Filter by:Familial hypercholesterolemia (FH) is the most frequent genetic lipoprotein disorder associated with premature CAD. In Canada, the burden of disease is estimated to be approximately 83,500 patients. The goal of this initiative is to create a registry of subjects with FH across Canada. Rare diseases of lipoprotein metabolism are also included. Using a "hub and spoke" model, the registry extends in various communities to link primary care physicians with provincial academic centers. The registry includes clinical, biochemical and demographic information. Specimens (plasma/serum and DNA) are collected for biobanking. The "local" portion of the registry is available for clinicians to manage patient care, and identify relatives for screening and treatment (cascade screening). The Canada-wide registry, which is completely anonymized, will be made available to provide advice to general practitioners and to support collaborative studies in biomedical, clinical, health outcomes and health economics research. The data extracted for the provincial portion of the database will allow administrative database research that will provide important information to key stakeholders and permit allocation of resources. It will also allow a sound and uniform rationale for the use of novel therapeutic agents and provide expert advice to regulatory agencies. At the Canadian level, the database will allow clinicians and researchers to determine the burden of disease and the long-term effects of treatment. Through the creation of a Canada-wide network of academic clinics, integrating lipid specialists, endocrinologists and cardiologists, the Canadian FH registry will lead to significant benefits for FH patients, clinicians and researchers, biopharmaceutical industry and government.
The CASCADE-FH Registry is a national, multi-center initiative that will track the therapy, clinical outcomes, and patient-reported outcomes over time. The registry represents a collaboration between The Familial Hypercholesterolemia Foundation, the Duke Clinical Research Institute, lipid specialists, cardiologists, primary care providers, quality improvement personnel, and patients, all aiming to increase FH awareness, promote optimal disease management, and improve FH outcomes.
The objective of this project is to establish the current prevalence of cardiovascular disease in adult subjects suffering from genetically diagnosed HF, and to know the impact that drug treatment has course in cardiovascular disease when compared with that of their affected parents with a much longer period of exposure to hypercholesterolemia
This repository will establish for the first time a system to carefully assess and monitor over time the general health and the amount of cholesterol in the arteries of U.S. children and adults with homozygous familial hypercholesterolemia (hoFH). Patients with this very rare disorder have very high blood levels of cholesterol from birth due to the inheritance of an abnormal gene from each parent. As a result, if untreated, heart attacks and sudden death occur in childhood. Treatments such as LDL-apheresis and liver transplant will lower the cholesterol level, but the best treatment and the best way to monitor the effect of the treatment on the arteries are unknown. The collection of clinical data and blood for analysis of known and yet-to-be discovered markers and predictors of arterial disease will yield new information about the natural history of the disorder and response to treatment. The repository will greatly aid the development of specific protocols that seek to learn more about this disease and new therapies.
Familial hypercholesterolemia (FH), an inherited disorder of lipoprotein metabolism, is a risk for early cardiovascular disease (CVD). This autosomal dominant disease is characterized by markedly elevated plasma concentrations of low density lipoprotein (LDL) and total cholesterol (TC). The purpose of this study is to compare the effect of a diet low in saturated fats but enriched either with rapeseed oil (RO) or sunflower oil (SO) in children and adolescents with FH on serum lipoproteins.
Study Title: Evaluation of chylomicrons metabolism in sub-clinical atherosclerosis in patients whit Heterozigous Familial Hypercholesterolemia (FH) treated with statin plus ezetimibe. Background: Coronary artery calcification (CAC) is a marker of sub-clinical coronary atherosclerosis which correlates with higher risk of clinical events. It was already demonstrated that CAC is more prevalent in patients with FH compared with normal individuals. A number of studies demonstrated that plasmatic removal of chylomicrons is defective in patients with atherosclerosis. Despite the fact that is still controversial whether this impairment occurs in patients with HF when compared to normal controls, the kinetics of chylomicrons has not been studied in HF patients with and without atherosclerosis and more important, it is not clear if those changes may be observed in the sub-clinical disease, as reported for CAC in asymptomatic individuals. Previous studies have demonstrated the inverse correlation among LDL-C levels and the removal of remnants chylomicrons using artificial chylomicrons technique. It is also well known that high doses of more potent statins are more effective to remove chylomicrons from the plasma due to better expression of LDL-C receptors through plasma LDL-C reduction. It was not evaluated yet if the association of ezetimibe and statin, enhancing LDL-C receptors expression in the liver would enhance the efficacy of the monotherapy with statins to remove artificial chylomicrons in patients with HF. Study design: Open, randomized, single-blinded study in which twenty six outpatients from the Lipids Clinical Unit at the Heart Institute (INCOR), University of São Paulo, previously diagnosed with FH according to US MED PED criteria, without history of CD and a CAC evaluation by MSCT (Multiple Sensors Computed Tomography) in the previous year will be compared to 26 control individuals matched by age and sex collected from the database of the Lipids Metabolism Laboratory. Patients will be randomized to receive simvastatin 40 mg as monotherapy or in combination with ezetimibe 10 mg and will undergoing three kinetics studies to demonstrate the effects of simvastatin 40 mg on the kinetics of the chylomicrons along with other laboratorial dosages ( lipid fractions, hepatic enzymes and CK). The primary endpoint of this study is to evaluate if there is any correlation among the reduction of the plasma clearance of chylomicrons by the artificial chylomicrons technique and the presence of sub-clinical atherosclerosis; the secondary endpoint is to evaluate if ezetimibe/simvastatin enhances the effects of simvastatin alone in the removal of chylomicrons in patients with HF.
