Thrombocytopenic patients, who displayed hemostatic disorders and had been previously sensitized by repeated blood transfusions and/or pregnancies, were supported for surgical procedures by platelet transfusions obtained from a single ABO and HL-A matched donor by the use of continuous collection centrifugation. Because of the low incidence of HL-A identical donors, compatibility was assessed by known serologic cross-reactivity of the HL-A determinants. In three cases repeated platelet transfusions had excellent in vivo survival, and sensitization could not be detected by a battery of immunological assays. In one case there was immune sensitization and refractoriness to repeated platelet transfusion, as documented by accelerated in vivo destruction of donor and third-party platelets bearing the disparate factor HL-A8. Although serologic tests for lymphocytotoxic and leukoagglutinating antibodies were negative, the patient displayed cellular immunity in leukocyte aggregation and cell-mediated plateletolysis tests. The single donor, continuous collection technique appears to have the technical advantage of rapid, efficient collection and the immunological benefit of a restricted spectrum of allosensitization.
