prebiotic in preterm infants

Conditions: Preterm Infant; Development, Infant; Nutrition

Summary: this is a double blinded, randomized, controlled trial of prebiotic in infants born between 26 and 32 weeks gestational age. the investigators anticipate enrollment of 90 subjects in total and for the study to be completed in 18 months. the investigators anticipate collecting clinical data, anthropometrics, stool samples (requiring appropriate storage through analysis), salivary samples from mother and infant, discarded blood samples from baby after the standard care lab tests are done, a single, optional blood draw at the conclusion of the study, and subjecting infants to a neurodevelopmental survey at study completion. the overall goal of this study is to test prebiotic administration to human milk-fed infants who are 700 gram to 1800 gram birthweight. the goal of this study will be addressed through one primary aim, a secondary aim, and exploratory aims, indicated below: primary aim: compare weight, length, and head circumference z-score growth between the study and placebo groups. secondary aim: compare the time taken to achieve full feedings (135 ml/kg/day or more) between the study and placebo groups. exploratory aim 1: compare neurobehavior, as measured by the validated neonatal intensive care unit network neurobehavioral scale (nnns), between the study and placebo groups. exploratory aim 2: compare fecal calprotectin levels to determine the impact of supplementation on reducing intestinal inflammation between the study and placebo groups. exploratory aim 3: compare fecal microbiome between the prebiotic and placebo groups, to determine whether there is a shift in microbial composition towards bifidobacteria and other microbes that are capable of metabolizing prebiotic.
