Probiotics for prevention of necrotizing enterocolitis: Where do we stand?

In this review, we provide a historical perspective on probiotic use in preterm infants. We review recent data on the treatment effects of probiotics on necrotizing enterocolitis, sepsis, and mortality. We highlight guidance statements from professional societies and organizations, discussing key points within the context of the currently available evidence from both randomized trials and cohort studies. Finally, we summarize experiences from several North American centers that have reported on the routine use of probiotics, including our center. Our goal is to highlight some of the considerations and complexities surrounding routine probiotics use in preterm infants.
