Present-day concepts on gastric pathology in patients with chronic renal failure.

Patients with chronic renal failure often reveal a peculiar "uremic gastropathy" characterized by a decreased secretory activity of the gastric glands. Most of such patients should not be referred to the group of high risk of ulceration. This point is extremely important, when cases are screened for kidney transplantation. Immunomorphological changes occurring in the gastric mucosa provide just one of the possible etiological factors, which also include uremic intoxication and, probably, the intragastric effect of nitrous metabolic products. A long-term (months) therapy by programmed hemodialysis is not, as a rule, accompanied by the development of gastric hyperchlorhydria and hypersecretion.
