In contrast to deficiencies of vitamins A, D and K, little is known of the prevalence, clinical manifestations and mechanisms of vitamin E deficiency in adult patients with cholestasis. We measured serum vitamin E levels in 45 patients with primary biliary cirrhosis, 20 with primary sclerosing cholangitis, 9 with cryptogenic cirrhosis and 12 with alcoholic cirrhosis. To correct for the hyperlipidemia often found in patients with primary biliary cirrhosis and primary sclerosing cholangitis, total serum lipids were measured and vitamin E levels were expressed as the vitamin E/total serum lipid ratio. Serum vitamin A and D levels and prothrombin time were also determined. Six of 45 patients with primary biliary cirrhosis (13%) but none of the patients with sclerosing cholangitis, cryptogenic cirrhosis or alcoholic cirrhosis and subnormal vitamin E/total serum lipids ratios. Vitamin E deficiency was found in two of eight patients with asymptomatic primary biliary cirrhosis. There was no correlation between standard liver biochemical tests, fasting serum cholylglycine and vitamin E levels. Patients with primary biliary cirrhosis and primary sclerosing cholangitis had significantly lower vitamin E/total serum lipids ratios than patients with either cryptogenic or alcoholic cirrhosis. Twenty-three percent of patients with primary biliary cirrhosis were vitamin D deficient and 14% had low vitamin A levels. Two of the six patients with vitamin E deficiency were also deficient in vitamin D, only one was vitamin A deficient and none had prolonged prothrombin time. We also investigated the gastrointestinal absorption of vitamin E in nine patients with primary biliary cirrhosis and normal vitamin E levels as well as in six normal controls.(ABSTRACT TRUNCATED AT 250 WORDS)

In most cases, primary liver carcinoma in tropical areas remains an hepatoma. The high incidence of this malignant tumor of the liver in some regions, and especially in black Africa, is still unexplained. As compared with the form found either in the European or in the North-African, this hepatoma shows special features since it occurs in younger people (35 years), follows a bursting-out course and is precipitously associated not to an alcoholic cirrhosis but to a post-hepatitic one. An humoral syndrome leading to a presomptive diagnosis consists of hypoglycemia, hypercholesterolemia, hyperlipemia, and high blood level of alcaline phosphatases. In 85% of the cases, these tumors secrete an alpha fetoprotein determined by radioimmunoassay. A major etiologic factor is the oncogenous activity of hepatitis virus B which could be either an induction factor or a "co-factor" which would initiate, facilitate or increase the activity of the carcinogen. In this respect, aflatoxin has to be regarded as a "co-factor" too. The best treatment, when it is possible, is an exeresis carried out through a partial hepatectomy. If such a surgical intervention is unadvisable, chemotherapy is the only possibility. Immunization against viral hepatitis has raised hope for the prophylaxis of hepatoma. But it will not be possible to evaluate it before the year 2.000.

Non-alcoholic fatty liver disease (NAFLD) is an increasingly recognized clinico-pathologic entity typically associated with obesity, type II diabetes and hyperlipidemia. It has been noted to recur after orthotopic liver transplantation (OLT). We report four patients who developed de novo NAFLD within 3 months of OLT without the typical predisposing factors of diabetes mellitus or obesity. Three of the four patients underwent OLT for hepatitis C-related cirrhosis, and the other for alcoholic cirrhosis. Examination of the liver explants revealed no evidence of steatosis. No surreptitious alcohol use or a drug-induced process could be identified in these patients. Treatment of recurrent hepatitis C infection in one patient with interferon and ribavirin led to sustained suppression of the viral RNA to undetectable levels, but no improvement in histology or liver enzymes. All four patients had histologic evidence of preservation injury on the initial post-OLT biopsies, but the significance of this finding in relationship to the development of NAFLD is unknown. NAFLD can develop without any of the known predisposing conditions after transplantation, and this raises further questions about the pathogenesis of this condition.

Longer survival for orthotopic liver transplantation (OLT) patients over the last decade has focused emphasis on the metabolic complications that contribute to patient morbidity and mortality. The aim of our study was to analyze the prevalence of the metabolic syndrome (MS) and other risk factors after OLT among our patients at 1 year follow-up. From 2001 to 2008, we performed OLT in 210 patients with 62 exclusions leaving 148 patients for the study. We recorded age, gender, liver disease, smoking status, pre- and post-OLT body mass index, pre- and post-OLT arterial blood pressure, pre- and post-OLT fasting blood glucose, pre- and post-OLT high-density lipoproteins and triglycerides, family history of diabetes, hepatitis B and C virus status, immunosuppressive therapy, and corticosteroid bolus for rejection episodes. The MS was defined according to modified ATP III criteria. At month 12 after OLT, 29/148 patients (19.6%) developed the MS. The associated factors were obesity and hyperlipidemia pre-OLT, familial and personal history of diabetes as well as alcoholic cirrhosis. By multivariate analysis, pre-OLT body mass index (odds ratio, 3.7 [1.3-10.5]) and pre-OLT diabetes (odds ratio, 2.9 [1.1-7.9]) were independent risk factors.
