities of IG sold by the CAF-DCF follow a r<strong>is</strong><strong>in</strong>g path despite the fall <strong>in</strong><br />

collection. Th<strong>is</strong> r<strong>is</strong>e <strong>in</strong> sales volume might be partly expla<strong>in</strong>ed by the desertion of the<br />

Belgian market by one firm around 2004.<br />

<strong>The</strong> calculated ratios present a constant <strong>in</strong>crease s<strong>in</strong>ce 2000. <strong>The</strong>se ratios are calculated<br />

as if all the fractionated plasma was used to produce immunoglobul<strong>in</strong>s. CAF-DCF<br />

<strong>report</strong>ed that the quantities of fractionated plasma used for a given derivative <strong>is</strong> always<br />

determ<strong>in</strong>ed by the demand. <strong>The</strong> <strong>report</strong>ed technical yield by the CAF-DCF <strong>is</strong> 2,7 gr/L<br />

plasma for the period 2000-2002. S<strong>in</strong>ce 2003, the CAF-DCF used a very perform<strong>in</strong>g<br />

technology to produce the Multigam. Dur<strong>in</strong>g the period 2003-2007, the yield was equal<br />

to 4,2 gr/L. In 2008, the use of the nanofiltration caused a light reduction of the yield to<br />

3,9 gr/L. In 2008, the ratio <strong>is</strong> exactly the same as the reference mentioned <strong>in</strong> an<br />

unpubl<strong>is</strong>hed document of PPTA (3.98 g/L). Nevertheless it seems that the world’s best<br />

fractionation operators should obta<strong>in</strong> a constant yield of 5.3 g/L (CSL reference).<br />

However, as we do not have at our d<strong>is</strong>posal the right data to determ<strong>in</strong>e the prec<strong>is</strong>e<br />

content of the yields identified <strong>in</strong> other countries, th<strong>is</strong> compar<strong>is</strong>on must be considered<br />

<strong>with</strong> care.<br />

Th<strong>is</strong> evolution shows CAF-DCF’s responsiveness to demand and also its capacity to<br />

ra<strong>is</strong>e its production at a faster pace than the one of demand.

Key po<strong>in</strong>ts<br />

• <strong>The</strong> production of plasma derivatives <strong>is</strong> not carried out only by the CAF-<br />

DCF, which has concluded agreements <strong>with</strong> foreign firms to carry out a part<br />

of the process<br />

• Relatively large volumes of plasma purchased by CAF-DCF do not<br />

contribute at all to the fractionation process. <strong>The</strong>se volumes seem to vary<br />

greatly over the years, and th<strong>is</strong> phenomenon has not been clarified.<br />

• <strong>The</strong> CAF-DCF seems to experience overcapacity for specific stable<br />

derivatives. In spite of the decrease of the volumes of purchased plasma, it<br />

produces more than it actually sells on the Belgian market. A proportion of<br />

collected plasma (under the form of <strong>in</strong>termediate product) <strong>is</strong> sometimes<br />

dedicated to the production for foreign markets.<br />

• Trad<strong>in</strong>g as well as production agreements, concluded between CAF-DCF<br />

partners, are not transparent towards the public authority, although th<strong>is</strong><br />

f<strong>in</strong>ancially supports CAF-DCF through subsidized plasma prices.<br />

2.2.3.4 Position of CAF-DCF on the <strong>in</strong>ternational market<br />

<strong>The</strong> <strong>in</strong>vestments made by the CAF-DCF, notably <strong>in</strong> a new build<strong>in</strong>g <strong>in</strong> Neder-Over-<br />

Hembeek, enable the company to manufacture quality products that have resulted <strong>in</strong><br />

foreign companies tak<strong>in</strong>g hold<strong>in</strong>gs <strong>in</strong> the capital of the CAF-DCF. Nevertheless, the<br />

CAF-DCF rema<strong>in</strong>s a very small enterpr<strong>is</strong>e on the world stage and its f<strong>in</strong>ancial situation<br />

<strong>is</strong> precarious, despite the <strong>in</strong>direct subsidies it receives through the price that it pays for<br />

plasma to the Red Cross.<br />

An audit carried out <strong>in</strong> 2006 had already highlighted the difficult f<strong>in</strong>ancial situation of the<br />

CAF-DCF. 9 Accord<strong>in</strong>g to th<strong>is</strong> audit, the results of th<strong>is</strong> enterpr<strong>is</strong>e <strong>in</strong> Belgium were <strong>in</strong><br />

the red for the entire period under review (2000 – 2005) and the positive results of<br />

foreign operations were not enough to offset the losses made <strong>in</strong> Belgium. As from<br />

2003, the purchases column saw a substantial <strong>in</strong>crease due to the r<strong>is</strong>e <strong>in</strong> the price of<br />

plasma from plasmapheres<strong>is</strong> (+37%). Two other cost head<strong>in</strong>gs were also to blame for<br />

the deterioration <strong>in</strong> the f<strong>in</strong>ancial situation of the CAF-DCF dur<strong>in</strong>g the period <strong>in</strong><br />

question: ‘special orders’ and ‘purchases of stable derivatives’. <strong>The</strong> r<strong>is</strong>e <strong>in</strong> the head<strong>in</strong>g<br />

‘special orders’ follows the closure of the former CAF fractionation factory <strong>in</strong> Ixelles.<br />

As from 2004, the plasma was fractionated <strong>in</strong>to <strong>in</strong>termediate products <strong>in</strong> the factory at<br />

Neder-Over-Heembeek. <strong>The</strong> <strong>in</strong>termediate products are then sent to foreign partners<br />

for f<strong>in</strong>er fractionation. S<strong>in</strong>ce 2002 the preparation of factor VIII has been carried out by<br />

the <strong>French</strong> company LFB. S<strong>in</strong>ce 2003 the album<strong>in</strong> has been produced by Sanqu<strong>in</strong> <strong>in</strong> the<br />

Netherlands. As for the r<strong>is</strong>e <strong>in</strong> the head<strong>in</strong>g ‘purchases of stable derivatives’, it results<br />

from a comb<strong>in</strong>ation of two factors: the purchase of PPSB by Sanqu<strong>in</strong> follow<strong>in</strong>g the r<strong>is</strong>e<br />

<strong>in</strong> demand for th<strong>is</strong> product and the manufacture of Multigam (immunoglobul<strong>in</strong>s) by the<br />

firm Biotest, which receives the <strong>in</strong>termediate products from the CAF-DCF and sends<br />

them back as the f<strong>in</strong><strong>is</strong>hed product.<br />

Accord<strong>in</strong>g to the audit conducted by F. Verhaegen, th<strong>is</strong> negative f<strong>in</strong>ancial situation<br />

should improve significantly <strong>with</strong> the removal of the compulsory levy on the<br />

pharmaceutical firms.<br />

Key po<strong>in</strong>ts<br />

• <strong>The</strong> CAF-DCF <strong>is</strong> a high technology firm but rather small on the world-wide<br />

scale.<br />

• <strong>The</strong> f<strong>in</strong>ancial situation of the CAF-DCF, structurally negative between 2000<br />

and 2005, recovered thanks to the removal of the levy on pharmaceutical<br />

products, from which plasma derivatives are currently exempt

2.3 LIMITATIONS<br />

<strong>The</strong> subject we are deal<strong>in</strong>g <strong>with</strong> <strong>is</strong> sensitive <strong>in</strong> more than one respect. Firstly, the<br />

products <strong>in</strong> question constitute, for a number of medical conditions, the only possible<br />

therapy at the present time. In addition, the data concern<strong>in</strong>g the price and the quantities<br />

collected and produced concern actors that play an important role <strong>in</strong> th<strong>is</strong> sector. It <strong>is</strong><br />

therefore essential to have validated data <strong>in</strong> order to be able to draw relevant<br />

conclusions. It <strong>is</strong> also essential to identify the reasons why caution <strong>is</strong> necessary <strong>in</strong> the<br />

formulation of certa<strong>in</strong> f<strong>in</strong>d<strong>in</strong>gs and conclusions, and we present here the limitations of<br />

our analys<strong>is</strong>.<br />

<strong>The</strong> first limitation concerns the cost of plasmapheres<strong>is</strong>. We have seen that the<br />

allocation of organ<strong>is</strong>ation costs to th<strong>is</strong> activity, compared <strong>with</strong> the other activities of the<br />

Red Cross, could have a dec<strong>is</strong>ive effect on the real cost of the activity <strong>in</strong> question.<br />

<strong>The</strong> second limitation <strong>is</strong> related to the profitability of plasmapheres<strong>is</strong>. We are not <strong>in</strong> a<br />

position to establ<strong>is</strong>h <strong>with</strong> certa<strong>in</strong>ty the price at which the Red Cross could sell, or could<br />

have sold, plasma on the <strong>in</strong>ternational market. <strong>The</strong> various data collected show that we<br />

cannot be sure of the profitability of such an approach because of the variability of<br />

prices <strong>in</strong> time and space.

3 DEMAND FOR PLASMA DERIVATIVES: THE<br />

CASE OF IMMUNOGLOBULINS<br />

Th<strong>is</strong> chapter aims at describ<strong>in</strong>g the quantities of plasma derivatives used <strong>in</strong> Belgium, how<br />

they are used and what are the future trends <strong>in</strong> consumption. <strong>The</strong> purpose <strong>is</strong> to<br />

subsequently compare quantities used and quantities supplied.<br />

S<strong>in</strong>ce polyvalent immunoglobul<strong>in</strong> (IG) <strong>is</strong> the plasma derivative considered as the market<br />

driver for plasma procurement, we have focused most of our research on IG. 17 In a first<br />

phase, we have studied the <strong>in</strong>dications for IG use: we have compared the<br />

recommendations for IG use <strong>in</strong> Belgium and <strong>in</strong> other <strong>in</strong>dustrialized countries and<br />

reviewed the scientific evidence on IG effectiveness. In a second phase, we have<br />

analyzed the quantities of IG that are used <strong>in</strong> Belgium and <strong>in</strong> other countries, the<br />

amounts that would be required to treat the ma<strong>in</strong> <strong>in</strong>dications and how can IG<br />

consumption be rationalized and reduced.<br />

3.1 USE OF PLASMA DERIVATIVES IN BELGIUM<br />

3.1.1 Methods<br />

3.1.2 Results<br />

We collected data on the use of plasma derivatives <strong>in</strong> Belgium to determ<strong>in</strong>e the<br />

quantities and expenses <strong>in</strong>volved <strong>in</strong> the recent years, as well as to identify recent trends.<br />

<strong>The</strong> National Institute for Health and D<strong>is</strong>ability Insurance (NIHDI or INAMI/RIZIV)<br />

provided us <strong>with</strong> national data on reimbursed plasma derivatives for the period 2004-<br />

2006 <strong>with</strong> the follow<strong>in</strong>g relevant <strong>in</strong>formation: hospital, ward (<strong>in</strong>patient or outpatient),<br />

trimester, category of reimbursement, ATC code 5 (J06BA01 et J06BA02), number of<br />

packages and price. <strong>The</strong>se data have been checked for cons<strong>is</strong>tence between the number<br />

of items and the expenses. <strong>The</strong> yearly quantities of each derivative have been computed<br />

<strong>in</strong> grams or <strong>in</strong>ternational units (IU) by year and by type of producer, categorized <strong>in</strong><br />

CAF-DCF (Centrale Afdel<strong>in</strong>g voor Fractioner<strong>in</strong>g - Département Central de<br />

Fractionnement) or non CAF-DCF.<br />

We had no access to data on non-reimbursed plasma derivatives and derivatives used<br />

for compassionate use.<br />

<strong>The</strong> yearly amounts of the ma<strong>in</strong> reimbursed derivatives are presented <strong>in</strong> Table 17.<br />

Recomb<strong>in</strong>ant coagulation factors, obta<strong>in</strong>ed us<strong>in</strong>g recomb<strong>in</strong>ant DNA technology, are also<br />

mentioned (<strong>in</strong> italic). Though they are not derived from plasma, their evolution<br />

<strong>in</strong>fluences the trends <strong>in</strong> plasma derived factors.<br />

Over the period 2004-2006, the follow<strong>in</strong>g trends <strong>in</strong> consumption are observed: human<br />

factors VIII and IX are decreas<strong>in</strong>g by more than half (-61% and -56% respectively),<br />

parallel to an <strong>in</strong>crease <strong>in</strong> recomb<strong>in</strong>ant factors; von Willebrand factors are doubl<strong>in</strong>g; the<br />

use of FEIBA and sub-cutaneous immunoglobul<strong>in</strong>s are emerg<strong>in</strong>g; and <strong>in</strong>travenous<br />

immunoglobul<strong>in</strong>s have <strong>in</strong>creased by 11%. <strong>The</strong> consumption of CAF-DCF products has<br />

been compared to those from other producers on the Belgian market: all CAF-DCF<br />

products show a sharp decrease <strong>in</strong> quantities, except for immunoglobul<strong>in</strong>s (+18%) and<br />

PPSB (+16%). Th<strong>is</strong> decrease can not be exclusively expla<strong>in</strong>ed by the <strong>in</strong>crease <strong>in</strong><br />

recomb<strong>in</strong>ant product use.

3.1.3 <strong>The</strong> case of immunoglobul<strong>in</strong>s<br />

<strong>The</strong> rema<strong>in</strong><strong>in</strong>g of th<strong>is</strong> chapter focuses on polyvalent immunoglobul<strong>in</strong>s (IG). Demand <strong>in</strong><br />

immunoglobul<strong>in</strong>s <strong>is</strong> the highest among all derivatives when consider<strong>in</strong>g the amount of<br />

plasma required to produce it. Its use cont<strong>in</strong>ues to grow as the number of cl<strong>in</strong>ical<br />

<strong>in</strong>dications for IG keeps <strong>in</strong>creas<strong>in</strong>g. Th<strong>is</strong> <strong>in</strong>creased demand resulted <strong>in</strong> severe product<br />

shortages <strong>in</strong> the late 1990’s <strong>in</strong> the US and a number of other countries, impact<strong>in</strong>g IG<br />

supply <strong>in</strong> Belgium. In addition, IG <strong>is</strong> important <strong>in</strong> terms of amounts <strong>in</strong>volved and budget<br />

impact <strong>in</strong> Belgium, represent<strong>in</strong>g 62% of expenses <strong>in</strong> human plasma derivatives <strong>in</strong> 2006.<br />

In th<strong>is</strong> chapter, IG <strong>is</strong> used to describe pooled polyvalent human immunoglobul<strong>in</strong>, that<br />

can be adm<strong>in</strong><strong>is</strong>tered <strong>in</strong>travenously or subcutaneously; IG does not cover hyperimmune<br />

or specific immunoglobul<strong>in</strong>s.<br />

Polyvalent IG are used to treat a wide range of d<strong>is</strong>eases due to three major therapeutic<br />

properties: IG can replace or supplement antibodies <strong>in</strong> immunodeficiency d<strong>is</strong>eases, <strong>in</strong><br />

order to restore normal humoral immune function; IG has an immunomodulatory<br />

action <strong>in</strong> various autoimmune conditions and <strong>in</strong>flammatory d<strong>is</strong>eases; and IG may be used<br />

as prophylax<strong>is</strong> or therapeutic adjunct aga<strong>in</strong>st some <strong>in</strong>fectious agents <strong>in</strong> patients <strong>with</strong><br />

normal immune humoral function. After IG was shown to be effective <strong>in</strong> the treatment<br />

of auto-immune and <strong>in</strong>flammatory d<strong>is</strong>orders, the l<strong>is</strong>t of d<strong>is</strong>ease for which it <strong>is</strong> used has<br />

grown rapidly.

stand for “authorized <strong>in</strong>dication” or “licensed <strong>in</strong>dication”, which refers to the<br />

<strong>in</strong>dications proposed by the manufacturer and authorized by the drug regulatory<br />

authority.<br />

3.2.1 Recommendations for the use of immunoglobul<strong>in</strong>s<br />

<strong>The</strong> recommendations on which d<strong>is</strong>eases can be treated <strong>with</strong> polyvalent<br />

3.2.1.1<br />

immunoglobul<strong>in</strong>s vary per country, as well as the status of the recommendations.<br />

A few countries have developed full evidence-based guidel<strong>in</strong>es, such as Canada and the<br />

United K<strong>in</strong>gdom (UK), extend<strong>in</strong>g recommendations beyond the labelled <strong>in</strong>dications;<br />

other countries, such as Belgium, did not develop guidel<strong>in</strong>es yet but have legally def<strong>in</strong>ed<br />

a l<strong>is</strong>t of reimbursed <strong>in</strong>dications; for others countries, such as the Netherlands, a l<strong>is</strong>t of<br />

“labelled” <strong>in</strong>dications <strong>is</strong> presented (i.e. <strong>in</strong>dications approved by the regulatory drug<br />

agency). As a consequence, the legal status of these recommendations differs per<br />

country.<br />

Recommendations <strong>in</strong> Belgium<br />

In Belgium, official recommendations for IG use have not been yet publ<strong>is</strong>hed, but<br />

guidel<strong>in</strong>es for IG use are currently under development by the Health Council<br />

(CSS/HGR). <strong>The</strong> only sources for guidance on IG use are the l<strong>is</strong>t of <strong>in</strong>dications that are<br />

authorized <strong>in</strong> Belgium for each IG brand product (labelled <strong>in</strong>dications) and the l<strong>is</strong>t of<br />

reimbursed <strong>in</strong>dications and criteria for reimbursement for each <strong>in</strong>dication, stated <strong>in</strong> the<br />

law (Table 19):<br />

• <strong>The</strong> authorized <strong>in</strong>dications vary per brand product and over time.<br />

• <strong>The</strong> <strong>in</strong>dications and criteria for which IG are reimbursed by the<br />

INAMI/RIZIV are described <strong>in</strong> the Royal Decree from 21 December 2001,<br />

<strong>with</strong> last modification stated <strong>in</strong> the M<strong>in</strong><strong>is</strong>terial Decree from 15 July 2008. d<br />

Intravenous immunoglobul<strong>in</strong>s<br />

In Belgium, several brands or pharmaceutical specialities of <strong>in</strong>travenous immunoglobul<strong>in</strong>s<br />

(IVIG) are reg<strong>is</strong>tered. Though reimbursed <strong>in</strong>dications vary per brand product, the<br />

follow<strong>in</strong>g pathologies are considered <strong>in</strong> the decree and summarized <strong>in</strong> Table 19:<br />

1. Haematological <strong>in</strong>dications<br />

• Primary immune deficiency conditions: agammaglobul<strong>in</strong>emia;<br />

hypogammaglobul<strong>in</strong>emia <strong>with</strong> specific criteria; congenital deficiency <strong>in</strong> antipolysaccharidic<br />

• Secondary immune deficiency:<br />

o Multiple myeloma and chronic lymphocytic leukaemia <strong>with</strong> severe<br />

hypogammaglobul<strong>in</strong>emia and recurrent <strong>in</strong>fections<br />

o Prevention of <strong>in</strong>fections <strong>in</strong> patients hav<strong>in</strong>g an allogenic bone marrow<br />

3.2.1.2 Recommendations <strong>in</strong> other countries<br />

<strong>The</strong> recommendations for IG use <strong>in</strong> terms of which cl<strong>in</strong>ical <strong>in</strong>dications can be treated<br />

<strong>with</strong> IG are presented for five other <strong>in</strong>dustrialized countries and compared to Belgium<br />

<strong>in</strong> Table 20.<br />

In Canada, the UK and Australia, guidel<strong>in</strong>es are clearly stat<strong>in</strong>g that “IG therapy <strong>is</strong> not<br />

<strong>in</strong>dicated” for specific conditions, described as “No” <strong>in</strong> the table, when applicable.<br />

<strong>The</strong> sources of these recommendations on IG use are described below:<br />

1. In Canada, detailed national guidel<strong>in</strong>es cover<strong>in</strong>g the haematological and<br />

neurological <strong>in</strong>dications have been publ<strong>is</strong>hed <strong>in</strong> four articles <strong>in</strong> the journal<br />

Transfusion Medic<strong>in</strong>e Reviews <strong>in</strong> 2007. 18-21 <strong>The</strong>y have been elaborated by a<br />

special committee, based on scientific evidence and us<strong>in</strong>g expert panels.<br />

2. In the United K<strong>in</strong>gdom, evidence-based guidel<strong>in</strong>es from the Department of<br />

Health have been elaborated and the most updated version <strong>is</strong> dated May<br />

2008. 17 Besides a l<strong>is</strong>t of recommendations on IG use, a l<strong>is</strong>t of “grey<br />

<strong>in</strong>dications” has been establ<strong>is</strong>hed: grey <strong>in</strong>dications are those “for which the<br />

evidence base <strong>is</strong> weak, <strong>in</strong> many cases because the d<strong>is</strong>ease <strong>is</strong> rare, and for<br />

which IVIG treatment should be considered on a case by case bas<strong>is</strong>,<br />

priorit<strong>is</strong>ed aga<strong>in</strong>st other compet<strong>in</strong>g demands”. Th<strong>is</strong> comprehensive l<strong>is</strong>t of<br />

grey <strong>in</strong>dications <strong>is</strong> not <strong>in</strong>cluded <strong>in</strong> the table unless the d<strong>is</strong>ease was l<strong>is</strong>ted <strong>in</strong><br />

other country recommendations, and grey <strong>in</strong>dications are <strong>in</strong>dicated <strong>with</strong> a<br />

“(3)”, see Table 3 legend. Th<strong>is</strong> guidel<strong>in</strong>e also <strong>in</strong>cludes a short l<strong>is</strong>t of<br />

<strong>in</strong>dications for which IVIG <strong>is</strong> not recommended (<strong>in</strong>dicated as “No” <strong>in</strong> the<br />

table).<br />

3. In the Netherlands, labelled <strong>in</strong>dications are described <strong>in</strong> a document for<br />

prescribers from the Medic<strong>in</strong>es Evaluation Board (2003). e<br />

4. In France, full recommendations have not been yet establ<strong>is</strong>hed at national<br />

level. Each IG specialty has a limited l<strong>is</strong>t of authorized <strong>in</strong>dications; <strong>in</strong> addition,<br />

a wider l<strong>is</strong>t of d<strong>is</strong>eases for which IG <strong>is</strong> recommended has been publ<strong>is</strong>hed by<br />

the “Comm<strong>is</strong>sion de la Transparence”, “Haute Autorité de Santé” (HAS) for<br />

specific products, and from the Drug Agency (AFSSAPS) for IG <strong>in</strong> general <strong>in</strong><br />

its document «Proposition de hiérarch<strong>is</strong>ation des <strong>in</strong>dications des<br />

Cl<strong>in</strong>ical <strong>in</strong>dications have been categorized per level of priority <strong>in</strong> several<br />

groups, to identify patients that should receive IG <strong>in</strong> a context of shortage.<br />

On one hand, the <strong>in</strong>dications <strong>in</strong>cluded <strong>in</strong> the market<strong>in</strong>g authorizations<br />

(Autor<strong>is</strong>ation de M<strong>is</strong>e sur le Marché or AMM) have been classified <strong>in</strong> priority<br />

groups: priority <strong>in</strong>dications; <strong>in</strong>dications to keep for vital emergencies or after<br />

failure of alternative treatment; and non-priority <strong>in</strong>dications (that can wait till<br />

shortage end). On the other hand, a l<strong>is</strong>t of d<strong>is</strong>eases non <strong>in</strong>cluded <strong>in</strong> the AMM<br />

has been classified <strong>in</strong> 5 groups and publ<strong>is</strong>hed by the AFSSAPS, based on the<br />

expert recommendations. g In total, 8 groups of d<strong>is</strong>eases are def<strong>in</strong>ed, and how<br />

to apply these priority levels <strong>is</strong> not clearly described.<br />

5. In Australia, the “Criteria for the cl<strong>in</strong>ical use of <strong>in</strong>travenous immunoglobul<strong>in</strong><br />

<strong>in</strong> Australia” has been <strong>is</strong>sued by the Australian health M<strong>in</strong><strong>is</strong>ters’ conference <strong>in</strong><br />

December 2007. 22 It <strong>is</strong> <strong>in</strong>tended to be regularly updated, and rev<strong>is</strong>ions are<br />

periodically <strong>is</strong>sued on http://www.nba.gov.au/ivig/pdf/criteria-rev<strong>is</strong>ions.pdf<br />

(last update February 2009). It also set up several groups of d<strong>is</strong>eases for<br />

priority sett<strong>in</strong>g: 1. Conditions for which IVIg has an establ<strong>is</strong>hed therapeutic<br />

role; 2. conditions for which IVIg has an emerg<strong>in</strong>g therapeutic role: 3.<br />

conditions for which IVIg <strong>is</strong> used <strong>in</strong> exceptional circumstances; 4. conditions<br />

for which IVIg use <strong>is</strong> not <strong>in</strong>dicated.<br />

As previously said, the legal status of these recommendations differs per country, due<br />

to the difference between sources describ<strong>in</strong>g them.<br />

Based on the compar<strong>is</strong>on of national recommendations (Table 20), the follow<strong>in</strong>g<br />

conclusions on <strong>in</strong>dication for IG can be drawn:<br />

• IG <strong>is</strong> recommended <strong>in</strong> all countries for a number of d<strong>is</strong>eases, <strong>in</strong> a<br />

cons<strong>is</strong>tent way: primary immune deficiencies, multiple myeloma and<br />

chronic lymphocytic leukaemia for selected situations, idiopathic<br />

thrombocytopenic purpura, Kawasaki d<strong>is</strong>ease and selected neurological<br />

d<strong>is</strong>eases such as Guilla<strong>in</strong> Barré syndrome. It should be noted that the<br />

recommendations publ<strong>is</strong>hed <strong>in</strong> the Netherlands <strong>in</strong>clude only a limited<br />

number of <strong>in</strong>dications because only reimbursed <strong>in</strong>dications are l<strong>is</strong>ted; th<strong>is</strong><br />

does not precludes that IG use <strong>is</strong> accepted for other d<strong>is</strong>eases.<br />

• In many <strong>in</strong>dications, IG <strong>is</strong> only recommended <strong>in</strong> “selected” cases of a<br />

given d<strong>is</strong>ease, accord<strong>in</strong>g to specific criteria described by each country.<br />

Criteria <strong>in</strong>clude cl<strong>in</strong>ical variables, severity or level of d<strong>is</strong>ability, age,<br />

biological criteria (e.g. serum Ig levels) or therapeutic response to other<br />

treatments. For <strong>in</strong>stance, IG <strong>is</strong> only recommended for multiple scleros<strong>is</strong><br />

and dermatomyosit<strong>is</strong> cases show<strong>in</strong>g failure or contra-<strong>in</strong>dications to<br />

standard treatment.<br />

• However for many other d<strong>is</strong>eases, recommendations for the use of IG are<br />

not cons<strong>is</strong>tent across countries. In most of these d<strong>is</strong>eases, the <strong>available</strong><br />

evidence on IG effectiveness <strong>is</strong> either not <strong>available</strong>, of low level,<br />

<strong>in</strong>cons<strong>is</strong>tent across studies, or only show a marg<strong>in</strong>al benefit.<br />

Key po<strong>in</strong>ts<br />

• In these six <strong>in</strong>dustrialized countries, IG <strong>is</strong> recommended for a def<strong>in</strong>ed<br />

number of d<strong>is</strong>eases <strong>in</strong> a cons<strong>is</strong>tent way.<br />

• In many <strong>in</strong>dications, IG <strong>is</strong> only recommended <strong>in</strong> “selected” cases and the<br />

criteria for IG treatment vary per country.<br />

• In a number of d<strong>is</strong>eases, IG <strong>is</strong> not recommended on a cons<strong>is</strong>tent way across<br />

countries. Th<strong>is</strong> mostly concern d<strong>is</strong>eases <strong>with</strong> an auto-immune component,<br />

for which the <strong>available</strong> evidence <strong>is</strong> either of low level or only shows marg<strong>in</strong>al<br />

benefit.<br />

3.2.2 Evidence review on immunoglobul<strong>in</strong> effectiveness<br />

3.2.2.1 Background<br />

3.2.2.2 Methods<br />

<strong>The</strong> mechan<strong>is</strong>ms of action of polyvalent immunoglobul<strong>in</strong>s (IG) are complex and not<br />

totally elucidated today, aside of their use <strong>in</strong> correct<strong>in</strong>g immunodeficiencies. In<br />

immunodeficiency d<strong>is</strong>eases, polyvalent IG <strong>is</strong> given to restore normal humoral immune<br />

function by <strong>in</strong>creas<strong>in</strong>g antibody levels. In autoimmune d<strong>is</strong>orders and some <strong>in</strong>flammatory<br />

d<strong>is</strong>eases, it <strong>is</strong> assumed to have a rapid immunomodulatory action, by neutraliz<strong>in</strong>g<br />

circulat<strong>in</strong>g auto-antibodies, modulat<strong>in</strong>g the production of <strong>in</strong>flammatory cytok<strong>in</strong>es,<br />

<strong>in</strong>terfer<strong>in</strong>g <strong>in</strong> complement activation, and a few other mechan<strong>is</strong>ms. In the long term, it<br />

also regulates the production of antibodies and cytok<strong>in</strong>es. Th<strong>is</strong> evidence review does<br />

not cover the IG mechan<strong>is</strong>ms of action but it reviews the effectiveness of IG <strong>in</strong> treat<strong>in</strong>g<br />

a number of d<strong>is</strong>eases.<br />

Scope<br />

As more than 100 <strong>in</strong>dications have been considered for IG use, th<strong>is</strong> literature review<br />

focuses on the <strong>in</strong>dications that contribute to address the research question. We<br />

selected <strong>in</strong>dications for which IG are reimbursed or recommended by national<br />

authorities and/or likely to consume significant amounts of IG and/or have been covered<br />

<strong>in</strong> systematic reviews. We <strong>in</strong>cluded the follow<strong>in</strong>g d<strong>is</strong>eases (see Table 21):<br />

• <strong>in</strong>dications reimbursed <strong>in</strong> Belgium<br />

• d<strong>is</strong>eases for which IG <strong>is</strong> recommended <strong>in</strong> five comparable <strong>in</strong>dustrialized<br />

countries (France, Netherlands, UK, Canada and Australia)<br />

• other d<strong>is</strong>eases covered by Cochrane systematic reviews <strong>in</strong>clud<strong>in</strong>g IG<br />

effectiveness<br />

• d<strong>is</strong>eases under <strong>in</strong>vestigation that may consume high amounts of IG<br />

Twenty-n<strong>in</strong>e <strong>in</strong>dications have thus been selected for th<strong>is</strong> literature review:<br />

Haematological d<strong>is</strong>eases<br />

1. Primary immune deficiency conditions<br />

2. Secondary immune deficiencies:<br />

• Multiple myeloma and chronic lymphocytic leukaemia<br />

• Allogenic bone marrow or stem cell transplant<br />

• Prophylax<strong>is</strong> <strong>in</strong> solid organ transplant<br />

• Suspected or proven <strong>in</strong>fections <strong>in</strong> neonates<br />

• Preterm and/or low birth weight <strong>in</strong>fants<br />

• Paediatric HIV/AIDS<br />

3. Idiopathic thrombocytopenic purpura<br />

4. Isoimmune haemolytic jaundice <strong>in</strong> neonates<br />

5. Fetal allo-immune thrombocytopenia<br />

Neurological and neuro-muscular d<strong>is</strong>eases<br />

2. Chronic <strong>in</strong>flammatory demyel<strong>in</strong>at<strong>in</strong>g polyradiculoneuropathy<br />

3. Multifocal motor neuropathy<br />

4. Paraprote<strong>in</strong>-associated peripheral neuropathies<br />

5. Multiple scleros<strong>is</strong><br />

6. Lambert-Eaton myasthenic syndrome (LEMS)

Search strategy<br />

<strong>The</strong> search for evidence synthes<strong>is</strong> was focused on systematic reviews. Systematic<br />

reviews identified were subsequently updated <strong>with</strong> orig<strong>in</strong>al RCT publ<strong>is</strong>hed <strong>in</strong> Medl<strong>in</strong>e or<br />

Embase, after the last literature search. For d<strong>is</strong>eases not covered by a systematic<br />

Primary immune deficiencies<br />

Primary immunodeficiency d<strong>is</strong>orders (PID) result from <strong>in</strong>tr<strong>in</strong>sic defects of the immune<br />

system, <strong>in</strong> contrast to immune d<strong>is</strong>orders that are secondary to <strong>in</strong>fection, chemotherapy<br />

or immunosuppressive therapy. Individuals <strong>with</strong> PID are prone to recurrent bacterial<br />

<strong>in</strong>fections, typically <strong>in</strong> respiratory and gastro-<strong>in</strong>test<strong>in</strong>al tracts, or protozoal, fungal and<br />

viral <strong>in</strong>fections, of vary<strong>in</strong>g severity. Deficiencies of various components of the immune<br />

system have been identified, and more than 200 different PID are currently recognized<br />

by the WHO. In Europe, the PID requir<strong>in</strong>g IG replacement that are the most commonly<br />

diagnosed are: the common variable immunodeficiency (CVID) - revealed at adulthood,<br />

<strong>KCE</strong> Reports 120 Plasma 55<br />

• IG reduces the <strong>in</strong>cidence and severity of <strong>in</strong>fection <strong>in</strong> patients <strong>with</strong><br />

agammaglobul<strong>in</strong>emia and severe hypo-gammaglobul<strong>in</strong>emia.<br />

• Effectiveness of IG <strong>in</strong> milder hypogammaglobul<strong>in</strong>emia, IgG subclass<br />

deficiency and impaired polysaccharide responsiveness <strong>is</strong> unclear.<br />

• <strong>The</strong> route of adm<strong>in</strong><strong>is</strong>tration (IV or SC) does not <strong>in</strong>fluence treatment<br />

Secondary immune deficiencies<br />

In many patients, the immune deficiency <strong>is</strong> a direct consequence of a decreased antibody<br />

production due to cancers of the haematopoietic system, such as multiple myeloma or<br />

chronic lymphocytic leukaemia, cytotoxic chemotherapy, immunosuppressive therapy to<br />

prevent transplants rejection, very low weight etc.<br />

<strong>The</strong> effectiveness of IG <strong>in</strong> treat<strong>in</strong>g the conditions lead<strong>in</strong>g to secondary immune<br />

deficiency varies per pathology. It has only been well studied for specific pathologies,<br />

such as multiple myeloma, chronic lymphocytic leukaemia and stem cell transplants (see<br />

below). For hypo-gammaglobul<strong>in</strong>emia related to other d<strong>is</strong>eases or drug therapy, no<br />

evidence on the benefit of IG treatment was found. However, most guidel<strong>in</strong>es<br />

recommend the use of IG – besides antimicrobial prophylax<strong>is</strong> – to decrease the r<strong>is</strong>k of<br />

<strong>in</strong>fection <strong>in</strong> cases <strong>with</strong> the same criteria than those set for PID requir<strong>in</strong>g IG<br />

supplementation: IgG levels under reference range and severe or recurrent bacterial<br />

<strong>in</strong>fections that are unresponsive to prophylactic antibiotics etc. 17, 22 .<br />

Multiple myeloma and chronic lymphocytic leukaemia<br />

Multiple myeloma (MM) and chronic lymphocytic leukaemia (CLL) are rare proliferative<br />

d<strong>is</strong>orders that lead to a higher <strong>in</strong>cidence of serious bacterial <strong>in</strong>fections, such as<br />

pneumonias and ur<strong>in</strong>ary tract <strong>in</strong>fections. Factors underly<strong>in</strong>g the <strong>in</strong>creased susceptibility<br />

to <strong>in</strong>fections are many and complex. A major factor <strong>is</strong> the decreased capacity to<br />

produce potent immunoglobul<strong>in</strong>s, often reflected by a certa<strong>in</strong> degree of hypogammaglobul<strong>in</strong>emia<br />

observed <strong>in</strong> the majority of patients. In MM, the immunodeficiency<br />

<strong>is</strong> ma<strong>in</strong>ly caused by abnormal Ig production and impairment of the primary immune<br />

response. 41 Infections and its consequences (<strong>in</strong>clud<strong>in</strong>g renal failure) are the major cause<br />

of morbidity and mortality <strong>in</strong> both d<strong>is</strong>eases. Up to 65% of CLL patients die from<br />

<strong>in</strong>fection-related events and MM cases have a fatality rate of 30%. Many treatment<br />

strategies ex<strong>is</strong>t for MM and CLL; IG <strong>is</strong> ma<strong>in</strong>ly used as prophylactic agent to prevent<br />

<strong>in</strong>fections, mostly <strong>in</strong> recurrent life threaten<strong>in</strong>g <strong>in</strong>fections. 42<br />

A Cochrane review updated <strong>in</strong> 2009 <strong>in</strong>cluded ten RCT <strong>in</strong>volv<strong>in</strong>g MM or CLL patients<br />

<strong>with</strong> hypogammaglobul<strong>in</strong>emia and recurrent <strong>in</strong>fections, and the meta-analys<strong>is</strong> comb<strong>in</strong>ed<br />

studies from both d<strong>is</strong>eases. 43 It showed that no benefit of IG could be demonstrated <strong>in</strong><br />

terms of mortality, but IG significantly decreased the r<strong>is</strong>k of cl<strong>in</strong>ically documented<br />

<strong>in</strong>fections by 51% (RR 0.49, 95% CI 0.39-0.61), and significantly reduced the occurrence<br />

of microbiologically documented <strong>in</strong>fections as compared to controls (RR 0.71, 95% CI<br />

0.53-0.95). Authors concluded that IG use may be considered <strong>in</strong> MM and CLL patients<br />

<strong>with</strong> hypogammaglobul<strong>in</strong>emia and recurrent <strong>in</strong>fections, for the reduction of cl<strong>in</strong>ically<br />

documented <strong>in</strong>fections.<br />

Another systematic review, conducted by the same group, <strong>in</strong>cluded n<strong>in</strong>e of the 10 RCT<br />

<strong>in</strong>volv<strong>in</strong>g CLL and MM patients, and presented similar f<strong>in</strong>d<strong>in</strong>gs and conclusions. 44<br />

A 2005 systematic review on the cost of d<strong>is</strong>ease <strong>in</strong>cluded cost-effectiveness studies. 45 It<br />

only found one cost effectiveness study on IG, publ<strong>is</strong>hed <strong>in</strong> 1991, thus excluded from<br />

th<strong>is</strong> review. 46<br />

IG significantly decreased documented <strong>in</strong>fections <strong>in</strong> CLL and MM patients but<br />

had no impact on mortality. IG <strong>is</strong> considered <strong>in</strong> patients <strong>with</strong> documented<br />

hypogammaglobul<strong>in</strong>emia and recurrent <strong>in</strong>fections.

