Effects of Metformin, Pegylated Interferon Alpha and Ribavirin for Chronic Hepatitis C With Insulin Resistance

The aim of the study is to investigate the treatment response of metformin, Peg-IFN and ribavirin combination therapy for chronic hepatitis C virus (HCV).

Current standard of treatment for HCV with pegylated interferon(Peg-IFN)-alpha and ribavirin can achieve sustained virological response (SVR) in only 60-90% of patients. Insulin resistance is an important factor of non-response to combination therapy. Metformin is a insulin sensitizer and can effectively reduce insulin resistance. The aim of the study is to investigate the treatment response of metformin, Peg-IFN and ribavirin combination therapy for chronic HCV.
