Abstract Title:
The therapeutic efficacy of Bifidobacterium animalis subsp. lactis BB-12in infant colic: A randomised, double blind, placebo-controlled trial.
Abstract:
BACKGROUND: The pathogenesis of infant colic is poorly defined. Gut microbiota seems to be involved, supporting the potential therapeutic role of probiotics.AIMS: To assess the rate of infants with a reduction of≥50% of mean daily crying duration after 28 days of intervention with the probiotic Bifidobacterium animalis subsp. lactis BB-12(BB-12). Secondary outcomes were daily number of crying episodes, sleeping time, number of bowel movements and stool consistency.METHODS: Randomized controlled trial (RCT) on otherwise healthy exclusively breastfed infants with infant colic randomly allocated to receive BB-12 (1 × 10 CFU/day) or placebo for 28 days. Gut microbiota structure and butyrate, beta-defensin-2 (HBD-2), cathelicidin (LL-37), secretory IgA (sIgA) and faecal calprotectin levels were assessed.RESULTS: Eighty infants were randomised, 40/group. The rate of infants with reduction of≥50% of mean daily crying duration was higher in infants treated with BB-12, starting from the end of 2nd week. No infant relapsed when treatment was stopped. The mean number of crying episodes decreased in both groups, but with a higher effect in BB-12 group (-4.7 ± 3.4 vs -2.3 ± 2.2, P
