Patients with severe virus hepatitis and a prothrombin concentration below 25% have a bad prognosis. This is due to direct consequences of hepatic failure and to the rather frequent complications of this disease. The clinical course of such patients is essentially dependent upon the degree of liver regeneration, which again is dependent upon the mass of hepatocytes which are able to regenerate and upon the so called hepatotrophic factors. Patients with severe hepatitis suffer during the first weeks rather frequently from nausea and loss of appetite and for that reason their nutrition is insufficient. In the study recorded here 9 cases were investigated (7 patients with hepatitis B, 2 patients with hepatitis non A non B). The question was asked, if partial parenteral nutrition in addition to a liver diet not containing meat would improve liver function. It could be shown that the prothrombin concentration, which could not be improved by vitamine K1 supplements, was increased during a 7 day parenteral nutrition period from 19,3 +/- 2,9% to 41,5 +/- 8,1% (p less than 0,05), serum albumine and cholinesterase activity improved as well. During the first day of treatment there was a significant fall of ammoniac from 115 +/- 10 mumol to 73 +/- 10 mumol/l (p less than 0,05), at the same time production of urea did not increase. All patients survived. The results show, that parenteral nutrition can improve liver function and decrease the catabolic status of metabolism.

Naturally occurring cases of poisoning of cattle by Cestrum parqui were characterised by ataxia, depression, recumbency, convulsions and death. Three cattle were dosed experimentally by intrarumenal administration of fresh plant material. One calf died 48 h after receiving 30 g (wet weight) of plant/kg bodyweight. Doses of 11 and 17 g/kg caused only mild intoxication, with dullness and anorexia lasting 2 days. In natural and experimental cases the main lesion was hepatic periacinar necrosis. Elevated levels of plasma aspartate transaminase and prolonged prothrombin times were demonstrated in experimental cases. Haemorrhage beneath the serosa and into the intestinal lumen occurred in field cases, but not in the experimental. It is concluded that C. parqui poisoning in cattle is a primary hepatotoxicity.

The prognostic significance of a battery of clinical, laboratory, and histological indicators was assessed in relation to mortality risk in a 1-year study of 253 patients with alcoholic liver disease, of whom 51 died within such time. The relative risk associated with each abnormality was calculated. A number of abnormalities was found to be statistically associated with a higher risk of death. Among the clinical abnormalities, these were: collateral circulation, edema, ascites, encephalopathy, spider nevi, anorexia, and weakness. Among the laboratory tests, these were: albumin, bilirubin, hemoglobin, abnormal prothrombin time, and alkaline phosphatase. Two hundred and sixteen of these patients had liver biopsies in which the quantifiable abnormalities were scored. Among the histological findings, the alterations significantly related to mortality were necrosis, Mallory, and inflammation, while the presence of cirrhosis per se did not influence the mortality risk. The relative risk factors for mortality associated with the histological alterations were lower than those derived from clinical or laboratory measurements. The advantage of using only clinical and laboratory items to derive a global, quantitative expression of severity is discussed. The relative mortality risks provided a means of calculating a "unit of severity" for each clinical and laboratory abnormality. A combined clinical and laboratory index (CCLI) results when these mortality-risk units are added. Such a combined index had a quasi-linear relationship with the risk of mortality for the complete population. This method compared well with severity scores derived from computerized, linear step-wise discriminant function (SDF) analysis and from a logistic regression (LR) analysis. The factors chosen to have independent prognostic significance by the SDF analysis were: encephalopathy, albumin, prothrombin time, and hemoglobin, while only encephalopathy, albumin, and hemoglobin were chosen by the LR analysis. Within a range of values, LR can provide a good discrimination in relation to mortality, similar to that observed for the CCLI in its complete range. However, there are some advantages to the CCLI method vs. the LR or SDF analyses. The CCLI is less susceptible to being unduly influenced by a nonspecific effect of treatment on the items chosen than the SDF and LR analyses, as the CCLI contains a large number of factors. Obtaining a single-severity score such as the CCLI is of value in: (a) assessing the effectiveness of treatment modalities; (b) analyzing the success of randomization; (c) separating cohorts of different severity, and (d) comparing new liver tests, histological abnormalities, or specific biological events with the severity of alcoholic liver disease.

