What’s the best secondary treatment for patients who fail initial triple therapy for H pylori?

Two secondary antibiotic regimens show similar cure rates

A meta-analysis of 4 RCTs (total 460 patients) that compared susceptibility-guided antibiotic secondary treatment (SGT) with empiric antibiotic secondary treatment found no difference in cure rates, although the largest single RCT (172 patients) favored SGT.⁴

RECOMMENDATIONS

The Maastricht IV/Florence Consensus Report (a periodically updated European study group evaluating Helicobacter management) includes expert opinion-based guidelines for H pylori treatment that recommend using antibiotic susceptibility to select treatment regimens in the event of 2 treatment failures.⁵ The report also notes that bismuth-based quadruple therapy may not be available in all countries and has a more complex dosing regimen, and that local resistance to levofloxacin must be taken into account when prescribing levofloxacin-based triple therapy.
