title: [A trial of new interferon therapy for the patients with chronic hepatitis C resistant to interferon therapy].
abstract: HCV-RNA clearance rates are reported to be about 30-40% of the patients treated with IFN for less than 6 months. But IFN therapy is ineffective for chronic hepatitis C patients with HCV-genotype 1b and a high virus load. We evaluated the efficacy of different IFN therapy compared with standard IFN therapy for chronic hepatitis C patients resistant to interferon therapy. That is, we assessed the following therapy; 1) prolonged IFN therapy, 2) IFN-beta therapy of twice a day, 3) IFN-beta therapy daily for 24 weeks, 4) combination therapy of IFN-alpha and IFN-beta. In some cases, these IFN therapies were effective than a standard IFN therapy.
