BACKGROUND: Metabolic syndrome (MetS) identifies subjects with increased risk of cardiovascular disease when they have a combination of insulin resistance, obesity, hypertension, hyperglycemia, low high-density lipoprotein cholesterol (HDL-C), and elevated triglycerides (TGs). Increasing evidence suggests that vitamin D deficiency could be associated with diabetes and MetS. The aim is to assess if 25-hydroxyvitamin D (25-OHD) is correlated with cardiovascular risk components of MetS. METHODS: A cross-sectional study involved 124 diabetic patients with MetS according to International Diabetes Federation definition...

Vitamin D deficiency (<20 ng/mL) and insufficiency (20-29 ng/mL) are common among patients with chronic kidney disease (CKD) or undergoing dialysis. In addition to nutritional and sunlight exposure deficits, factors that affect vitamin D deficiency include race, sex, age, obesity and impaired vitamin D synthesis and metabolism. Serum 1,25(OH)₂D levels also decrease progressively because of 25(OH)D deficiency, together with impaired availability of 25(OH)D by renal proximal tubular cells, high fibroblast growth factor (FGF)-23 and decreased functional renal tissue...

Vitamin D deficiency affects a large part of the population of elderly people, especially women, who live in moderate climate countries due to a reduced amount of vitamin D in the diet (small sea fish consumption) and reduced content of 7-dehydrocholesterol, which causes decreased skin synthesis. The lowest seasonal concentration of 25(OH)D3 is usually observed during winter and spring. Sun exposure influences 25(OH)D3 concentration more strongly in men than in women. Sociodemographic factors that increase the risk of vitamin D deficiency in the elderly include poor environmental conditions, low economic status, lower educational level, drug exposure (smoking), reduced physical activity, overall poor health and obesity, which causes reduced skin exposure to sunlight...

Michael J Berridge
Vitamin D deficiency has been linked to the onset of diabetes. This review summarizes the role of Vitamin D in maintaining the normal release of insulin by the pancreatic beta cells (β-cells). Diabetes is initiated by the onset of insulin resistance. The β-cells can overcome this resistance by releasing more insulin, thus preventing hyperglycaemia. However, as this hyperactivity increases, the β-cells experience excessive Ca(2+) and reactive oxygen species (ROS) signalling that results in cell death and the onset of diabetes...

Muscle weakness is a hallmark of severe vitamin D deficiency, but the effect of milder vitamin D deficiency or insufficiency on muscle mass and performance and risk of falling is uncertain. In this presentation, I review the evidence that vitamin D influences muscle mass and performance, balance, and risk of falling in older adults. Special consideration is given to the impact of both the starting 25-hydroxyvitamin D [25(OH)D] level and the dose administered on the clinical response to supplemental vitamin D in older men and women...

BACKGROUND: Vitamin D deficiency is discussed to be associated with lung health. While former studies focused on subjects suffering from pulmonary diseases, we aimed to investigate the association of 25-hydroxy vitamin D [25(OH)D] with lung function in the general population and examined whether mediating effects of inflammation, glycemic control or renal function exist. METHODS: 1404 participants from the Study of Health in Pomerania with pulmonary function testing assessed by expiratory volume in 1 s (FEV1), forced vital capacity (FVC), total lung capacity and Krogh index were used...

BACKGROUND: Bone marrow edema syndrome (BMOS) is a phenomenon primarily affecting the lower extremity. It is characterized by a sudden onset of pain and an ill-defined osseous hyperintense signal in magnetic resonance imaging. The main cause of BMOS is still largely unknown. Its pathophysiology is presumably multifactorial and it has recently been demonstrated that it usually involves an increase in bone turnover and alterations within the bone microenvironment. Vitamin D plays a pivotal role in maintaining a healthy and well-balanced bone microenvironment...

Background.: Vitamin D deficiency and excess of circulating fibroblast growth factor 23 (FGF23) contribute to cardiovascular mortality in patients with chronic kidney disease (CKD). FGF23 activates FGF receptor 4 and (FGFR4) calcineurin/nuclear factor of activated T cells (NFAT) signaling in cardiac myocytes, thereby causing left ventricular hypertrophy (LVH). Here, we determined if 1,25-dihydroxyvitamin D (calcitriol) inhibits FGF23-induced cardiac signaling and LVH. Methods...

Objective: To evaluate the impact of clinical decision support (CDS) tools on rates of vitamin D testing. Screening for vitamin D deficiency has increased in recent years, spurred by studies suggesting vitamin D's clinical benefits. Such screening, however, is often unsupported by evidence and can incur unnecessary costs. Materials and Methods: We evaluated how rates of vitamin D screening changed after we implemented 3 CDS tools in the electronic health record (EHR) of a large health plan: (1) a new vitamin D screening guideline, (2) an alert that requires clinician acknowledgement of current guidelines to continue ordering the test (a "hard stop"), and (3) a modification of laboratory ordering preference lists that eliminates shortcuts...

Chronic heart failure is a major cause of morbidity and mortality, but its prognosis remains poor. Vitamin D hormone has many extra-skeletal functions including a positive impact on the cardiovascular system, and has been proposed for mortality risk evaluation in heart failure patients. The aim of the present study was to evaluate vitamin D status in heart failure patients, measured by high performance liquid chromatography coupled with mass spectrometry and to correlate serum 25 hydroxy-vitamin D (25OHD) levels with functional (peak VO2%) and mortality (Metabolic Exercise Cardiac Kidney Index) heart failure parameters...

Secondary hyperparathyroidism(SHPT)is the result of a compensatory response of the calcium phosphate homeostatic mechanism. Vitamin D deficiency and chronic kidney disease, both representative pathophysiological causes of SHPT, have been related not only to skeletal disorders but also cardiovascular diseases, ADL and QOL. This relates the importance of SHPT as a pathological cause or marker of such states.

Emerging evidence from in vivo and in vitro studies have shown that vitamin D may play an important role in the development of diabetic retinopathy (DR), but individually published studies showed inconclusive results. The aim of this study was to quantitatively summarize the association between vitamin D and the risk of diabetic retinopathy. We conducted a systematic literature search of Pubmed, Medline, and EMBASE updated in September 2016 with the following keywords: "vitamin D" or "cholecalciferol" or "25-hydroxyvitamin D" or "25(OH)D" in combination with "diabetic retinopathy" or "DR"...

Introduction: Vitamin D deficiency is common worldwide with adverse effects on skeletal health. In recent years, there has been great interest in non-classical actions of vitamin D. Basic research has uncovered actions in a range of non-skeletal tissues, and observational studies have identified inverse relationships with risk of a number of disease states including sarcopenia, obesity, the metabolic syndrome, cardiovascular disease, cancer and autoimmune diseases. Sources of data: PubMed, Medline and Cochrane Systematic Reviews...

OBJECTIVE: Vitamin D deficiency is quite common among end-stage renal disease (ESRD) patients, and Vitamin D administration could reduce morbidity and mortality in these patients through different mechanisms. Cardiovascular diseases are the most common cause of mortality in these patients that are caused by vascular injuries. Intracellular adhesion molecule (ICAM) and vascular cell adhesion molecule (VCAM) are vascular inflammation indicators. The goal of this study is to find the effect of Vitamin D administration on ICAM-1 and VCAM-1 serum levels in ESRD patients on hemodialysis...
