A total of 90 patients diagnosed with NAFLD and 36 healthy subjects were recruited to participate in this study. Among them, a subgroup of 14 nonobese nonalcoholic steatohepatitis (NASH) were treated with UDCA. Demographic and serologic data were collected for all participants, while stool samples were obtained for fecal microbiome analysis using 16S sequencing. In nonobese NAFLD patients, the alpha diversity of intestinal flora decreased (Shannon index, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05), and the composition of intestinal flora changed (beta diversity, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). The abundance of 20 genera, including <jats:italic>Fusobacterium<\/jats:italic>, <jats:italic>Lachnoclostridium<\/jats:italic>, <jats:italic>Klebsiella<\/jats:italic>, etc., exhibited significant changes (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). Among them, nine species including <jats:italic>Fusobacterium<\/jats:italic>, <jats:italic>Lachnoclostridium<\/jats:italic>, <jats:italic>Klebsiella<\/jats:italic>, etc. were found to be associated with abnormal liver enzymes and glucolipid metabolic disorders. Among the 14 NASH patients treated with UDCA, improvements were observed in terms of liver enzymes, CAP values, and E values (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05), however, no improve the glucolipid metabolism. While the alpha diversity of intestinal flora did not show significant changes after UDCA treatment, there was a notable alteration in the composition of intestinal flora (beta diversity, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). Furthermore, UCDA treatment led to an improvement in the relative abundance of <jats:italic>Alistipes<\/jats:italic>, <jats:italic>Holdemanella<\/jats:italic>, <jats:italic>Gilisia<\/jats:italic>, etc. among nonobese NASH patients (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). Nonobese NAFLD patients exhibit dysbiosis of the intestinal microbiota. UDCA can ameliorate hepatic enzyme abnormalities and reduce liver fat content in nonobese NASH patients, potentially through its ability to restore intestinal microbiota balance.<\/jats:p>","DOI":"10.1002\/lipd.12410","type":"journal-article","created":{"date-parts":[[2024,9,9]],"date-time":"2024-09-09T04:12:56Z","timestamp":1725855176000},"page":"193-207","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Characteristics
