Background
Persistent diarrhoea (diarrhoea lasting more than 14 days) accounts for one third of all diarrhoea related deaths in developing countries in some studies. Probiotics may help treatment.Objectives
To evaluate probiotics for treating persistent diarrhoea in children.Search strategy
In August 2010, we searched the Cochrane Infectious Diseases Group Specialized Register, CENTRAL, MEDLINE, EMBASE, and LILACS. We also contacted authors of included trials and organizations working in the field, and checked reference lists.Selection criteria
Randomized controlled trials comparing a specified probiotic agent with placebo or no probiotic in children with persistent diarrhoea.Data collection and analysis
Two review authors assessed the eligibility, risk of bias, extracted and analysed data. Differences were resolved by discussion. Statistical analysis were performed using the fixed-effect model and the results were expressed as mean difference (MD) for continuous outcomes with 95% confidence intervals (CI).Main results
Four trials were included, with a total number of 464 participants; one trial had a low risk of bias. Meta-analysis showed that probiotics reduced the duration of persistent diarrhoea (mean difference 4.02 days, 95% CI 4.61 to 3.43 days, n=324, 2 trials). Stool frequency was reduced with probiotics in two trials. One trial reported a shorter hospital stay, which was significant, but numbers were small. No adverse events were reported.Authors' conclusions
There is limited evidence suggesting probiotics may be effective in treating persistent diarrhoea in children.Plain language summary
Probiotics for persistent diarrhoea in children
Persistent diarrhoea is defined as a diarrhoeal episode that starts acutely but then lasts for 14 days or more, and it is an important cause of morbidity and mortality in children under five years old in developing countries throughout the world. The cause of persistent diarrhoea is not completely understood but is likely to be complex; this in turn makes management of the condition difficult. Probiotics are bacteria and yeasts that are similar to the normal bacteria found in a healthy gut. These so called friendly bacteria have been used in several studies to treat acute infectious diarrhoea with encouraging results. This review found four trials involving children with persistent diarrhoea. Two studies with a combined total of 324, showed that probiotics shorten the duration of diarrhoea and reduce the stool frequency on day 5. One study (235 children) suggested that probiotics reduce the hospital stay. Three out of four trials reported that no adverse events occurred. However, this review is limited by few trials with small number of participants, and therefore may not represent a reliable estimate of probiotics' effect.
