HCR.20.064 – MICROSTART: establishing a healthy gut microbiome in preterm newborns in the western world
Research question: What is the relation between the gut microbiome and early life health and disease status in preterm infants, and which factors contribute to positive health outcomes in proof of concept nutritional and microbiota-based interventions? The newborn gut microbiome plays a critical role in healthy development. The interplay between nutrition, gut microbiota, and large numbers of metabolic and immune mediators is at the basis of both normal and perturbed immune-function in the neonatal period. In particular, preterm infants have an immature gut and their standard extended exposure to antibiotics deepens intestinal dysbiosis, limiting the efficacy of nutritional interventions to prevent sepsis, necrotizing enterocolitis and intestinal failure, and to reduce risks of chronic inflammatory and auto-immune diseases, including asthma, obesity, allergy, and impaired neuromotor outcome. A major barrier to elucidating the critical nutrition-host-microbiome interactions and reducing neonatal mortality is the paucity of multi-stacked metagenomics and metabolomics insight. We propose a multidisciplinary consortium, MICROSTART, to explore the correlation between the gut microbiome, early life health and disease status in preterm infants, to determine which factors contribute to positive health outcomes and to test proof of concept interventions with targeted pre/probiotics, initially in animal models and organoids. A large-scale (> 20.000) clinical cohort of pre-term and neonatal samples (infant feces and maternal milk) will be used, combined with state-of-the-art analytical and bioinformatic tools, to determine microbial and metabolic mediators of intestinal health status in infants and neuromotor outcome in infancy. This project builds on a unique longitudinal collection of fecal material from >2000 (still recruiting) preterm and term neonates from 9 Neonatal Intensive Care Units throughout the Netherlands and on maternal milk and feces collected from 120 mother-infant dyads.
