Abstract:
Objective:To investigate the difference in invasiveness between vulvovaginal candidiasis(VVC) and recurrent vulvovaginal candidiasis(RVVC) strains, and to explore the effect of strains with different secreted aspartate protease(Sap) on vaginal local immunity.
Methods:Vaginal secretions of VVC and RVVC patients were collected for fungus identification.Candida albicans(C.albicans) were taken for drug sensitivity analysis, 25 S rDNA genotyping, and detection of secreted aspartate protease(Sap) and phospholipase(Plb) activity.C.albicanswith different Sap activity were cultured with vaginal epithelial cells, and the levels of Interleukin(IL)-4, IL-8, IL-17 in cell supernatant were measured by ELISA.
Results:Sap activity of VVCC.albicanswas stronger than that of RVVC. After infection withC.albicans, the secretion of IL-4, IL-8 and IL-17 by vaginal epithelial cells was higher, and IL-8 and IL-17 appeared earlier and lasted longer.C.albicanswith strong Sap enzyme activity could stimulate vaginal epithelial cells to secrete more cytokines.
Conclusion:Except for the Sap activity, there was no significant difference in the invasiveness between VVC and RVVC strains.C.albicanscould activate the vaginal host immune response in a short time. The lower Sap activity ofC.albicansin RVVC patients may be related to the protective factors secreted by the vaginal epithelium.
