title: [Therapeutic effectiveness of thrombocyte concentrates in relation to the results of the lymphocytotoxicity test].
abstract: The authors analyze the effect of transfusions of 211 thrombocyte concentrates to polytransfused patients in relation to the results of the crossover test between donor and recipient, using the lymphocytotoxic test (LCT). In negative LCT tests the adequate and inadequate effect was 50%. After elimination of non-immune influences (splenomegaly, febrile temperature) the percentage of adequate effects rose to 70%. In LCT positive results the effect of administration of thrombocyte concentrates declined to 30%. The authors discuss practical possibilities and ways to select suitable donors to achieve an optimal therapeutic effect of substitution therapy.
