Oxidative stress has a role in uremic neuropathy and may be involved in RLS of ESRD patients.Vitamin E &Vitamin C are potential antioxidant supplement that are used in hemodialysis patients safely.
In recent years, vitamin D has been shown not only to be important for bone and calcium metabolism but also for homeostasis of critical tissues involved in vascular disease in patients with diabetes. Epidemiological studies indicated the high prevalence of vitamin D deficiency among Type 2 DM patients and suggest an increased risk of cardiovascular disease and hypertension with low vitamin D levels. The objective of this proposal is to evaluate the effects of vitamin D replacem...
In the United States, cardiovascular disease causes over one-third of all deaths and vitamin D deficiency is an epidemic. An increasing body of data suggests that low vitamin D status adversely impacts the cardiovascular system. It is our fundamental hypothesis that vitamin D deficiency is a risk factor for cardiovascular disease by causing endothelial dysfunction. Moreover, we hypothesize that vitamin D supplementation will restore endothelial function, thereby reducing car...
This is a 9 months, randomized, single center, open-label, parallel-group study to compare the efficacy and safety parameters of vitamin D supplementation in vitamin D deficiency subjects in China.
The purpose of this study is to answer the following questions: Does vitamin D increase calcium absorption, bone mass and muscle mass and function in women past menopause who have mildly low vitamin D levels? Do these benefits require prescription-strength vitamin D, or is an over the counter vitamin D dose enough?
The purpose of this study is to determine if Vitamin D supplementation helps prevent recurrent cardiovascular events, such as heart attack or stroke, in patients who have already experienced at least one cardiovascular event. This study will investigate if the addition of 150,000 international units of cholecalciferol (vitamin D3) by mouth every 2 months to a subject's medication regimen will prevent further cardiovascular events.
To determine if supplements of vitamin C, vitamin E, beta-carotene, and B-vitamins (folic acid, vitamins B6 and B12) reduce risk of major cardiovascular events in high risk women with a prior history of atherosclerotic cardiovascular disease. The trial is a companion to the Women's Health Study (WHS), a primary prevention trial of vitamin E and aspirin in a low risk population of women.
Six-hundred subjects with vitamin D deficiency will be randomized to vitamin D 3000 IU per day versus placebo for 4 months, with effects on cardiovascular risk factors as main endpoint
Vitamin D is available in two forms, vitamin D2 and vitamin D3. It has previously been assumed that these two forms maintain blood vitamin D equally. However, this may not be the case. This study will evaluate whether D2 and D3 produce equal elevation of blood vitamin D. Additionally, it will evaluate whether once per month vitamin D dosing is as effective in maintaining blood vitamin D levels as daily dosing.
The purpose of this study is to examine whether vitamin B supplementation will reduce the progression of early atherosclerosis in individuals over 40 years old and without clinical evidence of cardiovascular disease (CVD).
Hypovitaminosis D is highly prevalent in the general population, particularly in obese individuals. Besides being associated with obesity, vitamin D deficiency seems to be involved in the pathogenesis of insulin resistance and low-grade chronic inflammation. In addition, it has been reported that individuals with low vitamin D levels are at increased risk for cardiovascular diseases. A healthy diet and weight loss are cornerstones in the prevention of cardiovascular diseases. V...
The life span of adults with end-stage renal disease is reduced, and cardiovascular disease (CVD) accounts for approximately half the deaths among those undergoing hemodialysis (HD). Vascular calcification is a key process in the development of atherosclerotic and arteriosclerotic CVD, and contributes significantly to the greater mortality rates and CVD events in HD patients. Recently, there has been growing interest in the vitamin K-dependent matrix Gla protein (MGP) and its r...
This study evaluates the relationship between vitamin-D status and severity of sarcoidosis, and the effects of vitamin-D repletion in vitamin-D insufficient patients with sarcoidosis. Half the patients with sarcoidosis who are vitamin-D insufficient will receive standard vitamin-D supplementation via standard regimen while the other half will receive a placebo. Sarcoidosis patients who are vitamin-D sufficient will also act as controls.
