Popis: Background: the previous intake of macrolide antibiotics is associated with a failure to eradicate Helicobacter pylori (H. pylori) with clarithromycin-containing regimens. However, the standard triple therapy achieves eradication rates of over 90% in patients without a previous use of macrolides in our health area. The aim of this study was to evaluate the efficacy of an H. pylori eradication strategy based on the intake of macrolides by the patient during the previous years. Methods: one hundred and sixty-nine patients with H. pylori infection were prospectively included in the study. The electronic medical record of each patient was reviewed at the time of inclusion. Depending on their previous intake of macrolides, patients were assigned to one of two eradication regimens: group A) patients without a previous intake of macrolides received an optimized triple therapy for 14 days; and group B) patients with a previous intake of macrolides received bismuth quadruple therapy for ten days. Results: ninety-one patients (53.84%) without a previous intake of macrolides received an optimized triple therapy (group A) and 78 patients (46.15%) with a previous intake of macrolides received bismuth quadruple therapy (group B). In group A, the H. pylori eradication rates were 90.11% in the intention-to-treat and 95.35% in the per-protocol analysis. In group B, the H. pylori eradication rates were 85.89% in the intention-to-treat and 98.5% in the per-protocol analysis. The overall eradication rates obtained using this strategy were 88.16% (95% CI: 82.32-92.02%) in the intention-to-treat and 96.75% (95% CI: 92.59-98.94%) in the per-protocol analysis. Conclusions: an H. pylori eradication strategy based on the intake of macrolides during the previous years achieves overall eradication rates close to 90% and allows the use of standard triple therapy in more than half of the patients from a health area with a high level of clarithromycin resistance.