An appropriate animal model of acute fulminant hepatic failure was developed in the guinea pig by he intrabiliary administration of monoethanolamine oleate. The animals were assigned in two experimental groups: 1) ethanolamine group - 42 guinea pigs that received intrabiliary 2,5 ml injection of monoethanolamine oleate; 2) control group - 18 guinea pigs subjected to intrabiliary 2,5 ml administration of saline. The intrabiliary administration of the ethanolamine oleate resulted in massive liver injury with 85,9% of hepatic coma during the first 96 hr. The liver damage was characterized by clinical manifestations (anorexia, increasing stupor, muscle wasting and deep coma), serum biochemical tests (elevations of serum transaminases, bilirubins , alkaline phosphatase), studies of blood coagulation (prothrombin and partial thromboplastin times were markedly prolonged and the concentration of fibrinogen decreased) and histopathological findings (massive hepatic necrosis). This animal model appears promising for future studies of the pathogenesis and treatment of acute hepatic failure.

Sheep given powdered Ferula communis variety brevifolia at dosage of 2.5 g/kg of body weight/d for 15 days developed classical clinical signs of intoxication: anorexia, somnolence, apparent weakness, and hemorrhage. Marked reduction of vitamin K-dependent coagulation factors and prolongation of prothrombin time and activated partial thromboplastin time were consistent with presence of ferulenol, a toxic coumarinic factor in the plant. Changes induced in the coagulation system developed by the second day of plant administration and were normal within 4 days after dosing was stopped. There was no evidence of primary liver damage or platelet malfunction. Of 6 intoxicated sheep, 2 died with only minimal evidence of hemorrhage.

Anorexia, weight loss, fatigue, symptoms of alcohol withdrawal and hepatomegaly are common early presenting signs and symptoms of alcohol abuse. The clinical diagnosis of alcoholic hepatitis can be made in alcoholics with associated fever, leukocytosis, jaundice and tender hepatomegaly. Associated laboratory abnormalities may include leukocytosis or leukopenia, anemia, a prolonged prothrombin time and elevated liver enzymes, including aspartate amino-transferase (AST), alanine aminotransferase (ALT), alkaline phosphatase and bilirubin. An AST-to-ALT ratio greater than 2 is common in patients with alcoholic hepatitis. Liver biopsy may be required to establish the diagnosis and to identify other pathology, such as cirrhosis. Histologic diagnosis of alcoholic hepatitis requires the presence of liver cell damage, an inflammatory infiltrate and fibrosis. Biopsy-proven cirrhosis with alcoholic hepatitis or a significantly elevated total bilirubin level and prolonged prothrombin time are associated with a worse prognosis. Abstinence from alcohol, nutritional supplementation and corticosteroids are the mainstays of treatment for severe alcoholic hepatitis.

Woodchucks were used to study the antiviral activity and toxicity of fialuridine (FIAU; 1,-2'deoxy-2'fluoro-1-beta-D-arabinofuranosyl-5-iodo-uracil). In an initial experiment, groups of six chronic woodchuck hepatitis virus (WHV) carrier woodchucks received daily doses of FIAU by intraperitoneal injection for 4 weeks. At 0.3 mg/kg/d, the antiviral effect was equivocal, but at 1.5 mg/kg/d, FIAU had significant antiviral activity. No evidence of drug toxicity was observed during the 4-week period of treatment or during posttreatment follow-up. In a second experiment, groups of nine WHV carriers or uninfected woodchucks were given 1.5 mg/kg/d of FIAU orally for 12 weeks, and the results compared with placebo-treated controls. After 4 weeks, the serum WHV-DNA concentration in the FIAU-treated carrier group was two to three logs lower than that in the placebo-treated group. After 12 weeks of FIAU treatment, serum WHV DNA was not detectable by conventional dot-blot analysis, hepatic WHV-DNA replicative intermediates (RI) had decreased 100-fold, and hepatic expression of WHV core antigen was remarkably decreased. No evidence of toxicity was observed after 4 weeks, but, after 6 to 7 weeks, food intake decreased and, after 8 weeks, the mean body weights of woodchucks treated with FIAU were significantly lower than controls. Anorexia, weight loss, muscle wasting, and lethargy became progressively severe, and all FIAU-treated woodchucks died or were euthanized 78 to 111 days after treatment began. Hepatic insufficiency (hyperbilirubinemia, decreased serum fibrinogen, elevated prothrombin time), lactic acidosis, and hepatic steatosis were characteristic findings in the final stages of FIAU toxicity in woodchucks. The syndrome of delayed toxicity in woodchucks was similar to that observed previously in humans treated with FIAU, suggesting that the woodchuck should be valuable in future investigations of the molecular mechanisms of FIAU toxicity in vivo and for preclinical toxicological evaluation of other nucleoside analogs before use in patients.

