Helicobacter pylori in 1997

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.
