title: [Dyspepsia and Helicobacter (Campylobacter) pylori. Results of a randomized therapeutic trial using amoxicillin versus placebos].
abstract: A population of non ulcer dyspepsia outpatients with a normal gastroscopy was assessed. Clinical complaints, the type of the gastritis, its activity and bacterial density were evaluated. Helicobacter pylori (HP) was sought by histology, urease test and culture, on 3 distinct locations. HP was found in 62 p. cent of the patients, always in association with gastritis. Urease test and histology had the same sensitivity in the detection of HP. A randomized double blind study with amoxicillin vs placebo was carried out in 23 patients. At the end of 4 week treatment, a gastroscopy with biopsies was performed. The amoxicillin treated patients were significantly cured or improved. HP was undetectable or the bacterial density was decreased in this group. After amoxicillin, urease test was more sensitive than histology. HP might be involved in the pathophysiology of non ulcer dyspepsia in patients where HP was found.
