THE PREDICTIVE VALUE OF SERUM NEUTROPHIL GELATINASE-ASSOCIATED LIPOCALIN FOR ACUTE KIDNEY INJURY IN PATIENTS WITH ACUTE PANCREATITIS
Main Article Content
Abstract
Objectives: Determine the predictive value of serum NGAL concentration upon admission for acute kidney injury (AKI) in patients with acute pancreatitis. Methods: A prospective cohort study followed 239 patients diagnosed with acute pancreatitis according to the Atlanta 2012 criteria. NGAL testing and biochemical analysis at the time of hospital admission and at various other time points during the treatment process. Results: The average age of the study population was 46.07 ± 13.17 years, with a male-to-female ratio of 76.2%. 8.36% of acute pancreatitis patients had acute kidney injury. Upon admission, the median serum NGAL concentration in patients with acute pancreatitis and acute kidney injury was 529.8 (476.4-639.4) ng/ml, which was higher than the group without acute kidney injury, which was 429.8 (253.5-545.9) ng/ml, p>0.05. There was a weak correlation between serum NGAL concentration upon admission and the severity of acute pancreatitis, renal function tests, and pancreatic enzymes. Serum NGAL concentration at the time of admission shows a fairly good predictive ability for acute kidney injury in patients with acute pancreatitis (AUC=0.73) with a cutoff value of 446.97 ng/mL, sensitivity of 83.3%, and specificity of 56.4%. Conclusion: The incidence rate of acute kidney injury is 8.36%. The median serum NGAL concentration in patients with acute pancreatitis and acute kidney injury at admission was 529.8 (476.4-639.4) ng/mL. The serum NGAL concentration upon admission shows a fairly good prognostic ability for acute kidney injury in patients with acute pancreatitis (AUC=0.73) with a cutoff value of 446.97 ng/mL, sensitivity of 83.3%, and specificity of 56.4%.
