A 48-year-old woman with type II diabetes developed fatigue, arthralgia and myalgia. A few weeks later she was found to have hepatomegaly. The erythrocyte sedimentation rate was raised (53/93 mm), as were liver enzyme activities (GOT 186 U/l; GPT 240 U/l; gamma-GT 199 U/l), the gamma-globulin levels (40.7%;IgG 4470 mg/dl, IgA 698 mg/dl, IgM 245 mg/dl), antinuclear antibodies and antibodies against double-strand DNA, smooth muscles and actin. Laparoscopy revealed small-nodular liver cirrhosis. The autoimmune hepatitis was treated with prednisolone (initially 60 mg daily, then reduced to 10 mg daily) and azathioprine (initially 100 mg daily, reduced to 50 mg daily). The symptoms markedly improved. But one year later, during follow-up examination, gastric polyps were found, excised and histologically found to be carcinoid. The gastrin level was raised to 765 pg/ml. Another year later the liver cirrhosis had advanced further and the type A gastritis was still present, but there was no sign of carcinoid recurrence.

A reduction in serum enzymes has been already observed by administering ursodeoxycholic acid to patients with chronic active hepatitis. The aim of this study was to assess whether the liver histological activity of inflammation was modified by a 12-month treatment with ursodeoxycholic acid. Thirty-six patients with chronic active hepatitis, fulfilling the inclusion criteria, were admitted to the trial. Patients were randomly allocated to receive double blind either 600 mg/day of ursodeoxycholic acid (Group A: 18 patients) or placebo (Group B: 18 patients). Clinical and biochemical follow-up was performed at acid (Group A: 18 patients) or placebo (Group B: 18 patients). Clinical and biochemical follow-up was performed at 3-month intervals. A percutaneous liver biopsy was performed before and after 1 year of treatment. Histological hepatitis activity was assessed using Knodell's numerical scoring system, while biliary damage was evaluated by an appropriate scoring system. Sixteen and 12 patients in Groups A and B, respectively, completed the clinical and biochemical follow-up. Although a reduction in serum enzymes was found in both groups, multifactorial covariance analysis showed that the reductions in alanine aminotransferase, aspartate aminotransferase and gamma glutamyl transpeptidase were significantly higher in Group A than in Group B. Biochemical remission was not observed in either group. Histological analysis showed a dichotomy between the results from the hepatitis and the biliary components of the disease process. No differences were found in the two groups before or after treatment in histological activity index, which measures the "hepatitic" component. Nor were there any significant differences in baseline values.(ABSTRACT TRUNCATED AT 250 WORDS)

Following a three-week administration of alpha-interferon (IFN-alpha), a 62-year-old woman with chronic hepatitis C manifested fever and dyspnea and showed diffuse infiltrative opacities on chest roentgenograms. Her laboratory data included results of anemia with reticulocytosis, a decreased complement level and hepatitis with elevated ALP, LDH and gamma-GTP. Because laboratory data also revealed a positive lymphocyte stimulation test for IFN-alpha, this cytokine was considered to be responsible for the development of interstitial pneumonia, hemolytic anemia and cholestatic liver dysfunction due to its immunomodulatory effects. Although these three disorders have been reported to develop singly after IFN-alpha therapy, this is the first report of a patient in whom these disorders occurred simultaneously.

HBsAg-positive patients with end-stage renal failure have a high prevalence of asymptomatic chronic hepatitis. In order to determine the usefulness of hepatic cytology in the diagnosis of liver disease, the findings of hepatic needle core biopsy (NCB) and fine needle aspirative biopsy (FNAB) were compared in 15 HBsAg-positive uremic patients. The patients, aged 42 +/- 12 years, 14 males, were on hemodialysis for periods ranging from 13 to 105 months. The NCB was processed by standard histologic and immunohistochemical techniques and FNAB by the conventional technique, using the total corrected increment score (TCI). Plasma samples were collected for evaluation of hepatic function and for viral serologic tests. In 15 patients a diagnosis was made by NCB: normal, 7 cases; chronic persistent hepatitis, 4 cases; and chronic active hepatitis, 4 cases. When the patients were allocated into two groups according to the severity of the liver histologic findings [group I--minor changes (normal+chronic persistent hepatitis), 11 patients; group II--major changes (chronic active hepatitis), 4 patients], statistically higher values were found in the major changes group for alanine aminotransferase (49 +/- 33 vs. 24 +/- 11, p = 0.04), gamma-glutamyl transpeptidase [148 +/- 53 vs. 38 +/- 28, p < (minor) 0.02] and TCI (3.7 +/- 1.2 vs. 2.5 +/- 0.8, p = 0.04). In conclusion, liver FNAB can be useful as a screening procedure for the identification of liver histologic changes (minor or major) in uremic HBsAG-positive patients.

