Review Article: is Helicobacter pylori relevant in the management of reflux disease?
Data on the interaction of reflux disease and Helicobacter pylori infection are limited in scope and rigour, controversial and difficult to interpret. Despite this, a framework of understanding is emerging, which is consistent with known effects on gastric acid secretion. In patients with moderate to severe H. pylori-induced corpus gastritis, eradication can increase substantially impaired gastric acid secretion sufficiently to precipitate reflux disease in people with pre-existing sub-clinical defective gastro-oesophageal competence. By contrast, reflux disease in duodenal ulcer patients probably benefits from eradication of H. pylori. There appears to be no significant impact on reflux disease from eradication in healthy subjects or individuals whose primary problem is reflux disease. Helicobacter pylori-infected reflux disease patients respond slightly better to proton pump inhibitors. These agents cause a topographic alteration of gastritis from antrum to corpus, the clinical significance of which is controversial. Many practitioners misjudge the risks and benefits of the effects of H. pylori eradication on reflux disease. Regardless of patient diagnosis, the balance is in favour of H. pylori eradication. For those in whom reflux oesophagitis development is a defined possibility, oesophagitis is mild, easily treated and most unlikely to be associated with any major risk for development of oesophageal adenocarcinoma.
