Official title
Plasma Lipids-dependent Vitamin E Metabolism During Dynamic Hyperlipidemia
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: Obesity is known to lead to diseases such as diabetes and high cholesterol (or fats) in the blood (hyperlipidemia). But no one knows why. Researchers think that high levels of fat in the blood may block important nutrients, such as vitamin E, from reaching places they are needed in the body. Objective: To learn how high-fat meals affect levels of vitamin E in the blood. Eligibility: People aged 18 to 65 with high blood fat levels. Healthy volunteers are also needed. Design: Participants will have 3 or 4 clinic visits in 3 months. The last visit will require them to stay in the clinic for 2 nights. Participants will be screened. They will have a physical exam and blood tests. After this visit, all participants must stop taking any dietary supplements. Those who use them must also stop taking any drugs to lower their blood sugar and blood fats. These participants will have an extra visit for blood tests after 60 days. The next visit will include 2 imaging scans: Magnetic resonance imaging (MRI) of the abdomen. This scan will check for fat in the liver. Dual-energy X-ray absorptiometry (DEXA). This scan measures the levels of body fat. On day 1 of the clinic stay, participants will have 2 set meals, with nothing but water after 10 pm. On day 2, they will drink high-fat shakes at 8 am, noon, and 4 pm. They will have blood draws every hour for 17 hours, and then every 2 hours until 7 am. The blood will be taken from a tube inserted into a vein and left in place for the day. On day 3, they will go home.
