Platelet transfusions from donors selectively mismatched for cross-
reactive and certain non-cross-reactive HLA antigens were found to be more
effective in HLA-A2 negative than in HLA-A2 positive, alloimmunized
thrombocytopenic patients. The two groups of patients responded equally
well to platelets matched for antigens of the HLA-A and B loci. Certain
alloimmunized patients negative for HLA-A2 continued to respond
satisfactorily to platelets selectively mismatched for non-cross-reactive
HLA antigens as long as platelets containing HLA- A2 were avoided. The data
indicate that platelet transfusion support can be provided within a broader
range of donor-recipient HLA antigenic disparity to HLA-A2 negative
alloimmunized patients than to those who are positive for this antigen.
