OBJECTIVES: First-line standard eradication efficacy with lansoprazole, amoxicillin and clarithromycin regressed over 10 years. The aim of this study was to evaluate the efficacy and tolerability of a levofloxacin-based regimen in patients with peptic ulcer after failure of the standard first-line H.pylori eradication therapy in a country with a high rate of infection. METHODS: A total of 91 peptic ulcer patients who were diagnosed H.pylori positive proven by rapid urease test and histology between November 2005 to March 2008 were given lansoprazole 30 mg bid, amoxicillin 1 g bid and clarithromycin 500 mg bid (LAC) for 14 days. After three months from the first line eradication treatment omeprazole 20 mg bid, levofloxacin 500 mg bid, amoxicillin 1 g bid (OLA) 7 day treatment regimen was recommended as a second-line therapy for 37 patients who failed at first-line standard triple therapy. RESULTS: Eradication rates for LAC regimen were found to be 57.14% (52/91) for intention to treat and 58.42% (52/89) for per protocol analysis. Eradication rates for OLA regimen were found to be 37.83% (14/37) for ITT and 41.17% (14/34) for PP analysis. CONCLUSION: OLA regimen eradication rate was successful only in 40% of patients who failed in the first-line eradication. New eradication treatment strategies must be performed, at least in Turkey.
