With the aim of temporarily assisting deterioration of liver function developing after surgery, extracorporeal blood purification therapy (EBPT) (plasma exchange and/or hemofiltration) was carried out in 26 postoperative patients. Initiation of EBPT was instituted according to the criteria of either a serum bilirubin greater than 15 mg/dl or Grade 2 or more coma. Plasma exchange was carried out 235 times in 23 patients and hemofiltration was performed 28 times for seven patients. In addition, hemodialysis and CAPD were linked in eight cases. Plasma exchange was found to control the progression of DIC and endotoxemia. Nine patients (35%) were weaned from EBPT. In the survivors the levels of blood ammonia and number of major complications were significantly lower compared to the nonsurvivors. Three patients treated only with hemofiltration were all lost. Among co-morbid factors present, incidences of renal failure, respiratory failure, and associated liver cirrhosis significantly increased poor clinical outcome on EBPT for postoperative liver failure.

Using a new rapid coagulant method, protein C activity (PC act) was determined in liver cirrhosis and malignancies and compared with PC antigen and AT III values. PC was decreased in a more pronounced manner than AT III in liver cirrhosis, mainly due to impaired synthesis. This is of special clinical interest because PC proved to be a high sensible indicator of liver cell dysfunction. Decreased levels of PC act (PC ratio act/ag less than 1) in decompensated liver cirrhosis may be caused by the synthesis of dysfunctional PC and/or vitamin K deficiency with production of undercarboxylated PC most sensitively registered by this coagulant assay. An increased clearance of in vivo activated PC induced by DIC may play an insignificant role. In patients with liver metastases, PC act (but not AT III and immunological parameters) was significantly reduced, supporting the conclusion that in these patients liver dysfunction concomitant with synthesis of dysfunctional PC must be discussed as the main cause of this alteration.

Greenfield filters for prevention of pulmonary emboli may be placed in the inferior vena cava by surgical cutdown or by percutaneous insertion through the femoral or jugular veins. We evaluated the use of the percutaneous techniques 52 times in 50 patients. The right femoral vein was used in 37 of the procedures, the right internal jugular vein in 12, and the left femoral vein in three. Twenty-two patients had altered coagulation factors: 11 were receiving heparin, four were receiving warfarin sodium, six had hepatic cirrhosis, and one had disseminated intravascular coagulation and had been receiving warfarin sodium. Filter placement was successful in 51 of 52 procedures. In the unsuccessful case, placement was attempted via the left femoral vein; the carrier could not be advanced from the common iliac vein to the inferior vena cava. This patient required surgical occlusion of the cava. There was one major complication, a hematoma in the right side of the groin that required transfusion. This occurred in the patient with disseminated intravascular coagulation who had extensive scarring from multiple previous vascular surgical procedures. Two patients required second filters because of severe angulation of the filter found 1 and 4 days after implantation. Clinical thrombosis of the femoral vein after femoral vein access occurred in two (5%) of 40 patients and was proved by venogram in one. Our experience shows that the percutaneous method is highly successful and suggests that this technique should be the primary method for filter placement in the inferior vena cava.

Reports in the literature on the difficulty of differential diagnosis between Disseminated Intravascular Coagulation (DIC) Pseudo-DIC and Primary Fibrinolysis (PF) in patients with liver disease, stimulated a study of various coagulation parameters (PT, PTT, Platelets, Fibrinogen, FDP) in 28 cirrhotic patients. The study confirmed reports in the literature on the high incidence of circulating FDP among liver disease patients. The vital role these play in maintaining alterations in haemostasis means that cirrhosis cases must be approached with extreme caution, avoiding any therapeutic or instrumental procedure liable to worsen the already disturbed coagulation pattern in such patients.

A simple assay method of heparin cofactor II (HC II) activity is described. The procedure is based on the following principle: Antithrombin III (AT III) in plasma is inactivated by addition of an IgG fraction of goat serum after immunization of the animals against human AT III. Complete inactivation of AT III could be shown by absence of an anti Xa-effect of heparinized plasma treated with this antibody. Thrombin was only partially inhibited after inactivation of AT III. The characteristics of this inhibition were typical for the action of HC II. This method was applied for an assay of HC II activity. After optimizing of the method practical application in clinical routine screening was carried out. A diminution of HC II was observed in liver cirrhosis and in DIC but not in AT III deficiency. In 15 out of 269 cases of recurrent DVT there were HC II activities below 70% of normal. In 4 out of these patients activities of HC II were repeatedly between 44% and 52%. In arterial obstructive disease there was an HC II activity of less than 60% in 18 out of 583 patients and in 11 of them the HC II levels were repeatedly between 45% and 54%.

