NCT ID NCT07342101
First seen Jun 27, 2026 · Last updated Sep 11, 2026 · Updated 1 time
Summary
This study tests whether adding a probiotic called Lacticaseibacillus rhamnosus GG to standard care (like rehydration fluids) can shorten the duration of acute infectious diarrhea in children. About 480 kids aged 1 month to 10 years in Turkey will take part. Half will get the probiotic plus standard care, and half will get standard care alone. Families will track stool frequency and consistency for 10 days.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Lacticaseibacillus rhamnosus GG (a probiotic, 5 billion CFU twice daily for 6 days)
- What this could lead to
- If it works, this could provide a simple, safe way to shorten diarrhea in children and reduce hospital stays.
- What could go wrong
- This is an early-stage trial with no phase, and results may not apply to all children. The probiotic may not work better than standard care alone.
