PURPOSE: It was to determine the prevalence of Chlamydia trachomatis and the risk factors associated with infection in endocervical specimens from women seen in outpatient Obstetrics and Gynecology. METHODS: Samples of endocervical secretion of 200 women treated at the University Hospital of the Federal University of Rio Grande were analyzed for the presence of C. trachomatis by polymerase chain reaction (PCR) using primers that amplify CT05/CT06 281 base pairs of the main outer membrane protein of C. trachomatis. All participants completed a pre-coded and self-report questionnaire. Data were analyzed with the SPSS 17.0 software; for multivariate analysis it was used Poisson regression. RESULTS: Of the 200 women who were included in the study, the prevalence of infection with C. trachomatis was 11% (22 patients) and these 55 (27.5%) were positive for HPV. Risk factors associated with infection by C. trachomatis were: 8 years or less of schooling (p<0.001), family income below the poverty level (p=0.005), first intercourse at age 15 or less (p=0.04) and being a carrier of the virus HIV (p<0.001). After multivariate analysis, only the variables of schooling or less than eight years (PR 6.0; 95%CI 1.26 - 29.0; p=0.02) and presence of HIV (RP 14.1; 95%CI 3.4 - 57.5; p<0.001) remained statistically significant. CONCLUSIONS: The prevalence of C. trachomatis in endocervical specimens by PCR was 11%. The factors associated with a higher infection by C. trachomatis were lower education and being HIV positive.

PURPOSE: To determine the HPV prevalence and genotypes and to identify factors associated with infection in pregnant and non-pregnant women with positive or negative HIV-1, treated in Gynecology and Obstetrics Ambulatories and in Health Primary Units, in Rio Grande, Rio Grande do Sul State, Brazil. METHODS: Cervical cells samples from 302 patients were analyzed for HPV presence and genotypes were determined by nested and sequencing polymerase chain reaction. We calculated prevalence ratios associated with the studied variables by Fisher's exact or χ² tests, and Poisson's regression. Women with insufficient material were excluded from the study. RESULTS: HPV was detected in 55 of the 302 women included in the study (18.2%); of these, 31 were pregnant, showing a significant association for HPV (p=0.04) when compared to non-pregnant ones. Risk factors for the infection were: patients aged <20 years-old (p=0.04), early initiation of sexual life (p=0.04), absence of cytological test (p=0.01), diagnosis of altered cytology (p=0.001), and counting <349 cells/mm³ (p=0.05). However, multi-parity was found to be a protective factor for the infection (p=0.01). Multivariate analysis showed that age <20 years-old (PR=2.8; 95%CI 1.0 - 7.7, p=0.04) and an altered cytological result (PR=11.1; 95%CI 3.0 - 4.1, p=0.001) were significantly associated with infection. HPV genotype was determined in 47 samples (85.4%) presenting one genotype per infection: eight HPV 16 and 58; six HPV 6; four HPV 18 and 33; three HPV 53 and 82; two HPV 83 and 61; one HPV 31, 35, 45, 64, 68, 71 and 85. CONCLUSIONS: The prevalence of HPV detection was 18.2%, the most frequent genotypes were 16 and 58, and sociodemographic and gynecological factors were associated with viral infection.
