Managing dyspepsia: what do we know and what do we need to know?
OBJECTIVE
The conceptual revolution concerning the role of Helicobacter pylori in the pathogenesis of peptic ulcer disease has raised the larger question of how to integrate this new information into the management of patients with dyspepsia. The aim of this research was to critically evaluate current knowledge about dyspepsia and its management.


METHODS
Relevant articles on dyspepsia were identified from MEDLINE searches and from the bibliographies of identified articles. Studies that contained information on the prevalence of dyspepsia, endoscopic findings, and evaluations of alternative management strategies were reviewed.


RESULTS
By coupling H. pylori serological testing with clinical factors such as age and nonsteroidal antiinflammatory drug use, strategies have been developed that identify patients with organic disease. Although the use of these strategies can reduce the volume of endoscopies, their effects on dyspepsia symptoms are unknown. Computerized decision analysis models have been used to evaluate the cost-effectiveness of alternative strategies. The indirect evidence obtained from these models suggests that empiric therapy, guided by H. pylori testing, may be the preferred approach. However, the models have been hampered by the lack of information concerning dyspepsia symptoms, the primary health outcome of the majority of patients seen in primary practice settings.


CONCLUSIONS
Currently, the knowledge needed to integrate H. pylori tests and antimicrobial therapies into the management of patients with dyspepsia in primary practice settings has not been developed. A pressing need exists for a randomized controlled trial to evaluate alternative management strategies. In conducting such a trial, valid, reliable instruments for measuring dyspepsia will be needed.