A 69-year-old Japanese female was admitted because of general fatigue. Laboratory data showed elevation of serum total bilirubin, transaminase, gamma-glutamyl transpeptidase, and creatinine levels. An immunological study revealed hypergammaglobulinemia, low titer of complement, and high titers of antinuclear antibody, anti-DNA antibody, and circulating immune complexes. Antibodies to parainfluenza virus 3 were positive. Histology of the liver disclosed numerous giant cell hepatocyte transformations with the lobular architecture being slightly distorted by portal inflammation and fibrosis. These findings led us to make a diagnosis of giant cell hepatitis associated with systemic lupus erythematosus. Prednisolone was effective in improving the anemia and the serum immunoglobulin, immune complex, and antinuclear antibody levels. The addition of cyclosporine to the initial corticosteroid therapy was also beneficial in decreasing the transaminase level and in improving liver histology. The patient died of acute pneumonitis and renal failure on the 166th day after admission. Parainfluenza virus 3 and autoimmune mechanisms were thus considered to be the causes of the giant cell hepatitis.

In early hepatic fibrosis, increased amounts of type III collagen are deposited. Persistently high serum concentrations of aminoterminal type III procollagen propeptide (PIIIP) correlate with the activity of the fibrogenic process. Another index for the detection of fibrosis, the PGA index, combines the prothrombin time, gamma-glutamyl transpeptidase activity, and serum apolipoprotein A1 concentration (the latter falls with progressive fibrosis). We compared PIIIP measurements and PGA index in patients with various histological forms of alcoholic liver disease (104), primary biliary cirrhosis (38), and chronic B virus hepatitis (27), and in healthy age-matched controls (30). The ability of each test to identify correctly patients with fibrosis or cirrhosis was assessed with receiver operating curves. The PGA index was much higher in all groups of patients with alcoholic liver disease than in controls (p < 0.0001). PIIIP concentrations were also substantially higher than in controls (p < 0.05 for fatty liver, p < 0.0001 for all other groups), especially in the group with alcoholic hepatitis and cirrhosis. For the detection of cirrhosis the PGA was 91% sensitive and 81% specific and the PIIIP concentration was 94% sensitive and 81% specific. The two tests combined had 85% sensitivity, but 93% specificity. Among patients with primary biliary cirrhosis, both PGA index and PIIIP concentration correlated well with the severity of the disease, determined by the Mayo score (r = 0.72 and 0.66 respectively). The combined tests were 96% sensitive for the detection of fibrosis. All patients with chronic B virus hepatitis had raised PGA and PIIIP values in comparison with controls (p < 0.0001) but there were no differences between subgroups. Substantially raised PIIIP concentrations thus identify the subgroup of alcoholic patients with both hepatitis and cirrhosis. The combination of PGA index and PIIIP concentration may be useful for targeting treatment with antifibrotic drugs and to reduce the need for liver biopsy.

The use of cadaveric organ donors with positive serologic tests for hepatitis C (HCV) has caused considerable debate. We have reviewed the clinical course of 43 EIA1 HCV-negative recipients who received kidney transplants from EIA1 HCV-positive donors (Study). We have attempted to define the rate of HCV-RNA transmission and to determine the frequency of HCV disease transmission as determined by abnormalities in liver function tests. Viral transmission was assessed using serologic assays for HCV antibody formation (EIA1, EIA2, and Matrix--an automated multiple antigen immunoblot assay) and with PCR testing for the presence of HCV-RNA on recipient sera. Liver function was followed longitudinally in the Study patients and compared with a group of 103 kidney recipients of organs from EIA1 HCV-negative donors (Control). Of the Study patients, 56% became PCR-positive for HCV-RNA, suggesting the transmission of HCV-RNA from the HCV-positive donor. Interpretation of serologic tests for HCV was complex. Currently available first (EIA1) and second (EIA2) generation serologic assays were always negative. The multiple antigen immunoblots assay (Matrix) had a high positive predictive value (93%) for the presence of HCV-RNA transmission, but one-third of Matrix-negative Study patients were PCR-positive (sensitivity = 66%). Currently, only 38% of recipients have HCV-RNA, suggesting that the virus may have been cleared by one-third of Study recipients who had circulating virus. Traditional tests of liver function (ALT, AST, AP, and GGT) were of limited use in predicting HCV-RNA transmission. Average AST, AP, and GGT were similar in the two groups. Average ALT was increased (93 I/U and 47 I/U) in Study and Control patients, respectively, but this difference was not significant. Episodes of abnormal liver function (ALT 60-99 IU for > or = 14 days) occurred in 22% of Study and 10% of Control patients (P = NS) and lasted longer in Study compared with Control patients (301 vs. 138 days; P < 0.02). Hepatitis (ALT > or = 100 IU for > 14 days) occurred with an equal frequency (6.5%) in both groups. The presence of HCV-RNA did not predict episodes of abnormal liver function. Fulminant hepatitis or rapidly progressive cirrhosis did not occur in the recipients of organs from HCV-positive donors. These data demonstrate a high efficiency of transfer of HCV-RNA by kidney transplantation from an HCV-positive donor to an HCV-negative recipient. A majority of the patients have asymptomatic HCV infection.(ABSTRACT TRUNCATED AT 400 WORDS)

