Hypertriglyceridemia-Induced Acute Pancreatitis with Normal Pancreatic Enzymes

      The diagnosis of acute pancreatitis requires 2 of the following 3 features: 1) abdominal pain consistent with acute pancreatitis; 2) serum lipase activity (or amylase activity) at least 3 times greater than the upper limit of normal; and 3) characteristic imaging findings of acute pancreatitis.

      Although normal serum amylase levels have been reported in some cases of acute pancreatitis,

      acute pancreatitis with normal serum lipase has been rarely described in the literature due to its negative predictive value of between 94% and 100%.

      Moreover, other pancreatic enzymes have not been mentioned in the previous reports of acute pancreatitis with normal serum lipase or amylase. Herein, we present a case of acute pancreatitis with normal serum amylase, lipase, trypsin, elastase-1, and phospholipase A2.
