Previous studies have demonstrated that plasma tissue plasminogen activator (t-PA) level was elevated in patients with liver disease. In this study, t-PA antigen levels were investigated in patients with acute hepatitis (AH; N = 12), chronic hepatitis (CH; N = 8), compensated liver cirrhosis (CLC; N = 40), decompensated liver cirrhosis (DLC; N = 23) and hepatocellular carcinoma (HCC; N = 35). The increased t-PA levels (higher than 14 ng/ml) were found in 33% (4/12) of AH on the early hospital days, 25% (2/8) of CH, 45% (18/40) of CLC and 91% (21/23) of DLC, and 60% (21/35) of Hcc cases. In patient with LC, the correlations between t-PA levels and serum total bilirubin (T.Bill) and hepatic synthetic functions were investigated. The results were that the t-PA levels correlated positively with T. Bil and negatively with liver synthetic functions such as albumin, protein C and choline-esterase, indicating that t-PA increased almost in proportion to the deterioration of hepatic function. Serial determination of t-PA in patients with HCC treated by transcatheter arterial embolization (TAE) revealed that TAE failed to normalize the t-PA levels. In one case of HCC complicated with disseminated intravascular coagulation (DIC), t-PA showed a marked increase at acute phase of DIC and subsequent decrease after the successful treatment for DIC by gabexate mesilate (FOY) infusion. These results suggest that increased t-PA in liver disease is due mainly to deterioration of hepatic function, and that secondary fibrinolytic state, such as DIC, is also a contributing factor.

Fibrin(ogen) degradation product (FDP) and D-dimer levels were evaluated in 168 liver cirrhosis (LC) patients without evidence of bleeding. Eighty-two (48%) had FDP higher than 10 micrograms/ml; only 43 of them had a concomitant increase of D-dimer. These alterations were more frequent in older and decompensated patients and correlated to the Child-Turcotte score. In the patients with elevated FDP and/or D-dimer levels the mean values of platelets, prothrombin activity and fibrinogen were not significantly different from those of the other patients and remained fairly stable over the period of the study. Finally, an increase of FDP is frequent in LC and this may suggest a diagnosis of disseminated intravascular coagulation (DIC), but a concomitant increase of D-dimer is rarely detectable, thus excluding this diagnosis. Moreover, even in the cases with increased levels of D-dimer the presence of clinical or laboratory evidence of a consumption coagulopathy, expression of a manifest DIC, seems to be unusual.

Haemostatic functions in 30 cases of cirrhosis liver (18 bleeders and 12 non-bleeders) irrespective of the type of cirrhosis were studied. All the cirrhotics were found to have normal bleeding and clotting time. Thrombocytopenia was observed in 10 cases (33.3 percent), reduced availability of PF3 in 8 cases (26.6 percent), multiple coagulation factor defects in 18 cases (60 percent), increased euglobulin lysis activity in 8 cases (26.6 percent) and low plasma fibrinogen in 12 cases (40 percent). The combination of these tests indicated consumption coagulopathy with secondary fibrinolysis as the major contributory factor in haemorrhagic diathesis in patients with cirrhosis of liver. These coagulation defects were found to be more severe in bleeders than non-bleeders.

Measurement of Protein S in human plasma is clinically important because of deficiency of this protein, which functions as a cofactor of the naturally occurring anticoagulant activated Protein C, is a risk factor for venous thromboembolism. We describe a two-site, enzyme-linked immunosorbent assay (ELISA) for measuring Protein S in which a monoclonal IgG directed against the calcium-independent conformation of Protein S is the capture antibody. The range of detection for the assay was 10 to 160 ng of Protein S per milliliter. The coefficients of variation were 4.6%-7.3% within-assay and 7.7%-10.1% between-assay. We compared this assay with an ELISA involving a polyclonal anti-Protein S rabbit IgG as capture antibody (I) and with Laurell's electroimmunoassay (II) to measure Protein S in plasma from 32 normal subjects and 121 patients or individuals expected to have low concentrations of total Protein S (full-term newborns, pregnant women after the 18th week of gestation, patients with disseminated intravascular coagulation or liver cirrhosis, patients receiving therapy with warfarin, and patients with congenital Protein S deficiency). In general, the results obtained with the monoclonal antibody-based ELISA correlated well with those from I (r = 0.94), less well with those from II (r = 0.86).

Thrombin-antithrombin III complex (TAT) and Plasmin-alpha 2 plasmin inhibitor complex (PIC) were examined in fifty two cases of various chronic liver diseases. TAT was significantly elevated in cases of hepatocellular carcinoma (HCC), but PIC did not show significant changes in any chronic liver diseases. Elevations of TAT and PIC were seen in cases of HCC accompanied by tumor enlargement and extensive tumor thrombosis. In cases of HCC undergoing transcatheter arterial embolization (TAE), TAT and PIC increased on the next day after TAE, and tended to recover with time, returning to almost normal at fourth week. Prolongation of prothrombin time, elevation of FDP and positive FM test were noted more often in liver cirrhosis with disseminated intravascular coagulation (DIC) than in severe liver dysfunction without DIC. Of five cases confirmed as DIC, only three cases were diagnosed as DIC by DIC score. On the other hand, TAT and PIC were significantly elevated in DIC cases. Especially, TAT exceeded 30 ng/ml in all DIC cases. TAT was regarded to be useful for the diagnosis of DIC in severe liver dysfunction.

