Chinese herbal medicine and interferon in the treatment of chronic hepatitisB: a meta-analysis of randomized, controlled trials

This meta-analysis was conducted to examine the effectiveness of Chinese herbal medicine (either alone or with interferon alfa) in treating chronic hepatitis B. The TCMLARS, AMED, CISCOM, EMBASE, MEDLINE, and Cochrane Collaboration databases were searched and then hand-searched the articles' bibliographies. Chinese herbal medicine significantly increased seroreversion of HBsAg and was equivalent to interferon alfa in seroreversion of HBeAg and hepatitis B virus (HBV) DNA; Chinese herbal medicine combined with interferon alfa significantly increased seroreversion of HBsAg, HBeAg, and HBV DNA. The Chinese herbal medicine active component bufotoxin combined with interferon alfa significantly increased HBeAg and HBV DNA seroreversion. The Chinese herbal medicine active component kurorinone was equivalent to interferon alfa in seroreversion of HBeAg and HBV DNA. Although the quality of existing studies was poor, these data suggest that further trials of Chinese Herbal Medicine and interferon in chronic hepatitis B infection are justified.
