Resumo
Individuals deprived of their liberty are at high risk for syphilis, due to sexual and non-sexual risk behaviors, such as inconsistent condom use, sex for money and / or drugs, and multiple sexual partnerships. The objective of this study was to investigate the seroprevalence of syphilis infection in deprived men in the southern region of Goiás. Between September 2017 and May 2018, a cross-sectional study was conducted on 194 men deprived of liberty from a regional prison south of the state of Goiás. All participants were interviewed about socio-demographic characteristics, sexual and non-sexual risk behaviors for syphilis. Next, blood samples were collected for the detection of anti-T. pallidum antibodies by immunochromatographic treponemal test (rapid test). Positive samples were retested by the Venereal Disease Research Laboratory / VDRL. Active syphilis was considered positive in the rapid test and titers of VDRL ≥ 1: 8. Of the 194 samples tested by immunochromatographic examination, 11.8% (95% CI: 7.8-17.3%) were positive and 7.7% (95% CI: 4.7-12.5%) presented VDRL ≥ 1: 8. The prevalence of exposure to Treponema pallidum was 23 times higher than that estimated in Brazilian conscripts (95% CI: 0.45-0.61) and 8 times higher than that found in blood donors from São Paulo (95% CI: 1.31 -1.36). In multiple regression analysis, the prevalence of exposure to T. pallidum was 36% (RPaj: 0.39; 95% CI: 0.18-0.86) in individuals who reported sexual relations with sex workers when compared to those who did not have this characteristic. In addition, it was observed that the prevalence of active syphilis increased with increasing prison time (RPaj: 1.02, 95% CI: 1.00-1.08, p-value = 0.030). The results of this investigation show a high prevalence of syphilis in the men deprived of liberty investigated and indicate the need to implement strategies for prevention and control of infection in such individuals, including educational health actions, rapid and efficient diagnosis and appropriate treatment of cases of active syphilis.
