Role of platelet-activating factor in the pathophysiology of necrotizing enterocolitis

Necrotizing enterocolitis (NEC) is a devastating gastrointestinal illness that affects predominantly preterm infants. Treatment options are limited and NEC remains a significant cause of morbidity and mortality. The precise aetiology of NEC remains unclear but evidence strongly suggests that the cause is multifactorial and there are four main aetiological factors: prematurity, hypoxia. enteral feeding and bacterial colonization. The presence of similar intestinal lesions, regardless of aetiological trigger, strongly implicates a final common pathway in the pathogenesis. There is now a substantial body of evidence to indicate that endogenous inflammatory mediators, particularly platelet-activating factor (PAF), play a vital role in this final pathway, Conclusion: The use of agents that antagonize PAF may provide therapeutic options in the management of NEC.
