Abstract

BACKGROUND AND OBJECTIVE:

The Helicobacter pylori eradication in patients with functional dyspepsia has been the subject of controversy because trials come to contradictory conclusions. The objective of this trial was to evaluate the effect, compared with placebo, of the eradication treatment in patients with functional dyspepsia.

PATIENTS AND METHOD:

Randomized double blind placebo controlled trial. We included 158 patients attended by family physicians (Area 10 Primary Care, Health Institute of Madrid) with functional dyspepsia and Helicobacter pylori infection detected by the ureasa test in endoscopy. An OCA (ameprazole clarithromycin and amoxicillin group (n = 79) and a placebo group (n = 79) were randomized. During 7 days, patients at the OCA group received omeprazole (20 mg bid), clarithromycin (500 mg bid) and amoxicillin (1000 mg bid) daily, and patients at the control group received the placebo agent twice daily. Dyspepsia improvement according to a Likert scale (5 steps), and eradication of H. pylori by 13C-urea breath test were evaluated during one year.

RESULTS:

Both groups were homogeneous in relation to age, sex and dyspepsia degree. The average age (standard deviation) of studied patients was 41.99 (13.93) years. At one year of follow up, H. pylori was eradicated in 81.01% (64/79) of the OCA group and 5.06% (4/79) of the placebo group. The difference of dyspepsia improvement (22.78%; 95% confidence interval [CI], 7.62-37.79) between the OCA group (41.77%; 95% CI, 30.77-53.41), and the placebo group (18.99%; 95% CI 11.03-29.38) was significant (p = 0.0018).

CONCLUSION:

Eradication of Helicobacter pylori in patients with functional dyspepsia is more effective improving symptoms than placebo.