A review of 60 cases of immune-mediated hemolytic anemia (IMHA) in the dog was performed in order to characterize the disease and to identify potential prognostic indicators. Dogs ranged in age from 1 to 13 years, with a mean age of 6.5 years. The 2 most commonly affected breeds were Cocker Spaniels and Labrador Retrievers. Fifty-two of the 60 dogs tested (87%) were autoagglutination positive and spherocytes were present in 45 (75%). Forty-one (89%) of 46 patients tested positive for the presence of immunoglobulin on the red blood cell surface (Coombs assay). The most common clinical signs at presentation were lethargy, weakness, pale mucous membranes, icterus, hemoglobinuria, and anorexia. PCV less than 25% was present in 59 (98%) dogs. At the time of presentation, 35 dogs (58%) had a nonregenerative anemia, whereas 25 patients (42%) had a regenerative response. Thrombocytopenia was seen in 41 (68%) dogs. Nine of 34 dogs (26%) had a prolonged prothrombin time, 19 of 34 (56%) had a prolonged activated partial thromboplastin clotting time, and 12 of 34 (35%) had abnormal fibrinogen concentrations. All dogs received prednisone at immunosuppressive doses (2.2-4.4 mg/kg PO as a single or divided dose every 24 hours) and cyclophosphamide as primary therapy. Forty-one dogs (63%) received cyclophosphamide at 50 mg/m2 q24h for 4 days, whereas 9 dogs (15%) received an initial high dose (200 mg/m2) followed by 3 days of a lower dose (50 mg/m2 q24h). No statistical difference in survival times was found for either protocol. Thirteen dogs were treated with azathioprine in addition to cyclophosphamide and prednisone. The median survival time of dogs that received all 3 drugs was 370 days as compared to 9 days for those dogs that were treated with cyclophosphamide and prednisone alone. Thirty-one (52%) dogs died from the disease, 13 (22%) dogs were alive, and 15 (25%) dogs were lost to follow-up. The median length of survival for all dogs was 21 days. Eight dogs that were discharged from the hospital suffered a relapse (PCV < 25%).

Prognosis and outcome of patients with pancreatic carcinoma is poor. The aim of the study was to investigate (1) which factors of medical history and clinical status as well as which laboratory parameters determine survival in pancreatic carcinoma and (2) whether specific data can be used as prognostic parameters or for early diagnosis of pancreatic carcinoma. In total, 287 patients with pancreatic carcinoma were enrolled in the study. In 193 subjects, only palliative treatment was possible. Survival was assessed using univariate survival probability curves by Kaplan-Meier. Comparison of patient groups with regard to survival was achieved using the log-rank test. Multivariate analysis was carried out using the Cox regression model. Overall, 22 factors, showing a significant impact on survival in pancreatic carcinoma were found, e.g., tumor-associated factors such as (1) tumor stage according to the UICC classification including TNM-based staging, grading, tumor site, and vascular infiltration; (2) preoperative habits and signs and symptoms (physical condition, pain, loss of appetite, ethanol consumption); (3) change of laboratory parameters (CA 19-9, bilirubin, prothrombin time, urea, C-reactive protein), and (4) type of intervention (surgical approach, R0/1/2 resection). Using multivariate analysis, seven factors (UICC tumor stage and site, surgical intervention including number of resected lymph nodes, chemotherapy, occurence of a carcinoma in relatives, preoperative physical condition, night sweat) were determined. In the 193 patients with palliative treatment, only ten factors (among them UICC tumor stage including the presence of metastases; data from the medical history such as physical condition, loss of appetite, and carcinoma in relatives, and laboratory parameters including prothrombin time, protein content, and aspartate aminotransferase levels) were found to be important. Chemotherapy had the strongest impact on survival which was confirmed by multivariate analysis, followed by tumor stage (UICC) and preoperative appetite. Besides tumor-associated determinants, data from the medical history, and pathological laboratory parameters, the prognosis in pancreatic carcinoma is considerably determined by the treatment such as interventional and/or using antineoplastic agents.

A 41-year-old man developed severe hepatic dysfunction following a 3.5-week course of terbinafine (250 mg/day). He suffered marked pruritus, jaundice, malaise, anorexia and loin pain. Serum bilirubin rose to a peak value of 718 micromol/l with alkaline phosphatase at 569 U/l, alanine aminotransferase at 90 U/l, aspartate aminotransferase at 63 U/l and a prolonged prothrombin time of 21 s, unresponsive to vitamin K. Transjugular liver biopsy showed canalicular cholestasis consistent with a drug reaction. Symptoms resolved 11 months after drug cessation, with liver function tests returning to normal values after 15 months. This case represents the most severe cholestatic reaction reported to date, resulting in patient recovery without liver transplantation. A comprehensive literature review is provided.
