Necropsy findings of hepatobiliary system from 78 patients with end-stage renal disease maintained on hemodialysis are reported. Ninety percent of the patients exhibited some abnormalities. Multiple abnormalities often coexisted in each patient. Hepatomegaly was found in 50% of the patients and could be attributed to a discernible cause in all but two of the affected patients who had isolated hepatomegaly. Hepatic congestion was also prevalent and was complicated by fibrosis, cardiac cirrhosis, and centrilobular necrosis and hemorrhage in some patients. This was associated with chronic fluid overload, hypertension, and/or cardiovascular disease in the affected patients indicating the importance of adequate control of these factors. Mild periportal hepatic fibrosis, fatty metamorphosis, triaditis, hemosiderosis, and cystic changes were also seen with some frequency--the latter were associated with polycystic kidney disease and were complicated by massive intracystic hemorrhage and abscess formation, each in one patient. Chronic active hepatitis was found in three patients and was associated with chronic HBs antigenemia in one patient and presumed non-A, non-B infection in two. Nearly 22% of the patients showed either cholelithiasis at autopsy or before cholecystectomy due to complications. Significant negative findings included lack of acute viral hepatitis, silicone hepatosis, and recently described focal anoxic lesions associated with erythrocyte sludging. In conclusion, the present study has demonstrated the spectrum of hepatobiliary pathology in a large group of patients with end-stage renal disease maintained on hemodialysis.

To assess the spectrum of hepatic abnormalities in acquired immune deficiency syndrome (AIDS), we reviewed clinical, biochemical, and pathological material in 32 patients with AIDS. Eight-four percent of AIDS cases had a history of intravenous drug abuse. Ninety percent of AIDS patients has some liver biochemical abnormality at the first presentation of illness. During the course of AIDS, significant (p less than 0.05, paired Student's t test) rises in alkaline phosphatase and bilirubin occurred, without rises in aminotransferases. Mean abnormalities were mild, reflecting approximately 2-fold increases over baseline. Liver failure was not believed to contribute to the death of any AIDS patient. Pathological findings in AIDS included specific infectious diagnosis in 26%, granulomas in 16%, hemosiderosis in 26%, nonspecific abnormalities in 39%, cirrhosis in 23%, and chronic active hepatitis in 3%. AIDS cases were also compared to 10 selected age, sex, and epidemiologically similar non-AIDS patients. Although granulomas or infections were not seen in our comparison group, only the incidence of chronic active hepatitis was significantly different between the groups. If only those with intravenous drug abuse were studied, then none of 24 AIDS patients versus four of eight non-AIDS cases (p less than 0.005) had chronic active hepatitis. AIDS patients with specific hepatic infections tended to have a higher alkaline phosphatase and aspartate aminotransferase (p less than 0.05) than noninfected cases. However, substantial overlap existed, and no difference in hepatomegaly was noted. Ninety percent of AIDS patients were ingesting at least one potentially hepatotoxic drug. We conclude that AIDS patients have a high incidence of underlying hepatic abnormalities. However, clinical and biochemical abnormalities are similar in our selected liver biopsy patients with intravenous drug abuse with or without AIDS. As expected, AIDS patients have a higher incidence of hepatic granulomas and infections, but these patients were not clearly distinguishable from other AIDS cases. Histological examination showed a wide array of changes by light microscopy, but no specific lesion of AIDS was noted. The low incidence of chronic active hepatitis in this AIDS population may imply that the altered T lymphocyte function in AIDS could influence the course of liver disease in these patients.

One hundred and twenty-five children with chronic liver disease were seen in Pune in 13 months. Fifty-nine of them, aged 8-39 months, had Indian childhood cirrhosis histologically diagnosed. Their characteristics included an insidious onset of symptoms, a geographical clustering of cases in rural areas north-east of Pune, a high rate of parental consanguinity and affected siblings, and a very high hepatic copper concentration (790-6654 micrograms/g dry weight). Only 8 survived for 6 months, adverse prognostic features being jaundice, ascites, enlargement of the gall bladder, and severe anaemia at presentation. Clinical differentiation from other liver disorders in the same age group was clear in advanced cases but unreliable in earlier cases. Four asymptomatic siblings with hepatomegaly had a benign course. The need for non-invasive methods to diagnose early cases in the community is demonstrated. The other major diagnostic categories were: unresolved hepatitis (12); chronic active hepatitis (7); cryptogenic cirrhosis (6); neonatal hepatitis and biliary atresia (8).

