Clinical value of BISAP score combined with CRP and NLR in evaluating the severity of acute pancreatitis

Abstract

To investigate the clinical value of bedside index for severity in acute pancreatitis (BISAP) score combined with serum C-reactive protein (CRP) and neutrophil-to-lymphocyte ratio (NLR) in predicting the severity of early acute pancreatitis. A total of 113 patients with acute pancreatitis admitted to the Department of Gastroenterology, Second Affiliated Hospital of Nantong University from September 2019 to September 2022 were retrospectively collected and divided into mild acute pancreatitis group (51 cases), moderately severe acute pancreatitis group (32 cases) and severe acute pancreatitis group (30 cases) according to the severity of the disease. The general clinical data, laboratory test indicators, and imaging data within 72 hours were collected and compared among the 3 groups. The sensitivity, specificity, and accuracy of BISAP score, BISAP combined with CRP, BISAP combined with NLR, and BISAP combined with CRP and NLR in predicting the severity of acute pancreatitis were analyzed by receiver operating characteristic curve. 1. BISAP score (0.9608 ± 0.1119, 1.688 ± 0.1225, 2.6 ± 0.1135), CRP (74.77 ± 8.336, 142.9 ± 11.44, 187.6 ± 13.04), and NLR (8.063 ± 0.7781, 13.69 ± 1.023, 18.06 ± 1.685) increased sequentially in mild acute pancreatitis group, moderately severe acute pancreatitis group, and severe acute pancreatitis group, and the differences in BISAP score, CRP and NLR among the 3 groups were statistically significant (P < .05). BISAP score was positively correlated with CRP and NLR (R = 0.5062, 0.5247, P < .05). The area under the receiver operating characteristic curve of BISAP score, CRP, NLR, BISAP combined with NLR, and BISAP combined with CRP in predicting the severity of acute pancreatitis were 0.885, 0.814, 0.714, 0.953, respectively. The specificity and sensitivity of combined diagnosis were higher than those of BISAP score or CRP and NLR alone. BISAP score combined with CRP and NLR can effectively evaluate the severity of acute pancreatitis, and their combination has a higher predictive value for early severity assessment.
