Vitamin D deficiency is common and associated with mortality in chronic kidney disease (CKD) patients. Cardiovascular disease (CVD) is the commonest cause of mortality in CKD patients. In a randomized, double blind, placebo controlled trial, we have recently reported favorable effects of vitamin D supplementation on vascular & endothelial function and inflammatory biomarkers in vitamin D deficient patients with non-diabetic stage 3-4 CKD (J Am Soc Nephrol 28: 3100-3108, 2017). Subjects in the placebo group who had still not received vitamin D after completion of the trial received two oral doses 300000 IU of oral cholecalciferol at 8 weeks interval followed by flow mediated dilatation (FMD), pulse wave velocity (PWV), circulating endothelial and inflammatory markers (E-Selectin, vWF, hsCRP and IL-6), 1,25 (OH)2D, iPTH and iFGF-23 assessment at 16 weeks...

BACKGROUND: The relationship between serum corrected calcium (CCa) level and vessel calcification at dialysis initiation and survival has seldom been evaluated. Therefore, we evaluated the efficacy of CCa levels and the calcification score at the initiation of dialysis for predicting all-cause and cardiovascular (CV) mortality in patients with end-stage renal disease (ESRD). METHODS: The study group included 407 patients with ESRD, who started hemodialysis between January 2009 and December 2016 at the Red Cross Ishinomaki Hospital...

Vascular calcification is a component of cardiovascular disease, which is leading cause of death in patients with chronic kidney disease (CKD). A functional assay (T50-test) measuring the propensity of human serum to calcify associates with mortality and cardiovascular events in CKD patients. Calcification propensity is known to increase with CKD stage. We investigated whether the T50 readout is directly dependent on excretory kidney function (eGFR) or rather explained by deranged parameters of bone and mineral metabolism in the course of CKD...

A number of histologic changes are associated with the medial arterial calcification that occurs in chronic kidney disease, leading to several different hypotheses concerning the underlying mechanism. Careful timing of these changes in relation to the onset of the calcification, as reported in this issue of the journal, can shed light on which changes are pathogenic as opposed to secondary in reaction to the calcification.

Vascular calcification is a serious complication of chronic kidney disease, but the current therapeutic strategy is insufficient for preventing its progression. Magnesium is a potent inhibitor of calcification and represents a promising therapeutic candidate. Diaz-Tocados and colleagues now demonstrate that magnesium supplementation prevents the progression of vascular calcification in a uremic rat model, independently of the phosphate-binding capacity. We should keep in mind, however, that too much magnesium could have adverse effects on bone metabolism...

BACKGROUND: Arterial stiffness is an independent predictor of all-cause and cardiovascular mortality in patients with chronic kidney disease (CKD). There are limited prospective data however on progression of arterial stiffness in CKD, including evaluating associations with bone mineral markers such as fibroblast growth factor 23 (FGF23) and soluble α-klotho (sKl). METHODS: In this prospective, single-center, observational study, arterial stiffness [measured by pulse wave velocity (PWV)] and hormones influencing mineral homeostasis, including serum FGF23 and sKl, were compared between non-dialysis CKD stages 4/5 and healthy controls at baseline and 12 months (12 m)...

Vascular calcification is common in patients with advanced kidney disease, and has been strongly linked to cardiovascular morbidity and mortality in the general population. Recent clinical and translational studies demonstrate that vascular calcification is also associated with cardiovascular morbidity in the setting of chronic kidney disease, and that once established, may persist even when kidney function is restored.

Although magnesium has been shown to prevent vascular calcification in vitro, controlled in vivo studies in uremic animal models are limited. To determine whether dietary magnesium supplementation protects against the development of vascular calcification, 5/6 nephrectomized Wistar rats were fed diets with different magnesium content increasing from 0.1 to 1.1%. In one study we analyzed bone specimens from rats fed 0.1%, 0.3%, and 0.6% magnesium diets, and in another study we evaluated the effect of intraperitoneal magnesium on vascular calcification in 5/6 nephrectomized rats...

AIM: Many studies have validated Agatston's coronary artery calcification score (CACS) for assessing vascular calcification (VC) in chronic kidney disease (CKD) patients. This study aimed to evaluate the CACS and common iliac artery calcification score (IACS) and to examine the variables related to each score. METHODS: The subjects were 145 non-dialysis CKD patients. The CACS and IACS were determined using the same thoracicoabdominal multi-detector computed tomography...

