Characteristics of bacterial vaginosis infection in cervical lesions with high risk human papillomavirus infection.

From October 1, 2009 to October 31, 2013, a total number of 3502 women who visited Fengxian Hospital, Southern Medical University were enrolled in this study. All participants gave informed consent and agreed to HPV, BV, chlamydia, mycoplasma and thinprepcytologic test (TCT). In addition, all women took histopathologic examination under colposcopy. Statistical analyses were done using SPSS 17.0 for windows (IBM). In present study the overall BV-positive rate was 9.25%. The top three high risk HPV types were listed as follows (in descending order): HPV16, 52, 58. Moreover, our data showed BV infection tended to occur in the HPV positive women, HPV infection also tended to occur in the BV positive women. Most of the women who present HPV with BV infection were younger than 30 years old. We also found that CIN and cervical cancer occurred mainly in HPV/BV positive and HPV with BV positive group. BV infection and HPV infection may haveconsistency or synergies. HPV with BV infection may increase the incidence of CIN and cervical cancer.
