Male transvestite prostitutes and HIV risk.

Human immunodeficiency virus (HIV)-1, syphilis, and hepatitis B prevalence and associated risk factors were assessed among male transvestite prostitutes. Structured street-level interviews were conducted with 53 respondents in Atlanta, Ga, from July 1990 through July 1991. Test results from serum samples revealed that 68% were seropositive for HIV-1, 81% had seromarkers for syphilis, and 80% had seromarkers for hepatitis B. Univariate logistic regression analysis indicated that seromarkers for syphilis and Black race were the primary factors associated with HIV-1 infection. The results show that transvestite prostitutes are a heterogenous population and distinct from nontransvestite prostitutes; specific outreach is thus needed. Targeted interventions should address the sexual and drug-use-related HIV risk behaviors of transvestite prostitutes.

Sexual practices in the transmission of hepatitis B virus and prevalence of hepatitis delta virus infection in female prostitutes in the United States.

OBJECTIVE: To evaluate heterosexual transmission of hepatitis B virus (HBV) and the prevalence of hepatitis delta virus (HDV) infection in female prostitutes. DESIGN: Survey. SETTING: Sexually transmitted disease clinics, drug treatment programs, detention centers, and/or outreach efforts in eight areas in the United States. PARTICIPANTS: A total of 1368 female prostitutes 18 years of age or older. OUTCOME MEASURES: Seropositivity for HBV and HDV infection. RESULTS: The overall prevalence of past or present HBV infection was 56%: 74% in women who were injecting-drug users (IDUs), 38% in women reporting no history of injecting-drug use (non-IDUs), 51% in whites, 55% in blacks, and 67% in Hispanics. Of 21 HBV carrier IDUs, 21% had HDV infection; of 18 HBV carrier non-IDUs, 6% had HDV infection. In non-IDUs (49%), risk factors for HBV infection were a history of having penile-anal intercourse (odds ratio [OR], 3.1; 95% confidence limits [CL], 1.3, 7.3) and seropositivity for syphilis and human immunodeficiency virus (HIV) infection. In IDUs, factors associated with an increased risk of infection, in addition to behaviors related to injecting-drug use, were the number of lifetime sexual partners, having sexual partners from groups at high risk for HBV infection, and seropositivity for syphilis and HIV infection; spermicide and/or diaphragm use was associated with a markedly decreased risk of HBV infection among blacks (OR, 0.1; 95% CL, 0.03, 0.4) and Hispanics (OR, 0.2; 95% CL, 0.06, 0.9). CONCLUSION: This is the first study to suggest that having anal intercourse and failing to use vaginal contraceptives may facilitate transmission of HBV to women. Our data support guidelines that recommend hepatitis B vaccination for prostitutes and persons with a history of sexually transmitted diseases or multiple sexual partners.

Intravenous drug abusers and the acquired immunodeficiency syndrome (AIDS). Demographic, drug use, and needle-sharing patterns.

We studied the demographic characteristics, drug use patterns, and sexual habits of intravenous (IV) drug abusers to further define this population at risk for acquired immunodeficiency syndrome (AIDS). Sixteen IV drug abuser patients with AIDS, 24 IV drug abuser patients with AIDS-related complex (ARC), and 14 IV drug abuser controls without evidence of AIDS or ARC were evaluated. The subjects in each group were similar demographically, in drug use practice, and in sexual orientation and experience. Of the AIDS and ARC patients, 34 (88%) of 40, including all seven homosexual men, shared needles, as did all drug abusers without AIDS or ARC. Seventy-four percent of patients, including all homosexual men, attended "shooting galleries," where anonymous multiple-partner needle sharing took place. Needle sharing supports the hypothesis of AIDS transmission by a blood-borne route, can explain the spread of AIDS and the high rate of seropositivity to the putative AIDS agent among IV drug abusers, and is a logical link between IV drug abusers and male homosexuals, the two largest groups with AIDS.
