Summary
Study start date: September 1, 2011
Actual date on which the first participant was enrolled.Each subject will be studied twice 4-6 weeks apart in random order in this single blinded study. A nasoduodenal tube will be sited under fluoroscopic guidance the day prior to the study.In study A they will receive intraduodenal intralipid (20% at 60 ml/hour) alongside 60 ml/hour of 20% dextrose or fructose for 15 hours starting at 4am. In study B they will receive 60 ml/hour of intraduodenal intralipid with 60ml/hour of normal saline for 15 hours from 4am. A pancreatic clamp (octreotide with replacement glucose, insulin, glucagon and growth hormone) will be started at 7am. From 9am an iv bolus of deuterated-glycerol (d5-glycerol) along with a regular infusion of deuterated leucine (L-[5,5,5-2H3]. Regular blood samples will be drawn to assess lipoprotein kinetics.
