Brief Summary

It is estimated that 350-400 million people have chronic infection with hepatitis B virus (HBV) all over the world. In china, 93 million individuals suffer from this chronic condition. Currently, seven medications are approved for the treatment of hepatitis B: two formulations of interferon and four nucleos(t)ide analogues. The Chinese population has one of the longer average life spans, and the size of the aged population has been increasing rapidly. As a result, the prevalence of elderly patients with HBV has increased, and the potential for development of cirrhosis or hepatocellular carcinoma in such patients is real. Hence, treatment of elderly patients with HBV is an important issue. However, ADV or ETV has become first choice due to the more side effect of INF and the resistant of LAM and LdT. But treatment outcomes with ADV and ETV in elderly are not known yet. In this study, we will evaluate and compare the efficacy and tolerability of ADV and ETV between younger and older patients with HBV. The aims of the present study are (1)to assess the benefits of ADV or ETV therapy for elderly patients with chronic hepatitis B, and (2)to determine differences in the emergence rate of side effect.

Sampling MethodProbability Sample
Study Population

We retrospectively analyzed a consecutive cohort of chronic hepatitis B patients treated with ADV, 10mg, daily, or with ETV,0.5mg,daily between January 2010 and December 2013 in a single tererral referral hospital in Beijing. Data were retrieved from a prospectively maintined database.

You may qualify if:

  • Age≥18 years
  • HBsAg positive for more than 6 months before enrollment
  • Serum HBVDNA \>2×104IU/ml and serum ALT \>80U/L or TBIL \< 34 umol/L for chronic hepatitis B
  • Serum ALT \< 80U/L, but hepatic inflammation scores ≥ G2 or hepatic fibrosis stage ≥ S2 for chronic hepatitis B
  • Serum HBVDNA \>40 IU/ml for cirrhosis regardless of ALT and TBIL

You may not qualify if:

  • Co-infected with HCV, HDV or HIV, or autoimmune liver diseases combined
  • received antiviral therapy or immunosuppressant drugs before 6 months prior to enrollment
  • Renal function: creatinine \>1.5 ULN or eGFR\< 50ml/min/1.73m2 before therapy
  • Combined with hepatocarcinoma before therapy
  • suspend therapy voluntarily
  • use other nephrotoxic drugs
