Procedure: platelet transfusion
Registration Number
NCT05399693
Lead Sponsor
Institut de cancérologie Strasbourg Europe
Brief Summary

Platelet Transfusion Refractoriness is one of the severe complications after multiple transfusions in patients with severe thrombopenia. Platelet Transfusion Refractoriness is characterized by inefficient transfusion and arise from allo-antibodies specific of platelets antigenes, mostly carried by HLA-I molecules.

Detailed Description

A preliminary study has shown different isotypes of anti-HLA I in patients with Platelet Transfusion Refractoriness. Our hypothesis is that the type of anti-HLA I antibodies (recognised epitope, quantity, isotype) should establish predictive and diagnostic criteria for Platelet Transfusion Refractoriness.
