Abstract

The response to the treatment with pegylated interferon (PEG IFN)-α combined with ribavirin in chronic hepatitis C virus (HCV) infection varies with some patients having a rapid or early response which is not sustained. To investigate the rates of rapid virological response (RVR), early virological response (EVR) and sustained virological response (SVR) in an Irish cohort of HCV infected patients receiving IFN-α/ribavirin. Rates of RVR, EVR and SVR were examined in 123 patients undergoing standard treatment for chronic HCV infection between 2001 and 2007 at a Dublin Teaching Hospital. The rates of RVR, EVR and SVR in genotype 1 patients were 48, 68 and 50%, while in genotype 2/3 patients they were 87, 93 and 87%, respectively. The positive predictive values (PPV) of RVR for SVR in genotype 1 and genotype 2/3 patients were 90 and 92.4%, respectively. The rates of response to PEG IFN-α/ribavirin in Irish patients are consistent with other international reports. We support the regular monitoring of rapid and early virological response as a standard of care in treating chronic hepatitis C patients.
