Metformin improves sustained virologic response in difficult-to-cure hepatitis C: More questions than answers

Sustained virologic response to antiviral therapy for chronic hepatitis C virus infection: a cure and so much more.

Sustained virologic response (SVR) is defined as aviremia 24 weeks after completion of antiviral therapy for chronic hepatitis C virus (HCV) infection. In analyses of SVR durability, the incidence of late relapse is extremely low (<1%). Histologic regression of both necroinflammation and fibrosis has been demonstrated in paired liver biopsy samples in SVR-achieving patients. More noteworthy is ...

optimizing treatment with pegylated interferon-ribavirin of genotype 3 chronic hepatitis c: more questions than answers

The placebo response in clinical trials: more questions than answers.

Meta-analyses and re-analyses of trial data have not been able to answer some of the essential questions that would allow prediction of placebo responses in clinical trials. We will confront these questions with current empirical evidence. The most important question asks whether the placebo response rates in the drug arm and in the placebo arm are equal. This 'additive model' is a general assu...

Sustained virologic response among Latino veterans; does it represent the cure of chronic hepatitis C infection?

OBJECTIVE Short-term benefits of achieving sustained virologic response (SVR) to treatment for hepatitis C virus infection (HCV) have been well established. However long-term data on benefits of achieving SVR has just begun to emerge. The purpose of this study was to determine whether SVR truly represents long- term viral eradication in a Latino veteran population and document clinical and bioc...

Durability of Sustained Virologic Response in Chronic Hepatitis C

BACKGROUND/AIMS The aim of this study is to investigate the rate of sustained virologic response (SVR) in chronic hepatitis C patients receiving antiviral treatment. METHODS The files of patients with chronic hepatitis C treated with interferon±ribavirin between 1995 and 2009 were reviewed retrospectively. Six months after the end of treatment, patients with negative hepatitis C virus (HCV)-R...
