title: French Haemovigilance Data on Platelet Transfusion.
abstract: SUMMARY: The Agence Française de Securite Sanitaire des Produits de Santé (Afssaps; French Health Products Safety Agency) is responsible, through its hemovigilance unit, for the organization and the functioning of the national hemovigilance network. In accordance with the French law, it receives all data on adverse transfusion reactions regardless of their severity. With the aim of evaluating the tolerance of two kinds of labile blood products (LBP), pooled platelet concentrates (PP) and apheresis platelet concentrates (APC), we screened the French national database from January 1, 2000 to December 31, 2006. We observed that the number of transfusion incident reports is more than twice as high with APC (8.61:1,000 LBP) than with PP (4.21:1,000 LBP). The difference between these two ratios is statistically significant as shown by chi-square test (e = 21.00 with α = 5%). The risk to suffer adverse reactions of any type, except for alloimmunization, is higher with APC, and the major type of diagnosis related to APC is allergic reaction (1:200 APC issued) even if those allergic reactions are rarely serious. The new French National Hemovigilance Commission should impel a working group evaluating this topic and above all the impact of additive solutions which have been used since 2005 to put forward preventives measures.