Bone marrow transplantation and hematopoietic stem cell transplantation<br />

Bone marrow transplantation (BMT) and hematopoietic stem cell transplantation<br />

(HSCT) comprom<strong>is</strong>e the immune system of patients due to the adm<strong>in</strong><strong>is</strong>tration of high<br />

doses of chemo-radiotherapy prior to <strong>in</strong>fusion of the donor stem cells. 44 Multiple<br />

immunological deficiencies, <strong>in</strong>clud<strong>in</strong>g T- and B-cell abnormalities and<br />

hypogammaglobul<strong>in</strong>emia, pred<strong>is</strong>pose patients to a high r<strong>is</strong>k of develop<strong>in</strong>g <strong>in</strong>fections. As<br />

the <strong>in</strong>cidence of CMV seropositivity <strong>in</strong> the general population <strong>is</strong> high, CMV reactivation<br />

and subsequent d<strong>is</strong>ease becomes a significant prognostic factor of morbidity and<br />

mortality <strong>in</strong> BMT/HSTC. Even though antiviral agents can <strong>in</strong>hibit the viral replication <strong>in</strong><br />

vivo, they have not been able to treat CMV <strong>in</strong>terstitial pneumonia effectively. Th<strong>is</strong><br />

period of immunological <strong>in</strong>competence usually lasts from six to 12 months. <strong>The</strong>se<br />

abnormalities are less prom<strong>in</strong>ent <strong>in</strong> autologous than <strong>in</strong> allogenic transplantations.<br />

Systematic reviews of evidence are contradictory, despite numerous RCT on th<strong>is</strong> area,<br />

as many of them have divergent f<strong>in</strong>d<strong>in</strong>gs.<br />

On one hand, the Cochrane review publ<strong>is</strong>hed <strong>in</strong> 2008 <strong>in</strong>cluded 30 RCT <strong>with</strong> 4223<br />

patients receiv<strong>in</strong>g prophylax<strong>is</strong> after BMT/HSCT. 43 Twenty-one RCT evaluated polyvalent<br />

IG or compared it to CMV hyper-immune IG. <strong>The</strong> analys<strong>is</strong> did not d<strong>is</strong>t<strong>in</strong>gu<strong>is</strong>h between<br />

allogenic or autologous transplantation. When polyvalent IG was compared to control,<br />

there was no difference <strong>in</strong> all-cause mortality. IG significantly reduced the r<strong>is</strong>k for<br />

<strong>in</strong>terstitial pneumonia but <strong>in</strong>creased the r<strong>is</strong>k for veno-occlusive d<strong>is</strong>ease and adverse<br />

events. Th<strong>is</strong> review concluded that rout<strong>in</strong>e prophylax<strong>is</strong> <strong>with</strong> IG <strong>is</strong> not supported by<br />

<strong>available</strong> evidence for these patients.<br />

On the other hand, a meta-analys<strong>is</strong> of 12 RCT <strong>in</strong>volv<strong>in</strong>g 1282 patients was conducted <strong>in</strong><br />

1993 and showed that IG reduced all cause mortality (though <strong>with</strong> borderl<strong>in</strong>e<br />

significance), CMV pneumonia and non-CMV <strong>in</strong>terstitial pneumonia. 47 Three of the trials<br />

were not RCT and the Cochrane review excluded several of them for methodological<br />

reasons; however, th<strong>is</strong> review allocated a quality weight for data analys<strong>is</strong>.<br />

A major limitation of both reviews <strong>is</strong> that the majority of RCTs are old (patients treated<br />

<strong>in</strong> the 80’s and 90’s) while techniques and treatment for patients undergo<strong>in</strong>g<br />

transplantation for haematological malignancies have changed considerably over the last<br />

two decades, such as the use of non-myeloablative treatment. Th<strong>is</strong> may expla<strong>in</strong> the<br />

divergence <strong>in</strong> conclusions between the two meta-analyses. In addition, several RCT<br />

concluded that IG was not found to be beneficial <strong>in</strong> autologous BMT recipients. Despite<br />

the controversy about the benefit of IG <strong>in</strong> HSCT/BMT, th<strong>is</strong> agent <strong>is</strong> still recommended<br />

<strong>in</strong> most transplantation protocols <strong>in</strong> many countries. Some authors suggest that IG<br />

should be reserved for patients who are hypo-gammaglobul<strong>in</strong>aemic after BMT. 48<br />

IG prophylax<strong>is</strong> significantly reduced the r<strong>is</strong>k for <strong>in</strong>terstitial pneumonia after<br />

BMT/HSCT <strong>in</strong> two meta-analyses. IG also significantly reduced the <strong>in</strong>cidence of<br />

CMV pneumonia <strong>in</strong> one meta-analys<strong>is</strong>.

Solid organ transplant<br />

IG may be <strong>in</strong>dicated for two ma<strong>in</strong> problems encountered <strong>in</strong> solid organ transplant<br />

(SOT) recipients:<br />

• On one hand, immunosuppression after SOT <strong>is</strong> associated <strong>with</strong> <strong>in</strong>creased<br />

r<strong>is</strong>k of opportun<strong>is</strong>tic <strong>in</strong>fections, particularly dur<strong>in</strong>g the 6-month posttransplant<br />

period when viral <strong>in</strong>fections are most prevalent. 49<br />

Cytomegalovirus (CMV) <strong>is</strong> a major cause of d<strong>is</strong>ease and death <strong>in</strong> SOT<br />

recipients dur<strong>in</strong>g th<strong>is</strong> period, <strong>with</strong> an overall <strong>in</strong>cidence of 30% to 50%.<br />

CMV also has the propensity to establ<strong>is</strong>h lifelong ’latency’ <strong>in</strong>fection <strong>in</strong> the<br />

host after the <strong>in</strong>itial <strong>in</strong>fection has resolved. <strong>The</strong>refore, SOT recipients may<br />

be <strong>in</strong>fected either by exogenous virus or by reactivation of latent virus if<br />

they were CMV positive pre-transplant. Those at highest r<strong>is</strong>k of<br />

symptomatic CMV d<strong>is</strong>ease are thus CMV sero-negative patients who<br />

receive organs from CMV sero-positive donors, and CMV sero-positive<br />

patients on heavily immunosuppressive regimens. CMV <strong>is</strong> also associated<br />

<strong>with</strong> <strong>in</strong>creased r<strong>is</strong>k of allograft <strong>in</strong>jury and rejection, opportun<strong>is</strong>tic<br />

<strong>in</strong>fections and late onset malignancies. Two ma<strong>in</strong> strategies to prevent<br />

CMV d<strong>is</strong>ease ex<strong>is</strong>t: prophylax<strong>is</strong> of all organ recipients <strong>with</strong> antiviral<br />

medications and/or immunoglobul<strong>in</strong>s called ’pre-emptive therapy’ for highr<strong>is</strong>k<br />

groups, such as patients receiv<strong>in</strong>g anti-lymphocyte antibody<br />

preparations.<br />

• On the other hand, one-third of patients await<strong>in</strong>g renal allograft transplant<br />

have high levels of pre-formed anti-HLA antibodies, and are called highlysensitized<br />

patients. 50, 51 If transplanted, these patients experience an<br />

<strong>in</strong>crease number of rejection ep<strong>is</strong>odes and have poorer graft survival.<br />

Over the past several years, high doses of IG have been used to help<br />

improve transplantation rates <strong>in</strong> th<strong>is</strong> group. 52<br />

A Cochrane review publ<strong>is</strong>hed <strong>in</strong> 2007 <strong>in</strong>cluded 37 RCT on the effectiveness of IG on<br />

CMV r<strong>is</strong>k and d<strong>is</strong>ease. 53 Studies look<strong>in</strong>g at the efficacy of polyvalent IG and CMV<br />

hyperimmune IG were comb<strong>in</strong>ed as no difference between the two groups could be<br />

detected. <strong>The</strong>re was no significant difference <strong>in</strong> the r<strong>is</strong>k for CMV d<strong>is</strong>ease, CMV <strong>in</strong>fection<br />

and all-cause mortality <strong>with</strong> IG compared <strong>with</strong> placebo/no treatment. However, IG<br />

significantly reduced the r<strong>is</strong>k of death from CMV d<strong>is</strong>ease (RR 0.33, 95% CI 0.14-0.80).<br />

Add<strong>in</strong>g IG to antiviral medication did not affect the r<strong>is</strong>k for CMV d<strong>is</strong>ease, CMV <strong>in</strong>fection<br />

or all-cause mortality, compared to antivirals alone. <strong>The</strong> authors concluded that there<br />

are currently no <strong>in</strong>dications for IG <strong>in</strong> the prophylax<strong>is</strong> of CMV d<strong>is</strong>ease <strong>in</strong> SOT recipients,<br />

consider<strong>in</strong>g that the efficacy of several antiviral medications (valganciclovir, ganciclovir,<br />

acyclovir, valganciclovir) have been demonstrated <strong>in</strong> reduc<strong>in</strong>g CMV d<strong>is</strong>ease, CMV<br />

<strong>in</strong>fection, all-cause and CMV related mortality and opportun<strong>is</strong>tic <strong>in</strong>fections.<br />

In highly sensitized patients, no systematic review was found, but three RCT <strong>in</strong>volv<strong>in</strong>g<br />

kidney transplants <strong>in</strong> patients at r<strong>is</strong>k for rejection were retrieved. A first RCT was<br />

conducted <strong>in</strong> 41 patients hav<strong>in</strong>g received a second kidney transplant and treated <strong>with</strong><br />

immunosuppressant. 54 Daily IG was added to the treatment of 21 patients on the first 5<br />

days after transplantation. <strong>The</strong> number of acute rejection ep<strong>is</strong>odes and <strong>in</strong>cidence of<br />

CMV <strong>in</strong>fection were similar but the 5-year survival rate was significantly higher <strong>in</strong> the IG<br />

group compared to the control group. A second RCT, <strong>in</strong>volv<strong>in</strong>g 30 patients <strong>with</strong><br />

confirmed steroid-res<strong>is</strong>tant rejections, compared the effectiveness of IG versus<br />

monoclonal anti-CD3. 55 <strong>The</strong> <strong>in</strong>cidence of rejections after treatment was lower <strong>in</strong> the IG<br />

group compared to the other group but not significantly (46% vs. 75%, p=0.4). Patient<br />

survival rates and graft survival were not significantly different <strong>in</strong> the two groups.

• IG, used alone or <strong>with</strong> antivirals, for the prophylax<strong>is</strong> of CMV d<strong>is</strong>ease <strong>in</strong> SOT<br />

recipients did not decrease the r<strong>is</strong>k of CMV d<strong>is</strong>ease and overall mortality<br />

compared to placebo, or to antivirals alone, <strong>in</strong> a meta-analys<strong>is</strong> of 30 RCT. IG<br />

reduced the r<strong>is</strong>k of death from CMV d<strong>is</strong>ease compared to placebo. Antiviral<br />

medications are effective.<br />

• In highly sensitized patients, three RCT suggested some benefit of IG<br />

treatment after transplant but failed to show a significant reduction of<br />

transplant rejection.<br />

Suspected or proven <strong>in</strong>fection <strong>in</strong> neonates<br />

As endogenous synthes<strong>is</strong> of immunoglobul<strong>in</strong>s does not beg<strong>in</strong> until about 24 weeks after<br />

birth, neonates are at high r<strong>is</strong>k for morbidity and mortality from <strong>in</strong>fections acquired <strong>in</strong><br />

utero, as well as from exposure to <strong>in</strong>fectious sources <strong>in</strong> neonatal <strong>in</strong>tensive care units. 56<br />

Seps<strong>is</strong> <strong>is</strong> an important cause of neonatal death and bra<strong>in</strong> damage. Though effective<br />

antibiotic treatment <strong>is</strong> essential for seps<strong>is</strong>, adjuvant therapies such as IG may offer an<br />

additional strategy. <strong>The</strong> rationale for IG treatment for neonatal <strong>in</strong>fections <strong>is</strong> based on<br />

the evidence that it provides IgG that can b<strong>in</strong>d to cell surface receptors, provide<br />

opsonic activity, activate complement, promote antibody dependent cytotoxicity and<br />

improve neutrophilic chemolum<strong>in</strong>escence.<br />

A Cochrane review publ<strong>is</strong>hed <strong>in</strong> 2004 <strong>in</strong>cluded 9 RCT <strong>in</strong>volv<strong>in</strong>g 553 neonates <strong>with</strong><br />

suspected <strong>in</strong>fection. 57 Six studies <strong>report</strong>ed on mortality and results showed a reduction<br />

<strong>in</strong> mortality follow<strong>in</strong>g IG treatment <strong>in</strong> cases <strong>with</strong> suspected <strong>in</strong>fection of borderl<strong>in</strong>e<br />

stat<strong>is</strong>tical significance. Treatment <strong>with</strong> IG <strong>in</strong> cases of subsequently proven <strong>in</strong>fection did<br />

result <strong>in</strong> a stat<strong>is</strong>tically significant reduction <strong>in</strong> mortality (RR 0.55, 95% CI: 0.31-0.98).<br />

However, the authors po<strong>in</strong>ts that these f<strong>in</strong>d<strong>in</strong>gs are <strong>in</strong> contrast <strong>with</strong> a previous<br />

Cochrane meta-analys<strong>is</strong> (from the same author) that showed the reverse relationship<br />

(significant reduction <strong>in</strong> mortality <strong>in</strong> suspected <strong>in</strong>fections and non significant reduction <strong>in</strong><br />

proven <strong>in</strong>fections). 58 <strong>The</strong> review also mentions that four former meta-analyses showed<br />

stat<strong>is</strong>tically significant reductions <strong>in</strong> mortality follow<strong>in</strong>g IG treatment for neonatal seps<strong>is</strong>,<br />

up to a six-fold decrease (p=0.007) when IG <strong>is</strong> adm<strong>in</strong><strong>is</strong>tered <strong>in</strong> addition to standard<br />

therapies.<br />

IG given to neonates <strong>with</strong> proven <strong>in</strong>fections reduced overall mortality <strong>in</strong> five<br />

meta-analyses. However, the effectiveness of IG to reduce mortality <strong>in</strong><br />

neonates <strong>with</strong> suspected <strong>in</strong>fections was not always significant.<br />

Preterm / low birth weight <strong>in</strong>fants<br />

As maternal transfer of IG to the foetus occurs ma<strong>in</strong>ly after 32 weeks of gestation and<br />

endogenous synthes<strong>is</strong> does not beg<strong>in</strong> until about 24 weeks after birth, the preterm<br />

<strong>in</strong>fant <strong>is</strong> especially vulnerable to <strong>in</strong>fectious sources. 57 Indeed, nosocomial <strong>in</strong>fections<br />

cont<strong>in</strong>ue to be a significant cause of morbidity and mortality among preterm and/or low<br />

birth weight <strong>in</strong>fants. Due to the mechan<strong>is</strong>ms above described, IG was considered to<br />

have the potential of prevent<strong>in</strong>g or alter<strong>in</strong>g the course of nosocomial <strong>in</strong>fections. 59

treatment (e.g. France) and <strong>in</strong> other countries as a second l<strong>in</strong>e or as one<br />

of the treatment options.<br />

• In adults: Adult ITP usually has an <strong>in</strong>sidious onset and <strong>is</strong> typically a chronic<br />

d<strong>is</strong>ease. Its <strong>in</strong>cidence <strong>in</strong>creases <strong>with</strong> age. IG <strong>is</strong> usually recommended <strong>in</strong><br />

cases <strong>with</strong> r<strong>is</strong>k of serious bleed<strong>in</strong>g, as part of a multi-modal therapy.<br />

Other treatments <strong>in</strong>clude <strong>in</strong>travenous steroids, anti-D immune globul<strong>in</strong>,<br />

v<strong>in</strong>cr<strong>is</strong>t<strong>in</strong>e, platelet transfusions and factor VIIa. However,<br />

recommendations for chronic ITP widely vary per guidel<strong>in</strong>e.<br />

A systematic literature review was publ<strong>is</strong>hed <strong>in</strong> 2008 as part of a health technology<br />

assessment undertaken by the Canadian drug agency. 62 It <strong>in</strong>cluded 28 RCT: 15 RCT<br />

among children <strong>with</strong> acute ITP, 4 RCT among children <strong>with</strong> chronic d<strong>is</strong>ease, 7 RCT<br />

among adult ITP and 2 RCT among mixed populations. IG was compared <strong>with</strong> steroids,<br />

anti-D immunoglobul<strong>in</strong>, modified or different doses of IVIG, or close observation. <strong>The</strong><br />

review only <strong>in</strong>cluded Engl<strong>is</strong>h language publications.<br />

• In children: In one trial that compared IG <strong>with</strong> close observation, IG was<br />

associated <strong>with</strong> earlier improvements <strong>in</strong> platelet counts. IG also showed<br />

higher effectiveness compared <strong>with</strong> steroids for early recovery of<br />

thrombocytopenia <strong>in</strong> acute ITP. <strong>The</strong> advantage of IG over anti-D<br />

immunoglobul<strong>in</strong> <strong>is</strong> uncerta<strong>in</strong> due to sparse evidence. <strong>The</strong> optimal dose of<br />

IG has not been establ<strong>is</strong>hed. <strong>The</strong>re was <strong>in</strong>sufficient evidence to determ<strong>in</strong>e<br />

if specific subgroups of children <strong>with</strong> acute ITP may receive preferential<br />

benefit from IG treatment. <strong>The</strong> role of IG <strong>in</strong> chronic childhood ITP could<br />

not be establ<strong>is</strong>hed, because evidence from scant, poorly designed, and<br />

poorly <strong>report</strong>ed RCT could not be synthesized.<br />

• In adults: Two RCT compared IG <strong>with</strong> steroids <strong>in</strong> adults <strong>with</strong> newly<br />

diagnosed ITP: <strong>in</strong> one, no advantage for IG was found; <strong>in</strong> the other study,<br />

IG was more effective than steroids for the short-term improvement of<br />

thrombocytopenia and gave a more rapid and susta<strong>in</strong>ed response. 63 IG<br />

was associated <strong>with</strong> more severe adverse events that prolonged<br />

hospitalization. <strong>The</strong> review concluded that sparse evidence <strong>in</strong>dicates that<br />

IG may be more efficacious than high dose corticosteroids <strong>in</strong> improv<strong>in</strong>g<br />

platelet counts <strong>in</strong> the short term, though its effect on cl<strong>in</strong>ical outcomes<br />

rema<strong>in</strong>s <strong>in</strong>determ<strong>in</strong>ate. Limited evidence could not demonstrate the<br />

superiority of a 2 g/kg dose of IVIG over a 1 g/kg dose; a dose of 1 g/kg,<br />

however, may be better than a dose of 0.5 g/kg. For the long-term<br />

management of adult ITP, data were <strong>in</strong>sufficient and studies were<br />

heterogeneous, prevent<strong>in</strong>g any conclusion on whether IG has an<br />

advantage over other treatments.<br />

A US study compared the cost-effectiveness of IG, anti-D, methylpredn<strong>is</strong>olone and<br />

predn<strong>is</strong>one. 64 <strong>The</strong>rapies <strong>with</strong> IG and methylpredn<strong>is</strong>olone were less effective and more<br />

expensive than anti-D and predn<strong>is</strong>one, respectively. However, th<strong>is</strong> analys<strong>is</strong> has been<br />

debated by many authors, as it <strong>is</strong> based on several questionable assumptions; for<br />

<strong>in</strong>stance, they assumed that all ITP patients received treatment, all children responded<br />

65, 66<br />

to the <strong>in</strong>itial management strategy, and IG <strong>is</strong> not more effective than steroids.<br />

A more recent Ch<strong>in</strong>ese systematic review of studies publ<strong>is</strong>hed between 1990 and 2007<br />

showed that the use of steroids provided additional life years and was more costeffective<br />

compared <strong>with</strong> IG, but that transferability of results to other countries was<br />

low. 62


<strong>KCE</strong> Reports 120 Plasma 61<br />

• In children <strong>with</strong> acute ITP, evidence suggests that IG improves more rapidly<br />

platelet counts than no treatment or steroids. <strong>The</strong> role of IG <strong>in</strong> chronic<br />

• In adult ITP, sparse evidence <strong>in</strong>dicates that IG may be more efficacious than<br />

Fetal/Neonatal allo-immune thrombocytopenia<br />

Fetal or neonatal allo-immune thrombocytopenia (FNAIT) accounts for 27% of cases of<br />

severe foetal and neonatal thrombocytopenia and <strong>is</strong> the most frequent cause of<br />

foetal/neonatal <strong>in</strong>tracranial haemorrhage. 67 FNAIT occurs when the mother produces<br />

antibodies aga<strong>in</strong>st fetal platelet-specific antigens that the foetus has <strong>in</strong>herited from the<br />

father. <strong>The</strong>se antibodies may easily cross the placenta as early as the 14th week of<br />

gestation and cause fetal thrombocytopenia. Transfer of antibodies <strong>in</strong>creases as<br />

gestation progresses, until a maximum level <strong>is</strong> atta<strong>in</strong>ed <strong>in</strong> the late third trimester. Its<br />

<strong>in</strong>cidence <strong>is</strong> estimated to be one <strong>in</strong> 1000-2000 births. <strong>The</strong> recommended antenatal<br />

therapy, aim<strong>in</strong>g at prevent<strong>in</strong>g <strong>in</strong>tracranial haemorrhage, ma<strong>in</strong>ly cons<strong>is</strong>ts of maternal<br />

<strong>in</strong>fusions of IG, <strong>with</strong> or <strong>with</strong>out steroids, or <strong>in</strong>trauter<strong>in</strong>e transfusion of antigen<br />

compatible platelets. 68 Steroids are often used <strong>in</strong> the management of refractory cases.<br />

A Cochrane review publ<strong>is</strong>hed <strong>in</strong> 2005 identified one RCT <strong>in</strong>volv<strong>in</strong>g 54 pregnant women.<br />

However, th<strong>is</strong> trial only compared <strong>in</strong>travenous IG plus steroids <strong>with</strong> <strong>in</strong>travenous IG<br />

alone, thus not cover<strong>in</strong>g the research question. 68 A systematic review publ<strong>is</strong>hed after<br />

the Cochrane search period identified an additional RCT, publ<strong>is</strong>hed <strong>in</strong> 2007, compar<strong>in</strong>g<br />

aga<strong>in</strong> the effectiveness of IG plus predn<strong>is</strong>one to IG alone <strong>in</strong> 73 women. 69 No RCT<br />

compar<strong>in</strong>g IG to placebo has been found, likely because IG <strong>is</strong> currently the first l<strong>in</strong>e<br />

treatment <strong>in</strong> most sett<strong>in</strong>gs. However, 26 observational studies on IG efficacy have<br />

suggested an improvement <strong>in</strong> cl<strong>in</strong>ical outcome and probable reduction <strong>in</strong> r<strong>is</strong>k for<br />

<strong>in</strong>tracranial haemorrhage. Though no meta-analys<strong>is</strong> wad performed and <strong>in</strong> spite of the<br />

drawbacks of observational studies, most of current practice <strong>is</strong> based <strong>in</strong> their f<strong>in</strong>d<strong>in</strong>gs. 68<br />

Though no RCT have been conducted to study the IG effectiveness <strong>in</strong><br />

fetal/feonatal allo-immune thrombocytopenia, data from observational studies<br />

suggested a benefit of IG.<br />

Isoimmune haemolytic jaundice <strong>in</strong> neonates<br />

Both rhesus factor and ABO <strong>in</strong>compatibilities between maternal and fetal or neonatal<br />

cells can result <strong>in</strong> autoimmune haemolytic d<strong>is</strong>ease of the new-born. <strong>The</strong> use of anti-D<br />

prophylax<strong>is</strong> <strong>in</strong> rhesus negative women has led to a marked decl<strong>in</strong>e <strong>in</strong> haemolytic d<strong>is</strong>ease<br />

of the newborn. However, anti-D immunoglobul<strong>in</strong> does not always prevent sensitization<br />

as a high proportion of haemolytic d<strong>is</strong>ease of the newborn <strong>is</strong> caused by antibodies to<br />

antigens other than D. 70 Exchange transfusion and phototherapy have traditionally been<br />

used to treat affected newborn <strong>in</strong>fants. However, exchange transfusion <strong>is</strong> related to<br />

<strong>in</strong>creased mortality and morbidity. New therapies, aim<strong>in</strong>g at reduc<strong>in</strong>g the need for<br />

exchange transfusion, <strong>in</strong>clude IG.<br />

A Cochrane review publ<strong>is</strong>hed <strong>in</strong> 2002 <strong>in</strong>cluded three RCT, <strong>in</strong>volv<strong>in</strong>g 189 term and<br />

preterm <strong>in</strong>fants <strong>with</strong> rhesus and ABO <strong>in</strong>compatibility. <strong>The</strong> use of exchange transfusion<br />

decreased significantly <strong>in</strong> the IG treated group, <strong>with</strong> a lower mean number of exchange<br />

transfusions per <strong>in</strong>fant. None of the studies assessed long term outcomes. Authors<br />

considered that the applicability of the results <strong>is</strong> limited. A more recent systematic<br />

review publ<strong>is</strong>hed <strong>in</strong> 2003 <strong>in</strong>cluded 4 RCT to compare neonatal IG plus phototherapy to<br />

phototherapy alone. 71 It also found that fewer <strong>in</strong>fants <strong>in</strong> the IG group required exchange<br />

transfusion. <strong>The</strong> IG group also required lower duration of phototherapy and shorter<br />

hospital stays than the control group.<br />

In <strong>is</strong>oimmune haemolytic d<strong>is</strong>ease <strong>in</strong> <strong>in</strong>fants, IG reduced the need for exchange<br />

transfusion and phototherapy and lead to shorter hospital stays.

Guilla<strong>in</strong>-Barré syndrome and variants<br />

Guilla<strong>in</strong>-Barré syndrome <strong>is</strong> an acute d<strong>is</strong>ease of the peripheral nerves. It causes the rapid<br />

development of weakness and usually numbness of the limbs and often the facial,<br />

swallow<strong>in</strong>g and breath<strong>in</strong>g muscles. Between 3.5 and 12% patients die of complications<br />

dur<strong>in</strong>g the acute stage. Recovery takes several weeks or months. One year after onset,<br />

12% patients still require aid to walk and 62% still notice its effect on their or their<br />

carers’ lives three to six years later. 72 , 73<br />

A Cochrane review, updated <strong>in</strong> 2004, has shown that plasma exchange significantly<br />

hastens recovery. 74 A Cochrane review on IG, updated <strong>in</strong> 2006, did not f<strong>in</strong>d any trial<br />

compar<strong>in</strong>g IG <strong>with</strong> placebo <strong>in</strong> adults. 73 It <strong>in</strong>cluded 6 RCT compar<strong>in</strong>g IG <strong>with</strong> plasma<br />

exchange. A meta-analys<strong>is</strong> of 5 of these RCT, <strong>in</strong>volv<strong>in</strong>g 536 patients (mostly adults) <strong>with</strong><br />

severe d<strong>is</strong>ease and us<strong>in</strong>g d<strong>is</strong>ability grades, showed that IG started <strong>with</strong><strong>in</strong> two weeks<br />

from onset hastens recovery as much as plasma exchange. Treatment <strong>with</strong> IG was<br />

significantly more likely to be completed than plasma exchange. Giv<strong>in</strong>g IG after plasma<br />

exchange did not confer significant extra benefit. One study showed a trend toward<br />

higher improvement <strong>with</strong> high-dose (2.4g/kg) compared to low-dose IG (1.2g/kg).<br />

Three trials compared IG to supportive care or steroids <strong>in</strong> children, <strong>in</strong>volv<strong>in</strong>g 75<br />

participants. Results suggested that IG hastens recovery compared <strong>with</strong> supportive care,<br />

further analys<strong>is</strong> of raw data a found significant association when us<strong>in</strong>g d<strong>is</strong>ability grade<br />

lacked power. Th<strong>is</strong> suggests that IG hastens recovery <strong>in</strong> children, compared <strong>with</strong><br />

supportive care alone.<br />

A 1999 study compared the cost-effectiveness of plasma exchange and IG <strong>in</strong> the<br />

treatment of Guilla<strong>in</strong> Barré d<strong>is</strong>ease. 75 Trials compar<strong>in</strong>g the effectiveness of plasma<br />

exchange and IG for the treatment of acute Guilla<strong>in</strong>-Barré syndrome showed <strong>in</strong>sufficient<br />

evidence that one therapy was more effective than the other. <strong>The</strong> study determ<strong>in</strong>ed<br />

that plasma exchange was almost $4,000 less costly per patient than IG but that further<br />

research <strong>is</strong> required to determ<strong>in</strong>e the impact of patient and physician preferences. No<br />

recent cost-effectiveness analys<strong>is</strong> has been found.<br />

• In adult Guilla<strong>in</strong> Barré cases, IG hastens recovery as much as plasma<br />

exchange - which has been shown to be more effective than supportive care<br />

alone.<br />

• In paediatric cases, limited evidence suggests that IG hastens recovery<br />

compared to supportive care alone.<br />

Chronic <strong>in</strong>flammatory demyel<strong>in</strong>at<strong>in</strong>g polyradiculoneuropathy<br />

Chronic <strong>in</strong>flammatory demyel<strong>in</strong>at<strong>in</strong>g polyradiculoneuropathy (CIDP) causes progressive<br />

or relaps<strong>in</strong>g weakness and numbness of the limbs, develop<strong>in</strong>g over at least two months.<br />

It may cause prolonged d<strong>is</strong>ability and even death. It <strong>is</strong> often considered to be a chronic<br />

variant of GBS. CIDP can occur at any age, <strong>with</strong> a peak prevalence <strong>in</strong> the sixth and<br />

seventh decade and a lower prevalence among children. 76 Three therapies have<br />

demonstrated beneficial effect <strong>in</strong> RCT: corticosteroids, plasma exchange and IG.<br />

A Cochrane review updated <strong>in</strong> 2009 <strong>in</strong>cluded 7 RCT <strong>with</strong> 287 participants. 76 <strong>The</strong>se<br />

trials were homogeneous and the overall quality was high. In the 5 RCT compar<strong>in</strong>g IG<br />

aga<strong>in</strong>st placebo, a significantly higher proportion of participants improved <strong>in</strong> d<strong>is</strong>ability<br />

<strong>with</strong><strong>in</strong> one month after IG treatment as compared <strong>with</strong> placebo (RR 2.4, 95% CI 1.7-<br />

3.4). One large RCT <strong>in</strong>cluded <strong>in</strong> th<strong>is</strong> review had a long-term follow up and <strong>in</strong>dicated<br />

that IG improves d<strong>is</strong>ability more than placebo over 24 and 48 weeks. 77


<strong>KCE</strong> Reports 120 Plasma 63<br />

Two small trials compared IG <strong>with</strong> predn<strong>is</strong>olone and plasma exchange respectively, and<br />

showed no difference <strong>in</strong> improvement <strong>in</strong> d<strong>is</strong>ability <strong>in</strong> the IG group compared to the<br />

other therapy. <strong>The</strong>re were no stat<strong>is</strong>tically significant differences <strong>in</strong> frequencies of side<br />

effects between the three types of treatment. Based on th<strong>is</strong> evidence, the authors<br />

concluded that IG improves d<strong>is</strong>ability for at least two to six weeks compared <strong>with</strong><br />

placebo, <strong>with</strong> a number needed to treat of 3. S<strong>in</strong>ce IG, plasma exchange and<br />

predn<strong>is</strong>olone seem to be equally effective, it <strong>is</strong> currently uncerta<strong>in</strong> which of these<br />

treatments should be the first choice.<br />

Cost-effectiveness studies compar<strong>in</strong>g the alternative treatments were also retrieved. A<br />

mult<strong>in</strong>ational study (<strong>in</strong>clud<strong>in</strong>g Belgium) aimed at analyz<strong>in</strong>g <strong>in</strong>cremental cost-effectiveness<br />

of IG compared to predn<strong>is</strong>olone to treat CIDP. 78 IG was shown to be substantially<br />

more expensive than predn<strong>is</strong>olone (3754€ over a 6 week period) and did not reduce<br />

d<strong>is</strong>ability substantially compared to predn<strong>is</strong>olone. But IG did result <strong>in</strong> greater<br />

improvement <strong>in</strong> health-related quality of life. <strong>The</strong> probability of IVIG be<strong>in</strong>g cost-effective<br />

<strong>in</strong> compar<strong>is</strong>on <strong>with</strong> predn<strong>is</strong>olone was 50% or above only if one QALY was valued at<br />

over 250,000€. <strong>The</strong> impact of later side-effects of predn<strong>is</strong>olone on long term costs and<br />

quality of life are likely to reduce the cost per QALY of IG treatment.<br />

In patients <strong>with</strong> CIDP, IG improves d<strong>is</strong>ability for at least two to six weeks<br />

compared <strong>with</strong> placebo, but showed no difference <strong>in</strong> effectiveness compared to<br />

plasma exchange and predn<strong>is</strong>olone. Further cost-effectiveness studies are<br />

required.<br />

Multifocal motor neuropathy<br />

Multifocal motor neuropathy (MMN) <strong>is</strong> a rare d<strong>is</strong>ease marked by a slow progression of<br />

motor weakness, often d<strong>is</strong>tal, asymmetric and <strong>in</strong>volv<strong>in</strong>g the forearms, <strong>with</strong>out sensory<br />

impairment. Consensus statements assert that IG <strong>is</strong> the only safe treatment for MMN<br />

patients. Steroids and plasma exchanges are not effective and may even exacerbate the<br />

d<strong>is</strong>ease.<br />

A Cochrane systematic review publ<strong>is</strong>hed <strong>in</strong> 2005 <strong>in</strong>cluded 4 RCT <strong>in</strong>volv<strong>in</strong>g 34 patients. 79<br />

