Abstract

Alloantibodies against RBCs after transfusion of only platelet products are rarely reported except for RhD mismatched platelet transfusion. We report a case of anti-E antibody developed after transfusion of platelet concentrates. The patient was a 27- month male infant with idiopathic thrombocytopenic purpura and was treated with IV immunoglobulin and IV Rh immunoglobulin. Anti-E antibody was detected after transfusion of 18 units of platelet concentrates for about 40 days. RBC alloimmunization was developed after transfusion of platelet products, which suggests platelet transfusion may be cause of RBC alloimmunization in childhood.
