Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The most important method to slow down and stop the liver disease progression in patients with chronic hepatitis B is antiviral therapy, by which to achieve maintaining viral response during treatment or obtain sustained viral response after treatment. The aim of the therapy with interferon is make patients obtain immune control to HBV, in clinical practice, it was expressed as HBeAg seroconversion, HBsAg loss and sustained viral response in HBeAg positive patients. However, those targets can't be get in most patients by 48 weeks of interferon treatment, and some patients need extended treatment to enhance the rate of HBeAg seroconversion and HBsAg loss. In this cohort study, the efficacies of extended therapy of interferon in HBeAg positive chronic hepatitis B patients will be evaluated.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this cohort study, the HBeAg positive chronic hepatitis B patients would be treated with peginterferon alpha 2a(PEG-IFN a-2a) for 96 week and followed 24 weeks after treatment. Serum HBV DNA load, HBsAg/anti-HBs level, HBeAg/anti-HBe will be tested at enrollment and every 3 months during treatment and follow period. Parameters of liver and kidney function, and liver ultrasound examination will be tested with intervals 1-3 months. The rates of HBeAg seroconversion, HBsAg loss, and sustained viral response will be evaluated after treatment and follow up.
