Copeptin predicted in-hospital mortality (hazard ratio [HR] 1.005), with greater than 60.1 pmol/L as the optimal cutoff (P = .0005). Copeptin (HR 1.005; P = .02), N-terminal prohormone of brain natriuretic peptide (HR 1.004; P = .031), and comorbidity burden (HR 1.207; P = .009) predicted 6-month mortality, with copeptin greater than 13.6 pmol/L indicating a more than 4-fold risk (HR 4.507; P = .0001).</p><p><strong>Conclusion: </strong>Measuring copeptin on ED admission in hypotonic hyponatremia aids diagnosis and mortality prediction. The copeptin/u-Na index more accurately identifies preserved ECF than the standard u-Na cutoff.</p>","PeriodicalId":50238,"journal":{"name":"Journal of Clinical Endocrinology & Metabolism","volume":" ","pages":"e3952-e3961"},"PeriodicalIF":5.1,"publicationDate":"2025-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12623048/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143994018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
