Lactobacillus reuteri DSM 17938 in Infantile Colic: A Randomized, Double-Blind, Placebo-Controlled Trial
OBJECTIVE : To test the efficacy of Lactobacillus reuteri on infantile colic and to evaluate its relationship to the gut microbiota . STUDY DESIGN : Fifty exclusively breastfed colicky infants , diagnosed according to modified Wessel 's criteria , were r and omly assigned to receive either L reuteri DSM 17 938 ( 108 colony-forming units ) or placebo daily for 21 days . Parental question naires monitored daily crying time and adverse effects . Stool sample s were collected for microbiologic analysis . RESULTS : Forty-six infants ( L reuteri group : 25 ; placebo group : 21 ) completed the trial . Daily crying times in minutes/day ( median [ interquartile range ] ) were 370 ( 120 ) vs 300 ( 150 ) ( P = .127 ) on day 0 and 35.0 ( 85 ) vs 90.0 ( 148 ) ( P = .022 ) on day 21 , in the L reuteri and placebo groups , respectively . Responders ( 50 % reduction in crying time from baseline ) were significantly higher in the L reuteri group versus placebo group on days 7 ( 20 vs 8 ; P = .006 ) , 14 ( 24 vs 13 ; P = .007 ) , and 21 ( 24 vs 15 ; P = .036 ) . During the study , there was a significant increase in fecal lactobacilli ( P = .002 ) and a reduction in fecal Escherichia coli and ammonia in the L reuteri group only ( P = .001 ) . There were no differences in weight gain , stooling frequency , or incidence of constipation or regurgitation between groups , and no adverse events related to the supplementation were observed . CONCLUSION : L. reuteri DSM 17 938 at a dose of 108 colony-forming units per day in early breastfed infants improved symptoms of infantile colic and was well tolerated and safe . Gut microbiota changes induced by the probiotic could be involved in the observed clinical improvement
