【Abstract】 Objective The randomized study was conducted to determine the safety and efficacy of consensus interferon (CIFN) in the treatment of chronic hepatitis C at two doses compared with that of interferon alfa 2a (IFN α 2a). Methods 187 patients were randomized to receive CIFN 15 μg, CIFN 9 μg or 3 MU interferon α 2a. Patients received subcutaneous injections tiw for 24 weeks followed by 24 weeks of observation. Normalization rate of serum alanine aminotransferase (ALT) and seroconversion rate of HCV RNA by (RT PCR) were detected to evaluate the efficacy. The categories and severity of adverse events were registered. Results 180 patients completed full course of treatment, 56 cases of which were treated with CIFN 15 μg,63 cases with CIFN 9 μg and 61 cases with 3MU IFN α 2a, respectively. After 24 weeks treatment, ALT normalization rate for 15 μg CIFN, 9 μg and 3MU IFN α 2a were 76.9%, 68.3% and 57.4%. HCV RNA seroconversion rate were 89.6%, 73.6% and 60.4%. There were significant statistical difference of both ALT normalization rate and HCV RNA seroconversion rate between CIFN 15 μg and IFN α 2a 3MU treated patients ( P <0.05 and P <0.01). After 48 weeks therapy, ALT normalization rate for those three groups were 78.8%, 63.9% and 55.0%, the HCV RNA seroconversion rate were 75.0%, 65.4% and 54.7%. It also showed significant statistical difference between CIFN 15 μg and 3MU IFN α 2a group ( P <0.01 and P <0.05). The short term and long term complete response rate in the patients treated with CIFN 15 μg (70.8% and 64.6%, respectively) were higher than in the patients treated with IFN α 2a 3 MU (34.0% and 43.4%, respectively; P <0.01 and P <0.05). The category, incidence and severity of adverse events were similar in 3 groups. Conclusion CIFN is safe and effective at both 9 μg and 15 μg doses in the treatment of chronic hepatitis C. Futhermore, the results suggest the short term as well as long term efficacy of 15 μg to be more effective than IFN α 2a (3 MU) without increasing toxicity.更多还原
