Is this trial a fit for you?

Likely a good fit

Children with endoscopy- or histology-confirmed gastritis or peptic ulcer and confirmed H. pylori infection whose parent or legal guardian provides consent and who meet medication-use windows are ideal candidates.

Probably not a fit

Children who are allergic to any study medications, who have used antibiotics or bismuth recently, or who cannot complete scheduled follow-up visits are unlikely to receive benefit from participation.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study compares a bismuth quadruple regimen with a standard triple therapy (PPI + amoxicillin + metronidazole) in children who have endoscopy- or histology-confirmed peptic ulcers and H. pylori infection. Participants receive one of the two assigned regimens for the standard treatment duration and return for clinic visits and tests to confirm infection clearance and ulcer healing. Parents or guardians keep a diary of symptoms, medication use, and side effects while study staff monitor safety and adherence. The study also includes a cost-effectiveness component to see whether adding bismuth yields better value alongside clinical outcomes.

Why it matters

Potential benefit: If successful, adding bismuth could increase H. pylori eradication rates and speed ulcer healing in children while remaining cost-effective.

How similar studies have gone: Bismuth-containing regimens have improved eradication rates in adults and can help overcome antibiotic resistance, but pediatric evidence is more limited and this approach is less established in children.
