Patients with liver disease frequently have hemostatic abnormalities which include accelerated fibrinolysis. In order to assess the fibrinolytic state in liver disease, plasma levels of fibrinogenolysis products (FgDP), fibrinolysis products (FbDP), and fibrinogenolysis plus fibrinolysis products (TDP) were measured with newly developed enzyme-linked immunosorbent assays based on monoclonal antibodies in 36 patients with liver disease (six patients with acute hepatitis, seven with chronic hepatitis, ten with liver cirrhosis, 11 with hepatocellular carcinoma, and two with intrahepatic cholestasis). As compared with healthy subjects, mean plasma levels of FbDP (1,083 +/- SD 1,254 vs. 236 +/- 100 ng/ml, P = 0.005) and TDP (1,773 +/- 1,814 vs. 669 +/- 212 ng/ml, P = 0.001) were significantly elevated in patients with liver disease, whereas FgDP was normal (389 +/- 202 vs. 396 +/- 132 ng/ml, P = 0.87). Plasma FbDP correlated very well with TDP (r = 0.986, P less than 0.00001) in liver disease. In addition, FbDP and TDP but not FgDP correlated with plasma concentrations of thrombin-antithrombin III complex. When plotted by the disease categories, the magnitude of elevations of FbDP and TDP was the most prominent in acute hepatitis followed by hepatocellular carcinoma. These findings indicate that activation of fibrinolysis occurs following thrombin generation, but increased primary fibrinogenolysis is rare in liver disease.
