Filter by:Aim 1: To determine whether therapy with Alirocumab, compared to pre-treatment, will effectively improve carotid atherosclerotic plaque characteristics by reducing Ktrans and LRNC size. To achieve this goal, we will (a) enroll 30 subjects who are intolerant to high intensity statin therapy and only able to tolerate low potency statin or low weekly dose of high potency statin and have LDL-C ≥70 mg/dl; (b) initiate alirocumab at 150mg subcutaneously injection every 2 weeks; (c) perform carotid DCE-MRI scans at baseline, 3, 6 and 12 months; (d) perform quantitative analysis for vascular inflammation and plaque LRNC volume and other plaque characteristics; (e) compare vascular inflammation and LRNC volume between pre- and post-alirocumab at 3, 6 and 12 months. Aim 2: To examine associations between reductions in atherogenic lipids (LDL-C, Lp(a), non-HDL-C) and changes in atherosclerotic plaque characteristics. To achieve this goal, we will (a) perform laboratory assessments of lipids, lipoproteins and apo-lipoproteins at baseline and during the study; (b) compare lipids, lipoproteins and apo-lipoproteins levels between pre- and post-alirocumab; (c) correlate reductions in atherogenic lipids with changes atherosclerotic plaque characteristics.
Animal studies have found that vitamin K-dependent proteins matrix Gla protein and osteocalcin beneficially influence lipid and glucose metabolism, respectively. However, this concept has not been tested in humans at risk for dyslipidemia and diabetes risk. Vitamin K supplementation presents an opportunity to test the hypothesized link between the vitamin K-dependent proteins and markers of lipid and glucose metabolism. The investigators will conduct an 8-week vitamin K intervention (to manipulate carboxylation of matrix Gla protein and osteocalcin) and determine its effects on markers of dyslipidemia and diabetes risk. Sixty obese children will be randomly allocated to either the control group receiving placebo or the low-dose (45 mcg/d) or high-dose group (90 mcg/d) receiving vitamin K (menaquinone-7).
The objective of this study is to evaluate the efficacy and safety of ARI-3037MO compared to placebo in reducing low-density lipoprotein cholesterol (LDL-C) levels in subjects with dyslipidemia.
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. 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.
Vitamin D deficiency is associated with a heightened risk for developing type 2 diabetes, hypertension, and osteopenia/osteoporosis. Vitamin D is made in the skin when it is exposed to sunlight and it is also obtained from the diet and dietary supplements. Older people, individuals with high skin pigmentation, obese and sedentary individuals have low levels of Vitamin D because pigmentation blocks Vitamin D production in the skin, aging and physical inactivity are associated with reduced exposure to sunlight, and obesity is associated with the storage of Vitamin D in fat preventing its utilization by muscle, bone and other tissues that require its metabolic action. These conditions are also associated with heightened risk for developing type 2 diabetes, glucose intolerance, hypertension, and osteopenia/osteoporosis in older and obese individuals. This is particularly heightened in older women who tend to have increased body fat, are more physically inactive and are at high risk for central obesity and its metabolic consequences of diabetes, hypertension and osteoporosis.
Since uncontrolled observational studies first linked fructose to the epidemic of obesity almost a decade ago, it has become a focus of intense concern regarding its role in the obesity epidemic and increasing burden of cardiometabolic disease. Despite the uncertainties in the evidence, international health organizations have cautioned against moderate to high intakes fructose-containing sugars, especially those from sugar sweetened beverages (SSBs). To improve the evidence on which nutrition recommendations are based, the investigators propose to study of the role of fructose-containing sugars in the development of overweight/obesity, diabetes, hypertension, gout, and cardiovascular disease, by undertaking a series of systematic syntheses of the available prospective cohort studies. Prospective cohort studies have the advantage of relating "real world" intakes of sugars to clinically meaningful disease endpoints over long durations of follow-up. The findings generated by this proposed knowledge synthesis will help improve the health of consumers through informing recommendations for the general public, as well as those at risk of diabetes and cardiovascular disease.
Study design - Multicenter, double-dummy, double-blinded, randomized, Phase 4 study - Patients will be randomized to either a study group or a control group in a 1:1 ratio, and will be orally administered the assigned drugs Study Objective -The study is designed to demonstrate that efficacy and safety of morning dosing of Simvast Controlled Release (CR) Tab is not inferior to evening dosing of Zocor Tab in patients with stage 3,4,5 chronic kidney disease with hyperlipidemia Primary objective -to assess the percent change of LDL-C at Week 8 from baseline in Chronic Kidney Disease(CKD) stage 3,4,5 with hyperlipidemia subjects.
The objective of this study is to determine if the administration of a cholesterol lowering drug like ezetimibe will reduce circulating omega-3 fatty acid (ALA) levels in patients with heart disease and hypercholesterolemia. The investigators hypothesize that their data will discover that patients receiving ezetimibe require additional dietary supplementation with omega-3 supplements to insure that these beneficial fatty acids are available to these patients.
The purpose of this study is to evaluate the effects of a diet supplementation with plant sterol esters on serum lipids, plant sterol concentrations and monocyte subpopulations.
Hyperlipidemias are frequently associated with and are considered an important cause of erectile dysfunction in men. This association has been attributed to the impairment of blood flow through endothelium-dependent relaxation in smooth muscle cells of corpus cavernosum. Basic science and human research suggest that the vascular pathophysiology of male and female sexual dysfunction may be similar, as the first phase of the female sexual response is mediated by a combination of vasocongestive and neuro-muscular event which include increased clitoral length and diameter, as well as increased vaginal lubrication, wall engorgement and luminal diameter. The investigators have shown that women with hyperlipidemia had a higher prevalence of sexual dysfunction as compared with age-matched women without hyperlipidemia. The aim of this study was to asses the effect of anti-hyperlipidemic drugs (fenofibrate and rosuvastatin, single or in combination) on validated indices of sexual function in hyperlipidemic men and women with sexual dysfunction at baseline.
