BACKGROUND: Classically, vitamin D has been implicated in bone health by promoting calcium absorption in the gut and maintenance of serum calcium and phosphate concentrations, as well as by its action on bone growth and reorganization through the action of osteoblasts and osteoclasts cells. However, in the last 2 decades, novel actions of vitamin D have been discovered. The present report summarizes both classic and novel actions of vitamin D. SUMMARY: 1,25(OH)2 vitamin D, the active metabolite of vitamin D, also known as calcitriol, regulates not only calcium and phosphate homeostasis but also cell proliferation and differentiation, and has a key a role to play in the responses of the immune and nervous systems...

Polycystic ovary syndrome (PCOS) is a pathophysiological disorder affecting reproductive and metabolic indices. PCOS is commonly associated with a high prevalence of insulin resistance and obesity; this association carries an increased risk of developing metabolic syndrome, type 2 diabetes mellitus (T2DM), and cardiovascular disease. Guidelines recommend lifestyle modification, metformin, hormonal contraceptives (HCs), and bariatric surgery as the main treatment options in obese patients with PCOS. Studies are being conducted to test the efficacy of existing treatment options as well as to discover new therapies...

Background: Several human studies reported that the combined use of renin-angiotensin system blockers (RASBs) and vitamin D receptor activators (VDRAs) resulted in decreased urinary protein excretion. However, it is unknown whether this combination therapy influences the incidence of cardiovascular (CV) events in dialysis patients. Methods: The study was a multicenter nonrandomized prospective cohort analysis including 1,518 patients. Patients were classified into 4 groups based on medications prescribed before dialysis initiation: those who did not receive RASBs or oral VDRAs (N group), those receiving only RASBs, those receiving only VDRAs, and those receiving a combination of RASBs and VDRAs (RD group)...

Albumin-corrected serum calcium (cSCa) decline at late stages of chronic kidney disease and rise after dialysis initiation. While hypercalcemia is associated with higher mortality in end-stage renal disease (ESRD), there are scarce data on the impact of pre-ESRD cSCa on post-ESRD mortality. Therefore, we used a large national cohort of 21,826 US veterans with incident ESRD who transitioned to dialysis in all US Department of Veterans Affairs healthcare facilities over 2009-2014 to examine the associations with all-cause and cause-specific post-ESRD mortality of (1) cSCa concentrations averaged over the last six months and (2) its rate of decline during the last 12 months before dialysis initiation...

Studies have shown a relationship between maternal periodontal diseases (PDs) and premature delivery. PDs are commonly encountered oral diseases which cause progressive damage to the periodontal ligament and alveolar bones, leading to loss of teeth and oral disabilities. PDs also adversely affect general health by worsening cardiovascular and metabolic diseases. Moreover, maternal PDs are thought to be related to increasing the frequency of preterm-birth with low birth weight (PBLBW) new-borns. Prematurity and immaturity are the leading causes of prenatal and infant mortality and is a major public health problem around the world...

2017 highlights benefits of prevention. Better control of cardiovascular risk reduces the incidence of dementia and monthly high-dose vitamin D the incidence of respiratory infections in nursing home. Pre-operative geriatric assessment lowers by 20% the rate of delirium after hip-fracture surgery and complications in vascular surgery. Deleterious effects are also reported. High-dose vitamin D triples the rate of falls in supplemented residents and doesn't improve gait speed in sedentary men. Widely used in cardiovascular prevention, antithrombotic therapy is associated with an astonishing risk of subdural bleeding that further increases with the number of drugs combined together...

Vitamin D (VD) and its analogues play critical roles in metabolic and cardiovascular diseases. Recent studies have demonstrated that VD exerts a protective role in cardiovascular diseases. However, the beneficial effect of VD on pressure overload-induced cardiac remodeling and dysfunction and its underlying mechanisms are not fully elucidated. In this study, cardiac dysfunction and hypertrophic remodeling in mice were induced by pressure overload. Cardiac function was evaluated by echocardiography, and myocardial histology was detected by H&E and Masson's trichrome staining...

Frailty is significantly associated with bone loss in the general population. However, it is unclear whether this association also exists in patients undergoing hemodialysis who have chronic kidney disease-mineral and bone disorder (CKD-MBD). This study aimed to assess the association between frailty and bone loss in patients undergoing hemodialysis. This cross-sectional study included 214 (90 women, 124 men) Japanese outpatients undergoing maintenance hemodialysis three times per week, with a mean age of 67...

Vitamin D deficiency, cardiovascular disease and abnormal bone mineral metabolism are common in chronic kidney disease (CKD). Abnormal bone mineral metabolism has been linked to vascular calcification in CKD. Sclerostin has emerged as an important messenger in cross talk between bone-vascular axis. We analyzed sclerostin in subjects who participated in the randomized, double blind, placebo controlled trial investigating the effect of cholecalciferol supplementation on vascular function in non-diabetic CKD stage G3-4 and vitamin D ≤20ng/ml [CTRI/2013/05/003648]...

Low 25-hydroxyvitamin D (25(OH)D) and elevated C-reactive protein (CRP) concentrations are independently associated with adverse health outcomes, including cardiovascular disease (CVD). Although an inverse association between these factors has been described, the underlying mechanisms remain unknown. We postulate that environment-gene interactions, through which 25(OH)D interacts with single nucleotide polymorphisms (SNPs) within the CRP gene, modulate CRP; that certain CRP genotypes predispose individuals to a co-phenotype of low 25(OH)D and elevated CRP concentrations; and that this co-phenotype is associated with higher CVD risk...

Vitamin D functions as a vitamin as well as a hormone. Its major skeletal actions are complemented by varied extra-skeletal functions. During the past decade, association between Vitamin D and its role in various non-skeletal morbidities have been recognized. It plays a role in decreasing the risk of many chronic illnesses like allergies, asthma, autoimmune diseases, diabetes, cancers, infections and cardiovascular disease. We report the case of a middle aged female with chronic quadriparesis and new onset anemia associated with Vitamin D deficiency...
