[Apoptosis of mononuclear cells and dead leukocytes in venous blood of septic patients].

Apoptosis of mononuclear cells, dead leukocyte and CD95+ lymphocytes content in venous blood of 15 patients were evaluated by flow cytometry within 2-3 day after diagnosis of sepsis. The number of CD95+ lymphocytes increased in 40% of the cases and that of lymphocytes expressing Fas receptor decreased in 27%. The number of mononuclear cells in venous blood increased 7 times compared with physiological norm; this rise was a reliable predictor of the unfavourable outcome of the disease. Elimination of dead leukocytes by granulocytophoresis produced good therapeutic result.
