ABSTRACT Introduction: Cervical cancer remains an important burden for HIV-infected women in the era of combination antiretroviral therapy. Recommendations for cervical screening in these women diverge and may include high-risk HPV (HRHPV) testing. We aimed to evaluate the clinical usefulness of a single HRHPV testing for cervical screening of HIV-infected women. Methods: 723 HIV-infected women from a Brazilian prospective cohort were included between 1996 and 2012. Inclusion criteria were: normal cervical cytology at baseline and having a HRHPV-test at baseline. We calculated incidence rates of any squamous intraepithelial lesion (SIL) and high grade SIL+ (HSIL+) and negative predictive values (NPV) within 12 and 36 months. Hazard Ratios were obtained using Cox proportional hazards regression models. Results: Incidence rate for both outcomes was low (9.9 cases per 100 PY [95% CI 8.8–11.0] for any SIL and 1.3 cases per 100 PY [95% IC 0.9–1.8] for HSIL+). Women with a HRHPV positive status at baseline had 1.7-fold (95% CI 1.3–2.2) and 3.2-fold (95% CI 1.5–7.1) increased risk of presenting any SIL and HSIL+, respectively, during follow-up. Negative-HRHPV test presented high NPV for both periods and outcomes (any SIL: 92.4% [95% CI 89.7–94.6] for 12 months and 80.9% [95% CI 77.2–84.3] for 36 months; and HSIL+: 99.8% [95% CI 98.9–100.0] for 12 months and 99.0 [95% CI 97.6–99.7] for 36 months). Conclusions: Incidence of any and high grade cytological abnormality was significantly higher among HIV-infected women with positive-HRHPV test. A single negative-HRHPV test helped reassure follow-up free of cytological abnormalities through three years of follow-up in HIV-infected women with negative cytology.

OBJETIVO: este trabalho buscou estimar a prevalência das infecções pela Chlamydia trachomatis e pela Neisseria gonorrhoeae em gestantes de seis cidades brasileiras e identificar sua associação com variáveis socioeconômicas e demográficas. MÉTODOS: este estudo faz parte de uma pesquisa multicêntrica, de âmbito nacional, transversal, com amostra de gestantes atendidas entre 2004 e 2005 nos serviços de pré-natal da atenção básica de seis cidades brasileiras (Manaus, Fortaleza, Goiânia, Rio de Janeiro, São Paulo e Porto Alegre). Amostras cérvico-vaginais foram coletadas de todas as gestantes e submetidas posteriormente à técnica de captura híbrida para identificação da clamídia e do gonococo. As informações sociodemográficas, médicas, sexuais e obstétricas foram coletadas por meio de questionários específicos. Para avaliar os fatores de risco associados à infecção por gonorréia e clamídia, foi utilizado o Odds Ratio (OR). A análise estatística foi feita com a utilização do teste t de Student, o χ2 e o teste exato de Fischer. RESULTADOS: foram recrutadas 3.303 gestantes, cuja idade média foi 23,8 anos (±6,9). As prevalências da infecção por clamídia e pelo gonococo foram, respectivamente, 9,4 e 1,5%. Dez por cento das gestantes com infecção por clamídia apresentaram presença simultânea do gonococo. O risco de apresentar uma dessas infecções foi duas vezes maior para as gestantes com menos de 20 anos. Os principais preditores da infecção foram: idade menor de 20 anos, raça/cor negra, ser solteira ou separada e relato de mais de um parceiro no último ano. CONCLUSÕES: este estudo observou prevalências elevadas da infecção pela Chlamydia trachomatis e pela Neisseria gonorrhoeae em gestantes brasileiras. O principal fator de risco para a infecção foi ter menos de 20 anos de idade.

PURPOSE: This paper has aimed at estimating the prevalence of infections by Chlamydia trachomatis and by Neisseria gonorrhoeae in pregnant women from six Brazilian cities, identifying its association with socio-economical and demographic variables. METHODS: This study has been part of a multicentric nationwide transversal research, with samples of pregnant women attended from 2004 to 2005 in basic attention pre-natal services from six Brazilian cities (Manaus, Fortaleza, Goiânia, Rio de Janeiro, São Paulo and Porto Alegre). Cervico-vaginal samples have been collected from all the pregnant women, and have afterwards been submitted to the hybrid capture technique in order to identify chlamydia and gonococcus. Socio-demographic, medical, sexual and obstetric information have been collected through specific questionnaires. The Odds Ratio (OR) has been used to evaluate risk factors associated to infection by gonorrhea and chlamydia. Statistical analysis has been done with the t-Student, χ2 and Fisher's exact tests. RESULTS: Three thousand and three pregnant women with an average age of 23.8 years old (±6.9) took part in the study. Infection prevalence by chlamydia and gonococcus were 9.4 and 1.5, respectively. Ten per cent of the pregnant women with chlamydia have presented gonococcus simultaneously. The risk of presenting one of those infections was two times higher for the women under 20. The infection main predictors have been: age under 20, race/black, single/separated and report of over one partner in the previous year. CONCLUSIONS: This study has observed high prevalence of infection by Chlamydia trachomatis and by Neisseria gonorrhoeae in Brazilian pregnant women. The main risk factor for the infection has been to be under 20 years old.
