NCT07260006

Brief Summary

The goal of this clinical trial is to learn if including bismuth in the treatment helps heal stomach and duodenal ulcers caused by Helicobacter pylori (H. pylori) in children. The main questions it aims to answer are:

  • Does a treatment plan with bismuth work better than a plan without bismuth to clear the infection?
  • Is the bismuth plan more cost-effective while still safe and effective? Researchers will compare two treatment groups to see which works better. Participants will:
  • Take one of the two assigned treatment plans (with or without bismuth) for the standard treatment duration
  • Visit the clinic for checkups and tests to confirm infection clearance and monitor side effects
  • Keep a diary of symptoms, medication use, and any side effects

Outcome Measures

Primary Outcomes (1)

  • Eradication rate of Helicobacter pylori infection between the two treatment regimens

    The efficacy of the two regimens will be evaluated by comparing H. pylori eradication rates. Clinical examination and a urea breath test or stool antigen test will be performed after completion of therapy to confirm eradication. Patients will receive a 14-day treatment regimen, followed by an additional 2-4 weeks of proton pump inhibitor (PPI) therapy to promote healing of gastric or duodenal lesions.

    Two weeks after discontinuation of acid suppression therapy following completion of the eradication regimen.

Study Arms (2)

Bismuth quadruple therapy

EXPERIMENTAL

Patients in this arm will receive PPI, Amoxicillin, Metronidazole, and Bismuth for 14 days, with doses adjusted according to weight and age.

Drug: Bismuth quadruple therapy

Triple therapy with PPI + Amoxicillin + Metronidazole

EXPERIMENTAL

Patients in this arm will receive PPI, Amoxicillin, Metronidazole for 14 days, with doses adjusted according to weight and age.

Drug: Triple therapy with PPI + Amoxicillin + Metronidazole

Interventions

A 14-day regimen including proton pump inhibitor (PPI; esomeprazole \[Nexium MUPS\]), bismuth subcitrate (or bismuth subsalicylate), amoxicillin, and metronidazole. All drug doses are adjusted according to the participant's age and weight.
