SUMMARY:
Bacterial sexually transmitted Infections (STI), especially gonorrea and chlamydia are very prevalent in Brazil and in the world. Men who have sex with men (MSM) and transgender women (TW) are disproportionatelly affected by these pathogens, on account of a higher context of vulnerability. Adolescents aged 15-19, specially from sexual minorities, are another important population in this context.
This research aimed to estimate the baseline prevalence of Neisseria gonorrhoeae and
Chlamydia trachomatis, identify behavioural and socia factor linked to these infections and estimate the prevalence of extragenital infections by these pathogens among 246 adolescent MSM and TW who participated in the PrEP15-19 study in Salvador-BA city. Social and behavioural data were collected by interview, with oral, anal and uretral samples collected from participants. The samples were tested by qPCR for the presence of NG and CT.
Among the participants, 15.0 % (37/246) tested positive for NG and 4.9% (12/246) tested positive for CT. Coinfection occurred in only one case (0.4%). For the presence of NG, the factors that were linked the most to infection were: having casual partnership in the last 3 months (RP=2.18; IC95%: 0.99-4.76), practice receptive anal intercourse (RP=3.09; IC95%: 1.13-8.43) or insertive anal intercourse (RP= 1.98; IC95%: 0.97-4.03), drug use before or during sexual intercourse (RP=3.00; IC95%: 1.48-6.09). No statistically significant factors were identified for the presence of CT. Most infections by these pathogens would not have been identified if only urogenital samples were
collected, with 87.5% of NG and 61.48% of CT infections occurring on extragenital sites.
This study was one of the first researches conducted on Brazil studying the presence of theses infections among adolescent MSM and TW, as well as identifying the social and behavioral factors
associated with these infections, allowing the development of strategies on public health aimed at the
control of these epidemics taking in consideration the specific context of these populations.
