BACKGROUND: Probiotic Lactobacillus reuteri and reduced allergen load may lessen the daily crying of colic infants, but the role of Lactobacillus rhamnosus GG (LGG) has remained obscure. METHODS:Infants with colic (n = 30) were enrolled during the first 6 wk of life. All families received behavioral support and allergen avoidance diet: breastfeeding mothers followed cow's milk elimination diet and formula-fed infants received extensively hydrolyzed casein formula. The randomized, double-blind intervention employed of LGG 4.5 × 10(9) cfu/d or placebo for a 4-wk study period. Daily crying was recorded by diaries and parental interviews. Fecal calprotectin and gut microbiota composition by quantitative PCR were evaluated before and after the intervention. RESULTS:Daily crying time was comparable between the probiotic (173 min) and the placebo group (174 min; P = 0.99) at the end of the intervention according to the parental diary. However, parents reported a decrease of 68% (95% confidence interval (CI): 58-78) in daily crying in the probiotic and 49% (95% CI: 32-66) in the placebo group (P = 0.05). CONCLUSION:LGG in infants treated in tandem with behavioral support and a cow's milk elimination diet did not provide additional treatment effect for diary-verified colic crying although parental report of crying suggested the probiotic intervention effective.
