Viral clearance in HCV viraemic patients with normal alanine aminotransferase after combination therapy: a controlled, open-labelled study

2004

Summary Background : In patients with chronic hepatitis C virus infection and persistently normal alanine aminotransferase levels, liver fibrosis has been reported in 0–22% of cases and advanced liver disease in 5–10% of cases. Aim : To determine whether patients with persistently normal alanine aminotransferase levels clear infection after anti-viral therapy at equal or different rates from infected patients with raised alanine aminotransferase levels. Methods : Thirty-five hepatitis C virus RNA-positive patients with fibrosis at liver histology (Group 1) were matched for genotype, sex, age and histology with patients with raised alanine aminotransferase levels (Group 2). Both groups were …

Optimal therapy in hepatitis C virus genotypes 2 and 3 patients

2011

Current guidelines recommend that patients with genotype 2 (G2) and 3 (G3) chronic hepatitis C be treated with pegylated interferon (PEG-IFN) plus low doses of ribavirin (800 mg/day) for 24 weeks, resulting in a sustained virological response (SVR) rate of approximately 80%. Considering these high response rates, several recent randomized trials have assessed whether shorter treatment (12–16 weeks) could be cost-effective in these patients. The results of these studies vary but suggest better responsiveness in G2 patients, and overall, do not strongly support reducing treatment to o 24 weeks in all patients. On the other hand, the presence of a rapid virological response (RVR) (defined as a…

Optimized threshold for serum HCV RNA to predict treatment outcomes in hepatitis C patients receiving peginterferon alfa-2a/ribavirin

2012

Summary.  It is unclear whether the current threshold for ‘high’ hepatitis C virus (HCV) RNA level (800 000 IU/mL) is optimal for predicting sustained virological response (SVR). We retrospectively analysed pretreatment HCV RNA levels and SVR rates in 1529 mono-infected and 176 HIV–HCV co-infected patients treated with peginterferon alfa-2a (40 kD) plus ribavirin. We improved the threshold for differentiating low and high viral load by fitting semiparametric generalized additive logistic regression models to the data and constructing receiver operating characteristics curves. Among HCV genotype 1 mono-infected patients, the difference in SVR rates between those with low and high baseline HC…

High sCD36 plasma level is associated with steatosis and its severity in patients with genotype 1 chronic hepatitis C

2012

Soluble CD36 (sCD36) plasma levels, a known marker of cardiometabolic disorders, are associated with surrogate markers of steatosis, while experimental and human studies show a link between CD36 expression in the liver and steatosis. In a cohort of patients with genotype 1 chronic hepatitis C (G1 CHC), we tested the association of sCD36 plasma levels with host and viral factors and sustained virological response (SVR). One hundred and seventy-five consecutive biopsy-proven patients were studied. sCD36 plasma levels were assessed by an in-house ELISA. All biopsies were scored by one pathologist for staging and grading (Scheuer) and graded for steatosis, which was considered moderate-severe i…

The impact of antibiotic resistance on the efficacy of three 7-day regimens againstHelicobacter pylori

2000

Background: Antibiotic resistance affects the success of anti-Helicobacter pylori therapies and varies greatly from country to country. Aim: To compare the efficacy of three short-term triple regimens in relation to H. pylori primary resistance in our region. Methods: We enrolled 210 H. pylori-positive dyspeptic patients for this randomized, open, parallel-group study. Three arms of 70 patients each received the following 1-week regimens: (1) ranitidine bismuth citrate 400 mg b.d. + clarithromycin 250 mg b.d. + metronidazole 500 mg b.d. (RCM); (2) bismuth subcitrate 240 mg b.d. + amoxycillin 1000 mg b.d. + metronidazole 500 mg b.d. (BAM); (3) omeprazole 20 mg o.d. + clarithromycin 250 mg b.…

HCV E1E 2‐ MF 59 vaccine in chronic hepatitis C patients treated with PEG ‐ IFN α2a and R ibavirin: a randomized controlled trial

2013

Hepatitis C virus (HCV) vaccines may be able to increase viral clearance in combination with antiviral therapy. We analysed viral dynamics and HCV-specific immune response during retreatment for experienced patients in a phase Ib study with E1E2MF59 vaccine. Seventy-eight genotype 1a/1b patients [relapsers (30), partial responders (16) and nonresponders (32) to interferon-(IFN)/ribavirin-(RBV)] were randomly assigned to vaccine (V:23), Peg-IFNα2a-180-ug/qw and ribavirin 1000-1200-mg/qd for 48 weeks (P/R:25), or their combination (P/R + V:30). Vaccine (100 μg/0.5 mL) was administered intramuscularly at week 0-4-8-12-24-28-32-36. Neutralizing of binding (NOB) antibodies and lymphocyte prolife…

Head-to-head comparison of 1-week triple regimens combining ranitidine or omeprazole with two antibiotics to eradicate Helicobacter pylori

1999

Background : Triple therapies containing omeprazole and ranitidine have been shown to be equivalent in eradicating H. pylori infection, but have been assessed either separately or head-to-head, only in small trials. Aim : To carry out a large randomized controlled study comparing omeprazole and ranitidine combined with two antibiotic combinations for 1 week. Methods : Three hundred and twenty H. pylori-positive patients were randomly subdivided into four equal-sized groups and received one of the following treatments: OAM = omeprazole 20 mg b.d. + amoxycillin 1 g b.d. + metronidazole 500 mg b.d.; RAM = ranitidine 300 mg b.d. + amoxycillin 1 g b.d. + metronidazole 500 mg b.d.; OAC = omeprazo…

Treatment of acute hepatitis C in human immunodeficiency virus-infected patients: The HEPAIG study

2010

Acute hepatitis C continues to be a concern in men who have sex with men (MSM), and its optimal management has yet to be established. In this study, the clinical, biological, and therapeutic data of 53 human immunodeficiency virus (HIV)-infected MSM included in a multicenter prospective study on acute hepatitis C in 2006-2007 were retrospectively collected and analyzed. The mean hepatitis C virus (HCV) viral load at diagnosis was 5.8 ± 1.1 log10 IU/mL (genotype 4, n = 28; genotype 1, n = 14, genotype 3, n = 7). The cumulative rates of spontaneous HCV clearance were 11.0% and 16.5% 3 and 6 months after diagnosis, respectively. Forty patients were treated, 38 of whom received pegylated interf…
