Is this trial a fit for you?

Likely a good fit

Ideal candidates are children aged 1 month to 14 years who need PPI therapy for gastroesophageal reflux disease or functional dyspepsia.

Probably not a fit

Patients with neurological disorders, known immunodeficiencies, or those who have recently taken other probiotics or prebiotics may not benefit from this study.

What this trial studies

This study investigates the effects of a probiotic combination, Gastrus, containing two strains of Lactobacillus reuteri, on children who are being treated with proton pump inhibitors (PPIs). The primary goals are to determine if Gastrus can reduce the incidence of small intestinal bacterial overgrowth (SIBO), lower the risk of infections, and maintain gut microbiota balance during PPI therapy. Participants will receive either Gastrus or a placebo for eight weeks, with follow-up evaluations conducted after treatment cessation. Compliance will be monitored through alarms to ensure participants take the required doses.

Why it matters

Potential benefit: If successful, this approach could significantly improve gut health and reduce infection risks in children requiring long-term PPI therapy.

How similar studies have gone: Previous studies have shown promising results with probiotics in managing gut health, suggesting potential success for this approach.
