Filter by:Patients undergo 4-week placebo lead-in and diet period, and 12-week treatment period. Clinical efficacy and safety is evaluated at weeks 4, 8 and 12. This study takes approximately 18 weeks for an individual patient to complete including post-visit at week 14.
This study examined the effects of 2.6 g/d of phytosterol ingestion on LDL cholesterol metabolism. It is expected that this dose will significantly reduce LDL cholesterol after 12 weeks of supplementation.
The retinal vasculature is morphologically and functionally related to the cerebral vessels due to its common origin from the internal carotid artery. A recent study demonstrated that endothelium-dependent vasodilation of the retinal vasculature is impaired in patients with essential hypertension, which is a strong risk factor for stroke. Furthermore, AT1-receptor blockade was demonstrated to improve retinal endothelium-dependent vasodilation in these hypertensive patients. Hypercholesterolemia is also a risk factor for ischemic stroke and impairment of endothelial function has been observed in various vascular beds in hypercholesterolemic patients, including the coronary and the forearm vasculature. Whether endothelial function of the retinal vasculature is impaired in patients with hypercholesterolemia has not yet been investigated. In patients with stroke, AT1-receptor blockade and angiotensin-converting enzyme inhibition have beneficial effects on clinical outcome. Alterations of endothelial function of the cerebral vasculature might be one pathogenetic factor for the beneficial clinical outcome. To further address this issue, the present study was designed to test the hypothesis that endothelium-dependent vasodilation of the retinal vasculature is impaired in hypercholesterolemic patients and that endothelial function can be improved by AT1-receptor blockade.
The objective of this study is to assess the effectiveness of an atorvastatin treatment regimen involving starting doses between 10 and 80 mg, followed by a single-step titration (except for subjects started at 80mg), if required
The aim of this study is to see if plant sterols are effective at lowering blood cholesterol levels in Chinese people. The study will be done with Chinese colleagues based at Peking University in Beijing with whom our Institute has a well-established collaboration. The study will be randomised, placebo-controlled and double-blind. The total study period for participants will be an average of seven weeks comprised of a two-week placebo run-in period and a five-week follow-up on randomised treatment. Randomised treatment will comprise either placebo, low- or standard-dose plant sterol. The primary outcome for the study will be blood cholesterol levels.
This study will evaluate the lipid-lowering effect and safety of colesevelam therapy administered to heterozygous familial pediatric patients 10 through 17 years of age who are on a stable dose of a pediatric-approved statin monotherapy (atorvastatin, lovastatin, simvastatin or pravastatin), or who are treatment naive to lipid-lowering therapy.
The purpose of this study is to determine the efficacy of lapaquistat acetate, once daily (QD), on lowering cholesterol in subjects already taking atorvastatin.
The purpose of this study is to determine if patients with elevated cholesterol, but not taking any other lipid medication, could lower their cholesterol with administration of lapaquistat acetate, once daily (QD).
The purpose of this study is to evaluate the efficacy of Atorvastin vs Simvastatin in decreasing LDL-C in diabetic subjects with hypercholesterolemia at the end of the treatment phase.
Highly active antiretroviral therapy (HAART) has improved the long time survival of HIV infected individuals. However an increasing number of HIV-patients have developed metabolic and morphological alterations including peripheral lipoatrophy. The main hypothesis of the study is that switching from thymidine-analogue based HAART will reverse lipoatrophy. We plan to perform an observational study recruiting up to 100 HIV-infected patients receiving Trizivir (zidovudine/lamivudine/abacavir). The patients will be offered an NRTI or lopinavir/ritonavir instead of zidovudine or they can choose to continue with Trizivir. The main endpoint is changes in peripheral fat mass as determined by DEXA-scanning.
