BACKGROUND & AIMS Weight regain or insufficient loss after Roux-en-Y gastric bypass (RYGB) is common. This is partially attributable to dilatation of the gastrojejunostomy (GJ), which diminishes the restrictive capacity of RYGB. Endoluminal interventions for GJ reduction are being explored as alternatives to revision surgery. We performed a randomized,(More)
Plasma tumor necrosis factor alpha (TNF alpha), interleukin 1 alpha (IL-1 alpha), and interleukin 1 beta (IL-1 beta) were measured in plasma samples obtained from 23 patients with severe alcoholic hepatitis on admission and after 30 days of hospitalization. Over a 2-year follow-up period, 14 patients died at a mean time of 8 months following discharge. The(More)
BACKGROUND Both the amount and the rate of absorption of ethanol (EtOH) from alcoholic beverages are key determinants of the peak blood alcohol concentration (BAC) and exposure of organs other than gut and liver. Previous studies suggest EtOH is absorbed more rapidly in the fasting than in the postprandial state. The concentration of EtOH and the type of(More)
Dilated cardiomyopathy is a frequent and serious complication of idiopathic hemochromatosis. The mechanism by which disordered iron metabolism induces heart failure is not entirely understood, but myocardial dysfunction appears to be intimately related to the deposition of iron in myocytes. Cardiac function characteristically worsens or improves in(More)
Glutathione (GSH) is important in protection of cells against electrophilic drug injury and against reactive oxygen species. Both steady-state concentrations and turnover of GSH are important determinants of susceptibility of the hepatocyte to injury. Chronic ethanol administration is known to enhance susceptibility to electrophilic drug injury. We have(More)
Chronic ethanol feeding increases hepatotoxicity of drugs, such as acetaminophen, which form electrophilic metabolites. Availability of glutathione (GSH) is important in preventing liver damage from reactive metabolites. Chronic ethanol feeding has been reported to increase turnover of hepatic GSH in rats. The results of the present study show that the(More)
Chronic ethanol feeding increases hepatic turnover and sinusoidal efflux of glutathione in rats. The present study was performed to determine whether the observed increase in glutathione efflux was due to increased extrahepatic requirements for glutathione. The concentration and disposition of plasma glutathione were determined in rats fed liquid diets(More)
Alcohol and dietary intake were determined in alcoholic patients with chronic pancreatitis and alcoholic liver disease. Patients with chronic pancreatitis, alcoholic hepatitis, and cirrhosis ingested approximately 50% of their calories as alcohol, and all had low mean intakes of protein, carbohydrate, and fat as compared with control subjects. Patients with(More)
Plasma acetaminophen elimination was examined in women taking low-dose estrogen oral contraceptive (OC) steroids and in age-matched control women. Fractional rates of elimination and fractional clearances were calculated for each of the metabolic pathways, including oxidation, sulfation, and glucuronidation. The cysteine adduct and mercapturic acid(More)
