Amylasemia in uremics: a complex interpretation

Plasmatic amylase increases quite often in uremia. Hyperparathyroidism is also present in uremic patients and it is thought to be the main factor of an increased of amylase; its effect is mediated by an increase of cytosolic calcium. The authors measured the plasmatic level of amylase, lipase, calcium phosphates and parathormone before and after administration of Ca-antagonists (Verapamil and Diltiazem). The results did not shown any correlation. Hyperparathyroidism increased the pancreatic secretion but don't influences the amount of enzymes.
