Abstract
The prevalence of pharyngeal gonorrhoea in human immunodeficiency virus (HIV)-positive men who have sex with men (MSM) is not entirely known. We cultured the pharynx of 264 asymptomatic HIV-positive MSM in downtown Madrid. A questionnaire on sexual and drug use risk behaviours was also administered. Gonococci were isolated in 25 (9.5%). Among the whole study population, 65% had a history of sexual intercourse with two or more partners on a single day and 26% were involved in group sex with other men. Only 29% regularly used condoms in all sexual encounters and 63% used condoms only in insertive anal intercourse. When asked about oral sex, 89% of patients engaged in insertive and/or receptive oral sex and 86% recognized that they did not regularly request the use of condoms when practising “fellatio” on a partner. Cocaine, crystal methamphetamine or alcohol use and a previous history of ≥1 sexually transmitted infection were significantly more common among culture-positive patients. Gonococcal colonization of the pharynx was self-limited in patients that were not treated and re-cultured a mean 18.5 ± 5.2 days after diagnosis. Asymptomatic pharyngeal gonorrhoea is common among HIV-positive MSM and may contribute to the increasing epidemic of gonorrhoea in Madrid.
