Comparing Soybean Oil-Based (Intralipid) With an Olive Oil-Based (ClinOleic) Lipid Emulsion on Healthy Volunteers (TPN1)

December 18, 2014 updated by: Guillermo Umpierrez, Emory University

Randomized Study Comparing Soybean Oil-Based (Intralipid) With an Olive Oil-Based (ClinOleic) Lipid Emulsion: Effects on Endothelial Function, Inflammatory Markers, Oxidative Stress, Immune Function, Autonomic Nervous System, Insulin Sensitivity and Carbohydrate Metabolism

Many patients in the hospital who are malnourished or not eating received intravenous feeding or total parenteral nutrition (TPN). Despite improving nutrition, TPN may increase the risk of infections and hospital complications. We do not know why TPN increases hospital complications, but it may be caused by the high sugar or fat content in TPN solutions. The investigators believe that the high sugar and high fat content can limit the ability to fight infections and produce stiffness of blood vessels. This study will compare the effect of high sugar, high fat content or both on blood sugars, blood vessel function, on blood vessel function. The investigators will also compare the effect of different fats (olive oil and soybean) in the TPN solution on the risk of infection and blood vessel function on a total of 12 healthy subjects.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Flow Mediated Dilation
Time Frame: Baseline
Endothelium-dependent brachial artery flow-mediated dilation (FMD) was assessed. Ultrasound images of the brachial artery were obtained and arterial diameters were measured with customized software. Brachial artery FMD was calculated as (hyperemic diameter - baseline diameter)/baseline diameter × 100.
Baseline
Flow Mediated Dilation
Time Frame: 4 hours after infusion
Endothelium-dependent brachial artery flow-mediated dilation (FMD) was assessed. Ultrasound images of the brachial artery were obtained and arterial diameters were measured with customized software. Brachial artery FMD was calculated as (hyperemic diameter - 4 hour diameter)/4 hour diameter × 100.
4 hours after infusion
Flow Mediated Dilation
Time Frame: 24 hours after infusion
Endothelium-dependent brachial artery flow-mediated dilation (FMD) was assessed. Ultrasound images of the brachial artery were obtained and arterial diameters were measured with customized software. Brachial artery FMD was calculated as (hyperemic diameter - 24 hour diameter)/24 hour diameter × 100.
