Early Persistent Blood Eosinophilia in Necrotizing Enterocolitis Is a Predictor of Late Complications.

Background: Eosinophils infiltrate intestinal tissue during necrotizing enterocolitis (NEC) and adult bowel diseases. We theorized that epithelial damage causes eosinophilic activation and recruitment at NEC onset.

Objective: We studied the relationship between persistent blood eosinophilia and medical or surgical complications during NEC.
