Prevalência de Neisseria gonorrhoeae e Chlamydia trachomatis em homens atendidos em clínicas de DST de seis capitais brasileiras

Abstract

Objectives: To determine the prevalence of Neisseria gonorrhoeae(NG) and Chlamydia trachomatis (CT) infections and identified demographic, behavioral, and clinical correlates of these infections in men attending six STI clinics in Brazil. Methods: Multicentric, cross-sectional study performed among men attending STI clinics in Brazil. The study included STD clinics in six diverse cities in the five geographic regions of Brazil in 2005. Patients provided 20 ml of first catch urine for testing for NG and CT by DNA-PCR. Results: A total of 767 (92.9%) men were included in the study. The median age was 24 (IQR 21 30) years old. Prevalence of Chlamydia infection was 13.1% (95%CI 10.7%-15.5%) and gonorrhea was 18.4% (95%CI 15.7%-21.1%). Coinfection prevalence was 4.4% (95%CI 2.95%-5.85%) in men who sought assistance in STI clinics. Factors identified as being independently associated with Chlamydia trachomatis in the final multiple logistic model were being younger (15-24) [OR=1.4 (95%CI 1.01-1.91)], present urethral discharge [OR=4.8 (95%CI 1.52-15.05)], genital warts [OR=3.0 (95%CI 1.49-5.92)] and previous history of urethral discharge [OR=2.4 (95%CI 1.11-5.18)]. Variables associated with gonorrhea were being younger (15 to 24) [OR=1.5 (95%CI 1.09-2.05)], presence of urethral discharge [OR=9.9 (95%CI 5.53-17.79)], genital warts [OR=18.3 (95%CI 8.03-41.60)] and ulcer in clinical examination [OR=4.9 (95%CI 1.06-22.73)]. Conclusions: These findings have important implications for implementing education and prevention efforts directed toward men at risk of HIV/STD. A venue-based approach to offer routinely testing to men in STD clinic should be stimulated.
