Brief Summary

The host immunity has been generally recognized as the main factors to determine the outcome of chronic hepatitis B virus (HBV) infection; however, previous studies have shown that HBV-specific T cell and B cell function are exhausted in chronic hepatitis B (CHB) patients. Recently, It is suggested that hepatitis B surface antigen (HBsAg) may play a key role in the immune tolerance or immune exhaustion. Anti-HBV immune responses are partially recovered when patients achieved hepatitis B e antigen (HBeAg) seroconversion during antiviral therapy, and can be nearly recovered during HBsAg seroconversion. However, it is still difficult to achieve the ideal terminal, HBsAg seroconversion. For this reason, immunotherapy would be helpful to enhance the anti-HBV immunity and acquire higher HBsAg seroconversion. Here, the investigators propose a hypothesis that hepatitis B immune globin (HBIG)+granulocyte-macrophage colony-stimulating factor (GM-CSF)+HBV vaccine can enhance anti-HBV immune responses and improve HBsAg seroconversion in CHB patients who has achieved HBeAg seroconversion using nucleoside analogues treatment.

Drug treatment

EXPERIMENTAL

Drug: Given four times in week 0, 4, 12 and 24. At each time of treatment, the patients will be hospitalized and treated with 800 unit of HBIG intramuscularly at day 0, 1, 2, 3 and 4, then were treated with 75 μg of GM-CSF subcutaneously at day 2, 3, 4, 5 and 6, and finally were injected 20μg of HBV vaccine subcutaneously at day 6.

Drug: Drug

GM-CSF control

OTHER
