Pathophysiology of duodenal ulcer disease.

Abstract:

:Before the discovery of Helicobacter pylori infection some 12 years ago, three major disturbances in gastric physiology had been identified in patients with duodenal ulcer disease. These abnormalities were: impaired acid inhibition of gastrin release from the antral mucosa, increased basal and stimulated acid secretion by the body of the stomach and increased acid load in the duodenum. Some of these abnormalities in gastric function can now be explained by the effects of H. pylori infection. The increased release of gastrin by the antral mucosa in duodenal ulcer patients, for example, can be entirely explained by the effects of this organism. Other abnormalities, however, appear to have a genetic basis or may be due to environmental factors. Much work has been conducted on the relationship between H. pylori and the development of duodenal ulcer disease and this paper aims to review recent studies in the field and to give an overview of the latest understanding of the pathophysiology of this disease.
