In order to evaluate the renal metabolism of amylase and immunoreactive trypsin (IRT) in chronic pancreatic disease, we assayed amylase, IRT and creatinine in serum and urine and gamma-glutamyl transferase (GGT) in dialyzed urine as well as alpha-glucosidase (AGL) and ribonuclease (RNase) in 24 control subjects, 34 patients with pancreatic cancer, 52 with chronic pancreatitis and 32 with extra-pancreatic diseases. Urinary amylase and IRT outputs were found to be more elevated in chronic pancreatitis than in control subjects. The levels of serum amylase, its renal inputs and outputs were correlated with the corresponding IRT values. Multiple regression analyses (dependent on amylase or IRT urinary outputs, circulating levels of the two enzymes, creatinine clearance and the excretion of GGT, AGL and RNase predictor variables) showed significant correlations. The standardized partial regression coefficients found to be significant were: GGT, RNase and serum amylase for amylase, and GGT and RNase for IRT. No difference was found between amylase and IRT outputs in patients with chronic pancreatitis, taking the presence or the absence of alcohol abuse, exocrine insufficiency and pancreatic pseudocysts into consideration. Urinary GGT excretion correlated with serum amylase and IRT levels.(ABSTRACT TRUNCATED AT 250 WORDS)