Flow cytometric analysis of the ploidy of normal and neoplastic hepatocyte nuclei obtained from adult woodchucks, a model of human hepadnavirus-induced hepatocellular carcinoma, was performed. All 36 samples of nuclei from non-neoplastic liver from woodchuck hepatitis virus-infected or uninfected liver were diploid, indicating that age-related nuclear polyploidization does not occur in this species, unlike other rodents. Individual or multiple hepatic neoplasms were obtained from each of 14 woodchuck hepatitis virus-infected woodchucks. Nineteen samples of hepatocellular carcinoma and eight adenomas were examined. Aneuploid nuclei were detected in 10 of the hepatocellular carcinomas and three of the adenoma samples. Similar DNA indexes, ranging from 1.11 to 1.22, were found in 7 of the 10 aneuploid HCCs and all 3 aneuploid adenomas. Nine of the 19 hepatocellular carcinoma samples and 5 of the 8 adenomas were diploid. Four of the diploid hepatocellular carcinomas had increased proportions of tetraploid nuclei. The presence of aneuploid nuclei was not related to histological appearance of the neoplasms or serum gamma-glutamyltranspeptidase levels. Because none of the hepatocellular carcinomas metastasized, the presence of aneuploidy could not be related to biological behavior. We determined the proportion of uninucleate and binucleate hepatocytes in hepatocellular carcinoma and nonneoplastic liver. Approximately 7% of hepatocytes were binucleate in nonneoplastic liver from woodchuck hepatitis virus-infected and uninfected liver. Only 2% of malignant hepatocytes were binucleate. The results of this study indicate that aneuploidy is a common change in hepatic neoplasms from woodchuck hepatitis virus-infected woodchucks.

We report on 56 children with sclerosing cholangitis (SC) seen between 1972 and 1992. The first symptoms occurred at a mean age of 3.7 years; 15 infants had neonatal cholestatic jaundice. At diagnosis, cholestatic jaundice was present in 25 children, hepatomegaly in 54, splenomegaly in 41, and ascites in 12. Serum alkaline phosphatase activity was increased in 49 patients and gamma-glutamyltransferase activity in all patients tested. Most often the histopathologic findings were extensive portal fibrosis and neoductular proliferation. Cholangiography showed abnormal intrahepatic bile ducts in all children and abnormal extrahepatic bile ducts in 35 (63%). The children were separated into three groups: (1) those with SC of neonatal onset (27%); (2) those with SC of postneonatal onset associated with another disease (55%)--histiocytosis X in 14 children, immunodeficiency syndromes in 8, chronic inflammatory bowel disease or autoimmune hepatitis in 8, and congenital psoriasis in 1; and (3) those with SC of postneonatal onset without an associated disease (18%). Biliary cirrhosis was present in all but three children after 6 months to 19.3 years of follow-up. Eleven children died of portal hypertension or liver failure, and six died of a complication related to the associated disease. Fifteen children had liver transplantation; 11 of these are alive 6 months to 6 1/2 years later without recurrence of SC. The overall estimated median survival time of children with SC was 10 years from clinical onset. These results indicate that SC should be suspected in all children with a chronic cholestatic disease and increased serum gamma-glutamyl transferase activity, especially when diseases known to be associated with SC are present. The prognosis is poor, but liver transplantation should be considered except in those with severe immunodeficiency syndromes.

To evaluate the clinical applications of serum thymidine kinase (TK) activity, we compared the results obtained with this parameter with those of other liver function tests in 27 patients with acute viral hepatitis and 16 normal controls. In those in the acute stage, the serum TK activity increased significantly to 55.5 +/- 66.5 U/L. There was no significant correlation between serum TK activity and findings for serum albumin, bilirubin, alkaline phosphatase or r-glutamyl transpeptidase. However, it did correlate significantly well with the serum activity of aspartate aminotransferase (AST) (r = 0.621, P < 0.01), alanine aminotransferase (ALT) (r = 0.551, P < 0.01), and lactate dehydrogenase (LDH) (r = 0.620, P < 0.01). Serum TK activity reached higher than 70 U/L in 8 of 11 patients with hepatitis A; however, no patients with the other types of hepatitis reached such a high level. During the recovery stage, the serum TK activity decreased significantly to 5.9 +/- 1.7 U/L (P < 0.01), and did not correlate with AST, ALT, LDH or other conventional liver function parameters. The data suggest that an elevation of serum TK in patients with acute viral hepatitis results from hepatocellular damage. A marked elevation of serum TK activity may thus provide a marker for acute hepatitis A infection.
