Oxidative Stress and Necrotizing Enterocolitis: Pathogenetic Mechanisms, Opportunities for Intervention, and Role of Human Milk

الملخص EN

This review will examine the role of oxidative stress (OS) in the pathogenesis of necrotizing enterocolitis (NEC) and explore potential preventive and therapeutic antioxidant strategies.

Preterm infants are particularly exposed to OS as a result of several perinatal stimuli and constitutive defective antioxidant defenses.

For this reason, OS damage represents a contributing factor to several complications of prematurity, including necrotizing enterocolitis (NEC).

Being NEC a multifactorial disease, OS may act as downstream component of the pathogenetic cascade.

To counteract OS in preterm infants with NEC, several antioxidant strategies have been proposed and different antioxidant compounds have been experimented.

It is well known that human milk (HM) is an important source of antioxidants.

At the same time, the role of an exclusive HM diet is well recognized in the prevention of NEC.

However, donor HM (DHM) processing may impair antioxidant properties.

As DHM is becoming a common nutritional intervention for high risk PI, the antioxidant status of preterm and DHM and potential ways to preserve its antioxidant capacity may merit further investigation.
