Long-Term Safety and Impact on Infection Rates of Postnatal Probiotic and Prebiotic (Synbiotic) Treatment: Randomized, Double-Blind, Placebo-Controlled Trial
OBJECTIVE . Live probiotic bacteria and dietary prebiotic oligosaccharides ( together termed synbiotics ) increasingly are being used in infancy , but evidence of long-term safety is lacking . In a r and omized , placebo-controlled , double-blind trial , we studied the safety and long-term effects of feeding synbiotics to newborn infants . METHODS . Between November 2000 and March 2003 , pregnant mothers carrying infants at high risk for allergy were r and omly assigned to receive a mixture of 4 probiotic species ( Lactobacillus rhamnosus GG and LC705 , Bifidobacterium breve Bb99 , and Propionibacterium freudenreichii ssp shermanii ) or a placebo for 4 weeks before delivery . Their infants received the same probiotics with 0.8 g of galactooligosaccharides , or a placebo , daily for 6 months after birth . Safety data were obtained from clinical examinations and interviews at follow-up visits at ages 3 , 6 , and 24 months and from question naires at ages 3 , 6 , 12 , and 24 months . Growth data were collected at each time point . RESULTS . Of the 1018 eligible infants , 925 completed the 2-year follow-up assessment . Infants in both groups grew normally . We observed no difference in neonatal morbidity , feeding-related behaviors ( such as infantile colic ) , or serious adverse events between the study groups . During the 6-month intervention , antibiotics were prescribed less often in the synbiotic group than in the placebo group ( 23 % vs 28 % ) . Throughout the follow-up period , respiratory infections occurred less frequently in the synbiotic group ( geometric mean : 3.7 vs 4.2 infections ) . CONCLUSION . Feeding synbiotics to newborn infants was safe and seemed to increase resistance to respiratory infections during the first 2 years of life
