Sex difference in the interaction of alcohol intake, hepatitis B virus, and hepatitis C virus on the risk of cirrhosis

2017

Background The joint effect of the interaction of alcohol intake, hepatitis B virus (HBV) and hepatitis C virus (HCV) on the risk of cirrhosis is still unexplored because a large sample size is required for this investigation. Objective Evaluation of interaction of HBV, HCV and alcohol abuse on the risk of cirrhosis. Design We analysed 12,262 consecutive patients with chronic liver disease of various aetiologies referring to 95 Italian liver units in 2001 or 2014. To evaluate the interaction between alcohol abuse, HBV infection, and HCV infection, patients unexposed to either factors were used as reference category. Adjustment for BMI and age was done by multiple logistic regression analysi…

Impact of Safety-Related Dose Reductions or Discontinuations on Sustained Virologic Response in HCV-Infected Patients: Results from the GUARD-C Cohor…

2015

Background: Despite the introduction of direct-acting antiviral agents for chronic hepatitis C virus (HCV) infection, peginterferon alfa/ribavirin remains relevant in many resource-constrained settings. The non-randomized GUARD-C cohort investigated baseline predictors of safety-related dose reductions or discontinuations (sr-RD) and their impact on sustained virologic response (SVR) in patients receiving peginterferon alfa/ribavirin in routine practice. Methods: A total of 3181 HCV-mono-infected treatment-naive patients were assigned to 24 or 48 weeks of peginterferon alfa/ribavirin by their physician. Patients were categorized by time-to-first sr-RD (Week 4/12). Detailed analyses of the i…

PSD3 downregulation confers protection against fatty liver disease

2022

Fatty liver disease (FLD) is a growing health issue with burdening unmet clinical needs. FLD has a genetic component but, despite the common variants already identified, there is still a missing heritability component. Using a candidate gene approach, we identify a locus (rs71519934) at the Pleckstrin and Sec7 domain-containing 3 (PSD3) gene resulting in a leucine to threonine substitution at position 186 of the protein (L186T) that reduces susceptibility to the entire spectrum of FLD in individuals at risk. PSD3 downregulation by short interfering RNA reduces intracellular lipid content in primary human hepatocytes cultured in two and three dimensions, and in human and rodent hepatoma cell…

Comparison of results of combined liver-kidney transplantation vs. isolated liver transplantation

2013

Introduction. Combined liver-kidney transplantation (LKT) is the best therapeutic option for patients with end-stage liver and kidney disease. Objectives. To analyze baseline characteristics and clinical outcome of LKT compared to isolated liver transplantation (LT). Material and methods. The study included 16 LKT performed between 1998 and 2006 and 32 LT matched by age, sex, date and indication for transplantation. Demographic, pretransplant, post-transplant and survival variables were analyzed. Results. As planned by the study design, mean age, distribution by sex and indication for LT were similar between groups. The most common indication for LT was HCV- and/or alcohol-induced cirrhosis…

Metabolomics discloses donor liver biomarkers associated with early allograft dysfunction

2014

Background & Aims Early allograft dysfunction (EAD) dramatically influences graft and patient outcome after orthotopic liver transplantation and its incidence is strongly determined by donor liver quality. Nevertheless, objective biomarkers, which can assess graft quality and anticipate organ function, are still lacking. This study aims to investigate whether there is a preoperative donor liver metabolomic biosignature associated with EAD. Methods A comprehensive metabolomic profiling of 124 donor liver biopsies collected before transplantation was performed by mass spectrometry coupled to liquid chromatography. Donor liver grafts were classified into two groups: showing EAD and immediate g…

Relationship of pre-S encoded antigens in liver and clinical manifestations of chronic hepatitis B infection.

2008

Pre-S1 and pre-S2 encoded antigens of hepatitis B virus were localized in liver tissue using monoclonal antibodies. They were found to be exclusively expressed in the cytoplasm of liver cells. Cell bound pre-S1 encoded protein was often detected in patients with chronic liver disease and viremia. Only a small number of the HBsAg positive cells also contained pre-S1 antigen. There was no correlation with nuclear HBcAg. Livers of non-viremic HBsAg carriers contained many HBsAg expressing liver cells, that were frequently also positive for pre-S2 encoded protein but contained no detectable pre-S1 encoded protein at all. It remains open whether cell bound pre-S2 containing proteins of middle si…

Recent progress and new trends in the treatment of hepatitis B

2002

The annual rate of progression to cirrhosis in patients with chronic HBV is 0.4 to 14.2% and that of death 4 to 10%. HCC risk increases in parallel with the severity and duration of infection, with an annual incidence less than 0.5% in carriers and 6% in patients with cirrhosis. The main aim of antiviral therapy for chronic "wild-type" HBV infection is to suppress viral replication before cirrhosis and HCC develop. Two drugs are approved: IFN alpha and lamivudine. IFN alpha is costly, has a narrow range of efficacy, safety, and tolerability. Lamivudine is active, cheaper, and better tolerated but has limited efficacy, being associated with increasing resistance and loss of clinical response…

Tauroursodeoxycholic acid for the treatment of chronic hepatitis: a multicentre dose-response study

1998

Ursodeoxycholic acid (UDCA) improves the biochemical expression of chronic liver disease. Tauroursodeoxycholic acid (TUDCA) was recently shown to have more favourable metabolic properties. We designed a multicenter, randomized, controlled study, aimed at assessing the efficacy of TUDCA for the treatment of chronic hepatitis. One hundred and fifty-five patients with chronic hepatitis were randomly assigned to receive TUDCA at the daily doses of 250, 500 and 1000 mg, or no treatment for 6 months. Aminotransferase and gamma-glutamyl transpeptidase (GGT) serum levels decreased with each dose of TUDCA compared with controls (P<0.001). The 1000 mg dose was followed by more marked improvement comp…

Prevalence of antibodies to hepatitis C virus among patients with cryptogenic chronic hepatitis and cirrhosis

1992

Many cases of chronic hepatitis and cirrhosis cannot be attributed to a known cause and are collectively referred to as cryptogenic chronic liver disease. We have evaluated the role of the hepatitis C virus in the pathogenesis of this condition in a retrospective serum analysis for antibody to hepatitis C virus in 129 patients with cryptogenic liver disease. Other causes of chronic hepatitis and cirrhosis were ruled out by clinical, serum biochemical and serological techniques. All 129 patients were HBsAg negative, but 28 (22%) had antibody to HBcAg. Sera were tested by radioimmunoassays using recombinant peptides for antibodies to nonstructural (C 100-3 and C33c) and structural regions (C2…
