Methods: Clinical data and serum samples within 24 hours after admission were collected from 182 AP patients admitted to the emergency surgery Department of the Second Affiliated Hospital of Anhui Medical University from June 2021 to December 2022. The patients were divided into severe pancreatitis group (SAP) and Non-SAP group (Non-SAP) according to the Atlanta standard (2012). Serum biomarkers were detected by ELISA, to compare the differences of ORM2, CD5L, PCT and integrated scores. Spearman correlation analysis and Logistic regression analysis were used to analyze the correlation with the severity of the disease and the prediction probability. ROC curve was constructed to evaluate the prediction efficiency, and its differentiation and calibration were compared with Ranson, CTSI and SOFA scores. Results: Compared with the non-severe acute pancreatitis (Non-SAP) group, there were no significant differences in gender, age, systolic blood pressure and body mass index in the severe acute pancreatitis (SAP) group (P > 0.05), but Ranson, CTSI and SOFA scores and biomarkers ORM2, CD5L and PCT were significantly different (P < 0.01). Spearman analysis revealed that ORM2, CD5L and PCT were positively correlated with the severity of the disease. Logistic regression confirmed these markers as independent predictors, ROC curve showed that ORM2, CD5L, PCT and other scoring systems were important predictors of disease progression in AP patients. When the three serum indexes were combined, the area under AUC was 0.920. It is better than traditional integrated scores and single index. Conclusion: Serum ORM2, CD5L, and PCT within 24 h of admission to AP patients are of great significance for the early prediction of the severity of AP patients, and the combined prediction effect is the best.展开更多
