Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study evaluates the effects of either Pediasure or Nourish formulas on the gastrointestinal microbiome in critically-ill children. Patients will be randomized to received either Pediasure or Nourish.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The gastrointestinal microbiome has been shown to be altered in critically-ill children such that there is a larger shift toward pathogenic bacteria. Previous studies have shown that probiotics, fecal transplants, antibiotic decontamination, and dietary interventions can shift the gastrointestinal microbiome toward a metabolically favorable microbiome profile and be associated with improvements in disease burden.

This study will randomize critically-ill children who are stable enough for enteral tube feedings to receive either Pediasure or Nourish. Pediasure is a commercially-made formula that is used commonly in pediatric patients. Nourish is an organic, whole-food formula with a high fiber content. High-fiber diets have been correlated with metabolically favorable microbiome profiles. This study will look at the microbiome before and after initiation of enteral tube feedings to determine if either formula is associated with a shift in the microbiome toward a favorable profile.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Critically-ill children who are medically stable and ready for enteral tube feeds will be randomized to receive either Pediasure or Nourish. Nutritional needs will be calculated per previously established standards at our institution and performed in conjunction with trained dieticians and nutritionists.
