We report a probable case of a post-transfusion purpura from homozygous sickle cell child alloimmunized against platelet antigen. We detail the challenges of alloantibody identification and transfusion management. These challenges are due to the lack of laboratory techniques for typing HLA and HPA system and the use of leukocyte-depleted (filtered) blood products.展开更多
文摘Alloimmunization to platelet antigens exposes to a serious immunological incident. We report a probable case of a post-transfusion purpura from homozygous sickle cell child alloimmunized against platelet antigen. We detail the challenges of alloantibody identification and transfusion management. These challenges are due to the lack of laboratory techniques for typing HLA and HPA system and the use of leukocyte-depleted (filtered) blood products.
