To explore the effect of intensive treatment for refractory chronic hepatitis C, and to improve the sustained viral response (SVR) rate of treatment with interferon plus ribavirin by optimizing therapeutic dose and course.Patients who did not acquire response or partial response by standard therapy (PEG-IFN alpha subcutaneous injection weekly plus Ribavirin 10.5 mg/kg) every day were enrolled and retreated with intensive treatment of 10 MU interferon every other day or 360 microg pegylated interferon alpha-2a weekly according to patients' wishes, and ribavirin 15 mg/kg every day. Serum HCV RNA was detected at baseline,treatment week 4, 12 and every 12 weeks succedent and 24 weeks after treatment end. Course of treatment was 72 to 96 weeks according to viral response. SVR was the mark of therapeutic effect.18 patients completed whole range therapy and follow-up, in which 12 patients acquired SVR, 5 patients treatment failure and 1 relapse. 3 patients acquired rapid viral response (RVR), and they all got complete Early Viral Response (cEVR) and SVR. RVR Patients' viral loads were significantly lower than that of patients who did not acquire RVR (t = 4. 687, P0.001). In 15 patients who did not acquire RVR, 8 patients acquired cEVR, and 9 acquired SVR. SVR rate of patients who were administered PEG-IFN alpha-2a was 4/5, 11 patients who acquired cEVR all acquired SVR, while in 7 patients who did not acquire cEVR, only 1 patient acquired SVR.High percent patients, who did not acquire response or partial response by previous standard antiviral therapy, could gain SVR by intensive dose interferon plus Ribavirin. In intensive treatment procedure, adjusting and prolonging course according to viral response after HCV RNA turned negative were important measures to improve refractory Chronic Hepatitis C SVR rate. |
