[Transfusion of leukocytes and platelets in the treatment of acute leukemia]

Supportive therapy of concentrated leukocytes and platelets has no obvious significance. In the paper authors presented the methods of separation of concentrated leukocytes and platelets, investigation of number and functional abilities of preserved leukocytes and platelets as well as the monitoring of the transfusion effect in the patients with acute myeloblastic leukemia. Special attention was paid to the separation of blood cells by the cell centrifuge with continuous flow. Side effects after leukocytes and platelet transfusion was monitored -- occurence of the sensibilization to the HL-A antigens. For the detection of HL-A antibodies two-stage microlymphocytotoxic test was used for the investigation of patient's serum; for the application of leukocyte and platelet transfusion we used cross-match test between donor's lymphocytes and patient's serum in progressive dilution. In the paper authors discussed the correlation between the appearance of HL-A antibodies and the number of given transfusions.