Platelet abnormalities associated with hepatobiliary diseases include increased (thrombocytosis) and decreased (thrombocytopenia) numbers of platelets as well as abnormalities in function (thrombocytopathy or thrombasthenia). Hepatic diseases that are accompanied by platelet abnormalities include hepatitis, cirrhosis, portal hypertension, and neoplastic disorders both benign and malignant. The objective of this work is to examine the platelet abnormalities that occur with a variety of hepatobiliary disorders. Thrombocytosis is seen as a reactive entity following splenectomy. Thrombocytopenia is associated with hypersplenism, dysproteinemias and liver disease related disseminated intravascular coagulation (DIC). Qualitative platelet abnormalities are found in hepatic failure, liver diseases associated with high or low levels of lipid, and with medications given for a variety of hepatocellular diseases. Clinically common and significant platelet abnormalities associated with liver disease are thrombocytopenia secondary to portal hypertension and the thrombasthenias following metabolic changes and/or therapeutic interventions of liver disease.

Since 1984 the peritoneovenous shunt has been installed in 33 patients (10 females - 30.3%; 23 males - 69.7%) of the average age of 54 +/- 8, all in the phase of therapeutically resistant ascites (alcoholic cirrhosis 28 - 84.85%; 4 - 12.12% posthepatitic cirrhosis; and 1 - 3.03% hepatic amyloidosis). The control group consisted of 39 patients (11 females - 28.2% and 28 males - 71.8%) treated in an identical time span with the strict conduction of medicament-diet therapy. The aim of this study was to check the value of this method on our own clinical-patient material, and therefore establish the incidence of complications. By the use of a unique protocol we followed mortality, morbidity, body weight, belly circumference, diuresis, the ultrasonographic finding of the abdominal cavity and the complications which appeared. Out of the group operated on 19 (57%) of the patients died, and so did all the control group patients as well. The average life duration was 275 +/- 810 days in the group operated on, and 44 +/- 29 (p less than 0.005) in the control group. All those alive (14.33-42.42%) lived longer than six months. Six patients lived longer than one year (42.85%), 4 (28.47%) longer than two years, and one (7.14%) longer than three years. There is a statistically significant decrease in body weight, belly circumference, diuresis increase and the consequent ascites withdrawal. DIC occurred in 2 patients, shunt malposition in 2, saccular dilatation in 1, plastic peritonitis in 6, and ileus in 1 patient. Not one of the listed complications resulted by death.(ABSTRACT TRUNCATED AT 250 WORDS)

The detection of TATC may inform about the presence of thrombin generation and, and hence of a pre-thrombotic status. An ELISA test (Enzygnst TAT) has been developed here in order to evaluate the predictive role played by TATC, and it was applied on 182 patients who distributed in 14 with cirrhosis of the liver, 11 with sepsis, 17 with chronic arterial insufficiency, 55 with neoplasms, 9 with thrombosis, 15 in postoperative period, 15 with pneumonia, 16 with disseminated intravascular coagulation (DIC), 14 with multiple injuries and 16 with pancreatitis. TATC levels were significantly increased in all groups with regard to the control group. Patients with thrombosis, sepsis, multiple injuries, DIC and in the postoperative period showed especially high TATC figures. No correlation between TATC and fibrinogen, platelet count, activated partial thromboplastin time or prothrombin complex assay was found in the post-operative patient-group. It was concluded that TATC are a good indicator of hypercoagulability.

Laboratory diagnosis of disseminated intravascular coagulation (DIC) in liver cirrhosis (LC) could be complicated by the presence of the usual decrement of the hemocoagulative parameters and of an increase of the fibrinogen/fibrin degradation products (FDP). The D-dimer test, more sensible than the one for FDP and specific for the cross-linked fibrin degradation products is now available. A significant difference between the two tests, assayed simultaneously has been demonstrated in 217 LC patients, without any recent or present hemorrhagic signs. The D-dimer was increased in only 60 of the 108 patients with high values of FDP; therefore this test has a screening value higher than FDP. If only the D-dimer is elevated, the FDP assay is indicated: if FDP are normal a thrombosis may be present and, finally, if the FDP are also increased with a concomitant decrement of fibrinogenemia, the laboratory diagnosis of DIC is reasonably certain.

Management of cirrhosis with massive ascites involves particular difficulties. The introduction of a peritoneovenous shunt and reinfusion of concentrated ascitic fluid techniques allows increased diuresis and improves renal function. However, these procedures have frequently been associated with disseminated intravascular coagulation and/or activation of fibrinolysis. Factor VIII activity, antigen and ristocetin cofactor, plasminogen, antiplasmin, plasminogen activator activity and plasmin-antiplasmin complex were investigated both in the ascitic fluid and plasma of cirrhotic patients before and after the concentration-reinfusion technique. Our results indicated that no hyperfibrinolysis was seen in the plasma of cirrhotic patients and that activation of fibrinolysis exists in ascites. Significantly higher levels of plasmin-antiplasmin complex and plasminogen activator activity were found in ascitic fluid than in plasma. In post-reinfusion much higher levels of all three Factor VIII components were observed in cirrhotic plasma than in normal plasma. In conclusion, activation of fibrinolysis could explain coagulation complications occurring after ascites reinfusion. Antifibrinolytic treatment could render the concentration-reinfusion technique more acceptable.
