BACKGROUND: To evaluate the efficacy of a multistep strategy for Helicobacter pylori (HP) eradication.
PATIENTS AND METHOD: 151 patients, with peptic ulcer or chronic gastritis, infected by HP, treated (first-step) with omeprazole (20 mg/12 h), clarithromycin (500 mg/12 h) and amoxycillin (1 g/12 h) for a week (OCA) and second-step (first-step failures) with omeprazole (20 mg/12 h), metronidazole (500 mg/12 h), tetracyclin (500 mg/6 h) and bismuth (120 mg/6 h) for two weeks.
RESULTS: Intention-to-treat analysis, eradication was achieved with OCA in 78.1% (CI 95%: 71.6-84.7) and OMTB in 90.3% (CI 95%: 74.2-98), with an cumulative eradication rate of 96.7% (CI 95%: 92.4-98.9).
CONCLUSIONS: The efficacy of multistep strategy is high. Therapy with OMTB its a good option after failure with OCA.
