MUNOZ, Dany et al. Risk of sexual relationship and seroprevalence of infection for HIV-HTLV-I, syphilis and hepatitis B in non endovenous drug addicts of Lima, Peru. Rev Med Hered [online]. 1997, vol.8, n.3, pp.92-103. ISSN 1018-130X.

Objective: To investigate the prevalence of risk sexual behavior practices for infection by Sexually Transmitted Diseases (STD) and seroprevalence of infection by HIV, HTLV-1, Hepatitis B and Syphilis in non-endovenoous drug abusers (NEDA) from Lima and to identify if they could be considered as another group of high risk to acquire HIV infection. Material and methods: Anonymous survey through direct interview on sexual practices and histories of STD, and serologic analysis for antibodies against HIV-1, HTLV-1, HBc and T. pallidum in 298 NEDA volunteers in the Instituto de Salud Mental Honorio Delgado-Hideyo Noguchi and 10 non-Governmental Organizations ("Therapeutic Communities") from Lima, between April and August 1996. Results: Five (1.7%) serum samples were positive to HIV-1 and one was indeterminate (positive ELISA and WB band gp present). Seven (2.3%) were positive to HTLV-1. Thirty-four (11.4%) were positive to Ab Anti-HBc and one (0.3%) RPR reactive. The age average was 28.8 ± 8.1 years. the average time of drug consumption more frequently found was 6.9 ± 6.2 years, 80% with more than one year. During the consumption period of time: the average sexual partner was 53.9 ± 243 with a median of 15; 79% had sexual intercourse with steady sexual partners, 82% casual intercourses, 62.4% with female sex workers and, 60% with homosexuals; the consistent use of condoms is low with all type of sexual partners and in all type of sexual intercourses but significantly increase in the case of sexual relations with female sex workers. With the drug abuse, there is an increasing tendency of the number of sexual partners and more frequency of developing some risk sexual practices, such as anal coitus with all type of sexual partners, and a high percentage (75%) has sexual relations when they have consumed drugs, and 32.9% exchange sex for drugs. 43.6% referred histories of STD during the past 15 years, with gonorrhea being the most frequent (37.9%). Conclusion: Non-endovenous drug abusers present risk sexual behavior practices that explain the prevalence of infection found by HIV-1, HTLV-1, and HBV and should be considered as another group of frequent transmission for HIV and other STD in Peru, this situation should involve actions for education and prevention directed to this group of population.
