Insights

Gut microbiota development is crucial for infant health. Dysbiosis in preterm infants is linked to acute illnesses and long-term issues, highlighting the need for microbiota interventions.

Area of Science:

  • Microbiology
  • Neonatology
  • Gastroenterology

Background:

  • The gut microbiota develops significantly from birth, influencing lifelong health.
  • Disruptions in gut microbiota development, known as dysbiosis, are common in preterm infants.
  • The gut-organ axis describes how gut microbiota impacts remote organs, with implications for disease.

Purpose of the Study:

  • To review evidence on gut microbiota and morbidities in preterm infants.
  • To explore the role of the gut-organ axis in preterm infant health.
  • To provide insights into future microbiota interventions for preterm infants.

Main Methods:

  • Literature review of existing evidence.
  • Analysis of studies on gut microbiota and preterm infant morbidities.
  • Exploration of gut-organ axis pathways.

Main Results:

  • Gut dysbiosis in preterm infants is associated with acute morbidities like necrotizing enterocolitis, late-onset sepsis, bronchopulmonary dysplasia, and retinopathy of prematurity.
  • Gut dysbiosis may also negatively impact long-term neurodevelopment and somatic growth in preterm infants.
  • The gut-organ axis plays a significant role in mediating these effects.

Conclusions:

  • Gut microbiota plays a critical role in preterm infant health, influencing both acute and long-term outcomes.
  • Understanding the gut-organ axis is key to comprehending the impact of dysbiosis.
  • Targeted microbiota interventions hold promise for improving preterm infant health.
