Gotaro Yamada, Masahiro Takatani, Fumitoshi Kishi, Michiko Takahashi, Toshihiko Doi, Takao Tsuji, Sadahito Shin, Masashi Tanno, Mickey S. Urdea, Janice A. Kolberg – 1 November 1995 – To clarify the viral factors that may predict the therapeutic effect of interferon (IFN) in chronic hepatitis C (CHC) patients, we investigated the quantitative serum hepatitis C virus (HCV) RNA level, genotype, and liver biopsy histological features in 60 patients who were treated with 360 × 106 U of natural IFN‐α for 36 to 48 weeks and for more than 12 months after therapy.
