Abstract

Urinary excretion of alpha-glucosidase (AGL), gamma-glutamyltransferase (GGT) and ribonuclease (RNase), and serum amylase and immunoreactive trypsin (IRT) were determined in 38 control subjects, 48 patients with pancreatic cancer, 77 with chronic pancreatitis and 47 with extrapancreatic diseases in order to ascertain the presence of a renal tubular damage and to investigate its etiology. A significantly increased frequency of pathological results for all urinary enzymes was documented in the various groups of patients as compared to controls. Significant correlations were detected among AGL, GGT and RNase. Considering the subjects as a whole, GGT and RNase excretions correlated with serum IRT and amylase; the two urinary enzymes were found to be higher when jaundice was present. In chronic pancreatic disease enzymuria was related to increased serum pancreatic enzymes; in extrapancreatic diseases it was associated to hyperbilirubinemia. The vast majority of patients with pancreatic cancer and elevated urinary enzymes presented hepatic metastases and/or jaundice. We can conclude that an anatomical and functional tubular impairment is detectable in some patients with chronic pancreatic and extrapancreatic diseases. Tubular damage seems to least in part to be related to pancreatic inflammation and necrosis in chronic pancreatic disease, while jaundice may be found to play an important role in diseases of the hepatobiliary tract. In pancreatic cancer, liver dysfunction (presence of liver metastases and/or extrahepatic cholestasis) also appears to be involved in altering tubular cells.
