RESUMEN
In two London hospitals during five months in 1997, among patients referred for esophago-gastroduodenoscopy, 250 complained of dyspepsia for more than two days per week. Of these, 190 gave informed consent to enter a study of H. pylori infection in nonulcer dyspepsia, but only 42 (22%) were found to have H. pylori infection without a peptic ulcer. At the time of this interim report, of these patients, 26 had been treated with omeprazole, amoxicillin, and clarithromycin, four weeks had elapsed since treatment, and H. pylori had been eradicated. Of these 26 patients, 15 (58%) had lost nearly all their symptoms. This is the first report of loss of symptoms in patients with nonulcer dyspepsia after treatment with omeprazole, amoxicillin and clarithromycin with early follow-up after four weeks. However, this was not a placebo-controlled study and the number of patients was small, so it is not possible to conclude whether H. pylori could be one cause of nonulcer dyspepsia. The increasing incidence of posteradication esophagitis is discussed as is the possible need for more sophisticated management of nonulcer dyspepsia.
