Clinical Trial Summary

Background: Oropharyngeal administration of colostrum (OAC) has an immune stimulating effect on oropharyngeal-associated lymphoid tissue, and can also promote the maturation of the gastrointestinal tract. However, how OAC promotes intestinal maturation in preterm infants by altering the gut microbiota remains unclear. We aim to assess the changes of gut microbiota and metabolites after OAC in very preterm infants. Methods: A multicenter, double-blind, randomized controlled trial will be conducted in 3 large NICUs in Shenzhen, China, for preterm infants with gestational age less than 32 weeks and birth weight less than 1500g. The intervention group will be given 0.2ml colostrum for oropharyngeal administration every 3 hours, which will start between the first 48 to 72 hours and continue for 5 consecutive days; The control group will be given sterile water for oropharyngeal administration, and the administration scheme will be the same as above. Stool samples will be collected at the first defecation and the 7th day after birth. It is estimated that 320 preterm infants will participate in the study within 1 year. 16sRNA gene sequencing and liquid chromatography-mass spectrometry will be used to analyze the effect of OAC on gut microbiota and metabolites. Discussion: The proposal advocates for the promotion of OAC as a safe and relatively beneficial initiative among neonatal intensive care units, and this initiative may contribute to the establishment of a dominant intestinal flora. Findings of this study may help to improve the health outcomes of preterm infants by constructing targeted gut microbiota in future studies.


Clinical Trial Description

Preterm infants with gestational age < 32 weeks and weight < 1500g will be evaluated. Infants who met the inclusion criteria will be randomly divided into two groups according to the ratio of 1:1. The intervention group will be given oropharyngeal colostrum every 3 hours for 5 days; the control group will be given sterile water with the same dosage and administration scheme. Stool samples will be collected at the first defecation and the 7th day to detect the gut microbiota and metabolites. ;
