Quantification of HBsAg to predict low levels and seroclearance in HBeAg-negative patients receiving nucleos(t)ide analogues.

Background: HBeAg-negative chronic hepatitis B patients require long-term nucleos(t)ide analogues(NAs) because loss of surface antigen (HBsAg) is unusual. Low quantitative HBsAg (qHBsAg) levels can identify patients with higher probability of seroclearance. The aim of our study was to evaluate qHBsAg in HBeAg-negative patients receiving NAs to predict a reduction of HBsAg levels and seroclearance.

Diagnostic Accuracy of the Enhanced Liver Fibrosis (ELF®) Score Using HCV-Infected Serum Samples Cryopreserved for up to 25 Years.

Introduction & Aims: Cryopreservation of serum samples is a standard procedure for biomedical research in tertiary centers. However, studies evaluating the long-term biological stability of direct liver fibrosis markers using cryopreserved samples are scarce.

Methods: We compared the stability of hyaluronic acid (HA), tissue inhibitor of metalloproteinases (TIMP-1) and amino-terminal propeptide of type III procollagen (PIIINP) in 225 frozen serum samples of HCV-infected patients with a paired liver biopsy for up to 25 years (1990-2014).

A multidisciplinary support programme increases the efficiency of pegylated interferon alfa-2a and ribavirin in hepatitis C.

Background & Aims: Adherence to antiviral treatment is important to achieve sustained virological response (SVR) in chronic hepatitis C (CHC). We evaluated the efficiency of a multidisciplinary support programme (MSP), based on published HIV treatment experience, to increase patient adherence and the efficacy of pegylated interferon alfa-2a and ribavirin in CHC.

Methods: 447 patients receiving antiviral treatment were distributed into 3 groups: control group (2003-2004, n=147), MSP group (2005-2006, n=131), and MSP-validation group (2007-2009, n=169).

Poor response to hepatitis C virus (HCV) therapy in HIV- and HCV-coinfected patients is not due to lower adherence to treatment.

The degree of adherence to anti-hepatitis C virus (HCV) therapy among HIV/HCV-coinfected patients is not known. A prospective cohort study was performed in two groups of patients: 79 HIV/HCV-coinfected patients (group 1) and 78-HCV-monoinfected patients (group 2). Patients were treated with interferon alpha-2a (3 million international units [MIU], three times per week) plus ribavirin (1000-1200 mg/day) for 48 weeks.
