abstract: Hemostasis was studied in 55 patients with myeloma, grouped in three groups according to the clinical stage of the disease. Thrombocytic adhesion, aggregation, activity of TF3 and TF4, of antithrombin III, FMDC level, FDP titre and fibrinolysis test were determined on the background of the screening coagulation tests. The studies were carried out before the treatment and were followed up after the therapeutic response or in the absence of improvement. Thirty per cent of the patients had manifestations of hemorrhagic diathesis, and 5 per cent - thromboembolism. Essential hemostatic deviations were found: progressive thrombocytopenia and thrombopathia and DIC syndrome that correlate with the stage of the disease, being most severe among the stage III patients. The patients that responded to the treatment had a great part of the hemostatic disorders corrected, and in case of no effect from the treatment - the deviations persisted, intensified and in 5 of the patients were responsible for the fatal end. The pathogenesis of the hemostatic deviations is complex and is associated with the characteristics of the basic disease and the concomitant complications.
