Direct antiviral agents in hepatitis C virus related liver disease: Don’t count the chickens before they’re hatched
2021
Since molecules with direct-acting antiviral (DAA) became available, the landscape of the treatment of hepatitis C virus (HCV) infection has completely changed. The new drugs are extremely effective in eradicating infection, and treatment is very well tolerated with a duration of 8-12 wk. This review aims to report the outstanding clinical benefits of DAA and to highlight their critical disadvantages, identifying some clinically relevant hot topics. First, do the rates of virological response remain as high when patients with more advanced cirrhosis are considered? Large studies have shown slightly lower but still satisfactory rates of response in these patients. Nevertheless, modified sche…
Predicting sustained virological responses in chronic hepatitis C patients treated with peginterferon alfa-2a (40 KD)/ribavirin.
2005
Background/Aims: Prediction of sustained virological response (SVR) during treatment would allow clinicians to identify patients most likely to benefit from therapy. Methods: Retrospective analysis of data from 1121 adults with chronic hepatitis C treated for 48 weeks with peginterferon alfa-2a (40 KD) 180 mu g/week plus placebo or ribavirin (1000/1200 mg/day), or interferon alfa-2b 3 MIU three times/week plus ribavirin in a randomized, multinational, study. Results: 67% of patients treated with peginterferon alfa-2a (40 KD)/ribavirin with early virological responses (HCV RNA negative or >= 2 log(10) decrease) at week 12 had SVRs at week 72 (HCV RNA 80 % of the planned ribavirin dose.

Direct-acting antivirals for hepatitis C virus infections in patients co-infected with human immunodeficiency virus
2011
Summary Nearly three-quarters of human immunodeficiency virus–hepatitis C virus (HIV-HCV) coinfected patients in France currently need to be cured of their chronic HCV infection. The increase in sustained virological response rates obtained with the recently available HCV protease inhibitors in treatment-naive genotype-1 patients has generated considerable hope in these co-infected patients. However, several particularities (such as a higher baseline HCV load, more advanced liver fibrosis, frequent co-morbidities, and the risk of toxicity and drug–drug interactions) have not allowed the direct extrapolation of the results observed in HCV-monoinfected patients to patients with HIV-HCV co-inf…
Direct-acting antiviral-based therapy for chronic hepatitis C virus in HIV-infected patients
2015
The aim of this review was to detail the current therapies and treatments for chronic hepatitis C virus in coinfected patients, focusing on HCV antiviral agents currently used in practice today or scheduled to enter the open market soon. Several direct-acting antiviral (DAA) combinations show high sustained virologic response (SVR) rates in HIV/HCV-coinfected patients, which are often close to those observed in HCV-monoinfected patients. Most recommendations regarding treatment stem from trials with coinfected patients. However, data are lacking for some aspects of HCV-treatment in coinfection, so extrapolations must be made from data obtained predominately from monoinfected patients. HIV/H…
Significant reductions in alcohol use after hepatitis C treatment: results from the ANRS CO13-HEPAVIH cohort
2017
BACKGROUND AND AIMS: Few data exist on changes to substance use patterns before and after hepatitis C virus (HCV) treatment. We used longitudinal data of HIV-HCV co-infected individuals to examine whether receiving pegylated interferon (Peg-IFN)-based therapy irrespective of HCV clearance could modify tobacco, cannabis and alcohol use. DESIGN: A prospective cohort of HIV-HCV co-infected individuals was enrolled from 2006. Participants' clinical data were retrieved from medical records and socio-demographic and behavioural characteristics were collected by yearly self-administered questionnaires. SETTING: Data were collected across 17 hospitals in France. PARTICIPANTS: All HIV-HCV co-infecte…
Patient-to-patient transmission of hepatitis C virus (HCV) during colonoscopy diagnosis
2010
Abstract Background No recognized risk factors can be identified in 10-40% of hepatitis C virus (HCV)-infected patients suggesting that the modes of transmission involved could be underestimated or unidentified. Invasive diagnostic procedures, such as endoscopy, have been considered as a potential HCV transmission route; although the actual extent of transmission in endoscopy procedures remains controversial. Most reported HCV outbreaks related to nosocomial acquisition have been attributed to unsafe injection practices and use of multi-dose vials. Only a few cases of likely patient-to-patient HCV transmission via a contaminated colonoscope have been reported to date. Nosocomial HCV infecti…
Peginterferon-Α_2B plus ribavirin is more effective than peginterferon-Α_2A plus ribavirin in menopausal women with chronic hepatitis C
2012
Summary. Under-enrolment of women to randomized clinical trials, including chronic hepatitis C, has long been recognized. The aim of this study was to identify factors predictive of sustained virological response (SVR) to PEG IFN/Ribavirin antiviral therapy in relation to gender and reproductive status of female patients involved. Seven hundred and forty-six treatment-naive patients (431 men, 315 women) treated with Peg-IFNα-2a (180 μg/week) or Peg-IFNα-2b (1.5 μg/kg/week) plus ribavirin (800–1400 mg/day) for 24 or 48 weeks were studied between 2006 and 2010. Differences in SVR rate, overall and by gender were assessed after adjustment and propensity score matching. SVR was obtained in 44…
Myocardial fibrosis by delayed enhancement cardiovascular magnetic resonance and HCV infection in thalassemia major patients.
2010
Abstract Abstract 4265 Introduction. Delayed enhancement (DE) cardiac magnetic resonance (CMR) technique with intravenous administration of gadolinium (Gd) chelates contrast agents is the only validated non-invasive approach for detecting myocardial fibrosis (Mahrholdt H et al, Eur Heart J 2005). This technique has been confirmed safe in patients with hemoglobinopathies (Meloni A et al, Haematologica 2009). In thalassemia major (TM), myocardial fibrosis has been detected using the DE technique and a positive correlation with anti-HCV antibodies has been described (Pepe A et al, Heart 2009). However, HCV-induced cardiomyopathy is still controversial (Matsumori A et al. J Card Fail 2006). The…
Telaprevir drug monitoring during antiviral therapy of hepatitis C graft infection after liver transplantation
2014
Background & Aims Recurrence of hepatitis C virus (HCV) infection after orthotopical liver transplantation (OLT) is common and associated with reduced graft and patient survival. The protease inhibitor telaprevir may enhance virological response rates in patients after OLT in combination with pegylated interferon-alfa and ribavirin. Pharmacokinetic studies have shown significant drug–drug interactions between telaprevir and immunosuppression (IS), but telaprevir pharmacokinetics in OLT patients with IS are unknown. Aim of the present study was to analyse telaprevir plasma concentrations in patients with HCV genotype 1 infection after OLT in comparison to patients without OLT and IS. Methods…
Hepatocellular cancer: optimal strategies for screening and surveillance.
2009
Hepatocellular carcinoma (HCC) is a challenging malignancy of global importance and is associated with a high rate of mortality. Individuals with chronic viral hepatitis and other forms of liver disease are at risk for developing HCC. The stage of cancer dictates the therapeutic choice, making early detection a primary objective. Many observational studies have reported that HCC is diagnosed at an earlier stage in patients who received surveillance. The guidelines of the American Association for the Study of Liver Diseases suggest that surveillance should be performed using ultrasonography at an interval of every 6–12 months. This interval is based upon mainly observational data and the exp…
