Comparison of epidermal growth factor and heparin-binding epidermal growth factor-like growth factor for prevention of experimental necrotizing enterocolitis.

Background: Necrotizing enterocolitis (NEC) is a devastating gastrointestinal disease of prematurely born infants. Epidermal growth factor (EGF) and heparin-binding EGF-like growth factor (HB-EGF) have protective effects against intestinal injury. The aim of this study was to compare the effect of oral administration of HB-EGF, EGF, or both on the incidence of NEC in a neonatal rat model.

Decreased development of necrotizing enterocolitis in IL-18-deficient mice.

Necrotizing enterocolitis (NEC) is a devastating gastrointestinal disease predominantly of prematurely born infants, characterized in its severest from by extensive hemorrhagic inflammatory necrosis of the distal ileum and proximal colon. Proinflammatory cytokines have been implicated in the development of NEC, and we have previously shown that IL-18 is significantly elevated in the well-established neonatal rat model of NEC. To determine whether IL-18 contributes to intestinal pathology in NEC, we subjected IL-18 knockout mice to the protocol used to develop experimental NEC in newborn rats.

Reduction of experimental necrotizing enterocolitis with anti-TNF-alpha.

Necrotizing enterocolitis (NEC) is the most common gastrointestinal disease of premature infants. However, despite significant morbidity and mortality, the etiology and pathogenesis of NEC are poorly understood. Evidence suggests that ileal proinflammatory mediators such as IL-18 contribute to the pathology associated with this disease.
