Abstract

Disseminated intravascular coagulation (DIC) is a pathological state in which varying degrees of fibrinolytic activation are seen simultaneously as systemic, persistent, and marked coagulation activation in the presence of an underlying disease. Suppressed-fibrinolytic-type DIC usually develops in patients with sepsis. Coagulation activation is severe, while fibrinolytic activation is mild. Enhanced-fibrinolytic-type DIC usually occurs with acute promyelocytic leukemia (APL). Both coagulation activation and fibrinolytic activation are severe in affected patients. Balanced-fibrinolytic-type DIC is usually seen in patients with solid tumors, and has a pathogenesis intermediate between those of the two aforementioned types. In animal DIC models, lipopolysaccharide (LPS)-induced forms of DIC are similar to suppressed-fibrinolytic-type DIC, whereas models of tissue factor (TF)-induced DIC have features similar to those of enhanced-fibrinolytic/balanced-fibrinolytic DIC. We are moving in the direction of more appropriate selection of treatment based on DIC type.
