Area under the curves for Cmi ranged from 0.88 to 0.90, which was statistically superior to area under the curves of Acute Physiology and Chronic Health Examination-II and bedside index for severity in AP, and outperformed blood urea nitrogen and creatinine in POF prediction across all cohorts ( P < 0.05). Higher levels of Cmi indicated an increased need for intensive care unit admission, prolonged hospitalization, and elevated mortality rate, thus poor prognosis. In the nested case-control study, Cmi could help identify prediagnostic POF in postendoscopic retrograde cholangiopancreatography pancreatitis cases within \"golden hours\" after endoscopic retrograde cholangiopancreatography with high efficacy.</p><p><strong>Conclusions: </strong>Serum exosomal Cmi may be an early predictor for POF in AP, even within \"golden hours\" after AP onset.</p><p><strong>Trail registration: </strong>ClinicalTrials.gov (NCT02602808).</p>","PeriodicalId":8017,"journal":{"name":"Annals of surgery","volume":" ","pages":"93-99"},"PeriodicalIF":7.5,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139696837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