Strength improved <strong>in</strong> 78% of patients treated <strong>with</strong> IG and only 4% of placebo-treated<br />

patients. D<strong>is</strong>ability improved <strong>in</strong> a higher proportion of patients treated <strong>with</strong> IG (78%)<br />

than <strong>with</strong> placebo (14%) but the difference was stat<strong>is</strong>tically not significant. Authors<br />

concluded that limited evidence from RCT shows that IG has a beneficial effect on<br />

strength. IG has been so far the only therapy show<strong>in</strong>g significant improvement <strong>in</strong> MMN.<br />

In patients <strong>with</strong> multifocal motor neuropathy (MMN), IG showed a significant<br />

effect on muscle strength and a non-significant improvement <strong>in</strong> d<strong>is</strong>ability <strong>in</strong><br />

small trials. No other treatment has proven effective for MMN.<br />

Paraprote<strong>in</strong> associated polyneuropathy<br />

<strong>The</strong> paraprote<strong>in</strong> associated polyneuropathy <strong>is</strong> another auto-immune neuropathy <strong>with</strong><br />

demyel<strong>in</strong>ation, characterized by a slow progression and a sensory predom<strong>in</strong>ance.<br />

However, it may produce eventual d<strong>is</strong>abl<strong>in</strong>g motor symptoms. <strong>The</strong> condition <strong>is</strong><br />

associated <strong>with</strong> a monoclonal paraprote<strong>in</strong>, an immunoglobul<strong>in</strong> molecule produced by<br />

bone marrow cells, that <strong>is</strong> present <strong>in</strong> excess and <strong>is</strong> often non-functional. 80 , 81 Th<strong>is</strong><br />

paraprote<strong>in</strong> may belong to one of these three classes: IgG, IgA or IgM.<br />

A Cochrane review on IgG and IgA paraprote<strong>in</strong>emic peripheral neuropathy, publ<strong>is</strong>hed <strong>in</strong><br />

IgM paraprote<strong>in</strong>-associated demyel<strong>in</strong>at<strong>in</strong>g neuropathy. 81 It <strong>in</strong>cluded two RCT compar<strong>in</strong>g<br />

over placebo at four weeks; 82 a small trial of 11 patients showed a modest improvement<br />

<strong>in</strong> strength <strong>in</strong> 18% of patients. 83 As other therapies such as steroids have been shown<br />

beneficial <strong>in</strong> th<strong>is</strong> d<strong>is</strong>ease <strong>in</strong> open trials, some reviews recommend that IG be considered<br />

but not cont<strong>in</strong>ued if acute benefit <strong>is</strong> not observed. 27

treatment of relapses than predn<strong>is</strong>olone alone. 93,94<br />

2. PPMS: A small RCT publ<strong>is</strong>hed after the search period of the two reviews and<br />

<strong>in</strong>volv<strong>in</strong>g 34 patients <strong>with</strong> PPMS showed that IG significantly reduced d<strong>is</strong>ease<br />

progression as measured by cl<strong>in</strong>ical <strong>in</strong>dicators, compared to placebo. 84<br />

3. SPMS: Three RCT, <strong>in</strong>volv<strong>in</strong>g a total of 585 SPMS patients, cons<strong>is</strong>tently<br />

showed no significant effect of IG on d<strong>is</strong>ease progression, relapses or MRI<br />

lesions compared to placebo. 84,95,96, 97 No meta-analys<strong>is</strong> was performed as only<br />

one RCT was <strong>in</strong>cluded <strong>in</strong> the 2008 review (though no exclusion criteria was<br />

stated).<br />

4. Post-partum relapses: <strong>The</strong> r<strong>is</strong>k of MS relapses <strong>is</strong> <strong>in</strong>creased <strong>in</strong> the post-partum<br />

period and the other <strong>available</strong> therapies are not recommended dur<strong>in</strong>g<br />

pregnancy or lactation. Several non-controlled trial or retrospective studies<br />

on IG treatment suggested that the exacerbation rate <strong>in</strong> the treated group


<strong>KCE</strong> Reports 120 Plasma 65<br />

was lower than <strong>in</strong> a reference population. 98, 99 A multi-national RCT <strong>in</strong> 9 EU<br />

countries <strong>in</strong>clud<strong>in</strong>g Belgium, compar<strong>in</strong>g two doses <strong>in</strong> the 6 months postpartum<br />

(but not to placebo), did not show significant differences <strong>in</strong> outcome<br />

between the two doses. 100 Despite the lack of RCT compar<strong>in</strong>g IG to placebo,<br />

many authors conclude that IG can be considered as an optional treatment to<br />

reduce the <strong>in</strong>creased rate of relapses <strong>in</strong> th<strong>is</strong> period, because no alternative<br />

treatment <strong>with</strong> proven efficacy <strong>is</strong> <strong>available</strong>.<br />

5. In patients <strong>with</strong> cl<strong>in</strong>ically <strong>is</strong>olated syndrome: An RCT evaluated the<br />

occurrence of a second attack <strong>in</strong> 91 MS cases after a first neurological event<br />

suggestive of demyel<strong>in</strong>at<strong>in</strong>g d<strong>is</strong>ease. Among patients <strong>in</strong> the IG group, the<br />

<strong>in</strong>cidence of a second attack and d<strong>is</strong>ease activity as measured by bra<strong>in</strong> MRI<br />

significantly reduced compared to placebo. 101<br />

6. Dosage: all RCT but one used a dose rang<strong>in</strong>g 0.15-0.4g/kg monthly. A s<strong>in</strong>gle<br />

study used 2g/kg but did not yield higher efficacy rates. 90 A study compar<strong>in</strong>g<br />

two dose treatment (0.2 and 0.4g/kg/month) for the treatment of RRMS<br />

could not show any significant differences between the effects of the two<br />

doses. 92<br />

A systematic review searched cl<strong>in</strong>ical and cost effectiveness studies on<br />

immunomodulatory drugs for MS, but did not f<strong>in</strong>d any cost-effectiveness study <strong>in</strong>clud<strong>in</strong>g<br />

IG. 102<br />

• In RRMS d<strong>is</strong>ease, IG has shown beneficial effects on d<strong>is</strong>ease progression and<br />

on magnetic resonance imag<strong>in</strong>g (MRI) lesions (moderate). Comb<strong>in</strong>ed to<br />

predn<strong>is</strong>olone, IG was not more effective <strong>in</strong> the treatment of relapses than<br />

predn<strong>is</strong>olone alone (high). <strong>The</strong> ideal dose and the effect on long term<br />

d<strong>is</strong>ability have not been well studied. IG <strong>is</strong> considered as one of the options<br />

for the treatment of RRMS.<br />

• In PPMS patients, IG delayed d<strong>is</strong>ease progression <strong>in</strong> one RCT (moderate).<br />

• In SPMS d<strong>is</strong>ease, IG had no significant effect on d<strong>is</strong>ease progression or MRI<br />

lesions (high).<br />

• IG reduced the <strong>in</strong>creased rate of relapses <strong>in</strong> the post-partum period <strong>in</strong> open<br />

studies and <strong>is</strong> considered as an optional treatment (low).<br />

Lambert-Eaton myasthenic syndrome<br />

Lambert-Eaton myasthenic syndrome or LEMS <strong>is</strong> a rare autoimmune d<strong>is</strong>order of<br />

neuromuscular transm<strong>is</strong>sion, most commonly seen as a paraneoplasic syndrome (60% of<br />

patients). It <strong>is</strong> characterized by proximal muscle weakness, ocular symptoms, bulbar<br />

symptoms and autonomic dysfunction. LEMS often responds to steroids or other<br />

immunosuppressant.<br />

A Cochrane review publ<strong>is</strong>hed <strong>in</strong> 2005 <strong>in</strong>cluded only 1 RCT assess<strong>in</strong>g the use of IG <strong>in</strong><br />

LEMS cases. 103 Significant improvement <strong>in</strong> limb muscle strength, vital capacity and<br />

dr<strong>in</strong>k<strong>in</strong>g time was observed compared to placebo, but was short term and decl<strong>in</strong>ed<br />

after 8 weeks. <strong>The</strong> review concluded that IG can be considered as an alternative<br />

treatment to steroids and immunosupressants for LEMS.<br />

A small RCT showed that IG improved functional capacities and muscle<br />

strength <strong>in</strong> Lambert-Eaton myasthenic syndrome on the short term

Myasthenia grav<strong>is</strong><br />

Myasthenia grav<strong>is</strong> (MG) <strong>is</strong> an autoimmune d<strong>is</strong>ease, characterized by weakness and<br />

fatigability of muscle chang<strong>in</strong>g over shorter or longer periods. Acute exacerbations (or<br />

cr<strong>is</strong><strong>is</strong>) may be life-threaten<strong>in</strong>g because of swallow<strong>in</strong>g difficulties or respiratory failure. 104<br />

Prevalences tend to <strong>in</strong>crease <strong>with</strong> time, partly due to age<strong>in</strong>g of the population comb<strong>in</strong>ed<br />

to higher prevalence <strong>in</strong> the elderly, and better diagnos<strong>is</strong>. 105 Current treatment <strong>in</strong>cludes<br />

antichol<strong>in</strong>esterase drugs, thymectomy, steroids, immunosupressants, plasma exchange<br />

and IVIG.<br />

A Cochrane review updated <strong>in</strong> 2008 <strong>in</strong>cluded 6 RCT. 106 A placebo controlled trial<br />

<strong>in</strong>volv<strong>in</strong>g 51 patients provided evidence for the effectiveness of IG <strong>in</strong> MG worsen<strong>in</strong>g,<br />

while another small study <strong>in</strong>volv<strong>in</strong>g 15 mild or moderate MG cases found no significant<br />

difference <strong>in</strong> efficacy after six weeks compared to placebo. Two studies, one <strong>in</strong>volv<strong>in</strong>g<br />

87 participants <strong>with</strong> exacerbation and another small study <strong>in</strong>volved 12 participants <strong>with</strong><br />

moderate or severe MG, showed no significant difference between IG and plasma<br />

exchange, after two and four weeks respectively. No significant difference <strong>in</strong> the efficacy<br />

of IG and methylpredn<strong>is</strong>olone was shown <strong>in</strong> a study <strong>in</strong>clud<strong>in</strong>g 33 patients <strong>with</strong> moderate<br />

exacerbations. A large RCT showed no significant difference <strong>in</strong> efficacy between two<br />

doses for MG exacerbations (1 and 2g/kg). An open study of 10 severe MG patients<br />

unresponsive to common treatment showed that IG <strong>in</strong>duced and ma<strong>in</strong>ta<strong>in</strong>ed rem<strong>is</strong>sion<br />

<strong>with</strong> spar<strong>in</strong>g of the dose of immunosuppressive treatments. Gajdos et al. concluded that<br />

there <strong>is</strong> no conv<strong>in</strong>c<strong>in</strong>g evidence to support the rout<strong>in</strong>e use of IG as ma<strong>in</strong>tenance<br />

therapy. Several reviews recommend IG for myasthenic cr<strong>is</strong><strong>is</strong> that are unresponsive to<br />

other agents, for severe exacerbations until other immunosuppressive treatments<br />

achieve stabilization, or as an option to stabilize patients before surgery. 107,108 <strong>The</strong> best<br />

IG dose <strong>in</strong> MG rema<strong>in</strong>s unclear, rang<strong>in</strong>g 1-2g/kg.<br />

IG <strong>is</strong> more effective than placebo and as effective as other therapies (plasma<br />

exchange and steroids) for severe MG exacerbation and MG worsen<strong>in</strong>g, but th<strong>is</strong><br />

benefit was not shown <strong>in</strong> mild and moderate d<strong>is</strong>ease. Most RCT studied MG<br />

<strong>with</strong> exacerbations.<br />

Dermatomyosit<strong>is</strong> and polymyosit<strong>is</strong><br />

Dermatomyosit<strong>is</strong> and polymyosit<strong>is</strong> are idiopathic <strong>in</strong>flammatory myopathies,<br />

characterized by chronic <strong>in</strong>flammation of skeletal muscle which can result <strong>in</strong> pers<strong>is</strong>t<strong>in</strong>g<br />

muscle weakness <strong>with</strong> significant d<strong>is</strong>ability. 109 Dermatomyosit<strong>is</strong> also affects the sk<strong>in</strong>,<br />

results <strong>in</strong> sk<strong>in</strong> abnormalities, while polymyosit<strong>is</strong> may have occasional pulmonary<br />

<strong>in</strong>volvement. Both d<strong>is</strong>eases generally responds to steroid or immunosuppressive drugs<br />

but the optimal therapy rema<strong>in</strong>s unclear, and a number of patients are res<strong>is</strong>tant or only<br />

partially responsive to these therapies. 110<br />

A Cochrane review publ<strong>is</strong>hed <strong>in</strong> 2005 <strong>in</strong>cluded one small RCT on IG compared to<br />

placebo, <strong>in</strong>volv<strong>in</strong>g 15 patients <strong>with</strong> dermatomyosit<strong>is</strong>. 109 It showed that IG was<br />

significantly superior to placebo <strong>in</strong> improv<strong>in</strong>g muscle strength, neuromuscular symptoms<br />

and sk<strong>in</strong> rash. 111 Other therapies did not show clear benefit. <strong>The</strong> RCT concluded that<br />

IG <strong>is</strong> an effective second-l<strong>in</strong>e therapy for patients <strong>with</strong> dermatomyosit<strong>is</strong> that<br />

<strong>in</strong>completely respond to steroids and immunosupressants. A non-controlled trial and<br />

several observational studies confirmed the IG benefit <strong>in</strong> dermatomyosit<strong>is</strong> and<br />

polymyosit<strong>is</strong>. 112,113<br />

IG improved symptoms and muscle strength <strong>in</strong> dermatomyosit<strong>is</strong>.<br />

Inclusion body myosit<strong>is</strong><br />

Inclusion body myosit<strong>is</strong> (IBM) <strong>is</strong> the most common <strong>in</strong>flammatory myopathy <strong>in</strong> elderly<br />

patients. It <strong>is</strong> characterized by a slow chronic progressive and pa<strong>in</strong>less asymmetric<br />

weakness, <strong>with</strong> <strong>in</strong>volvement of d<strong>is</strong>tal muscles <strong>with</strong> atrophy. Corticosteroids and<br />

immunosupressants are not successful. Treatment rema<strong>in</strong>s difficult as there <strong>is</strong> no or<br />

very little response to immunotherapy. 108


<strong>KCE</strong> Reports 120 Plasma 67<br />

Three RCT <strong>in</strong>volv<strong>in</strong>g 47 patients showed similar results. 108 A placebo controlled RCT<br />

<strong>in</strong>volv<strong>in</strong>g 19 patients showed an improvement <strong>in</strong> muscle strength <strong>in</strong> the group treated<br />

by IG compared to placebo, but the differences were not stat<strong>is</strong>tically significant, except<br />

for the muscles used for swallow<strong>in</strong>g. 114 A second study showed similar results. 115 A third<br />

study compared IG (2g/kg) added to predn<strong>is</strong>olone to predn<strong>is</strong>olone alone. 116 After 3<br />

months of treatment, there was no significant difference <strong>in</strong> muscle strength between the<br />

two groups. Despite these negative f<strong>in</strong>d<strong>in</strong>gs, many reviews recommend a short course<br />

of IG (2g/kg) as trial because no other treatment <strong>is</strong> effective. 27,107<br />

IG did not improve muscle strength <strong>in</strong> patients <strong>with</strong> <strong>in</strong>clusion body myosit<strong>is</strong><br />

patients but significantly improved swallow<strong>in</strong>g functions <strong>in</strong> one study<br />

Stiff person syndrome<br />

<strong>The</strong> stiff person syndrome <strong>is</strong> a rare d<strong>is</strong>order of the nervous central system<br />

characterized by severe and ep<strong>is</strong>odic muscle rigidity and spasms. <strong>The</strong> cause <strong>is</strong> unknown<br />

but most patients are associated <strong>with</strong> high levels of antibodies directed aga<strong>in</strong>st a specific<br />

enzyme, the glutamic acid decarboxylase, which <strong>is</strong> responsible for the synthes<strong>is</strong> of a<br />

major neurotransmitter (gamma am<strong>in</strong>o butyric acid).<br />

A s<strong>in</strong>gle RCT conducted <strong>in</strong> 1996-99, <strong>in</strong>volv<strong>in</strong>g 16 patients <strong>with</strong> Stiff person syndrome<br />

compar<strong>in</strong>g IG to placebo, showed that IG significantly reduces muscle stiffness and<br />

occurrence of spasms <strong>in</strong> th<strong>is</strong> d<strong>is</strong>ease compared to placebo. 117 <strong>The</strong> duration of the<br />

beneficial effect of IG varied from 6 weeks to one year. Three open studies have<br />

suggested the same effectiveness and improvement <strong>in</strong> quality of life. 118 , 119 , 120 IG <strong>is</strong> now<br />

considered to be the treatment of choice <strong>in</strong> many countries because other therapies<br />

only produce modest improvement <strong>in</strong> symptoms.<br />

IG significantly reduced muscle stiffness and occurrence of spasms <strong>in</strong> Stiff<br />

Neuromyelit<strong>is</strong> optica<br />

Neuromyelit<strong>is</strong> optica <strong>is</strong> a demyel<strong>in</strong>at<strong>in</strong>g d<strong>is</strong>ease of the sp<strong>in</strong>al cord and optic nerves that<br />

manifest by recurrent attacks, and tends to have a poor prognos<strong>is</strong>. <strong>The</strong>re <strong>is</strong> no proven<br />

effective treatment, although relapses are commonly treated <strong>with</strong> steroids; patients <strong>with</strong><br />

recurrent attacks may be managed <strong>with</strong> immunosupressants. 121 IG has been considered<br />

as a possible treatment because the d<strong>is</strong>ease <strong>is</strong> antibody mediated.<br />

<strong>The</strong>re are a few case studies, <strong>in</strong>volv<strong>in</strong>g 1 to 2 cases, suggest<strong>in</strong>g that monthly IG may be<br />

effective <strong>in</strong> prevent<strong>in</strong>g relapses. 121,122 However, no RCT or other observational studies<br />

were found. More recent studies have rather focused on the effectiveness of rituximab,<br />

as it appears to reduce the frequency of attacks, <strong>with</strong> subsequent stabilization or<br />

improvement <strong>in</strong> d<strong>is</strong>ability. 123,124<br />

<strong>The</strong>re <strong>is</strong> no evidence on the effectiveness of IG <strong>in</strong> neuromyelit<strong>is</strong> optica, and<br />

limited evidence suggested the effectiveness of rituximab<br />

3.2.2.5 Evidence on other medical conditions<br />

Kawasaki d<strong>is</strong>ease<br />

<strong>The</strong> Kawasaki syndrome <strong>is</strong> an acute vasculit<strong>is</strong> affect<strong>in</strong>g <strong>in</strong>fants and young children,<br />

<strong>in</strong>volv<strong>in</strong>g the coronary arteries. Its aetiology <strong>is</strong> unknown. <strong>The</strong> ma<strong>in</strong> complications are<br />

coronary artery aneurysms (CAA) that may occur from the second week of illness<br />

dur<strong>in</strong>g the convalescent stage.<br />

A Cochrane review publ<strong>is</strong>hed <strong>in</strong> 2003 <strong>in</strong>cluded 16 RCT <strong>in</strong>volv<strong>in</strong>g children <strong>with</strong> Kawasaki<br />

d<strong>is</strong>ease. 125 Results of the meta-analyses of IG versus placebo showed a stat<strong>is</strong>tically<br />

significant decrease <strong>in</strong> new CAA <strong>in</strong> favour of IG plus salicylate over salicylate alone, <strong>in</strong><br />

favour of a s<strong>in</strong>gle high dose regime over 4 or 5 day low dose regime. <strong>The</strong>re was also a<br />

significant decrease <strong>in</strong> duration of fever and duration of hospitalization <strong>in</strong> cases treated<br />

<strong>with</strong> IG, <strong>with</strong> no stat<strong>is</strong>tically significant <strong>in</strong>crease <strong>in</strong> adverse events.


68 Plasma <strong>KCE</strong> Reports 120<br />

Authors concluded that children fulfill<strong>in</strong>g the diagnostic criteria for Kawasaki d<strong>is</strong>ease<br />

should be treated <strong>with</strong> high dose IG <strong>with</strong><strong>in</strong> 10 days of onset of symptoms. An RCT<br />

publ<strong>is</strong>hed after the Cochrane search period, compar<strong>in</strong>g the effectiveness of IG at<br />

different doses, showed that a lower dose (1g/kg) was as effective as the standard 2g/kg<br />

dose. 126<br />

A Canadian study compared the cost-effectiveness of aspir<strong>in</strong>, low doses of IG<br />

(0.4g/kg/day for 4 days) and high doses of IG (2g/kg s<strong>in</strong>gle dose). 127 It concluded that a<br />

s<strong>in</strong>gle high dose <strong>is</strong> preferred because it results <strong>in</strong> both lower costs and lower rates of<br />

new CAA. A study <strong>in</strong> Japan came to the same conclusion, though it limited the high<br />

dose therapy to patients <strong>with</strong> specific criteria (Harada score). 128<br />

In Kawasaki d<strong>is</strong>ease, IG showed a significant decrease <strong>in</strong> new coronary artery<br />

abnormalities, fever and hospitalization, compared to placebo. A lower dose<br />

(1g/kg) <strong>is</strong> as effective as a high dose (2g/kg). A high s<strong>in</strong>gle dose (2g/kg) <strong>is</strong> more<br />

cost-effective than a lower dose (0.4g/kg/day) for 4 days.<br />

Viral myocardit<strong>is</strong> <strong>in</strong> children and adults<br />

Acute myocardit<strong>is</strong> <strong>is</strong> a d<strong>is</strong>ease that occurs <strong>in</strong> all age groups. In young patients, it <strong>is</strong> the<br />

most common cause of heart failure requir<strong>in</strong>g cardiac transplantation. 129 It <strong>is</strong> presumed<br />

to usually start as a viral <strong>in</strong>fection, although autoimmune and idiopathic forms also<br />

occur. It rema<strong>in</strong>s unclear if the primary problem <strong>is</strong> most the ongo<strong>in</strong>g damage from a<br />

virus, a post <strong>in</strong>fectious <strong>in</strong>flammatory reaction, or a comb<strong>in</strong>ation of both. However,<br />

immunosuppressive therapy was not shown efficacious <strong>in</strong> previous RCT. As IG has both<br />

antiviral and immunomodulatory effects and <strong>is</strong> an important therapy for Kawasaki<br />

d<strong>is</strong>ease, IG has been used <strong>in</strong> children <strong>with</strong> new-onset myocardit<strong>is</strong>.<br />

A Cochrane systematic review publ<strong>is</strong>hed <strong>in</strong> 2005 <strong>in</strong>cluded only one RCT <strong>in</strong>volv<strong>in</strong>g 62<br />

adult patients <strong>with</strong> presumed viral myocardit<strong>is</strong>. 129 Cl<strong>in</strong>ical improvement and <strong>in</strong>cidence of<br />

death were not significantly different <strong>in</strong> patients receiv<strong>in</strong>g IG compared <strong>with</strong> the placebo<br />

group, due to the high rate of spontaneous recovery. <strong>The</strong> favourable prognos<strong>is</strong> <strong>with</strong><br />

conventional therapy may expla<strong>in</strong> the apparent improvement <strong>report</strong>ed <strong>in</strong> uncontrolled<br />

studies. 129 <strong>The</strong>se f<strong>in</strong>d<strong>in</strong>gs contrast <strong>with</strong> case series and a study compar<strong>in</strong>g cases treated<br />

<strong>with</strong> IG to recent h<strong>is</strong>torical controls, which <strong>report</strong>ed significant improvements <strong>in</strong> left<br />

ventricular function <strong>in</strong> cases treated <strong>with</strong> IG. 130,131,132 Authors concluded that evidence<br />

from th<strong>is</strong> trial does not support the use of IG for the management of adults <strong>with</strong><br />

presumed viral myocardit<strong>is</strong>. <strong>The</strong>re are no randomized paediatric trials.<br />

Evidence from one trial did not show a benefit of IG for the management of<br />

presumed viral myocardit<strong>is</strong> <strong>in</strong> adults. <strong>The</strong>re <strong>is</strong> no evidence for paediatric cases.<br />

Treat<strong>in</strong>g seps<strong>is</strong> and septic shock<br />

Despite the development of new antibiotics and advances <strong>in</strong> the management of<br />

critically ill adults <strong>with</strong> severe <strong>in</strong>fections, the mortality rate from septic shock rema<strong>in</strong>s<br />

very high, rang<strong>in</strong>g from 21 to 72%. 133,134 Because of its broad and potent activity aga<strong>in</strong>st<br />

bacterial products and host cytok<strong>in</strong>es, polyclonal <strong>in</strong>travenous immunoglobul<strong>in</strong> has been<br />

<strong>in</strong>vestigated as an adjunctive therapy for treat<strong>in</strong>g severe <strong>in</strong>fections.<br />

Several Cochrane systematic reviews have been publ<strong>is</strong>hed on th<strong>is</strong> topic. <strong>The</strong> most<br />

recent one (2002) <strong>in</strong>cluded 11 RCT <strong>in</strong>volv<strong>in</strong>g 492 patients treated <strong>with</strong> polyvalent IG. 133<br />

Overall mortality was reduced <strong>in</strong> patients who received polyclonal IG compared to<br />

placebo or no <strong>in</strong>tervention (RR=0.64; 95% CI 0.51-0.80). Polyclonal IG also reduced<br />

mortality from septic shock <strong>in</strong> a pooled analys<strong>is</strong> from 3 RCT. Several other systematic<br />

reviews and meta-analyses have been publ<strong>is</strong>hed after th<strong>is</strong> Cochrane review. <strong>The</strong> two<br />

most recent meta-analyses searched literature till March and May 2006 and <strong>in</strong>cluded 14<br />

and 20 RCT respectively, compar<strong>in</strong>g IG for the adjunctive treatment of severe seps<strong>is</strong><br />

and septic shock <strong>with</strong> placebo or no treatment. 134,135 Though only 5 RCT were common<br />

to the three reviews, the two meta-analyses found similar and significant reduction <strong>in</strong><br />

mortality <strong>in</strong> patients treated <strong>with</strong> IG compared to placebo or no <strong>in</strong>tervention (RR=0.66;<br />

95% CI 0.53-0.83 and RR=0.74; 95% CI, 0.62-0.89). 134,135

IG used as an adjuvant therapy <strong>in</strong> patients <strong>with</strong> seps<strong>is</strong> and septic shock reduced<br />

mortality compared <strong>with</strong> placebo or no <strong>in</strong>tervention. Th<strong>is</strong> survival benefit was<br />

cons<strong>is</strong>tently observed <strong>in</strong> three large meta-analyses.<br />

Treat<strong>in</strong>g Respiratory Syncitial Virus <strong>in</strong>fections<br />

Infection <strong>with</strong> the Respiratory Syncitial Virus (RSV) <strong>is</strong> a common cause of childhood<br />

bronchiolit<strong>is</strong> and pneumonia, and can cause severe d<strong>is</strong>ease <strong>in</strong> children between two to<br />

eight months. In older age groups, RSV may cause simple upper respiratory tract illness.<br />

Nearly all children have had at least one <strong>in</strong>fection by the age of 3 years. No cure ex<strong>is</strong>ts<br />

for RSV <strong>in</strong>fections. Prophylactic use of IG products <strong>with</strong> high anti-RSV antibody titres or<br />

monoclonal anti-RSV antibody have proved beneficial when given monthly <strong>in</strong> selected<br />

high-r<strong>is</strong>k <strong>in</strong>fants, 136 but are not d<strong>is</strong>cussed <strong>in</strong> th<strong>is</strong> section on polyvalent IG. Several studies<br />

have also assessed the effectiveness of provid<strong>in</strong>g IG for children admitted to hospital for<br />

severe RSV <strong>in</strong>fection as treatment.<br />

A Cochrane review publ<strong>is</strong>hed <strong>in</strong> 2006 evaluated the treatment of RSV <strong>in</strong>fections <strong>with</strong><br />

several types of IG, <strong>in</strong>clud<strong>in</strong>g polyvalent IG, IG <strong>with</strong> high anti-RSV antibody titres and<br />

human<strong>is</strong>ed monoclonal antibody to RSV. 137 It <strong>in</strong>cluded four publications, and no RCT<br />

demonstrated stat<strong>is</strong>tically significant benefit of IG treatment added to supportive care,<br />

compared <strong>with</strong> supportive care alone. No meta-analys<strong>is</strong> was possible due to the wide<br />

heterogeneity of the outcomes assessed. No RCT publ<strong>is</strong>hed after the review period<br />

were found. <strong>The</strong> <strong>available</strong> evidence thus does not support a role of IG for the treatment<br />

of RSV <strong>in</strong>fection, <strong>with</strong> the doses used <strong>in</strong> the studies.<br />

No significant benefit of IG treatment added to supportive care has been shown<br />

for the treatment of RSV <strong>in</strong>fections, compared <strong>with</strong> supportive care alone.<br />

3.2.2.6 Medical conditions under <strong>in</strong>vestigation<br />

Alzheimer d<strong>is</strong>ease<br />

Alzheimer’s d<strong>is</strong>ease (AD) <strong>is</strong> the most common cause of dementia and accounts for<br />

more than half of the dementia cases. One of the major manifestations of AD <strong>is</strong> the<br />

presence of abundant plaques <strong>in</strong> the bra<strong>in</strong> t<strong>is</strong>sues of the affected <strong>in</strong>dividuals, due to<br />

deposits of an amyloid-beta peptide (AbP). <strong>The</strong> dom<strong>in</strong>ant theory states that<br />

overproduction of AbP, or failure to clear th<strong>is</strong> peptide, leads to the neuronal damage. 138<br />

Prelim<strong>in</strong>ary studies have suggested that IG therapy has several positive effects on<br />

patients <strong>with</strong> AD, by lower<strong>in</strong>g the level of soluble AbP <strong>in</strong> the bra<strong>in</strong>. 139 However, no RCT<br />

was found; IG was only shown to have positive effect on AD patients <strong>in</strong> two small and<br />

non-controlled trials. <strong>The</strong> first trial <strong>in</strong>volved 5 AD patients <strong>with</strong> IG monthly for six<br />

months and showed a drop <strong>in</strong> CSF AbP (by 30%) and an <strong>in</strong>crease <strong>in</strong> plasma AbP (by<br />

23%), together <strong>with</strong> a stabilization <strong>in</strong> cognitive decl<strong>in</strong>e <strong>in</strong> all the patients. 140 Another 18month<br />

study <strong>in</strong> 8 patients <strong>with</strong> mild AD receiv<strong>in</strong>g IG led to transient <strong>in</strong>creases <strong>in</strong> plasma<br />

levels of AbP. 141 <strong>The</strong> CSF AbP levels decreased after six months of IG therapy and, after<br />

three months <strong>with</strong>out IG, <strong>in</strong>creased to their pre-treatment basel<strong>in</strong>e levels. <strong>The</strong>se<br />

f<strong>in</strong>d<strong>in</strong>gs <strong>in</strong>dicate that no def<strong>in</strong>ite statement on the effects of IG <strong>in</strong> AD can be made.<br />

Many other agents for passive immunotherapy are under study, mostly monoclonal<br />

antibodies aga<strong>in</strong>st Ab or <strong>in</strong>vestigative vacc<strong>in</strong>es. A phase III trial of pooled human<br />

Chronic fatigue syndrome<br />

<strong>The</strong> Chronic fatigue syndrome (CFS) <strong>is</strong> a condition character<strong>is</strong>ed by severe, d<strong>is</strong>abl<strong>in</strong>g<br />

fatigue <strong>in</strong> the absence of exertion, and <strong>is</strong> marked by a dramatic decl<strong>in</strong>e <strong>in</strong> activity level.<br />

Currently, the aetiology of CFS rema<strong>in</strong>s unknown.<br />

<strong>The</strong> beneficial effect of IG for CFS patients <strong>is</strong> controversial. Three RCTs obta<strong>in</strong>ed mixed<br />

results: a RCT conducted <strong>in</strong> 1990 found improvements <strong>in</strong> symptom scores and<br />

functional capacity at three months; 143 a second found improvement <strong>in</strong> immune<br />

<strong>in</strong>dicators but not <strong>in</strong> symptom and functional measures, 144 the third trial was more<br />

recent and larger (<strong>in</strong>volv<strong>in</strong>g 99 adult patients). 145 It found no effect of treatment, but<br />

<strong>report</strong>ed adverse reactions <strong>in</strong> 70-80% patients, <strong>with</strong> no relationship to IG treatment. It<br />

concluded that IG cannot be recommended as a therapy for CFS.<br />

<strong>The</strong>re <strong>is</strong> conflict<strong>in</strong>g evidence on the effect of IG <strong>in</strong> CFS, but the larger and more<br />

recent trial showed no effect, <strong>with</strong> a high rate of adverse events.<br />

3.3 CONSUMPTION OF IMMUNOGLOBULINS<br />

3.3.1 Consumption <strong>in</strong> other countries<br />

Few studies <strong>in</strong>vestigat<strong>in</strong>g IG use and its trends are <strong>available</strong>. No study has been found on<br />

IG consumption <strong>in</strong> European countries. However, eight studies <strong>with</strong> quantitative data<br />

on recent IG use per <strong>in</strong>dication were found from Australia, Canada, New Zealand and<br />

the US. 146,147,148,149,150,151,152,153 .<br />

major specialty, <strong>is</strong> shown <strong>in</strong> Table 22, based on the four studies analyz<strong>in</strong>g IG use per<br />

<strong>in</strong>dication. Though variations are observed across studies, the majority of IG was<br />

prescribed by two cl<strong>in</strong>ical specialities: neurology, which consume <strong>in</strong> average one third of<br />

total IG amount; and immuno-haematology, which consume around half of the total<br />

amount. An exception to th<strong>is</strong> pattern was the Massachusset general hospital (US) where<br />

<strong>KCE</strong> Reports 120 Plasma 71<br />

<strong>The</strong> analys<strong>is</strong> of IG d<strong>is</strong>tribution per <strong>in</strong>dication shows that a few d<strong>is</strong>eases treated <strong>with</strong><br />

long term ma<strong>in</strong>tenance IG consume a high proportion of the total IG amount. Among<br />

the neurological <strong>in</strong>dications, chronic <strong>in</strong>flammatory demyel<strong>in</strong>at<strong>in</strong>g polyneuropathy (CIDP)<br />

accounts for the highest consumption per d<strong>is</strong>ease (19% of total use <strong>in</strong> average), and<br />

comb<strong>in</strong>ed <strong>with</strong> multifocal motor neuropathy (MMN) consumed as much as 62% of the<br />

IG amount <strong>in</strong> Massachusset, while it represents 11-20% <strong>in</strong> other studies. Among the<br />

immuno-haematological <strong>in</strong>dications, the ma<strong>in</strong> consumers are primary and secondary<br />

immune deficiencies (PID and SID), represent<strong>in</strong>g together 34% of total use (rang<strong>in</strong>g 18-<br />

47%). Idiopathic thrombocytopenic purpura (ITP) and stem cell transplants (<strong>in</strong>cluded <strong>in</strong><br />

secondary immune deficiencies) represents 13 and 11% of total IG use respectively but<br />

th<strong>is</strong> proportion widely varies across countries, reflect<strong>in</strong>g diverg<strong>in</strong>g views on the IG use<br />

for these <strong>in</strong>dications.<br />

Similar geographical variations were observed across Canadian regions (Tonronto vs.<br />

146, 148, 151<br />

Atlantic regions), as well as across Australian regions.<br />

Some other specialties or <strong>in</strong>dications were responsible for a high IG use, which<br />

contrasted <strong>with</strong> the recommendations <strong>in</strong> use. For <strong>in</strong>stance, the Toronto study showed<br />

an unexpectedly high amount of IG used for <strong>in</strong>fectious d<strong>is</strong>eases (18%) and dermatology<br />

(7%). 148 Unexpected patterns of IG use were also observed <strong>in</strong> specific regions: <strong>in</strong> the<br />

New Zealand study, one region was an extraord<strong>in</strong>arily high user of IG for obstetric<br />

purposes, us<strong>in</strong>g 11-fold more IG per capita <strong>in</strong> th<strong>is</strong> category than the other regions, and<br />

also used large amounts for respiratory and rheumatic d<strong>is</strong>eases. Another region used<br />

more IG for cardiological diagnoses than all other regions comb<strong>in</strong>ed. 149 <strong>The</strong> Toronto<br />

study also noticed that <strong>in</strong>dividual physicians <strong>with</strong> specific cl<strong>in</strong>ical <strong>in</strong>terest were<br />

responsible for large proportions of the total IG prescribed. 148 A high number of<br />

patients received IG as a s<strong>in</strong>gle dose, for other <strong>in</strong>dications that those commonly<br />

accepted; each patient consumed relatively little IG but made up of nearly one-third of<br />

all patients treated. Most of these s<strong>in</strong>gle-use patients probably represents empirical use<br />

of IG <strong>in</strong> which a cl<strong>in</strong>ician attempts to rescue a seriously ill patient for whom there are<br />

few other treatments <strong>available</strong>, or when physicians are confronted <strong>with</strong> an undef<strong>in</strong>ed<br />

medical problem, such as a peripheral neuropathy. Th<strong>is</strong> pattern was also suggested by<br />

the Canadian Atlantic study. 146<br />

<strong>The</strong> d<strong>is</strong>tribution of the total number of patients treated <strong>with</strong> IG per d<strong>is</strong>ease (Table 23)<br />

suggests a similar d<strong>is</strong>tribution. However, the proportion of patients treated for<br />

neurological d<strong>is</strong>orders tends to be lower than the respective proportion of IG use,<br />

especially <strong>in</strong> Massachusset where 39% cases <strong>with</strong> neurological d<strong>is</strong>order consume 71% of<br />

total IG use. Th<strong>is</strong> <strong>is</strong> due to the high amount of IG used for the long term immunomodulatory<br />

treatment of neurological <strong>in</strong>dications such as CIDP and MMN: the dosage<br />

ranges 1-2g/kg body weight (vs. 0.3-0.6g for PID and 0.8-1g for ITP) and these patients<br />

are mostly adults.<br />

<strong>The</strong> average IG amount used to treat a case <strong>with</strong> a def<strong>in</strong>ed d<strong>is</strong>ease <strong>is</strong> presented <strong>in</strong> Table<br />

24. It <strong>in</strong>deed confirms the (non significantly) higher average dose per patient used to<br />

treat the neurological d<strong>is</strong>eases (rang<strong>in</strong>g 173-486g per patient) as compared to immunohaematological<br />

<strong>in</strong>dications (rang<strong>in</strong>g 90-302g per patient). D<strong>is</strong>eases rank<strong>in</strong>g the highest <strong>in</strong><br />

IG use per patient (weighted average) were dermatomyosit<strong>is</strong>, multiple scleros<strong>is</strong>, CIDP,<br />

MMN, stem cell transplant, acute leukaemia and solid organ transplants. Primary and<br />

other secondary immune deficiencies are consum<strong>in</strong>g lower amounts per case (rang<strong>in</strong>g<br />

150-229g per patient), due to the lower dosage per kg used for IG supplementation.

