Impact of combined mycoplasmataceae and HPV co-infection on females with cervical intraepithelial neoplasia and carcinoma.

PURPOSE The concurrent prevalence investigation of human papillomavirus (HPV), Mycoplasma hominis (Mh) and Ureaplasma urealyticum (Uu) in women in order to estimate the association of co-infection with cervical lesions. METHODS The study cohort comprised 120 women with no cervical lesions (control group) and 62 women with abnormal cytological findings from the cervix (cervical intraepithelial lesion/neoplasia) as study group. A combination of molecular analyses was implemented. RESULTS The presence of HPV infection was shown in 52/62 (83.9%) of women with abnormal cytology. Women with cervix cytological findings were shown to have 17.6 times higher risk for Mh and Uu co-infection (p=0.001). HPV and Uu co-infection were detected with a higher prevalence among women with CIN 3 and invasive cancer. CONCLUSION These findings are consistent with the notion that microbial co-infections may play an important role in persistent inflammation and progression of cervical lesions.
