摘要: 目的 探讨阴道微生物(vaginal microbiota, VMB)组成与人乳头瘤病毒(human papilloma virus, HPV) 16型和18型感染的关系。方法 采用基因二代测序方法测定阴道微生物16S rRNA 基因及聚合酶链反应技术(polymerase chain reaction,PCR) 进行HPV 16型、18型核酸测定。采用χ2检验及Logistic 回归分析阴道微生物菌群构成类型(community state types,CSTs)与HPV-16型和18型感染的相关性, UniFrac加权矩阵及LEfSe线性分析特定微生物菌群与HPV-16型和18型感染的相关性。结果 本研究中共发现3种阴道微生物菌群构成类型,分别是CST IV(low Lactobacillus spp.) 65.4%,CST Ⅲ(L. iners) 32.1%和CST V(L. jensenii) 2.6%,LEfSe分析显示HPV16感染者阴道微生物乳酸杆菌缺乏而厌氧菌属丰富,无乳链球菌(Streptococcus agalactiae)仅发现于HPV16感染者阴道微生物菌群中。HPV18感染者阴道微生物菌群以乳酸杆菌属(Lactobacillus)为主要丰度,而缺乏厌氧菌属。结论 阴道微生物菌群的构成及丰度与HPV16感染相关,无乳链球菌可能作为HPV16感染的标志性阴道微生物菌群,但需要进一步研究证据支持。

Abstract: Objective To evaluate the association between human papillomavirus (HPV) 16, 18 and the vaginal microbiome. Methods Totally 78 women who underwent initial HPV screening in Beijing Chaoyang Hospital between January and June in 2016 were recruited into this study. Vaginal bacterial composition was characterized by deep sequencing of barcoded 16S rRNA gene fragments (V4) on Illumina MiSeq and HPV was identified using the Shanghai ZJ Bio-tech Array © HPV genotyping test. The exact Logistic regression models were applied to evaluate the association between community state types (CSTs) of vaginal microbiota and HR-HPV infection, weighted UniFrac distances were used to compare the vaginal microbiota of individuals with prevalent HR-HPV to those without prevalent HR-HPV infection, and the Linear Discriminant Analysis effect size (LEfSe) algorithm was applied to characterize bacteria associated with prevalent HR-HPV infection. Results Three CSTs were observed:CST IV with a low relative abundance of low Lactobacillus spp. in 65.4% of participants; CST Ⅲ(dominated by L. iners) in 32.1%; CST V(dominated by L. jensenii) in 2.6%; LEfSe analysis suggested an association between the prevalent HPV-16 infection and the decreased abundance of Lactobacillus spp. with increased abundance of anaerobes particularly of the genera Streptococcus agalactiae which were only found in HPV-16 positive women (P<0.05). A predominance of Lactobacillus spp. was still present in HPV-18 positive women with depletion of strictly anaerobic species. ConclusionHPV-16 infection was associated with the composition and abundance of vaginal microflora and Streptococcus agalactiae can be the specific bacterial taxa of HPV-16 positive women, Further studies were needed to confirm these finding.
