The action you just performed triggered the security solution. In particular, deregulated calcium and vitamin D levels facilitate calcification through stimulating both VSMC osteogenic differentiation and mineralisation. Therefore, justification for the clinical use of supplementation in ameliorating calcification progression still needs to be validated. Furthermore, as the concepts around calcification regulation have evolved to become more complex, it is unlikely that the primary mechanism responsible for its pathogenesis and progression would involve such a passive and linear process.

By helping to draw calcium into the bones and teeth, vitamin K may help reduce the amount of calcium in soft tissues, like the arteries. Calcifediol, which is normally bound to the circulating vitamin D binding protein (DBP), can undergo a subsequent round of hydroxylation by another cytochrome P450 enzyme, 1-hydroxylase (CYP27B) in the kidneys to produce the active vitamin D metabolite, calcitriol (1,25-dihydroxyvitamin D3), which ultimately elicits the effects of vitamin D by binding and signalling through the vitamin D receptor (VDR) in target tissues. Introduction. Given the presence of bone elements, it is therefore important to recognise calcified vasculature as manifestations of bone-like tissue encapsulating osteoblast-like cells and haematopoietic elements, with calcium and phosphate actively accumulating as part of the bone matrix composition rather than stagnant mineral deposits. Notably, deregulation of vitamin D metabolism, dietary calcium intake and renal mineral handling are associated with imbalances in systemic calcium and phosphate levels and endothelial cell dysfunction, which can modulate both bone and soft tissue calcification. In one prospective study, serum calcifediol concentrations of less than 20 ng/mL in pre-hospitalised patients were associated with increased odds of 90-day mortality [117]. (3) recently concluded that after a follow-up of 6 years, patient coronary artery calcification (CAC) scores were independently associated with composite cardiovascular outcomes after correcting for novel and traditional cardiovascular risk factors [43]. More significant correlations between vitamin D deficiency and cardiovascular mortality have also been reported from older populations [116,118], and in female cohorts [119]. 2005 Jul-Aug;18(4):307-14. doi: 10.1111/j.1525-139X.2005.18407.x. Qunibi W.Y., Nolan C.A., Ayus J.C. Cardiovascular calcification in patients with end-stage renal disease: A century-old phenomenon. The mechanism for vitamin D deficiency in promoting inflammation-driven calcification may be explained by the impact of pro-inflammatory factors on the endothelium, which mediates endothelial stress and dysfunction that can then become the stimulus for calcification [105]. Current understanding of vitamin Ds involvement during VC is limited, and primarily relies on evidence provided from experimental studies. Clipboard, Search History, and several other advanced features are temporarily unavailable. In uremic rat models, medial calcification in the aorta and ectopic calcification within soft tissue have been detected despite low levels of serum calcium and calcitriol, and instead have been associated with extremely high levels of PTH and inorganic phosphate [95]. ), 2Centre for Kidney Research, Childrens Hospital at Westmead, Westmead, NSW 2145, Australia, 3Cellmid Limited, 2/55 Clarence St, Sydney, NSW 2000, Australia; ua.moc.dimllec@nostrebor. Furthermore, calcification outcomes were associated with higher levels of high-sensitivity C-reactive protein indicating systemic inflammation within the low level group, while those of the high level group were linked with deregulated calcium/phosphate metabolism. Recent findings: Tibial artery calcification was identified and quantified over 3 years in Deficient vitamin D levels, in the form of calcifediol, has been linked with increased cardiovascular and non-cardiovascular mortality in a number of large-scale clinical and epidemiological studies [76].

WebIn addition to its effects exerted on numerous tissues and organs that indirectly participate in the atherosclerosis, vitamin D is directly involved in this systemic inflammatory process.

Association between Serum 25-Hydroxyvitamin D and Abdominal Aortic Calcification: A Large Cross-Sectional Study. Calcium deposits in your arteries can lead to high blood pressure, kidney disease and more. In addition to precursor forms of vitamin D, such as D2 and D3, dosing of its active metabolite, calcitriol, also produces diffuse and widespread soft tissue calcification that has been demonstrated in a time-dependent manner in rats [88]. Previous vitamin D deficiency studies involving LDLR knockout mice found increased TNF- expression concomitant with the upregulation of osteogenic factors and aortic calcification in mice with inadequate vitamin D intake [96,97]. Summary: Despite the general consensus on diagnosing vitamin D-related diseases/disorders based on circulating levels, there is still controversy surrounding whether aberrant levels of vitamin D are equivalent to perturbed activity, given the nature of its metabolism and signalling.

Interestingly, the primary endothelial stress mechanism currently known for calcification, which concerns the stimulation of the EMT process and the expression of BMPs and MGPs, has yet to be linked to vitamin D deficiency. 2008 Dec;29(6):423-32. doi: 10.1016/j.mam.2008.04.002. Excess supplementation of calcefidiol however, leads to saturation of free calcifediol levels that exceeds DBP binding capacity, which then directly induces gene expression and functional changes in target cells [78]. Differential effects of vitamin D analogs on vascular calcification. Elevated FGF 23 and phosphorus are associated with coronary calcification in hemodialysis patients. Received 2018 Apr 14; Accepted 2018 May 17. There is substantial clinical and experimental evidence suggesting that osteoblast-like cells within calcified tissue can originate from pericytes in microvessels, pericyte-like vascular and endothelial cells in the intima, and vascular smooth muscle cells (VSMCs) in the media which undergo osteogenic/chondrogenic differentiation in response to osteogenic signals.

Recent evidence indicates that many non-atherosclerotic calcification cases may be a result of modulations in the levels and activities of calcification promoters and inhibitors. Following the recognition of additional extraosseous bone-like mineralised tissue within these vessels, VC was subsequently acknowledged as an active, pathobiological process with some features of bone morphogenesis, but also displaying distinct cellular and molecular processes.

While this may be the case in normal chemical solutions, in the vasculature, calcium and phosphate levels are tightly regulated under physiological conditions such that spontaneous accumulation is less likely to induce calcification [52]. National Library of Medicine Mol Aspects Med. Lack of synthesis of precursors in the skin primarily leads to inadequate production of calcifediol, which consequently results in reduced downstream effects. A rare and obliterative form of VC known as calcific uremic arteriolopathy, or calciphylaxis, occurs almost exclusively within end-stage renal disease (ESRD) patients, and is characterised by extensive skin necrosis, ulcer formation and visceral plaque accumulation [13,14,15]. Such VDR-mediated mineralisation is associated with increases in alkaline phosphatase activity and receptor activator of nuclear factor kappa-B ligand (RANKL)/osteoprotegerin (OPG) ratios, and decreases in PTH-related peptide expression levels [89,90].
