Lactobacillus reuteri DSM 17938 for the management of infantile colic in breastfed infants: a randomized, double-blind, placebo-controlled trial.
OBJECTIVE To determine whether administration of Lactobacillus reuteri ( L reuteri ) DSM 17938 is beneficial in breastfed infants with infantile colic . STUDY DESIGN Eighty infants aged < 5 months with infantile colic ( defined as crying episodes lasting 3 or more hours per day and occurring at least 3 days per week within 7 days prior to enrollment ) , who were exclusively or predominantly ( > 50 % ) breastfed were r and omly assigned to receive L reuteri DSM 17938 ( 10(8 ) colony-forming units ) ( n = 40 ) or an identically appearing and tasting placebo ( n = 40 ) , both orally , in 5 drops , 1 time daily , for 21 days . The primary outcome measures were the treatment success , defined as the percentage of children achieving a reduction in the daily average crying time ≥ 50 % , and the duration of crying ( minutes per day ) at 7 , 14 , 21 , and 28 days after r and omization . RESULTS The rate of responders to treatment was significantly higher in the probiotic group compared with the placebo group at day 7 ( P = .026 ) , at day 14 ( relative risk ( RR ) 4.3 , 95 % CI 2.3 - 8.7 ) , at day 21 ( RR 2.7 , 95 % CI 1.85 - 4.1 ) , and at day 28 ( RR 2.5 , 95 % CI 1.8 - 3.75 ) . In addition , throughout the study period , the median crying time was significantly reduced in the probiotic group compared with the control group . CONCLUSION Exclusively or predominantly breastfed infants with infantile colic benefit from the administration of L reuteri DSM 17938 compared with placebo
