Probiotics showed no significant differences in outcome in children with acute gastroenteritis (infectious diarrhea) compared to a placebo. The findings are 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 author Elizabeth Powell, MD, MPH, pediatric emergency medicine specialist at Lurie Children's and Professor of Pediatrics at Northwestern University Feinberg School of Medicine. "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 accounts for about 70,000 hospitalizations per year in the US, presented with the symptoms such as diarrhea, vomiting and abdominal pain.
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.
