Influences of High-fiber, Organic Whole-food Formula on the Gut Microbiome in Critically Ill Children

Not applicable Interventional University of Pittsburgh · NCT03414775

This study tests if a high-fiber feeding formula can improve gut health in critically ill children aged 1-17 by changing their gut bacteria for the better.

What this trial studies

This study evaluates how two different enteral feeding formulas, Pediasure and Nourish, affect the gastrointestinal microbiome in critically ill children aged 1-17 years. Participants will be randomized to receive either formula while being monitored for changes in their microbiome profile. The study aims to determine if a high-fiber, organic formula can shift the microbiome towards a more favorable composition, potentially improving health outcomes. The research will analyze microbiome samples before and after the initiation of enteral feeding.

Who should consider this trial

Good fit: Ideal candidates are critically ill children aged 1-17 years who are stable enough for enteral tube feedings.

Not a fit: Patients with specific dietary needs or allergies to the formulas being tested may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved gut health and overall outcomes for critically ill pediatric patients.

How similar studies have performed: Previous studies have shown that dietary interventions can positively influence the microbiome, suggesting potential success for this approach.
