Changes in plasma levels of prothrombin fragment F 1 + 2 in cases of disseminated intravascular coagulation.
Plasma levels of prothrombin fragment F 1 + 2 (PTF) and thrombin-antithrombin III complex (TAT) were assayed in 86 cases of disseminated intravascular coagulation (DIC). A significant elevation of both parameters was observed in most cases of DIC, which suggested that the in vivo generation of thrombin is highly accelerated by the cleavage of the prothrombin molecule by factor Xa. On the contrary, no significant elevation of plasma levels of PTF was observed in cases of DIC with severe hepatic failure or fulminant hepatitis in spite of significant elevation of TAT. Plasma levels of PTF were directly proportional to those of TAT in 86 cases of DIC as a whole (r = 0.682, p < 0.001). The measurement of both parameters was considered to be useful to estimate the hemostatic activation in DIC.
