Helicobacter Pylori Infection

Brief summary

The aim of this randomized trial is to compare the efficacy and tolerability of H. pylori eradication with a 5-day quadruple therapy versus a clarithromycin-containing triple therapy.

Detailed description

Eligible patients with H pylori infection were randomized to receive either five-day QUAD (esomeprazole 20mg b.d., bismuth subcitrate 120mg q.i.d., tetracycline 250mg q.i.d. and metronidazole 250mg q.i.d.) or EAC (esomeprazole 20mg b.d., amoxicillin 1g b.d. and clarithromycin 500mg b.d.). H. pylori status was rechecked by 13C urea breath test 8 weeks after treatment. Patients who failed their respective therapy were invited to undergo H. pylori susceptibility testing and crossover to receive the alternative regimen for the same duration.

Interventions

First line: 5 days esomeprazole 20mg b.d., bismuth subcitrate 120mg q.i.d., tetracycline 250mg q.i.d. and metronidazole 250mg q.i.d. Cross over second line for those who failed first line: 7 days esomeprazole 20mg b.d., amoxicillin 1g b.d. and clarithromycin 500mg b.d

First line: 7 days esomeprazole 20mg b.d., amoxicillin 1g b.d. and clarithromycin 500mg b.d Second line cross over if failed first line: 7 days quadruple therapy: esomeprazole 20mg b.d., bismuth subcitrate 120mg q.i.d., tetracycline 250mg q.i.d. and metronidazole 250mg q.i.d.)
