In the validation phase, 2 of these 5 lncRNAs—SNHG5 and ZFAS1—showed significant expression differences between cachectic and noncachectic patients in the entire study group (both <em>P</em> &lt; 0.001). The combined downregulation of ZFAS1 and upregulation of SNHG5 was identified as an unfavorable lncRNA signature primarily associated with poor nutritional status in females (low fat-free mass, fat-free mass index, and body mass index), abnormal laboratory results (hypoalbuminemia and high concentrations of inflammatory markers), and an increased incidence of cachexia in patients with CHF. When this lncRNA signature was combined with serum C-reactive protein and albumin concentrations, it effectively differentiated between cachectic and noncachectic patients (area under the curve = 1.0). The presence of this unfavorable signature was associated with a 9-fold increased likelihood (odds ratio = 9.2) of cachexia in the study cohort.</div></div><div><h3>Conclusions</h3><div>The identified lncRNA signature demonstrates potential clinical value for distinguishing and predicting cachexia in patients with CHF.</div></div>","PeriodicalId":16620,"journal":{"name":"Journal of Nutrition","volume":"155 3","pages":"Pages 817-825"},"PeriodicalIF":3.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143029104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