Randomised, placebo-controlled dose-response intervention study with vitamin D3 in pregnant women.
Study Goal #1: Determine the optimal oral dose of vitamin C to reduce surrogate markers of atherosclerosis (blockages in blood vessels) following the consumption of an atherogenic high fat lunch in type 2 diabetic individuals. Study Goal #2: After conducting the original study, we found that vitamin E was not effective in reducing the markers of oxidative stress, hypercoagulation, inflammation, and metabolic parameters in patients with type 2 diabetes. To date, data fro...
The trial plan to determine whether a daily capsule containing vitamin D(3) (2000 IU), calcium (600 mg), both, or a placebo for 6 months in UAE citizens with evidence of vitamin D deficiency will lead to a clinical benefit. The proposed study will also determine the threshold of vitamin D and calcium intake or levels considered optimal for UAE citizen's health
The purpose of this study is to determine if vitamin D supplementation changes the results of certain tests associated with inflammation in the body using an oral, synthetic form of vitamin D called paricalcitol.
The aim of this study is to evaluate cardiovascular events during long-term follow-up in Rheumatoid Arthritis. The primary outcome "any cardiovascular event" will be evaluated using systematic audits of patient records, and will be associated to low levels of vitamin D at baseline, to investigate the hypothesis that low levels of vitamin D can be part of a prediction model for cardiovascular disease in Rheumatoid Arthritis.
Previous studies have shown high proportions of vitamin D deficiency among elderly in Denmark. Vitamin D is important for muscular function. The investigators intend to examine if it is possible to improve cardiovascular function in patients with heart failure and vitamin D deficiency by supplementation with vitamin D.
This study will assess the effects of vitamin D3 supplementation (cholecalciferol; 2000 IU daily) on serum calcium levels, circulating vitamin D levels, and markers of kidney disease and cardiovascular risk among people with diabetes mellitus and early kidney disease. Eligibility criteria include type 2 diabetes and stage 1-2 chronic kidney disease, defined by a urine albumin-creatinine ratio 30-300 mg/g and an estimated glomerular filtration rate ≥ 60 mL/min. Participants wi...
A significant proportion of the United Kingdom population have inadequate levels of vitamin D in their blood. Vitamin D is a fat-soluble vitamin that is essential for the growth and maintenance of healthy bones through increasing dietary calcium absorption within the body. A low vitamin D status has also been associated with other diseases such as osteoporosis, cancer (especially colorectal cancer), cardiovascular disease and type 1 diabetes. Our skin is able to synthesise vita...
Both Coronary Artery Calcification (CAC)and its annual progression are a strong predictors of cardiovascular events. The development of arterial calcification results from imbalance between calcification promoting and inhibiting factors. An important inhibitor of calcification is Matrix Gla Protein (MGP): a protein present in the vascular wall where it is synthesized by Vascular Smooth Muscle Cells (VSMC). MGP requires Vitamin K-mediated carboxylation to function properly. Defi...
A randomized clinical trial to determine if vitamin D repletion in CKD (Chronic Kidney Disease) patients with low vitamin D levels will decrease proteinuria, a marker of kidney damage.
The investigators want to make sure that people get the right dose of Vitamin D treatment. They will therefore investigate how skin colour, body mass index, ethnicity, vitamin D binding protein and genetic variation affect the response to a standard course of vitamin D in young adults, as a prelude to further studies in younger children.
We hope to learn the clinical and functional signs of sub-clinical vitamin B12 deficiency and its response to supplementation in non-anemic, non-pregnant, and non-lactating women in Rural Mexico. Vitamin B12 is important in hematopoiesis, neuro-cognitive functions and genetic integrity. However vitamin B12 is only found in animal source foods therefore a large segment of the population in developing countries and those practicing vegetarianism are at risk of deficiency of the v...
