Soluble urokinase-type plasminogen activator receptor (suPAR) is a glycoprotein secreted during inflammation and infections. Moreover, increased levels of suPAR are observed after hypoxia and ischaemia. The aim of the study was to assess whether suPAR could represent a useful marker of acute pancreatitis (AP) severity.Patients and methodsWe have observed a cohort of 126 prospectively enrolled patients. Based on the presence of persistent organ failure (more than 48 h) and local complications (diagnosis of moderate AP [MSAP]), patients were classified into three groups: mild AP (MAP), moderate and severe AP (SAP). The blood samples were taken on admission for detecting suPAR concentrations.ResultsAP was considered severe in 33 patients (26.2%), MSAP was found in 37 patients (29.4%), and MAP was found in 56 patients (44,4%). The AUC for SAP predicted by suPAR was 0.993. The calculated cut-off point for prognosis SAP is 4.75 ng/mL. The BISAP score of ≥3 for detection of SAP had sensitivity and specificity of 94.6% and 63.6%, respectively. The AUC for severity predicted by BISAP amounted to 0.916. Additionally, suPAR turned out to be a good predictor of fatal AP: for the cut-off point 7.05 ng/mL, the AUC was 0.917. The AUC for death prediction in AP patients based on the BISAP score ≥3 was 0.894.ConclusionssuPAR concentration is a promising new diagnostic and prognostic indicator in SAP obtainable in the early stage of disease. Larger studies are recommended to evaluate this role further.
