Abstract
ABSTRACT To investigate the clinical value of methylation levels of peripheral blood DDR1 and CtBP genes in evaluating the severity of acute pancreatitis (AP). Collect 90 blood samples from AP patients and healthy volunteers, and test methylation levels of SPINK1, STAT3, KIT, CFTR, DDR1, CtBP1, CtBP2 genes by bisulfite amplicon sequencing (BSAS). The gene methylation and clinical predictors of SAP early prediction were determined by univariate and multifactorial analysis, respectively. (1) The methylation level of CtBP1 gene and MCTSI score were independent predictors of SAP, with AUC values of 0.723 and 0.8895, respectively. (2) The methylation levels of DDR1, CtBP2, CFTR and SPINK1 genes were statistically significant in HC group vs AP group, HC group vs MAP group, and HC group vs SAP group. (3) The combined detection of CtBP1 gene methylation level and MCTSI score predicted the sensitivity, specificity, AUC, and 95%CI of SAP were 0.750, 0.957, 0.902, and 0.816–0.989, respectively. (1) The methylation level of CtBP1 gene in peripheral blood is an independent risk factor for predicting SAP and is a potentially good predictor of SAP, and the combined testing with the MCTSI score does not further significantly improve the early predictive value for SAP. (2) The methylation levels of DDR1, SPINK1, CtBP2, and CFTR genes were potential indicators for recognizing AP.
