A severe nonhemolytic transfusion reaction occurred to a polytransfused leukemic patient as a life-threatening anaphylactic shock with cardio-pulmonary arrest following the transfusion of HLA-nonadapted/mismatched platelets. As the only potential causative agent a lymphocytotoxic antibody with the specificity anti-HLA-A2 has been found. The HLA antibody reacted up to a dilution of 1:2,048. The recipient was negative for the corresponding antigen, but HLA-2 was present on donor's platelets. This observation demonstrates again the clinical value of HLA-matched platelet transfusion in patients who need long-term support.