3.3.1.2 Trends over time<br />

An <strong>in</strong>crease <strong>in</strong> overall IG consumption has been described worldwide. For <strong>in</strong>stance,<br />

annual util<strong>is</strong>ation <strong>in</strong> Australia rose by an average of 14.8% from 1994-95 to 2004-05. 16 In<br />

Canada, the IG use has steadily r<strong>is</strong>en s<strong>in</strong>ce 1990, at a mean annual rate of 12.5%. 146<br />

However, only a few studies have analyzed the d<strong>is</strong>tribution of IG use per <strong>in</strong>dication (or<br />

specialty) over time. An unpubl<strong>is</strong>hed US study shows that the weight of each medical<br />

specialty has undergone noticeable changes <strong>with</strong><strong>in</strong> a 5-year period of time (2002-2007,<br />

Table 25). <strong>The</strong> Toronto study <strong>report</strong>ed that dermatological conditions <strong>in</strong>creased from<br />

0% of annual consumption <strong>in</strong> 1995 to 16% by 2000, and th<strong>is</strong> was l<strong>in</strong>ked to the<br />

establ<strong>is</strong>hment of specialized dermatological cl<strong>in</strong>ics. 148<br />

Th<strong>is</strong> suggests that diversification <strong>in</strong> IG use or IG demand, result<strong>in</strong>g from either newly<br />

approved <strong>in</strong>dications or changes <strong>in</strong> prescription practices, may appear <strong>in</strong> any country <strong>in</strong><br />

a relatively short period of time.<br />

3.3.1.3 Unlabelled use of immunoglobul<strong>in</strong><br />

Several studies compared the proportion of IG used or the proportion of patients<br />

treated <strong>with</strong> IG for an unlabelled <strong>in</strong>dication, as def<strong>in</strong>ed <strong>in</strong> each country (Table 26). 146 It <strong>is</strong><br />

noteworthy that these unlabelled <strong>in</strong>dications represented more than half of the total<br />

number of patients receiv<strong>in</strong>g IG (52-64%) <strong>in</strong> all studies. However, most of these IG<br />

adm<strong>in</strong><strong>is</strong>trations were scientifically accepted and often <strong>in</strong>cluded <strong>in</strong> the national<br />

recommendations, <strong>in</strong> accordance <strong>with</strong> the last guidel<strong>in</strong>es. Th<strong>is</strong> concept of labelled and<br />

unlabelled <strong>in</strong>dication for IG <strong>is</strong> thus no longer related to the concept of scientifically<br />

proven benefit. In Canada (Atlantic Prov<strong>in</strong>ces), the <strong>in</strong>troduction of detailed<br />

recommendations did not impact on the proportion of IG adm<strong>in</strong><strong>is</strong>tered for unlabelled<br />

<strong>in</strong>dications, at least <strong>in</strong> the first year. 146<br />

Key po<strong>in</strong>ts<br />

• In other <strong>in</strong>dustrialized countries, around half of the total amount of<br />

immunoglobul<strong>in</strong>s <strong>is</strong> used to treat immuno-haematological d<strong>is</strong>eases, and<br />

around one third <strong>is</strong> used to treat neurological and neuro-muscular d<strong>is</strong>eases.<br />

• Some specialities or <strong>in</strong>dications that are usually not <strong>in</strong>cluded <strong>in</strong><br />

recommendations consume an unexpectedly high amount of IG, <strong>with</strong> large<br />

variations across hospitals and geographical areas. Individual physicians or<br />

cl<strong>in</strong>ics may impact on large proportions of the total IG prescribed<br />

• A few d<strong>is</strong>eases consume a high proportion of the total IG. For <strong>in</strong>stance, four<br />

d<strong>is</strong>eases (chronic <strong>in</strong>flammatory demyel<strong>in</strong>at<strong>in</strong>g polyneuropathy, primary and<br />

secondary immune deficiencies and idiopathic thrombocytopenic purpura)<br />

consumed <strong>in</strong> average two third of the total IG amount. Three of these<br />

d<strong>is</strong>eases require long term treatment <strong>with</strong> IG.<br />

3.3.2 Consumption <strong>in</strong> Belgium<br />

3.3.2.1 Methods<br />

Data on IG use <strong>in</strong> Belgium were collected from two sources:<br />

1. Data on the period January 2004 - June 2007 from the National Institute for<br />

Health and D<strong>is</strong>ability Insurance (INAMI/RIZIV) on the IG amounts<br />

reimbursed, per quarter;<br />

2. Data on the year 2008 on IG used by hospitals (reimbursed or not) and<br />

collected by an ad-hoc survey.<br />

<strong>The</strong> <strong>KCE</strong> carried out a survey <strong>in</strong> March-June 2009 addressed to all pharmac<strong>is</strong>ts<br />

responsible for hospital pharmacies <strong>in</strong> Belgium, <strong>with</strong> the collaboration of the two<br />

regional associations of hospital pharmac<strong>is</strong>ts. We requested data on the amount of each<br />

IG brand product (per label and dosage) used <strong>in</strong> 2008, by medical specialty of the<br />

prescriber, based on the last three numbers of the INAMI/RIZIV codes. All nonrespond<strong>in</strong>g<br />

hospitals that had consumed >1 500 gr or spent >60 000€ for IG <strong>in</strong> 2006<br />

were then contacted personally.<br />

Data were then analyzed by summ<strong>in</strong>g all brand products expressed <strong>in</strong> grams.<br />

D<strong>is</strong>tribution per hospital, medical specialties and type of producer (CAF and non-CAF)<br />

are presented. Though data come from two non-fully comparable sources, we have<br />

compared data over the 2004-2008 period to identify trends.<br />

Information on the <strong>in</strong>dications for which IG has been prescribed <strong>is</strong> not <strong>available</strong>. Th<strong>is</strong><br />

survey does not aim at assess<strong>in</strong>g the relevance of IG prescription <strong>in</strong> hospitals.<br />

3.3.2.2 Overall IG amounts used <strong>in</strong> 2004-2008<br />

INAMI/RIZIV data for the 2004-2006 period have been presented under “Use of plasma<br />

derivatives <strong>in</strong> Belgium” and are compared below to the 2008 data (Figure 7).<br />

<strong>The</strong> <strong>KCE</strong> received data on 2008 IG amounts used from 102 hospitals <strong>report</strong><strong>in</strong>g a total<br />

use of 919.6 kg of IG, all products comb<strong>in</strong>ed. <strong>The</strong>se 102 hospitals represent a response<br />

rate of 82% on the 125 hospitals that <strong>report</strong>ed IG use <strong>in</strong> 2006 and accounted for as<br />

much as 99% of national IG use <strong>in</strong> 2006.

Figure 7 shows the yearly <strong>in</strong>crease of IG consumed over the period 2004-2008 and its<br />

l<strong>in</strong>ear trend. Data on 2007 are only <strong>available</strong> for the first two quarter of 2007. It must<br />

be noted that the two data sources are not fully comparable: 2004-2006 data cover<br />

reimbursed IG data provided by INAMI/RIZIV <strong>in</strong> all Belgian hospitals; 2008 data<br />

collected by the survey cover reimbursed and non-reimbursed IG <strong>report</strong>ed by Belgian<br />

hospitals represent<strong>in</strong>g 99% of IG use <strong>in</strong> 2006. However, we observed that the 2008<br />

estimate fits <strong>with</strong> the l<strong>in</strong>ear trend on the 2004-2006 data.<br />

Figure 8 presents the evolution (per quarter) of <strong>in</strong>travenous IG (IVIG) used, per<br />

producer (CAF-DCF and other producers). <strong>The</strong> systematically lower consumption <strong>in</strong><br />

the third quarter may be expla<strong>in</strong>ed by the d<strong>is</strong>cont<strong>in</strong>uation of IG supplementation <strong>in</strong> mild<br />

immune deficiencies dur<strong>in</strong>g summer (see Patterns of use). <strong>The</strong> proportion of CAF-DCF<br />

IVIG used <strong>in</strong>creased over the period (except <strong>in</strong> 2007) to reach 54.4% of all IVIG <strong>in</strong> the<br />

second quarter of 2008.<br />

In Figure 9, the IG consumption over the years 2004, 2006 and 2008 <strong>is</strong> compared for<br />

the 20 hospitals show<strong>in</strong>g the highest IG consumption. <strong>The</strong> absolute amounts of IG used<br />

are not compared across hospitals by level of activity, by lack of suitable criteria or<br />

<strong>in</strong>dicator. But the compar<strong>is</strong>on of trends across hospitals show divergences <strong>in</strong> IG<br />

consumption trends over th<strong>is</strong> 5 year period: some hospitals have nearly doubled their<br />

IG use (hospitals 10, 12 and 17), others showed a milder <strong>in</strong>crease or a relative<br />

stabilization of IG use, and a m<strong>in</strong>ority of them have decreased IG use from 2004 to<br />

2008.

In Table 30, we observe a severe d<strong>is</strong>crepancy between the prescription of IG by lung<br />

special<strong>is</strong>ts <strong>in</strong> academic and the prescription <strong>in</strong> non-academic hospitals: the Flem<strong>is</strong>h<br />

hospital where lung special<strong>is</strong>ts prescribed the highest IG amount accounted for 21.1 kg<br />

or 4.6 times the amount consumed <strong>in</strong> all university hospitals comb<strong>in</strong>ed. <strong>The</strong> <strong>French</strong>speak<strong>in</strong>g<br />

hospital hav<strong>in</strong>g prescribed most IG <strong>in</strong> pneumology, consumed three times the<br />

amount prescribed <strong>in</strong> all <strong>French</strong>-speak<strong>in</strong>g university hospitals. In both hospitals, IG<br />

prescribed by pneumolog<strong>is</strong>ts represented more than 60% of the IG prescribed for the<br />

whole hospital, while th<strong>is</strong> proportion represents 1.4% and 2.4% <strong>in</strong> academic hospitals.<br />

Th<strong>is</strong> high prescription for lung d<strong>is</strong>ease <strong>is</strong> especially noticeable <strong>in</strong> Flanders: <strong>in</strong> at least 11<br />

non-academic hospitals, over 50% of the total IG <strong>is</strong> prescribed by pneumolog<strong>is</strong>ts. Th<strong>is</strong><br />

prescription pattern and high IG use <strong>in</strong> pneumology cannot be unexpla<strong>in</strong>ed by current<br />

reimbursed <strong>in</strong>dications, as no respiratory pathology <strong>is</strong> <strong>in</strong>cluded <strong>in</strong> the current<br />

<strong>in</strong>dications for IG, except for agammaglobul<strong>in</strong>emia and hypogammaglobul<strong>in</strong>emia <strong>with</strong><br />

repeated bacterial <strong>in</strong>fections that may affect the respiratory tract. Experts <strong>report</strong>ed that<br />

IG <strong>is</strong> frequently prescribed <strong>in</strong> some peripheral hospitals for other immune deficiencies,<br />

such as <strong>is</strong>olated Ig G subclasses deficiencies <strong>with</strong>out recurrent <strong>in</strong>fections and <strong>with</strong>out<br />

abnormal antibody response after pneumococcal vacc<strong>in</strong>ation. However, these patients<br />

are neither an <strong>in</strong>dication for IG nor <strong>is</strong> IG reimbursed for these situations. It should also<br />

be noted that the criteria for IG reimbursement clearly state that “IG are not<br />

reimbursed if the IgG/IgG2/IgG3 deficiency <strong>is</strong> due to a long term treatment <strong>with</strong><br />

steroids, for <strong>in</strong>stance as <strong>in</strong> the chronic obstructive pulmonary d<strong>is</strong>ease”.<br />

In a few other specialties, similar patterns are also observed, to a lower extent: a high<br />

level of heterogeneity <strong>in</strong> prescription <strong>is</strong> seen across hospitals and some hospitals are<br />

prescrib<strong>in</strong>g significant IG amount <strong>in</strong> some specialties for which no <strong>in</strong>dication <strong>is</strong><br />

reimbursed or usually recommended based on evidence; for <strong>in</strong>stance, <strong>in</strong> surgery,<br />

obstetrics, gynaecology and gastro-enterology.

3.3.2.4 D<strong>is</strong>cussion on IG consumption<br />

Data on IG consumption <strong>in</strong> Belgium <strong>in</strong>dicate similar patterns than those found <strong>in</strong> other<br />

countries: IG consumption <strong>is</strong> <strong>in</strong>creas<strong>in</strong>g over time, four ma<strong>in</strong> specialties consume the<br />

majority of IG, the use of IG <strong>is</strong> heterogeneous across hospitals and some hospitals<br />

consume a high IG amount <strong>in</strong> specialties that are not related to the authorized or<br />

reimbursed <strong>in</strong>dications.<br />

Two additional f<strong>in</strong>d<strong>in</strong>gs <strong>in</strong> Belgium have been revealed by the <strong>KCE</strong> survey:<br />

1. A high amount of IG <strong>is</strong> prescribed by lung special<strong>is</strong>ts, though th<strong>is</strong> cannot be<br />

justified by current reimbursed <strong>in</strong>dications or <strong>available</strong> evidence, as no<br />

respiratory pathology <strong>is</strong> <strong>in</strong>cluded <strong>in</strong> the current <strong>in</strong>dications for IG (except for<br />

specific immune deficiencies <strong>with</strong> repeated respiratory tract <strong>in</strong>fections). Th<strong>is</strong><br />

was not observed <strong>in</strong> any of the academic hospitals but was predom<strong>in</strong>ant <strong>in</strong> 11<br />

Flem<strong>is</strong>h and one Walloon hospitals. At <strong>in</strong>ternational level, th<strong>is</strong> was only<br />

<strong>report</strong>ed <strong>in</strong> one region <strong>in</strong> the New Zealand study. As we did not have access<br />

to data on IG consumption per <strong>in</strong>dication, we could not expla<strong>in</strong> th<strong>is</strong><br />

prescription <strong>with</strong> <strong>available</strong> data. Th<strong>is</strong> f<strong>in</strong>d<strong>in</strong>g deserves further <strong>in</strong>vestigation.<br />

2. <strong>The</strong> survey showed wide variations <strong>in</strong> prescription patterns between<br />

academic and non-academic hospitals. A major f<strong>in</strong>d<strong>in</strong>g <strong>is</strong> that a number of<br />

non-academic hospitals prescribe significant IG amounts for four other<br />

specialties (surgery, obstetrics, gynaecology and gastro-enterology) that are<br />

not related to reimbursed <strong>in</strong>dications - or to other <strong>in</strong>dications for which a<br />

benefit of IG has been proven. Th<strong>is</strong> unexpectedly high IG use <strong>is</strong> not observed<br />

<strong>in</strong> academic hospitals. Unexpected patterns of IG use <strong>in</strong> some hospitals or<br />

geographical areas were also observed <strong>in</strong> New Zealand where one region<br />

used 11-fold more IG per capita for obstetric purposes than the other<br />

regions. <strong>The</strong> Toronto study also noticed that <strong>in</strong>dividual physicians <strong>with</strong><br />

specific cl<strong>in</strong>ical <strong>in</strong>terest were responsible for large proportions of the total IG<br />

prescribed.<br />

<strong>The</strong> reasons for the overall <strong>in</strong>crease <strong>in</strong> IG consumption over the recent years could not<br />

be <strong>in</strong>vestigated based on these Belgian data. We had no access to data allow<strong>in</strong>g us to<br />

determ<strong>in</strong>e for which <strong>in</strong>dications IG has been prescribed over time.


82 Plasma <strong>KCE</strong> Reports 120<br />

For <strong>in</strong>stance, a growth <strong>in</strong> IG used <strong>in</strong> neurology was expected <strong>with</strong> the gradual<br />

<strong>in</strong>troduction of CIDP and MMN <strong>in</strong> the l<strong>is</strong>t of reimbursed <strong>in</strong>dications over 2002-2008<br />

(Table 19), but th<strong>is</strong> could not be verified. It <strong>is</strong> remarkable to observe that a few<br />

hospitals have decreased their IG consumption while others have doubled it over a 5<br />

year period.<br />

3.3.2.5 Patterns of use<br />

In order to understand IG use <strong>in</strong> Belgium and help determ<strong>in</strong>e the IG amount that would<br />

be required to treat the most IG consum<strong>in</strong>g <strong>in</strong>dications, two expert meet<strong>in</strong>gs and a<br />

survey were organized. <strong>The</strong> aim was to assess current practices <strong>in</strong> Belgium regard<strong>in</strong>g<br />

the character<strong>is</strong>tics of patients treated, the dosage used, the frequency of IG treatment<br />

<strong>in</strong> ma<strong>in</strong>tenance therapy and the expected trends <strong>in</strong> IG use.<br />

In immuno-haematological d<strong>is</strong>eases<br />

A survey was undertaken among 10 ma<strong>in</strong> centres adm<strong>in</strong><strong>is</strong>ter<strong>in</strong>g IG for immunodeficiencies.<br />

Questionnaires were addressed to paediatricians and haematolog<strong>is</strong>ts to<br />

obta<strong>in</strong> <strong>in</strong>formation on how IG are used <strong>in</strong> Belgium. We requested 2008 data on the<br />

number of patients treated per reimbursed <strong>in</strong>dication, number of IG adm<strong>in</strong><strong>is</strong>trations and<br />

usual dosage for the reimbursed <strong>in</strong>dications. Responses were received from 7 hospitals,<br />

and 6 hospitals provided the data requested. Survey results were presented to an<br />

expert committee and d<strong>is</strong>cussed. <strong>The</strong> questionnaires are provided <strong>in</strong> appendix.<br />

Collected questionnaires covered 846 cases, <strong>in</strong>clud<strong>in</strong>g 562 cases <strong>with</strong> an immunological<br />

or haematological d<strong>is</strong>ease or a Kawasaki d<strong>is</strong>ease: 186 cases <strong>with</strong> primary immune<br />

deficiency (PID) under ma<strong>in</strong>tenance treatment, 148 transplant cases, 75 ITP cases, 58<br />

cases <strong>with</strong> MM or CLL, 31 Kawasaki d<strong>is</strong>ease cases, 37 neonates treated <strong>with</strong> IG for<br />

<strong>in</strong>fection or severe ABO <strong>in</strong>compatibility and 27 cases <strong>with</strong> other immune deficiencies.<br />

Among these cases, 338 were children (154 PID, 36 transplants, 53 ITP, 31 Kawasaki<br />

d<strong>is</strong>ease, 37 neonates and 27 other immune deficiencies).<br />

No cases treated <strong>with</strong> IG for septic shock syndrome were <strong>report</strong>ed, though th<strong>is</strong> <strong>is</strong> a<br />

reimbursed <strong>in</strong>dication for IG. Based on several assumptions, we estimated that all these<br />

cases - <strong>with</strong> the exclusion of neurological <strong>in</strong>dications - accounted for a total IG use of<br />

108 kg <strong>in</strong> 2008, represent<strong>in</strong>g around 12% of total national use <strong>in</strong> 2008.<br />

DOSAGE PER INDICATION<br />

Results showed that similar dosage of IG supplementation per kg body weight are<br />

adm<strong>in</strong><strong>is</strong>tered <strong>in</strong> all centres to PID cases (around 0.4g), <strong>in</strong> accordance <strong>with</strong> guidel<strong>in</strong>es<br />

publ<strong>is</strong>hed by the Primary Immune deficiency Belgian group, 34 and for transplant cases.<br />

But dosage for other <strong>in</strong>dications showed wide variations. In ITP, doses ranged 0.8-2g/kg;<br />

two hospitals use a dose of 0.8g/kg <strong>in</strong> children as it has shown similar efficacy than<br />

higher doses <strong>in</strong> a recent study. In Kawasaki d<strong>is</strong>ease, dose ranged 1 to 2g/kg but 2g was<br />

the most frequent. For the other <strong>in</strong>dications, only one or two centres <strong>report</strong>ed cases<br />

and no conclusion can be drawn.<br />

FREQUENCY OF TREATMENT<br />

<strong>The</strong> annual frequency and duration of <strong>in</strong>travenous IG (IVIG) adm<strong>in</strong><strong>is</strong>trations per patient<br />

requir<strong>in</strong>g long term treatment also showed differences across centres:<br />

• For PID, the frequency of IVIG adm<strong>in</strong><strong>is</strong>tration varied from an average of<br />

6.4 to 14.3 per year <strong>in</strong> 2008. However, centres <strong>report</strong><strong>in</strong>g a lower<br />

frequency had many patients switch<strong>in</strong>g from IV to SC adm<strong>in</strong><strong>is</strong>tration <strong>in</strong><br />

2008 and a more documented monitor<strong>in</strong>g. In addition, the frequency <strong>in</strong> IG<br />

adm<strong>in</strong><strong>is</strong>tration depends on the type of immune deficiency: patient <strong>with</strong><br />

severe antibody deficiencies must receive treatment all year long, mostly<br />

every 3-4 weeks, requir<strong>in</strong>g 12-14 adm<strong>in</strong><strong>is</strong>trations per year; while <strong>in</strong><br />

transient or mild hypogammaglobul<strong>in</strong>emia <strong>with</strong> recurrent severe<br />

<strong>in</strong>fections, IG treatment can be stopped dur<strong>in</strong>g summer.


<strong>KCE</strong> Reports 120 Plasma 83<br />

• For bone marrow or stem cell transplant, the frequency of adm<strong>in</strong><strong>is</strong>tration<br />

averaged 10.8 per year, rang<strong>in</strong>g 2.6-12.9. In general <strong>in</strong> children, treatment<br />

<strong>is</strong> adm<strong>in</strong><strong>is</strong>tered before transplant and dur<strong>in</strong>g at least 3 months, mostly 6<br />

months and up to 1-2 years <strong>in</strong> cases of pers<strong>is</strong>tent B-cell abnormalities.<br />

However, the recent decrease <strong>in</strong> myeloablative transplants, due to an<br />

<strong>in</strong>crease <strong>in</strong> non-myeloablative techniques, has decreased the level and<br />

duration of secondary immune deficiency - and the consequent IG needs.<br />

Th<strong>is</strong> <strong>is</strong> mostly described <strong>in</strong> adult patients.<br />

• For ITP, the frequency of adm<strong>in</strong><strong>is</strong>tration was not <strong>available</strong> <strong>in</strong> most<br />

hospitals but was 1.4 per case <strong>in</strong> average <strong>in</strong> 3 hospitals.<br />

• In Kawasaki d<strong>is</strong>ease, the frequency of adm<strong>in</strong><strong>is</strong>tration could not be<br />

establ<strong>is</strong>hed based on <strong>available</strong> data, but experts adv<strong>is</strong>ed the adm<strong>in</strong><strong>is</strong>tration<br />

of a s<strong>in</strong>gle dose, followed by a 2nd dose <strong>in</strong> a few patients <strong>in</strong> which<br />

<strong>in</strong>flammatory signs and symptoms are still present.<br />

WHICH CASES SHOULD BE TREATED WITH IG<br />

<strong>The</strong> proportion of patients receiv<strong>in</strong>g IG for each of these <strong>in</strong>dications <strong>in</strong> Belgium was<br />

difficult to assess <strong>in</strong> th<strong>is</strong> survey, as cl<strong>in</strong>icians could not always collect data on the total<br />

number of cases that v<strong>is</strong>ited their centre.<br />

For bone marrow or stem cell transplant, paediatricians considered that nearly all<br />

paediatric cases require IG supplementation; <strong>in</strong> adults, only a selected subgroup of<br />

patients hav<strong>in</strong>g a symptomatic secondary immunodeficiency follow<strong>in</strong>g the transplant can<br />

benefit from IG treatment, and th<strong>is</strong> should be decided on an <strong>in</strong>dividual bas<strong>is</strong>.<br />

Secondary immune deficiencies due to the use of therapies deplet<strong>in</strong>g B-cells or impair<strong>in</strong>g<br />

B-cell response (eg. some anticancer drugs) and <strong>in</strong>duc<strong>in</strong>g symptomatic<br />

hypogammaglobul<strong>in</strong>emia are also medical conditions for which IG may be necessary.<br />

Experts proposed that cases <strong>with</strong> secondary hypogammaglobul<strong>in</strong>emia be treated <strong>with</strong> IG<br />

dur<strong>in</strong>g for the period of the hypogammaglobul<strong>in</strong>emia, irrespective of its cause. Th<strong>is</strong> <strong>is</strong><br />

l<strong>in</strong>e <strong>with</strong> the approach of PID cases, though the treatment would be mostly limited to a<br />

period of 6-12 months.<br />

ESTIMATION OF AMOUNTS<br />

<strong>The</strong> amount of IG used for each immuno-haematological <strong>in</strong>dication <strong>in</strong> these centres has<br />

been estimated, based on the assumption of an average 75kg body weight per adult, 25<br />

kg per child and 4 kg per neonate. Under these assumptions, treatment of PID patients<br />

would represent 61% of the total IG use for immuno-haematological <strong>in</strong>dications, CLL<br />

and MM 14% and transplants 10%. However, these estimates are biased by a better<br />

response rate among paediatricians as compared to haematolog<strong>is</strong>ts treat<strong>in</strong>g adult cases.<br />

USE OF SUB-CUTANEOUS IG<br />

Subcutaneous adm<strong>in</strong><strong>is</strong>tration of IG was used for PID <strong>in</strong> 5 out of the 6 hospitals and used<br />

to treat 44% of the PID paediatric cases <strong>in</strong> average. Th<strong>is</strong> practice was predom<strong>in</strong>ant <strong>in</strong><br />

two hospitals where 48-71% of PID children received SC adm<strong>in</strong><strong>is</strong>tration, and <strong>is</strong> a<br />

grow<strong>in</strong>g practice <strong>in</strong> the other paediatric wards of these centres. Expert paediatricians<br />

consider that SC adm<strong>in</strong><strong>is</strong>tration <strong>is</strong> a first choice for long-term treatment as it improves<br />

quality of life of the patient and <strong>is</strong> more effective to control immunodeficiencies, as IG<br />

levels are better ma<strong>in</strong>ta<strong>in</strong>ed <strong>with</strong> weekly <strong>in</strong>fusions. In adult cases however, only two out<br />

In neurological d<strong>is</strong>eases<br />

In order to know the current use of IG <strong>in</strong> Belgium for the neurological and neuromuscular<br />

<strong>in</strong>dications consum<strong>in</strong>g large amounts of IG, an expert meet<strong>in</strong>g was organized.<br />

<strong>The</strong> criteria for IG treatment, proportion of cases treated, dosage and frequency of IG<br />

treatment were d<strong>is</strong>cussed, based on <strong>in</strong>formation found <strong>in</strong> the scientific literature and<br />

the Belgian situation. <strong>The</strong> survey also collected data on 284 IG adm<strong>in</strong><strong>is</strong>trations for<br />

neurological cases (Guilla<strong>in</strong> Barré d<strong>is</strong>ease, CIDP and MMN).


84 Plasma <strong>KCE</strong> Reports 120<br />

However, results should be taken <strong>with</strong> caution as data were only provided by 3<br />

hospitals and were not exhaustive for each hospital (focus on paediatrics). <strong>The</strong> ma<strong>in</strong><br />

f<strong>in</strong>d<strong>in</strong>gs are summarized below:<br />

• For Guilla<strong>in</strong> Barré syndrome, dosage and frequency described <strong>in</strong> the<br />

literature <strong>is</strong> also applied <strong>in</strong> Belgium. In the above mentioned survey, only<br />

34 cases were <strong>report</strong>ed by 3 hospitals, and data on adult cases were only<br />

<strong>report</strong>ed by one hospital. IG dosage ranged 1 to 2g/kg <strong>in</strong> the 3 hospitals.<br />

• For CIDP, the Moniteur Belge / Belg<strong>is</strong>ch Staatblad (MB/BS) stipulates that<br />

the first l<strong>in</strong>e treatment <strong>is</strong> steroids, and only patients <strong>with</strong> contra<strong>in</strong>dications<br />

or treatment failure to steroids should receive IG. Experts<br />

estimate that about two-third of CIDP patients receive IG treatment. Th<strong>is</strong><br />

proportion also depends on the cl<strong>in</strong>ician expert<strong>is</strong>e; unnecessary IG<br />

treatment has been observed <strong>in</strong> patients referred by peripheral centres to<br />

the university centres. Dosage also ranges 1 to 2g/kg. <strong>The</strong> current<br />

practice <strong>is</strong> to rapidly decrease the <strong>in</strong>itial dose accord<strong>in</strong>g to the cl<strong>in</strong>ical<br />

response, then to reach a m<strong>in</strong>imal ma<strong>in</strong>tenance dose. Th<strong>is</strong> dose be<strong>in</strong>g<br />

patient-dependant, no strict guidel<strong>in</strong>e can be establ<strong>is</strong>hed. <strong>The</strong> upper limit<br />

<strong>in</strong> IG quantities accepted for reimbursement <strong>in</strong> the MB/BS (9g/kg per<br />

semester) <strong>is</strong> considered by experts as too low to treat some specific<br />

cases. Treatment requires good knowledge of the d<strong>is</strong>ease and its cl<strong>in</strong>ical<br />

manifestations.<br />

• For MMN, a higher proportion of cases are treated because mild d<strong>is</strong>ease<br />

<strong>is</strong> less frequent and there <strong>is</strong> no alternative treatment. <strong>The</strong> dose also needs<br />

to be adapted to the cl<strong>in</strong>ical response, and the treatment <strong>is</strong> more difficult<br />

to adjust than for CIDP. It may require <strong>in</strong>creas<strong>in</strong>g doses and decreas<strong>in</strong>g<br />

treatment <strong>in</strong>tervals, especially <strong>in</strong> the long term, due to a known decl<strong>in</strong>e of<br />

treatment effectiveness after prolonged treatment. However a few<br />

patients may have susta<strong>in</strong>ed rem<strong>is</strong>sion and even stop treatment. <strong>The</strong><br />

average dose usually varies from 0.4 to 1g/kg.<br />

• IgM paraprote<strong>in</strong> demyel<strong>in</strong>at<strong>in</strong>g neuropathies are treated <strong>with</strong> IG if they fit<br />

<strong>with</strong> the criteria establ<strong>is</strong>hed for CIDP. <strong>The</strong>se cases represent 5-10% of<br />

CIDP cases.<br />

• In multiple scleros<strong>is</strong> (MS), IG <strong>is</strong> ma<strong>in</strong>ly used <strong>in</strong> the pre and post-partum<br />

period to reduce relapses. IG may also be used <strong>in</strong> the few MS cases <strong>with</strong><br />

relaps<strong>in</strong>g-remitt<strong>in</strong>g cases that do not respond to steroids; one s<strong>in</strong>gle<br />

treatment <strong>is</strong> given <strong>in</strong> case of relapse. Some private <strong>in</strong>surance companies<br />

are cover<strong>in</strong>g the costs. Th<strong>is</strong> concerns a very small number of cases. All<br />

together, the proportion of all MS cases that are treated <strong>with</strong> IG <strong>is</strong><br />

estimated to range 0-3%, as observed <strong>in</strong> other countries.<br />

• In myasthenia grav<strong>is</strong> (MG), IG <strong>is</strong> only used <strong>in</strong> cases that do not respond to<br />

other treatments (plasma exchange and immunosuppressive therapy).<br />

Though IG has replaced plasma exchange as a first l<strong>in</strong>e treatment <strong>in</strong> many<br />

countries, IG <strong>is</strong> not reimbursed for th<strong>is</strong> d<strong>is</strong>ease <strong>in</strong> Belgium - or only by the<br />

solidarity fund when criteria are met. However, due to a lack of expert<strong>is</strong>e<br />

<strong>in</strong> th<strong>is</strong> rare d<strong>is</strong>ease, experts fear that IG would be overused if<br />

reimbursement for MG would be <strong>in</strong>troduced.<br />

• In dermatomyosit<strong>is</strong> and <strong>in</strong>clusion body myosit<strong>is</strong>, IG use for th<strong>is</strong> d<strong>is</strong>ease <strong>is</strong><br />

limited and relatively similar to myasthenia grav<strong>is</strong>.<br />

• Stiff person syndrome <strong>is</strong> a rare d<strong>is</strong>ease, but experts estimated that there<br />

may be around 20 patients <strong>in</strong> Belgium. Plasma exchange <strong>is</strong> the first<br />

treatment option.

