Gut-Brain Axis in Preterm Infants with Surgical Necrotizing Enterocolitis

Area of Science:

• Neonatal Medicine
• Pediatric Neurology
• Gastroenterology

Background:

• Necrotizing enterocolitis (NEC) is a severe gastrointestinal condition affecting 5-10% of very low-birth-weight infants.
• NEC is a primary cause of mortality and long-term morbidity in preterm neonates.
• Preterm infants with NEC, especially surgical cases, exhibit elevated inflammatory markers, significant white matter brain abnormalities, and poor neurodevelopmental outcomes.

Purpose of the Study:

• To review current evidence on clinical factors associated with brain injury in preterm infants with NEC requiring surgical intervention.
• To highlight the need for neuroprotective strategies in this vulnerable population.

Main Methods:

• This review synthesizes existing research and clinical data.
• Focuses on studies evaluating brain injury and neurodevelopmental outcomes in surgical NEC cases.

Main Results:

• NEC is associated with injuries to white matter, grey matter, and cerebellum in neonates.
• Clinical and histopathological factors correlate with gut-associated brain injury in NEC.
• Infants with surgical NEC face significant risks of brain damage.

Conclusions:

• Brain injury is a critical concern in preterm infants with surgical NEC.
• There is an urgent need for effective neuroprotective strategies and interventions to mitigate brain injury and improve long-term neurodevelopmental outcomes in high-risk preterm infants with NEC.
