Effect of Rectal Administration of Breast Milk on Gut Microbiota in Preterm Infants (premic)

Effect of Rectal Administration of Human Milk on Gut Microbiota and Clinical Outcomes in Preterm Infants: A Randomized Controlled Study

This study aims to evaluate the effect of rectal administration of maternal breast milk on gut microbiota development in preterm infants. Preterm infants are at increased risk of dysbiosis due to immaturity and limited enteral feeding in the early postnatal period. In this randomized controlled study, preterm infants will receive either rectal administration of maternal breast milk or normal saline. The primary objective is to compare gut microbiota composition between the two groups. The findings may provide insight into a novel and non-invasive strategy to support microbiota development in preterm infants.

Gedetailleerde beschrijving

Preterm infants are highly vulnerable to alterations in gut microbiota due to immaturity, delayed enteral feeding, antibiotic exposure, and environmental factors. Early-life dysbiosis has been associated with adverse outcomes including necrotizing enterocolitis, sepsis, and impaired immune development. Strategies to promote healthy microbiota colonization in preterm infants are therefore of significant clinical interest.

Breast milk contains beneficial bacteria, prebiotics, and bioactive components that play a critical role in shaping neonatal gut microbiota. However, in the early postnatal period, especially in very preterm infants, enteral feeding may be limited or delayed. Alternative routes of exposure to breast milk components may offer a potential strategy to influence microbiota development.

This randomized controlled study aims to investigate the effects of rectal administration of maternal breast milk on gut microbiota in preterm infants. Participants will be randomly assigned to receive either rectal maternal breast milk or normal saline. Stool samples will be collected at predefined time points to assess microbiota composition.

The study is designed to explore whether rectal exposure to breast milk can modulate early microbial colonization and provide a feasible, safe, and innovative approach to support gut microbiota development in preterm infants.

Experimenteel: Rectal irrigation with maternal breast milk
Rectal irrigation will be performed starting 48 hours after birth, twice daily for 5 consecutive days at 09:00 and 21:00. A 6 Fr feeding tube, 5 mL syringe, thermostatically controlled water bath (set at 37°C), sterile water-based lubricant, and sterile gloves will be used. The enema volume will be calculated as 5 mL/kg and warmed to 37°C. One end of the feeding tube will be connected to the syringe, and the other end will be gently inserted into the rectum after lubrication. The solution will be administered slowly over approximately 3 minutes, and the tube will then be carefully removed. Maternal breast milk will be used for rectal irrigation.
