Effect of Helicobacter pylori eradication on antral somatostatin cell density in humans

Abstract

Following eradication of H. pylori, there is an increase in somatostatin cell density with a fall in plasma gastrin. This supports the theory that H. pylori infection results in a decrease in somatostatin cell density and, as the latter is an inhibitor of gastrin cells, this results in an increased plasma gastrin.
