The objective of this study was to characterize the hemostatic defect in dogs with infectious canine hepatitis (ICH), a naturally occurring viral disease of dogs. Five littermate dogs were inoculated with 10(3) TCID50 of ICH virus intravenously. Two littermates were controls. The clinicopathologic manifestations of ICH were fever, depression, anorexia, hematemesis, melena, widespread mucocutaneous petechiae, prolonged bleeding from venipunctures, faceial edema, leukopenia, and proteinuria. The hemostatic defect of ICH was characterized by thrombocytopenia, abnormal platelet function, prolonged one-stage prothrombin time and activated partial thromboplastin time, normal thrombin times, depressed factor VIII activity, and increased fibrin-fibrinogen degradation products. These findings suggested that the central pathologic mechanism of the abnormal hemostasis in ICH was disseminated intravascular coagulation (DIC). ICH is an example of DIC induced by viral infection. This disease is a suitable model for investigation of the detection, pathogenesis, and therapy of DIC.

On the basis of an analysis of 256 patients with diffuse peritonitis, destructive pancreatitis, mechanical jaundice and purulent cholangitis and complex investigations it was established that the degree of clinical manifestations of endointoxication corresponded to a definite degree of disorders of the central nervous system. The most adequate indices of the course and prognosing the toxic process are thought to be the level of the leukocytic index of intoxication, the prothrombin index, the degree of monocytopenia and proteinuria. Their dynamics reflects changes of the concentration of toxic intermediary metabolites and main characteristics of electron paramagnetic resonance of blood plasma.

Carbetimer (carboxyimamidate) was administered at a dose of 6,500 mg/m2/day intravenously for 5 consecutive days to 14 patients with measurable metastatic or recurrent colorectal cancer in a single institution phase II study of the Northern California Oncology Group. A total of 38 cycles of therapy were administered; nine patients completed at least three cycles of treatment. No partial or complete responses were observed. One patient did have a greater than 50% response in the liver while developing new retroperitoneal lymphadenopathy and is considered a nonresponder. Carbetimer was well tolerated with elevations of calcium from 10.2 to 12.5 mg/dl in nine patients, prolongation of prothrombin time and partial thromboplastin time in 14 patients, proteinuria in 10 patients, dizziness in six patients, nausea in two patients, and venous pain during infusion in three patients. Myelosuppression was not observed. Carbetimer at this dose and schedule is inactive in the treatment of colorectal cancer.

We measured the plasma concentrations of the natural anticoagulant protein C and its cofactor protein S in 17 patients with severe proteinuria. In addition, prothrombin and antithrombin III levels were measured in the same group of patients. These results were compared with results obtained in 26 healthy controls and a group of 14 patients with chronic renal insufficiency (CRI) but minimal proteinuria. Protein C, protein S, and prothrombin levels were not significantly different between healthy controls and patients with CRI. However, protein C, protein S, and prothrombin levels were significantly elevated in 71%, 82%, and 76%, respectively, of patients with proteinuria. Antithrombin III levels were decreased in three of these 17 patients with proteinuria. Plasma concentrations of protein C, protein S, and prothrombin correlated significantly with each other and were inversely correlated with serum albumin concentrations. In three patients, high protein C, protein S, and prothrombin levels returned to normal during remission of the proteinuric state. Proteins C and S were not detectable in the urine of two patients with high-grade proteinuria. Thus, the plasma levels of the vitamin K-dependent, natural anticoagulant protein C and its cofactor protein S are increased in patients with proteinuria. The elevated plasma levels of other vitamin K-dependent proteins, such as prothrombin, suggest a generalized elevation in vitamin K-dependent protein synthesis in patients with proteinuria.

Recently Brewer et al. reported the possibility of an oral zinc therapy in Wilson's Disease. We treated a 19 years old patient with decompensated liver cirrhosis due to Wilson's disease with zinc-sulphate. D-Penicillamine had to be withdrawn since proteinuria occurred under treatment. After the discontinuation of D-Penicillamine an increase of serum copper almost up to normal range was observed; concomitantly urinary copper elimination decreased. Under oral zinc sulphate therapy (145 mg/day) a drop of serum copper level was achieved and liver function improved: serum albumin, gamma globulins and prothrombin time reached normal values. The patient did not complain any side effects during oral zinc sulphate therapy. Oral zinc therapy in Wilson's Disease may be regarded as an alternative to D-Penicillamine treatment when this drug has to be discontinued because of side effects.

