Association of IL-17 and IL-23 Gene Variants with Plasma Levels and Risk of Vulvovaginal Candidiasis in a Chinese Han Population.

ABSTRACT:

Background

Vulvovaginal candidiasis (VVC) is a common vaginal inflammatory disease in females. The interleukin (IL)-23/IL-17 axis was involved in vaginal inflammation. Nevertheless, the relationship between gene polymorphisms in the IL-23/IL-17 axis and VVC risk is still unexplored.

Methods

We enrolled 217 VCC cases and 326 controls in this study. The genotyping of all polymorphisms was implemented by PCR-RFLP methods.

Results

Data indicated that IL-17F gene rs763780, IL-17A gene rs2275913, and IL-23R rs11209026 polymorphisms were linked with an elevated risk of VVC in Chinese ethnicity. Subgroup analyses uncovered that IL-23R rs11209026, IL-17A rs10484879 and IL-17F rs763780 polymorphisms increased the risk of VVC among smokers or individuals with BMI ?25 kg/m². Additionally, IL-17F rs763780 polymorphism was shown to increase the risk of recurrent VVC (RVVC). Furthermore, IL-23 and IL-17 serum levels were higher among VVC cases than controls. We also observed that IL-23 and IL-17 gene polymorphisms were related to their serum levels. Receiver operating characteristics (ROC) curve analysis found that IL-17 and IL-23 serum levels were associated with the relapse of VVC.

Conclusion

In conclusion, this study indicates that polymorphisms in the IL-23/IL-17 axis increase the risk of VVC.