3.3.2.6 Limitations<br />

A major limitation of th<strong>is</strong> analys<strong>is</strong> of IG prescription <strong>is</strong> that we have no data <strong>in</strong> 2004-<br />

2006 on non reimbursed IG. Likew<strong>is</strong>e, it <strong>is</strong> unclear whether the IG quantities <strong>report</strong>ed<br />

by hospitals <strong>in</strong>clude IG prescribed for compassionate use. Accord<strong>in</strong>g to some experts,<br />

compassionate use may represent a significant proportion of IG consumption. Th<strong>is</strong> <strong>is</strong><br />

likely result<strong>in</strong>g <strong>in</strong> an underestimation of overall IG consumption.<br />

Another limitation of th<strong>is</strong> survey and expert meet<strong>in</strong>g <strong>is</strong> the lack of representativeness of<br />

the Belgium situation: it only <strong>in</strong>volved cl<strong>in</strong>icians work<strong>in</strong>g <strong>in</strong> large university centres and a<br />

small numbers of experts (only paediatricians for the immuno-haematological<br />

<strong>in</strong>dications) could attend. Problems of higher dose, higher frequency and non-<strong>in</strong>dicated<br />

IG therapy have been <strong>report</strong>ed <strong>in</strong> peripheral hospitals or practices, but <strong>available</strong> data did<br />

not allow <strong>in</strong>vestigat<strong>in</strong>g th<strong>is</strong> hypothes<strong>is</strong>.<br />

However, prescription patterns per specialty tend to confirm th<strong>is</strong> hypothes<strong>is</strong>. Experts<br />

<strong>report</strong>ed that th<strong>is</strong> may be due to the lack of experience among peripheral cl<strong>in</strong>icians, as<br />

the low frequency of these d<strong>is</strong>eases result that non-specialized cl<strong>in</strong>icians rarely<br />

encounter these d<strong>is</strong>eases, added to the fact that strict diagnos<strong>is</strong> criteria are mostly not<br />

required for the reimbursement of IG. Experts also <strong>report</strong>ed a strong lobby from the<br />

plasma <strong>in</strong>dustry to use IG for most hypogammaglobul<strong>in</strong>emia. Th<strong>is</strong> implies that the<br />

estimation of IG quantities based on th<strong>is</strong> survey <strong>is</strong> likely to underestimate the real IG<br />

use.<br />

Key po<strong>in</strong>ts<br />

• IG consumption <strong>is</strong> <strong>in</strong>creas<strong>in</strong>g over time <strong>in</strong> Belgium as <strong>in</strong> other countries.<br />

However, <strong>in</strong>dividual hospitals show diverg<strong>in</strong>g trends: a few hospitals have<br />

decrease their IG consumption while other have doubled it over a 5 year<br />

period.<br />

• Four ma<strong>in</strong> specialties prescribe 92% of the total IG amount prescribed <strong>in</strong><br />

Belgium: <strong>in</strong>ternal medic<strong>in</strong>e (46%), neurology and related d<strong>is</strong>eases (23%), lung<br />

d<strong>is</strong>ease (16%) and paediatrics (6%). <strong>The</strong> high prescription of IG by lung<br />

special<strong>is</strong>ts was neither expected nor <strong>report</strong>ed by studies <strong>in</strong> other countries;<br />

th<strong>is</strong> was only found <strong>in</strong> non-academic hospitals but accounted for a significant<br />

amount of IG use.<br />

• We observed huge variations <strong>in</strong> IG prescriptions across Belgian hospitals, as<br />

also <strong>report</strong>ed <strong>in</strong> other countries. Some non-academic hospitals consume a<br />

high IG amount <strong>in</strong> specialties that are not related to the <strong>in</strong>dications<br />

reimbursed. Experts also <strong>report</strong>ed an over-use of IG for specific immune<br />

deficiencies and peripheral neuropathies <strong>in</strong> peripheral hospitals, where<br />

cl<strong>in</strong>icians may be less familiar to these d<strong>is</strong>eases due to their low prevalence.<br />

• For most immune deficiencies and neurological d<strong>is</strong>orders, academic centres<br />

<strong>report</strong>ed similar practices regard<strong>in</strong>g who should be treated and the dosage.<br />

For two <strong>in</strong>dications, stem cell transplants and idiopathic thrombocytopenic<br />

purpura, practices differed regard<strong>in</strong>g which patients are treated, length of<br />

treatment and dosage.<br />

• <strong>The</strong> long term treatment of these rare immune deficiencies and peripheral<br />

neuropathies requires a good knowledge of the d<strong>is</strong>ease to adapt IG dosage<br />

and frequency of treatment to the cl<strong>in</strong>ical response.<br />

• <strong>The</strong> use of sub-cutaneous IG <strong>is</strong> emerg<strong>in</strong>g for PID cases and was used for 44%<br />

of PID patients <strong>in</strong> academic centres <strong>in</strong> 2008, ma<strong>in</strong>ly for paediatric cases.

3.3.3 Estimation of IG quantities to treat the ma<strong>in</strong> <strong>in</strong>dications<br />

<strong>The</strong> objective of th<strong>is</strong> exerc<strong>is</strong>e was to estimate the needs <strong>in</strong> plasma derivatives that<br />

would be required <strong>in</strong> Belgium to treat the ma<strong>in</strong> <strong>in</strong>dications.<br />

3.3.3.1 Methodology<br />

Th<strong>is</strong> estimation represents the theoretical quantities that are required yearly, based on<br />

two assumptions: <strong>in</strong>dications are clearly def<strong>in</strong>ed, all cases are correctly diagnosed, and<br />

patients under long term IG treatment are receiv<strong>in</strong>g IG all year long, <strong>with</strong>out<br />

<strong>in</strong>terruption.<br />

Selection of d<strong>is</strong>eases<br />

Based on the literature review and the recommendations for IG use <strong>in</strong> Belgium and<br />

other countries, we have selected a first l<strong>is</strong>t of 22 d<strong>is</strong>eases <strong>in</strong> which evidence shows a<br />

benefit of IG, or <strong>in</strong> which sufficient evidence on IG benefit <strong>is</strong> not <strong>available</strong> but for which<br />

IG therapy <strong>is</strong> recommended <strong>in</strong> most <strong>in</strong>dustrialized countries (Table 37).<br />

Based on the analys<strong>is</strong> of the IG amounts used to treat these d<strong>is</strong>eases <strong>in</strong> other countries<br />

(see above), we have selected the 12 d<strong>is</strong>eases that are consum<strong>in</strong>g the highest amount of<br />

IG and accounted for respectively 88%, 80% and 68% of total IG use <strong>in</strong> the US<br />

(Massachusset), New Zealand and Canada (Toronto). Further estimations of IG<br />

quantities have been limited to these 12 d<strong>is</strong>eases.<br />

Data on d<strong>is</strong>ease frequency and IG use per d<strong>is</strong>ease<br />

As data on the number of cases treated for each of these d<strong>is</strong>eases were mostly not<br />

<strong>available</strong> <strong>in</strong> Belgian databases, we have extracted the follow<strong>in</strong>g <strong>in</strong>dicators from studies<br />

conducted <strong>in</strong> other countries:<br />

• <strong>The</strong> yearly <strong>in</strong>cidence and/or prevalence rate, depend<strong>in</strong>g whether the<br />

treatment <strong>is</strong> applied once or as long term ma<strong>in</strong>tenance therapy: <strong>in</strong>cidence<br />

rate was searched when treatment <strong>is</strong> adm<strong>in</strong><strong>is</strong>tered once or twice per<br />

patient; prevalence rate was used for ma<strong>in</strong>tenance treatment. For d<strong>is</strong>ease<br />

present<strong>in</strong>g an acute and a chronic form, both <strong>in</strong>cidence and prevalence<br />

were used.

• <strong>The</strong> proportion of patients treated <strong>with</strong> IG, per d<strong>is</strong>ease.<br />

• <strong>The</strong> dosage used per treatment (g/kg) and the frequency of treatment<br />

(per patient or per year for ma<strong>in</strong>tenance treatment).<br />

<strong>The</strong> source studies were selected accord<strong>in</strong>g to the follow<strong>in</strong>g criteria: studies <strong>in</strong>clud<strong>in</strong>g<br />

data from 1995 onwards, hav<strong>in</strong>g a large study population size (>1 million <strong>in</strong>habitants<br />

mostly), and carried out <strong>in</strong> Western EU countries - or <strong>in</strong> other <strong>in</strong>dustrialized countries<br />

when other EU studies were not <strong>available</strong>. When d<strong>is</strong>ease rates vary significantly per<br />

geographical area (e.g. prevalence of multiple scleros<strong>is</strong> vary<strong>in</strong>g <strong>with</strong> latitude), we have<br />

only consider studies conducted <strong>in</strong> similar geographical areas.<br />

<strong>The</strong> values found for the proportion of patient treated <strong>with</strong> IG, the dosage used per<br />

treatment and the frequency of treatment were d<strong>is</strong>cussed and validated <strong>in</strong> two expert<br />

meet<strong>in</strong>gs. For a few <strong>in</strong>dications, the annual numbers of cases were found <strong>in</strong> Belgian<br />

databases (e.g. transplants). Similarly, the dosage and frequency of adm<strong>in</strong><strong>is</strong>tration<br />

obta<strong>in</strong>ed through the survey <strong>in</strong> Belgian hospitals were used when considered as<br />

methodologically reliable and representative, based on expert op<strong>in</strong>ion and <strong>in</strong>formation<br />

on current practice.<br />

Estimation of the annual IG amounts per d<strong>is</strong>ease<br />

<strong>The</strong> annual IG quantities estimated to treat these 12 d<strong>is</strong>eases <strong>in</strong> Belgium were calculated<br />

based on the follow<strong>in</strong>g:<br />

• Data from other countries were aggregated to produce averages for<br />

<strong>in</strong>cidence or prevalence rate, proportion of patients treated and<br />

frequency of treatment, after be<strong>in</strong>g weighted by survey size (“weighted<br />

average”).<br />

• <strong>The</strong> expected annual number of cases under treatment <strong>in</strong> Belgium was<br />

calculated by multiply<strong>in</strong>g the weighted average of the <strong>in</strong>cidence or<br />

prevalence rate by the Belgian population size (per age group when<br />

relevant) and by the proportion of patients treated <strong>with</strong> IG.<br />

• <strong>The</strong> IG amount used per patient and per year was obta<strong>in</strong>ed by multiply<strong>in</strong>g<br />

the average dosage per treatment (<strong>in</strong> g/kg) by the average body weight<br />

(per age group when relevant) and the frequency of treatment (when<br />

multiple doses are given), named as “method A”. An alternative<br />

estimation (method B) was based on the average IG amounts per case and<br />

per year found <strong>in</strong> studies from other countries (weighted average), see<br />

Table 24.<br />

• <strong>The</strong> annual quantities needed to treat each d<strong>is</strong>ease were obta<strong>in</strong>ed by<br />

multiply<strong>in</strong>g the annual number of patients under treatment by the IG<br />

amount used per patient (by method A and B).<br />

Estimates found for the above <strong>in</strong>dicators are described below. <strong>The</strong> annual IG quantities<br />

estimated to treat these 12 d<strong>is</strong>eases <strong>in</strong> Belgium are described <strong>in</strong> Table 40 and below.<br />

3.3.3.2 Estimates per d<strong>is</strong>ease<br />

Idiopathic Thrombocytopenic Purpura<br />

Idiopathic thrombocytopenic purpura (ITP) can present as acute or chronic d<strong>is</strong>ease;<br />

chronic d<strong>is</strong>ease <strong>is</strong> def<strong>in</strong>ed by a duration of ITP for more than 6 months. Studies on the<br />

<strong>in</strong>cidence of acute and chronic ITP show variations <strong>in</strong> case def<strong>in</strong>ition (especially <strong>in</strong> terms<br />

of threshold for platelet count) and age studied. <strong>The</strong>se directly <strong>in</strong>fluences <strong>in</strong>cidence<br />

estimates as a very sensitive threshold for platelet counts overestimates the frequency<br />

of cl<strong>in</strong>ical ITP, and the frequency of chronic ITP <strong>in</strong>creases <strong>with</strong> age.<br />

IN CHILDREN<br />

Three studies <strong>in</strong> Norway, Germany and Nordic countries, estimated the <strong>in</strong>cidence rate<br />

of acute ITP <strong>in</strong> children us<strong>in</strong>g similar criteria (bleed<strong>in</strong>g +/- platelet count


88 Plasma <strong>KCE</strong> Reports 120<br />

<strong>The</strong> proportion of acute ITP that had evolved <strong>in</strong>to chronic ITP was estimated <strong>in</strong> four<br />

studies <strong>in</strong> Norway, France, Denmark and Nordic countries <strong>in</strong> 1996-99 and ranged 18-<br />

33% (average 26%). 155, 156,157,158 We then extrapolated the <strong>in</strong>cidence rate of chronic ITP<br />

at 0.8 per 100,000 <strong>in</strong> children


<strong>KCE</strong> Reports 120 Plasma 89<br />

In Belgium, a survey cover<strong>in</strong>g 6 centres for paediatric PID and 3 centres for adult PID<br />

<strong>report</strong>ed a total of 437 PID cases under follow up, but th<strong>is</strong> figure <strong>is</strong> also <strong>in</strong>complete.<br />

Among these, 263 have received IG treatment <strong>in</strong> 2008. In order to estimate the total<br />

number of PID cases treated <strong>in</strong> Belgium, we have used as proxy the proportion of all<br />

Belgian bone marrow transplants that were conducted <strong>in</strong> these centres, as <strong>report</strong>ed to<br />

the INAMI/RIZIV. Though the proportion of transplants <strong>is</strong> not directly l<strong>in</strong>ked to the<br />

proportion of PID treated, th<strong>is</strong> was considered as a proxy of specialized immunological<br />

activity of these centres. <strong>The</strong> 6 centres provid<strong>in</strong>g data on paediatric cases and the 3<br />

centres provid<strong>in</strong>g data on adult cases represent respectively 34% and 29% of all marrow<br />

transplants <strong>in</strong> 2007. <strong>The</strong> number of PID cases under treatment <strong>is</strong> thus estimated at 806<br />

cases. In Belgian centres surveyed, the dosage ranged 0.3-0.5g/kg and most centres used<br />

0.4g/kg. <strong>The</strong> annual number of IVIG treatment per year ranged 6.4-14.4 per year for<br />

children (average 11.3) and 12.0-13.3 per year for adults (average 11.8). <strong>The</strong> amount of<br />

IG required for SC adm<strong>in</strong><strong>is</strong>tration has been estimated as equivalent to those required<br />

for IV adm<strong>in</strong><strong>is</strong>tration.<br />

Multiple myeloma (MM)<br />

In Belgium, a range of 617-690 new cases of MM were <strong>report</strong>ed per year to the cancer<br />

reg<strong>is</strong>try <strong>in</strong> 2004-2008 and the <strong>in</strong>cidence <strong>is</strong> <strong>in</strong>creas<strong>in</strong>g <strong>with</strong> age. Prevalence data are not<br />

<strong>available</strong> from Belgium or other EU countries. We used the 2006 age-specific<br />

prevalence rates <strong>report</strong>ed among the white population <strong>in</strong> the US and extrapolated to<br />

the Belgian population by age-group. 8 A number of 2390 prevalent cases of MM are<br />

estimated. Th<strong>is</strong> figure may be an underestimation of the Belgian situation because the<br />

MM <strong>in</strong>cidence rates <strong>in</strong> the US are slightly lower than the Belgian <strong>in</strong>cidence rates.<br />

<strong>The</strong> proportion of MM patients treated was not documented <strong>in</strong> the literature, but<br />

expert advice provided a range of 10-15%, based on experience.<br />

<strong>The</strong> survey among immuno-haematolog<strong>is</strong>ts collected data on MM from one Belgian<br />

university hospital only. <strong>The</strong> dosage of 0.4g/kg was similar to the recommendations of<br />

other countries and <strong>in</strong> average 10 treatments were provided per case and year.<br />

Chronic lymphocytic leukaemia (CLL)<br />

National data are not <strong>available</strong> on the <strong>in</strong>cidence or prevalence of CLL but 636 new<br />

cases of lymphoid leukaemia (acute and chronic) were <strong>report</strong>ed <strong>in</strong> 2008. No prevalence<br />

data were found from other countries. <strong>The</strong> proportion of patients treated was also not<br />

<strong>available</strong>.<br />

As for MM, the survey among immuno-haematolog<strong>is</strong>ts collected data on MM from one<br />

Belgian university hospital only. <strong>The</strong> dosage was 0.4g/kg and an average of 10 treatments<br />

was provided per case and year.<br />

Due to the lack of data, IG amounts required to treat CLL cases could not be<br />

calculated.<br />

Allogenous bone marrow or stem cell transplant (SCT)<br />

<strong>The</strong> number of bone marrow transplants <strong>is</strong> collected by the INAMI/RIZIV <strong>in</strong> the<br />

framework of the convention <strong>with</strong> transplant centres. In 2007, 284 allogenous<br />

transplants were recorded, and the 2005-07 data show a gradual <strong>in</strong>crease <strong>in</strong> the number<br />

of allogenous SCT (+31% <strong>in</strong> 2 years). <strong>The</strong> number of transplant was then estimated at<br />

320 for 2008, assum<strong>in</strong>g a l<strong>in</strong>ear trend from 2005 to 2007. However, th<strong>is</strong> number may be<br />

underestimated as hospitals that are not <strong>in</strong>cluded <strong>in</strong> the Convention may also perform<br />

allogenous SCT (INAMI, personal communication).<br />

<strong>The</strong> proportion of SCT cases receiv<strong>in</strong>g IG supplementation has not been found <strong>in</strong> the<br />

scientific publications. In Belgium, it varies across centres, type of transplant and age<br />

group. <strong>The</strong> <strong>in</strong>crease <strong>in</strong> non-myeloablative SCT, ma<strong>in</strong>ly <strong>in</strong> adults, has likely decrease the<br />

IG needs <strong>in</strong> th<strong>is</strong> group. <strong>The</strong> pr<strong>in</strong>ciple <strong>is</strong> that IG treatment should be adm<strong>in</strong><strong>is</strong>tered <strong>in</strong><br />

cases of severe antibody deficiency and thus tailored to the patient. Among children, the<br />

consensus among paediatricians dur<strong>in</strong>g the expert consultation was that most paediatric<br />

cases require IG supplementation, as post-SCT humoral immunodeficiency <strong>is</strong> common.<br />

Among adults, experts consider that the prophylactic and pre-emptive use of antibiotics,<br />

antifungal and antiviral drugs has replaced the rout<strong>in</strong>e use of IVIG, and that only patients<br />

hav<strong>in</strong>g a (transient) symptomatic secondary immunodeficiency should receive IVIG, on<br />

an <strong>in</strong>dividual bas<strong>is</strong>.<br />

Based on compar<strong>is</strong>on between survey results and INAMI data sources on allogenous<br />

BMT, we estimated that 33% of all allogenous SCT (children and adult confounded)<br />

receive IG supplementation.<br />

<strong>The</strong> dosage used <strong>in</strong> Belgium ranges 0.2-0.5g/kg, <strong>with</strong> the majority of centres us<strong>in</strong>g<br />

0.4g/kg. In the Netherlands, treatment scheme was 0.5g/kg per week (before transplant)<br />

then followed by 0.5g/kg per month as ma<strong>in</strong>tenance dose; <strong>in</strong> France, 0.4-0.6g/kg as<br />

load<strong>in</strong>g dose followed by 0.3g/kg. In most studies, IG prophylax<strong>is</strong> was given for 3<br />

months and the maximum period of adm<strong>in</strong><strong>is</strong>tration was 1 year. Most guidel<strong>in</strong>es<br />

recommend cont<strong>in</strong>u<strong>in</strong>g IG after transplant until reconstitution of B cell and antibody<br />

production has been achieved. We estimated that IG treatments were adm<strong>in</strong><strong>is</strong>tered <strong>in</strong><br />

average 12 times per year, based on the survey results (10.8 <strong>in</strong> children and 12 <strong>in</strong><br />

adults).<br />

Guilla<strong>in</strong>-Barré Syndrome (GBS)<br />

Five epidemiological studies, conducted <strong>in</strong> the period 1992-2000 <strong>in</strong> the UK, Italy (2<br />

studies), Spa<strong>in</strong> and Sweden were selected for the estimation of <strong>in</strong>cidence rate. 164,165,166,167,<br />

168<br />

A German study based on hospital records has been excluded as the methods did<br />

not <strong>in</strong>clude validation of diagnos<strong>is</strong>; 169 <strong>in</strong>deed, such studies were shown to over-estimate<br />

d<strong>is</strong>ease <strong>in</strong>cidence. 167 Most studies <strong>report</strong>ed similar values, suggest<strong>in</strong>g that GBS occur<br />

evenly, at least throughout the Western hem<strong>is</strong>phere: the <strong>in</strong>cidence rate ranged 1.26-<br />

1.63 per 100,000 <strong>in</strong> the five studies, and the weighted average <strong>is</strong> 1.42 per 100,000.<br />

In four studies conducted <strong>in</strong> Italy, Spa<strong>in</strong> and Sweden (two studies) <strong>in</strong> the period 1996-<br />

1999 and <strong>in</strong>volv<strong>in</strong>g a total of 343 cases, the proportion of GBS cases treated <strong>with</strong> IG<br />

165, 166, 170, 171<br />

ranged 65-82% <strong>with</strong> a weighted average at 75%.<br />

<strong>The</strong> dosage was 2 g/kg per treatment <strong>in</strong> all studies and reviews. Only one Dutch<br />

publication described the proportion of cases requir<strong>in</strong>g a second treatment from two<br />

studies, which amounted at 7% of the GBS cases <strong>in</strong>itially treated. 172<br />

Chronic <strong>in</strong>flammatory demyel<strong>in</strong>at<strong>in</strong>g polyneuropathy (CIDP)<br />

Two EU studies (Italy and England) and an Australian study calculated the CIDP<br />

prevalence, which ranged 1.9-3.6. 173,174,175 <strong>The</strong>se differences are expla<strong>in</strong>ed by a lack of<br />

diagnostic gold standard or clear diagnostic criteria. <strong>The</strong> weighted averaged <strong>in</strong>cidence<br />

rate was calculated at 2.7 per 100,000.<br />

<strong>The</strong> proportion of all CIDP cases that were treated <strong>with</strong> long term IG were estimated<br />

<strong>in</strong> 3 studies from France (2 studies) and the UK, publ<strong>is</strong>hed <strong>in</strong> 2007-2008, and ranged 51-<br />

63%. 175 , 176 , 177 <strong>The</strong> weighted average was 56%.<br />

<strong>The</strong> dosage ranged 0.4-2g/kg <strong>in</strong> studies and national recommendations. In Belgium, the<br />

maximum reimbursed dose ranges 0.25-2g/kg <strong>with</strong> a maximum of 9g/kg/6 months. <strong>The</strong><br />

practice for CIDP (and MMN) <strong>is</strong> to start at 2g/kg dose and rapidly decrease the dose<br />

accord<strong>in</strong>g to the cl<strong>in</strong>ical response, to reach a m<strong>in</strong>imal ma<strong>in</strong>tenance dose; it has been<br />

estimated at 1.5g/kg <strong>in</strong> average. <strong>The</strong> median <strong>in</strong>terval for IVIG adm<strong>in</strong><strong>is</strong>tration <strong>in</strong> studies<br />

was 3 weeks (frequency of 17.3 per year).

Multifocal motor neuropathy (MMN)<br />

Epidemiological data on MMN prevalence are scarce: only two EU prevalence studies<br />

from England and the Netherlands were found <strong>in</strong> conference abstracts, <strong>with</strong> very similar<br />

values. 178 <strong>The</strong> average could not be weighted for study size as the number of cases was<br />

m<strong>is</strong>s<strong>in</strong>g <strong>in</strong> the Engl<strong>is</strong>h study. <strong>The</strong> 2008 prevalence was respectively 0.53 and 0.58 per<br />

100,000 <strong>in</strong> England and the Netherlands, and the average <strong>in</strong>cidence rate calculated at<br />

0.56 per 100,000.<br />

Data on the proportion of all MMN cases that were treated <strong>with</strong> IG were found <strong>in</strong> 3<br />

recent EU studies, conducted <strong>in</strong> the UK, the Netherlands and France and publ<strong>is</strong>hed <strong>in</strong><br />

2007-2008. 179,178,180 Th<strong>is</strong> proportion ranged 51-76% and the weighted average was 66%.<br />

<strong>The</strong> dosage was 2 g/kg per treatment <strong>in</strong> all studies, though the maximum reimbursed <strong>in</strong><br />

Belgium ranges 0.25-2g/kg <strong>with</strong> a maximum of 9g/kg/6 months. <strong>The</strong> median <strong>in</strong>terval for<br />

IVIG adm<strong>in</strong><strong>is</strong>tration <strong>in</strong> studies was 3 weeks (frequency of 17.3 per year). However, the<br />

annual IG amount used to treat one case widely varied across studies, rang<strong>in</strong>g 248g <strong>in</strong><br />

New Zealand to 1728g <strong>in</strong> the UK. 149,179<br />

Multiple scleros<strong>is</strong> (MS)<br />

Several epidemiological studies on MS prevalence <strong>in</strong> Europe were found but showed<br />

very diverg<strong>in</strong>g values. Due to an observed North-South gradient <strong>in</strong> prevalence, our<br />

analys<strong>is</strong> was limited to countries or regions hav<strong>in</strong>g a latitude similar to Belgium and a<br />

population of >2 millions <strong>in</strong>habitants to decrease the <strong>in</strong>accuracies due to small numbers<br />

of cases. Only studies us<strong>in</strong>g the Poser criteria for MS diagnos<strong>is</strong> and validation of<br />

diagnos<strong>is</strong> were selected. Studies based on community surveys and self <strong>report</strong>ed cases<br />

were excluded.<br />

A survey was conducted <strong>in</strong> Flanders <strong>in</strong> 1991 but was excluded as it did not fit <strong>in</strong><br />

<strong>in</strong>clusion period. 181 Indeed prevalence <strong>is</strong> <strong>in</strong>creas<strong>in</strong>g over time, likely due to improved<br />

diagnos<strong>is</strong> and unknown factors. <strong>The</strong> two selected studies were conducted <strong>in</strong> France and<br />

Austria and the prevalence for def<strong>in</strong>ite and probable cases was 120 and 99 per 100,000<br />

respectively, <strong>with</strong> a weighted average at 103 per 100,000. 182,183<br />

Immunoglobul<strong>in</strong>s may be used for very specific MS cases, i.e. <strong>in</strong> cases of relapses that<br />

are res<strong>is</strong>tant to other treatment, when other therapies are not tolerated, as well as <strong>in</strong><br />

the post-partum for the prevention of relapses. No studies were found on the<br />

proportion of MS patients that are treated <strong>with</strong> IG. Experts estimate that 0-3% of MS<br />

patients are treated <strong>with</strong> IG for treatment (or prevention) of relapses. Consider<strong>in</strong>g that<br />

IG are mostly used for the prevention of post-partum relapses, that women <strong>in</strong> postpartum<br />

represent 1.1% of the Belgian population and that a large European prospective<br />

study estimated that 28% of pregnant women experience a relapse <strong>in</strong> the 3 months<br />

post-partum, we can assume that a maximum 0.31% of MS cases could benefit from<br />

IG. 184 IG <strong>is</strong> not reimbursed <strong>in</strong> Belgium for th<strong>is</strong> d<strong>is</strong>ease but some private <strong>in</strong>surance might<br />

reimburse it.<br />

<strong>The</strong> doses used ranged 0.15-2g/kg/month, <strong>with</strong> no superiority of a given dose shown.<br />

An observational Austrian study among pregnant women calculated that an average<br />

dose of 0.24 g/kg/month was given. 85 <strong>The</strong> mean treatment duration was 3.4 +/- 1.8 years<br />

and the mean time to first relapse <strong>with</strong> IG therapy was 247 days (median 199 days) <strong>in</strong><br />

the first 2 years.<br />

Myasthenia grav<strong>is</strong><br />

Studies on myasthenia grav<strong>is</strong> (MG) prevalence showed very different values, depend<strong>in</strong>g<br />

on the diagnostic criteria. Three studies conducted <strong>in</strong> Sweden, the Netherlands and<br />

England <strong>in</strong> 1997-1999 estimated a prevalence rang<strong>in</strong>g 11.9-14.1 per 100,000. 105 , 185 , 186 A<br />

study <strong>in</strong> Greece was excluded because MG cases were limited to those hav<strong>in</strong>g<br />

antibodies aga<strong>in</strong>st the acetylchol<strong>in</strong>e receptor, which represented only 79% of total cases<br />

<strong>in</strong> both the Dutch and the Engl<strong>is</strong>h studies. <strong>The</strong> weighted average of the three selected<br />

studies was 12.7 per 100,000. However, th<strong>is</strong> estimate probably underestimates the<br />

current figure as prevalence <strong>in</strong>creases over the years, due to the age<strong>in</strong>g of population<br />

comb<strong>in</strong>ed to a higher prevalence found among the elderly.


92 Plasma <strong>KCE</strong> Reports 120<br />

<strong>The</strong> proportion of MG cases treated <strong>with</strong> long term IG was not found. <strong>The</strong> 1997 Engl<strong>is</strong>h<br />

study described 3% patients be<strong>in</strong>g under plasma exchange therapy (the golden standard<br />

for myasthenic cr<strong>is</strong><strong>is</strong> at that time). 185 S<strong>in</strong>ce th<strong>is</strong> therapy has often been replaced by IG <strong>in</strong><br />

recent years, we estimated that 3% MG patient would be treated <strong>with</strong> IG, and experts<br />

considered th<strong>is</strong> estimate to be valid for the Belgian situation.<br />

<strong>The</strong> dosage was 2g/kg <strong>in</strong> most studies and national recommendations, but a study<br />

compar<strong>in</strong>g a dose of 1g vs. 2g/kg body weight suggested that 1g/kg may be sufficient.<br />

<strong>The</strong>re <strong>is</strong> no evidence to support IG use as a long-term treatment, thus a s<strong>in</strong>gle<br />

treatment <strong>in</strong> case of cr<strong>is</strong><strong>is</strong> or exacerbations was assumed.<br />

Dermatomyosit<strong>is</strong> and polymyosit<strong>is</strong><br />

Dermatomyosit<strong>is</strong> and polymyosit<strong>is</strong> cases were not d<strong>is</strong>t<strong>in</strong>gu<strong>is</strong>hed as both d<strong>is</strong>eases are<br />

idiopathic <strong>in</strong>flammatory myopathies, usually studied together. Only one recent study<br />

estimat<strong>in</strong>g the prevalence of dermatomyosit<strong>is</strong> and polymyosit<strong>is</strong> was identified,<br />

conducted <strong>in</strong> Canada <strong>in</strong> a population of 7.5 million <strong>in</strong>habitants, and found a 2003<br />

prevalence at 21.5/100,000. 187 Older estimates from the USA and Japan ranged 5.0-6.3<br />

per 100,000 <strong>in</strong> 1960-1987 but are considered to underestimate the true d<strong>is</strong>ease<br />

prevalence. 188<br />

Data on the proportion of dermatomyosit<strong>is</strong> patients treated was only found <strong>in</strong> an older<br />

cohort study on juvenile dermatomyosit<strong>is</strong> <strong>in</strong> Canada, represent<strong>in</strong>g 9% of cases, and<br />

cannot be used to extrapolate to other age groups. 189 ) It <strong>is</strong> only known that IG <strong>is</strong> only<br />

needed <strong>in</strong> special cases and seems the treatment of choice <strong>in</strong> severe myosit<strong>is</strong> <strong>with</strong><br />

dysphagia. 190<br />

<strong>The</strong> dosage was 2g/kg every 3-6 weeks <strong>in</strong> most studies. Data on practice <strong>in</strong> Belgium<br />

have not been found. In the 15 patients <strong>in</strong>cluded <strong>in</strong> the only RCT conducted so far, the<br />

frequency of treatment varied from every 3 to 6 weeks (average 4 weeks) and two<br />

patients could stop IG treatment. 110<br />

As no data are <strong>available</strong> on the proportion of cases treated, th<strong>is</strong> d<strong>is</strong>ease has not been<br />

<strong>in</strong>cluded <strong>in</strong> the calculation. However, as we know that the treatment of<br />

dermatomyosit<strong>is</strong> cases represented 2% of total amount of IG used <strong>in</strong> the three studies<br />

<strong>in</strong> other countries (Table 22), the same proportion of the total IG amount has been<br />

assumed <strong>in</strong> Belgium.<br />

Kawasaki d<strong>is</strong>ease<br />

<strong>The</strong> <strong>in</strong>cidence of Kawasaki d<strong>is</strong>ease (KD) was estimated <strong>in</strong> Denmark, Sweden and New<br />

KD. 191,192,193 Incidence among children


<strong>KCE</strong> Reports 120 Plasma 93<br />

Based on these methods and the assumptions described under table 40, we have<br />

estimated that 576 kg (method A) and 483 kg (method B) of IG would be annually<br />

needed to treat these 11 d<strong>is</strong>eases, thus not <strong>in</strong>clud<strong>in</strong>g CLL. Th<strong>is</strong> would represent<br />

respectively 70% (A) and 59% (B) of the IG amount reimbursed <strong>in</strong> 2006 based on<br />

INAMI/RIZIV data (Table 41).<br />

Though we have not used stat<strong>is</strong>tical tests given the high <strong>in</strong>tr<strong>in</strong>sic uncerta<strong>in</strong>ty around<br />

some estimates and assumptions, the proportion of total IG use that would be required<br />

to treat these 11 d<strong>is</strong>eases <strong>is</strong> lower than calculated <strong>in</strong> the 4 studies, for both methods A<br />

and B: these 11 d<strong>is</strong>eases consumed 75%, 68%, 88% and 72% of the total IG amount <strong>in</strong><br />

New Zealand, Toronto (Canada), Massachusset (US) and the Canadian Atlantic<br />

prov<strong>in</strong>ces, <strong>with</strong> a weighted average of 74%. If we compare our estimates to the annual<br />

IG amount <strong>report</strong>ed by Belgian hospitals <strong>in</strong> 2008 (919.6 kg, <strong>KCE</strong> survey), th<strong>is</strong><br />

proportion would be even lower, represent<strong>in</strong>g 63% (A) and 53% (B) of total amount.<br />

Our estimation suggests that a higher proportion of IG <strong>is</strong> used for other <strong>in</strong>dications<br />

than those <strong>in</strong>cluded here, compared to other countries. In other studies, 12% to 32% of<br />

total IG amounts was consumed by the rema<strong>in</strong><strong>in</strong>g <strong>in</strong>dications, while th<strong>is</strong> would<br />

represent as much as 37% (A) and 41% (B) <strong>in</strong> Belgium. Th<strong>is</strong> <strong>is</strong> not surpr<strong>is</strong><strong>in</strong>g when we<br />

observed that, <strong>in</strong> Belgium, already 16% of IG has been prescribed by lung special<strong>is</strong>ts <strong>in</strong><br />

2008.<br />

However conclusions on the yearly amount of IG required <strong>in</strong> Belgium cannot be based<br />

on th<strong>is</strong> exerc<strong>is</strong>e, as th<strong>is</strong> estimation has many methodological limitations.<br />

3.3.3.4 Limitations<br />

<strong>The</strong> ma<strong>in</strong> limitations to th<strong>is</strong> estimation that we have identified are:<br />

• Th<strong>is</strong> method has probably underestimated the number of cases under IG<br />

treatment for several d<strong>is</strong>eases: First, our calculations were based on data<br />

from scientific studies, where all cases were verified for adherence <strong>with</strong><br />

def<strong>in</strong>ed case def<strong>in</strong>ition and criteria; <strong>in</strong> a real life sett<strong>in</strong>g, many more cases<br />

are likely to be treated. For <strong>in</strong>stance, we estimated that 150 cases of<br />

Guillla<strong>in</strong> Barré occur every year <strong>in</strong> Belgium, based on <strong>in</strong>cidence from<br />

neighbour<strong>in</strong>g countries, while RCM/MKG data for code ICD9CM 357-0 <strong>in</strong><br />

2000-2007 show annual numbers rang<strong>in</strong>g 609-717 cases. Second, many<br />

studies were based on old data from the n<strong>in</strong>eties and probably<br />

underestimated d<strong>is</strong>ease rate as the prevalence of several d<strong>is</strong>eases <strong>is</strong><br />

known to <strong>in</strong>crease <strong>with</strong> time, due to population age<strong>in</strong>g and improved<br />

diagnostic.<br />

• Th<strong>is</strong> estimation could not <strong>in</strong>clude cases of CLL.<br />

• We have found several other <strong>in</strong>cons<strong>is</strong>tencies when compar<strong>in</strong>g our<br />

estimates to other Belgian data, which may be due to the assumptions<br />

used or the lack of representativeness of practices <strong>in</strong> the centres<br />

surveyed. Th<strong>is</strong> was ma<strong>in</strong>ly observed for bone marrow transplant (BMT)<br />

where we likely underestimated the number of cases under treatment:<br />

the proportion of transplant cases treated <strong>with</strong> IG <strong>is</strong> based on data from<br />

two university hospitals and may be higher <strong>in</strong> other hospitals. Indeed, 56<br />

transplant cases under treatment were <strong>report</strong>ed <strong>in</strong> the survey from 4<br />

paediatric wards and an adult ward, while our overall estimate of BMT<br />

treated <strong>with</strong> IG <strong>in</strong> the whole Belgium <strong>is</strong> 105. Th<strong>is</strong> was also suggested by<br />

the lower proportion of total IG amount used <strong>in</strong> BMT <strong>in</strong> Belgium<br />

compared to other studies (3-4% vs. 11%). <strong>The</strong> number of ITP cases<br />

under IG treatment extrapolated from <strong>in</strong>cidence rates from other studies<br />

did not correspond to the number <strong>report</strong>ed by Belgian centres (52 cases<br />

under treatment are <strong>report</strong>ed from 5 university hospitals vs. 49 for all<br />

Belgium based on other studies).<br />

• Data on IG use are compared to four studies from three non-European<br />

countries (US, Canada, New Zealand), where IG use was <strong>report</strong>ed to be<br />

high.


