Molecular Detection of Human Papillomavirus (HPV) and Other Sexually Transmitted Pathogens in Cervical and Self-Collected Specimens

This study investigated the detection of high-risk Human Papillomavirus (hrHPV) and seven other pathogens associated with sexually transmitted infections (STIs) in matched clinician-collected cervical samples and self-taken vaginal and urine specimens collected from 342 asymptomatic women referred to colposcopy to evaluate (i) the concordance in the molecular detection of investigated pathogen in three different sample types; (ii) the analytical sensitivity and specificity of STIs detection on self-samples; and (iii) the distribution of STIs in hrHPV-positive and hrHPV-negative women. Pathogens detection was performed using Anyplex (TM) II HR and Anyplex (TM) II STI-7e, respectively. Good/substantial agreement was observed between cervical and self-taken samples in detecting hrHPV (kappa = 0.870 and kappa = 0.773 for vaginal and urine). The agreement between cervical and self-taken samples for detecting STIs was found to be significant (kappa = 0.779 and kappa = 0.738 for vaginal and urine), with almost perfect agreement between urine and vaginal specimens (kappa = 0.899). The positivity rate for all investigated STIs was found to be higher in hrHPV-positive compared to hrHPV-negative women. In conclusion, self-sampling proved to be a valid alternative to cervical samples to detect hrHPV and STIs, but further studies are required to evaluate the role of STI coinfections in cervical lesions development and progression.
