OBJECTIVES In experimental models, liver injury induced by ethanol, cytotoxic activity of tumor necrosis factor (TNF) -alpha is principally mediated by TNF receptor p55 (TNFRp55). Among the various mechanisms underlying the toxic effects of TNF-alpha, overproduction of reactive oxygen species seems to play a key role in mediating TNF-alpha-induced(More)
Though the hepatotoxicity of ethanol has been established, only 8% to 20% of chronic alcoholics develop cirrhosis. The aim of this study was to assess whether being overweight is a risk factor for alcoholic liver disease. One thousand six hundred four alcoholic patients were studied. According to the liver biopsies, 194 patients had a normal liver; 402 had(More)
BACKGROUND & AIMS Involvement of an abnormal von Willebrand factor in the bleeding expression of gastrointestinal angiodysplasias has been suggested but not assessed by prospective studies. METHODS To address this issue, 27 patients with either nonbleeding (group A, n = 9) or bleeding (group B, n = 9) digestive angiodysplasias or telangiectasias or(More)
BACKGROUND AND AIMS Excessive alcohol consumption is a risk factor for developing colorectal adenomas. This study aimed to investigate the influence of excessive alcohol consumption on the occurrence of high risk polyps (adenoma > or = 10 mm, villous component, high grade dysplasia) or colorectal cancer among patients with at least one colonic adenoma.

Bone marrow examination revealed a lipid-laden histiocytosis in seven patients undergoing long-term total parenteral nutrition necessitated by extensive short-bowel surgical resection. Clinical abnormalities occurred during this treatment which required bone marrow examination. These included hepatosplenomegaly and peripheral blood cytopenia; the median(More)
OBJECTIVES To describe the characteristics of in-patients with alcoholic liver disease in Hepatogastroenterology and to evaluate whether geographic location was a risk factor for cirrhosis. METHODS A French, national, multicenter, prospective investigation was performed in the last quarter of 1997. To be included in the study, patients had to have drunk(More)
Between March 1997 and March 1998, three consecutive patients underwent laparoscopic cystogastrostomy for persistent giant retrogastric pancreatic pseudocyst complicating an attack of acute pancreatitis. The mean cyst diameter was 15 +/- 1 cm (range 14-16). The procedure was performed with four trocars. The anterior wall of the stomach was opened(More)
BACKGROUND/AIMS The mechanism of action of recombinant interferon-alpha (rIFN alpha) treatment in chronic hepatitis C is not fully understood, and may include modulation of the immune system as well as a direct antiviral effect. We have therefore evaluated the plasma concentrations of pro- and anti-inflammatory cytokines in patients with chronic hepatitis C(More)
BACKGROUND/AIMS Correlations between serum levels of soluble tumor necrosis factor receptors p55 (TNFsRp55) and Child Pugh index have previously been reported in alcoholic patients with cirrhosis. We have undertaken this study to improve understanding of the role of tumor necrosis factor soluble receptors (TNFsRs) in alcoholic liver disease. METHODS One(More)
