1 Therefore, prognostic markers of progression to clinical decompensation are needed in patients with compensated cirrhosis. In this population serum albumin, MELD (Model of End-Stage Liver Disease) score and the degree of portal hypertension, as determined by the hepatic venous pressure gradient (HVPG) are independent predictors of first clinical decompensation.2 Obesity is a growing epidemic worldwide, involving 20%-35% of the population in Western countries.3, 4 In addition to known deleterious health
consequences outside the liver,5 obesity is a frequent cause of chronic liver disease that can progress to cirrhosis.6-8 Recent data from a cohort study of middle-aged women in the UK suggested that an estimated 17% of liver cirrhosis is attributable to excess body weight.9 Moreover, patients with cirrhosis due to obesity-related liver disease have a lower survival than patients with viral cirrhosis,10 and there Compound Library is increasing evidence of a deleterious effect of obesity on preexisting chronic liver disease due to hepatitis C virus (HCV), hepatitis B, or alcoholic disease. In these settings obesity has been associated with more advanced fibrosis in cross-sectional studies11, 12 and with faster histological and/or clinical progression in longitudinal studies
of patients with chronic hepatitis C.13, 14 Taken together, these data strongly support find more that obesity per se is a risk factor for progression in the natural history of cirrhosis. Therefore, it can be hypothesized that increased body weight could be an additional risk factor for the transition from compensated to decompensated cirrhosis. However, this hypothesis has not been evaluated and was the objective of this study. BMI, body mass index; CD, clinical decompensation; CLD, chronic liver disease; HVPG, hepatic venous pressure gradient; MELD, Mayo End-Stage Liver Disease score; RCT, randomized controlled MCE公司 trial. The current study was conducted in a subset of patients included in a multicenter randomized controlled trial (RCT) of beta-blockers
in the prevention of varices (timolol study).15 Briefly, between August 1993 and March 1999, patients age 18-75 years old with compensated cirrhosis were enrolled in a prospective placebo-controlled, double-blind RCT designed to evaluate the efficacy of nonselective blockers in preventing the development of gastroesophageal varices in patients with compensated cirrhosis and portal hypertension. Four centers participated in the study: two in the U.S. (New Haven/West Haven and Boston) and two in Europe (Barcelona, London). Patients were considered for inclusion if they had compensated cirrhosis and portal hypertension (defined by an HVPG ≥6 mmHg), without gastroesophageal varices. The diagnosis of cirrhosis was either biopsy proven or clinically suspected and confirmed by the presence of an HVPG ≥10 mmHg.
