Vitamin D Deficiency

Autor: Julia Fedotova

Número de Páginas: 284

Vitamin D is the topic for many discussions in the scientific community. Nowadays, a different interpretation of this secosteroid hormone is needed.

Vitamin D in 2020

Autor: Marie Courbebaisse , Etienne Cavalier

Número de Páginas: 166

Many things have been said and written on the skeletal and non-skeletal effects of vitamin D, but the largest recent interventional studies are generally negative. How should we thus position ourselves in 2020? Should we say “stop” or “not yet”? Indeed, the aging of the population, as well as new challenges and discoveries, is still triggering interest in this old molecule. In this Special Edition of Nutrients, we invited top experts to give their opinion on this important debate. We also encouraged scientists to submit their latest research on nutritional requirements in the general population and in high-risk groups, as well as treatment strategies, epidemiology, analytical updates and new devices for vitamin D measurement and the effect of vitamin D on bone and extra-skeletal health. As readers will see, this Special Issue reinforces the high prevalence of vitamin deficiency and insufficiency in the general population and supports the safety of this low-cost molecule, revealing new perspectives regarding the extra-skeletal effects of vitamin D.

Número de Páginas: 456

The Nutrition and Health series of books has as an overriding mission to provide health professionals with texts that are considered essential because each includes: a synthesis of the state of the science; timely, in-depth reviews by the leading researchers in their respective fields; extensive, up-to-date fully annotated reference lists; a detailed index; relevant tables and figures; identification of paradigm shifts and the consequences; of information between chapters, but targeted, inter-chapter refer virtually no overlap rals, suggestions of areas for future research; and balanced, data-driven answers to patient questions that are based on the totality of evidence rather than the findings of any single study. The series volumes are not the outcome of a symposium. Rather, each editor has the potential to examine a chosen area with a broad perspective, both in subject matter as well as in the choice of chapter authors. The international perspective, especially with regard to public health initiatives, is emphasized where appropriate. The editors, whose training is both research and practice oriented, have the opportunity to develop a primary objective for their book, define...

Número de Páginas: 169

The vitamin D is widely advertised as a solution for a large spectrum of diseases and health issues. Growing number of pharmaceuticals and supplements containing vitamin D, increasing availability of them in pharmacies, stores, online distribution and, sometimes, an intrusive commercial publicity campaigns have raised great interest, and have triggered reasonable controversies and fears. The self-administration of high doses of vitamin D has also appeared major concern in society. There is an increasing number of dilemmas regarding side effects including nephrocalcinosis, urinary stone disease, drug interactions and other adversity. On the other hand, it is recognized that vitamin D deficiency is a global health problem with potential negative consequences on health, welfare and morbidity during growth and adulthood, and therefore influencing health care services worldwide.

Vitamin D: From Pathophysiology to Clinical Impact, volume II

Autor: Luigi Di Filippo , Francesca Gorini , Cristina Vassalle

Número de Páginas: 253

Building on the success of our previous volume ''Vitamin D: From Pathophysiology to Clinical Impact'', we are pleased to launch Volume II of this Research Topic. Besides the well-known positive effects on skeletal homeostasis and bone metabolism, the growing evidence highlights the importance of vitamin D also in other many extra-skeletal conditions. In both adult and pediatric populations, conditions from inflammation and infectious diseases, obesity, and diabetes, to neurological disorders, gastrointestinal conditions, neurological disorders, cardiovascular health, and malignancies can be exerted through a number of mechanisms between vitamin D and its widely expressed receptor. This fact contributes to the increasing attention towards 25(OH)D measurement in laboratory medicine in both healthy and non-healthy general populations. Moreover, available dosing recommendations for vitamin D supplementation may considerably vary in the literature depending on the clinical setting and specific cohort evaluated. Indeed, currently, there are no specific guidelines and no clear consensus on goals for optimal vitamin D status and supplementation in most extra-skeletal conditions.

Genome-wide view on the physiology of vitamin D

Autor: Carsten Carlberg

Número de Páginas: 195

The main physiological actions of the biologically most active metabolite of vitamin D, 1a,25-dihydroxyvitamin D3(1a,25(OH)2D3), are calcium and phosphorus uptake and transport and thereby controlling bone formation. Other emergent areas of 1a,25(OH)2D3 action are in the control of immune functions, cellular growth and differentiation. This fits both with the widespread expression of the VDR and the above described consequences of vitamin D deficiency. Transcriptome-wide analysis indicated that per cell type between 200 and 600 genes are primary targets of vitamin D. Since most of these genes respond to vitamin D in a cell-specific fashion, the total number of vitamin D targets in the human genome is far higher than 1,000. This is supported by the genome-wide view on VDR binding sites in human lymphocytes, monocytes, colon and hepatic cells. All genomic actions of 1a,25(OH)2D3 are mediated by the transcription factor vitamin D receptor (VDR) that has been the subject of intense study since the 1980’s. Thus, vitamin D signaling primarily implies the molecular actions of the VDR. In this research topic, we present in 15 chapters different perspectives on the action of vitamin D...

