In patients with liver cirrhosis, a close relationship was observed between the respective levels of antithrombin III and prothrombin, both below 50% in 20 our 27 patients. The absence of any thrombotic complication, despite low plasma antithrombin III, suggests that the preserved balance between the inhibitor and the zymogens of the inhibited enzymes could have a protective effect against thrombotic tendency.

Ascites often appears as a complication of several illnesses. The therapy is essentially based on the use of low-sodium diet, plasma or albumin infusion, diuretics and low-dosed ACE-inhibitors. To use the simple paracentesis or special techniques as Rhodiascit or Lee Veen Shunt means not to resolve definitively the problem and sometimes to cause undesirable complications. The authors present a new therapeutic tactics that joins the use of technique of double filtration of ascitic fluid and reinfusion of concentrated proteins (DFAF) with the injection in the peritoneal cavity of beta-interferon and the venous infusion of ATIII. Twenty patients affected by hepatic cirrhosis with the presence of ascitic fluid not treatable with the usual therapy have been subjected to this treatment. All the patients showed an immediate improvement of the clinical situation. After one year of observation, we describe our results. Twelve patients needed a further treatment with the DFAF technique, two patients died for the original pathology and six patients just needed an adjustment of pharmacologic therapy.

The aim of this double-blind, placebo-controlled crossover study was to investigate the effect of 1-deamino-8-D-arginine vasopressin (dDAVP) on hemostasis in patients with chronic liver disease. Nine consecutive patients with biopsy-proven liver cirrhosis and related coagulation abnormalities received in a random order dDAVP, 0.5 microgram/kg, or saline intravenously. Blood samples were taken before dDAVP infusion and 30, 60 and 180 min after its end. dDAVP infusion induced a statistically significant shortening of the bleeding time from 9 min (range 6.5-15.5) to 6 min (range 4.5-9.5) at 1 h after the infusion. The activated partial thromboplastin time was significantly shortened at 30 and 60 min after dDAVP infusion. Plasma levels of factor VIII, XI and XII coagulant activities were significantly increased at all sampling times after dDAVP infusion. The maximum increase over basal values in plasma levels of factor VIII, XI and XII was 63, 22 and 40%, respectively. dDAVP did not induce any significant changes of prothrombin time, thrombin clotting time, fibrinogen, plasma levels of factor II, V, VII, IX, X, factor XII antigen, protein C (activity and antigen), antithrombin III, plasminogen and alpha 2-antiplasmin. Placebo infusion did not produce any significant changes in the evaluated parameters. We conclude that dDAVP can positively influence the hemostatic system in patients with liver cirrhosis. The clinical relevance of this hemostatic improvement deserves further evaluation.

The blood coagulation and fibrinolysis of 33 patients with compensated liver cirrhosis and 31 patients with hepatocellular carcinoma were examined using several markers, namely thrombin-antithrombin III complex (TAT), plasmin-alpha 2 plasmin inhibitor complex (PIC), antithrombin-III (AT-III) and prothrombin time, and the relationship between these markers, endotoxemia, and TNF-alpha was examined. These patients had no complications due to hepatic failure, such as infections, encephalopathy, ascites, G-I bleeding and clinical DIC. PIC was not elevated, but TAT tended to be elevated in LC and significantly elevated in HCC. AT-III was decreased in LC and HCC, and the blood endotoxin was partly positive in LC and HCC, but was not correlated with AT-III or PT. The TAT level in the blood-endotoxin-positive patients measured by endospecy methods was higher than that in the negative patients, and was significantly correlated with the blood endotoxin level in the LC and HCC patients (r = 0.57, r = 0.88, p < 0.01). No relationship was observed between TNF-alpha and blood endotoxin. In conclusion, (1) blood coagulability was activated already in compensated LC and HCC, but was not connected with fibrinolysis, (2) the activation of coagulability was closely related with endotoxemia, and (3) TNF-alpha was not correlated with blood endotoxin or TAT.

To investigate the pathogenesis of fibrinolysis in liver disease, antithrombin III (AT III) activity, prothrombin fragment (F1 + 2) and d-dimer (D-DI) were measured in 50 patients with liver disease and in 17 healthy controls. Moreover, 4 patients with cirrhosis were randomly assigned to receive either an intravenous infusion of AT III (at two different dosages) or placebo, with a crossover design. Increased levels of D-DI were detected in patients with cirrhosis and hepatocellular carcinoma in comparison both with control subjects and with patients with acute hepatitis or mild chronic liver disease. An inverse correlation was observed between AT III and D-DI (r = -0.755, P < 0.001, simple linear regression), while no correlation was found between D-DI or AT III and F1 + 2. The correlation of the deficiency of AT III activity by infusion of human AT III did not result in any significant change (P0.10, analysis of variance for repeated measures) of the plasma concentration of either D-DI or F1 + 2, in comparison to placebo. Thus, advanced forms of chronic liver disease, but not acute hepatitis and mild forms of chronic liver disease, are associated with increased plasma concentrations of markers of fibrinolysis, which are inversely correlated with AT III activity. However, the correction of the deficient AT III activity does not affect the plasma concentration of either D-DI or F1 + 2, thence not supporting the hypothesis that enhanced fibrinolysis in advanced liver disease is the result of low-grade disseminated intravascular coagulation.

