Treatment outcomes in hepatitis C virus genotype 1a infected patients with and without baseline NS5A resistance‐associated substitutions
Background&aims The presence of baseline resistance-associated substitutions (RASs) reduced sustained virologic response (SVR) rates in chronic hepatitis C virus (HCV) genotype 1a infected patients treated with Elbasvir/Grazoprevir (EBR/GZR). This study aimed to evaluate the frequency of NS5A RASs and treatment outcomes in patients for whom EBR/GZR was intended. Methods We sequenced NS5A in 832 samples from German genotype1a-infected DAA-naive patients population-based, which were collected in the European Resistance Database. Treatment outcomes and clinical parameters were evaluated in 519 of these patients retrospectively. Results Overall, 6.5% of patients harbored EBR-specific NS5A RASs …
Clinical significance of detectable and quantifiable HCV RNA at the end of treatment with ledipasvir/sofosbuvir in GT1 patients
Background & aims AASLD/IDSA treatment guidelines for hepatitis C virus (HCV) infection state that testing for quantitative HCV RNA can be considered at the end of antiviral treatment (EOT) with interferon-free regimens. However, it remains unclear how to respond to a detectable or even quantifiable HCV RNA result. The aim of this study was to analyse the frequency and predictive value of detectable and quantifiable HCV RNA results at the EOT in patients with HCV genotype 1 infection treated with ledipasvir (LDV) and sofosbuvir (SOF) ± ribavirin (RBV) in a large real-world cohort. Methods A retrospective analysis of the DHC-R (Deutsches Hepatitis C-Register, German Hepatitis C-Registry) coh…
Effects of Smoking on Pegylated Interferon alpha 2a and First Generation Protease Inhibitor-based Antiviral Therapy in Naïve Patients Infected with Hepatitis C Virus Genotype 1.

 
 
 
 
 
 Background & Aims: Smoking has multiple effects on factors influencing hepatitis C and antiviral therapy, including lipid metabolism, fibrosis, platelet count and adherence aspects. The aim of this analysis was to determine the impact of smoking on hepatitis C virus antiviral therapy.
 Methods: Data of two cohorts of an observational multicenter study including therapy-naïve patients infected with genotype 1 hepatitis C virus (HCV) treated with dual antiviral therapy (n=7,796) with pegylated interferon alpha 2a in combination with ribavirin, or triple antiviral therapy (n=1,122) containing telaprevir or boceprevir, were analysed.

Alcohol and Cannabis Consumption Does Not Diminish Cure Rates in a Real-World Cohort of Chronic Hepatitis C Virus Infected Patients on Opioid Substitution Therapy-Data From the German Hepatitis C-Registry (DHC-R).
Background: The importance of alcohol and cannabis consumption for the effectiveness of treatment of chronic hepatitis C virus (HCV) infection with direct acting antivirals (DAAs) in people on opioid substitution therapy (OST) has not been investigated in detail. Methods: We investigated sustained virological response (SVR) rates and proportion of lost to follow-up (LTFU) between OST (n = 739) and non-OST patients (n = 7008) in the German Hepatitis C-Registry (Deutsches Hepatitis C-Register, DHC-R), which is a national multicenter prospective non-interventional real-world registry. Non-OST patients comprised patients with former/current drug use (non-OST/DU; n = 1500) and patients never con…
Evolution of HCV patient characteristics and DAA regimens in the German Hepatitis C Registry (DHC-R) in 2014 and 2015
The urgent need in HCV-infected patients with liver disease mandated the rapid implementation of IFN-free DAA combination therapies following their regulatory approval in 2014 and 2015 without full knowledge of the optimal combinations and regimens. Investigating the evolution of the DAA utilization patterns and treatment outcomes could provide learnings for future situations. This was an analysis of a prospective observational database from the German Hepatitis C Registry (DHC-R) covering a period from May 2014 to September 2015. Adult patients had evidence of chronic HCV GT1 or GT4 infection and were treated with an IFN-free combination regimen of simeprevir (SMV) + sofosbuvir (SOF) or o…
Real-world experience with the all-oral, interferon-free regimen of ombitasvir/paritaprevir/ritonavir and dasabuvir for the treatment of chronic hepatitis C virus infection in the German Hepatitis C Registry.
Summary Real-world studies are relevant to complement clinical trials on novel antiviral therapies against chronic hepatitis C; however, clinical practice data are currently limited. This study investigated effectiveness and safety of ombitasvir/paritaprevir/ritonavir (OBV/PTV/r)±dasabuvir (DSV)±ribavirin (RBV) for treatment of HCV genotype (GT) 1 and GT4 infection in a large real-world cohort. The German Hepatitis C Registry is an observational cohort study prospectively collecting clinical practice data on direct-acting antiviral therapies. Patients with GT1/4 infection treated with OBV/PTV/r±DSV±RBV were analysed. Effectiveness was assessed by sustained virologic response in 558 patients…
Predictive factors for sustained virological response after treatment with pegylated interferon α-2a and ribavirin in patients infected with HCV genotypes 2 and 3.
BackgroundPrevious trials have often defined genotype 2 and 3 patients as an "easy to treat" group and guidelines recommend similar management.AimsThe present study looks for differences between the two genotypes and analyzes predictive factors for SVR.MethodsProspective, community-based cohort study involving 421 physicians throughout Germany. The analysis includes 2,347 patients with untreated chronic HCV genotype 2 (n = 391) and 3 (n = 1,956) infection treated with PEG-IFN α-2a plus ribavirin between August 2007 and July 2012.ResultsWhen compared with genotype 2 patients, those with genotype 3 were younger, had a shorter duration of infection, lower values of total cholesterol, LDL chole…

Direct-acting antiviral treatment of chronic HCV-infected patients on opioid substitution therapy: Still a concern in clinical practice?
BACKGROUND AND AIMS There is limited real-world information on the effectiveness of antiviral treatment of chronic hepatitis C virus (HCV) infection with direct-acting antivirals (DAA) in people on opioid substitution therapy (OST). This study compared sustained virological response (SVR) rates and proportion of lost to follow-up (LTFU) between OST and non-OST patients in the German Hepatitis C-Registry (DHC-R). DESIGN National multi-centre prospective real-world registry (German Hepatitis C-Registry, DHC-R). Non-OST patients comprised patients with former/current drug use (non-OST/DU) and patients never consuming drugs (non-OST/NDU). SETTING A total of 254 medical centres in Germany, inclu…