The results of clinical, biochemical and histological studies in 26 children with chronic hepatitis B are reported. Most cases were detected when diagnostic procedures were arranged because of non specific abdominal complaints, by routing tests after acute hepatitis or multiple transfusions, and by examination of family members. Hepatomegaly was found in half of the cases, splenomegaly in a quarter. Other clinical signs were rarely seen. Among the biochemical findings, elevated serum transaminase activities were the most reliable indicators of chronic hepatitis. There was a significant difference of the mean transaminase activities between patients with CPH and CAH. In 15 children CPH was diagnosed histologically. 9 children had CAH, 2 children showed signs of MinH.

We determined the course of hepatitis C infection in 125 patients with a history of injection drug use. The mean age at presentation was 43.5 years, and the mean age of initiating injection drug use was 23.1 years. Fatigue and hepatomegaly were present in as many as 60% of patients. All had antibodies to the hepatitis C recombinant protein C25, and 99% were positive for hepatitis C virus RNA. After the initial workup, 33 (26%) patients had chronic hepatitis, 46 (37%) had chronic active hepatitis, 45 (36%) had cirrhosis, and 1 (0.8%) presented hepatocellular carcinoma. During follow-up, hepatocellular carcinoma developed in 2 other patients. In 74 patients with a 1-year history of injection drug use, the mean number of years to the development of chronic hepatitis, chronic active hepatitis, cirrhosis, and hepatocellular carcinoma were 15.6, 17.6, 19.4, and 26.3 years, respectively. In this subgroup of patients, heavy alcohol abuse did not appear to influence the progression of liver disease. The 2-year case-fatality rate was 2%. Our findings indicate that hepatitis C is a progressive disease, but only a few died during the average 20.4 years after the initiation of injection drug use. Antiviral treatment to eradicate the virus and halt the progression of disease is indicated in this group of patients.

Use of long-term total parenteral nutrition (TPN) is often presumed to be associated with serious hepatic dysfunction. In this retrospective study, we reviewed the complete charts of patients who had received TPN for more than 2.5 years, starting in infancy or childhood, for evidence of liver dysfunction. There were 16 male and 10 female patients with a total of 254.5 patient years on TPN. Seventeen patients have been on TPN since birth or early infancy. Thirteen of 26 patients derive > or = 90% of their calorie intake from TPN. Six patients had hepatomegaly; two of them also had splenomegaly. Twenty-one patients had normal transaminases, nine have had past episodes of raised enzymes ranging from 2.5 to 7.5 times normal. Seventeen patients always had normal bilirubin levels, five had past episodes of hyperbilirubinaemia, while four patients had persistently raised bilirubin levels (range 1.5-20.7 g/dl). Alkaline phosphatase was normal for age in all patients except two. Hepatic synthetic function, as measured by albumin, pre-albumin levels and prothrombin time, was within the normal range in all patients except one. Liver biopsies were performed in eight patients. Two biopsies showed cirrhosis, one showed chronic active hepatitis (CAH) with cholestasis, two patients had fibrosis, one showed cholestasis and two biopsies were normal. One patient with cirrhosis and one with CAH were positive for hepatitis C antibody. Another asymptomatic patient was positive for hepatitis B. Only the patient with CAH had hepatic decompensation. We conclude that clinical hepatic failure is uncommon in our group of patients on long-term TPN for 2.5 years or more. Cirrhosis and fibrosis, when found, could not be solely attributed to TPN.

Asymptomatic chronic HBsAg carriers with normal liver function tests are, in general regarded as having no liver pathology. Most of the histologic findings in asymptomatic chronic carriers have been reported from areas with low incidence of Hepatitis B virus (HBV) infection, such as North America and Western Europe. It is well known that there are many differences in HBV infection between low and high endemic areas, but there have been few reports on the histologic findings of asymptomatic chronic HBsAg carriers from endemic areas. The present study was undertaken in Korea which is one of the endemic areas for HBV infection and was designed to assess the prevalence of chronic liver disease by peritoneoscopic liver biopsy among asymptomatic chronic HBsAg carriers and to make a basis for the follow-up of asymptomatic chronic HBsAg carriers according to the results obtained. One hundred and ten asymptomatic HBsAg-positive carriers with normal liver function tests and no hepatomegaly were included in the study. Final diagnosis by peritoneoscopic liver biopsy revealed that of the 110 asymptomatic carriers only 27 (24.5%) had a histologically normal liver, while 51 (46.4%) had chronic liver diseases, and the remaining 32 (29.1%) had nonspecific histologic abnormalities (nonspecific reactive changes in 18 cases, cholestasis in 6 cases, and fatty change in 8 cases). Of the 51 patients with chronic liver diseases, 3 had liver cirrhosis, 4 chronic active hepatitis with cirrhosis, 11 chronic active hepatitis and 33 chronic persistent hepatitis. The frequency of liver cirrhosis and chronic active hepatitis with cirrhosis was significantly high in the over 30 years of age group (12.1%) than in the under 30 years of age group (0%; p = 0.011 by Fisher's exact test). In conclusion, 46.4% of the Korean asymptomatic chronic HBsAg carriers with normal liver function tests and no hepatomegaly had chronic liver disease. This finding contrasted with reports from low incidence areas of HBV infection. Our results suggest that in endemic areas, a liver biopsy should be considered to assess the status of liver disease in asymptomatic chronic HBsAg carriers even if liver function tests are normal and hepatomegaly is absent, and the result can be used as a basis for the follow-up of each asymptomatic chronic HBsAg carriers.

