Endothelial condition and hemostasis in acute leukemia

Abstract

The review presents modern conceptions of disturbances in endothelial lining of the vessels and plasmic hemostasis in patients with acute leukemia; different mechanisms of coagulation disorders in acute leukemia: effects of leukemic cells containing procoagulants, fibrinolytic and antifibrinolytic substances, of intensive chemotherapy and inflammation. All these impacts impair endothelial cells and trigger plasmic coagulation cascade; the initiator of coagulation is a tissue factor. Mechanisms of this process and statistics of thrombohemorrhagic complications in different variants of acute leukemia are outlined.
