Probiotic moderates diarrheal and RTI episodes
Used as a prophylactic, Lactobacillus reuteri DSM 17938 significantly reduced the risk of developing diarrhea or a respiratory tract infection (RTI) in healthy, 6-month-old to 36-month-old children who attended daycare, a study conducted in Mexico showed.
Used as a prophylactic, Lactobacillus reuteri DSM 17938 significantly reduced the risk of developing diarrhea or a respiratory tract infection (RTI) in healthy, 6-month-old to 36-month-old children who attended daycare, a study conducted in Mexico showed.
Investigators recruited subjects for the 6-month-long randomized trial-3 months of intervention and 3 months of follow-up-from 4 different daycare centers. Children in the intervention group received L reuteri in a single daily dose of 1x108 colony-forming units at their first feeding each day, using a dropper bottle containing an oil formulation of the probiotic. The control group was given a placebo.
During the intervention period, L reuteri supplementation reduced the number of days with diarrhea from 0.96 to 0.32 and from 1.1 to 0.5 during the follow-up. The probiotic also significantly reduced the number of diarrheal episodes and their duration during both the intervention and follow-up periods, with a total of 99 and 152 episodes reported in the probiotic and placebo groups, respectively, during the combined 6-month period. The average duration of diarrhea episodes was 1.6 days in the intervention group compared with 2.7 days in the placebo group.
Similarly, L reuteri supplementation reduced the number of days with an RTI from 4.6 to 1.5 during the intervention period and from 4.4 to 2.1 during follow-up. The probiotic also significantly reduced the number of episodes and duration of such infections in both periods. Compared with the placebo group, those receiving L reuteri also had far fewer school absences, medical visits, and days of antibiotic use (Gutierrez-Castrellon P, et al. Pediatrics. 2014;133[4]:e904-e908).