94 Plasma <strong>KCE</strong> Reports 120<br />

• Many estimates were based on the Belgian survey and expert meet<strong>in</strong>gs,<br />

which may not be representative of the overall Belgian situation.<br />

In spite of the limitations due to th<strong>is</strong> method, we reach the same overall conclusions<br />

than the studies based on real IG consumption: the highest IG use <strong>is</strong> observed for<br />

immuno-haematological d<strong>is</strong>orders (41-43% of IG amount) but covers as much as 1545<br />

cases, compared to neuro-muscular d<strong>is</strong>eases which may consume 25-28% of total IG<br />

amount but only covers 367 cases. <strong>The</strong> d<strong>is</strong>eases likely to consume the highest amount<br />

of IG are: primary immune deficiencies, CIDP, MM, ITP and MMN.<br />

Key po<strong>in</strong>ts<br />

• Based on theoretical needs and assumptions, we estimated that from 483 to<br />

576 kg of IG would be annually needed to treat the 11 <strong>in</strong>dications consum<strong>in</strong>g<br />

the highest amount of IG <strong>in</strong> Belgium, exclud<strong>in</strong>g CLL. Th<strong>is</strong> would represent<br />

53-63% of the total IG amount prescribed <strong>in</strong> Belgium <strong>in</strong> 2008. Compared to<br />

studies from other countries (Canada, New Zealand and the US), th<strong>is</strong><br />

represents a lower proportion of the total IG amount to treat these<br />

d<strong>is</strong>eases.<br />

• Th<strong>is</strong> compar<strong>is</strong>on suggests that <strong>in</strong> Belgium, a higher proportion of IG <strong>is</strong> used<br />

to treat the rema<strong>in</strong><strong>in</strong>g <strong>in</strong>dications (37-41% <strong>in</strong> Belgium vs. 12-32% <strong>in</strong> the other<br />

countries). Part of th<strong>is</strong> difference may be expla<strong>in</strong>ed by the 16% of total IG<br />

that has been prescribed by lung special<strong>is</strong>ts <strong>in</strong> 2008.<br />

• However conclusions on the yearly amount of IG required <strong>in</strong> Belgium cannot<br />

be based on th<strong>is</strong> exerc<strong>is</strong>e, as th<strong>is</strong> estimation has many methodological<br />

limitations and probably underestimates the amount that would be required<br />

<strong>in</strong> a “real life” sett<strong>in</strong>g.

3.3.4 Expected trends <strong>in</strong> consumption<br />

We have identified a few trends and scientific progresses that may <strong>in</strong>fluence future<br />

trends <strong>in</strong> IG use and consumption, to help predict future trends.<br />

1. <strong>The</strong> number of allogenic bone marrow transplants performed <strong>in</strong> Belgium <strong>is</strong><br />

<strong>in</strong>creas<strong>in</strong>g from year to year, from 216 <strong>in</strong> 2005 to 284 <strong>in</strong> 2007 (+31% <strong>in</strong> 2<br />

years). In Europe, a study estimated a more conservative 13% r<strong>is</strong>e <strong>in</strong> bone<br />

marrow transplants to be expected from 2005 to 2010. 194 Th<strong>is</strong> would imply<br />

an <strong>in</strong>creased IG use over time. However, the <strong>in</strong>crease <strong>in</strong> non-myeloablative<br />

transplants <strong>in</strong> adults, <strong>with</strong> a consequent lower level and shorter duration of<br />

hypogammaglobul<strong>in</strong>emia, would tend to decrease IG needs.<br />

2. <strong>The</strong> prognos<strong>is</strong> of patients <strong>with</strong> MM has improved significantly dur<strong>in</strong>g the last<br />

three decades, result<strong>in</strong>g <strong>in</strong> <strong>in</strong>creased survival. 195 Th<strong>is</strong> will likely <strong>in</strong>crease the<br />

d<strong>is</strong>ease prevalence and related needs <strong>in</strong> IG. But alternative therapies for MM<br />

and CLL are also <strong>in</strong>creas<strong>in</strong>gly used and th<strong>is</strong> may result <strong>in</strong> decreased needs <strong>in</strong><br />

IG supplementation.<br />

3. <strong>The</strong> prevalence of multiple scleros<strong>is</strong> and myasthenia grav<strong>is</strong> <strong>is</strong> <strong>in</strong>creas<strong>in</strong>g <strong>with</strong><br />

time, due to age<strong>in</strong>g of the population and better diagnostic tools, and could<br />

result <strong>in</strong> <strong>in</strong>creas<strong>in</strong>g IG needs.<br />

4. Alternative treatments for ITP and for the prevention of <strong>in</strong>fections <strong>in</strong><br />

transplant are under development. Some therapies are arriv<strong>in</strong>g on the market<br />

(e.g. Rituximab and Romiplost<strong>in</strong>e) could potentially decrease IG use for these<br />

<strong>in</strong>dications.<br />

5. Many studies are conducted to test alternative treatment that would allow<br />

decreas<strong>in</strong>g or even stopp<strong>in</strong>g IG ma<strong>in</strong>tenance treatment <strong>in</strong> CIDP cases. If<br />

successful and <strong>available</strong>, these therapies would decrease IG use for th<strong>is</strong><br />

d<strong>is</strong>ease.<br />

6. Alzheimer d<strong>is</strong>ease, any auto-immune d<strong>is</strong>ease, asthma and some other<br />

frequent d<strong>is</strong>eases related to immunity and for which no alternative treatment<br />

has shown efficacy, may be considered by some physicians as new <strong>in</strong>dications<br />

for IG. Th<strong>is</strong> may represent a problem before any RCT could demonstrate the<br />

efficacy - or lack of efficacy - of IG for these d<strong>is</strong>eases.

4.1 WHAT ARE THE RISKS AT WORLDWIDE LEVEL ?<br />

4.1.1 Plasma collection: Key role of the North American Region<br />

Over the last years, total volume of plasma <strong>available</strong> worldwide for fractionation has<br />

slightly <strong>in</strong>creased (22.3 million litres <strong>in</strong> 2000, 21.4 million litres <strong>in</strong> 2005) and reached<br />

26.5 million litres <strong>in</strong> 2007, broken down as below:<br />

• 17.9 million of apherese plasma (9.2 million <strong>in</strong> 2000 ; 13.7 <strong>in</strong> 2005)<br />

• 8.6 million of recovered plasma (13.2 million <strong>in</strong> 2000 ; 7.7 <strong>in</strong> 2005)<br />

From a geographical po<strong>in</strong>t of view, North America clearly rema<strong>in</strong>s the key stakeholder<br />

<strong>in</strong> plasma collection. Conversely, one must bear <strong>in</strong> m<strong>in</strong>d that Europe rema<strong>in</strong>s the key<br />

stakeholder <strong>in</strong> the fractionation <strong>in</strong>dustry.<br />

As expla<strong>in</strong>ed above, more than 50% of plasma collected worldwide <strong>is</strong> collected <strong>in</strong> North<br />

America (ma<strong>in</strong>ly <strong>in</strong> the USA). Th<strong>is</strong> ration reaches 70% for apherese plasma.<br />

Plasma donation and collection <strong>in</strong> the USA (as well as blood donation and collection <strong>in</strong><br />

general) <strong>is</strong> based on purely private and commercial pr<strong>in</strong>ciples. Donor selection <strong>is</strong><br />

organized on a r<strong>is</strong>k-management bas<strong>is</strong>, and blood donation <strong>is</strong> paid. Th<strong>is</strong> ethical and<br />

organ<strong>is</strong>ational framework <strong>is</strong> largely different from the European one.<br />

In practice, a large part of the plasma collected <strong>in</strong> the United States needs to be<br />

exported to Europe <strong>in</strong> order to be processed, and re-imported <strong>in</strong>to the United States<br />

for cl<strong>in</strong>ical use. <strong>The</strong>refore, it <strong>is</strong> also of paramount importance to underl<strong>in</strong>e that Europebased<br />

fractionation facilities are often devoted to the supply of the world market,<br />

especially the American one. In other words, European fractionation capacity <strong>is</strong> largely<br />

devoted to the needs of non European (especially US) patients.<br />

In order to fulfil the American patients’ needs, it <strong>is</strong> vital for American stakeholders to<br />

secure the supply of plasma products, the latter be<strong>in</strong>g largely produced by Europe-based<br />

companies. Th<strong>is</strong> may lead American stakeholders to implement specific corporate<br />

strategies (especially long term supply contracts) or even purchase strategies <strong>in</strong> Europe.<br />

For obvious reasons, these strategies are implemented, <strong>with</strong> a view to improv<strong>in</strong>g the<br />

American patients (whatever the needs of the European patients may be).<br />

Should a shortage of plasma products appear (eg sharp and quick ra<strong>is</strong>e <strong>in</strong> global needs<br />

due to new <strong>in</strong>dications), potential competition between American patients’ needs and<br />

European patients’ needs could be clearly identified.<br />

Moreover, as mentioned below, any change <strong>in</strong> the use of plasma products, especially<br />

<strong>in</strong>dications <strong>in</strong> the USA (or even changes <strong>in</strong> prescription habits) <strong>is</strong> likely to have an<br />

impact on the US demand and then <strong>in</strong>directly on the European fractionation <strong>in</strong>dustry.<br />

Basically, consider<strong>in</strong>g today’s situation of American and European plasma fractionation<br />

<strong>in</strong>dustry, the ma<strong>in</strong> concern of American stakeholders <strong>is</strong> to secure the stream of plasma<br />

products across the Atlantic. As a practical matter, if US health authorities decided to<br />

restrict export of their own raw plasma, European countries would not be <strong>in</strong> the<br />

position to fulfil immediately the needs of European patients.

Indications have evolved over the last years. <strong>The</strong>refore, it <strong>is</strong> important to stress that<br />

these evolutions have had an impact (or even a major) on the demand of plasma<br />

products. It rema<strong>in</strong>s difficult to forecast evolution of consumption prec<strong>is</strong>ely, as different<br />

factors must be taken <strong>in</strong>to account: research progress and new evidence-based<br />

<strong>in</strong>dications, but also d<strong>is</strong>sem<strong>in</strong>ation of premature and non evidence-based practices or<br />

expert op<strong>in</strong>ions.<br />

• <strong>The</strong> North American region (especially the United States) rema<strong>in</strong>s the<br />

“World’s plasma collector” whereas Europe rema<strong>in</strong>s the “World’s plasma<br />

fractionator”.<br />

• <strong>The</strong> ma<strong>in</strong> concern of the American stakeholders <strong>is</strong> to secure the supply for<br />

plasma products, by different means (long term supply contracts, control of<br />

fractionation capacities), whereas the fulfill<strong>in</strong>g of European patients<br />

simultaneously requires large imports of American plasma.<br />

• Should US health authorities decide to restrict export of their own raw<br />

plasma, European patients would be put <strong>in</strong> a predicament. Any change of<br />

American practices (new <strong>in</strong>dications or change <strong>in</strong> prescription habits) must<br />

be kept under close scrut<strong>in</strong>y as it could lead to a similar deadlock.<br />

Conversely, American patients need to rely on the EU fractionation <strong>in</strong>dustry<br />

to fulfil their own needs.<br />

• Emerg<strong>in</strong>g countries are likely to play an ever greater role on the world<br />

market, which means greater competition between purchasers.<br />

4.2 CONCEPT OF SELF SUFFICIENCY<br />

4.2.1 In Belgium<br />

Belgian regulations do not def<strong>in</strong>e the proportion of plasma derivatives that must be<br />

produced <strong>in</strong> Belgium to m<strong>in</strong>im<strong>is</strong>e the r<strong>is</strong>k of shortages of plasma derivatives. A Royal<br />

Decree of 18 June 1998 simply states that <strong>in</strong> order to ensure self-sufficiency and the<br />

quality of the supplies of stable blood products of human orig<strong>in</strong>, the price of a litre of<br />

plasma, manufactured by plasmapheres<strong>is</strong> and sold by the Red Cross to the CAF-DCF,<br />

will be subsid<strong>is</strong>ed and that a firm of auditors will communicate each year to the SPF the<br />

number of litres sold <strong>in</strong> order to calculate correctly the subsidy.<br />

S<strong>in</strong>ce the quantity guarantee<strong>in</strong>g self-sufficiency <strong>is</strong> not explicitly stated <strong>in</strong> the decree, it<br />

transpires from verbal explanations gathered that the auditor i deems that self-sufficiency<br />

<strong>is</strong> achieved if the CAF-DCF provides<br />

• “a level of production cover<strong>in</strong>g 60% of the average national consumption<br />

of the ma<strong>in</strong> plasma-derived products – i.e. Factor VIII, Album<strong>in</strong>, and IVIG -<br />

<strong>in</strong> normal sanitary and epidemiological conditions, and consider<strong>in</strong>g<br />

approved <strong>in</strong>dications”<br />

• “a quarant<strong>in</strong>e stock cover<strong>in</strong>g 90 days of average national consumption for<br />

the three ma<strong>in</strong> products mentioned above”. In practice, th<strong>is</strong> stock<br />

compr<strong>is</strong>es 8000 bottles of Album<strong>in</strong>, 1 million doses of Factor VIII, and<br />

50kg of IVIG.<br />

Th<strong>is</strong> quantity <strong>is</strong> shown on the first l<strong>in</strong>e of the table below. PWC then deducts from th<strong>is</strong><br />

quantity the number of litres of non-subsid<strong>is</strong>ed plasma (RP) (l<strong>in</strong>e 2) and adds to it the<br />

number of litres taken from stocks (l<strong>in</strong>e 4) to calculate the number of litres to be<br />

subsid<strong>is</strong>ed (l<strong>in</strong>e 5).<br />

i Th<strong>is</strong> role <strong>is</strong> assumed by the firm PricewaterhouseCoopers. See ‘Plasma from plasmapheres<strong>is</strong> required for<br />

self-sufficiency <strong>in</strong> Belgium <strong>in</strong> 2008’ PWC

But these quantities are approximately the same than the collected quantities except for<br />

2006. We didn’t receive any explanation for th<strong>is</strong> difference of 2.237 litres (i.e. 3.9% of<br />

the total volume of SP collected <strong>in</strong> 2006).<br />

It clearly emerges that the term self-sufficiency <strong>is</strong> no longer adequate to describe the<br />

data from these calculations. PWC starts <strong>with</strong> a total quantity of plasma, which <strong>is</strong> the<br />

quantity that the CAF-DCF would have to buy to supply a quantity of derivatives over<br />

and above those supplied by commercial firms <strong>in</strong> Belgium. It <strong>is</strong> important to understand<br />

that the total market for plasma derivatives <strong>is</strong> not divided between the ex<strong>is</strong>t<strong>in</strong>g vendors<br />

<strong>in</strong> a fixed d<strong>is</strong>tribution pattern. It <strong>is</strong> the <strong>in</strong>terplay of competition that determ<strong>in</strong>es the<br />

quantities that the CAF-DCF and the other foreign commercial vendors will sell dur<strong>in</strong>g<br />

a given year to the various hospitals. Th<strong>is</strong> clearly establ<strong>is</strong>hes that self-sufficiency only<br />

relates to a part of Belgian consumption, which results from competition between the<br />

firms operat<strong>in</strong>g <strong>in</strong> the market.<br />

It appears that the authority has no clear <strong>in</strong>tention of achiev<strong>in</strong>g total <strong>in</strong>dependence. But<br />

does the coverage of 60%, extended to 180 days, which seems somewhat arbitrary,<br />

truly reflect a reasonable r<strong>is</strong>k? Nobody knows. We also f<strong>in</strong>d no scientific justification for<br />

the quarant<strong>in</strong>e period (dur<strong>in</strong>g which the plasma must be kept before fractionation).<br />

Th<strong>is</strong> was extended from 50 to 180 days between 1998 and 2006 <strong>with</strong> no justification for<br />

th<strong>is</strong> extension from the standpo<strong>in</strong>t of medical safety. It therefore appears that the<br />

concepts of self-sufficiency and quarant<strong>in</strong>e have never been properly considered and<br />

def<strong>in</strong>ed <strong>in</strong> Belgium.

4.2.2.1 In Australia<br />

Australian official def<strong>in</strong>ition of Self-sufficiency<br />

<strong>The</strong> promotion of national self-sufficiency <strong>in</strong> respect of blood and blood products <strong>is</strong> a<br />

policy aim of Australia’s Commonwealth, state and territory governments. <strong>The</strong><br />

Australian Health M<strong>in</strong><strong>is</strong>ters’ Conference Policy Statement on National Self Sufficiency <strong>in</strong><br />

the Supply of Blood and Blood Products, <strong>is</strong>sued <strong>in</strong> April 2006 196 , def<strong>in</strong>es self-sufficiency<br />

as: “Australia striv<strong>in</strong>g to source blood components and plasma from <strong>with</strong><strong>in</strong> Australia to<br />

meet appropriate cl<strong>in</strong>ical demand”.<br />

Self-Sufficiency objective and National Blood Agreement<br />

All Australian, State and Territory Governments are signatories to the National Blood<br />

Agreement 2003, which sets out, the policy objectives and aims for Australia’s national<br />

blood sector, which are:<br />

• provide an adequate, safe, secure and affordable supply of blood<br />

products,blood related products and blood related services;<br />

• promote safe, high quality management and use of blood products, blood<br />

related products and blood related services <strong>in</strong> Australia.<br />

<strong>The</strong>refore all stakeholders are clearly committed <strong>in</strong> the field implementation of selfsufficiency<br />

policy.<br />

However, national self-sufficiency objective does not preclude Australia from import<strong>in</strong>g<br />

blood or plasma products <strong>in</strong> a narrow range of circumstances, ie where there <strong>is</strong> an<br />

<strong>in</strong>ability to meet cl<strong>in</strong>ical needs through the domestic supply, and where supply cha<strong>in</strong><br />

r<strong>is</strong>ks must be addressed. <strong>The</strong> Australian Health M<strong>in</strong><strong>is</strong>ters’ Conference statement<br />

acknowledged that Australia <strong>is</strong> (and has never been) not totally self-sufficient <strong>in</strong> plasma<br />

products and derivatives.<br />

<strong>The</strong>refore the agreement signed between health authorities and CSL-Limited also gave<br />

room for some flexibility on the matter of import of plasma products and derivatives,<br />

<strong>with</strong><strong>in</strong> a strict framework that:<br />

• ensures adequacy of supply to Australian patients <strong>in</strong> need;<br />

• m<strong>in</strong>imizes the supply security and product safety r<strong>is</strong>ks to patients;<br />

• ensures affordability of products to the Australian health sector; and<br />

• recognizes the practicalities of production and d<strong>is</strong>tribution.<br />

Self sufficiency and Australian national blood policy<br />

<strong>The</strong> Australian example has been selected, s<strong>in</strong>ce Australia <strong>is</strong> the only western country<br />

that has succeeded <strong>in</strong> sett<strong>in</strong>g up a comprehensive blood and plasma policy, from a<br />

• practical po<strong>in</strong>t of view : organization of donation, collection, fractionation<br />

of blood and plasma<br />

• legal po<strong>in</strong>t of view : strong <strong>in</strong>terface between suppliers and health<br />

authorities<br />

• cl<strong>in</strong>ical po<strong>in</strong>t of view : <strong>in</strong>terface between cl<strong>in</strong>ical practices and supply<br />

policy.


104 Plasma <strong>KCE</strong> Reports 120<br />

It must be outl<strong>in</strong>ed that such a policy requires an unfail<strong>in</strong>g and long-last<strong>in</strong>g political<br />

commitment of the national health authorities. In Australia th<strong>is</strong> policy th<strong>is</strong> policy has<br />

been <strong>in</strong>itiated <strong>in</strong> the fifties: the Commonwealth Serum Laboratories (hereafter “CSL”)<br />

orig<strong>in</strong>ally founded <strong>in</strong> 1916 commenced production of fractionated products <strong>in</strong> 1953,<br />

thanks to the Australian Government’s support. CSL was later privatized and merged<br />

<strong>with</strong> Behr<strong>in</strong>g.<br />

<strong>The</strong> Australian policy was elaborated step by step, and <strong>in</strong> 1995 the Commonwealth<br />

Review of the Australian Blood and Blood Product System identified the need for a<br />

s<strong>in</strong>gle, <strong>in</strong>tegrated, blood supply agency <strong>in</strong> Australia <strong>with</strong> a view to enhanc<strong>in</strong>g the safety,<br />

efficacy,and adequacy of supply of blood and blood products. As a result of that, the<br />

separate state and territory blood services comb<strong>in</strong>ed to form the Australian Red Cross<br />

Blood Service <strong>in</strong> 1996.<br />

<strong>The</strong> Review of the Australian Blood Bank<strong>in</strong>g and Plasma sector, which was completed <strong>in</strong><br />

2001, recommended the establ<strong>is</strong>hment of an authority to provide national management<br />

and oversight of Australia’s blood system. Follow<strong>in</strong>g th<strong>is</strong> review, the National Blood<br />

Authority (hereafter “NBA”) was set up <strong>in</strong> 2003.<br />

Background: Australian adm<strong>in</strong><strong>is</strong>trative structure<br />

ROLE OF THE NATIONAL BLOOD AUTHORITY<br />

Australian blood and blood products policy (especially <strong>in</strong> the field of plasma products)<br />

has been centralized and rationalized every angle: one s<strong>in</strong>gle public body <strong>is</strong> entrusted to<br />

manage the whole Australian policy. <strong>The</strong> National Blood Authority <strong>is</strong> a statutory and<br />

overarch<strong>in</strong>g agency establ<strong>is</strong>hed under the National Blood Authority Act 2003 . <strong>The</strong><br />

NBA <strong>is</strong> central to Australia’s national blood and plasma policy. <strong>The</strong> most important and<br />

<strong>in</strong>terest<strong>in</strong>g character<strong>is</strong>tic of the NBA <strong>is</strong> that it covers the whole scope of th<strong>is</strong> policy:<br />

• Coord<strong>in</strong>ation of demand and supply plann<strong>in</strong>g of blood and blood products<br />

and purchase those products on behalf of Health authorities<br />

• Negotiation and follow-up of the contracts <strong>with</strong> suppliers of blood, blood<br />

products and blood services, <strong>in</strong>clud<strong>in</strong>g development of a national pric<strong>in</strong>g<br />

schedule.<br />

• Implementation of an efficient blood use based on evidence-based<br />

pr<strong>in</strong>ciples and good cl<strong>in</strong>ical practice. (<strong>in</strong>cl. <strong>in</strong>formation and advice to<br />

governments ).<br />

• Coord<strong>in</strong>ation of the development of the National Health and Medical<br />

Research Council’s Cl<strong>in</strong>ical Practice Guidel<strong>in</strong>es for the Use of Blood<br />

Components.<br />

• Follow-up of legal <strong>is</strong>sues<br />

Further <strong>in</strong>formation <strong>is</strong> provided on <strong>in</strong>stitutional aspects (NBA and other <strong>in</strong>stitutions <strong>in</strong><br />

the appendix).<br />

Access to plasma derivatives: key po<strong>in</strong>ts<br />

APPROVAL PROCESS AS DESIGNED UNTIL MARCH 2008<br />

Access to plasma-derived products has been rationalized and must abide by a specific<br />

cl<strong>in</strong>ical and adm<strong>in</strong><strong>is</strong>trative process. Processes may vary across the Australian States<br />

(some of them be<strong>in</strong>g more demand<strong>in</strong>g or than others); however, the key po<strong>in</strong>t of the<br />

Australian policy <strong>is</strong> to rationalize the use of plasma derived products (especially IVIG<br />

which represents two-thirds of Australia’s demand <strong>in</strong> th<strong>is</strong> field) both for ethical reasons<br />

(optimal use of donated blood) but also for practical reasons (avoid<strong>in</strong>g shortage).<br />

From a purely cl<strong>in</strong>ical po<strong>in</strong>t of view <strong>in</strong>dications have been grouped <strong>in</strong>to three groups<br />

depend<strong>in</strong>g on the level of cl<strong>in</strong>ical accuracy:<br />

• Category 1: <strong>in</strong>dications for which strong evidence of IVIg benefit has been<br />

identified.<br />

• Category 2: <strong>in</strong>dications for which evidence of th<strong>is</strong> benefit <strong>is</strong> <strong>in</strong>conclusive<br />

for the follow<strong>in</strong>g reasons:


<strong>KCE</strong> Reports 120 Plasma 105<br />

• Conflict<strong>in</strong>g evidence<br />

• Low level of evidence<br />

• Little research, especially for rare conditions<br />

Category 3: <strong>in</strong>dications for which there <strong>is</strong> conv<strong>in</strong>c<strong>in</strong>g evidence that IVIg br<strong>in</strong>gs no<br />

benefit. A strong f<strong>in</strong>ancial connection has been establ<strong>is</strong>hed between accuracy of<br />

<strong>in</strong>dications – as described above – and fund<strong>in</strong>g policy. In short, prescription of Category<br />

1 IVIg <strong>is</strong> funded on the bas<strong>is</strong> of a specific cost-shar<strong>in</strong>g arrangement, called Australia’s<br />

National Blood Agreement ie 63% by the Australian Government (national level) and<br />

37% by the State / Territory level. Prescription of imported IVIg products outside of<br />

Category 1 are not co-funded, and IVIg products must be purchased at full price by<br />

prescribers (hospitals) directly from the relevant manufacturer which are responsible<br />

for production of IVIg. Hence, there <strong>is</strong> a f<strong>in</strong>ancial <strong>in</strong>centive for an evidence-based and<br />

rational use of IVIg products.<br />

<strong>The</strong> ARCBS approved requests that meet category 1. If <strong>in</strong>sufficient <strong>in</strong>formation was<br />

provided by the cl<strong>in</strong>ician to the ARCBS, the request was forwarded to the local IVIG<br />

Work<strong>in</strong>g Group. Th<strong>is</strong> IVIG Work<strong>in</strong>g Group cons<strong>is</strong>ted of 8 cl<strong>in</strong>icians, represent<strong>in</strong>g<br />

specialities who had an <strong>in</strong>terest <strong>in</strong> IVIG <strong>is</strong>sues, and made the f<strong>in</strong>al dec<strong>is</strong>ion (approval or<br />

not).<br />

In March 2008 (ongo<strong>in</strong>g reform), the new “Criteria for the cl<strong>in</strong>ical use of <strong>in</strong>travenous<br />

immunoglobul<strong>in</strong> <strong>in</strong> Australia” (hereafter “Criteria”) have been officially <strong>is</strong>sued by the<br />

Australian. In short, the conditions are categor<strong>is</strong>ed <strong>in</strong> the Criteria under those for<br />

which IVIG has:<br />

• An establ<strong>is</strong>hed therapeutic role<br />

• An emerg<strong>in</strong>g therapeutic role<br />

• A use <strong>in</strong> exceptional circumstances<br />

• Conditions for which IVIG <strong>is</strong> not <strong>in</strong>dicated<br />

Supply contracts <strong>with</strong> CSL-Ltd: Plasma Products Agreement and other<br />

contractual arrangements 197<br />

BACKGROUND<br />

In 1994 CSL became a public company limited by shares and taken to be reg<strong>is</strong>tered<br />

under the Companies Act 1981 (Cwlth). At th<strong>is</strong> time, certa<strong>in</strong> leg<strong>is</strong>lative obligations were<br />

imposed upon CSL Limited, <strong>in</strong> l<strong>in</strong>e <strong>with</strong> the Commonwealth Serum Laboratories Act<br />

1961 (CSL Act), as described below:<br />

• Provide that CSL Limited <strong>is</strong> to rema<strong>in</strong> Australian-controlled.<br />

• CSL <strong>is</strong> also required to ma<strong>in</strong>ta<strong>in</strong> a reg<strong>is</strong>ter of foreign-held vot<strong>in</strong>g shares<br />

and must provide th<strong>is</strong> reg<strong>is</strong>ter, or a copy thereof, to the M<strong>in</strong><strong>is</strong>ter if<br />

requested to do so by the M<strong>in</strong><strong>is</strong>ter, <strong>in</strong> writ<strong>in</strong>g.<br />

• Require CSL, when manufactur<strong>in</strong>g plasma products from Australiandonated<br />

plasma, to produce those products <strong>in</strong> Australia.<br />

• Prohibit CSL from d<strong>is</strong>pos<strong>in</strong>g of its manufactur<strong>in</strong>g facility at<br />

Broadmeadows, which may not be sold or encumbered <strong>with</strong>out<br />

M<strong>in</strong><strong>is</strong>terial perm<strong>is</strong>sion.<br />

• Provide for court orders where the Commonwealth can show that CSL <strong>is</strong><br />

breach<strong>in</strong>g, or threaten<strong>in</strong>g to breach, a contractual obligation.<br />

An <strong>in</strong>d-depth analys<strong>is</strong> of fractionation arrangements had been carried out and<br />

completed <strong>in</strong> 2006 196 . In today’s form – Plasma Products Agreement mentioned above -<br />

relationship between CSL-Ltd and Australian health authorities can be summarized as a<br />

close partnership based on a monopoly for fractionation <strong>in</strong> exchange for strict and<br />

demand<strong>in</strong>g performance and safety standards 164 (see table below):

4.2.2.2 In France<br />

<strong>French</strong> Approach of self-sufficiency<br />

In France, there <strong>is</strong> no official and legal def<strong>in</strong>ition of “self-sufficiency” as such. However, a<br />

general approach of th<strong>is</strong> concept could be def<strong>in</strong>ed as the turnover of LFB (national<br />

fractionator enjoy<strong>in</strong>g the monopoly of EFS plasma fractionation) compared to the total<br />

turnover of fractionators operat<strong>in</strong>g <strong>in</strong> France. One must bear <strong>in</strong> m<strong>in</strong>d that the plasma<br />

product market <strong>is</strong> subject to competition. LFB must therefore compete <strong>with</strong> other firms<br />

(Baxter, Octapharma, etc…).<br />

Consider<strong>in</strong>g th<strong>is</strong> approach, it must be outl<strong>in</strong>ed that LFB meets 75% of the needs of the<br />

<strong>French</strong> market. However, it must be underl<strong>in</strong>ed that LFB corporate objective <strong>is</strong> to be <strong>in</strong><br />

the position to fulfil 100% of these needs <strong>in</strong> 2011 (specific <strong>in</strong>vestments have been<br />

planned accord<strong>in</strong>gly).<br />

Another important po<strong>in</strong>t <strong>is</strong> the very last update of the <strong>French</strong> regulation framework. In<br />

Summer 2009, the new <strong>French</strong> Law on Health Care organization (Loi Hôpital Patients<br />

Santé et Territoire – Loi HPST) officially stated that fulfill<strong>in</strong>g the <strong>French</strong> patients’ needs<br />

must be LFB’s priority (<strong>in</strong> return of its monopoly of EFS plasma fractionation).<br />

Supply of blood and plasma-derived products: the <strong>French</strong> monitor<strong>in</strong>g system<br />

Follow<strong>in</strong>g the shortage of Factor VIII <strong>in</strong> France <strong>in</strong> 2000-2001 (and consequential<br />

problems for haemophilia patients), the <strong>French</strong> Department of Health decided to set up<br />

a long-term monitor<strong>in</strong>g system -National Steer<strong>in</strong>g Committee- to address th<strong>is</strong> specific<br />

k<strong>in</strong>d of problems. <strong>The</strong> latter has been organized s<strong>in</strong>ce 2001 (by means of a Department<br />

of Health’s Circular dated 28 June 2001) under the leadership of the AFSSAPS Agence<br />

França<strong>is</strong>e de Sécurité Sanitaire des Produits de Santé– <strong>French</strong> Agency for the Safety of<br />

Health Products.<br />

Follow<strong>in</strong>g the meet<strong>in</strong>gs of these groups, and depend<strong>in</strong>g on the likelihood of shortage of<br />

plasma derivatives, national official recommendations – <strong>in</strong>clud<strong>in</strong>g priority orders - can be<br />

officially set out and publ<strong>is</strong>hed by the AFSSAPS and to rationalize the use of these<br />

products accord<strong>in</strong>gly (eg: Fibr<strong>in</strong>ogene-derived products <strong>in</strong> December 2008 and the<br />

follow<strong>in</strong>g months).


