BACKGROUND & AIMS Patients with cirrhosis hospitalized for an acute decompensation (AD) and organ failure are at risk for imminent death and considered to have acute-on-chronic liver failure (ACLF). However, there are no established diagnostic criteria for ACLF, so little is known about its development and progression. We aimed to identify diagnostic(More)
AIMS The gamma-aminobutyric acid (GABA(B)) receptor agonist, baclofen, has recently been shown to reduce alcohol intake in alcohol-preferring rats and alcohol consumption and craving for alcohol in an open study in humans. The present study was aimed at providing a first evaluation of the efficacy of baclofen in inducing and maintaining abstinence and(More)
BACKGROUND It is not established whether virological status affects the efficiency of alpha-fetoprotein (AFP) as a hepatocellular carcinoma (HCC) marker among patients with chronic liver disease (CLD). METHODS We enrolled in a case-control study 170 HCC and 170 CLD patients, matched for age, sex, CLD and HBsAg/anti-HCV status. The AFP sensitivity,(More)
BACKGROUND/AIMS The current approaches to study the molecular mechanisms involved in the pathophysiology of liver diseases often rely on the use of transgenic mice. However, experimental models of decompensated cirrhosis have not been clearly established in mice. Thus, we aimed to set an efficient and well-tolerated protocol to induce cirrhosis in mice able(More)
BACKGROUND Ghrelin is a peptide produced mainly by the gut and hypothalamus. Ghrelin is able to stimulate food-seeking behavior. Alcohol-craving and food-seeking behavior could share common neural circuits. Ghrelin is related to nutritional status, but few data are available in alcoholic patients on the relationship between ghrelin and nutritional(More)
BACKGROUND/AIM Endotoxaemia can complicate hepatic ischaemia-reperfusion (IR) injury. Endocannabinoids appear to modulate the haemodynamic alterations and cytokine response induced by lipopolysaccharide (LPS). Thus, we aimed to determine the effect of the endocannabinoid CB1-receptor antagonist Rimonabant in a model of hepatic IR injury complicated by(More)
Hepatic steatosis is associated with mitochondrial oxidative alterations. This study aimed to characterize in a choline-deficient model of rat fatty liver whether this oxidative imbalance is related to an impairment of the capacity of ATP synthesis both under fed conditions and after starvation, which may sensitize mitochondria to oxidative injury.(More)
BACKGROUND Whether fatty infiltration of the liver influences the generation of reactive oxygen species (ROS) during reperfusion is unclear. Thus, this study aimed to compare the ROS formation that occurs during postanoxic reoxygenation in isolated normal and fatty livers. METHODS Isolated livers from fed Sprague-Dawley rats with normal or fatty livers(More)
Mitochondria undergo oxidative damage during reperfusion of ischemic liver. Although nutritional status affects ischemia-reperfusion injury in the liver, its effect on mitochondrial damage has not been evaluated. Thus, this study was designed to determine whether starvation influences the oxidative balance in mitochondria isolated from livers exposed to(More)
BACKGROUND & AIMS Bloodstream infections (BSIs) in cirrhotic patients are 10-fold more common than in non-cirrhotic patients and increasingly caused by resistant pathogens. We examined 162 BSI episodes in cirrhotic patients to describe the etiology and risk factors for 30-day mortality. METHODS We retrospectively analyzed all consecutive BSIs in patients(More)
