Abstract: Lactobacillus reuteri DSM17938 has shown promise in managing colic, but conflicting study results have prevented a consensus on whether it is truly effective. Through an in idual participant data meta-analysis, we sought to definitively determine if L reuteri DSM17938 effectively reduces crying and/or fussing time in infants with colic and whether effects vary by feeding type. We searched online databases (PubMed, Medline, Embase, the Cumulative Index to Nursing and Allied Health Literature, the Database of Abstracts of Reviews of Effects, and Cochrane), e-abstracts, and clinical trial registries. These were double-blind randomized controlled trials (published by June 2017) of L reuteri DSM17398 versus a placebo, delivered orally to infants with colic, with outcomes of infant crying and/or fussing duration and treatment success at 21 days. We collected in idual participant raw data from included studies modeled simultaneously in multilevel generalized linear mixed-effects regression models. Four double-blind trials involving 345 infants with colic (174 probiotic and 171 placebo) were included. The probiotic group averaged less crying and/or fussing time than the placebo group at all time points (day 21 adjusted mean difference in change from baseline [minutes] −25.4 [95% confidence interval (CI): −47.3 to −3.5]). The probiotic group was almost twice as likely as the placebo group to experience treatment success at all time points (day 21 adjusted incidence ratio 1.7 [95% CI: 1.4 to 2.2]). Intervention effects were dramatic in breastfed infants (number needed to treat for day 21 success 2.6 [95% CI: 2.0 to 3.6]) but were insignificant in formula-fed infants. There were insufficient data to make conclusions for formula-fed infants with colic. L reuteri DSM17938 is effective and can be recommended for breastfed infants with colic. Its role in formula-fed infants with colic needs further research.

Abstract: The aim of this study was to measure consumption and absorption of human milk oligosaccharides (HMOs) in a cohort of premature infants treated with probiotic Bifidobacterium breve. Twenty-nine premature infants (median gestational age 28 weeks, range 23–32 weeks) cared for in the neonatal intensive care unit of the King Edward and Princess Margaret Hospital in Perth, Australia, were treated with B breve at a dose of 1.66 billion organisms per day. S les of feces, urine, and milk were obtained at initiation of the probiotic and again 3 weeks later. 16S ribosomal RNA from the feces was analyzed by next-generation sequencing. Quantitation of HMO content of the milk, urine, and feces was performed using nano-high-performance liquid chromatography-chip/time-of-flight mass spectrometry. There was heterogeneity in colonization with bifidobacteria. “Responders” received milk with higher percentages of fucosylated HMOs and had higher percentages of bifidobacteria and lower percentages of Enterobacteriaceae in their feces than “nonresponders.” Several in idual HMOs in the milk were associated with changes in fecal bifidobacteria over time. Changes over time in milk, fecal, and urine HMOs suggested heterogeneity among HMO structures in consumption by microbes in the gut lumen and absorption from the intestine. Colonization of the premature infant intestinal tract with probiotic B breve is influenced by prebiotic HMOs. B breve is a selective consumer of HMOs in the premature infant.
