In this review Helicobacter pylori (H. pylori) infection and its relation to different diseases is presented. H. pylori doesn't cause inconvenience to most infected people, though all infected persons have chronic active gastritis. The 10 year risk of peptic ulcer for people infected with H. pylori is about 10%. Randomized double-blinded trials have shown that eradication of H. pylori can cure most patients with peptic ulcer disease. Some people infected with H. pylori develop atrophic gastritis which is a risk factor for development of gastric cancer. It is not known if H. pylori screening and eradication would have a prophylactic effect against gastric cancer. It is also unknown if persons with non-organic dyspepsia and persons in long-term treatment with proton-pump-inhibitors would benefit from H. pylori eradication.

Helicobacter pylori infected patients have increased gastrin release which shows a marked fall after cure of the infection. Recent studies indicate that inflammatory cells and cytokines play an important role in the pathogenesis of Helicobacter-associated hypergastrinemia. Views differ regarding the impact of gastrin on acid secretion. Current evidence suggests that gastrin is responsible for at least some of the increased acid secretion seen in duodenal ulcer patients.
