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.