Heymann nephritis was induced in rats with spontaneous hypertension (group HN), and renal lesions were investigated at the twentieth and thirty-sixth week. An identical group given antihypertensive drugs (group HN-AH), an identical group given anticoagulant drugs (group HN-AC), and a nonimmunized control group of spontaneously hypertensive rats (controls) were also examined. Massive proteinuria, hypoalbuminemia, and hyperlipidemia were present in groups with induced Heymann nephritis (HN, HN-AH, and HN-AC). Coagulation studies demonstrated a shortening of prothrombin time, an increase in serum fibrinogen and thrombocytes, and a reduction of antithrombin III in the groups HN and HN-AH. Necrotizing lesions were observed only in group HN and without further elevation in blood pressure. Intravascular thrombosis was prominent at the twentieth week, and marked fibrinoid necrosis appeared at the thirty-sixth week. These vascular lesions were not observed in the HN-AH, HN-AC, and control groups. Thus, a state of hypercoagulability in addition to high blood pressure probably contributes to the genesis of necrotizing vascular lesions in spontaneously hypertensive rats with nephritis.

Factor XII clotting activities and antigen levels were assayed in 14 plasma samples from 10 patients with nephrotic syndrome; the group was heterogeneous clinically and histologically. Factor XII was low at initial sampling in 7 of the 10 patients; in 7 of the 14 samples, factor XII antigen was in excess over clotting activity. Inhibition of factor XII could not be demonstrated; excess plasma antigen and urinary antigen (when present) had normal patterns on crossed-immunoelectrophoresis, indicating no major changes in charge or size. In 3 patients tested more than once, plasma levels of factor XII were increased up to 6fold in steroid-induced remission. Of other hemostatic factors assessed for comparison, factor VIII was elevated in 11 of the 14 samples; eight of these had elevated factor VII levels as well. Eight samples from six patients showed low antithrombin III levels; one of these patients had recurrent thromboses. Antithrombin III levels correlated with the serum albumin concentration. Only two of the eight urines tested had detectable factor XII antigen; a third had factor IX and prothrombin and no factor XII. Plasminogen and antithrombin III were readily demonstrated in all urine samples with higher concentrations in those patients with less selective proteinuria. Urinary and plasma levels were not correlated, suggesting that increased consumption or turnover was not simply related to increased filtration.

The concentrations of 23 plasma proteins were measured by radial immunodiffusion in the plasma and ascites of 17 patients with cirrhosis and four patients with intraperitoneal malignancies, to learn whether there is a selectivity in the movement of proteins from plasma into ascites, analogous to that of proteinuria. Additionally, since some of the proteins are involved in coagulation, we hoped to clarify the coagulopathy frequently seen following peritoneovenous shunting of ascites. Analysis was by groups: group 1 consisted of nine patients with cirrhosis with an ascites-total protein content less than 2.5 g/dl; group 2 consisted of eight patients with cirrhosis with ascites-total protein content greater than or equal to 2.5 g/dl; and group 3 consisted of four patients with malignant ascites. The ratio of the plasma concentration/ascites concentration ([P]/[A]) for each protein was calculated for each patient. In each group the median [P]/[A] for each protein was plotted against the natural logarithm of its molecular weight (In MW). For 21 of the 23 proteins, [P]/[A] showed a close linear relationship to In MW. Fibrogen and plasminogen showed significant (p < 0.0002) elevation above the regression line relating [P]/[A] to In MW. This indicates depletion of fibrinogen and plasminogen in ascites. The ascites in group 1 showed moderate selectivity, defined as the slope of the regression line (1.59), while groups 2 and 3 were essentialy nonselective (0.35 and 0.50). Fibrin-split products were elevated in all ascites but not in plasma, indicating either fibrinolysis or fibrinogenolysis within the ascites. A normal ratio for prothrombin suggests fibrinogenolysis may be the dominant mechanism. Thus the coagulopathy induced by LeVeen valve insertion may be in part secondary to the infusion of plasmin or a plasminogen activator into the circulation.

Acute fatty liver of pregnancy is a rare clinical entity unique to pregnancy that can lead to hepatic failure and encephalopathy and, if the diagnosis is delayed, to death for the baby and the mother. The characteristic histological picture demonstrates microvesicular fatty infiltration of hepatocytes. Acute fatty liver of pregnancy is a disease of the third trimester of pregnancy. The most significant clinical findings are nausea or vomiting, abdominal pain, jaundice, hepatic encephalopathy, increased transaminase levels, decreased platelet count, increased prothrombin time, and renal failure. Hypertension and proteinuria are common. Liver biopsy is not always necessary for diagnosis but may be useful in atypical cases. The primary therapy is early delivery and supportive care. Both the obstetric team and the medical consultants must have a high index of suspicion for this disease because early delivery is lifesaving and has transformed the prognosis for the mother and the baby. Collaboration between obstetricians and gastroenterologists is necessary to make the diagnosis and also to improve our understanding of this disease of unknown etiology.
