Active clinical trials for "Hypercholesterolemia"

Studies have shown that phytosterols will lower LDL cholesterol. Typical diets can contain between 250 to 500 mg of naturally-occurring phytosterols. Long-term studies with phytosterol-containing products(such as margarines) have not taken into account the amounts of naturally occurring phytosterols in the diet. This means that the effects of small amounts of natural dietary phytosterols on LDL cholesterol are not known. In this study, we will examine the effects of phytosterols across a range of levels. The information will likely be used to further support and possibly extend the current dietary recommendations for phytosterol use.

Healthy and at risk (hypercholesterolemic) subjects consumed during 4 weeks 45 g/d of either olive pomace oil (OPO) or sunflower oil (SO) as the only dietary fat in a randomized, crossover trial. The effects on blood lipids, glucose homeostasis, endothelial function, inflammatory cytokines, oxidative stress biomarkers and anthropometry were measured.

Background: Previous studies report that daily pecan consumption reduces cholesterol in healthy adults while promoting weight maintenance. Purpose: To examine the impact of daily pecan consumption with and without dietary substitution instructions for an 8-week period on markers of health in adults at risk for cardiovascular disease.

To evaluate the lipoprotein kinetics of subjects enrolled in the R1500-CL-1331 clinical trial (NCT02265952) to assess the mechanism by which the evinacumab may affect lipid levels in HoFH subjects.

The objective of the study is to assess the effect of fortified eggs (compared to a non-egg supplemented diet) and intermittent fasting (IF) (compared to a usual care diet) on biomarker profile at 4 months. This will be a 140-participant, 2x2 factorial, randomized clinical trial comparing fortified eggs vs. a non-egg supplemented diet and IF vs. usual care diet through 4 months. Participants will be randomized 1:1:1:1 to the four treatment groups. Participants will have in-person follow-up visits at 1- and 4- months (inclusive of laboratory assessments) in addition to telephone calls at months 2 and 3. A subset of patients (~24 in each egg randomized strata) will undergo microbiome assessment at baseline and at 4 months.

The purpose of this study is to determine the effect of gemcabene on the pharmacokinetics of atorvastatin 80 mg

Study hypothesis: Diet integrated with food prepared with olive, buckwheat, peas and chestnut flour as in PreBIOil product combination can modify the gut microbiota and the cholesterol metabolism. Primary objectives of the study are to assess whether the test product to be able to change: fecal microbiota profile; Plasma cholesterol LDL, total, total LDL and HDL ratio; plasma triglycerides; Apolipoprotein ApoA-I, ApoB, and Lp. Secondary objectives of the study are: anthropometric indices; secondary metabolites of polyphenols in human biofluids; mass spectrometry plasma and urine metabolite profile; blood glucose and fasting insulin levels; 5,6) C-reactive protein (PRC or hsPRC); 7) urinary isoprostane F2; 8) oxidized LDL in plasma. Study Design: placebo-controlled, randomized, double-blind parallel trial. Inclusion criteria: Aged 30-65 years; BMI 20-29,9 kg/m^2. Total Cholesterol 180-240 mg/dl Exclusion criteria: Fasting blood glucose >150 mg/dl; triglycerides >500 mg/dl; uncontrolled hypertension (blood pressure [BP] >160/100 mm Hg under antihypertensive therapy); any long term medical therapy; food intolerances; alcohol intake >5 drinks per day or use of narcotic substances; use of dietary supplements, pro or pre- biotics; special diet; pregnancy, tobacco smoking. Methodology: Determination of eligibility: for each volunteer aged between 30 and 65 years, will undergo to clinical and biochemistry evaluation. Clinical visit, clinical tests, and blood drawing will be performed after an overnight fasting at visit T-1 at the Casa di Cura Eremo di Arco (TN). In this T-1 visit the eligibility will be established and the participants will be randomized to receive supplementation with either PreBIOil biscuit (90g/day) or Control for 8 weeks in a double-blind manner. Clinical tests, blood drawing, and stool and urine collection will be performed during visits at the beginning and end of each treatment period (T0 and T1). A 4 day-food diary record will be collected before visits T0, at the beginning of T0 and before T1. Efficacy Assessments Arterial BP; BMI; ratio of waist to hip circumference; food questionnaires; blood sample analysis (total cholesterol, triglycerides, HDL and LDL cholesterol, oxidized LDL, serum glucose and insulin, C-RP, Apolipoproteins, Isoprostane; urinary and plasma metabolite profiling; fecal microbiota analysis. Safety assessments. Adverse events registration. Statistical analyses. The differences between the two group will be evaluated with univariate and multivariate statistical methods. The medium before and after the intervention will be compared with the General Linear Model (ANOVA) for repeated measures or for paired data. Simple and multiple linear regressions will be performed to determine the relationships between independent variables; also we will run the t-test to evaluate differences in compliance detected in the types of supplementation. The results are expressed as mean +/- SEM and the differences will be considered significant when P <0.05. Duration: Subjects will make three visits (visit T-1, beginning visit T0, and end of treatment period visit T1, week 8 from T0). The treatment duration is 8 weeks; a daily portion of about 90 g of biscuit is introduced.

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 investigators performed a 12-week, randomized, double-blind, placebo-controlled human trial to evaluate the efficacy and safety of Ecklonia cava extract on hyperlipidemia.

Primary Objective: To assess the effects of subcutaneous (SC) doses of alirocumab on the elimination (measured by Fractional Clearance Rate (FCR)) of apolipoprotein B (apoB) in low density lipoprotein (LDL) in adults with mildly elevated LDL-cholesterol (LDL-C). Secondary Objectives: To assess the effects of SC doses of alirocumab on: Various parameters of the metabolism and turnover in plasma of different lipoproteins Plasma lipids concentration: total cholesterol, high density lipoprotein cholesterol (HDL-C), triglycerides, low density lipoprotein cholesterol (LDL-C), apoB, lipoprotein(a) (Lp(a)) Lipoprotein particle size profile PCSK9 (free and total) concentrations in serum To assess safety and tolerability of alirocumab. To assess emergence of anti-alirocumab antibodies. To document serum alirocumab concentrations.
