Original title: Synbiotic supplementation leads to gut microbiome communities with functional capacity linked to better brain white matter development in preterm infants
The researchers studied very and extremely preterm infants given a daily supplement containing a bacterium, special sugars, and an amino acid. They tracked gut microbes over time and used MRI near the time a full-term birth would occur to assess brain development. The supplement helped Bifidobacterium become established early and increased the microbes’ capacity to make amino acids and produce acetate and lactate. Those same capacities were lower in infants whose white matter, the brain’s signal-carrying tissue, showed delayed maturation.
Imagine tending a garden while a young plant is still growing. Some soil conditions help useful plants take hold and produce what the garden needs, while other conditions can slow the plant’s growth. In this paper, the supplement is the change to the soil, the gut microbes are the plants, and brain scans show how white matter is developing.
Very and extremely preterm infants face risks to brain development, and their gut microbes may be one changeable part of that picture. The study links a nutritional supplement with microbial functions that were lower in infants whose white matter matured more slowly.
This is a secondary analysis, and the link between microbial functions and delayed white-matter myelination was found through post hoc analysis. The abstract does not establish that the microbial changes caused better brain development or report whether the supplement improved long-term developmental outcomes.
