ABO compatibility and platelet transfusions of alloimmunized
thrombocytopenic patients
RJ Duguesnoy, AJ Anderson, PA Tomasulo and RH Aster
With data on 91 alloimmunized thrombocytopenic patients and 389 donor-
recipient pairs matched or selectively mismatched for HLA antigens, it was
observed that ABO incompatibility significantly reduced the effectiveness
of platelet transfusions. The mean 24-hr recovery of platelets from
histocompatible donors and from donors selectively mismatched for
cross-reactive HLA antigens was decreased by approximately 23% if the donor
typed for blood group A and/or B not found in the recipient. Thus, the
reduction in platelet recovery associated with ABO incompatibility is not
of a magnitude that would contraindicate transfusion of ABO-mismatched
platelets.
