Abstract
Infection with the human immunodeficiency virus type 1 (HIV-1) results in decreased cell-mediated immunity, which includes decreased delayed hypersensitivity to skin test antigens. HIV-1 seropositivity and skin test reactivity to purified protein derivative (PPD) were determined among 2042 healthy Haitian adults with normal chest radiographs. Among HIV-1-seropositive individuals, 52.3% (146/279) had PPD reactions ⋟10 mm compared with 67.2% (1184/1763) of the seronegative adults (P <.001). However, the percentage of HIV-1-seropositive individuals with PPD reactions ⋟5 mm was similar to the percentage of seronegative adults with PPD reactions ⋟10 mm (180/279 [64.5%] vs. 1184/1763 [67.2%]). Assuming that the rate of prior infection with Mycobacterium tuberculosis was similar for HIV-1-seronegative and -seropositive populations, these data provide support for the recent recommendations to use induration of >5 mm as evidence of past infection with M. tuberculosis in HIV-1 seropositive adults.
