Insights
Saccharomyces boulardii (S. boulardii) significantly reduced diarrhea duration in young children. Early administration of this probiotic with oral rehydration solution (ORS) accelerated recovery and lowered the risk of prolonged illness.
Area of Science:
- Gastroenterology
- Microbiology
- Pediatrics
Background:
- Acute infectious gastroenteritis is a common cause of illness in young children.
- Oral rehydration solution (ORS) is the standard treatment for dehydration.
- Adjuvant therapies are sought to shorten illness duration and improve outcomes.
Purpose of the Study:
- To assess the efficacy of Saccharomyces boulardii (S. boulardii) as an adjunct to ORS.
- To determine if S. boulardii shortens the duration of acute infectious gastroenteritis in children under 2 years old.
- To evaluate S. boulardii's effect on recovery speed and prolonged diarrhea risk.
Main Methods:
- A double-blind, randomized, placebo-controlled trial was conducted.
- 100 outpatients aged 3-24 months with mild to moderate acute diarrhea were enrolled.
- Participants received either S. boulardii or a placebo for 6 days, alongside ORS.
Main Results:
- The mean diarrhea duration was significantly shorter in the S. boulardii group (4.70 days) compared to placebo (6.16 days).
- S. boulardii treatment led to fewer stools per day on the 4th day of illness.
- The risk of diarrhea lasting over 7 days was substantially reduced with S. boulardii.
Conclusions:
- Saccharomyces boulardii, when used with ORS, effectively decreases diarrhea duration in young children.
- Early administration of S. boulardii (within 48 hours) appears to enhance its efficacy.
- S. boulardii is a promising adjuvant therapy for managing acute gastroenteritis in pediatric ambulatory care.
Objective:
To evaluate the efficacy of the probiotic yeast Saccharomyces boulardii (S. boulardii) as an adjuvant to oral rehydration solution (ORS) in shortening the duration of acute infectious gastroenteritis in children less than 2 years old in ambulatory care.
Materials And Methods:
In a period of 1 year, 100 outpatients between 3 and 24 months old presenting with acute mild to moderate diarrhoea of less than 7 days duration, were included in a double-blind, randomized, placebo-controlled trial evaluating the efficacy of S. boulardii administered for 6 days. Twelve children were lost in follow-up; the data of 88 children could be analysed (44 in the placebo and 44 in the S. boulardii group). Seventy-two patients were followed for one month (37 in the placebo and 35 in the S. boulardii group) allowing the calculation of the duration of diarrhoea.
Results:
The mean duration of diarrhoea was 6.16 days (range 2-13 days) in the placebo group and 4.70 days (range 2-10 days) in the S. boulardii group (p<0.05). On the 4th day, the patients in the S. boulardii group passed 2.5+/-1.4 stools/day versus 3.5+/-1.8 in the placebo group (p<0.001). The risk of having diarrhoea lasting more than 7 days was lower in the S. boulardii group (3/44 versus 12/44; RR 0.25; 95% CI 0.1-0.8). In no patient diarrhoea persisted longer than 14 days. A statistically significant difference was observed in the number of stools on the 4th and 7th day favouring the subgroup that received early treatment (within the first 48 h of the onset of diarrhoea). The administration of antibiotics before inclusion did not make any difference.
Conclusion:
S. boulardii as an adjuvant to ORS in ambulatory care in children less than 2 years old with mild or moderate acute diarrhoea decreased the duration of diarrhoea, accelerated recovery and reduced the risk of prolonged diarrhoea. The data also indicate increased efficacy if S. boulardii is administered within the first 48 h of the onset of diarrhoea.
