Filter by:Despite the wide availability of advanced lipoprotein tests, no reference standard exists for Low Density Lipoprotein Cholesterol (LDL-C) due to inherent problems with each of the assays. Newer methods for estimating LDL particle numbers, including nuclear magnetic resonance (NMR) spectroscopy and vertical auto profile (VAP) are currently under investigation. NMR has been proposed as having the best correlation with adverse cardiovascular outcomes. Unfortunately, the accuracy of LDL-C or LDL particle number measurements is currently not monitored by national standardization programs. Direct comparisons between the various testing methods have been limited restricting our ability to accurately interpret and compare values across vendors and lipid parameters. Our hypothesis is that: 1. LDL particle count numbers, as determined by NMR (Liposcience), provides the best estimates of cardiovascular risk. 2. Discrepancies exist between the LDL particle count by NMR and other values as presented by calculated LDLC and directly measured LDL (VAP and ion mobility). The investigators will enroll 100 patients recruited from the Lipid Clinic at the Scripps Center for Integrative Medicine. Each patient will have one blood draw from which four tests will be analyzed. Risks are associated with drawing blood, which will be minimized by using Scripps Clinic Lab technicians. The potential loss of personal health information will be reduced by limiting access to study and lab staff and keeping information password-protected on Scripps servers.
Coronary heart disease and stroke are two main causes of human deaths and is directly related to increased levels of plasma lipids.High total cholesterol and low high density lipoprotein cholesterol concentrations are often associated with endothelium dysfunction and inflammation, which can be followed by atherosclerosis. Rhus coriaria L. (Rhus) with the public name of "Somagh" is a plant species in the anacardiaceae family that is used as a food supplement, spice in Middle East region (Iran, Turkey and Arabic countries). In a double blind randomized placebo-controlled clinical trial, the investigators want to evaluate the effects of Somagh (Rhus coriaria L.) on serum lipid levels of patients with hyperlipidemia.
The purpose of this survey is to determine the incidence rate of cardiovascular (CV) events associated with long-term treatment with and without omega-3 fatty acid ethyl esters (Lotriga Granular Capsules) in high-risk hyperlipidemic patients treated by statin in daily medical practice.
Comparison of the efficacy and safety of Cresnon® and Crestor® in patients with hyperlipidemia - 8-week, active-controlled, open-label, randomized, parallelgroup, fixed-dose, noninferiority, multicenter, phase 4 design
In this study the investigators will examine the effect of the polypill on medication adherence, systolic blood pressure, and LDL cholesterol over a 12 month span.
The primary objective of this study was to evaluate the pharmacokinetics of evolocumab after a single 140 mg subcutaneous (SC) dose in aduts with normal renal function or severe renal impairment or end-stage renal disease (ESRD) receiving hemodialysis.
The purpose of this study is to evaluate the effect of 12 weeks of acupuncture and moxibustion compared with active control, on absolute and percent change from baseline in low-density lipoprotein cholesterol (LDL-C) among those with hyperlipidemia.
Background: - Generalized lipodystrophy can cause high blood fat levels and resistance to insulin. This can lead to health problems including diabetes. Researchers have found that the drug metreleptin improves health in people with this disease. Objective: - To test the safety and effectiveness of metreleptin. Eligibility: - People ages 6 months and older with generalized lipodystrophy who: - have received metreleptin through NIH studies AND - cannot get it through approved or compassionate use mechanisms in their home country. Design: - Participants will come to NIH approximately every 6 months during year one, then every 1 2 years. Financial assistance may be available for travel within the U.S. - At visits, participants will get a supply of metreleptin to take home for daily injections. They will have: - plastic catheter placed in an arm vein. - blood tests, urine collection, and physical exam. - oral glucose tolerance test, drinking a sweet liquid. - ultrasound of the heart, liver, uterus, and ovaries. A gel and a probe are placed on the skin and pictures are taken of the organs. - echocardiogram, which takes pictures of the heart with sound waves. - Resting Metabolic Rate taken. A plastic hood is worn over the head while the oxygen they breathe is measured. - Participants will have up to 3 DEXA scan x-rays per year. - Participants may have: - annual bone x-rays. - liver biopsies every few years. A needle will be inserted into the liver to obtain a small piece. Participants will sign a separate consent for this. - Participants must be seen regularly by their local doctors and have blood tests at least every 3 6 months at home.
Background: - Partial lipodystrophy can cause high blood fat levels and resistance to insulin. This can lead to health problems including diabetes. Researchers have found that the drug metreleptin improves health in people with this disease. Objective: - To test the safety and effectiveness of metreleptin. Eligibility: - People age 6 months and older with partial lipodystrophy who - have received metreleptin through NIH studies and shown improvement AND - cannot get metreleptin other ways. Design: - Participants will come to NIH approximately every 6 months during year one, then every 1 2 years. Financial assistance may be available for travel within the U.S. - At visits, participants will get a supply of metreleptin to take home for daily injections, or it can be shipped to them inside the U.S. They will have: - plastic catheter placed in an arm vein. - blood tests, urine collection, and physical exam. - oral glucose tolerance test, drinking a sweet liquid. - ultrasound of the heart, liver, uterus, and ovaries.

The objective of the study is to assess the effect of two diets with different fat composition on cholesterol metabolism. The study was a randomized cross-over trial where volunteers follow two study periods with different types of meat (lean and fat red meat) separately by a ten days wash-out period. At the beginning of the study and after the study periods the following parameters are determined: anthropometric (weight, waist, circumference and body mass index), blood pressure, dietary (72-hours dietary registry) and exercise assessments and biochemical analysis (total cholesterol, triglycerides, HDL cholesterol, LDL cholesterol, apolipoprotein A1, apolipoprotein B, iron, transferring, ferritin, uric acid, glucose, HbA1c and insulin). Serum concentration of non cholesterol sterols (sitosterol, campesterol, stigmasterol, desmosterol and lanosterol) and oxysterols (24S-hydroxycholesterol, 27-hydroxycholesterol and 7α-hydroxycholestenone) were measured by High Performance Liquid Chromatography tandem Mass Spectrometry in these subjects throughout along the study in order to demonstrate the effect of different red meat on the hepatic metabolism of cholesterol.
