The effects of tuberculosis (TB) on the kinetics of CD4+ T cells among HIV-infected individuals with early combination antiretroviral therapy (cART) after TB therapy initiation are poorly characterized. We conducted a case-control study with 15 HIV-TB-coinfected patients who initiated TB treatment and early cART, and 30 controls without TB who had similar CD4+ T cell counts and viral loads at the time of starting cART. We compared the rate of CD4+ T cell increase for 5 years after cART. The time to CD4 + T cell increase >250 cells/mm3 was significantly slower in HIV-TB-coinfected patients (p=0.015, by log rank test). HIV-TB-coinfected patients had significantly lower median CD4+ T cell counts at 5 years after cART (p=0.048). The difference in CD4+ T cell increase was observed only during the first 6 months after cART initiation (p=0.002). These data suggest that TB slows the rate of CD4+ T cell recovery at an early period after cART. The effects of TB on the long-term immunity of HIV-infected patients should be further evaluated.
