A case of sudden death associated with fatty liver and encephalopathy is described in a 4-year old white boy with medium-chain acyl-coenzyme A dehydrogenase (MCAD) deficiency. The death was caused by hypoglycemia triggered by fasting and vomiting associated with a minor viral infection. The differential diagnosis of the hepatoencephalopathy is discussed in relation to other conditions, especially Reye's syndrome. The forensic pathologist should be familiar with MCAD and other deficiencies of beta-oxidation of fatty acids as a cause of sudden unexpected death in children in order to advise parents in genetic counseling to prevent disability or death of other affected, but still asymptomatic siblings.

To investigate the prevalence of antibody to hepatitis C virus (anti-HCV) in heavy drinkers with liver disease in Japan, we tested serum samples from 113 heavy drinkers with liver disease and 121 without liver disease. All were negative for HBsAg with no history of blood transfusion. These subjects had consumed more than 80 g of ethanol daily for 5 years or more. Findings for anti-HCV determined by recombinant immunoblot assay testing were positive in 14 (35.9%) of the 39 patients with liver cirrhosis, 14 (58.3%) of the 24 patients with hepatocellular carcinoma and in 8 (53.3%) of the 15 patients with chronic hepatitis. The anti-HCV positive rate in the drinkers with these liver diseases was significantly higher than in those with such disorders as fatty liver (0/10), hepatic fibrosis (0/22), and alcoholic hepatitis (0/3), as well as in the alcoholics without liver disease (5/121, 4.2%). Considering histologic findings in the anti-HCV positive cirrhotics, the occurrence of lymph follicle formation (71.4%), piecemeal necrosis (78.6%) and loose fibrosis (64.3%) were observed to a significantly higher extent than in cirrhotics who were negative for anti-HCV. These findings suggest that advanced chronic liver disease among heavy drinkers in Japan, especially of hepatocellular carcinoma, is closely associated with HCV infection. In the livers of heavy drinkers who were positive for anti-HCV, histologic findings indicated the possibility of viral infection.

A 3-year-old girl in whom severe acute pancreatitis was associated with evidence of Coxsackie B4 virus infection was alpha-1-antitrypsin deficient. Lack of this modulator of proteolysis may have been responsible for her severe course. Fatty liver at presentation progressed to cirrhosis in the ensuing 18 months.

Reye's syndrome (RS) is generally considered a childhood disease. We report our experience with RS in adults in the metropolitan Milwaukee area. Reye's syndrome was diagnosed in seven 18- to 46-year-old adults. The diagnostic criteria were as follows: viral prodrome followed by vomiting and encephalopathy without focal neurological signs, normal cerebrospinal fluid values, increased levels of serum aminotransferases (transaminase), prolonged prothrombin time, elevated blood ammonia levels, and characteristic microvesicular fatty liver and mitochondrial changes. None of the patients was hypoglycemic. The diagnosis of RS was entertained in 22 but confirmed in only seven patients. In cases of non-Reye's encephalopathy, drug ingestion presented as one of the most difficult differential diagnostic problems, which also included alcohol abuse, collagen vascular disease, and hepatitis B surface antigenemia. Clinical jaundice, distinctly uncommon in RS, was present in only one patient who presented to us in stage V coma. In adults, RS is more difficult to diagnose and should be suspected more frequently in patients with unexplained altered behavior following a viral illness and vomiting. Liver biopsy can be performed safely and is usually mandatory in adults. Patients with RS diagnosed during stage I or II coma and treated experienced an uneventful recovery.

Liver disease in 193 patients (17 male and 176 female) with systemic lupus erythematosus (SLE) at Kawasaki Municipal Hospital were analyzed. Abnormal transaminase levels were found in 78 case (40.4%). Among them, there were 35 patients whose liver disease were identified. There were 12 patients whom no cause could be found other than SLE. Other liver disease were as follows: fatty liver in 9 cases, virus infection in 5 cases, gall stone and/or cholecystitis in 3 cases, drug allergy in 2 cases, autoimmune hepatitis 2 cases, primary biliary cirrhoses in 1 case. Liver disease with systemic lupus erythematosus was frequent, but there was no severe case.

