"Necrotizing enterocolitis": a paradigm shift

Area of Science:

• Neonatal Medicine
• Gastroenterology
• Biomarker Discovery

Background:

• Necrotizing enterocolitis (NEC) presents with significant heterogeneity in clinical manifestations and underlying pathophysiology.
• Current diagnostic methods, including radiographic criteria and Bell staging, are insufficient to differentiate distinct forms of intestinal injury.
• This lack of precision complicates management strategies and confounds clinical research efforts.

Purpose of the Study:

• To advocate for a paradigm shift away from the singular "NEC" classification.
• To propose a novel, data-driven taxonomy for NEC that integrates clinical trajectories with multiomic analyses.
• To enhance diagnostic accuracy, enable personalized interventions, and improve the design of clinical trials for NEC.

Main Methods:

• Review of existing literature on NEC diagnosis and heterogeneity.
• Conceptual framework for a cluster-based, data-driven classification system.
• Integration of clinical data with multiomic (e.g., genomic, transcriptomic, proteomic) datasets.

Main Results:

• Current diagnostic approaches fail to capture the biological diversity within NEC.
• A proposed taxonomy would allow for mechanism-informed diagnoses.
• Personalized treatment strategies and more effective clinical trials are anticipated outcomes.

Conclusions:

• Abandoning the monolithic "NEC" label is crucial for advancing patient care.
• A data-driven, mechanism-based classification system promises more precise diagnoses and targeted therapies.
• This approach will ultimately improve outcomes for vulnerable neonatal patients suffering from intestinal injury.
