Probiotics for Diarrhoea

Empirical evidence for the clinical effectiveness of probiotics has shown mixed results and we still know very little about which probiotics work for which indication and group of patients. In order to be of informational value, the effectiveness of probiotics needs to be demonstrated in strong research designs, such as randomized controlled trials, that hold up to scientific scrutiny. The study by Aggarwal and colleagues in this issue shows an application of probiotics that has increasingly become the subject of research interest for the treatment of acute childhood diarrhoea.
