Background. We investigated whether addition of bismuth subcitrate (BSC, 4 × 120 mg) to a two week therapy scheme of omeprazole (OME, 2 × 40 mg)/amoxicillin (AMO, 4 × 500 mg) increases Helicobacter pylori eradication. Materials and Methods. Patients with dyspepsia underwent upper endoscopy. H. pylori positive patients were randomized to treatment A (OME/AMO, 83 patients) or treatment B (OME/AMO/BSC, 84 patients). Results. In 65 patients of group A (78%) H. pylori was eradicated as determined from the histological assessment (Sydney classification) of antrum and corpus biopsies. In comparison, in 68 patients of group B (81%) H. pylori was eradicated ( p = NS between groups). H. pylori eradication in both groups was associated similarly with a decrease of inflammation and activity whereas atrophy and intestinal metaplasia were not affected. A positive association was revealed between the decrease of H. pylori score and the decrease of both inflammation and activity scores for antrum as well as corpus biopsies. Conclusions. Addition of BSC to OME/AMO does not increase H. pylori eradication in patients with dyspepsia. Eradication of H. pylori is associated with disappearance of epithelial damage (inflammation and activity) in antral and corpus mucosa.
