Gastrin and gastric acid secretion in renal failure

American Journal of Surgery
R I WesdorpJ E Fischer

Abstract

In 10 anephric patients awaiting transplantation, 15 patients with chronic renal failure and 30 patients with acute renal failure, daily basal plasma gastrin levels and basal and stimulated gastric acid secretion were measured. Significant elevated plasma gastrin levels were found in all of the anephric patients and in 50 percent of the patients with acute and 55 percent of those with chronic renal failure. Elevated plasma gastrin levels decreased to normal after kidney transplantation or when kidney function returned to normal in the patients with acute renal failure. Gastric acid secretion studies showed a consistent pattern in all three groups of patients with a low basal acid output, a high basal intragastric pH and a very significant peak acid output, perhaps secondary to elevated plasma gastrin levels due to inadequate renal inactivation of gastrin. This may partly explain the increased incidence of gastrointestinal bleeding and gastritis seen in patients with different degrees of renal failure.

Atrophic Gastritis

Atrophic Gastritis is a process where gastric glandular cells are lost and replaced with firbous tissues, as a result of chronic inflammation. Learn more about Atrophic Gastritis here.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
