Abstract

Introduction: Eradication rates of many therapeutic regimens for Helicobacter pylori (H. pylori) infection are not yet satisfactorily, mainly due to bacterial resistance to antibiotics, and to a limited availability of antibiotics in children.

Materials and Methods: Fifty-three children with H. pylori infection were prospectively enrolled, characterized by clinic, endoscopic findings and antibiotic resistance and treated with sequential therapy (ST cohort); this cohort was compared with an historic cohort of 106 children treated with standard triple therapy (TT cohort). The eradication rate of the two treatments was obtained, based on antibiotic resistance towards amoxicillin (AMO), metronidazole (MET), and clarithromycin (CLA).

Results: In the ST cohort: 27 patients (51%) resulted susceptible towards antibiotics; the eradication rate was of 88.7% (47/53 patients) overall, and of 84.6% (22/26 patients) among patients with resistance. In the TT cohort: 53 (50%) resulted susceptible towards antibiotics; the eradication rate was of 87.7% (93/106 patients) overall, and of 79.2% (42/53 patients) among patients with resistance. The two cohorts had a similar overall eradication rate (p value 0.23), while the eradication rate in patients with resistance was significantly higher for the ST cohort (p value 0.04).

Conclusion: Sequential regimen could be a valid option to eradicate H. pylori infection, especially in case of antimicrobial resistance.
