Review article:: non-steroidal anti-inflammatory drugs and Helicobacter pylori

Non-steroidal anti-inflammatory drugs (NSAIDs) and Helicobacter pylori are well-recognized causes of gastroduodenal mucosal damage. This damage is mediated through the effects of both agents on acid secretion, neutrophil activity and function, and prostaglandin metabolism. Clinical trials on the interrelationship between H. pylori, NSAIDs and gastroduodenal mucosal injury have yielded conflicting results. No consensus has been reached on what recommendations should be implemented with regard to H. pylori eradication in patients on long-term NSAID therapy. At present, the presence of H. pylori is identified at endoscopy and eradication is carried out in symptomatic patients. Asymptomatic patients remain a dilemma that requires further investigation. Clinical practice will continue to be tailored to a patient's individual requirements. Therefore, in patients at risk of gastrointestinal haemorrhage, and on NSAID therapy, acid suppression therapy should be prescribed.
