Filter by:This randomised controlled trial studies the effect of a commercially available nutritional supplement on cholesterol levels in people with metabolic syndrome and elevated cholesterol levels.
Regular consumption of a beverage containing β-cryptoxanthin (b-Cx) and plant sterols (Ps) has been shown to exert a synergic effect in reducing cardiovascular risk and bone remodeling markers (formation and resorption). The present project aims to assess the influence of technological treatment and genetic variability on the bioavailability and the health effects of the added components (Ps, b-Cx), in particular to their potential role in prevalent disorders.In vitro and in vivo studies will be carried out to this effect. In vitro and in vivo studies (human intervention study) will be performed and cardiovascular, bone turnover and inflammation markers will be evaluated. Additionally, an in vitro colonic fermentation model and cell cultures will be used to explore anticarcinogenic effects and potential cytotoxicity.
The purpose of this study is to evaluate the low density lipoprotein cholesterol (LDL-C) lowering effect of Bococizumab (PF-04950615;RN316) administered subcutaneously at every two weeks (Q14D) in hypercholesterolemic Japanese subjects whose LDL-C is not controlled by a stable dose of atorvastatin, or who are naïve to a treatment by lipid lowering drug and whose LDL-C is not controlled.
Probiotics have been proposed for the treatment of dyslipidemia. the investigators aimed to evaluate efficacy, tolerability and safety of a new symbiotic formulation containing a combination of probiotic and prebiotics and amine in the treatment of children affected by familial hypercholesterolemia (FH).
This study aims to characterize the single dose pharmacokinetics of PF-04950616 following subcutaneous injection to the abdomen, upper arm or the thigh.
This project will address the important area of childhood obesity and the risk of cardiovascular disease associated with obesity. This is a serious health concern since children who are overweight or obese are prone to other medical conditions including high blood pressure, abnormal lipid profiles,and type 2 diabetes. Although exercise and nutrition programs are recommended, evidence for the efficacy of these programs in improving cardiovascular health is lacking. Specific Aims: a) improve cardiovascular risk factors, b) increase physical fitness levels, c) improve lean body mass, d) enhance QOL of the child e) influence adherence rates to exercise and a healthy lifestyle change both during and beyond the conclusion of the program. Hypothesis 1a: Compared to baseline and matched controls, children randomized to a 10 week multidisciplinary fitness and nutrition program will show significant improved levels of cardiovascular risk factors. Specific Aim 2: To determine if a multidisciplinary fitness and nutrition program, when compared with a matched, WLC group will show a change in whole body assessment including a decrease in fat mass, an increase in percent lean body mass, and a decrease in percent body fat, as measured utilizing dual-energy X-ray absorptiometry Hypothesis 2a: Compared to baseline and matched controls, children randomized to a 10 week multidisciplinary fitness and nutrition program will show improved whole body assessments including. Specific Aim 3:To determine if a multidisciplinary fitness and nutrition program, when compared with a WLC group will show improved levels of fitness. Hypothesis 3a: Compared to baseline and matched controls, children randomized to a 10 week multidisciplinary fitness and nutrition program will show significant improvements in fitness including.
Primary Objective: To demonstrate the reduction of low-density lipoprotein cholesterol (LDL-C) by a regimen of Alirocumab including a starting dose of 150 mg every 4 weeks (Q4W) as add-on to non-statin lipid modifying background therapy or as monotherapy in comparison with placebo in participants with primary hypercholesterolemia not treated with a statin. Secondary Objective: - To evaluate the effects on other lipid parameters of Alirocumab 150 mg Q4W versus placebo. - To evaluate the safety and tolerability of Alirocumab 150 mg Q4W. Alirocumab 75 mg Q2W was added as a calibrator arm.
Limonoids are compounds found in citrus juices, seeds and peel. Some research shows that they reduce blood cholesterol and also reduce the incidence of several forms of cancer. Although these compounds are part of the natural human diet, the dose required to provide health benefits and the risks associated with the intake of high doses by humans have not been studied. This study will examine metabolism, safety, lipid-lowering and anti-inflammatory effects of limonoids. The dose of limonoids in this study is equivalent to that found in six 8 oz glasses of orange juice per day. The investigators hypothesize that limonin glucoside supplementation will reduce total cholesterol, LDL cholesterol, ratio of LDL and HDL cholesterol, number of LDL particles, and serum markers of inflammation.
Highly active antiretroviral therapy (HAART) is able to cause lipid metabolism and glucose homeostasis alterations, which are associated to the redistribution of body fat. Alterations in lipid and carbohydrate metabolism contribute to the development of a highly atherogenic profile, which together with altered fibrinolysis markers and increased presence of proinflammatory cytokines in blood (especially tumor necrosis factor alpha) that comes associated to the success of HAART can cause the development of accelerated atherosclerosis. Docosahexaenoic acid (DHA) is a polyunsaturated fatty acid that has demonstrated its ability to reduce triglyceride levels; modify cholesterol fractions and increase the size of LDL particles thereby configuring less atherogenic plasma profile. Additionally, administration of DHA has shown antiinflammatory and hypotensive activity, which contributes to reduce the risk of cardiovascular complications in these patients. At a molecular level, DHA acts as a stimulator of the nuclear receptor PPAR-gamma, which has been described to induce an increase in adipocyte differentiation. Furthermore, the anti-inflammatory effects induced by DHA, can decrease the elevated levels of TNF-alpha, which has been implicated in the pathogenesis of body fat redistribution in HIV infected patients undergoing HAART. Therefore, the hypothesis of this project is that DHA will be able to produce lipid-lowering, anti-inflammatory, hypotensive and profibrinolytic effects, which all together should improve atherogenic profile of patients with HIV-1 infection receiving HAART. In addition, their proprieties as PPAR agonist can improve the redistribution of body fat present in many of these patients. The study of the activity of DHA on dendritic cells and monocytes should indicate the absence of immunosuppressive effect of DHA in the context of HIV-1 infection. In summary, DHA is a natural product, from the omega 3 polyunsaturated fatty acids, the therapeutic properties of which have been described in recent years and has shown cardio-vascular and metabolic beneficial effects, without recognized side effects. The highly purified DHA administration at high doses could be able to reverse, at least partially, lipid abnormalities associated with HAART and to exert a beneficial effect on fat redistribution in HIV-infected patients treated with HAART. To ensure non deleterious immunological treat in these sensitive poly-medicated patients, substantial changes in the functionality of dendritic cells and monocytic will be studied.
Background: Lipid lowering response to weight loss in subjects with genetic hyperlipidemias and overweight or obesity and its effect on cholesterol metabolism has not been studied. Objective: To explore the effects of weight loss on lipid values and cholesterol metabolism, by measuring circulating non-cholesterol sterols, in overweight or obese subjects with genetic hypercholesterolemias. Design: The investigators conducted a 6-months weight loss intervention in subjects with the diagnosis of familial hypercholesterolemia (FH) or familial combined hyperlipidemia (FCHL), body mass index >25 kg/m2, steady weight (±3 kg in the last 3 months) and absence of lipid lowering drugs in the previous 5 weeks. They were advised to follow a hypocaloric diet with a deficit of 600 kcal (30% fat, 15% protein, and 55% carbohydrates) per day as calculated from the person's resting energy expenditure and activity level. Anthropometric data, biochemical analysis including lipids, apolipoproteins and non-cholesterol sterols were evaluated at baseline, 3 months and 6 months.
