AbstractObjectives1To assess the prevalence of cervical epithelial abnormalities in female sexual partners of men with anogenital warts.2To examine the possible association between non‐HPV lower genital tract infection, and cervical epithelial abnormalities.DesignRetrospective review of the medical records of all female sexual partners of men with anogenital warts attending the GUM clinic in 1990.Setting and patientsThe department of Genito‐Urinary Medicine (GUM), Royal Victoria Hospital, Belfast. Sixty‐two female sexual partners of men with anogenital warts.MethodsCervical cytology and colposcopy was performed on all patients. Biopsies were taken of colposcopically identified cervical epithelial abnormalities, Non‐HPV lower genital tract infection was detected by routine genito‐urinary screening. Demographic data and sexual history were obtained by questionnaire.Outcome measuredOverall prevalence of cervical epithelial abnormalities and correlation to the presence of non‐HPV lower genital tract infection in the female.ResultsThe overall prevalence of cervical epithelial abnormalities detected with colposcopy and biopsy was 46.8%. The prevalence of koilocytosis and cervical intraepithelial neoplasia (CIN) was 69.6% when non‐HPV lower genital tract infection was detected by routine genito‐urinary screening. When no infection was detected the prevalence was
