Prevalência de Chlamydia Trachomatis em mulheres atendidas pelo Sistema Único de Saúde (SUS)

Abstract

to determine cervical cytological changes, vaginal microbiota pattern and detect the presence of Chlamydia trachomatis and Human Papillomavirus (HPV) in women assisted by Health Unic System (SUS) of Brazil. Methodology: cross-sectional study, carried out in Passo Fundo-RS from November 2020 to June 2021 with women who underwent specular examination for collection of cervical-vaginal contents in liquid medium was performed to determine cytological changes by means of Pap smear staining and vaginal swab collection for evaluation of vaginal microbiota by means of Gram staining and Nugent Score. Sociodemographic and clinical data were obtained through a standardized questionnaire. The presence of C. trachomatis was detected by Real Time Polymerase Chain Reaction (RT-PCR) and the detection and typing 06 and 16 of HPV were determined by conventional PCR. The data were obtained in frequencies and the analysis of the relationship of the variables were performed using the X² test, with a significance level of 5%. Results: Twenty-two women were included during the study period, with a mean age of 37.23 ± 10.71 years, predominantly white, who could read and write and had only 1 sexual partner in the last year. Predominant vaginal microbiota of flora with a normal pattern (Flora I) (40.9%). Regarding liquid-based cytology, most women present absence of neoplasia, however provided the percussive lesion of cervical neoplasia (NICI / LSIL), ASC-H and ASC-US, both in one sample each (4.5% ) The positivity of C. trachomatis was observed in 4.5% of the sample, while the positivity of HPV was presented in 42.8% of the women, with type 06 HPV being predominant in 14.2% of the cases. Conclusion: The frequency of cytological changes and C. trachomatis presence are low in women of reproductive age assisted by SUS, while HPV positivity is high and might be associated with changes in vaginal microbiota, as bacterial vaginosis.
