MedicalResearch.com: What are the main findings of the study?

Dr. Sung: The systematic review identified 12 studies (1825 infants)  that investigated the use of probiotics to treat or prevent infant colic (excessive crying of unknown cause in babies less than 3 months old). Three of the 5 treatment trials concluded probiotics effectively treat colic in breastfed babies; one suggested possible effectiveness in formula-fed babies with colic, and one suggested ineffectiveness in breastfed babies with colic. The three effective trials used the probiotic Lactobacillus reuteri in breastfed babies only; in two of these trials, the mothers were on a dairy-free diet. Five of the 7 prevention trials suggested probiotics to be ineffective in preventing colic.

MedicalResearch.com: 
Were any of the findings unexpected?

Dr. Sung: 

Recent studies have shown differences in gut flora between babies with colic and those without. Probiotics are known to alter gut flora and their effects are strain-specific. The mixed findings from this review are not surprising, as studies used a wide variety of probiotic strains, and the gut flora of breastfed babies are likely different from those who are formula-fed.

MedicalResearch.com: What should clinicians and patients take away from your report?


Dr. Sung: There is still insufficient evidence to support the routine use of probiotics for infants with colic, especially in formula-fed babies.

MedicalResearch.com: What recommendations do you have for future research as a result of this study?

Dr. Sung: Larger and more rigorously designed randomized clinical trials are needed to examine the efficacy of the probiotic Lactobacillus reuteri in the management of breastfed and particularly formula-fed infants with colic and in the prevention of colic in healthy term infants.