The aim of the present was to define prognosis and life expectancy in patients with chronic liver disease of different etiologies and to relate them to an age- and sex-matched normal population. After a follow-up of 15 years, life expectancy of 620 patients with chronic liver disease was retrospectively calculated and compared with an age- and sex-matched normal population. Among patients with cirrhosis, prognosis was dependent upon Child classification (P = 0.001). Patients with alcoholic cirrhosis and fatty liver disease were younger (P = 0.01) and had a lower life expectancy than patients with other causes of chronic liver disease (P = 0.004). Patients with hepatitis B and hepatitis C cirrhosis showed a comparable prognosis and a significantly lower life expectancy than the age- and sex-matched population. Cryptogenic and autoimmune liver diseases showed a comparable life expectancy but a significantly shorter life expectancy than the normal population. In patients with alpha 1-antitrypsin deficiency-associated cirrhosis, a high viral coinfection rate was found (P = 0.01). For patients with noncirrhotic hemochromatosis, prognosis was poorer than that for the age- and sex-matched population. In patients with asymptomatic primary biliary cirrhosis, chronic persistent hepatitis B, and alpha 1-antitrypsin deficiency without cirrhosis, life expectancy was equal to that of the normal population. Prognosis and life expectancy in chronic liver disease depend on stage, cause, and symptoms of chronic liver disease; age; and possibilities of treatment. In patients with hereditary liver disease, additional viral infection of alcohol abuse lead to a significant deterioration of life expectancy. Patients with alcoholic chronic liver disease have the poorest prognosis.

The influence of hepatitis C virus and its subtypes on the clinical course of liver disease in alcoholics was assessed. Hepatitis C virus infection was confirmed by a reverse transcription and polymerase chain reaction method for the hepatitis C virus NS-5 region in the sera of alcoholics with various stages of histologically proven liver disease. The frequency of hepatitis C virus was significantly higher in alcoholics with chronic hepatitis (73%) than in those with liver fibrosis (18%), alcoholic hepatitis (17%), and fatty liver (0%). Hepatitis C virus subtypes, namely K1 and K2, were determined by dot-blot hybridization analysis of the polymerase chain reaction products with specific probes, and their frequencies were 68% and 32%, respectively. The proportion of patients whose serum transaminase levels returned to normal following 4 weeks of abstinence in hospital was significantly lower in alcoholics with hepatitis C virus viremia (glutamic oxaloacetic transaminase: 53.8%; glutamic pyruvic transaminase: 42.3%) than in those without viremia (glutamic oxaloacetic transaminase: 86.2%, p < 0.01; glutamic pyruvic transaminase: 89.7%, p < 0.01). When alcoholics with the K1 and K2 subtypes of hepatitis C virus were compared, normalization of transaminase levels was less frequent in alcoholics with K1 (glutamic oxaloacetic transaminase: 42.8%; glutamic pyruvic transaminase: 28.6%) than in those with K2 (glutamic oxaloacetic transaminase: 88.9%, p < 0.05; glutamic pyruvic transaminase: 77.8%, P < 0.05). These data indicate that hepatitis C virus infection is associated with a reduced rate of recovery of serum transminase levels following abstinence in subjects with alcoholic liver disease, more so in the K1 subtype than in the K2 subtype.

We evaluated hepatitis B virus DNA and hepatitis C virus RNA in sera from 110 HBsAg and IgM HBc antibody-negative heavy drinkers (50 cirrhosis, 13 chronic active hepatitis, 25 fatty liver with or without mild to moderate fibrosis, alcoholic hepatitis or both and 22 healthy alcoholic subjects) with polymerase chain reaction. Results of hepatitis C virus polymerase chain reaction were compared with those obtained with two tests (second generation recombinant immunoblot assay and enzyme-linked immunosorbent assay) used to detect hepatitis C virus antibodies. Hepatitis B virus DNA was found in three (2.7%) patients. Hepatitis C virus RNA was detected in 29 (29.8%) of the 97 subjects whose sera were well preserved for RNA extraction (42.5% cirrhosis, 83.3% chronic active hepatitis, 8% fatty liver and 0% healthy alcoholic subjects). Results obtained with second-generation recombinant immunoblot assay and enzyme-linked immunosorbent assay had a high degree of agreement with polymerase chain reaction as expected, the kappa indexes being 0.76 and 0.61, respectively. Nevertheless, five hepatitis C virus RNA-positive patients had negative recombinant immunoblot assay results, whereas all hepatitis C virus RNA-positive patients had positive or borderline enzyme-linked immunosorbent assay results. We conclude that, in Italian HBsAg-negative alcoholic patients, "inapparent" hepatitis B virus infection is rare. On the contrary, hepatitis C virus infection, as detected on hepatitis C virus polymerase chain reaction, is quite frequent, especially in patients who have cirrhosis and chronic active hepatitis.(ABSTRACT TRUNCATED AT 250 WORDS)

