Intervention/exposure
Study type

Treatment: Other
Comparator / control treatment
High amylose maize starch, 10 g mixed per 200 ml ORS and consumed every hour and after every loose stool until stool consistency becomes formed or for a total of 72 hours.

Outcomes
Primary outcome [1] 279501 0
Duration of diarrhoea defined as time from commencing therapy to first formed stool or 12 hour period without stool. Stool form is assessed by a technician according to the Bristol stool form scale, and formed stool is defined as type IV stool in the scale.
Timepoint [1] 279501 0
Continuous variable, time from 0-72 hours
Primary outcome [2] 279502 0
Stool weight in first 24 hours and total diarrhoea stool weight. Stool is collected in lined plastic containers and weighed every twelve hours on an electronic scale by a technician.
Timepoint [2] 279502 0
Measured every 12 hours till recovery or 72 hours
Secondary outcome [1] 287762 0
Need for unscheduled (i.e. after initial four hour rehydration period) intravenous fluids. Intravenous fluids are commenced if dehydration persists or worsens at the end of the first six hours of therapy, or dehydration reappears any time during subsequent course despite adequate intake of ORS.
Timepoint [1] 287762 0
Every 12 hour period till recovery or 72 hours.
Secondary outcome [2] 287763 0
Proportion of patients who recover from diarrhoea at 24 hours and at 48 hours. Recovery is defined as the passage of two consecutive formed stools (type IV on the Bristol stool form scale).
Timepoint [2] 287763 0
24 hours and 48 hours
Secondary outcome [3] 287764 0
Adverse events - serum sodium <120 mmol/L, serum creatinine >4 mg/dL, persistent vomiting
Timepoint [3] 287764 0
24 hours

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Consecutive patients presenting to the Emergency services with acute dehydrating diarrhoea will be evaluated by the medical officer and offered inclusion in the study if suitable. The agents used for treatment in intervention and comparator arms are packed in sealed opaque envelopes which are sequentially numbered based on the randomization code. Neither the treating team nor the assessment team nor the patient is aware of the specific treatment received by each patient.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block randomization, sequence generated by a computer program
Masking / blinding
Blinded (masking used)

Summary
Brief summary
The hypothesis behind the study is that high amylose maize starch acetate, a functional food that delivers acetate and other short chain fatty acids to the colon, will significantly shorten duration of diarrhoea and reduce diarrhoea stool output in patients with acute gastroenteritis. Short chain fatty acids are normally found in the lumen of the colon in high concentrations, being formed there by fermentation of carbohydrate. Reduction of colonic short chain fatty acids in diarrhoea is likely to prolong diarrhoea and slow recovery. High amylose maize starch, naturally found in several corn serovars, reduces diarrhoea in adults and children with gastroenteritis. We hypothesize that high amylose maize starch acetate, that delivers acetate to the colon besides undergoing fermentation to short chain fatty acids, will shorten diarrhoea to a greater extent than high amylose maize starch. In this double-blind randomized controlled clinical trial, adults with diarrhoea and dehydration will receive standard treatment including oral rehydration solution and early feeding, and in addition will receive either high amylose maize starch acetate or high amylose maize starch. Severely dehydrated patients will first receive intravenous fluids for rehydration followed by randomization. Duration of diarrhoea, diarrhoeal stool weight, need for unscheduled intravenous fluids will all be recorded.
