Abstract
BACKGROUND: Some studies demonstrated that female genital mycoplasmas play important roles in human papillomavirus (HPV) infection, abnormal cervical cytopathology, and cervical cancer. However, those results remained inconclusive. We aimed to perform a systematic review and meta-analysis to investigate the association between female genital mycoplasmas and those disorders. METHODS: Computerized databases were comprehensively searched before 26 January 2017. Pooled odd radios (ORs) and correlative 95% confidence intervals (CIs) were adopted to evaluate the strength of association. RESULTS: Our meta-analysis included 22 studies with 16,181 participants. Ureaplasma urealyticum and Ureaplasma parvum were associated with a significantly increased risk of overall HPV infection (OR 1.57, 95% CI 1.05-2.34; OR 3.02, 95% CI 2.10-4.33, respectively), and U. urealyticum and Mycoplasma genitalium were associated with a significantly increased risk of high-risk HPV infection (OR 1.37, 95% CI 1.05-1.80; OR 1.50, 95% CI 1.11-2.02, respectively). In addition, U. urealyticum, U. parvum, and Mycoplasma hominis were associated with a significantly increased risk of abnormal cervical cytopathology (OR 1.51, 95% CI 1.23-1.85; OR 1.41, 95% CI 1.10-1.80; OR 1.48, 95% CI 1.10-1.99, respectively). CONCLUSION: We found that U. urealyticum and M. genitalium may increase the risk of high-risk HPV infection, while U. urealyticum, U. parvum, and M. hominis may increase the risk of abnormal cervical cytopathology.
