Influence of Antiviral Treatment to the Long-Term Prognosis of Patients With Chronic HBV Infection - Full Text View

Purpose

Influence of antiviral treatment to the long term prognosis of patients with chronic HBV infection. The aim of antiviral treatment for HBV is to reduce the long term severe complications. In this study, the investigators divided patients with chronic HBV infection into two groups, which start early antiviral treatment and conventional antiviral treatment respectively. All the patients will be followed for ten years. From this study, the investigators want to find out the optimal time for patients with chronic HBV infection to start antiviral treatment.

Drug: lamivudine 100mg, P.O.,QD, duration: until HBeAg seroconversion for more than 2years. Drug: Telbivudine 600mg, P.O.,QD, duration: until HBeAg seroconversion for more than 2years. Drug: Enticavir 0.5mg, P.O.,QD, duration: until HBeAg seroconversion for more than 2 years. Drug: Adefovir Dipivoxil Tablets 10mg, P.O.,QD, duration: until HBeAg seroconversion for more than 2years.
Active Comparator: B 120 subjects (have family history of hepatic carcinoma or liver cirrhosis). Antiviral treatment are started when ALT is higher than 80u/L (regular antiviral treatment).	Drug: lamivudine 100mg, P.O.,QD, duration: until HBeAg seroconversion for more than 2years. Drug: Telbivudine 600mg, P.O.,QD, duration: until HBeAg seroconversion for more than 2years. Drug: Enticavir 0.5mg, P.O.,QD, duration: until HBeAg seroconversion for more than 2 years. Drug: Adefovir Dipivoxil Tablets 10mg, P.O.,QD, duration: until HBeAg seroconversion for more than 2years.
Experimental: C 180 subjects (have no family history of hepatic carcinoma or liver cirrhosis). Antiviral treatment are started when ALT is lower than 80u/L (early antiviral treatment).
