This podcast covers emerging topics and challenges in the science of probiotics, prebiotics, synbiotics, postbiotics and fermented foods. This is the podcast of The International Scientific Association for Probiotics and Prebiotic (ISAPP), a nonprofit scientific organization dedicated to advancing the science of these fields.
In this episode, the ISAPP podcast hosts talk about probiotics for preterm infants with Geoff Preidis, MD, PhD, a pediatric gastroenterologist and researcher at Baylor College of Medicine & Texas Children’s Hospital. Predis describes the evidence on probiotics for prevention of necrotizing enterocolitis, the challenges in interpreting the evidence that exists, and using the evidence to make clinical decisions.

This 2020 Cochrane Library review of probiotics for preventing NEC, mortality, and invasive infection (i.e. sepsis), found that “Combined analyses showed that giving very preterm and very low birth weight infants probiotics may reduce the risk of necrotizing enterocolitis, and probably reduces the risk of death and serious infection,” but also noted important concerns about the quality of the trials used to support these conclusions, that, “further, large, high-quality trials are needed to provide evidence of sufficient quality and applicability to inform policy and practice.”

About Dr. Geoff Preidis:
Dr. Preidis received his undergraduate degree in Physics from Harvard University, then completed his medical degree, residency in Pediatrics, fellowship in Pediatric Gastroenterology, Hepatology & Nutrition, and Ph.D. in Translational Biology and Molecular Medicine from Baylor College of Medicine. Now an Assistant Professor at Baylor College of Medicine and Texas Children’s Hospital, Dr. Preidis leads the Nutritional Physiology Research Laboratory and serves as an attending physician on both the Neonatal Gastroenterology, Hepatology & Nutrition Consultation Service and the Transplant Hepatology Service.
Dr. Preidis’s laboratory seeks to define mechanisms through which early life malnutrition impairs intestinal and liver function, leading to both short-term and long-term medical problems. Current studies focus on how malnutrition slows gastrointestinal motility, alters the gut microbiome, and inhibits the liver’s ability to synthesize important substances including bile acids – all of which adversely impact child growth. This research aims to help children suffering from nutritional deficiencies caused by a wide range of medical and socioeconomic factors, including premature newborns in the neonatal intensive care unit.
