Estimation of liver fibrosis by noncommercial serum markers in comparison with transient elastography in patients with chronic hepatitis C virus infection receiving direct-acting antiviral treatment.

Treatment decisions are based on extent of fibrosis in patients with chronic hepatitis C (HCV) infection. Noninvasive diagnostic tools may help to avoid liver biopsy. We investigated the diagnostic accuracy of noncommercial serum scores in comparison with transient elastography (TE).

Treatment of hepatitis C genotype 1 infection in Germany: effectiveness and safety of antiviral treatment in a real-world setting.

Background: In pivotal studies with direct-acting antivirals (DAAs), rates of sustained virological response in hepatitis C genotype 1 infection are >90%.

Objective: The objective of this article is to assess real-world safety and effectiveness of DAA treatment in a prospective multicenter registry study.

Methods: The German Hepatitis C-Registry includes 6606 patients with genotype 1 from 246 centers, treated between February 2014 and June 2016 at the discretion of the physician.

Long-term outcome of chronic hepatitis C virus infection in a real-world setting: The German LOTOS study.

Background & Aims: There are few large-scale, prospective studies comparing liver-associated events in treated and untreated patients with CHC managed in routine clinical practice.

Methods: Patients with CHC were prospectively enrolled in a non-interventional study. Data from patients with available documentation who had either achieved a sustained virological response, or were non-responders, relapsers, or had virological breakthrough following treatment with peginterferon alfa-2a±ribavirin, or who had been diagnosed but never treated at least 3 years previously, and who remained under medical observation were analyzed.

Real-world use, effectiveness and safety of anti-viral treatment in chronic hepatitis C genotype 3 infection.

Background: Treatment of chronic hepatitis C genotype 3 (GT3) is more challenging compared with other genotypes. Since 2014, several new treatment regimens have been approved but sometimes based on limited data.

Aim: To validate the use, effectiveness and safety of anti-viral treatment in chronic hepatitis C genotype 3 infection under real-word conditions.

Outcomes and Costs of Treating Hepatitis C Patients in the Era of First Generation Protease Inhibitors - Results from the PAN Study.

1 Objective: Chronic hepatitis C virus infections (HCV) cause a significant public health burden. Introduction of telaprevir (TVR) and boceprevir (BOC) has increased sustained virologic response rates (SVR) in genotype 1 patients but were accompanied by higher treatment costs and more side effects. Aim of the study was to assess outcomes and costs of treating HCV with TVR or BOC in routine care.

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 And 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.

Costs and outcomes of treating chronic hepatitis C patients in routine care - results from a nationwide multicenter trial.

Viral hepatitis is a major public health problem affecting millions of people worldwide. Long-term consequences are the development of liver cirrhosis and hepatocellular carcinoma. The aim of the study was to assess outcomes and costs of treating patients with chronic hepatitis C in clinical practice in Germany.

Benefit of Treatment Individualization in Patients with Chronic Hepatitis C Receiving Peginterferon Alfa-2a and Ribavirin in a Large Noninterventional Cohort Study.

Background And Aims: Individualization of treatment with peginterferon alfa and ribavirin in patients with chronic hepatitis C showed benefit in controlled trials and was implemented in treatment guidelines to increase response rates and to reduce side effects and costs. However, it is unknown whether individualization was adopted in routine daily practice and whether it translated into improved outcomes.

Methods: From a large noninterventional cohort study, clinical and virologic response data of 10,262 HCV patients who received peginterferon alfa-2a and ribavirin between 2003-2007 and 2008-2011 were analyzed.

Real-life experience with first generation HCV protease inhibitor therapy in Germany: The prospective, non-interventional PAN cohort.

Background And Aims: The efficacy and safety of peginterferon alfa-2a (PEG-IFN) plus ribavirin (RBV) and either boceprevir (BOC) or telaprevir (TVR), and physician adherence to treatment algorithms were evaluated in patients included in an ongoing non-interventional study (PAN) enrolling adults with chronic hepatitis C virus (HCV) infection managed in German office-based practices.

Methods: The analysis included HCV genotype 1-infected, treatment-naïve and treatment-experienced patients treated with BOC or TVR. Demographic, treatment history, virological response, safety, and patient management data were collected.

Age-related differences in response to peginterferon alfa-2a/ribavirin in patients with chronic hepatitis C infection.

Aim: To evaluate the safety and efficacy of pegylated interferon alfa-2a and ribavirin therapy in elderly patients with chronic hepatitis C infection.

Methods: Patients characteristics, treatment results and safety profiles of 4859 patients with hepatitis c virus (HCV) infection receiving treatment with pegylated interferon alfa-2a and ribavirin were retrieved from a large ongoing German multicentre non-interventional study. Recommended treatment duration was 24 wk for GT 2 and GT 3 infection and 48 wk for GT 1 and GT 4 infection.

Screening for autoantibodies in chronic hepatitis C patients has no effect on treatment initiation or outcome.

Autoantibodies in hepatitis C virus-infected patients may indicate autoimmune hepatitis or other immune-mediated diseases. This may impact safety and efficacy of interferon-based therapy of chronic hepatitis C. We investigated the association between a positive test result for a variety of autoantibodies and the initiation and efficacy of therapy for chronic hepatitis C.

Treatment results of chronic hepatitis C genotype 5 and 6 infections in Germany.

Chronic hepatitis C due to HCV genotype 5 and 6 infection is infrequently reported and patients are usually not included in trials. As boceprevir and telaprevir are not approved for these genotypes, pegylated interferon plus ribavirin will remain the treatment of choice for the coming years. Patients infected with HCV genotype 5 or 6 were identified by data base search from an ongoing observational cohort study in Germany.
