The following tests were performed in 15 cases of chronic aggressive hepatitis (CAH), 12 of cirrhosis, and 8 of other forms of chronic disease: liver function, thromboelastogram, prothrombin time (PT), partial thromboplastin time (PTT), determination of factors I, II, V, X and XIII, euglobulin and FDP lysis, and platelet count, shape and agglutinability. At least one haemostasis alteration was observed in nearly every case, the most common being in the thromboelastogram, PTT, prothrombin, and platelet shape and agglutinability. Defects were most marked in cirrhosis and comparison with CAH was significant in the case of PT and factor V. Fibrinolysis was increased in 60% of the CAH group and rarely elsewhere. Haemorrhage was noted in 7 cases of cirrhosis and 1 of CAH. On each occasion, it was more dependent on the serious nature of the disease, rather than defective haemostasis.

Tissue plasminogen activator (t-PA) levels in plasma or serum were studied in 416 patients with liver diseases: acute hepatitis (AH, n = 30); fulminant hepatitis (FH, n = 36); chronic inactive hepatitis (CIH, n = 57); chronic active hepatitis (CAH, n = 39); compensated liver cirrhosis (cLC, n = 78); decompensated liver cirrhosis (dLC, n = 84); hepatocellular carcinoma (HCC, n = 64); advanced hepatocellular carcinoma (aHCC, n = 28); and compared with that of a control group (n = 106) of healthy subjects. The t-PA levels showed significant increase in patients with AH, FH, CAH, cLC, dLC and HCC, compared with normal controls. The abnormal rates in t-PA levels (higher than 8.3 ng/ml) for each type of liver diseases were 86.1% in FH, 46.2% in CAH, 50% in cLC, 85.7% in dLC, 67.2% in HCC, and 89.3% in aHCC. t-PA levels tended to be higher in more advanced liver diseases. t-PA levels significantly correlated positively with plasminogen activator inhibitor (PAI-1) in AH, cLC, dLC, HCC and aHCC, and negatively with plasmin alpha 1-plasmin inhibitor complex (PIC), plasminogen (Plg), FDP, AT III and alpha 2-plasmin inhibitor (alpha 2-PI) in dLC, prothrombin time (PT) and fibrinogen (Fbg) in HCC. t-PA levels in patients with FH, CAH and dLC were significantly higher than those in patients with AH, CIH and cLC, respectively. Moreover, the changes of t-PA levels in the clinical courses of various liver diseases revealed that t-PA levels increased sensitively with progression of liver diseases or in advanced liver diseases.(ABSTRACT TRUNCATED AT 250 WORDS)

16 coagulant and 7 fibrinolytic parameters were determined in 121 normal subjects and 456 patients with various types of viral hepatitis. The results showed that plasma concentration of F VIII: c, vWF: Ag and vWF: Ag/VIII: c (P less than 0.01) were much higher than those in the controls. Plasma level of other coagulant factors was progressively reduced when the severity of hepatitis was decreased. The changes of fibrinolytic activity suggest that t-PA, PL and FDP were increased, while PAI, PLG, and alpha-PI were decreased. The results of this study may provide an experimental basis for further study of hemorrhage mechanism and prognosis in patients with viral hepatitis.

The respective roles of intravascular coagulation (DIC) and fibrinolysis were assessed in severe chronic liver disease by measuring thrombin-antithrombin (TAT) complexes, tissue-type plasminogen activator antigen (tPA Ag) and fibrinogen and fibrin degradation products (FgDP and FbDP respectively) in 66 patients with liver disease caused by cirrhosis (n = 34) or chronic hepatitis (n = 32) as compared to findings in a control group (n = 30). There was a significant increase of TAT complexes (P less than 0.01), tPA Ag (P less than 0.002), FDP and FbDP (P less than 0.001) in patients as compared to controls. FbDP increase was more evident in patients with cirrhosis than in those with hepatitis (P less than 0.01). Significant correlations between these parameters with some liver function tests were also demonstrated. Thus, in patients with severe liver disease, an increased thrombin activity, as demonstrated by high TAT levels; followed by hyperfibrinolysis suggest that a low grade DIC may occur.

Clinical and laboratory findings were studied in 56 patients with liver disease (10 acute hepatitis, 10 fulminant hepatitis and 36 cirrhosis). Spontaneous bleeding occurred in 19 patients (8 fulminant hepatitis, 11 cirrhosis) and another 8 cirrhotic patients had variceal bleeding. There were 22 deaths (36%), 12 of these patients had spontaneous bleeding. Depletion of antithrombin III (AT III) occurred in fulminant hepatitis (mean +/- S.D. = 27 +/- 16%) and cirrhosis (49 +/- 23%) but thrombin-antithrombin III complexes (TAT) were significantly higher in the former (45 +/- 22 vs 8.6 +/- 7.0 ng/ml; p = 0.006). Within subgroups of cirrhosis (with or without spontaneous bleeding or with variceal bleeding), there were no significant differences in levels of AT III or TAT. Of all patients, those with spontaneous bleeding had persistently lower AT III levels but had variable changes of other coagulation parameters (PT, PTT, TT, FDP, fibrinogen and platelet counts). This study showed that coagulopathic consumption is an important cause of AT III deficiency in fulminant hepatitis but not in cirrhosis. Serial changes in AT III levels correlated with bleeding risk in patients with liver disease.

1.286 patients were diagnosed as DIC, among 123.231 patients who were admitted in the 285 departments of the university hospitals in Japan, in 1992. The incidence of DIC was high in acute promyelocytic leukemia, fulminant hepatitis, abruptio placentae, acute respiratory distress syndrome, and sepsis. In cases of DIC, bleeding tendency due to consumption coagulopathy is most important, but organ dysfunction due to circulatory disturbances by development of multiple thrombi is also noteworthy. As a whole, DIC may be divided in two types. The first type is cases of DIC with severe bleeding symptoms. However, except cerebral hemorrhage, organ dysfunction is rare in these cases. These cases may be called as "fibrinolysis-dominant DIC", because hemostatic thrombi as well as thrombi which cause organ dysfunction by circulatory disturbances are rapidly removed by abnormally enhanced fibrinolysis. The second type involves cases of DIC with severe organ dysfunction. Bleeding symptoms in these cases are usually not severe. These cases may be called as "coagulation-dominant DIC". The most typical causative disease of the fibrinolysis-dominant DIC is acute promyelocytic leukemia. The most typical causative disease of the coagulation-dominant DIC is sepsis. The presence of causative disease of DIC, elevation of FDP, and depletion of platelet count are most important to diagnose DIC. In the treatment of DIC, removal of cause of DIC, administration of heparin to protect further development of multiple thrombi, and replacement of platelets in cases of acute leukemia are most important.
