title: Treatment of hepatitis C: impact on the virus, quality of life and the natural history.
abstract: Results of treatment for chronic hepatitis C have improved substantially during the last decade. Combination treatment with interferon alpha 3 MU tiw and ribavirin 1000-1200 mg daily during 24 to 48 weeks leads to sustained virologic response (SVR) in approximately 40% of patients, two to three times more than interferon alpha monotherapy. It was considered standard therapy at the EASL Consensus Conference of February 1999. Recently, results have been published on treatment with pegylated interferons alone and in combination with ribavirin. Pegylated interferon treatment leads to almost doubling of SVR rate as compared with standard interferon monotherapy. Combination of pegylated interferon alpha with ribavirin is most promising, leading to a SVR rate of 54 to 56%. It is to be expected that this treatment will become the new standard. Selected patients with geno-type 2 or 3 have now a SVR rate of almost 80%. Response to treatment also leads to significant improvement of quality of life and survival, probably by reducing the risk of developing hepatocellular carcinoma. Recent data suggest that early interferon alpha treatment of patients with acute hepatitis C largely prevents the development of chronicity.
