Applying the bronchopulmonary dysplasia framework to necrotizing enterocolitis.

Area of Science:

• Neonatal medicine
• Developmental biology
• Gastroenterology

Background:

• Necrotizing enterocolitis (NEC) is a severe neonatal intestinal disease with high mortality.
• NEC's acute onset and unpredictable nature complicate management.
• The timing of NEC suggests postnatal factors and longitudinal changes are critical.

Purpose of the Study:

• To propose a new conceptual framework for understanding NEC.
• To consider NEC as a disorder of intestinal epithelial development and maladaptation.
• To encourage the incorporation of this developmental perspective into future NEC research.

Main Methods:

• This is a perspective piece, not an experimental study.
• It reviews existing knowledge on NEC pathogenesis and timing.
• It draws parallels with the conceptualization of bronchopulmonary dysplasia.

Main Results:

• NEC is currently viewed as an acute event, but its timing suggests a developmental origin.
• A developmental framework, similar to bronchopulmonary dysplasia, may better explain NEC.
• Longitudinal changes and maladaptation likely precede the necrotic event.

Conclusions:

• Reconsidering NEC as a problem of disordered intestinal development is warranted.
• This perspective shift could enhance understanding of NEC susceptibility and pathogenesis.
• Future research should explore the longitudinal development of NEC.
