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 />
1. Guilla<strong>in</strong>-Barré syndrome (and variants)<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)
