The curative effect of adefovir dipivoxil treating HBeAg negative chronic hepatitis B and treating HBeAg positive chronic hepatitis B combining interferon α-2b.

This study aimed to research the efficiency of adefovir dipivoxil in hepatitis B e antigen (HBeAg)-negative chronic hepatitis B treatment and in combination with α-2b interferon in the treatment of HBeAg-positive chronic hepatitis B. A total of 102 cases of adult patients with HBeAg chronic hepatitis B were selected for testing. HBeAg negative chronic hepatitis B patients took 10mg adefovir dipivoxil capsules once daily, while positive chronic hepatitis B patients were randomly divided into either a treatment group or a control group. The treatment group was administrated with 10mg adefovir dipivoxil capsules, 1 time daily, and injected with 5 million U Recombinant Human Interferon α-2b through muscle every other day. The control group was treated with 10mg adefovir dipivoxil capsules, 1 time per day. We examined alanine aminotransferase (ALT) normalization and the Hepatitis B Virus (HBV)-DNA negative rate (undetectable rate), as well as, HBeAg / hepatitis B e antibody (HBeAb) sero-conversion rate to detect treatment effects. The results proved that after 6 months of medication therapy, the ALT normalization rate was 49.9% and the HBV-DNA negative conversion rate was 54.3%. 18 months into the treatment, showed an ALT normalization rate of 73.2%, while the HBV-DNA negative conversion rate grew to 76.8%. The use of adefovir dipivoxil treatment of the negative chronic HBV has a certain extent combined with α-2b Interferon therapy in treatment of HbeAg positive chronic hepatitis B. After a 48-week observation period, ALT normalization and HBV-DNA rate could not be measured, HBeAg/HBeAb sero-conversion rose higher, indicating that the treatment of the combined drugs is more efficient than taking adefovir dipivoxil by itself, and the data were comparable with the control group (P<0.05). Thus adefovir dipivoxil can greatly improve the restrain function to HBV-DNA and improve the immunity and control ability of the body, with obvious short-term effects, in combination with Interferon.
