Effect of a Probiotic Infant Formula on Infections in Child Care Centers: Comparison of Two Probiotic Agents
Objective . To investigate the effect of 2 different species of probiotics in preventing infections in infants attending child care centers . Methods . A double-blind , placebo-controlled , r and omized trial was conducted from December 1 , 2000 , to September 30 , 2002 , at 14 child care centers in the Beer-Sheva area of Israel in healthy term infants 4 to 10 months old . Infants were assigned r and omly to formula supplemented with Bifidobacterium lactis ( BB-12 ) , Lactobacillus reuteri ( American Type Culture Collection 55730 ) , or no probiotics . Duration of feeding , including follow-up , for each participant was 12 weeks . All infants were fed only the assigned formula and were not breastfed due to parental decision before recruitment to the study . Probiotic or prebiotic food products or supplements were not allowed . Main outcome measures were number of days and number of episodes with fever ( > 38 ° C ) and number of days and number of episodes with diarrhea or respiratory illness . Results . Participants ( n = 201 ) were similar regarding gestational age , birth weight , gender , and previous breastfeeding . The controls ( n = 60 ) , compared with those fed B lactis ( n = 73 ) or L reuteri ( n = 68 ) , had significantly more febrile episodes ( mean [ 95 % confidence interval ] : 0.41 [ 0.28–0.54 ] vs 0.27 [ 0.17–0.37 ] vs 0.11 [ 0.04–0.18 ] , respectively ) . The controls also had more diarrhea episodes ( 0.31 [ 0.22–0.40 ] vs 0.13 [ 0.05–0.21 ] vs 0.02 [ 0.01–0.05 ] , respectively ) and episodes of longer duration ( 0.59 [ 0.34–0.84 ] vs 0.37 [ 0.08–0.66 ] vs 0.15 [ 0.12–0.18 ] days , respectively ) . The L reuteri group , compared with BB-12 or controls , had a significant decrease of number of days with fever , clinic visits , child care absences , and antibiotic prescriptions . Rate and duration of respiratory illnesses did not differ significantly between groups . Conclusions . Child care infants fed a formula supplemented with L reuteri or B lactis had fewer and shorter episodes of diarrhea , with no effect on respiratory illnesses . These effects were more prominent with L reuteri , which was also the only supplement to improve additional morbidity parameters
