Relationship of HPV infection and BV, VVC, TV: a clinical study based on 1 261 cases of gynecologic outpatients

Abstract

Objective: To Explore the relationship between HPV infection and bacterial vaginosis(BV), vulvovaginal candidiasis(VVC), and trichomonal vaginitis(TV). Methods: Clinical data from 1 261 gynecologic outpatients who underwent the vaginal microecology and HPV type detection during June 2015 to December 2015 were collected and analyzed in the First Affiliated Hospital of Xi'an Jiaotong University. Results: In 1 261 patients, 328 cases infected with HPV, infection rate was 26.01%(328/1 261); vaginal infectious disease in 328 cases of HPV infections were 219 cases(66.8%, 219/328), vaginal infectious diseases in 933 cases of HPV uninfected were 503 cases(53.9%, 503/933), incidence of vaginal infectious disease in HPV infected patients was higher than that in HPV uninfected patients(χ2=5.87, P=0.01). 142 cases of BV had 54 cases infected with HPV(38.0%, 54/142), 296 cases of intermediate type BV had 88 cases infected with HPV(29.7%, 88/296), 231 cases of normal vaginal microecology had 51 cases infected with HPV(22.1%, 51/231), 99 cases of VVC had 15 cases infected with HPV(15.2%, 15/99), 2 patients with TV had 0 cases infected with HPV(0/2), HPV infection rate in BV, intermediate type BV patients were significantly higher than normal patients(P<0.05), while there were no statistical differences among VVC, TV and normal patients(P>0.05). The intensity of HPV infection were positively correlated with BV, intermediate type BV(OR=2.17, 95% CI: 1.37-3.43, P<0.01; OR=1.49, 95% CI: 1.00-2.22, P= 0.04); while, VVC, TV were uncorrelated with HPV infection(all P>0.05). Conclusions: BV, intermediate type BV are positively correlated with HPV infection, especially for the high-risk HPV. VVC and TV are not correlated with HPV infection.
