Brief Summary:
Some of the fat (triglyceride) from the food humans eat gets stored in the bowel. This triglyceride can then be released into the blood when another meal is consumed or in response to hormones. How the gut hormone glucagon-like peptide-2 (GLP-2) releases the triglyceride from the gut is not known. The research team in this study is interested in finding out how teduglutide (a degradation resistant form of GLP-2) releases stored triglyceride from the gut by studying samples from patients undergoing endoscopy and small bowel biopsy.

Condition or disease Intervention/treatment Phase
Hyperlipidemias Drug: Teduglutide Drug: Placebo Phase 2 Phase 3

Detailed Description:
The release of stored enteral lipids will be investigated in 30 patients undergoing upper gastrointestinal endoscopy and duodenal biopsy for clinical indications. Patients undergoing the procedure will be recruited. Participants will have a high fat liquid meal as breakfast. 5 hours later, participants will be randomly assigned to receive either a subcutaneous injection of placebo (n=15) or a subcutaneous injection of the Health Canada approved glucagon-like peptide-2 (GLP-2) analogue (teduglutide, Revestive®, Shire Canada)(n=15 different subjects). 1 hour later, a duodenal biopsy specimen will be obtained from 2-3 sample sites,snap frozen in dry ice and stored at -80°C for further analysis.
