Brief Summary

Studies have shown that the HBeAg seroconversion rate of HBeAg positive chronic hepatitis B with tenofovir for one year's treatment was 17.8% and the negative conversion rate of their HBeAg and HBV DNA were 20.0% and 97.6%. The HBeAg Seroconversion rate of these patients was lower.Clinically, most patients need to take tenofovir for a long time, which may cause serious complications such as renal function damage,with decreased therapy compliance and Increased cost of treatment.In the course of tenofovir treatment, it is common that HBV-DNA negative patients with HBeAg Being down poor or staying at a low positive level for a long time keep taking the medicine. Therefore, it is Significant to Increase the HBeAg seroconversion rate of tenofovir during the clinical treatment. Telbivudine has a strong antiviral effect.Studies have shown that the HBeAg seroconversion rate of HBeAg positive CHB for one year was 25%, which was higher than other nucleosides, and it could also improve the damaged renal function to a certain extent.The HBeAg seroconversion rate of patients with poor response to tenofovir for 12 months could be still poor if for 24 months . Therefore, this study is to observe the efficacy of these patients combined with telbivudine.
