Residual risk and retrospective analysis of transfusion-transmitted bacterial infection reported by the French National Hemovigilance Network from 2000 to 2008.

Background: Regarding blood safety, transfusion-transmitted bacterial infection (TTBI) remains the most frequent infectious risk. The incidence of these episodes needs to be assessed and updated frequently to accurately manage this risk.

Study Design And Methods: TTBIs were reported by the French network of local correspondents in each hospital and blood center.

Transfusion-related acute lung injury: reports to the French Hemovigilance Network 2007 through 2008.

Background: Transfusion-related acute lung injury (TRALI) is a major cause of transfusion-related mortality and morbidity. Epidemiologic studies using data from national transfusion schemes can help achieve a better understanding of TRALI incidence.

Study Design And Methods: A multidisciplinary working group analyzed TRALI cases extracted from the French Hemovigilance Network Database (2007-2008).

Epidemiology of Transfusion Related Acute Lung Injury in France: Preliminary Results.

SUMMARY: The French Hemovigilance Network has been established in 1994 and records all adverse events associated with the transfusion of a labile blood products (LBP) regardless of their severity. From 1994 to 2006 35,423,172 LBP were issued, 85,812 adverse transfusion reactions notified, and 139 cases of transfusion related acute lung injury (TRALI) observed. The LBP most at risk is fresh frozen plasma (FFP), followed by platelets concentrates (PC) and packed red cells (PRC).

[Haemovigilance donors: methods and results].

There is no official definition of haemovigilance donors. However, it concerns the observation and management of Serious Adverse Events observed in blood donors (SAEDs), Post Donation Informations (PDI), and donor epidemiologic survey. The French Decree of 1 February 2006 imposes the declaration of the SAEDs.

Transfusion related acute lung injury (TRALI) caused by red blood cell transfusion involving residual plasma anti-HLA antibodies: a report on two cases and general considerations.

TRALI is considered a serious hazard among immune complications of blood transfusion and its occurrence is admitted to be globally underestimated. Each type of blood product is likely to cause TRALI. We report here on two consecutive observations of TRALI caused by red blood cell concentrates, in which anti-HLA class I and class II antibodies resulting from post-gravitational allo-immunization were evidenced in donors.

The French Haemovigilance System: organization and results for 2003.

In 1993 by law, in France, haemovigilance became a national system of surveillance and alert, from blood collection to the follow-up of the recipients, gathering and analysing all adverse events of blood transfusion in order to prevent their recurrences. In 2003, 2911 incidents with strong imputability have been specially analysed, among them seven confirmed cases of bacterial contamination, 137 incorrect blood components transfused with 12 cases of ABO incompatibility, 15 adverse reactions diagnosed as TRALI and 12 deaths. The analysis of information provided by haemovigilance has led to the implementation of new guidelines.

Hemovigilance network in France: organization and analysis of immediate transfusion incident reports from 1994 to 1998.

Background: Hemovigilance networks have been introduced in several countries to improve knowledge of blood transfusion-related morbidity and mortality. The general organization of the French network and its results from 1994 through March 1999 are presented here.

Study Design And Methods: The hemovigilance network relies on blood transfusion centers and hospital correspondents, who analyze unexpected and untoward blood transfusion-related effects and transmit a Transfusion Incident Report (TIR) to a national database (Transfusion Incident Reports Electronic Data Management [GIFIT]).
