Active clinical trials for "Hyperlipidemias"

Low and very low carbohydrate diets, such as the Atkins' Diet, have recently gained attention for their potential health benefits from weight loss and have gained some scientific support from a growing number of studies. Benefits have been noted in relation to raised "good" cholesterol, lower "bad" cholesterol and triglycerides. Other studies have shown an advantage in substituting vegetable fat for carbohydrate in insulin resistant individuals and in some instances in type 2 diabetes where improvements were seen in "good" cholesterol and blood sugars. At the same time, our research have been exploring diets containing less processed carbohydrates and other components which in combination (portfolio diet) have a similar cholesterol lowering effect to drug therapy. Therefore we wish to determine whether our cholesterol-lowering components (portfolio diet) should be incorporated into lower carbohydrate diets especially to preserve "good" cholesterol and lower "bad" cholesterol for decreasing the risk of heart disease.

The purpose of this study is to evaluate the long term effectiveness of the dietary portfolio, consisting of viscous fibers, soy products, nuts and plant sterols, as well as the effects of removing single food components from the dietary portfolio on cholesterol reduction and other cardiovascular risk factors.

A 16 week open-label study with subjects receiving background metformin monotherapy. 150 subjects randomized 1:1:1 to receive 1 of the following: open-label colesevelam HCl, open label rosiglitazone, or open-label sitagliptin.

Included in this study will be patients with HIV and being treated with highly active antiretroviral medications (HAART) including protease inhibitors (PI) or non-nucleoside reverse transcriptase inhibitors (NNRTI). Protease inhibitors and non-nucleoside reverse transcriptase inhibitors are very common medications in HIV treatment and are usually given with other medications as part of a standard treatment for HIV (HAART). We hope to learn more about how the levels of cholesterol-and triglyceride-carrying particles (lipoproteins) are affected by a nutritional supplement, L-Carnitine, in HIV-positive patients treated with antiretroviral medications.

The purpose of this study is to evaluate the effects of Crestor (rosuvastatin) and (Lipitor) atorvastatin on urinary protein excretion over 1 year in non-diabetes with moderate proteinuria and hypercholesterolaemia.

The purpose of this study is to investigate the benefits of combination niacin ER/lovastatin in patients receiving standard care who are not at LDL goal per ATP III guidelines.

The purpose of this study is to determine whether addition of strawberries to a dietary portfolio of cholesterol-lowering foods will improve compliance and so increase the effectiveness of the dietary portfolio in lowering cholesterol and improving cardiovascular risk factors.

Mixed or combined hyperlipidemia is a common metabolic disorder characterized by both hypercholesterolemia and hypertriglyceridemia. Statins and fibrates have complementary mechanisms and can be coadministered to patients with mixed hyperlipidemia. The overall objective of the study is to compare the efficacy and safety of combining fenofibrate and simvastatin versus atorvastatin monotherapy in patients with mixed hyperlipidemia at risk of cardiovascular diseases.

The purpose of the study is to measure the effect of the amlodipine/atorvastatin combination pill in reducing both elevated blood pressure and cholesterol levels to levels suggested by guidelines

The purpose of this study is to determine the effect of fish oil and the antioxidant alpha lipoic acid on factors in the blood that are associated with the progression of Alzheimer's Disease (AD).
