OBJECTIVE: Data of hepatitis C treatment with direct-acting antivirals (DAAs) in HIV infected patients are limited to a few number of antiretroviral therapies (ART). The aim of this study was to assess the effectiveness and safety of non-conventional ART as monotherapy or dual therapy (MDT) when combined with DAA. METHODS: Retrospective review of HIV/HCV-coinfected patients treated with DAAs during one year in 3 centers. Sustained virologic response 12 weeks after therapy (SVR) and maintenance of HIV viral suppression were compared between patients receiving triple ART (TT) or MDT...

Background: The efficacy of direct-acting antivirals (DAAs) depends on the hepatitis C virus (HCV) genotype 4 (GT4) subtype which are used in the treatment of HCV. We aimed to retrospectively investigate the baseline prevalence of HCV NS5A and NS5B polymorphisms and their impact on virological outcome in GT4-infected patients treated with various DAA regimens. Patients and methods: Available plasma samples from HCV GT4-infected patients treated with different DAA regimens were analyzed at baseline and after treatment failure, where applicable...

Background: Direct-acting antiviral agents (DAAs) permit the use of interferon (IFN)-free regimens to treat hepatitis C (HCV) in patients with chronic kidney disease (CKD) on hemo-dialysis (HD) or renal transplant (RTx) recipients, with excellent response rates and safety. However, the occurrence of basal or therapy-induced resistance-associated substitutions (RASs) to DAAs can result in treatment failure. The aim of this study was to estimate the prevalence of RASs to NS3A, NS5A and NS5B inhibitors, and particularly the Q80K polymorphism, in CKD patients on HD and RTx recipients infected with HCV...

Hepatitis C virus (HCV) infection is more prevalent and is associated with higher mortality in patients receiving dialysis and in kidney transplant recipients than in the general population. Kidney transplant recipients who are HCV-positive are also at higher risk of allograft and liver failure than are HCV-negative recipients. Moreover, HCV infection is associated with a higher incidence and faster progression of diabetes mellitus and chronic kidney disease (CKD), as well as a higher incidence of systemic (especially cardiovascular) complications...

The role of the endogenous interferon (IFN) system has been well characterized during IFN-based therapy for chronic hepatitis C virus (HCV) infection; less is known for direct-acting antivirals (DAAs). In this phase 3b open-label study, we assessed changes in IFN-stimulated genes (ISGs) in non-cirrhotic treatment-naïve or pegIFN/RBV-experienced HCV-GT1a-infected patients receiving paritaprevir/ritonavir/ombitasvir+dasabuvir+ribavirin (PrOD+R) for 12 weeks. ISG expression was quantified from PBMCs at baseline, treatment weeks (TW)2, TW4, TW8, end-of-treatment (EOT) and at post-treatment week 12...

Direct-acting a antiviral (DAA) are currently used in the treatment of chronic HCV infection. In patients with renal failure with Elbasvir/Grazoprevir (genotype 1 and 4) or Pibrentasvir/Glecaprevir (genotype 1-6) is advised and these documented both good safety and efficacy. In this manuscript we reported the development of cholestatic jaundice, during Pibrentasvir/Glecaprevir treatment, in a 86-year-old male with chronic HCV (genotype 2) infection and renal failure. At examination patient was jaundiced and suffered of a severe itch...

The introduction of new multi-genotypic direct acting antivirals (DAA) in clinical practice has revolutionized HCV treatment, permitting the achievement of >95% rates of sustained virological response in many patients. However, virological failures can occur particularly if the treatments are sub optimal and/or with too short duration. Failure is often associated with development of resistance. The wide genetic variability in terms of different genotypes and subtypes, together with the natural presence and/or easy development of resistance during treatment, are intrinsic characteristics of HCV that may affect the treatment outcome and the chances of achieving a virological cure...

European treatment guidelines for hepatitis C virus (HCV) infection recommend that people with genotype (GT)1a infection and baseline viral load ≤800,000 IU/mL receive elbasvir/grazoprevir (EBR/GZR) for 12 weeks, and those with baseline viral load >800,000 IU/mL receive EBR/GZR plus ribavirin for 16 weeks. This analysis was conducted to clarify whether baseline viral load can serve as an accurate, sensitive, or specific stratification factor for defining EBR/GZR regimens. In this post hoc, integrated analysis, participants with GT1a infection who received EBR 50 mg/GZR 100 mg for 12 weeks were stratified according to baseline viral load...

