Review article: dyspepsia: how to manage and how to treat?

Abstract

Recent guidelines for dyspepsia, defined as pain or discomfort centred in the upper abdomen, emphasize that in younger patients with no alarm features and not taking nonsteroidal anti-inflammatory drugs, testing for Helicobacter pylori and treatment of the infection if present is a standard of care. If H. pylori is not present, empirical management (e.g. acid suppression) is often prescribed. It is further recommended that if patients relapse or fail to respond to treatment then upper endoscopy be undertaken. However, these guidelines have become controversial for a number of reasons. Firstly, the prevalence of H. pylori infection is falling as is the incidence of peptic ulcer disease due to the infection. Idiopathic peptic ulcer disease is also being increasingly recognized. Furthermore, the cost-effectiveness of endoscoping treatment failures has been questioned, as the yield is low and patient management is usually not altered. Finally, it remains controversial whether the treatment of H. pylori infection in functional dyspepsia is of value, and two recent high quality meta-analyses have reached diametrically opposite conclusions. Alternative strategies, such as initially treating with acid suppression and then considering H. pylori infection in those who fail have been suggested, as has in low H. pylori prevalent regions the abandonment of a test-and-treat strategy. However, appropriate management trials of these alternative strategies in primary care are lacking. The management of patients with functional dyspepsia who fail initial antisecretory therapy is now difficult; prokinetics have fallen into some disrepute. Tricyclic antidepressants (at a low dose) may be useful in a subset, but adequate trials are lacking.
