Skin tests were read after 48–72 h. A reaction to an antigen was considered positive if there was induration of >2 mm. Cutaneous anergy occurred more often in HIV-seropositive patients than in healthy controls (p < 0.001) and was most prevalent in patients with advanced HIV illness. HIV-seropositive patients with a positive tuberculin reaction were more likely to have active tuberculosis (TB) than HIV-seropositive patients without a positive tuberculin reaction (p < 0.001). Therefore, a TB diagnosis should be pursued in HIV-seropositive patients with a positive tuberculin reaction. © Lippincott-Raven Publishers.