<strong>KCE</strong> Reports 120 Plasma 107<br />

As far as IVIG products are concerned, a specific steer<strong>in</strong>g group has been set up to<br />

organize rout<strong>in</strong>e monitor<strong>in</strong>g of IVIG products supply. All relevant private and public<br />

stakeholders are <strong>in</strong>volved: representatives of the Department of Health, several<br />

representatives of pharmac<strong>is</strong>ts (<strong>in</strong>cl. the <strong>French</strong> Pharmaceutical Association), Networks<br />

of heath care establ<strong>is</strong>hments, cl<strong>in</strong>ical experts, but also the lead<strong>in</strong>g fractionation firms on<br />

the <strong>French</strong> market.<br />

Supply and storage <strong>is</strong>sues are d<strong>is</strong>cussed every angle: data collection on consumption and<br />

supply, cl<strong>in</strong>ical dimension, <strong>in</strong>dustrial problems etc…<strong>The</strong> m<strong>in</strong>utes of these meet<strong>in</strong>gs are<br />

not public doma<strong>in</strong> and they rema<strong>in</strong> confidential. However, th<strong>is</strong> rout<strong>in</strong>e monitor<strong>in</strong>g<br />

system plays a key-role <strong>in</strong> shortage prevention and also covers the <strong>in</strong>terface between<br />

public dec<strong>is</strong>ion-makers and private fractionation <strong>in</strong>dustry on that matters.<br />

German approach of self-sufficiency<br />

As stated by Art 4.7 of the German Transfusion Act “Compensation <strong>is</strong> also an aspect of<br />

self-sufficiency. Should it not be allowed to pay a compensation, th<strong>is</strong> would cause a<br />

highly v<strong>is</strong>ible loss of donors. Th<strong>is</strong> would be counter-productive to the aim of selfsufficiency”.<br />

“Blood and Plasma donors may receive a compensation for the donation<br />

time and effort. However, th<strong>is</strong> compensation must not become a payment”.<br />

However, from a purely legal and conceptual po<strong>in</strong>t there <strong>is</strong> no one s<strong>in</strong>gle def<strong>in</strong>ition of<br />

“self-sufficiency” as such, but several ratios followed up on the national level by the Paul<br />

Ehrlich Institut thanks to a centralized data collection system.<br />

<strong>The</strong> key objective of the German Health Authorities <strong>is</strong> to have a clear overview of<br />

plasma quantities actually <strong>available</strong> for fractionation and also to analyze the German<br />

<strong>in</strong>dustry’s actual capacity to fractionate the German plasma.<br />

As often underl<strong>in</strong>ed by the Paul Ehrlich Institut’s experts, <strong>in</strong>creas<strong>in</strong>g plasma collection <strong>is</strong><br />

not an end <strong>in</strong> itself. A sensible approach requires a specific follow-op of plasma<br />

collection but also a specific monitor<strong>in</strong>g of the German actual fractionation capacity for<br />

the whole range of plasma products meet<strong>in</strong>g the German patients’ demand.<br />

Practical follow-up of self-sufficiency <strong>is</strong>sues<br />

Th<strong>is</strong> data collection system <strong>is</strong> a regulatory obligation, based on Article 21 and 22 of the<br />

German National Transfusion Act (“Transfusionsgesetz” <strong>in</strong> German).<br />

• Blood and plasma collectors (Red Cross, Private Centres, Municipal<br />

Centres, German Army) are subject to th<strong>is</strong> specific <strong>report</strong><strong>in</strong>g obligation,<br />

but also:<br />

• Fractionation <strong>in</strong>dustry : all firms act<strong>in</strong>g on the German market<br />

• On the demand side: panel doctors and hospitals and specialized health<br />

care establ<strong>is</strong>hments.<br />

Th<strong>is</strong> <strong>report</strong><strong>in</strong>g system refers to a specific data set, set out by the German regulation<br />

mentioned above. <strong>The</strong>refore, the German health authorities are <strong>in</strong> the position to<br />

organize a follow-up of a specific range of rout<strong>in</strong>e <strong>in</strong>dicators and to have a clear<br />

overview of Germany’s situation <strong>in</strong> terms of self-sufficiency.<br />

SUPPLY SIDE<br />

In practice all the concerned data are validated, sorted and entered onto the Paul<br />

Ehrlich Institut’s data bases. Consider<strong>in</strong>g our subject, one of the most accurate<br />

monitor<strong>in</strong>g tool <strong>is</strong> the “Balance Sheet” that records the follow<strong>in</strong>g flows (2006 Data):<br />

Thanks to th<strong>is</strong> follow-up of imports, the Institute can have a clear view of Germany’s<br />

situation for the whole range of plasma products, <strong>in</strong>clud<strong>in</strong>g those that are not<br />

manufactured <strong>in</strong> Germany.<br />

DEMAND SIDE<br />

A specific follow-up <strong>is</strong> also rout<strong>in</strong>ely carried out by the Paul Ehrlich Institut.<br />

- One of the self sufficiency key <strong>in</strong>dicators <strong>is</strong> the follow<strong>in</strong>g: “Quantities manufactured <strong>in</strong><br />

Germany relat<strong>in</strong>g to consumption <strong>in</strong> Germany”. Based on th<strong>is</strong> approach, the self-sufficiency<br />

ratios are:<br />

• Factor VIII from plasma : above 100%<br />

• Factor IX from plasma: 66%<br />

• IG (normal): 99%<br />

• IG (specific / Anti D): 94%<br />

• IG (other specific IGs): Above 100%<br />

Among all plasma products, some are not manufactured <strong>in</strong> Germany, but imports are<br />

subject to a prec<strong>is</strong>e follow-up. Consumption of each plasma product <strong>is</strong> also subject to a<br />

prec<strong>is</strong>e follow-up. However, <strong>in</strong> spite of th<strong>is</strong> follow-up mechan<strong>is</strong>m, the Paul Ehrlich<br />

Institute had to admit that there <strong>is</strong> some uncerta<strong>in</strong>ty about reliability of data on the<br />

latter subject.<br />

Recent strengthen<strong>in</strong>g of supply capacity <strong>in</strong> Germany (2000-2008)<br />

A DYNAMIC COLLECTION POLICY<br />

As a whole, the situation of Germany has evolved quite positively over the last ten<br />

years. Plasma actually collected <strong>in</strong> Germany has ra<strong>is</strong>ed from 1.5 million litters <strong>in</strong> 2000 to<br />

2.5 million litters <strong>in</strong> 2008.<br />

A SURGE IN PLASMA FRACTIONATION CAPACITY<br />

<strong>The</strong> amount of plasma actually fractionated <strong>in</strong> Germany has ra<strong>is</strong>ed accord<strong>in</strong>gly: 750 000<br />

litters <strong>in</strong> 2004, 1.2 Million litres <strong>in</strong> 2006 (see above), and 2 Million litres <strong>in</strong> 2008.<br />

4.2.2.4 In Canada<br />

Canadian h<strong>is</strong>torical background<br />

H<strong>is</strong>torically, gratuity of donation of blood and plasma has been considered as the<br />

underp<strong>in</strong>n<strong>in</strong>g pr<strong>in</strong>ciple of the whole Canadian donation system. In the n<strong>in</strong>eties, a major<br />

public health scandal called the “ta<strong>in</strong>ted blood scandal” seriously underm<strong>in</strong>ed the public<br />

and the donors’ trust <strong>in</strong> the donation <strong>in</strong>stitutions, especially the Canadian Red Cross.<br />

In compliance <strong>with</strong> the conclusions of the Krever Comm<strong>is</strong>sion of Inquiry of 1997 (see<br />

below), the Canadian Red Cross eventually transferred its blood and plasma services to<br />

the newly founded “Canadian Blood Services- CBS” (and Héma-Québec for th<strong>is</strong> latter<br />

prov<strong>in</strong>ce).<br />

Canadian Reflection on the ethical framework<br />

As mentioned above, the Krever Comm<strong>is</strong>sion of Inquiry conducted an <strong>in</strong>-depth analys<strong>is</strong><br />

of the whole donation system and <strong>is</strong>sued key statements (1997) on the pr<strong>in</strong>ciples that<br />

must underp<strong>in</strong> the future Canadian donation system (the follow<strong>in</strong>g po<strong>in</strong>ts are official<br />

statements):<br />

• “Donors of blood and plasma should not be paid, except <strong>in</strong> rare<br />

circumstances”<br />

• “Significant efforts must be made to ensure that blood products used <strong>in</strong><br />

Canada are made from unpaid donors”<br />

• “Plasma must be collected <strong>in</strong> sufficient quantities <strong>in</strong> Canada to meet<br />

domestic needs for blood products”<br />

• “Safety should be paramount”


<strong>KCE</strong> Reports 120 Plasma 109<br />

Follow<strong>in</strong>g these pr<strong>in</strong>ciples, gratuity of donation rema<strong>in</strong>ed untouched but security and<br />

quantitative aspects of plasma supply were also underl<strong>in</strong>ed. However, further pr<strong>in</strong>ciples<br />

also had to be taken <strong>in</strong>to account as set out by the Found<strong>in</strong>g Memorandum of<br />

Understand<strong>in</strong>g (1997):<br />

• Ensur<strong>in</strong>g access to a safe, secure and affordable supply of blood, blood<br />

products and alternatives, and supports their appropriate use.<br />

• Address<strong>in</strong>g <strong>in</strong>ventory imbalances (shortages / surpluses) to m<strong>in</strong>imize<br />

waste and ensure adequate supply<br />

• Consider<strong>in</strong>g dec<strong>is</strong>ion mak<strong>in</strong>g <strong>in</strong> a health r<strong>is</strong>k management framework<br />

which places on an equal foot<strong>in</strong>g the three critical elements of cost,<br />

benefit and r<strong>is</strong>k.<br />

<strong>The</strong>refore the newly founded donation system – ie the Canadian Blood Services to<br />

which the Red Cross donation activities were transferred – had to pursue several goals<br />

<strong>in</strong> the same time:<br />

• Ensur<strong>in</strong>g blood safety, which <strong>is</strong> of paramount importance consider<strong>in</strong>g the<br />

Canadian h<strong>is</strong>torical background. More generally it <strong>is</strong> an objective as such<br />

for any country.<br />

• Improv<strong>in</strong>g level of self-sufficiency <strong>is</strong> also an objective as such, from a public<br />

health and from a political po<strong>in</strong>t of view.<br />

• Increas<strong>in</strong>g volume of domestic donation for blood and plasma, which <strong>is</strong><br />

strongly connected <strong>with</strong> the previous po<strong>in</strong>t.<br />

• Ma<strong>in</strong>ta<strong>in</strong><strong>in</strong>g gratuity of donation, as a key ethical option.<br />

• Reduc<strong>in</strong>g r<strong>is</strong>k of supply d<strong>is</strong>ruption (especially <strong>in</strong> the field of IVIG) to avoid<br />

any danger for patients’ safety.<br />

Today’s situation of Canada <strong>in</strong> terms of IVIG self-sufficiency:<br />

In 2008-2009, Canada will be about:<br />

• 28% sufficient <strong>in</strong> IVIG (made from Canadian Plasma)<br />

• 72% of the IVIG d<strong>is</strong>tributed to Canadian hospitals comes from plasma<br />

collected commercially <strong>in</strong> the US<br />

<strong>The</strong>refore, Canada has to face two thorny problems simultaneously: security (as<br />

described above) but also a poor level of self-sufficiency, and thus possible d<strong>is</strong>ruption <strong>in</strong><br />

plasma (especially IVIG) supply. Once aga<strong>in</strong> th<strong>is</strong> situation <strong>is</strong> quite close to the Belgian<br />

one.<br />

Th<strong>is</strong> situation ra<strong>is</strong>ed several questions: the adequate of national self-sufficiency , the<br />

ways and means to reach th<strong>is</strong> level of self-sufficiency.<br />

Canadian strategy<br />

At the end of the reflection process, the official target of 100% Self-sufficiency through<br />

domestic collection and supply was eventually abandoned for Canadian Blood Services<br />

for the follow<strong>in</strong>g reasons:<br />

• It would require huge <strong>in</strong>vestments (18 new plasma centres <strong>with</strong><strong>in</strong> the next<br />

7 years)<br />

• It would not be cost efficient as Canadian production costs rema<strong>in</strong> much<br />

higher than the US ones.<br />

• It <strong>is</strong> not scientifically justified <strong>in</strong> terms of blood safety<br />

For all the reasons mentioned above, the official self-sufficiency target has been rev<strong>is</strong>ed<br />

downwards to 40%. A wide range of options had been orig<strong>in</strong>ally considered to close<br />

th<strong>is</strong> gap (28% to 40%): ra<strong>is</strong><strong>in</strong>g the level of domestic collection, improv<strong>in</strong>g processes,<br />

etc… Today’s Canadian strategy can thus be described as a “sufficiency aimed at<br />

optimally reduc<strong>in</strong>g r<strong>is</strong>k of IVIG supply d<strong>is</strong>ruption”. In practice it can be described as a<br />

“policy-mix”. In practice, several measures were implemented <strong>in</strong> the same time:<br />

• Improvement of collection methodology


110 Plasma <strong>KCE</strong> Reports 120<br />

Key po<strong>in</strong>ts<br />

• Re<strong>in</strong>troduction of source plasma collection at some sites, when required<br />

• Increased volume per collection<br />

• Usage of platelet additive solutions<br />

• Improvement of fractionation capacities: seek<strong>in</strong>g to have two<br />

fractionators licensed for Canadian plasma<br />

• <strong>The</strong>re <strong>is</strong> no universal def<strong>in</strong>ition of “self-sufficiency” but all selected countries<br />

have conducted an <strong>in</strong>-depth reflection on th<strong>is</strong> concept, <strong>in</strong> connection <strong>with</strong><br />

other subjects.<br />

• All selected countries have set up a monitor<strong>in</strong>g system of self-sufficiency<br />

ratios, or at least a centralized data collection on the subject.<br />

• Clear connection between self-sufficiency and remuneration <strong>is</strong>sues must be<br />

born <strong>in</strong> m<strong>in</strong>d.<br />

• Australian policy <strong>is</strong> probably the most comprehensive policy as it has<br />

establ<strong>is</strong>hed a close connection between th<strong>is</strong> dimension and all related <strong>is</strong>sues<br />

<strong>with</strong><strong>in</strong> the framework of the National Blood Authority, which covers all<br />

aspects of blood and plasma supply.<br />

4.3 HOW TO STAY OR BECOME SELF SUFFICIENT<br />

<strong>The</strong>re <strong>is</strong> no answer to the question of self sufficiency <strong>in</strong> terms of figures <strong>in</strong> th<strong>is</strong> <strong>report</strong>.<br />

Th<strong>is</strong> <strong>is</strong> a political choice to be made <strong>in</strong> the light of the r<strong>is</strong>k-aversion of Belgian dec<strong>is</strong>ionmakers.<br />

<strong>The</strong> fundamental question <strong>is</strong> to determ<strong>in</strong>e the desired level of <strong>in</strong>dependence.<br />

Supply security considerations must govern th<strong>is</strong> choice. For th<strong>is</strong> we need to determ<strong>in</strong>e<br />

whether the trend <strong>in</strong> demand <strong>in</strong> countries deemed to have a high level of consumption<br />

could lead to a shortage of derivative products. Such a r<strong>is</strong>k could also result if the<br />

collection <strong>in</strong> these countries no longer covered their own requirements for derivatives.<br />

Price levels and volatility are another r<strong>is</strong>k factor to be considered. Be<strong>in</strong>g more<br />

dependent on foreign supplies could mean suffer<strong>in</strong>g substantial price variations, which<br />

are the first adjustment variable affect<strong>in</strong>g variations <strong>in</strong> supply and demand. Beyond a<br />

certa<strong>in</strong> level of shortage, there are fears that simple purchas<strong>in</strong>g power may no longer be<br />

enough.<br />

To m<strong>in</strong>im<strong>is</strong>e the cost of production for Belgian plasma derivatives for a given level of<br />

coverage, we could strive for:<br />

• A reduction <strong>in</strong> the demand for these products<br />

• An <strong>in</strong>creas<strong>in</strong>g of the capacities of collect<strong>in</strong>g plasma<br />

• Transparency and better control of the supply of derivatives<br />

4.3.1 Strategies to decrease IG use: lessons learned<br />

4.3.1.1 Experience from other countries<br />

Several countries, confronted to <strong>in</strong>creased IG consumption, shortage or r<strong>is</strong>k of<br />

shortage, and grow<strong>in</strong>g cost, have publ<strong>is</strong>hed the measures that they planned or have<br />

undertaken to improve the supply and demand balance.(Hume, Anderson, TMR 2007;<br />

Constant<strong>in</strong>e 2007, UK DOH National Immunoglobul<strong>in</strong> Database Update j , Australia k ).<br />

However, very few studies have evaluated the impact of these measures.<br />

Table 45 summarized the overall strategies used <strong>in</strong> different countries. We focus here<br />

on the reduction of IG use. <strong>The</strong> ma<strong>in</strong> measures taken or proposed <strong>in</strong>clude:<br />

Classify<strong>in</strong>g <strong>in</strong>dications <strong>in</strong> priority groups for IG treatment<br />

A l<strong>is</strong>t of <strong>in</strong>dications for which IG can be used has been def<strong>in</strong>ed <strong>in</strong> most countries. In<br />

addition, a few countries such as France, the UK and Australia, that experienced<br />

shortage (or its r<strong>is</strong>k), have decided on prioritization of IG use and classified <strong>in</strong>dications<br />

(labeled or not) <strong>in</strong>to groups or higher and lower priority. However, th<strong>is</strong> classification<br />

has been applied <strong>in</strong> many different ways:<br />

• In Australia, very clear categories for priority sett<strong>in</strong>g have been<br />

establ<strong>is</strong>hed: 1. Conditions for which IG has an establ<strong>is</strong>hed therapeutic<br />

role; 2. conditions for which IVIg has an emerg<strong>in</strong>g therapeutic role; 3.<br />

conditions for which IVIg are used <strong>in</strong> exceptional circumstances; 4.<br />

conditions for which IVIg use <strong>is</strong> not <strong>in</strong>dicated.<br />

• In the UK, three well def<strong>in</strong>ed categories have been establ<strong>is</strong>hed, coded by<br />

colour (red, blue and grey), to facilitate the cl<strong>in</strong>ician understand<strong>in</strong>g of the<br />

level of priority.<br />

• In France, the drug agency (AFSSAPS) def<strong>in</strong>ed 7 groups, us<strong>in</strong>g different<br />

levels of priority, d<strong>is</strong>t<strong>in</strong>gu<strong>is</strong>h<strong>in</strong>g labeled and non labeled <strong>in</strong>dications, <strong>with</strong><br />

no clear rationale; the priority of each group of <strong>in</strong>dications above the<br />

others <strong>is</strong> not always clear. l<br />

A difficulty <strong>with</strong> th<strong>is</strong> system <strong>is</strong> that the rationale beh<strong>in</strong>d the choice of classification <strong>is</strong> not<br />

always stated or made clear, the categories need to be regulary updated, and the<br />

application of th<strong>is</strong> priorization <strong>is</strong> not always described: <strong>in</strong> the absence of shortage,<br />

should a patient from a last priority group receive IG or not?<br />

Establ<strong>is</strong>h<strong>in</strong>g guidel<strong>in</strong>es and criteria for use<br />

<strong>The</strong> Canada, Australia and the UK have <strong>in</strong>vested important resources and time to<br />

produce guidel<strong>in</strong>es, based on evidence and consensus sessions among experts:<br />

• <strong>The</strong> Canadian Blood Services and the National Adv<strong>is</strong>ory Committee on<br />

Blood and Blood Products began <strong>in</strong> 2004 to develop detailed and evidence<br />

based guidel<strong>in</strong>es for the use of IVIG <strong>in</strong> hematological and neurological<br />

conditions. <strong>The</strong> results of th<strong>is</strong> work are publ<strong>is</strong>hed <strong>in</strong> a supplement of the<br />

journal Transfusion Medic<strong>in</strong>e Reviews <strong>in</strong> 2007. 18-21<br />

• In Australia, the “Criteria for the Cl<strong>in</strong>ical Use of Intravenous<br />

Immunoglobul<strong>in</strong>” was developed <strong>in</strong> 2004-2007, based on evidence<br />

identified through systematic reviews of the literature and the op<strong>in</strong>ions of<br />

cl<strong>in</strong>ical experts. <strong>The</strong> cl<strong>in</strong>ical criteria are conta<strong>in</strong>ed <strong>with</strong><strong>in</strong> condition proforma<br />

and have been set out to cover four major <strong>is</strong>sues: l<strong>is</strong>t of <strong>in</strong>dications<br />

for IG use; qualify<strong>in</strong>g criteria, exclusion criteria and review criteria. 22<br />

• In the UK, as part of the “Demand Management Programme”, National<br />

Cl<strong>in</strong>ical Guidel<strong>in</strong>es for the appropriate use of IVIG have been produced<br />

based on <strong>available</strong> evidence and expert op<strong>in</strong>ion <strong>in</strong> the period 2006-2008.<br />

After literature review and expert review, <strong>in</strong>terested bodies reg<strong>is</strong>tered as<br />

“Stakeholders” provided comments on the document. Regular updates<br />

are ensured, at least yearly.<br />

• In France, the CEDIT has <strong>is</strong>sued recommendations that are widely used.<br />

National guidel<strong>in</strong>es are also expected at national level, based on the<br />

CEDIT work. l<br />

• In Australia, the concept of ‘criteria for use’ constitutes a more directive<br />

framework for dec<strong>is</strong>ions about the use of a particular treatment, as<br />

opposed to the concept of “guidel<strong>in</strong>es” that usually refer to the<br />

management of conditions rather than to the use of specific therapeutic<br />

products such as IVIG. 22 <strong>The</strong> latter term has been selected to describe the<br />

circumstances, based on evidence and cl<strong>in</strong>ical experience, under which the<br />

cl<strong>in</strong>ical use of IVIG <strong>is</strong> considered appropriate <strong>in</strong> Australia.<br />

It should be noted that <strong>in</strong> each country, the production of guidel<strong>in</strong>es has cost a<br />

considerable amount of time (around 3 years), <strong>in</strong> literature review and negotiations <strong>with</strong><br />

experts and stakeholders. Guidel<strong>in</strong>es also need to be regularly updated.<br />

Only one study assessed the impact of guidel<strong>in</strong>es on IG use. In the Atlantic region of<br />

Canada, a study compared IVIG use between a basel<strong>in</strong>e phase (2003-2004) before<br />

guidel<strong>in</strong>e use, and after implementation of “optimization tools” (2005). In the second<br />

period, they found a 7% decrease <strong>in</strong> IG use, contrast<strong>in</strong>g <strong>with</strong> the previous annual r<strong>is</strong>es<br />

(7% <strong>in</strong> 2002-03 to 2003-04 and 10% from 2003-04 to 2004-05). 146<br />

Limit<strong>in</strong>g prescription of IG to specific groups<br />

In the UK under the “Comm<strong>is</strong>sion<strong>in</strong>g Policy”, all immunoglobul<strong>in</strong> must be prescribed by<br />

a consultant <strong>with</strong> special<strong>is</strong>t knowledge of its use; no GP may prescribe. Prescribers must<br />

monitor future communications on any r<strong>is</strong>ks to supply and understand the mechan<strong>is</strong>m<br />

for handl<strong>in</strong>g any shortages.


<strong>KCE</strong> Reports 120 Plasma 113<br />

Improv<strong>in</strong>g awareness of cl<strong>in</strong>icians and patients<br />

Two countries mention the <strong>in</strong>formation to cl<strong>in</strong>icians <strong>in</strong> their plan: France planned to<br />

implement <strong>in</strong>formation to pharmac<strong>is</strong>ts and prescribe. m In the UK, the demand<br />

management programme states that patients should be fully <strong>in</strong>formed of arrangements<br />

for their treatment and the implications of any supply shortages.<br />

Improv<strong>in</strong>g evaluation of use and monitor<strong>in</strong>g<br />

Several countries have <strong>in</strong>itiated a reg<strong>is</strong>try for patients under IG treatment or a national<br />

database. However, no further <strong>in</strong>formation <strong>is</strong> <strong>available</strong> on the application of these<br />

systems and its impact.<br />

• In the UK, the “Comm<strong>is</strong>sion<strong>in</strong>g Policy” stated that all patients should be<br />

logged <strong>with</strong> the national immunoglobul<strong>in</strong> database and their data provided.<br />

All patients receiv<strong>in</strong>g long-term immunoglobul<strong>in</strong> should be reviewed<br />

annually to assess d<strong>is</strong>ease activity and determ<strong>in</strong>e the best therapeutic<br />

option.<br />

• In Australia, <strong>The</strong> national Blood Agency has also <strong>in</strong>cluded <strong>in</strong> its plans the<br />

development of a system to collect data that will provide <strong>in</strong>formation<br />

about the effectiveness of IVIG therapy. 22 Th<strong>is</strong> <strong>in</strong>formation was planned to<br />

be assessed by experts and used to <strong>in</strong>form future reviews of th<strong>is</strong> “criteria<br />

for use”. However, we have no <strong>in</strong>formation on whether th<strong>is</strong> strategy has<br />

been effectively implemented.<br />

• In some Canadian regions, such as the Atlantic Prov<strong>in</strong>ces, a work<strong>in</strong>g group<br />

was created to monitor IVIG use and a reg<strong>is</strong>try of IVIG was created.<br />

Assessment of <strong>in</strong>dication appropriateness <strong>is</strong> determ<strong>in</strong>ed based on<br />

guidel<strong>in</strong>es, and feedback <strong>report</strong>s are d<strong>is</strong>tributed to stakeholders.<br />

• France launched a data collection on IVIG consumption per <strong>in</strong>dication, to<br />

evaluate the appropriateness of IVIG use <strong>in</strong> cl<strong>in</strong>ical practice.<br />

Other lessons learned<br />

In the US, a shortage <strong>in</strong> IVIG occurred <strong>in</strong> 1997. 198 <strong>The</strong> authorities <strong>in</strong>formed the medical<br />

community but did not respond to the shortage <strong>in</strong> a timely of effective manner. Instead,<br />

it took a passive role, leav<strong>in</strong>g IVIG manufacturers and d<strong>is</strong>tributors, health care<br />

<strong>in</strong>stitutions, and cl<strong>in</strong>icians to fend for themselves. Regulatory steps and<br />

recommendations were made but after prolonged debate. No updated national<br />

recommendation on appropriate use of IVIG has been <strong>is</strong>sued. Institutions have<br />

developed their own guidel<strong>in</strong>es to restrict the use of IVIG for off-label conditions.<br />

Guidel<strong>in</strong>es varied substantially across <strong>in</strong>stitutions. Consequently IVIG was d<strong>is</strong>tributed at<br />

often extremely elevated prices and not accord<strong>in</strong>g to the criteria of need and urgency.<br />

<strong>The</strong> shortage likely had an uneven impact on patients, based on the relative market<br />

strength of the health care <strong>in</strong>stitutions <strong>in</strong> which they received care and the <strong>in</strong>dividual<br />

patient's ability to absorb the <strong>in</strong>creas<strong>in</strong>g out-of-pocket costs of scarce IVIG.<br />

Overall impact of strategies to reduce IG use<br />

Several countries are conduct<strong>in</strong>g audits <strong>in</strong> hospitals (eg. the UK and the US) but few<br />

countries have evaluated the overall impact of their set of strategies on IG<br />

consumption.<br />

In France, the last <strong>available</strong> consumption data from the “Hôpitaux de Par<strong>is</strong>”, follow<strong>in</strong>g<br />

the CEDIT guidel<strong>in</strong>es and prioritization, date from 2005 and show an <strong>in</strong>crease <strong>in</strong> IVIG<br />

use (+18%). Th<strong>is</strong> <strong>in</strong>crease <strong>is</strong> however lower than the <strong>in</strong>crease observed at national level<br />

(+24%). n<br />

4.3.1.2 Experiences from Belgium<br />

In Belgium, the Health Council (CSS/HGR) has developed guidel<strong>in</strong>es for the use of red<br />

blood cells <strong>in</strong> January 2007, p and for the use of frozen plasma <strong>in</strong> 2007. q After the<br />

guidel<strong>in</strong>es were <strong>is</strong>sued, the consumption of both products decreased. Guidel<strong>in</strong>es on the<br />

use of immunoglobul<strong>in</strong>s are currently be<strong>in</strong>g developed at the Health Council and should<br />

be <strong>available</strong> <strong>in</strong> the near future.<br />

In the late n<strong>in</strong>eties, the BIOMED project used the technique of “benchmark<strong>in</strong>g”<br />

(restitution of data document<strong>in</strong>g <strong>in</strong>dividual performance and compar<strong>is</strong>on of these data<br />

<strong>with</strong> the group average or <strong>with</strong> external references) to impact on the red cell<br />

transfusion. After the thorough restitution of data and <strong>with</strong>out the <strong>in</strong>troduction of new<br />

regulations or guidel<strong>in</strong>es, time was given to the participants to improve their practices,<br />

by us<strong>in</strong>g the strategies they deemed most appropriate for their local situation. Data<br />

collected 2.5 years later showed that the use of blood and blood products decreased<br />

markedly: a reduction of the order of 20%-25% was achieved over a 2 to 3 year period.<br />

<strong>The</strong> reduction of red cell transfusion has been obta<strong>in</strong>ed <strong>with</strong>out any change <strong>in</strong><br />

hematocrits at any time dur<strong>in</strong>g hospital stay for any surgical procedure. 199<br />

4.3.2 Strategies to decrease IG use: what could be applied <strong>in</strong> Belgium<br />

Overall, the follow<strong>in</strong>g measures could be considered for implementation <strong>in</strong> Belgium:<br />

• Def<strong>in</strong><strong>in</strong>g a l<strong>is</strong>t of <strong>in</strong>dications for IG use, based on <strong>available</strong> evidence and<br />

expert panels. A l<strong>is</strong>t of reimbursed <strong>in</strong>dications <strong>is</strong> already def<strong>in</strong>ed and<br />

regularly updated <strong>in</strong> Belgium, but several <strong>in</strong>dications which have shown a<br />

benefit based on evidence are not <strong>in</strong>cluded (see Chapter II). It <strong>is</strong> unclear<br />

how these d<strong>is</strong>eases are currently treated <strong>in</strong> Belgium, and it <strong>is</strong> possible that<br />

significant amounts of IG are given under compassionate use.<br />

• Classify<strong>in</strong>g these <strong>in</strong>dications <strong>in</strong> priority groups for IG treatment (high<br />

priority, low priority). However, establ<strong>is</strong>h<strong>in</strong>g these priorities must be<br />

based on evidence and requires consensus and regular update. <strong>The</strong><br />

application of these classifications <strong>in</strong> practice (how to treat these patients)<br />

<strong>is</strong> not always clear. In some countries, patients from the low priority<br />

group may be treated <strong>with</strong> IG unless there <strong>is</strong> a IG shortage.<br />

• Establ<strong>is</strong>h<strong>in</strong>g guidel<strong>in</strong>es and criteria for use. In countries where guidel<strong>in</strong>es<br />

have been developed as a response to IG shortage, th<strong>is</strong> has requested<br />

important resources <strong>in</strong> terms of persons, time required (2-3 years) and<br />

expert panels and consensus. In Belgium, the Health Council <strong>is</strong> <strong>in</strong> the<br />

process of develop<strong>in</strong>g guidel<strong>in</strong>es that should be <strong>is</strong>sued at end of 2009. <strong>The</strong><br />

Belgian experience <strong>with</strong> similar guidel<strong>in</strong>es (for the use of red cell<br />

transfusion and fresh frozen plasma) has shown positive results <strong>in</strong> terms<br />

of practice and reduction of consumption. It should be noted that<br />

guidel<strong>in</strong>es also need to be regularly updated.<br />

• Limit<strong>in</strong>g prescription of IG to specific groups of prescribers. In Belgium, a<br />

high IG amount <strong>is</strong> prescribed by ass<strong>is</strong>tants <strong>in</strong> specialization (<strong>in</strong> academic<br />

hospitals) and a IG amounts are sometimes prescribed by peripheral<br />

hospitals for specialties that should <strong>in</strong> pr<strong>in</strong>ciple not use significant<br />

amounts. An option would be to limit the <strong>in</strong>itiation and superv<strong>is</strong>ion of IG<br />

treatment to a number of “IG reference centres”, follow<strong>in</strong>g the same<br />

model than the centres for haemophilia centres or for bone marrow<br />

transplants, through convention <strong>with</strong> the INAMI/RIZIV.<br />

• Improv<strong>in</strong>g awareness of cl<strong>in</strong>icians and patients. In Belgium, cl<strong>in</strong>icians have<br />

access to evidence based literature, but receive no direct <strong>in</strong>formation on<br />

the cost of IG and the r<strong>is</strong>k of shortage; good <strong>in</strong>formation on these aspects<br />

could help decrease the prescription of IG for the <strong>in</strong>dications <strong>in</strong> which no<br />

benefit has been proven.<br />

• Improv<strong>in</strong>g evaluation of use and monitor<strong>in</strong>g. A reg<strong>is</strong>try for patients under<br />

long term IG treatment or a national data bas<strong>is</strong> could be a tool to allow a<br />

better monitor<strong>in</strong>g of IG use and assess <strong>in</strong>dication appropriateness based<br />

on guidel<strong>in</strong>es. Th<strong>is</strong> data collection could also be used for a<br />

“benchmark<strong>in</strong>g” method, which has been successfully used for red cell<br />

transfusion <strong>in</strong> Belgium <strong>in</strong> the late n<strong>in</strong>eties (see above).<br />

4.3.3 Increas<strong>in</strong>g the capacities of collect<strong>in</strong>g plasma<br />

A major part of the cost of collect<strong>in</strong>g plasma doubtless stems from the difficulty <strong>in</strong><br />

f<strong>in</strong>d<strong>in</strong>g donors and the efforts made to seek out and persuade them. It seems selfevident<br />

that a greater number of donors would allow economies of scale <strong>in</strong> the<br />

collection of plasma and might result <strong>in</strong> collect<strong>in</strong>g more than <strong>is</strong> required to cover the<br />

needs of Belgium as def<strong>in</strong>ed by the concept of self-sufficiency <strong>in</strong> the Royal Decree of 18<br />

June 1998. <strong>The</strong> Red Cross could then export at a market price higher than the price it<br />

sells to the CAF-DCF. <strong>The</strong> subsidies could then be reduced accord<strong>in</strong>gly.


116 Plasma <strong>KCE</strong> Reports 120<br />

To attract a larger number of donors it would not be allowed to resort to pay<strong>in</strong>g for<br />

the blood or plasma collected. <strong>The</strong> pr<strong>in</strong>ciple of voluntary donation free of charge<br />

constitutes the essential ethical framework for all European countries. But the likes of<br />

advert<strong>is</strong><strong>in</strong>g campaigns, benefits <strong>in</strong> k<strong>in</strong>d and tax breaks could be considered and set up at<br />

a cost probably lower than that of the subsidies given to the Red Cross to arrive at the<br />

same result.<br />

In most European countries (see part 1 of th<strong>is</strong> <strong>report</strong>), <strong>in</strong> particular France and<br />

Germany, it clearly emerges that a major effort has been made <strong>in</strong> recent years aimed at<br />

the priority age groups, namely 18-25 years, usually <strong>in</strong>volv<strong>in</strong>g a close partnership <strong>with</strong><br />

the schools and universities concerned. More generally, communication campaigns us<strong>in</strong>g<br />

a wide variety of media have been implemented, pay<strong>in</strong>g special attention to manag<strong>in</strong>g<br />

the donors over time <strong>in</strong> order to improve their loyalty.<br />

Germany has given special thought to the geographical location of plasma collection<br />

centres <strong>in</strong> relation to the profile of potential donors, <strong>in</strong> particular <strong>in</strong> terms of age.<br />

It <strong>is</strong> nevertheless necessary to reflect on the different treatment currently given to<br />

private sector and public sector employees. <strong>The</strong> quest for equal treatment of all<br />

donors could lead the authority to reduce the benefits, <strong>in</strong> terms of days of leave,<br />

granted to members of the public services and make donat<strong>in</strong>g blood and plasma totally<br />

charitable. Th<strong>is</strong> would open up the possibility of reconvert<strong>in</strong>g the result<strong>in</strong>g sav<strong>in</strong>gs <strong>in</strong>to<br />

campaigns promot<strong>in</strong>g blood and plasma donation.<br />

F<strong>in</strong>ally, a wide-rag<strong>in</strong>g debate <strong>in</strong> terms of demographic prospects has taken place <strong>in</strong><br />

Germany <strong>in</strong> order to emphas<strong>is</strong>e the importance of th<strong>is</strong> dimension for the future<br />

sat<strong>is</strong>faction of the needs of the population. Th<strong>is</strong> debate will make possible better<br />

forecast<strong>in</strong>g of the donor population.<br />

4.3.4 Transparency and better control of the supply of derivatives<br />

As we have already seen, it seems that the quantities of derivatives sold <strong>in</strong> Belgium by<br />

the CAF-DCF are below what the firm should be able to produce if she were us<strong>in</strong>g all<br />

the quantity of plasma sold to it by the Red Cross. <strong>The</strong>re are various possible<br />

explanations for th<strong>is</strong> situation, but the <strong>in</strong>formation <strong>available</strong> does not enable us to<br />

identify the correct ones, largely because of the complexity of the market and of the<br />

fractionation circuit implemented via agreements <strong>with</strong> foreign firms, the terms of which<br />

are not known to us.<br />

Given the <strong>in</strong>direct subsidy granted to the CAF-DCF via the below-market price at<br />

which plasma <strong>is</strong> sold to it, it would make sense to have public control over the terms<br />

and costs of its agreements <strong>with</strong> foreign partners.<br />

Relations between the organ<strong>is</strong>ations responsible for collection and fractionation are a<br />

delicate and complex subject <strong>in</strong> all western countries.<br />

France and Germany first sought to ensure standard<strong>is</strong>ation of the technical collection<br />

process (<strong>in</strong> particular the volume of <strong>in</strong>dividual donations) <strong>in</strong> order to improve the<br />

volumes effectively delivered to the fractionation firms, <strong>with</strong> the same number of<br />

donors.<br />

Of all the countries studied, it <strong>is</strong> <strong>with</strong>out doubt <strong>in</strong> Australia where the debate on<br />

contractual relations between the fractionator and the other actors <strong>in</strong>volved has gone<br />

furthest. <strong>The</strong> contract b<strong>in</strong>d<strong>in</strong>g the National Blood Authority and the fractionator (CSL-<br />

Ltd) covers all aspects of the relationship between the two partners, <strong>in</strong>clud<strong>in</strong>g the<br />

f<strong>in</strong>ancial, log<strong>is</strong>tical, technical (health security, r<strong>is</strong>k management) and legal dimensions<br />

(ownership clause, appeal jur<strong>is</strong>dictions, etc.). Th<strong>is</strong> contractual relationship also takes<br />

<strong>in</strong>to account that the National Blood Authority <strong>is</strong> responsible for all functions touch<strong>in</strong>g<br />

on the question of the supply and d<strong>is</strong>tribution of blood and plasma products <strong>with</strong><strong>in</strong> the<br />

country.


