Physiological effects of prebiotics and its role in prevention of necrotizing enterocolitis in preterm neonates

Abstract

Necrotizing enterocolitis (NEC) is one of the most serious gastrointestinal emergencies in very low birth weight (VLBW) preterm neonates, affecting 7–14% of these neonates. Due to the seriousness of the disease, prevention of NEC is the most important goal. Current evidence from systematic review and meta-analysis revealed that probiotics are the most promising intervention in reduction of the incidence of NEC in VLBW neonates. As per the evidence, prebiotics modulate the composition of human intestine microflora to the benefit of the host by suppression of colonization of harmful microorganism and/or the stimulation of bifidobacterial growth, decreased stool viscosity, reduced gastrointestinal transit time, and better feed tolerance. Prebiotics may be potential alternatives or adjunctive therapies to probiotics, despite a lack of evidence supporting its clinical efficacy in prevention of NEC. In this article, we discuss evidence-based physiological effects of prebiotics and its therapeutic role in prevention of NEC.
