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.

Objective. To study the relationship of HIV infection and drug use with the onset of natural menopause. Methods. Our analyses used the World Health Organization's definition of menopause (i.e., the date of the last menstrual period is confirmed after 12 months of amenorrhea) and baseline data from a prospective study. Semiannual interviews were conducted. Levels of HIV antibody and CD4 + cell counts were obtained. Menopause was identified at baseline or during 12 months of follow-up. Women ingesting reproductive hormones were excluded. Logistic regression analyses were used to assess factors associated with menopause.Results. Of 571 women, 53% were HIV infected, and 52% had used heroin or cocaine in the previous 5 years. The

This study investigated the relation between suicide attempts and immigrant generation status using the Latino subset of the National Longitudinal Study of Adolescent Health, a school-based, nationally representative sample. This study also examined whether generation status predicted risk factors associated with elevated suicide behaviors, namely illicit substance use, problematic alcohol use, and depressive symptoms. Finally, hypothesizing that elevated depressive symptoms and substance use mediate the relation between immigrant generation status and suicide attempts among Latino adolescents, a path model was tested. Our findings revealed immigrant generation status was a determinant for suicide attempts, problematic alcohol use, repeated marijuana use, and repeated other drug use for Latino adolescents. US-born Latinos with immigrant parents (i.e., second-generation youth) were 2.87 (95% CI, 1.34, 6.14) times more likely to attempt suicide, 2.27 (95% CI, 1.53, 3.35) times more likely to engage in problematic alcohol use, 2.56 (95% CI, 1.62, 4.05) times more likely to engage in repeated marijuana use, and 2.28 (95% CI, 1.25, 4.17) times more likely to engage in repeated other drug use than were foreign-born youth (i.e., first-generation youth). Later-generations of US-born Latino youth with US-born parents were 3.57 (95% CI, 1.53–8.34) times more likely to attempt suicide, 3.34 (95% CI, 2.18–5.11) times more likely to engage in problematic alcohol use, 3.90 (95% CI, 2.46, 6.20) times more likely to engage in repeated marijuana use, and 2.80 (95% CI, 1.46, 5.34) times more likely to engage in repeated other drug use than were first-generation youth. Results from the path analysis indicated that repeated other drug use may mediate the effect of generation status on suicide attempts.

HIV-infected injection-drug users have progression to AIDS at rates comparable to those of other HIV-infected groups, but they have substantial pre-AIDS morbidity and mortality, particularly from bacterial infections, which also appear to predict disease progression.

A behavioral intervention for men who have sex with men (MSM) was created for online delivery. The nine-minute video drama "The Morning After" (www.hivbigdeal.org) was designed to promote critical thinking about HIV risk. MSM were recruited for the evaluation through banner ads on a subscription-based gay sexual meeting web site. Participants viewed the intervention online and completed online behavioral questionnaires at enrollment and three month follow-up. Each participant served as his own control. No participant incentives were provided. Follow-up was completed by 522 (54%) of 971 eligible men. Men completing follow-up were similar to those who did not by age and prevalence of unprotected anal intercourse (UAI) but reported more lifetime sex partners. They also differed somewhat by race, education, and HIV testing. In the three months after the intervention, men were significantly more likely to disclose HIV status to partners (odds ratio [OR] = 3.37, p<0.001) and less likely to report a casual partner or UAI in their most recent sexual encounter than at baseline. Of 120 men HIV tested during follow-up, 17 (14%) reported being HIV seropositive. These findings show that MSM at high risk for HIV will participate in a brief online video intervention designed to engage critical thinking and that significant, self-reported increases in HIV disclosure and decreases in risk behavior occurred three months after MSM viewed the video.

OBJECTIVES. The purpose of this study was to examine factors associated with heroin use during methadone maintenance treatment. METHODS. Logistic regression statistical models were used to examine data obtained in a cross-sectional sample of 652 methadone patients. RESULTS. Heroin use during the 3 months prior to interview was shown to be greatest among (1) patients maintained on methadone dosages of less than 70 mg/day (adjusted odds ratio [OR] = 2.1, 95% confidence interval [CI] = 1.3, 3.4) and (2) patients who used cocaine during treatment (adjusted OR = 5.9, 95% CI = 3.8, 9.1). These results were independent of treatment duration, treatment compliance, alcohol use, and socioeconomic factors. Cocaine users were more likely than nonusers of cocaine to use heroin at all methadone dosage levels. CONCLUSIONS. This study confirms and extends past research showing high-dose methadone maintenance to be important to heroin abstinence. Further investigation of the independent association between heroin use and cocaine use is needed.

The completion of isoniazid chemoprophylaxis was associated with a marked reduction in tuberculosis risk among tuberculin reactors and anergic persons in this high-risk population. These data support aggressive efforts to provide a complete course of preventative therapy to HIV-infected tuberculin reactors, and lend weight to the findings of others that isoniazid can reduce the rate of tuberculosis in high-risk anergic HIV-infected persons.