<strong>KCE</strong> Reports 120 Plasma 117<br />

4.4 CONCLUSIONS<br />

<strong>The</strong> <strong>is</strong>sue of the <strong>in</strong>dependence of supplies of plasma derivatives <strong>is</strong> fundamentally a<br />

political one, and the public authorities must def<strong>in</strong>e the degree of <strong>in</strong>dependence they<br />

w<strong>is</strong>h to achieve and, as a corollary, the degree of <strong>in</strong>security that they are will<strong>in</strong>g to<br />

accept. <strong>The</strong> substance of these choices would then determ<strong>in</strong>e the measures to be<br />

taken <strong>with</strong><strong>in</strong> the three fields of action identified <strong>in</strong> th<strong>is</strong> <strong>report</strong>: plasma collection, the<br />

production of plasma derivatives and the consumption of these derivatives. Each of<br />

these fields concerns different actors that require specific <strong>in</strong>struments <strong>in</strong> order to move<br />

towards the collection of more plasma, more profitable transformation of plasma <strong>in</strong>to<br />

derivatives, and consumption of derivatives more <strong>in</strong> step <strong>with</strong> recogn<strong>is</strong>ed medical<br />

conditions. Ma<strong>in</strong>ta<strong>in</strong><strong>in</strong>g or <strong>in</strong>creas<strong>in</strong>g our <strong>in</strong>dependence therefore requires the<br />

application of a comb<strong>in</strong>ation of measures <strong>in</strong> these three fields. However, <strong>in</strong>dependently<br />

of any quest for a specific degree of <strong>in</strong>dependence, it would appear that consumption<br />

that sat<strong>is</strong>fies the rules of good practice, collection at m<strong>in</strong>imum cost and sat<strong>is</strong>factory<br />

yields from the fractionation process are basic requirements. <strong>The</strong> scale of each possible<br />

measure must be l<strong>in</strong>ked to establ<strong>is</strong>hed facts, <strong>in</strong> which respect it <strong>is</strong> important to take <strong>in</strong>to<br />

account the limitations of any scientific study. In th<strong>is</strong> case they concern <strong>in</strong>ternational<br />

prices and certa<strong>in</strong> data relat<strong>in</strong>g to the consumption of derivative products. For each of<br />

these limitations, further studies would make the results more robust, not forgett<strong>in</strong>g<br />

the confidential nature of certa<strong>in</strong> data, which will always be subject to some uncerta<strong>in</strong>ty.<br />

Nevertheless, it <strong>is</strong> not necessary to wait for certa<strong>in</strong>ty regard<strong>in</strong>g every parameter before<br />

tak<strong>in</strong>g the necessary measures.

5 APPENDICES<br />

APPENDIX 1: ETHICAL DIMENSION OF<br />

DONATION: QUICK OVERVIEW<br />

REASONS FOR DONATING BLOOD AND PLASMA: EMPIRIC<br />

ANALYSIS<br />

A specific “motivation model” ie a motivation ethical framework has been identified and<br />

recently set out by God<strong>in</strong> <strong>in</strong> one of h<strong>is</strong> most recent articles [God<strong>in</strong> et al “Factors<br />

expla<strong>in</strong><strong>in</strong>g the <strong>in</strong>tention to give blood among the general population Vox Sangu<strong>in</strong><strong>is</strong><br />

(2005) 89, 140-149 et al. 2005] 200 . In th<strong>is</strong> Canadian study (Québec), all these factors<br />

where analyzed both <strong>in</strong> the “never donors” group (ie <strong>in</strong>dividuals who never donated)<br />

and <strong>in</strong> the “ever donors” group (<strong>in</strong>dividuals who donated, at least one).<br />

External variables (<strong>in</strong>dividual and collective alike) are apt to have an impact on 3 types of<br />

ethical factors:<br />

• Attitudes (cognitive attitudes, but also emotional attitudes)<br />

• Accepted norms: perceived behaviour control, moral norms as accepted<br />

<strong>in</strong> a specific country (at a specific time of h<strong>is</strong>tory), and past experience of<br />

donation.<br />

• Controls (self-<strong>in</strong>itiated controls or society-<strong>in</strong>itiated controls)<br />

<strong>The</strong> three ethical factors mentioned above determ<strong>in</strong>e the “<strong>in</strong>tention to donate”, which<br />

turns <strong>in</strong>to actual behaviour (ie actual donation) provided resources are <strong>available</strong> to<br />

perform it.<br />

In both groups - “Ever donors” and “Never donors” – morals norms and perceived<br />

controls appeared as the most important factors.<br />

PRINCIPLES UNDERPINNING BLOOD DONATION<br />

Utilitarian<strong>is</strong>m: do<strong>in</strong>g what <strong>is</strong> good / dec<strong>is</strong>ions are made ow<strong>in</strong>g to the consequences of a<br />

specific behaviour. From a purely practical po<strong>in</strong>t of view, cost/effectiveness (both on the<br />

<strong>in</strong>dividual and social level) reason<strong>in</strong>g <strong>is</strong> the key pr<strong>in</strong>ciple underp<strong>in</strong>n<strong>in</strong>g dec<strong>is</strong>ion-mak<strong>in</strong>g<br />

processes. <strong>The</strong>refore people should donate, regardless of their motives. Blood donation<br />

must be organized <strong>in</strong> such a way that maximizes rentability of donation (<strong>in</strong>centives,<br />

attractive and comfortable framework, etc…).<br />

Duty-Ethics: do<strong>in</strong>g what must be done and motivated by fair <strong>in</strong>tention. Donation <strong>is</strong><br />

send and considered from the po<strong>in</strong>t of view of realization of each <strong>in</strong>dividual’s freedom.<br />

However, each <strong>in</strong>dividual’s behaviour “duty-ethical” behaviour <strong>is</strong> supposed to be<br />

considered and acknowledged as a general rule.<br />

Contract-Ethics: donation can be seen as a part of the whole social contract. <strong>The</strong> latter<br />

can be seen as a cluster of common rules def<strong>in</strong>ed for the same common benefit<br />

(solidarity).<br />

Virtue-Ethics: who can be considered as an “virtuous <strong>in</strong>dividual”. <strong>The</strong> whole concept<br />

of “virtue” <strong>is</strong> applied to the whole <strong>in</strong>dividual and not to specific behaviour or punctual<br />

act. Donation <strong>is</strong> the expression of mutual dependence between people.<br />

In short, and from an “ethical values” po<strong>in</strong>t of view, people must donate blood because:<br />

• It <strong>is</strong> useful<br />

• It <strong>is</strong> a duty<br />

• It <strong>is</strong> the expression of solidarity<br />

• It <strong>is</strong> a proof of virtue


<strong>KCE</strong> Reports 120 Plasma 119<br />

FAVOURING AND HINDERING FACTORS<br />

Given the background mentioned above, favour<strong>in</strong>g and h<strong>in</strong>der<strong>in</strong>g factors have obviously<br />

been identified <strong>in</strong> the very specific field of blood and plasma donation.<br />

Favour<strong>in</strong>g factors:<br />

H<strong>in</strong>der<strong>in</strong>g factors<br />

• Altru<strong>is</strong>m<br />

• Role-identity<br />

• Social rules<br />

• Facilitat<strong>in</strong>g framework (log<strong>is</strong>tics <strong>is</strong>sues) as identified by God<strong>in</strong> et al 2005,<br />

especially short d<strong>is</strong>tance between the potential donor’s home and the<br />

blood donation centre<br />

• Positive effects of the donation for the donor<br />

Perceived negative effect of donation and fears among potential donors about donation<br />

(fear of needles, fear of fa<strong>in</strong>t<strong>in</strong>g experience, etc..)<br />

Log<strong>is</strong>tic problems: long d<strong>is</strong>tance between the donor’s home and the donation centre,<br />

but also lack of <strong>in</strong>timacy.<br />

“Free-rider” behaviour, applied to donation as expla<strong>in</strong>ed by David B. Johnson <strong>in</strong> the<br />

Brit<strong>is</strong>h Journal of Psychology 1982 201 , ie <strong>in</strong>dividual’s reluctance to donate because the<br />

<strong>in</strong>dividual contribution would have no effect no perceptible effect on the overall<br />

prov<strong>is</strong>ion of blood and that the <strong>in</strong>dividual himself cannot be excluded from enjoy<strong>in</strong>g the<br />

benefits of the system (if case of need).<br />

Ma<strong>in</strong> learn<strong>in</strong>gs: people’s reluctance to donate <strong>is</strong> ma<strong>in</strong>ly expla<strong>in</strong>ed by perceived<br />

psychological, physical or practical barriers and obstacles regard<strong>in</strong>g donation (even the<br />

latter have little to do <strong>with</strong> reality). <strong>The</strong>refore donation promotional strategies should<br />

be adapted accord<strong>in</strong>gly and focus on elim<strong>in</strong>ation of these barriers. Strategies should<br />

obviously be adapted to each population group (donors and non donors).<br />

Profile of donors’ population<br />

Consider<strong>in</strong>g Austrian compensation policy, the profile of whole blood donors and the<br />

one of plasma donors (as identified by the research team) rema<strong>in</strong>s quite different.<br />

Plasma donors are <strong>in</strong> average:<br />

• younger (18-35 important age group)<br />

• more educated (students)<br />

• less apt to live <strong>in</strong> stable couples (s<strong>in</strong>gle)<br />

• less <strong>in</strong>volved <strong>in</strong> professional life (students, jobless), than whole blood<br />

donors.


120 Plasma <strong>KCE</strong> Reports 120<br />

Remuneration of donation / Empiric f<strong>in</strong>d<strong>in</strong>gs for Austria<br />

One must bear <strong>in</strong> m<strong>in</strong>d that f<strong>in</strong>ancial compensation <strong>is</strong> an extremely ambivalent and<br />

controversial <strong>is</strong>sue, as it may be either a h<strong>in</strong>der<strong>in</strong>g or a factor, depend<strong>in</strong>g on the ex<strong>is</strong>t<strong>in</strong>g<br />

cultural and <strong>in</strong>stitutional framework of the country where donation <strong>is</strong> performed.<br />

As identified by the Austrian research team of the University of Vienna a change <strong>in</strong><br />

remuneration policy would have a major impact on donors’ behaviour, ie:<br />

• should remuneration for whole blood donation be <strong>in</strong>troduced, 84.3% of<br />

whole blood donors would stop donat<strong>in</strong>g whole blood<br />

• conversely, should remuneration for plasma donation be stopped 56.2% of<br />

plasma donors would stop donat<strong>in</strong>g plasma<br />

Likew<strong>is</strong>e, it was clearly mentioned that donor’s motives for donation rema<strong>in</strong> very<br />

different, especially towards the concept of altru<strong>is</strong>m vs remuneration: For whole blood<br />

donors, altru<strong>is</strong>m as such <strong>is</strong> an important motive for 88.2% for donation, whereas only<br />

50% of plasma donors feel concerned <strong>with</strong> th<strong>is</strong> k<strong>in</strong>d of motives. In the same time 52.1%<br />

of plasma donors clearly mention remuneration as one of the fix elements of their<br />

monthly <strong>in</strong>comes.<br />

which we have broadly categorized as observational studies and randomized trials. Study<br />

quality refers to the detailed study methods and execution. Cons<strong>is</strong>tency refers to the<br />

similarity of estimates of effect across studies. Directness refers to the extent to which<br />

the people, <strong>in</strong>terventions, and outcome measures are similar to those of <strong>in</strong>terest.<br />

Another type of <strong>in</strong>direct evidence ar<strong>is</strong>es when there are no direct compar<strong>is</strong>ons of<br />

APPENDIX 5: POTENTIAL CHANGES IN DEMAND<br />

VOLUME: FOCUS ON TWO EMERGING<br />

COUNTRIES<br />

FOCUS ON THE BRAZILIAN MARKET<br />

Brazil’s demand of plasma-derived products<br />

In the early n<strong>in</strong>eties, Brazilian plasma fractionation market was considered as a relatively<br />

m<strong>in</strong>or one. However, due to the <strong>in</strong>creas<strong>in</strong>g demand of the population and the evolution<br />

of prescription habits, Brazil’s demand for plasma products surged dramatically between<br />

1992 and 2007, and more prec<strong>is</strong>ely over the last three years.<br />

On th<strong>is</strong> market, and despite the surge of the population’s needs and demand, no<br />

domestic company has emerged yet and Brazilian companies are virtually absent: <strong>in</strong><br />

2007, sixteen foreign companies (profit and non profit) fractioned and sold almost 100%<br />

of plasma products, and four of them hold key positions (Baxter, Octapharma, CSL-<br />

Behr<strong>in</strong>g, BPL) as described below :<br />

As far as IVIG <strong>is</strong> concerned, Octapharma <strong>is</strong> clearly the market leader (market share of<br />

42%).<br />

Structure of th<strong>is</strong> market <strong>is</strong> ma<strong>in</strong>ly centred on IVIG and Factor VIII (<strong>in</strong>cl. recomb<strong>in</strong>ant), as<br />

described below:

With<strong>in</strong> th<strong>is</strong> market, IVIG demand has ra<strong>is</strong>ed dramatically s<strong>in</strong>ce 2001, as described<br />

below.<br />

<strong>The</strong> slower <strong>in</strong>crease of demand between 2004 and 2007 (+21%) <strong>is</strong> ma<strong>in</strong>ly due to a<br />

political problem (see below). Th<strong>is</strong> very last figure of the table should not be<br />

representative of further development of the Brazilian market.<br />

Given Brazil’s absence of self-sufficiency, the Brazilian Federal Government, but also<br />

several federate states (eg State of Rio-de-Janeiro, State of Sao Paolo, etc..) launched<br />

<strong>in</strong>ternational public tenders, <strong>in</strong> order to fulfil the population’s needs. Between 2003 and<br />

today some problems occurred <strong>in</strong> the supply of plasma products, ma<strong>in</strong>ly because of the<br />

2003 scandal also known as the “vampire scandal” that brought corruption and illegal<br />

arrangements to light, especially between the key stakeholders of the plasma market<br />

mentioned above. Follow<strong>in</strong>g th<strong>is</strong> scandal fractionation contract that expired <strong>in</strong> 2004 was<br />

renewed <strong>in</strong> 2007 only. Th<strong>is</strong> <strong>in</strong>terruption <strong>in</strong> plasma products supply slowed down the<br />

evolution of Brazilian demand, but th<strong>is</strong> was, by def<strong>in</strong>ition, a punctual phenomenon.<br />

Brazilian will<strong>in</strong>g to reach some self-sufficiency <strong>is</strong> quite clear as it concluded an<br />

agreement <strong>with</strong> LFB to set up a fractionation plant <strong>in</strong> Brazil: a close and official<br />

partnership has been establ<strong>is</strong>hed between LFB and Brazilian state-controlled structure<br />

“Hemobras” to implement th<strong>is</strong> project and rationalize the whole collection and supply<br />

cha<strong>in</strong>.<br />

As a practical matter, the objective of th<strong>is</strong> project <strong>is</strong> to set up a fractionation plant <strong>in</strong><br />

northern Brazil, <strong>with</strong> a view to produc<strong>in</strong>g plasma-derived products, made from Brazilian<br />

plasma, <strong>in</strong> order to br<strong>in</strong>g additional volumes of plasma products and thus improve<br />

Brazil’s situation <strong>in</strong> terms of self-sufficiency.<br />

However, th<strong>is</strong> project will require some time, and self-sufficiency rema<strong>in</strong>s a very long<br />

term objective, and the level of import of plasma-derived products <strong>is</strong> likely to rema<strong>in</strong><br />

high over the next years.


126 Plasma <strong>KCE</strong> Reports 120<br />

ECONOMIC CONTEXT<br />

<strong>The</strong> sharp <strong>in</strong>crease <strong>in</strong> the demand of such products as IVIG demand illustrates the<br />

evolution of prescription habits, but also the recent ability of Brazilian citizens to<br />

purchase these products, thanks to the improvement of the Brazilian economic<br />

situation. Should th<strong>is</strong> economic trend rema<strong>in</strong> stable over the next years, th<strong>is</strong> evolution<br />

<strong>is</strong> likely to rema<strong>in</strong> comparable for the next years.<br />

CLINICAL PRACTICES<br />

In compar<strong>is</strong>on to the situation of west European countries and North America,<br />

consumption of IVIG per capita rema<strong>in</strong>s low: 5.7 g per thousand people. Should<br />

Brazilian practices conform progressively to the western standards, th<strong>is</strong> consumption<br />

would obviously evolve accord<strong>in</strong>gly and thus have a noticeable impact on Brazilian<br />

demand.<br />

FOCUS ON THE CHINESE MARKET<br />

Recent restructur<strong>in</strong>g of the Ch<strong>in</strong>ese plasma fractionation <strong>in</strong>dustry has led to a reduction<br />

of domestic production of plasma products, from 4.5 to 3 million liters <strong>in</strong> 2006. Th<strong>is</strong> cut<br />

down <strong>in</strong> Ch<strong>in</strong>ese production capacity has led to imports of Album<strong>in</strong> and recomb<strong>in</strong>ant<br />

factor VIII. Import of other plasma-derived products rema<strong>in</strong>s banned, due to the specific<br />

Ch<strong>in</strong>ese regulation framework.<br />

Cl<strong>in</strong>ical practices and coverage of medical expenditure are the ma<strong>in</strong> h<strong>in</strong>der<strong>in</strong>g factors<br />

for further development of the plasma market:<br />

• Such pathologies as haemophilia rema<strong>in</strong> under-diagnosed (1000 patients<br />

officially diagnosed ; theoretical number of patients around 100 000)<br />

• Access to modern treatments (especially plasma products) rema<strong>in</strong>s<br />

difficult for the vas majority of the population for two reasons because of<br />

the absence or the lack of health care coverage and of the ban on import<br />

of most of plasma products. <strong>The</strong>refore, many physicians still resort to<br />

cryoprecipitate, whole blood or even traditional medic<strong>in</strong>e.<br />

Ch<strong>in</strong>ese ban on import of plasma products and its impact on the market rema<strong>in</strong>s a<br />

h<strong>in</strong>der<strong>in</strong>g factor for import of a wide-range of plasma products except for recomb<strong>in</strong>ant<br />

Factor VIII and Album<strong>in</strong>. Given the <strong>in</strong>creased awareness of <strong>in</strong>novative therapy, and<br />

simultaneously domestic suppliers’ difficulty to meet the Ch<strong>in</strong>ese population’s actual<br />

needs, it <strong>is</strong> clear that Ch<strong>in</strong>a will cont<strong>in</strong>ue to import these two factors, at least over the<br />

very next years. However today’s Ch<strong>in</strong>ese legal framework, ie ban on import of IVIG <strong>is</strong><br />

unlikely to change over the very next years.

APPENDIX 6: FRANCE: PLASMA COLLECTION<br />

WITHIN THE EFS<br />

KEY FIGURES ON DONATION: TODAY’S SITUATION<br />

<strong>The</strong> number of donors has reached 1.5 and the number of donations about 2.5 million<br />

(ie about 8000 donations daily <strong>in</strong> average). <strong>The</strong> blood collected <strong>in</strong> France has enabled to<br />

carry out treatment for 500 000 patients yearly.<br />

From a political po<strong>in</strong>t of view, the ma<strong>in</strong> strengths of the system are<br />

• <strong>The</strong> tradition of donation and republican public-spiritidness.<br />

• <strong>The</strong> <strong>in</strong>d<strong>is</strong>putable v<strong>is</strong>ibility of the EFS.<br />

Conversely, the ma<strong>in</strong> limits of the system are<br />

• <strong>The</strong> relatively week proportion of donors (around 4% of the overall<br />

population).<br />

• <strong>The</strong> d<strong>is</strong>tribution of collection centres, which <strong>is</strong> largely a heritage of the<br />

past decades, but not always cost-efficient, consider<strong>in</strong>g today’s f<strong>in</strong>ancial<br />

constra<strong>in</strong>ts.<br />

PRACTICAL ORGANISATION AND ACTUAL POLICIES: KEY<br />

POINTS<br />

<strong>The</strong> website of the EFS <strong>is</strong> centralized on the national level, but <strong>with</strong> regional w<strong>in</strong>dows.<br />

All relevant <strong>in</strong>formation <strong>is</strong> <strong>available</strong> on the website, and On-l<strong>in</strong>e book<strong>in</strong>g <strong>is</strong> also <strong>available</strong><br />

and user-friendly. Field blood and plasma collection <strong>is</strong> comparable to other countries’<br />

practices, <strong>with</strong> 175 collection sites, fixed or mobile, d<strong>is</strong>tributed across the <strong>French</strong><br />

territory, both <strong>in</strong> rural and urban areas.<br />

However, mobile collection rema<strong>in</strong>s important compared to fixed collection po<strong>in</strong>ts: for<br />

th<strong>is</strong> reasons, the use of human resources and facilities <strong>is</strong> not optimized <strong>in</strong> some places.<br />

Focus on young adults<br />

Apart from traditional campaigns (comparable to other countries’ campaigns) one of the<br />

key targets of the EFS has been to focus communication on the most relevant age<br />

groups, ie young people and young adults, who are apt to become future donors, and<br />

repeat donors.<br />

Given the crucial importance of th<strong>is</strong> age group (18-26), a national competition was<br />

launched <strong>in</strong> 2008-2009. <strong>The</strong> ma<strong>in</strong> orig<strong>in</strong>ality of th<strong>is</strong> competition was to get th<strong>is</strong> age<br />

group <strong>in</strong>volved <strong>in</strong>to the design<strong>in</strong>g and the field organization of campaigns. After<br />

completion of these campaigns, the EFS has organized an <strong>in</strong>-depth evaluation of these<br />

campaigns, and rewarded the best campaigns. Three different awards have been def<strong>in</strong>ed<br />

and awarded accord<strong>in</strong>gly, based on the follow<strong>in</strong>g subjects:<br />

• Creativity award: the objective <strong>is</strong> to identify the most <strong>in</strong>novative<br />

campaign to ra<strong>is</strong>e students’ awareness of donation.<br />

• Interactivity award: the objective <strong>is</strong> to identify the campaign that<br />

resorted to widest range of media simultaneously (especially multimedia<br />

tools).<br />

• Pedagogy Award: the objective <strong>is</strong> to identify the most didactic<br />

campaign, and simultaneously the most faithful to the EFS values: voluntary<br />

and unpaid dimensions of donation, quality and best practices, non-profit<br />

dimension of EFS, etc..<br />

Th<strong>is</strong> first step campaign <strong>is</strong> now complete. A last mail<strong>in</strong>g of documents will be launched<br />

between November 2009 and April 2010, <strong>in</strong> close cooperation <strong>with</strong> the <strong>French</strong><br />

University canteens.


128 Plasma <strong>KCE</strong> Reports 120<br />

As far as private firms are concerned EFS documents (thematic documents, general<br />

<strong>in</strong>formation on donation and blood products, and one specific poster “More than<br />

colleagues …Blood Donors”..) can be downloaded free of charge from the EFS website.<br />

However, the EFS recently laid emphas<strong>is</strong> on SMEs (ie firms employ<strong>in</strong>g lesser than 500<br />

employees): a specific mail<strong>in</strong>g campaign has been launched, which addressed 50 000<br />

SMEs nationwide. <strong>The</strong> EFS obta<strong>in</strong>ed a positive answer from 500 SMEs (ie 1% of the<br />

target). <strong>The</strong>se SMEs’ data and contact details have been entered onto the databases of<br />

the different branches of the EFS <strong>in</strong> order to organize close contacts and field<br />

cooperation <strong>in</strong> l<strong>in</strong>e <strong>with</strong> local priorities: Newsletter, rout<strong>in</strong>e <strong>in</strong>formation, etc…<br />

Larger firms (above 500 employees) should be the next target of the communication<br />

campaign over the next months.<br />

However, these efforts focus on blood donation <strong>in</strong> general and not on plasma donation<br />

specifically.<br />

Information delivered to the donor<br />

As <strong>in</strong> other EU countries, the EFS website provides <strong>with</strong> key <strong>in</strong>formation on governance<br />

and values of the EFS. It also provides technical <strong>in</strong>formation on the organization of<br />

blood / plasma donation <strong>in</strong> practice: On-l<strong>in</strong>e book<strong>in</strong>g; Fixed collection centres and<br />

mobile collection.<br />

Cl<strong>in</strong>ical <strong>in</strong>formation <strong>is</strong> also <strong>available</strong> about blood groups, donation types, and the key<br />

steps of blood process<strong>in</strong>g.<br />

<strong>French</strong> population’s awareness of plasma donation<br />

However, all <strong>in</strong>formation delivered to the donor rema<strong>in</strong> very general and addresses<br />

whole blood and plasma donors alike. Plasmapheres<strong>is</strong> technique <strong>is</strong> mentioned on the<br />

website. However no specific emphas<strong>is</strong> <strong>is</strong> laid on that subject and no further<br />

<strong>in</strong>formation <strong>is</strong> provided on the technical and cl<strong>in</strong>ical dimensions of th<strong>is</strong> technique.<br />

Th<strong>is</strong> situation should draw stakeholders’ attention, as only 60% of <strong>French</strong> people know<br />

that plasma can be donated: as demonstrated by a recent survey of Cerphi Association<br />

(Etude Cerphi – Tro<strong>is</strong>ième Edition – Donner son sang en France – Cécile Baz<strong>in</strong> &<br />

Jacques Malet – Mai 2006), 202 awareness of plasma donation and plasma donation<br />

techniques rema<strong>in</strong>s poor <strong>in</strong> France compared to other k<strong>in</strong>ds of donations (whole blood<br />

but also platelets).

APPENDIX 7: GERMANY: PLASMA COLLECTION<br />

WITHIN THE GERMAN RED CROSS AND BY<br />

OTHER STAKEHOLDERS<br />

PLASMA COLLECTION WITHIN THE FRAMEWORK OF THE<br />

GERMAN RED CROSS (DRK)<br />

Selection, Follow-up and retention of donors<br />

Age-group targets<br />

In terms of target population people below 30 (and among them students and jobless<br />

people) are clearly the most important people to focus on for plasma donation, (see :<br />

Survey of Robert Koch Institute). <strong>The</strong> DRK has the contact details of all teachers<br />

work<strong>in</strong>g <strong>in</strong> relevant areas (ie sciences, biology) at its d<strong>is</strong>posal. Hence, it has the<br />

possibility to contact them very easily. Specific material dedicated to high school pupils<br />

are:<br />

• High School magaz<strong>in</strong>e: “We are heroes” focus<strong>in</strong>g on key scientific<br />

<strong>in</strong>formation and on the civic dimension of blood donation.<br />

• Experiment material: 6 different biology experiment packages on blood,<br />

blood functions, blood groups, etc...to be performed by pupils themselves<br />

<strong>in</strong> their classroom.<br />

• 12 scientific leaflets on: immune system, clott<strong>in</strong>g process, blood groups,<br />

etc..<br />

• Illustrated charts and posters on the ma<strong>in</strong> blood-related subjects.<br />

Practical follow-up of donors by the DRK<br />

Once a donor <strong>is</strong> identified and selected, h<strong>is</strong>/her data are entered onto the DRK<br />

database, and he/she <strong>is</strong> subject to:<br />

• a prec<strong>is</strong>e personal data management (onl<strong>in</strong>e updat<strong>in</strong>g system <strong>available</strong>)<br />

• a specific and very regular adm<strong>in</strong><strong>is</strong>trative follow-up: regular chas<strong>in</strong>g of the<br />

donors <strong>is</strong> performed by E-mail, Mail<strong>in</strong>gs, regular phone recruit<strong>in</strong>g.<br />

Focus: key messages of the advert<strong>is</strong><strong>in</strong>g and communication campaign<br />

• No <strong>in</strong>volvement of celebrities <strong>in</strong> the campaign: “No show-off models” <strong>is</strong><br />

the first statement put forward on the website of the DRK. DRK’s<br />

campaign focused on ord<strong>in</strong>ary people, real life situations, and real world<br />

objects.<br />

• Everyday life products and situations: the key messages first focus on the<br />

concept of shortage of renewable products and the trouble caused by th<strong>is</strong><br />

shortage, eg: the end of a toothpaste tube, the last match of the<br />

matchbox, the last drops of <strong>in</strong>k from a cartridge.<br />

Contrast between consumer products and blood (and blood products): For each of the<br />

concerned products, the message clearly refers to the possibility of buy<strong>in</strong>g the product<br />

easily and quickly (eg: “You will f<strong>in</strong>d <strong>in</strong>k cartridges <strong>in</strong> shops. But not blood”. Donate<br />

Blood / See below). By contrast <strong>with</strong> these products, specific nature of blood <strong>is</strong> clearly<br />

underl<strong>in</strong>ed, and thus the irreplaceable nature of blood donation.

Figure 16 :“Ink cartridge” Posters<br />

Source: German Red Cross Website<br />

• Connection between nature of blood and irreplaceable nature of blood<br />

donation<br />

Tone of the campaign: direct commands. One must underl<strong>in</strong>e that “Spende Blut” means<br />

“Give Blood” <strong>with</strong> <strong>in</strong>formal “you”.<br />

Target<strong>in</strong>g the donors’ social life: important to stress <strong>is</strong> the ability of to stick to the<br />

specific traits of German social and cultural life. <strong>The</strong> DRK deliberately targeted students<br />

<strong>in</strong> its campaign and selected a “Stammt<strong>is</strong>ch Picture” on one of its posters, to attract<br />

potential student donors. Note: <strong>The</strong> Stammt<strong>is</strong>ch <strong>is</strong> an old tradition <strong>in</strong> German<br />

universities: debates on a wide range of subjects (literary, philosophical, or political).<br />

<strong>The</strong> slogan <strong>is</strong> “You will f<strong>in</strong>d philosophers everywhere. Not Blood. Donate Blood!”<br />

Location of the private centres<br />

Concern<strong>in</strong>g plasmapheres<strong>is</strong> specifically, the German association of the plasma donation<br />

centres called Arge-Plasmapherese, founded 1997 (http://www.arge-plasmapherese.de/),<br />

delivers key <strong>in</strong>formation on that subject, especially on location of plasma centres:<br />

• Location of Red Cross centres and Municipal centres <strong>is</strong> largely due to<br />

h<strong>is</strong>torical reasons. Red Cross and Municipal Centres are few and their<br />

d<strong>is</strong>tribution across Germany <strong>is</strong> relatively even.


<strong>KCE</strong> Reports 120 Plasma 133<br />

• Conversely, location of private and <strong>in</strong>dustry centres has been selected on<br />

rentability-oriented criteria over the last years: rather under privileged<br />

regions: of the 60 private plasmapheres<strong>is</strong> centres reg<strong>is</strong>tered <strong>in</strong> 32 are<br />

located <strong>in</strong> the ex- Democratic Republic of Germany, 14 <strong>in</strong> North<br />

Rh<strong>in</strong>eland – Westphalia. In other words 75% of these centres are often<br />

located close to universities. It must be outl<strong>in</strong>ed that they are generally<br />

located <strong>in</strong> small / medium sized towns both for f<strong>in</strong>ancial reasons (lower<br />

start-up costs for the centre itself) and for practical reasons (Faster<br />

penetration <strong>with</strong> market<strong>in</strong>g activities, Possibility to achieve full capacity <strong>in</strong><br />

a shorter period of time).<br />

FINANCIAL COMPENSATION<br />

Even <strong>with</strong><strong>in</strong> the same umbrella organization, the level of f<strong>in</strong>ancial compensation may<br />

vary across centres. With<strong>in</strong> the organization we focused on, it ranges from 16 to 20 €.<br />

<strong>The</strong>refore, th<strong>is</strong> compensation <strong>is</strong> not just a compensation but also part of costs<br />

management. Specific f<strong>in</strong>ancial compensation <strong>is</strong> provided to first donors: 38€ <strong>in</strong> most<br />

centres.

plasma supplied by the ARCBS and provid<strong>in</strong>g plasma products back to the ARCBS for<br />

further d<strong>is</strong>tribution. CSL Limited has to assume on many po<strong>in</strong>ts public law obligations,<br />

as comm<strong>is</strong>sioned by the NBA (even if CSL <strong>is</strong> not a public law body).<br />

Other pharmaceutical firms<br />

More punctually, other firms can be responsible for the supply and d<strong>is</strong>tribution of<br />

specific range of products, whenever these products are not produced <strong>in</strong> Australia or<br />

when the Australian domestic capacity <strong>is</strong> not <strong>in</strong> the position to meet the patients’ needs.<br />

<strong>The</strong>rapeutic Goods Adm<strong>in</strong><strong>is</strong>tration (TGA)<br />

<strong>The</strong> TGA <strong>is</strong> an <strong>in</strong>dependent body that <strong>is</strong> responsible for regulat<strong>in</strong>g the whole sector <strong>in</strong><br />

the field of efficacy, safety standards, and quality of blood and blood products. It <strong>is</strong> also<br />

entrusted <strong>with</strong> audit<strong>in</strong>g of Good Manufactur<strong>in</strong>g Practice and product recalls (see below /<br />

Contract between CSL and the NBA).<br />

Health care professionals and suppliers<br />

<strong>The</strong> latter stakeholders also play a role, even <strong>in</strong>formally, <strong>in</strong> adv<strong>is</strong><strong>in</strong>g the NBA a number<br />

of formal or <strong>in</strong>formal work<strong>in</strong>g groups and fora on technical subjects (eg: Professional<br />

Community Forum, NBA Fellows Program, and Cl<strong>in</strong>ical Adv<strong>is</strong>ory Council).<br />

MANAGEMENT OF SUPPLY: QUICK OVERVIEW<br />

On a rout<strong>in</strong>e bas<strong>is</strong>, the NBA notifies the Australian Red Cross Blood Service annually of<br />

the volume of plasma to be supplied to CSL for fractionation. Under the terms of the<br />

Plasma Products Agreement (PPA), the NBA must give CSL the Annual Supply Estimate<br />

for a particular f<strong>in</strong>ancial year by no later than the preced<strong>in</strong>g 30 November. Although<br />

these forecasts are not b<strong>in</strong>d<strong>in</strong>g on the NBA, it <strong>is</strong> required under the terms of the PPA<br />

to purchase 95% of the plasma products produced <strong>in</strong> accordance <strong>with</strong> the Confirmed<br />

Quarterly Requirements that the NBA furn<strong>is</strong>hes to CSL six months <strong>in</strong> advance of each<br />

quarter. <strong>The</strong> NBA also needs to make sure that suppliers actually ma<strong>in</strong>ta<strong>in</strong> reserve<br />

hold<strong>in</strong>gs of products, <strong>in</strong> order to ensure that timely and adequate supplies are <strong>available</strong><br />

to meet cl<strong>in</strong>ical needs.

CRISIS AND RISK MANAGEMENT<br />

One of the day-to-day, but also strategic objectives of the NBA <strong>is</strong> to enhance the<br />

resilience and the responsiveness of the whole sector. <strong>The</strong> latter aspect <strong>is</strong> of great<br />

importance for Australia, as a specific cr<strong>is</strong><strong>is</strong>-management framework has been def<strong>in</strong>ed<br />

by the NBA.<br />

• Likelihood of a supply / demand cr<strong>is</strong><strong>is</strong> <strong>is</strong> identified by the NBA and<br />

entered onto a specific table [1: rare – 5: almost certa<strong>in</strong>].<br />

• Consequence of a cr<strong>is</strong><strong>is</strong> <strong>is</strong> also identified by the NBA and entered onto a<br />

specific table [1: M<strong>in</strong>or consequences / Buffer stock – 5: Catastrophe /<br />

Widespread national outage, Blood stocks below 24h].<br />

Thanks to the comb<strong>in</strong>ation of the two scales mentioned above, a r<strong>is</strong>k matrix has been<br />

set up to assess the overall r<strong>is</strong>k rate, ie the seriousness of the cr<strong>is</strong><strong>is</strong>. Follow<strong>in</strong>g th<strong>is</strong> r<strong>is</strong>k<br />

assessment process, a specific framework has been set out to def<strong>in</strong>e preparation and<br />

mitigation of supply or demand cr<strong>is</strong><strong>is</strong>. <strong>The</strong> NBA has def<strong>in</strong>ed strategies to m<strong>in</strong>im<strong>is</strong>e the<br />

impact of such cr<strong>is</strong>es based on r<strong>is</strong>k management plans <strong>in</strong> supply contracts, cooperation<br />

<strong>in</strong> supplier cont<strong>in</strong>gency plann<strong>in</strong>g, product reserves and cont<strong>in</strong>gent supply arrangements,<br />

promotion of best practice of blood and blood products and improvement <strong>in</strong> <strong>in</strong>ventory<br />

management and <strong>report</strong><strong>in</strong>g. Should these measures not be sufficient, further measures<br />

can be considered on the national level (Department of Health).<br />

KEY SUCCESS FACTORS FOR A RELIABLE SUPPLY POLICY<br />

• Provid<strong>in</strong>g the Australian governments (national and federate level) <strong>with</strong><br />

accurate and timely <strong>in</strong>formation for dec<strong>is</strong>ion-mak<strong>in</strong>g.<br />

• Close and day-to-day partnership <strong>with</strong> suppliers, <strong>with</strong> a view to address<strong>in</strong>g<br />

supply cha<strong>in</strong> gaps.<br />

• Close partnership <strong>with</strong> the cl<strong>in</strong>ical community to enhance the<br />

development of EB guidel<strong>in</strong>es, standards, and programs for improv<strong>in</strong>g<br />

patient outcomes.
