Use of Probiotics in the Management of Acute Watery Diarrhoea in Nigerian Children: How Effective are S. Boulardii only Preparations?

Background: Diarrhoeal diseases are a major cause of death worldwide particularly among under-fives and probiotics is used in the management of diarrheal diseases. While some probiotics are of unproven usefulness, others are. Despite the burden of diarrhoea diseases in Africa, there is paucity of studies to support the efficacy or otherwise of S. boulardii among children with diarrheal disease. This study examined the impact of S. boulardii on the clinical course of acute watery diarrhea in children in a tertiary hospital in Nigeria.

Methodology: Two hundred and fifty under-five children with acute watery diarrhoea were recruited and treated in the hospital. One hundred and twenty-five were given probiotics (S. boulardii) in addition to Oral Rehydration solution (ORS), zincand antibiotics while the other one hundred and twenty-five were noton probiotics (Controls). Their stool frequency on the 3rd and 5th day and the duration of the diarrhea, were used to assess outcome. Information was obtained using a questionnaire and then analysed.

Result: Majority of the children (58.8%) were at their second half of infancy (7-12 months). The average number of diarrheal episodes was significantly lower among the subjects by the 3rd day of intervention (t = 2.496, p = 0.013) but not by the 5th day (t = 0.212; p = 0.832). Duration of diarrhea, however, was not significantly different between the subjects and controls (p = 0.246).

Conclusion: S. Boulardiionly probiotic preparations reduce the number of diarrhoeal episodes but not the duration of diarrhea among under- 5s.