Increased serum fibrinogen degradation product (FDP) in liver cirrhosis and hepatic carcinoma as measured by latex agglutination was analyzed by means of SDS-polyacrylamide gel electrophoresis followed by immunoblotting with anti-fibrinogen antibody. The antibody used in this study reacts with fibrinogen, fragment X, Y, D-D, D and E. The validity of this technique was confirmed by the analysis of the serum samples from patients with definite diagnosis of disseminated intravascular coagulation. Serum samples of 14 patients out of 18 with elevated FDP values and severe liver diseases were shown to contain no plasmic digest of fibrin or fibrinogen. By using the SDS-gel electrophoresis after disulfide bond reduction, seven serum samples from these 14 patients, who were shown to have no plasmic digest in serum, were found to contain unclottable fibrinogen retained in sera, while the remaining seven samples were revealed to have fibrin monomer in their sera. Four serum samples from the 18 patients were shown to have plasmic digest of fibrinogen, but these patients had additional diseases leading to intravascular coagulation.

A study of 93 patients with liver cirrhosis showed that the most important blood coagulation disorder in this pathology resulting in hypocoagulation, was not decreased synthesis and deficit of the prothrombin complex factors but disturbance of the final stage determined by afibrinogenemia. Considerable depression of XIIa-kallikrein-dependent fibrinolysis and marked increment of an antiplasmin level in the plasma were noted. Positive paracoagulation tests were revealed in 57% of the patients, and as other signs typical of the lingering DIC-syndrome were absent, they were interpreted as the "hypercoagulation syndrome" or "pre-DIC syndrome". The problem of possible relationship of development of both thromboses and hemorrhages with acquired afibrinogenemia in liver cirrhosis was discussed.

The blood level of endotoxin after operations in patients with digestive diseases, mainly liver cirrhosis and obstructive jaundice, and the complications most likely related to the presence of endotoxemia were investigated. Twenty-seven patients without either liver cirrhosis or obstructive jaundice showed a minimal elevation of the endotoxin level in blood, as shown by 6.1 +/- 3.9 pg/ml at the first postoperative day and there was only one anastomotic leakage. On the other hand, 18 patients with liver cirrhosis showed a notable and persistent endotoxemia after surgery. The cirrhotic patients who especially underwent splenectomy and hepatectomy showed marked elevations of endotoxin level at the first postoperative day, with values of 151.0 +/- 46.1 pg/ml and 101.3 +/- 36.2 pg/ml, respectively, and one of these patients died of hepatic failure. Thirteen patients with obstructive jaundice developed endotoxemia evidenced by the value of 21.6 +/- 4.8 pg/ml at the first day after surgery. Among these patients, two had gastrointestinal bleeding and one developed DIC. The markedly high and persistent levels of endotoxin in patients with liver cirrhosis or obstructive jaundice may be possibly related with the development of MOF.

Blood platelets were assayed in 56 cirrhosis patients divided into two groups: alcoholic cirrhosis (20 cases) and non-alcoholic cirrhosis (36 cases). Each group was also divided into two sub-groups: with and without clinical signs of portal hypertension. Low platelet counts were found in both groups (greater than 70%), the incidence being high in the sub-group with clinical signs of portal hypertension. Alcohol appeared to have no influence on the development of platelet insufficiency which was rather correlated with the severity of the hepatopathy, the presence of splenomegaly (splenic sequestration), immunological factors, (presence of circulating antiplatelet antibodies) and "consumption" phenomena (significant incidence of circulating FDP, and indicator of chronic Disseminated Intravascular Coagulation).

Increased fibrinopeptide A (FPA) levels have been reported in various non-thrombotic disorders, including cancer, acute myocardial infarction, liver cirrhosis and collagen vascular diseases. To investigate the significance of these findings, the present study combined the radioimmunoassay of FPA with that of fibrinogen/fibrin degradation fragment E (FgE) in the aforementioned disorders and compared the results with those observed in healthy subjects as well as in patients with thromboembolism and overt disseminated intravascular coagulation (DIC). Mean FPA and FgE in malignancy were 6.3 and 305 ng/ml, in myocardial infarction 5.6 and 98 ng/ml, in liver cirrhosis 2.7 and 132 ng/ml and in collagen vascular diseases 5.6 and 142 ng/ml. All these values were significantly higher than in healthy controls (mean FPA 1.6 ng/ml, mean FgE 49 ng/ml) but significantly lower than in thromboembolism (mean FPA 10.7 ng/ml, mean FgE 639 ng/ml). and DIC (mean FPA 22.0 ng/ml, mean FgE 1041 ng/ml). The overall correlation between FPA and FgE was highly significant. However, different disorders showed peculiar patterns in FPA, FgE and fibrinogen levels. In malignancy, a definite increase of FPA, FgE and plasma fibrinogen levels was observed. This finding probably indicates a compensated state of (intra- or extravascular) fibrin formation and lysis. Acute myocardial infarction was characterized by a high FPA to FgE ratio, which is interpreted to reflect acute thrombin generation and fibrin formation. FPA in cirrhosis was only marginally elevated with most single values within the normal range, indicating that intravascular coagulation was infrequent and unimportant in quantitative terms.
