BACKGROUND Interferon-α in combination with ribavirin is the current gold standard for treatment of chronic hepatitis C. It is unknown if the development of autoimmune thyroid disease (TD) during treatment confers an improved chance of achieving sustained virologic response. The aim of this study is to assess the chance of achieving sustained virologic response (SVR) in patients who developed T...

OBJECTIVES To examine the safety and efficacy of ombitasvir and ABT-450 with ritonavir (ABT-450/r) ± ribavirin (RBV) in treatment-naïve, non-cirrhotic adults with chronic HCV genotype 1-3 infection. METHODS Patients in this open-label, exploratory, phase 2, multicenter study received ombitasvir (25 mg QD) and ABT-450/r (200/100 mg QD) ± RBV for 12 weeks. Primary efficacy endpoint was HCV RNA ...

Aim of antiviral therapy of patients with chronic hepatitis C is the sustained elimination of the hepatitis C virus (HCV). The standard of care (SOC) is peginterferon alfa-2a/-2b with ribavirin for 48 weeks or 24 weeks in patients infected with HCV genotype 1 or 2/3, respectively. Overall, approximately half of the patients can be cured by SOC. Based on baseline viral load and the speed of viro...

Recent advances in treatment of chronic hepatitis C virus have improved significantly due to the introduction of two new protease inhibitors-telaprevir and boceprevir. In combination with the previous standard of care, peginterferon and ribavirin, telaprevir and boceprevir have demonstrated improved sustained virologic response rates for HCV genotype 1 patients by approximately 30%. The purpose...

Up-regulation of programmed death-1 (PD-1) identifies exhausted T cells in various mouse and human viral models including chronic hepatitis C virus (HCV) infection, which is characterized by impaired CTL function. A large proportion of patients fail to eradicate HCV with current IFN-based antiviral therapy; in particular, African Americans are less likely to respond, but the mechanisms for thes...

We quantified antibody responses to the hepatitis C virus (HCV) proteome that are associated with sustained virologic response (SVR) in human immunodeficiency virus (HIV)/HCV-coinfected patients treated with pegylated interferon and ribavirin. Analysis of pre- and posttreatment samples revealed significant decreases in the combined anti-core, anti-E1, and anti-NS4 HCV antibody titers in those w...

The treatment of hepatitis C has evolved rapidly since the identification of the hepatitis C virus (HCV) in 1989. Since the first accepted therapy for HCV infection, recombinant interferon, received marketing approval a little more than a decade ago, it has come to be used in combination with ribavirin for improved rates of sustained virologic response. Recently, pegylated versions of interfero...

INTRODUCTION The success of the antiviral treatment in patients with chronic hepatitis C depends on the factors related to the virus and the host. The aim of the study is the analysis of the antiviral therapy which is a combination of pegylated interferon and ribavirin, considering various factors that will identify the predictors of the sustained virological response. MATERIAL AND METHODS Th...
