Summary Background H. pylori eradication failures are difficult to treat and rescue therapies often consist of complex treatment regimens. Aim To determine an effective and practical rescue therapeutic strategy for H . pylori treatment failures using two consecutive regimens: first rescue therapy ‐ rabeprazole 20 mg t.d.s. and amoxicillin 1 g t.d.s. for 2 weeks and for failures a further second rescue therapy ‐ rabeprazole 20 mg b.d., levofloxacin 500 mg b.d., amoxicillin 1 g b.d. for a further 2 weeks. Methods Consecutive patients who failed the proton pump inhibitor ( PPI ) 1‐week triple therapy were recruited for the study. H . pylori status was determined by a C 13 urea breath test. Results One hundred and forty‐nine patients received the first rescue therapy . Seven were not compliant to medication/defaulted follow‐up. Eradication success‐ first rescue therapy : per protocol ( PP ) analysis‐107/142 (75.4%) (95% CI (68.3–82.4%) and intention to treat ( ITT ) analysis‐107/149 (71.8%) 95% CI (64.6–79.0%). Thirty‐one of 35 patients who failed the first rescue therapy received the second rescue therapy . All were compliant with medications. Eradication success‐ PP and ITT was 28/31 (90.3%) 95% CI (74.2–98.0%). The cumulative eradication rate using both rescue therapies: PP analysis‐ 135/138 (97.8%) 95% CI : (93.8–99.6%), ITT analysis‐ 135/149 (90.6%) 95% CI : (84.7–94.8%). Conclusions A 2‐week high dose PPI ‐amoxicillin dual therapy followed by a PPI ‐amoxicillin‐levofloxacin triple therapy were highly successful in achieving eradication in H . pylori treatment failures.
