To determine how various factors influence the response to interferon (IFN) therapy, we retrospectively studied 157 consecutive Japanese patients with chronic hepatitis C who received various treatment schedules of IFN. They were divided into two groups on the bases of outcome. One group was comprised of 65 patients who achieved a sustained normalization of serum alanine aminotransferase (ALT) levels for at least 6 months after treatment, while the other group was comprised of 84 patients with persistent elevation of serum ALT levels, despite treatment. Genotyping of hepatitis C virus (HCV) was done by polymerase chain reaction (PCR) with genotype specific primers, analysing the variations in nucleotide sequence within the NS 5 region of the HCV genome, namely genotypes PT, K1, K2a and K2b. We then used a multivariate analysis to determine the factors related to mode of treatment, patient characteristics and HCV genotype in relation to the response to IFN therapy. Of the 16 factors analysed, the HCV genotype (genotype K2a or K2b, P < 0.0008), treatment schedule (intermittent administration following a daily schedule, designated as combined schedule, P > 0.0014) and liver histology just before treatment (chronic persistent hepatitis or mild chronic aggressive hepatitis, P < 0.0324) were the most strongly correlated with a normalizing response to IFN therapy. These results suggest that not only are the IFN treatment schedule and patient profile significant, but the properties of the virus also influences the response. However, as the IFN treatment schedule is the only changeable factor, it should be designed to maximize the benefit of IFN therapy.
