Primary Outcome Measures:
  • Proportion of patients with HIV RNA below LDL and HBV DNA below 2.3log10 copies/ml at week 48 [ Time Frame: one year ] [ Designated as safety issue: No ]
    HIV and HBV viral load decreases in patients taking the regimen

Secondary Outcome Measures:
  • Incidence of targeted adverse events over 48 weeks [ Time Frame: week 12,24,48 ] [ Designated as safety issue: Yes ]
    Clinical and laboratory safety(liver, renal, hematologic)of TDF+3TC+EFV for HIV/HBV co-infected patients

Other Outcome Measures:
  • CD4+ cell count increase at week 48 [ Time Frame: one year ] [ Designated as safety issue: No ]
    CD4+ cell count increases in patients receving the regimen

TDF+3TC+EFV treatment regimen in Adults with HIV/HBV Coinfection
Drug: Regimen:TDF+3TC+EFV
TDF+3TC+EFV for HIV/HBV co-infection

Detailed Description:

HIV/HBV co-infections are frequently observed due to shared routes of transmission. TDF and 3TC are nucleotide analogues that can inhibit both HIV and HBV DNA polymerases. There is higher risk to cause drug resistance in treating HBV or HIV infection with 3TC or TDF monotherapy than combination trerapy. Combination tharapy could decreases drug resistance. China's HIV epidemic remains one of low prevalence overall, but with pockets of high infection among specific sub-populations and in some localities. China has a very high endemicity for hepatitis B too. A substantial proportion of HIV-infected individuals are co-infected with HBV. TDF + 3TC + EFV will be a common regimen for HIV/HBV co-infected Chinese individuals.

The purpose of this study of this study is to determine whether TDF will be safe for patients with HIV and HBV co-infection and the combination of TDF+3TC+EFV will suppress HIV and HBV viral load below LDL at week 48 of treatment in patients with HIV and HBV co-infeciton.This study will enroll 100 adult subjects and follow these patients for 48 weekes.There will be one enrollment visit(baseline) and visits at 2,4,8,12,24,36,48 weeks after initiation of the study regimen.
