Effects of probiotic and prebiotic on gastrointestinal motility in newborns

To fortify the biological role of milk formula has been suggested to use probiotics and prebiotics as functional components to mimic the effect of breast milk. The aim of this study was to evaluate the effects of prebiotic, probiotic added to a standard formula on gastrointestinal motility respect to placebo-formula. Cutaneous electrogastrography (EGG) and ultrasound gastric emptying (GE) were performed in 49 preterm newborns. 17 newborns were exclusively breast-fed; 32 were randomly assigned to receive prebiotic-added formula (0.8 g/dl of a mixture from scGOS and lcFOS, ratio 9:1) (10), a probiotic-added formula (L. reuteri at dose of 1x10⁸ colony forming units (CFU) per day) (10), a formula with placebo (12) for 30 days. No difference was seen in the nutritional parameters and no adverse events were reported. After the intervention period, the prebiotic, probiotic, and breast milk groups showed a higher percentage of EGG slow wave propagation and faster gastric half emptying time respect to placebo group (ANOVAon ranks p
