ABO Blood Group Incompatibility Protects Against SARS-CoV-2 Transmission.

ABO blood groups appear to be associated with the risk of SARS-CoV-2 infection, but the underlying mechanisms and their real importance remain unclear. Two hypotheses have been proposed: ABO compatibility-dependence (neutralization by anti-ABO antibodies) and ABO-dependent intrinsic susceptibility (spike protein attachment to histo-blood group glycans). We tested the first hypothesis through an anonymous questionnaire addressed to hospital staff members.

[Blood transfusion in neonatology: Study of practical aspects in 2016 in France, excluding acute bleeding or surgical care].

Background: Blood transfusion is common in neonatology, especially in preterm or low birth weight infants. Recommendations were proposed by the French National Authority of Health (HAS) in 2014 and 2015 for red blood cells and platelet transfusion respectively, but an heterogeneity of practical attitudes persist. The objective of this survey is to evaluate transfusion practices in neonatal intensive care units.

[Analysis of causes of destruction of labile blood products in health institutions: A multicentric study].

Objective: One of the tasks of haemovigilance correspondents in Health Institutions (HI) is to reduce the destruction of labile blood components (LBC). The objective of this study was to analyse in depth, five years after a first multicentric study, the causes of LBC destruction in order to assess the impact of measures taken and to define new ways of improvement.

Methods: Prospective analysis was carried out throughout 2016.

[Is the research of posttransfusional alloantibodies still relevant?].

Unlabelled: The decision of November 6th, 2006 defining the principles of best practices recommends that posttransfusional red cell alloantibodies research is performed after one to three months after. In the University hospital of Brest, the haemovigilance unit takes charge of sending the medical prescription within the required time and centralizing the results. We wished to estimate if the realization of this research still remains relevant.

[Documents and transfusion acts: heterogeneous practices].

Blood transfusion is currently a delegated medical act in patient care services. Blood transfusion safety depends on the strict respect of processes from the prescription of blood products and required patient immuno-hematology exams to the administration of blood products and follow-up of the patient. We conducted a survey among haemovigilance correspondents to establish the documents needed to practice blood transfusion.
