Pretreatment virus load and multiple amino acid substitutions in the interferon sensitivity–determining region predict the outcome of interferon treatment in patients with chronic genotype 1b hepatitis C virus infection
K Chayama, A Tsubota, M Kobayashi, K Okamoto, M Hashimoto, Y Miyano, H Koike, M Kobayashi, I Koida, Y Arase, S Saitoh, Y Suzuki, N Murashima, K Ikeda, H Kumada – 30 December 2003 – Hepatitis C virus (HCV) genotype 1b and high pretreatment virus load are predictive factors of poor response to interferon therapy in patients with chronic hepatitis C. To further examine the factors predicting the response to interferon in patients with genotype 1b infection, we analyzed 110 consecutive patients with HCV who were treated with a total of 624 million units of lymphoblastoid interferon alfa.
