研究目的: |
基于阴道微生态特征分型能否作为孕激素预防早产精准用药转型的一个突破口?目前尚未见相关报道。我们前期研究提示:孕中期流产史孕妇若孕16周前阴道菌群为高危型乳酸杆菌型,或孕中期短宫颈孕妇若加德纳尔菌属和普雷沃菌属占比高,均使自发性早产风险显著增加。最新发表在Nature Microbiology杂志上的一项阴道微生物代谢组学研究,发现:在孕激素栓剂预防早产的孕妇中,阴道菌群代谢物(包括二乙醇胺和乙基葡萄糖苷)与随后的早产事件之间存在相关性。这提示在使用孕激素预防早产时,阴道菌群通过代谢产物参与预防早产的作用。鉴于当前临床实践中的经验性使用孕激素预防早产效果欠佳,加之大量研究证实孕16周前阴道微生态与自发性早产之间存在密切关联,本研究拟基于前期研究的基础上,以阴道菌群为分型主要依据,深入挖掘阴道菌群在指导孕激素精准用药方面的潜能,开发基于阴道菌群特征识别的孕激素精准用药决策工具,为临床实践提供优化措施。 |

Objectives of Study: |
Can vaginal microecological typing serve as a breakthrough for the transformation of precision progesterone therapy for preterm birth prevention? There are currently no relevant reports. Our previous research suggests that pregnant women with a history of mid-trimester miscarriage whose vaginal flora is of the high-risk lactobacillus type before 16 weeks of gestation, or pregnant women with a short cervix in mid-trimester whose vaginal flora is of the high proportion of Gardnerella and Prevotella species, have a significantly increased risk of spontaneous preterm birth. A recent vaginal microbiome metabolomics study published in Nature Microbiology found that in pregnant women who used progesterone suppositories to prevent preterm birth, there was a correlation between vaginal flora metabolites (including diethanolamine and ethyl glucoside) and subsequent preterm birth events. This suggests that when using progesterone to prevent preterm birth, vaginal flora participate in the prevention of preterm birth through metabolites. Given the unsatisfactory efficacy of empirical progesterone use in current clinical practice for preventing preterm birth, and considering the extensive research confirming a close association between vaginal microecology before 16 weeks of gestation and spontaneous preterm birth, this study aims to build upon previous research, using vaginal flora as the primary classification basis, to further explore the potential of vaginal flora in guiding preci |