Patients with liver failure can present both thrombotic and hemorrhagic complications because of the deficiency in coagulation factors and inhibitors (protein C and S, antithrombin III) and impairment of fibrinolytic balance. Here we report the case of a 63-year-old man with liver cirrhosis, recurrent thrombosis, and features of low-grade consumption coagulopathy, showing severe antithrombin III deficiency (about 30% of normal values). Treatment with antithrombin III (2000 U/day) and low doses of heparin (5000 U b.i.d.) was successful in modulating the coagulation system toward an antithrombotic effect. After discharge from hospital the ambulatory treatment with antithrombin III concentrates (2000 U twice a week) allowed the attainment of antithrombin III activity of about 60% and prevented the patient from recurrence of venous thrombosis.

Membranous obstruction of the inferior vena cava is a rare disease. The etiology of the membrane is believed to be thrombotic or congenital. In three of 11 siblings from a single family, symptoms of membranous obstruction of the inferior vena cava developed during early adult life. All had signs of more long-standing disease, as judged by the presence of collaterals, cirrhosis and, in one case, hepatocellular carcinoma. On family screening no further cases of membranous obstruction of the inferior vena cava were found. There was also no evidence of inherited defects in the natural coagulation inhibitors (protein C, protein S and antithrombin III) and plasminogen deficiency. This familial occurrence of membranous obstruction of the inferior vena cava supports a congenital etiology, although a thrombotic etiology cannot be totally excluded.

In patients with liver cirrhosis a decrease of the coagulant potential is well-documented and has been linked to the high bleeding tendency among these patients. Whether the decrease of the coagulant potential is only due to a reduced hepatic synthesis of coagulation factors or also to its consumption by disseminated intravascular coagulation is debatable. We investigated hemostasis activation markers thrombin-antithrombin III complexes (TAT), fibrin degradation products (D-Dimer) and plasmin-alpha 2-antiplasmin complexes (PAP) in 41 outpatients with liver cirrhosis (Child-Pugh index 1 n = 18, 2 n = 15, 3 n = 8). Compared to controls similar in terms of age and sex, TAT, D-Dimer and PAP was elevated in the whole group of patients. A progressive increase of D-Dimer and PAP from Child 1 to 3 indicates a relationship between the severity of cirrhosis and the amount of hemostasis activation. Investigation of the natural anticoagulant potential showed significant decreases of antithrombin III (AT III), protein C, and protein S, most pronounced in Child 3 patients. Statistical analysis revealed significant negative correlations between levels of D-Dimer and both AT III and protein C, indicating that hemostasis activation is linked to the loss of anticoagulant potential.

Eighteen patients with an acute thrombosis of the splanchnic veins were reviewed. Most of apparently idiopathic cases of splanchnic vein thrombosis are related to an increased coagulation related to a congenital or acquired defect of haemostasis. The aim of this study was to assess the effects of a new and effective treatment. Nine male and 9 female patients (range of age: 19 to 81 years) experienced a mesenteric venous thrombosis. There were 14 mesenteric vein thromboses with infarction, two transient mesenteric venous ischaemias without bowel infarction and two acute thromboses of the splanchnic veins without bowel ischaemia. A coagulopathy was detected in seven patients: oral contraception, protein C (PC) or antithrombin III (AT III) congenital deficiencies, acquired deficiency of AT III, PC and protein S (PS), polycythaemia in the post-partum period and primary myeloproliferative disorder. No coagulopathy was associated with thrombosis in eight cases: mesenteric haematoma, splenomegaly, cirrhosis, appendicectomy, cholescytectomy, chronic heart failure, treatment with beta-adrenergic receptor antagonist and digitalis, stenosis of the portal anastomosis after liver transplantation. Twelve patients required surgery: eight intestinal bowel resections with immediate anastomosis, four resections without immediate anastomosis. Only one patient underwent a second look for a repeat bowel resection. No death occurred in the early postoperative period and 17 out of 18 patients were alive after 12 years. An oral anticoagulant therapy was undertaken from two months to seven years. However, three patients suffered a recurrent thrombosis. Two of them required a long-term anticoagulation. Six patients experienced a portal hypertension and oral anticoagulants were discontinued in three of them because of bleeding oesophageal varices. Six patients were treated only by unfractionated heparin (UFH) or low molecular weight heparin (LMWH) followed by oral anticoagulants. After laparotomy, two were only treated with UFH without any bowel resection, as mesenteric venous ischaemia was too extensive. These observations suggest that the choice between an appropriate medical or surgical treatment is important and must be discussed. Since 1989, the therapeutic choice has been modified by ultrasonography and contrast enhanced computed tomographic scan which confirms diagnosis, allows to follow up and check the effects of anticoagulation and to choose the time for surgery. When the diagnosis is established and the patient's risk is low, the IU . kg(-1) . d(-1) to obtain an antifactor Xa activity between 0.3 and 0.6 antiXa IU mL(-1).

The coagulation parameters of fourteen patients with advanced liver cirrhosis (3 in Child class B and 11 in class C) were prospectively determined quarterly for one year in order to evaluate the possible relationship between high D-dimer levels and incidence of disseminated intravascular coagulation (DIC) and of gastrointestinal bleeding. The values of D-dimer, fibrin(ogen) degradation products, platelets, fibrinogen, prothrombin activity and antithrombin III were fairly stable in almost all patients and no patient developed an overt DIC; one patient had a significant increase in D-dimer three months after the first control. During the one year follow-up, four patients died, one by the occurrence of hepatocellular carcinoma and three by digestive bleeding. Overall, four patients had upper digestive tract bleeding, three from esophageal varices and one from hemorrhagic gastritis. Hemorrhage was more frequent in patients with high D-dimer levels (3/7, 43%) than in patients with normal D-dimer levels (1/7, 14%). In conclusion, the detection of high D-dimer levels in patients with advanced cirrhosis is not predictive for the occurrence of a overt DIC but seems to be related with an increased risk of gastrointestinal bleeding.
