While probiotics are often used to treat acute gastroenteritis (also known as infectious diarrhea) in children, the latest evidence shows no significant differences in outcomes, compared to a placebo. These results come from the large, double-blind, randomized controlled trial conducted at 10 geographically diverse U.S. pediatric emergency departments. Findings were published in the New England Journal of Medicine.
"This study presents the most robust evidence to date that use of probiotics does not improve outcomes of acute gastroenteritis in children, which calls into question current recommendations," says the author. "Recommendations to use probiotics for these patients were based on previous meta-analyses that have suggested probiotics may be beneficial, but the trials that were included had significant limitations. The rigor of our research design and our results warrant reconsideration of common practice."
Acute gastroenteritis, which can present with diarrhea, vomiting and abdominal pain, accounts for approximately 1.7 million visits to the emergency department and more than 70,000 hospitalizations per year in the U.S. It is the second leading cause of death worldwide in children younger than 5 years.
The study included 943 children, aged 3 months to 4 years of age. Two weeks after an emergency department visit for acute gastroenteritis, children in the study who received a five-day course of probiotic (Lactobacillus rhamnosus) fared no better than the placebo group in terms of illness severity, duration and frequency of diarrhea or vomiting, day-care absenteeism and rate of household transmission of the infection.
