Dengue seroprevalence in the French West Indies: a prospective study in adult blood donors.

Using an anti-dengue immunoglobulin G (IgG) indirect enzyme-linked immunosorbent assay, seroprevalence was determined among 783 adult blood donors in the French Caribbean islands of Guadeloupe and Martinique in 2011. Overall, 93.5% [91.

[Study of the satisfaction of the quantitative and qualitative needs of labile blood products' recipients in non self-sufficient transfusion area].

This retrospective study over 4 years, in a non-self-sufficient transfusion region, analyses the qualitative and quantitative needs of recipients of blood components in the phenotypic characteristics red cell specific. If the quantitative needs were still covered with the national solidarity, is not less that a qualitative improvement of supply remains to achieve and requires a collective effort of each of the links in the regional transfusion chain.

[Identification of alloantibodies and their associations: balance sheet of a year at the Auvergne-Loire French Blood Establishment].

Objectives: Some alloantibodies and their combinations can lead to delays or even an impasse in a transfusion, owing to the necessity of finding compatible red blood cell concentrates. The aim of this study was to determine the specificities of the most common alloantibodies, as well as the most common combinations of alloantibodies.

Methods And Materials: A retrospective study analysed erythrocyte alloantibodies identified in 2008 in the immunohematology laboratories at the Auvergne-Loire French Blood Establishment.

[Evaluation of continuous education in transfusion for professionals in medical blood banks].

Purpose Of The Study: Like every actor in transfusion, staff members practising within blood banks of healthcare establishments have to follow a specific initial training and must frequently update their knowledge in blood transfusion.

Methods: To address this need from these professionals, the Établissement français du sang Auvergne-Loire set up training sessions which content regularly evolved according to regulation recommendations. Every cycle consists in a total of 35hours of training, divided in five one-day modules.

[Analysis of a severe septic transfusion reaction with standard platelet concentrate].

We recently observed a near fatal case of transfusion-transmitted infection with standard platelet concentrate. Streptococcus dysgalactiae subspecies equisimilis was isolated both from donor, residual component container and cultures of the patient's blood. This should question the usefulness of systematic bacterial detection in platelet concentrates, however a lethal accident has occurred recently which escaped bacterial detection.
