To determine the utility of serum amylase (AMY), lipase (Lp), pancreatic isoamylase (isoA), phospholipase A (PLA), and urine AMY in the diagnosis of acute pancreatitis, samples of serum and urine were obtained on admission and every day thereafter for 5 days from 384 patients with acute abdominal pain. Diagnostic accuracy, determined as the area under the receiver operating characteristic curve, was > 0.975 for serum AMY, Lp, isoA, and urine AMY. For each of these enzymes, a threshold value (twice to sixfold the upper limit of the reference values) offering diagnostic efficiency > 95% could be determined. In contrast, accuracy and efficiency of serum PLA were low. The profiles of these enzymes in acute pancreatitis decreased in a parallel fashion over 5 days except for PLA. We conclude that diagnostic utilities are similar for serum AMY, Lp, isoA, and urine AMY for acute pancreatitis, provided that an appropriate threshold is established.

In this study we determined the clinical accuracy of alpha2-macroglobulin, alpha-amylase, C-reactive protein, lipase, non-esterified fatty acids, pancreatic alpha-amylase and phospholipase A in the diagnosis and prognosis of acute pancreatitis in a group of patients with acute abdominal pain using receiver operator characteristic curve analysis. We investigated 59 patients with acute pancreatitis and 72 patients with extrapancreatic diseases of gastrointestinal origin. On the basis of initial enzyme activities, at cut-offs of 245 U/l for amylase, 656 U/l for lipase, and 182 U/l for pancreatic alpha-amylase, the diagnostic efficiencies were 0.993, 0.980, and 0.975, respectively. Receiver operator characteristic curve analysis showed the same diagnostic accuracies. We evaluated the accuracy of serum alpha2-macroglobulin, C-reactive protein, non-esterified fatty acids and phospholipase A for differentiation between acute necrotizing pancreatitis and acute oedematous pancreatitis. C-reactive protein had the highest prognostic accuracy of the parameters studied (the area under curve = 0.9082) and at a cut-off value of 126 mg/l, sensitivity and specificity were 0.759 and 0.912, respectively. The role of the clinical laboratory in the investigation of patients with acute pancreatitis continues to evolve and biochemical parameters are a good diagnostic and prognostic option.
