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.