Hepatic dysfunction is common in patients who receive intensive chemotherapy and it is important to determine the etiology in order to institute appropriate therapy. The role of laparoscopic liver biopsy in patients with neutropenia, thrombocytopenia, or both was evaluated as a mean of making treatment decisions and as a determinant of clinical outcome. Laparoscopic liver biopsy was performed in 29 subjects who were receiving intensive cytotoxic therapy with or without bone marrow transplantation. One to three direct-vision laparoscopic liver biopsies were performed in each patient using a Tru-cut needle during general anesthesia. Platelet concentrate transfusions were usually given before, during, and immediately after biopsy. Bleeding was controlled with spatula electrocautery. Thirty-two biopsies were obtained in 29 patients. At the time of liver biopsy, white blood cell and platelet counts ranged from 0 to 14,300/microliters (median: 2500/microliters), and 1000 to 47,000/microliters (median: 20,000/microliters), respectively. Bleeding at the liver biopsy site was readily controlled during the procedure without clinical evidence of significant bleeding; no procedure-related complications were noted and no patients required re-exploration. All biopsies were informative and the lesions observed in 32 biopsies revealed graft-versus-host disease (n = 5), hepatic candidiasis (n =1), hepatic veno-occlusive disease (n = 3), cholestasis (n = 19), hemosiderosis (n = 26), toxic injury (n = 8), hepatic steatosis (n = 4), granuloma (n = 1), viral infection (n =1), and malignancy (n = 1). Laparoscopic liver biopsy has been proven to be an effective means of assessing the cause of liver dysfunction in patients who were thrombocytopenic and immunosuppressed. The diagnosis obtained at laparoscopic liver biopsy altered therapy in nine of 29 (31%) patients.

Hepatitis C virus (HCV) infection is one of the major causes leading to orthotopic liver transplantation (OLT) worldwide. Although viral infection persists in almost all patients, the pathology of recurrent HCV infection after OLT is not well characterized. To address this issue, we compared the pathological findings of 28 patients who underwent transplantation for HCV-related cirrhosis (group A, aged 47 +/- 15 years; 23 men, 5 women) with those of 21 patients who underwent transplantation for nonviral indications (group B, aged 45 +/- 21 years; 13 men, 8 women) during the first year after transplantation. Patients from group A were assessed for serum HCV RNA by 5' untranslated region nested polymerase chain reaction before and 1 year after OLT. Patients underwent protocol liver biopsies 3 months and 1 year after transplantation. Group A patients more frequently had histological evidence of hepatic steatosis than group B patients, both at 3 months (P = .003) and 1 year (P = .003) after OLT. Fibrosis and portal inflammation were statistically more frequent in group A 1 year after transplantation. The sensitivity of steatosis in detecting histological disease recurrence was 100% at 3 months and 94% at 1 year; the specificity was 40% and 60%, respectively. Conversely, steatosis was 100% specific in detecting viral recurrence, with a sensitivity of 89%. The 1-year actuarial incidence of abnormal transaminase levels was 52% in group A and 13% in group B (P = .05). No biochemical or histological differences between patients infected with genotype 1b and patients with other HCV genotypes were found. Hepatic steatosis is a specific sign of viral recurrence after liver transplantation and a less specific sign of disease recurrence. HCV-infected liver transplant recipients often develop abnormal transaminase levels and liver fibrosis 1 year after OLT; these features are unrelated to HCV genotypes.
