Helicobacter pylori and gastroduodenal disease

Annu Rev Med. 1992;43:135-45. doi: 10.1146/annurev.me.43.020192.001031.


Helicobacter pylori infection is now recognized as the primary cause of active chronic gastritis in humans. Most infected persons remain asymptomatic, but are at increased risk for the development of peptic ulcer disease and possibly gastric cancer. The pathogenesis of this infection is not well understood, but motility and urease activity are virulence factors in an animal model. The eradication of H. pylori infection is associated with resolution of gastritis and a decreased rate of duodenal ulcer recurrence.
