Summary

This trial is testing whether a postbiotic supplement called Lactobacillus LB (Lactéol®) is safe for hospitalized children under 18 with weakened immune systems who have diarrhea. Participants receive the supplement twice daily for 14 to 28 days alongside standard rehydration and nutrition. The main goal is to monitor for side effects like vomiting, bloating, or allergic reactions, while also exploring whether it helps stop diarrhea and improve stool consistency.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Lactobacillus LB (Lactéol®), a postbiotic dietary supplement
What this could lead to
If safe, it could offer a gentle, supportive option to help manage diarrhea in vulnerable children with weakened immune systems.
What could go wrong
This is an early-phase, small trial focused on safety, not effectiveness. Risks include allergic reactions, worsening diarrhea, or infections, and results may not apply broadly.
