Prevalence and concordance of oral and genital HPV in women positive for cervical HPV infection and in their sexual stable partners: An Italian screening study.

Abstract

ObjectivesThis cross-sectional study aimed to evaluate the prevalence and type of oral HPV-infection in women with a cervical HPV-lesion and in the oral and genital mucosa of their male partners.MethodsThe study group comprised 44 sexually-active women, 20–45 years with abnormal PAP smear, not more than 6 months prior to referral together with the male partners cohabiting in stable partnerships. A detailed questionnaire was administered concerning the HPV-related risk factors. Oral swabs, oral rinses, cervical swabs and urine samples were collected. HPV DNA was detected using two different polymerase chain reactions (PCRs): MY09-11 and FAP59-64. Positive samples were genotyped by Sanger sequencing and the INNO-LiPA HPV Genotyping Extra II probe assay. The association with risk factors was assessed by fitting a generalized model, using the General Linear Model function in the R-software; correlations were calculated between all data.ResultsHPV was detected in 84% of Cervical Samples, in 24.3% of oral samples and in one urine sample. Only 27% of the HPV-positive results were identical with both PCR DNA assays.8 male had oral HPV-positive samples different from women cervical samples. In one couple the urine-male sample had the same HPV present in the female-cervical sample. A significant association resulted between women/oral sex practices and men/n. of partners.ConclusionsThis study reports that women (20.4%) with a diagnosis of cervical-HPV and their male partners (30,7%) are at high risk for subclinical oral HPV infection.
