  Purpose

The purposes of this study include 1) to compare the seroconversion rate of an intensive standard-dose regimen (0, 1, 2 and 6 months) to a standard-dose regimen (0,1 and 6 months), and 2) to compare the seroconversion rate of an intensive double-dose regimen (40 μg at 0,1,2 and 6 months) to a standard-dose regimen (20 μg at 0,1 and 6 months) of HBV vaccine in HIV-infected adult patients.

Primary Outcome Measures:
  • Seroconversion rate (percentage of subjects with anti-HBs antibody titer >= 10 IU/L) at day 210 [ Time Frame: Day 210 ] [ Designated as safety issue: No ]
    1. To compare the seroconversion rate at day 210 of an intensive standard-dose regimen (0, 1, 2 and 6 months) to a standard-dose regimen (0,1 and 6 months)
    2. To compare the seroconversion rate at day 210 of an intensive double-dose regimen (40 μg at 0,1,2 and 6 months) to a standard-dose regimen (20 μg at 0,1 and 6 months) of HBV vaccine in HIV-infected adult patients


Secondary Outcome Measures:
  • Seroprotective rate (percentage of subjects with anti-HBs antibody titer >= 10 IU/L) at 1 year [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    To determine the seroprotective rate at 1 year of each of the vaccination regimens.

  • Number of subjects with adverse events after vaccination [ Time Frame: 180 days ] [ Designated as safety issue: Yes ]
    Adverse events include pain at injected site, swelling at injected site, redness at injected site, fever, headache, fatique and anaphylaxis

Detailed Description:

HIV and HBV share similar risk factors and routes of transmission. HIV/HBV coinfection is associated with greater chance of chronic HBV carrier state, higher level of HBV replication and increasing its potential for transmission. Currently, there are no concrete data to determine the best HBV vaccination schedule in HIV-infected patients. Standard HBV vaccination (20 μg at 0, 1 and 6 months) gives seroconversion rate of 33-63% in HIV-infected individuals compared with >90% in healthy individuals. This study aims to compare the efficacy of an intensive standard-dose regimen (0, 1, 2 and 6 months) to a standard-dose regimen (0,1 and 6 months) and to compare the seroconversion rate of an intensive double-dose regimen (40 μg at 0,1,2 and 6 months) to a standard-dose regimen (20 μg at 0,1 and 6 months) of HBV vaccine in HIV-infected adult patients with CD4 level above 200 permm3 and suppressed viral load.
