Impact of Emergency Department Probiotic (LGG) Treatment of Pediatric Gastroenteritis
"Can probiotics help children with stomach flu?"
3 months to 4 years old
Healthy Volunteers:
Stomach flu, gastroenteritis
Drug study, Phase 2/3
The purpose of this research study is to improve the care of children who are suffering from intestinal infections by using a probiotic. Probiotics are bacteria present in nutritional supplements and foods such as yogurt that are believed to be safe and good for people. Early research suggests that probiotics may help children with intestinal infections. In this study we will look at the use of a probiotic called LGG compared to a placebo (sometimes referred to as a “sugar pill”) in children with intestinal infections. This study will help us know whether probiotics may help these children.
LGG is considered investigational, which means that it has not been approved by the U.S. Food and Drug Administration to be used as a medication. However the FDA has given us permission to use LGG as part of this study
This study requires

History and physical form completed by child's pediatrician Stool sample Probiotic/Placebo administration Surveys completed on-line or phone call Complete diary provided
