Treatment of Chronic Hepatitis C Virus Infection

Abstract

OBJECTIVE: To review the literature on the treatment of chronic hepatitis C virus (HCV) infection. DATA SOURCES: MEDLINE search (1986–December 1999) using key words such as HCV, hepatitis, non-A and non-B hepatitis, as well as terms regarding treatment during that time period. DATA SYNTHESIS: HCV infection was initially treated with interferon monotherapy, but only a minority of patients responded to long-term therapy. A higher rate of response in both interferon-naïve patients and interferon-relapsers has been achieved by using the combination of interferon and ribavarin. Other treatment regimens including high-dose interferon protocols, ursodeoxycholic acid, amantadine, and nonsteroidal antiinflammatory drugs have been less promising. Many alternative therapies are being investigated. CONCLUSIONS: HCV infection is a major public health problem. It is now possible to achieve a cure in nearly 50% of the patients with this infection. Many additional therapies are being evaluated in order to achieve a higher cure rate.
