Hormonal, secretory and morphological alterations in gastric mucosa in the course of Helicobacter pylori eradication in patients with duodenal ulcer and non-ulcer dyspepsia.

Changes in endocrine and secretory functions and in the morfology of gastric mucosa in the course of quadruple H. pylori eradication regimen in 50 H. pylori positive patients: 25 with duodenal ulcer (DU) and 25 with non ulcer dyspepsia (NUD) were studied and compared to 10 healthy controls. Therapy resulted in ulcer healing in all DU patients and in 92% eradication of H. pylori in both groups of patients-DU and NUD. In DU and NUD patients in the course of eradication significant decrease in plasma gastrin was observed. Somatostatin concentration in gastric juice increased significantly in DU patients after anti-H. pylori therapy. EGF in gastric content of DU and NUD patients has risen statistically significantly in the course of H. pylori eradication. Gastric acid output and volume flow decreased insignificantly in both groups. The elimination of H. pylori from gastric mucosa in both DU and NUD patients led to significant decrease in the density and activity of gastritis.
