Introduction
Acute gastroenteritis affects millions of children in the U.S. every year, leading to emergency department visits and hospitalizations. Probiotics, particularly Lactobacillus rhamnosus GG (LGG), have been commonly used as a treatment, but evidence supporting their effectiveness has been limited. A new study conducted by the Pediatric Emergency Care Applied Research Network (PECARN) aimed to determine whether LGG could reduce the severity of gastroenteritis in children. The trial found that LGG did not significantly improve outcomes compared to placebo.
Why is this important for patients and caregivers?
The study clarifies that probiotics, particularly LGG, may not be as beneficial as previously thought for treating acute gastroenteritis in children.This can help caregivers make informed decisions about the use of probiotics during their child’s illness.Reducing unnecessary treatments can also reduce medical costs and the burden of administering non-beneficial interventions. Parents often use probiotics, like Lactobacillus rhamnosus GG, hoping to reduce the severity of their child’s gastroenteritis. However, this large study shows that probiotics do not significantly shorten illness duration, improve symptoms, or reduce the need for additional medical visits. By using the latest research, parents can focus on more effective treatments like hydration. |
Study question
Does administering Lactobacillus rhamnosus GG to children with acute gastroenteritis reduce the incidence of moderate-to-severe disease compared to placebo?
Study design
This randomized, double-blind, placebo-controlled trial included 971 children between the ages of 3 months and 4 years who presented to 10 U.S. emergency departments. The children received either LGG or a placebo for five days, and their symptoms were monitored for two weeks.
Results
The study found no significant difference between the LGG and placebo groups in terms of moderate-to-severe gastroenteritis (11.8% vs. 12.6%, respectively). There were also no differences in the duration of diarrhea or vomiting, day-care absenteeism, or household transmission of symptoms.
Caution
While this study provides important insights, it is worth noting that probiotics may still play a role in other health contexts. However, for pediatric gastroenteritis, the evidence suggests they do not provide significant benefits.
A brief message from the principal investigator
Take Home Points
Lactobacillus rhamnosus GG does not reduce the severity or duration of gastroenteritis symptoms in children.Caregivers should prioritize hydration and symptomatic care over probiotics for managing gastroenteritis.The findings may shift the approach to treating pediatric gastroenteritis in both clinical and home settings. |
