Comparing Impacts of Donor Human Milk to Formula Supplementation on the Gut Microbiome of Full-term Infants Exposed to Antibiotics in Labour: A Pilot Randomized Controlled Trial

University of Calgary·interventional·Posted Apr 18, 2023·Updated Feb 20, 2026

In Brief

A clinical study evaluating Donor Human Milk - Nutritional Replacement for Microbial Colonization. Completed, enrolled 105 participants across 1 site.

Detailed Summary

The goal of this pilot randomized controlled trial (RCT) is to examine donor human milk (DHM) as a clinical intervention targeted at achieving beneficial microbiome signatures in full-term infants who are exposed to intrapartum antibiotic prophylaxis (IAP) therapy during labour. Secondarily, this study aims to compare the infant health outcomes of sleep and growth between groups to assess if these outcomes are mediated by infant feeding type or potential differences in microbial signatures. Finally, this study will compare maternal outcomes of depression, anger, breastfeeding self-efficacy and breastfeeding rates between groups. The hypothesis of this study is: that replacing formula with DHM supplementation will minimize gut microbiome dysbiosis and foster homeostasis following supplementation. In addition, it is hypothesized that improved homeostasis will promote improved sleep and growth outcomes in participant infants. Finally, mothers whose infants receive DHM will have lower depression and anger scores and high breastfeeding self-efficacy and exclusive breastfeeding rates compared to mothers whose infants receive formula.

Interventions

Donor Human Milk - Nutritional Replacementother

All DHM in North America is pasteurized and provided through certified milk banks regulated by the Human Milk Banking Association of North America. DHM for this study will be obtained from the NorthernStar Mothers Milk Bank (NMMB). The milk is pasteurized and rigorously tested according to Human Milk Banking of North America guidelines. In Canada, DHM is categorized as food or nutritional therapy and the milk bank is monitored and certified by the Canadian Food Inspection Agency. The product used for this study will be the same product that is provided to other hospital units (mainly the neonatal intensive care units) in Alberta and around Canada. The product will not be modified or tampered with in any way.
