Sequential Therapy Versus Quadruple Therapy in H. Pylori Eradication

Summary

The investigators aimed to 1. compare the eradication rates and long term re-infection rates of sequential therapy for 14 days versus bismuth quadruple therapy for 10 days in the first line and second line treatment 2. assess the impact of antibiotic resistance and CYP2C19 polymorphism on the eradication rate of these regimens 3. assess the impact of these eradication regimens on the antibiotic resistance and microbiota of the gut flora 4. assess the impact of eradication therapy on the metabolic factors

Outcome

Met primary endpoint

paper Optimized 14 day sequential therapy was non-inferior to, but better tolerated than 10 day bismuth quadruple therapy and both may be used in first-line treatment in populations with low to intermediate clarithromycin resistance. PMID 29846605 ↗
