RESUMO
Objetivo: Analisar a prevalência dos resultados positivos para ASC em uma população da rede privada em Caxias do Sul e sua associação com o HPV. Métodos: Foram analisados resultados de exames citopatológicos do colo uterino no período de 2015 a 2017. Para presença de HPV foram avaliados os resultados histopatológicos da biópsia e de biologia molecular por reação em cadeia polimerase (PCR). Resultados: A prevalência de ASC foi de 2,48%, sendo que 58% das pacientes realizaram seguimento. A histopatologia mostrou prevalência de HPV, associado às lesões cervicais em 46,4% e 59,4% para ASC-US e ASC-H respectivamente. A prevalência de HPV no teste de PCR foi de 30,4%, sendo os subtipos mais prevalentes o HPV16 e 18. Conclusão: O percentual de exames de ASC em uma população de Caxias do Sul mostrou-se dentro dos valores adequados. Na histopatologia houve uma maior associação de ASC-H com lesões de alto grau e presença de HPV. Isso mostra a necessidade e a importância do seguimento das pacientes com resultados de ASC, principalmente para ASC-H.

OBJECTIVE: The aim of this study was to assess the correlation between atypical squamous cells (ASC) and inflammatory infiltrate and vaginal microbiota using cervical liquid-based cytological (SurePath®) and high-risk human papillomavirus (HR-HPV) tests. STUDY DESIGN: A cross-sectional study was conducted using a 6-year database from a laboratory in Fortaleza (Brazil). Files from 1,346 ASC cases were divided into subgroups and results concerning inflammation and vaginal microorganisms diagnosed by cytology were compared with HR-HPV test results. RESULTS: An absence of specific microorganisms (ASM) was the most frequent finding (ASC of undetermined significance, ASC-US = 74%; ASC - cannot exclude high-grade squamous intraepithelial lesion, ASC-H = 68%), followed by bacterial vaginosis (ASC-US = 20%; ASC- H = 25%) and Candida spp. (ASC-US = 6%; ASC-H = 5%). Leukocyte infiltrate was present in 71% of ASC-US and 85% of ASC-H (p = 0.0040), and in these specific cases HR-HPV tests were positive for 65 and 64%, respectively. A positive HR-HPV test was relatively more frequent when a specific microorganism was present, and Candida spp. was associated with HR-HPV-positive results (p = 0.0156), while an ASM was associated with negative HR-HPV results (p = 0.0370). CONCLUSION: ASC-US is associated with an absence of inflammation or vaginosis, while ASC-H smears are associated with Trichomonas vaginalis and inflammatory infiltrate. A positive HR-HPV is associated with Candida spp. in ASC cytology.