Vitamin D Binding Protein, Total and Free Vitamin D Levels in Different Physiological and Pathophysiological Conditions

Autor: Daniel David Bikle , Zhongjian Xie , Xiangbing Wang

Número de Páginas: 86

There is a high prevalence of vitamin D deficiency worldwide, but how to define vitamin D deficiency is controversial. Currently, the plasma concentration of total 25-hydroxyvitamin D [25(OH)D] is considered an indicator of vitamin D status. The free hormone hypothesis states that protein-bound hormones are inactive while unbound hormones are free to influence biological activity. The majority of circulating 25(OH)D and 1,25(OH)2D is tightly bound to vitamin D binding protein (DBP), 10 -15% is bound to albumin, and less than 1% of circulating vitamin D exists in an unbound form. While DBP is relatively stable in most healthy populations, recent studies have shown that there are gene polymorphisms associated with race and ethnicity that could alter DBP levels and binding affinity. Furthermore, in some clinical situations total 25(OH)D levels are altered, and knowing whether DBP is also altered may have implications for diagnosis and treatment. In this Research Topic, we provide a collection of comprehensive research on vitamin D and DBP metabolism among different ethnic population and patients with different diseases.

Vitamin D

Autor: Veronica D. Stolzt

Número de Páginas: 200

Vitamin D is a fat-soluble steroid hormone precursor that contributes to the maintenance of normal levels of calcium and phosphorus in the bloodstream. Strictly speaking, it is not a vitamin since human skin can manufacture it, but it is referred to as one for historical reasons. It is often known as calciferol. The major biologic function of vitamin D is to maintain normal blood levels of calcium and phophorus. Vitamin D aids in the absorption of calcium, helping to form and maintain strong bones. It promotes bone mineralisation in concert with a number of other vitamins, minerals and hormones. Without vitamin D, bones can become thin, brittle, soft or misshapen. Vitamin D prevents rickets in children and osteomalacia in adults -- skeletal diseases that result in defects that weaken bones. This book gathers international research on the leading-edge of the scientific front.

Vitamin D in Chronic Kidney Disease

Autor: Pablo A. Ureña Torres , Mario Cozzolino , Marc G. Vervloet

Número de Páginas: 583

Vitamin D deficiency, circulating levels lower than 15 ng/ml, is an epidemic disease worldwide with more than a billion people suffering of it in the beginning of the 21-century. Besides its impact on mineral and bone metabolism, these low vitamin D levels are also associated with a diversity of non-skeletal complications, among them cardiovascular disease, diabetes mellitus, multiple sclerosis, cancer, tuberculosis, and immune system dysfunction. Chronic Kidney Disease is also a very common disease, affecting more than 10% of the world population, ranging from stage 1 to stage 5 before dialysis. Approximately 1% of the population in industrialized countries is affected by end-stage renal disease (ESRD), needing a renal replacement therapy either hemodialysis or peritoneal dialysis, and ultimately by renal transplantation. Those CKD patients are more susceptible to exhibit reduced vitamin D stocks. Consequently, more than eighty percent of CKD patients have either insufficient or deficient vitamin D levels for multiple reasons.

Vitamin D and Rickets

Autor: Z. Hochberg

Número de Páginas: 299

Centuries ago, during the industrial revolution, rickets, also called 'the English disease', spread rapidly among city-dwelling poor children and became endemic due to vitamin D deficiency and insufficient access to sunlight. Nowadays it appears to be endemic again as the increase of vitamin D deficiency is paralleling the primacy of breast-feeding in Western societies. Breastfeeding, nutritional status and dark skin are the main risk factors for rickets or 'rachitis' as is the correct medical term. Rickets is a childhood disorder and the basis for understanding the disease is rooted in the concept of mineral metabolism and its control mechanisms in the growing fetus, infant and child. As it is now understood that rickets is not only caused by vitamin D deficiency, it has to be kept in mind that vitamin D and calcium deficiency is prevalent in developing countries as well as in affluent societies, where children and their mothers are not exposed to as much sunlight as they need. The rapid growth in molecular biology has been exemplified in the application of subcellular technologies to study vitamin D in human and animal models. In this volume the latest research on vitamin D and...
