Clinical value of plasma presepsin level in early severity evaluation for acute pancreatitis patients / 中华胰腺病杂志

ABSTRACT

Objective:To investigate the clinical value of plasma presepsin level in early severity evaluation for acute pancreatitis (AP) patients.Methods:The clinical data of 67 patients with AP admitted in Second Affiliated Hospital of Wenzhou Medical University from December 2016 to January 2019 were prospectively selected. The patients were divided into mild AP group (MAP, n=36) and moderately severe and severe AP group (MSAP+ SAP, n=31) according to CTSI and with or without organ dysfunction and local or systemic complications on admission. Another 20 healthy normal subjects were selected as the control group. Plasma presepsin, C-reactive protein (CRP), procalcitonin (PCT), white blood cell count (WBC), serum amylase and calcium levels were measured within 2 hours, and the APACHEⅡ score was calculated within 24 hours of admission. Receiver operating characteristic curves(ROC) were plotted and the area under the curve (AUC) was calculated to assess the clinical value of presepsin, CRP, PCT, WBC, serum amylase and calcium for predicting the severity of AP patients, respectively. Results:The plasma presepsin level in MAP, MSAP+ SAP and control group was (439.59±74.23)ng/L, (1097.82±93.15)ng/L and (97.31±21.57)ng/L, respectively. Plasma presepsin level in MAP and MSAP+ SAP patients with biliary pancreatitis were obviously higher than those patients with other etiological factors, and plasma presepsin level in MSAP+ SAP patients with hyperlipidemia-associated pancreatitis was significantly higher than those in the MAP group, and the difference was statistically significant ( P<0.05). The AUC of plasma presepsin in the diagnosis of MSAP+ SAP was 0.873(95% CI 0.734-0.922), which was greater than the AUC values of CRP, PCT, WBC and serum calcium; the optimal cut-off value was 951.94 ng/L; the diagnostic sensitivity was 85.6%, which was superior to CRP, PCT, WBC and serum calcium; and the specificity was 76.2%, which was second to 78.9% of serum calcium. Conclusions:Plasma presepsin level can be used as a sensitive indicator for early severity evaluation of AP patients, with a specificity only second to serum calcium.
