Plain English Summary
Background and study aims
Diarrhoea is a leading cause of death in children, and results in health decline and time lost at work for adults. Oral rehydration solution (ORS) is the standard of care for individuals with non-infectious diarrhoea. It reduces the dehydration caused by diarrhoea, but does not reduce the time to resolution of diarrhoea. The aim of the study is to test whether adding a novel polyphenol solution to ORS might reduce the time to resolution of the diarrhoea compared with the resolution time with ORS alone.
Who can participate?
Adults and children with diarrhoea for less than 48 hours
What does the study involve?
Participants will receive ORS plus the polyphenol solution or ORS plus water once at the start of 2 days and the resolution of diarrhoea and other intestinal symptoms will be recorded.
What are the possible benefits and risks of participating?
The benefits are the reduction of the duration of diarrhoea with no side-effects. The risk is that a patient might have an adverse event to the polyphenol solution.
Where is the study run from?
Community clinic associated with the Universidad Centroamericana de Ciencias Empresariales (Nicaragua)
When is the study starting and how long is it expected to run for?
From February 2010 to December 2010.

Acute diarrhoea (for less than 48 hours)
1. Oral rehydration solution and bioactive solution on day 1 and then oral rehydration solution and water (placebo) on day 2
2. Oral rehydration solution and water (placebo) on day 1 and then oral rehydration solution and bioactive polyphenol solution on day 2
Primary outcome measure
Resolution to diarrhoea, assessed as the time from ingestion of the solution to when an individual produced a stool with a Bristol Stool Scale ranking of 4 or less.
Secondary outcome measures
1. Defecation urgency, ranked from 0 (none) to 10 (extreme) at the various time intervals by patients (adults) and caregivers (for children)
2. Bloating or gas, ranked from 0 (none) to 10 (extreme) at the various time intervals by patients (adults) and caregivers (for children)
3. Abdominal pain at 30, 60, 90 and 120 minutes after consumption of the solutions on day 1 and day 2; pain was ranked from 0 to 10 on the Visual Analogue Scale
