Background/Aims
Early assessment is a key factor for adequate and comprehensive treatment of acute pancreatitis (AP). Silent information regulator 1 (SIRT1) plays an important role in inflammation. The aim was to explore the relationship between serum SIRT1 and persistent organ failure (POF) in patients with AP.
Methods
Thirty-seven healthy controls (HCs) and 113 patients with AP were recruited for this study. All 113 patients whose blood samples were collected on the first morning after admission were within 48 h of the onset of AP symptoms. The concentration of serum SIRT1 protein was determined by enzyme-linked immunosorbent assay.
Results
The serum SIRT1 protein levels were 1495.7 ± 185.9, 2098.3 ± 153.6, 2498.4 ± 198.2, and 3674.3 ± 170.8 pg/ml in the HCs, mild AP, moderately severe AP, and severe AP groups, respectively. Obvious differences were observed between HCs and patients with AP (P < 0.05). Significant increases were observed in SIRT1 concentrations in patients with POF compared with non-POF patients (P < 0.05). When the cut-off of the SIRT1 concentration was 4065.4 pg/ml, the serum SIRT1 concentration had an area under the curve (AUC) of the receiver operating characteristic curve of 0.825 (95% CI 0.744–0.906) for predicting POF, with a sensitivity of 61.4% and specificity of 92.8%. Combining serum SIRT1 and bedside index for severity acute pancreatitis (BISAP) achieved 0.931 (95% CI 0.882, 0.980) of AUC for the predication of POF.
Conclusions
High serum SIRT1 levels may serve as an early predictive marker for POF. Combining the serum SIRT1 concentration with BISAP increased the ability to predict outcomes.
