Filter by:The investigators hypothesize that the chronic kidney disease patients who suffer from vitamin D deficiency will be benefit from given Vitamin D2 because coronary artery calcification and hyperparathyroidism will be improved.
The purpose of this study is to determine whether cholecalciferol supplementation in patients with chronic heart failure and low vitamin D levels improves: 1. performance at six minutes walking test 2. echocardiographic parameters 3. neurohormonal imbalance
Vitamin D3 is produced in the skin following exposure to UVB light from the sun or artificial sources, and occurs naturally in a small range of foods.More recently, several reports underlined the impact of vitamin D on the prevalence and consequences of inadequate vitamin D intake and the research supporting its benefits for alleviating chronic musculoskeletal pain and fatigue syndromes in outpatients. Experts have recommended that vitamin D inadequacy should be addressed in all patients with bone or joint pain, myalgia, fibromyalgia, or chronic fatigue syndrome. It appears that soothing the daily musculoskeletal pain by supplementation of vitamin D may be a simple, well tolerated, and cost-effective modality. Aim of study: To study the potential therapeutic effects of vitamin D supplementation on patients with persistent musculo-skeletal pain. Clinicalparameters, visual analog score,short form McGill Pain Questionnaire,patient global perceived effect, quality of life assessed by SF-36 Questionnaire and laboratory parameters, the levels of 25 OH-Vitamin D, CRP, IL-6, IL-8, TNF and prostaglandin E will be assessed.
The purpose of this research is to study whether vitamin D supplement can improve clinical outcome (PASI score) in psoriasis vulgaris with vitamin D insufficiency and deficiency.
Hypocalcemia is one of the most frequent complications of total thyroidectomy, a procedure used for benign as well as malignant conditions of the thyroid gland. Postoperative hypocalcemia is usually caused by hypoparathyroidism. Vitamin D is implicated in calcium metabolism as it increases intestinal calcium transport and regulates parathormone production. Aim of the present study is to evaluate preoperative vitamin D levels as a prognostic factor for postoperative hypocalcemia and hypoparathyroidism.
The aim of this 6 months study is to evaluate the metabolic effects of 400.000-600.000 IU of vitamin D supplementation in subjects with type 2 diabetes and hypovitaminosis D. The main hypothesis is that subjects with low levels of 25-OH-vitamin D will benefit from supplementation with cholecalciferol in sufficient doses to optimize serum levels.
The purpose of the study is to examine the vitamin D state of elder patients in therapeutic departments and to compere the treatment during the hospitalization with the out-patient treatment.
The purpose of this study is to determine the effect of normalization of vitamin D levels on bone density, immune and adipocyte function in HIV1-seropositive patients.
