Upon the delivery of intracellular model antigens,

Upon the delivery of intracellular model antigens, GSK126 concentration hepatocyte-targeted IDLVs induced transgene-specific regulatory T cells that contributed to the observed immune tolerance. Deep sequencing of IDLV-transduced livers showed only rare genomic

integrations that had no preference for gene coding regions and occurred mostly by a mechanism inconsistent with residual integrase activity. Conclusion: IDLVs provide an attractive platform for the tolerogenic expression of intracellular or secreted proteins in the liver with a substantially reduced risk of insertional mutagenesis.

“Obesity is associated with an aggressive course in chronic viral hepatitis; however, its impact in the development of clinical decompensation (CD) in patients with established cirrhosis is uncertain. We evaluated the role of obesity, in relationship to other recognized predictors, in the development of CD in patients with compensated cirrhosis. The study population, a subset of patients included in a randomized trial of beta-blockers in the prevention of varices in whom data on body mass index (BMI) was available, consisted of 161 patients with compensated cirrhosis. Laboratory tests and portal pressure (assessed by the hepatic venous pressure

gradient or HVPG) were assessed on inclusion. Patients were followed until CD (ascites, hepatic encephalopathy, Selleckchem Erlotinib or variceal hemorrhage), or until September 2002. Altogether, 29% had a normal BMI, 40% were overweight, and 30% were obese. In a median follow-up of 59 months, CD occurred in 48/161 (30%) patients with an increasingly higher rate according to BMI group (15% in those with normal BMI; 31% in overweight; 43% in obese patients, P = 0.011). The actuarial probability of developing CD medchemexpress was significantly higher in the abnormal BMI groups (P = 0.022). In a multivariate model that included parameters previously identified as being predictive of CD (HVPG, albumin,

Mayo endstage liver disease score), etiology, and treatment group, BMI (hazard ration 1.06; 95% confidence interval 1.01-1.12), P = 0.02] was an independent predictor of decompensation, together with HVPG and albumin. Conclusion: Obesity has a deleterious effect on the natural history of compensated cirrhosis of all etiologies, independent of portal pressure and liver function. Weight reduction may be a valuable therapeutic measure in this patient population. (HEPATOLOGY 2011;) The natural history of chronic liver diseases is characterized by the progression of fibrosis and nodule formation leading to the development of cirrhosis. Once cirrhosis is established, patients progress from a frequently asymptomatic compensated stage to a decompensated stage, marked by the development of clinical complications of portal hypertension and liver failure.
