  • Title: Gastric secretory abnormalities in duodenal ulcer: primary or secondary to Helicobacter pylori infection?
    Author: Lamers CB.
    Journal: Scand J Gastroenterol Suppl; 1992; 194():99-103. PubMed ID: 1298057.
    Abstract:
    Hypersecretion of gastric acid, gastrin, and pepsinogen are considered to be causally related to duodenal ulcer diathesis. Until recently, these abnormalities have been considered to be primary and largely genetically determined. However, Helicobacter pylori infection has been shown to be responsible for several of the abnormalities of gastric secretion in duodenal ulcer. H. pylori infection is not only associated with chronic active inflammation but also with a reduction of somatostatin producing D-cells and somatostatin concentrations in the gastric mucosa. The reduced inhibitory action of somatostatin on the secretion of gastric acid, gastrin, and pepsinogen may be responsible for the hypersecretory state of the stomach in duodenal ulcer. These recent findings have drastically changed our understanding of the pathogenesis of duodenal ulcer.
