Sustained Viral Response and Clincal Relapse in Chronic Hepatitis B Patients Who Achieved HBeAg Seroncongversion by Interferon Therapy
Sustained Viral Response and Clincal Relapse in Chronic Hepatitis B Patients Who Achieved HBeAg Seroncongversion by Interferon Therapy
Chronic hepatitis B (CHB) is a serious liver disease worldwide, and the leading cause of cirrhosis and hepatocellular carcinoma (HCC). HBeAg seroconversion is considered to be the satisfied endpoint of antiviral therapy in HBeAg-positive chronic hepatitis B patients. However, HBV reaction, even reverse back to HBeAg positive and clinical relapse could occur in some patients who achieved HBeAg seronconversion by interferon treatment. In this study, the long-term efficacy of interferon therapy in HBeAg positive patients achieved HBeAg seronconversion after interferon treatment and the factors associated with viral and clinical relapse will be observed.
HBeAg positive chronic hepatitis B patients achieved HBeAg seronconversion by interferon treatment will be enrolled and observed for 156 weeks. Serum HBV DNA, HBsAg, anti-HBs, HBeAg, and anti-HBe will be measured every 3 months during the observation period, liver function tests were performed every 3 months also. The liver ultrasonic examination would be taken every 3-6 months. The primary endpoint is sustained viral response, and secondary endpoints is HBV DNA reaction and clinical relapse defined as virla relapse with abnormal ALT during observation period.
