Plain English Summary
Background and study aims
Diarrhoea rarely results in death in adults, but can affect a family’s resources through extra health care costs and loss of wages. The current treatment (oral rehydration solutions [ORS]) reduces dehydration in patients but does not reduce the time to resolution of the diarrhoea. The aim in this study is to find out whether a bioactive solution can reduce the time an individual has diarrhoea.
Who can participate?
Adults with acute, non-infectious diarrhoea for up to 48 hours
What does the study involve?
Participants will be randomly allocated to one of two groups: ORS and water (control group) or a bioactive solution added to the ORS (test group) on day 1. They will be monitored for 5 days to find out the time to resolution of the diarrhoea.
What are the possible benefits and risks of participating?
A possible benefit is a shorter time to resolution of the diarrhoea. A possible risk is a reaction to the bioactive solution.
Where is the study run from?
Community health clinic of Universidad Centroamericana de Ciencias Empresariales (Nicaragua)
When is the study starting and how long is it expected to run for?
From August 2011 to May 2012

Diarrhoea in adults
Patients will be randomly allocated to oral rehydration solution (ORS) and bioactive polyphenol solution or ORS and water on day 1 and then monitored for 5 days to determine the time for resolution of diarrhoea and any changes to gastrointestinal symptoms.
Primary outcome measure
Resolution of diarrhoea, assessed as the time that stool had a Bristol Stool Scale ranking of 4 or less
Secondary outcome measures
Change in ranking of abdominal pain and bloating between day 1 and day 5 and any adverse events, measured with the Visual Analogue Scale of 0 to 10