Vascular calcifications worse outcomes in the general population and in patients on dialysis. We investigated 146 patients on chronic hemodialysis and 63 healthy controls with normal renal function under 65 years of age. All subjects underwent B-mode ultrasonography of common and internal carotid artery, abdominal aorta, common and superficial femoral artery and posterior tibial artery to assess the presence of intimal and medial calcifications. Intimal and media calcifications were present at the level of the carotid vessel, the abdominal aorta, the common femoral artery, the superficial femoral artery and the posterior tibial artery, respectively in 45%, 50%, 45%, 50%, 42% of patients on dialysis and in 5%, 15%, 24%, 5%, 2% of controls (p <0,01)...

In recent years, the mechanisms and clinical significance of vascular calcification have been increasingly investigated. For over a century, however, pathologists have recognized that vascular calcification is a form of heterotopic ossification. In this review, we aim to describe the pathology and molecular processes of vascular ossification, to characterize its clinical significance and treatment options, and to elucidate areas that require further investigation. The molecular mechanisms of vascular ossification involve the activation of regulators including bone morphogenic proteins and chondrogenic transcription factors and the loss of mineralization inhibitors like fetuin-A and pyrophosphate...

Vascular calcification represents the deposition of calcium phosphate salts in the tunica media of the vascular wall. It occurs during aging but is accelerated and pronounced in patients with diabetes mellitus, chronic kidney disease (CKD) and established cardiovascular disease. Due to the loss of elasticity of the vessel wall, vascular calcification might result in left ventricular hypertrophy and compromise coronary perfusion. Accordingly, several studies showed that vascular calcification is associated with increased risk for cardiovascular morbidity and mortality...

Cardiovascular disease is the main cause of early death in the settings of chronic kidney disease (CKD), type 2 diabetes mellitus (T2DM), and ageing. Cardiovascular events can be caused by an imbalance between promoters and inhibitors of mineralization, which leads to vascular calcification. This process is akin to skeletal mineralization, which is carefully regulated and in which isozymes of alkaline phosphatase (ALP) have a crucial role. Four genes encode ALP isozymes in humans. Intestinal, placental and germ cell ALPs are tissue-specific, whereas the tissue-nonspecific isozyme of ALP (TNALP) is present in several tissues, including bone, liver and kidney...

Coronary arteries in patients with chronic kidney disease (CKD) have been shown to exhibit more extensive atherosclerosis and calcium. We aimed to assess characteristics of coronary plaque in hemodialysis (HD)-dependent patients using optical coherence tomography (OCT). This was a multicenter, retrospective study of 124 patients with stable angina who underwent OCT imaging. Sixty-two HD-dependent patients who underwent pre-intervention OCT for coronary artery disease were compared 1:1 with a cohort of patients without CKD, matched for age, diabetes mellitus, gender, and culprit vessel...

BACKGROUND: Coronary artery disease (CAD) is common in asymptomatic chronic dialysis patients and plays an important role in their poor survival. Early identification of these high-risk patients could improve treatment and reduce mortality. Abdominal aortic calcification (AAC) has previously been associated with CAD in autopsy studies. Since the AAC can be quantified easily using a lateral lumbar X-ray we hypothesized that the extent of AAC as assessed on a lateral lumbar X-ray might be predictive of the presence of significant CAD in dialysis patients...

Based on native CT scans of the pelvic region using a standardized calcification score, evaluation of iliac vascular calcification was performed between 2008 and 2012 prior to listing for renal transplantation in 205 patients with chronic kidney disease. Vascular calcification showed a decrease from proximal to distal. The difference between the degree of calcification in the common iliac artery and in the external iliac artery was significant (P<.001). Risk factors for total iliac vascular calcification were age, smoking, sex, underlying renal disease, and diabetes...

BACKGROUND: Vascular calcification has been recognized to be a major risk factor in chronic kidney disease (CKD) and downstream cardiovascular complications. Micro-RNAs (miRNAs) are small noncoding RNAs comprising 20-25 nucleotides that regulate gene expression by inhibiting or degrading the target mRNA, and constitute potential new biomarkers and future therapeutic strategies. SUMMARY: We tested the relevance of several cardiovascular-specific miRNAs as new biomarkers for CKD, cardiovascular disease, and cardiovascular complications...

BACKGROUND: Vascular calcification is significant because of the close association between the degree of vascular calcification and cardiovascular mortality in chronic kidney disease (CKD) patients. SUMMARY: There are 2 types of vascular calcification in CKD patients. One is endothelial vascular calcification, a common type of vascular calcification. Another is medial vascular calcification, a specific type that is common in CKD patients. The former is mainly associated with atherosclerosis due to hyperlipidemia, especially hypercholesterolemia...
