ABSTRACT
Objective:To investigate the pathogenic factors of vulvovaginal candidiasis (VVC) in occupational women of childbearing age and the prognostic value of interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α) and interleukin (IL)-2.Methods:184 patients from the Meishan Maternal and Child Health Hospital from June 2016 to June 2017 in the gynaecological clinic were selected for research.The self-made general situation questionnaire was used to investigate the situation of the patients, and the vaginal secretions of the patients were sampled for microscopic examination to diagnose vulvovaginal candidiasis. According to the prevalence and recurrence of VVC, the patients were divided into recurrent group (42 cases), non recurrent group (55 cases) and non-VVC group (87 cases). Single factor analysis and multi factor logistic analysis were used to analyze the pathogenic factors of VVC.Results:Among the 184 patients, 97 were diagnosed as VVC, with a 52.72% incidence rate. The results of single analysis showed that age, drinking sugary drinks, eating sweets, exercising, sedentary, emotional state, frequency of using pads in non menstrual period, wearing tights, history of vaginitis, frequency of vaginal washing, history of curettage, contraceptive method, first sexual intercourse age, number of sexual partners, whether washing vulva before and after sexual life were related to the incidence of vulvovaginal candidiasis in occupational women of childbearing age ( P<0.05). The results of multivariate analysis showed that sedentary, drinking sugary drinks, eating sweets, wearing tights, vaginal washing frequency, first sexual intercourse age, contraceptive method, number of sexual partners, history of curettage, history of vaginitis, and cleaning vulva before and after sexual life were all independent factors ( P<0.05). There was no significant difference in TNF-α level among the three groups ( P>0.05), while the IFN-γ and IL-2 levels were the lowest in the recurrent group, the second in the non recurrent group, and the highest in the control group ( P<0.05). Conclusions:The incidence rate of VVC in the women of childbearing age occupation is related to sedentary, sugar drinking, sweet food, tight pants frequency, vaginal irrigation frequency, first sex, contraceptive methods, sexual partners, curettage history, vaginitis history, sexual cleansing before and after sexual activity. Clinically, relevant factors can be intervened to reduce the incidence of the disease. The decrease of IFN-γ and IL-2 may increase the risk of VVC.
