Abstract:

Objective: To study the relationship between vaginal microenvironment, interleukin-4(IL-4) and high-risk human papilloma virus(HR-HPV) infection of the cervix. Methods: From December 2018 to December 2019, 85 patients of childbearing age with cervical HR-HPV infection who were admitted to the First Affiliated Hospital of Dali University were selected as the observation group(Group A), and 83 patients with cervical HPV-negative physical examination during the same period were selected as the control group(Group B). The HR-HPV infections in women of different ages were compared, the vaginal microenvironment and the level of IL-4 in vaginal lavage fluid were detected, and the relationship between HR-HPV infection and common vaginitis was analyzed by multivariate Logistic regression analysis. Results: Among HR-HPV infected persons, the infection rate of persons ≤25 years old and >45 years old was higher than that of persons 26 to 45 years old, and the difference was statistically significant (P<0.05). There were significant differences in vaginal microenvironmental indicators and the level of IL-4 in vaginal lavage fluid between Group A and Group B(P<0.05). The positive rates of trichomonas vaginitis and bacterial vaginosis in Group A were higher than those in Group B, and the differences were statistically significant(P<0.05). Logistic regression analysis showed that Lactobacillus,trichomonas vaginitis, bacterial vaginosis, and leukocyte esterase were all independent risk factors for HR-HPV infection. Conclusion: There is age distribution characteristics in HR-HPV infection. The vaginal microenvironment and the increase of IL-4 level in vaginal lavage fluid are closely related to its classification.