BACKGROUND: Fibrosing cholestatic hepatitis (FCH) is an aggressive form of hepatitis C virus (HCV) recurrence after liver transplantation (LT). Most FCH cases are fatal, occurring as a secondary disease following rapidly progressive liver dysfunction and graft failure. We report a case of early-onset FCH after LT that was successfully treated using daclatasvir and asunaprevir. CASE REPORT: A 59-year-old woman underwent living donor LT for HCV-related liver cirrhosis...

In Pakistan, the burden of the hepatitis C virus (HCV) infection is the second highest in the world with the development of chronic hepatitis. Interferon-based combination therapy with ribavirin was the only available treatment until a few years back, with severe side-effects and high failure rates against different genotypes of HCV. Interferon-free all-oral direct-acting antiviral agents (DAAs) approved by the FDA have revolutionized the HCV therapeutic landscape due to their efficiency in targeting different genotypes in different categories of patients, including treatment naïve, treatment failure and relapsing patients, as well as patients with compensated and decompensated cirrhosis...

Treatment of chronic hepatitis C virus (HCV) infection with direct acting antivirals (DAAs) results in a sustained virologic response (SVR) in most patients. While highly efficacious, ~3-5% of patients do not achieve SVR despite having virus that appears susceptible. It is unclear whether host factors contribute to treatment failures, although innate and adaptive immunity may play a role. Previous studies showed that after DAA treatment, the composition of intrahepatic immune cells does not normalize relative to healthy volunteers, even in cases where SVR is achieved...

BACKGROUND: Optimal treatment for patients with hepatitis C virus (HCV) genotype-3 infection and liver cirrhosis remains a medical priority. Daclatasvir+sofosbuvir and ribavirin is a recommended option for such patients, but clinical trial data are lacking for treatment >16 weeks. METHODS: This was a single-arm, Phase III study of daclatasvir+sofosbuvir+ribavirin for 24 weeks in patients with compensated cirrhosis and HCV genotype-3 infection. The primary endpoint was sustained virological response at post-treatment week 12 (SVR12); the primary objective was to demonstrate statistical superiority to historical SVR12 data for 12 weeks' daclatasvir+sofosbuvir without ribavirin in genotype-3-infected patients with cirrhosis (95% confidence interval [CI] lower bound >79...

Chronic infection with hepatitis C virus (HCV) is a major cause of liver disease and hepatocellular carcinoma worldwide. Following the discovery of HCV 3 decades ago, the identification of the structure of the viral proteins, combined with high-throughput replicon models, enabled the discovery and development of direct-acting antivirals. These agents have revolutionized care of patients, with cure rates of more than 90%. We review the status of direct-acting antiviral therapies for HCV infection and discuss remaining challenges...

Direct acting antivirals have completely changed the landscape of the treatment of chronic hepatitis C. The management of the few patients who relapse to direct acting antivirals requires a careful analysis of the chances to achieve therapeutic success with a second antiviral course. In this context, the usefulness of viral resistances testing, able to detect resistance-associated substitutions in the viral sequence, is at present a matter of debate. Areas covered: The role of resistance associated substitutions is examined through the evaluation of the data from clinical trials that have assessed the impact of viral resistances on the treatment outcome...

BACKGROUND: Combination therapy with glecaprevir (GLE) and pibrentasvir (PIB) has high efficacy for pan-genotypic hepatitis C virus (HCV)-infected patients. However, the efficacy of the therapy for failures to prior direct-acting antiviral (DAA) regimens in real-world practice is not well known. METHODS: Thirty patients infected with HCV genotype 1b, 2a, 2b, or 3a who failed to respond during prior DAA therapies were treated with GLE/PIB for 12 weeks. HCV NS3 and NS5A drug resistance-associated variants (RAVs) were determined by direct sequencing...

According to the World Health Organization (WHO), 71 million people were living with Hepatitis C virus (HCV) infection worldwide in 2015. Each year, about 399,000 HCV-infected people succumb to cirrhosis, hepatocellular carcinoma, and liver failure. Therefore, screening of HCV infection with simple, rapid, but highly sensitive and specific methods can help to curb the global burden on HCV healthcare. Apart from the determination of viral load/viral clearance, the identification of specific HCV genotype is also critical for successful treatment of hepatitis C...
