Abstract

In this study, 6 infants with type 1 retinopathy of prematurity (ROP) were compared with 4 high-risk preterm neonates without any ROP but similar baseline neonatal comorbidities. The infants with type-1 ROP showed significant enrichment of Enterobacteriaceae at 28 weeks' postmenstrual age. Several metabolic pathways, including several amino acid metabolism pathways, were enriched in gut microbiota of infants without ROP. Based on these findings, we posit a possible association between early gut microbiome profile and ROP pathogenesis. Furthermore, it is possible that absence of Enterobacteriaceae overabundance, in addition to enrichment of amino acid biosynthesis pathways, may protect against severe ROP in high-risk preterm infants.

摘要

在这项研究中,将 6 名患有 1 型早产儿视网膜病变(ROP)的婴儿与 4 名患有相似基线新生儿合并症但无任何 ROP 的高危早产儿进行了比较。患有 1 型 ROP 的婴儿在 28 周龄时表现出肠杆菌科的显著富集。在没有 ROP 的婴儿的肠道微生物群中,包括几种氨基酸代谢途径在内的几种代谢途径都得到了富集。基于这些发现,我们假设早期肠道微生物组特征与 ROP 发病机制之间可能存在关联。此外,除了氨基酸生物合成途径的富集外,肠杆菌科的过度生长缺失也可能保护高危早产儿免受严重 ROP 的侵害。