The aetiology, biochemistry, clinical features and complications of histologically confirmed hepatic cirrhosis in 45 patients (26 females, 19 males) seen at the University Hospital of the West Indies, Jamaica, between 1984 and 1994 are presented. The age range was 1 to 72 years (mean 48 years). Abdominal swelling and weight loss were the commonest symptoms, occurring in 51% and 47% of patients, respectively. Jaundice was a presenting feature in 44%. Hepatomegaly was present in 71% of patients and splenomegaly in 33%. The aetiological factors were: alcohol (36%), bush tea (18%), chronic active hepatitis (11%), drugs (7%), and haemochromatosis (2%). Hepatitis B surface antigen was detected in 2 of 20 patients tested. 24% of the patients also had diabetes mellitus., 29% were anaemic, 29% were thrombocytopenic, 4% were leukopenic, and the prothrombin time was prolonged in 22%. The albumin/globulin ratio was reversed in 71% of the patients. The alkaline phosphatase was elevated in 56%, the aspartate aminotransferase was increased in 58% and the gamma glutamyl transpeptidase in 56%. 56% of the patients had macronodular cirrhosis; the liver showed a micronodular pattern in 18%; 7% had biliary cirrhosis; 7% chronic active hepatitis with cirrhosis; and 13% showed a mixed macro-micronodular pattern. Ascites and fluid overload developed in 44% of the patients. Hepatic encephalopathy occurred in 18% and upper gastrointestinal bleeding in 18%.

Recent advances in serodiagnosis of hepatotropic viruses have revolutionized the approach to diagnosis and understanding of chronic liver disease (CLD). There are few studies on CLD in children from India. The present study was planned to define the clinical spectrum of CLD in children, its histopathology and seroepidemiology. Forty children with clinical features satisfying the criteria for diagnosing chronic liver disease were studied. All underwent routine laboratory investigations, liver function tests and ultrasound scan of the abdomen. Liver biopsy, upper GI endoscopy and other special investigations were done wherever indicated. The most common presenting features were jaundice (70%), fever (67%), and abdominal distention (60%). On examination hepatomegaly and icterus (80% each) and splenomegaly (67%) were the commonest findings. Serum transaminases were raised in 62.5% of children while prothrombin time was prolonged in 75% patients. Oesophageal and/or gastric varices were seen in 13 out of 29 patients subjected to upper GI endoscopy. Hepatitis B surface antigen (HbsAg) was positive in 5 children (12.5%) while 3 (7.5%) tested positive for anti HCV antibody. The commonest histopathological diagnosis was infantile cholangiopathy (20%) followed by cryptogenic cirrhosis and idiopathic chronic active hepatitis (17.5% each). The study suggests that the incidence of chronic hepatitis B and C is rather low in childhood. However larger and longer studies are required to delineate the exact incidence of these conditions in childhood and their progression in adolescence and early adulthood.

A case is reported of a 29 year old female who had autoimmune hepatitis associated with mixed connective tissue disease (MCTD). The patient developed MCTD at the age of 19, and was treated with prednisolone. Liver dysfunction developed 7 years later, which exacerbated shortly after the patient suffered intrauterine fetal death during the second trimester of pregnancy. Laboratory data showed negative anti-hepatitis C antibody and hepatitis B antigen, but positive anti-smooth muscle antibody. A liver biopsy showed chronic active hepatitis. Referring to the criteria we diagnosed her as having autoimmune hepatitis. Although hepatomegaly is sometimes observed in MCTD patients, only 5 cases of autoimmune hepatitis associated with MCTD have been reported in the past. In our case, it is of note that autoimmune hepatitis developed while symptoms of MCTD were in remission, and that autoimmune hepatitis exacerbated with the emergence of anti-smooth muscle antibody following the termination of pregnancy.
