The publication of the National Institutes of Health Consensus Development Conference guidelines on management of Helicobacter pylori infection in 1994 set a precedence. At present, at least eight European countries have produced national guidelines, and, more recently, the European Helicobacter pylori Study Group also outlined guidelines based on the strength of available evidence. It is generally agreed that H. pylori should be eradicated in peptic ulcer disease. In nonsteroidal anti-inflammatory drug (NSAID)-related ulcers, most countries that considered the issue suggested discontinuing NSAIDs when possible and eradicating H. pylori. The prophylactic eradication of H. pylori was not recommended. A number of panels felt that there was not enough evidence available to recommend eradication of H. pylori in functional dyspepsia, whereas other groups felt that nonulcer dyspepsia, particularly after investigation and with severe or recurrent symptoms, was an indication for eradication therapy. Other conditions (i.e., gastroesophageal reflux disease [GERD] and mucosa-associated lymphoid tissue [MALT] lymphoma) have emerged in this short time as possible indications for H. pylori eradication. There is no evidence that H. pylori infection has a role in the pathogenesis of GERD, but there is evidence suggesting that patients with H. pylori infection who require long-term acid suppression may be at risk of developing atrophic gastritis. The European Helicobacter pylori Study Group has suggested that eradication therapy should be offered to infected family members of patients with gastric cancer. It also recommended that eradication therapy was “strongly recommended” on the basis of “supportive” evidence in gastritis with severe abnormalities and after early resection of early gastric cancer. An “uncertain” recommendation with “equivocal” evidence was given for asymptomatic subjects, extra-alimentary tract disease, the prevention of gastric cancer in the absence of risk factors, and in pediatric patients with recurrent abdominal pain. Despite considerable advances, further research studies are needed to provide definite direction for the treatment of many conditions.
