title: Helicobacter pylori eradication in patients with non-ulcer dyspepsia.
abstract: Epidemiological and pathophysiological studies, as well as clinical trials, attempting to identify a relationship between Helicobacter pylori infection and non-ulcer dyspepsia (NUD), or a subset of NUD, have produced inconsistent and confusing results. While it is possible that H. pylori eradication may be beneficial for symptom relief in a small proportion of patients, routine H. pylori testing and treatment in documented NUD is not currently widely accepted. Despite the lack of convincing evidence, the European Helicobacter pylori Study Group, an Asian Pacific Consensus Meeting, the American Digestive Health Foundation and the American Gastroenterology Association have all recommended considering H. pylori eradication in patients with NUD on a patient-by-patient basis. Recently, large prospective, randomised, double-blind, controlled clinical trials applying highly effective antimicrobial therapy have been conducted with 12 months follow-up. Although these well-designed studies have reached differing conclusions, the results have been largely negative. H. pylori eradication therapy in NUD will fail to relieve symptoms in most patients in the long term.
