title: [Classification and treatment of DIC].
abstract: Disseminated intravascular coagulation (DIC) is characterized by extreme activation of intravascular coagulation, and clinical manifestations such as bleeding and/or multiple organ failure is sometimes observed in advanced cases of DIC. The balance of coagulation and fibrinolysis activation varies according to the underlying diseases of DIC. DIC cases are classified as the type with predominant coagulation activation and the type with predominant fibrinolysis activation in former type plasma levels of thrombin-antithrombin III complex (TAT) are greatly increased, and those of plasmin-alpha 2 plasmin inhibitor complex (PIC) are slightly increased. In addition plasma levels of plasminogen activator inhibitor 1 (PA1) are greatly increased, multiple organ failure is a major clinical manifestation in advanced cases and sepsis is a representative underlying disease. In the second type both plasma levels of TAT and PIC are greatly increased, plasma levels of PA1 are almost within normal limits. Bleeding is a major clinical manifestation in advanced cases and acute promyelocytic leukemia (APL) is a representative underlying disease. The classification of DIC should be considered when choosing treatment with DIC. Diagnosis of pre-DIC status is based on gradually decreasing platelets counts in sepsis and on mild elevation of FDP and D dimer in APL, leukemia and cancer.
