Abstract

Major progress has been made in the treatment of chronic hepatitis C virus (HCV) infection over the 18 years since Hoofnagle et al. initially documented response of non-A non-B hepatitis to interferon alfa. Current optimal therapy with pegylated interferon alfa (PEG-IFN) and ribavirin results in sustained virologic response rates of just over 50%. With an estimated 2.7 million Americans with active HCV infection, we can anticipate a large number of potential treatment failures with the current standard of care. At this time, no therapy is approved by the US Food and Drug Administration for treatment failures of PEG-IFN and ribavirin. Maintenance interferon therapy with the goal of prevention of disease progression rather than viral eradication appears to offer an option for HCV treatment failures with advanced disease. Alternative medical strategies to reduce hepatic fibrosis are also under investigation. With the relatively static number of available organs for transplantation, prevention of disease progression and decompensation is essential for an impact to be made upon the predicted rates of HCV morbidity and mortality in the next 10 to 20 years.
