Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A 3 x 3 double blind crossover study examining butyrylated high amylose maize starch at 3 dose rates (a) 5 g/d (b) 20 g/d (c) 40 g/d. There are 3 intervention periods of 14 days with a 7 day 'wash out' period between each intervention. The starch is to be ingested orally by way of combination (starch plus long life milk).
Intervention code [1] 264529 0
Treatment: Other
Comparator / control treatment
The butyrylated high amylose maize starch will be compared at 3 different doses (5 g/d, 20 g/d and 40 g/d).
Control group
Dose comparison

Outcomes
Primary outcome [1] 266697 0
To quantify the release of butyrate in the colon. Butyrate concentrations in faecal samples will be analysed using standard distillation procedures and gas chromatography.
Timepoint [1] 266697 0
At the beginning and end of each 14 day test period.
Primary outcome [2] 266698 0
To determine the effects of consumption of the 3 doses of butyrylated high amylose maize starch on FAP patients' gastrointestinal quality of life using a validated assessement tool for evaluating the quality of life and distress for gastrointestinal symptoms (Eypasch et al., 1995 Gastrointestinal quality of life index: development, validation and application of a new instrument; British Journal of Surgery, 82, 216-222.)
Timepoint [2] 266698 0
At baseline and the end of each test period.
Secondary outcome [1] 276213 0
To examine the normal diet of FAP patients using repeated 24 hour diet diaries which will be collected for 2 weekdays and 1 weekend day.
Timepoint [1] 276213 0
At baseline and during the 2 washout periods.

Summary
Brief summary
The objectives of this pilot study are to determine the extent to which large bowel bacteria are capable of releasing esterified butyrate in FAP patients and to determine the acceptability of butyrylated high amylose maize starch in this participant group. This study will consist of three double blinded randomised cross over studies and the objectives will be determined by feeding 3 different doses of the butyrylated high amylose maize starch to FAP patients and measuring butyrate levels in their faeces. This study will provide information on the optimal dose for FAP patients to release esterified butyrate which will be used in a major clinical trial.
