To determine the risk of active tuberculosis associated with human immunodeficiency virus (HIV) infection, we prospectively studied 520 intravenous drug users enrolled in a methadone-maintenance program. Tuberculin skin testing and testing for HIV antibody were performed in all subjects. Forty-nine of 217 HIV-seropositive subjects (23 percent) and 62 of 303 HIV-seronegative subjects (20 percent) had a positive response to skin testing with purified protein derivative (PPD) tuberculin before entry into the study. The rates of conversion from a negative to a positive PPD test were similar for seropositive subjects (15 of 131; 11 percent) and seronegative subjects (26 of 202; 13 percent) who were retested during the follow-up period (mean, 22 months). Active tuberculosis developed in eight of the HIV-seropositive subjects (4 percent) and none of the seronegative subjects during the study period (P less than 0.002). Seven of the eight cases of tuberculosis occurred in HIV-seropositive subjects with a prior positive PPD test (7.9 cases per 100 person-years, as compared with 0.3 case per 100 person-years among seropositive subjects without a prior positive PPD test; rate ratio, 24.0; P less than 0.0001). We conclude that, although the prevalence and incidence of tuberculous infection were similar for both HIV-seropositive and HIV-seronegative intravenous drug users, the risk of active tuberculosis was elevated only for seropositive subjects. These data also suggest that in HIV-infected persons tuberculosis most often results from the reactivation of latent tuberculous infection; our results lend support to recommendations for the aggressive use of chemoprophylaxis against tuberculosis in patients with HIV infection and a positive PPD test.

We examined attitudinal and demographic correlates of antiretroviral acceptance and adherence among incarcerated HIV-infected women. Structured interviews were conducted with 102 HIV-infected female prisoners eligible for antiretroviral therapy. Three quarters of the women were currently taking antiretroviral agents, of whom 62% were adherent to therapy. Satisfaction was very high with the HIV care offered at the prison; 67% had been first offered antiretroviral agents while in prison. Univariate and multivariate analyses showed acceptance of the first offer of antiretroviral therapy to be associated with trust in medication safety, lower educational level, and non-black race. Current acceptance of therapy was associated with trust in the medication's efficacy and safety. Medication adherence was correlated with the patient-physician relationship and presence of emotional supports. Nearly one half of these HIV-seropositive women were willing to take experimental HIV medications in prison. This was correlated with satisfaction with existing health care, the presence of HIV-related social supports, and perceived susceptibility to a worsening condition. Acceptance and adherence with antiretroviral agents appear to be significantly associated with trust in medications, trust in the health care system, and interpersonal relationships with physicians and peers. Development of models of care that encourage and support such relationships is essential for improving adherence to antiretroviral therapy, especially for populations that have historically been marginalized from mainstream medical care systems.

Insomnia is widespread and underdiagnosed in HIV-seropositive ambulatory patients. Insomnia is especially prevalent among those with cognitive impairment. These findings suggest the importance for clinicians to inquire specifically about sleep disorders in HIV-seropositive patients. Prompt diagnosis and treatment may improve the quality of life in patients living with HIV.
