目的

探索外阴阴道假丝酵母菌病(VVC)对女性阴道菌群的影响。

方法

从苏州高新区参与2018至2019年“两癌”筛查的35~65岁女性中招募本项目受试者,并采集宫颈分泌物样本以及相关表型信息,从入组的女性中,筛选出123名女性的样本进行分析,包括36名诊断为VVC的女性和87名健康女性(作为对照)。对分泌物样本进行宏基因组鸟枪法测序检测微生物菌群,并分析阴道微生态与VVC的相关性。

结果

主坐标分析(PCoA)结果显示VVC女性和健康女性阴道微生物菌群有明显差异(PermANOVA检验,P=0.003),VVC女性中惰性乳杆菌型占比明显更高(VVC组:61.11%;健康组:32.18%),但卷曲乳杆菌型差异不大(VVC组:16.67%;健康组:14.94%)。此外,VVC女性阴道中,雷沃菌属型的占比相对较少,尤其是二路普雷沃尔菌型(VVC组:0;健康组:8.05%)。进一步筛选菌群标记物,发现相对于健康女性,VVC女性阴道菌群中,惰性乳杆菌相对丰度显著增加(Q<0.05);而韦荣球菌科和Sneathia amnii相对丰度有减少的趋势(P<0.05,Q>0.05)。

结论

与健康女性相比,VVC女性阴道菌群有明显差异。阴道中高丰度的惰性乳杆菌可能与增加的VVC发病风险相关。

Objective

To explore the effect of vulvovaginal candidiasis (VVC) on the vaginal-cervical microbiome in women.

Methods

Women who participated in cervical and breast cancer screening (aged 35-65 years) were recruited from 2018 to 2019 at the Suzhou National New and Hi-tech Industrial Development Zone of Suzhou, China. Cervical samples and volunteer's information were collected. Then, 123 women among them were selected, including 36 women with VVC and 87 healthy women as controls. Metagenomic shotgun sequencing was performed on the cervical samples, and the relationship between the vaginal microbiome and VVC was then analyzed.

Results

Principal coordinate analysis (PCoA) showed that there was a significant difference in the vaginal microbiome between the healthy women and women with VVC (PERMANOVA test, P=0.003). The proportion of Lactobacillus iners-dominated microbiota was significantly higher in women with VVC (VVC group: 61.11%; controls: 32.18%), but Lactobacillus crispatus showed little difference between the two groups. In addition, the proportion of Prevotella-dominated microbiota, especially P. bivia-dominated microbiota declined in women with VVC (VVC group: 0; controls: 8.05%). Markers such as L. iners were enriched in women with VVC obviously (Q<0.05), while Veillonellaceae and Sneathia amnii decreased (P<0.05, Q>0.05).

Conclusion

Compared with healthy women, the vaginal-cervical microbiome has a remarkable difference in women with VVC, suggesting that VVC could cause an imbalance in the vaginal microbiome. High relative abundance of Lactobacillus iners can enhance the risk of VVC. The evaluation of the vaginal-cervical microbiome in women with VVC provides a basis for the diagnosis, treatment, and evaluation of prognosis of VVC.
