BACKGROUND: Cardiovascular disease (CVD) begins early in children with chronic kidney disease (CKD), and its progression is determined by the presence of single or multiple cardiovascular risk factors (CVRFs). OBJECTIVE: To determine the prevalence of CVRFs in children with CKD and their association with mortality in children on chronic dialysis. METHODS: This comparative cross-sectional study recruited children aged 5 - 18 years with all stages of CKD...

BACKGROUND: Vascular calcification is common among patients with chronic kidney disease (CKD), and it is associated with all-cause and cardiovascular disease mortality. Deoxycholic acid, a metabolite of circulating bile acids, is elevated in CKD and induces vascular mineralization and osteogenic differentiation in animal models. STUDY DESIGN: Cohort analysis of clinical trial participants. SETTING & PARTICIPANTS: 112 patients with moderate to severe CKD (estimated glomerular filtration rate, 20-45mL/min/1...

BACKGROUND: Chronic kidney disease-associated mineral bone disorder (CKD-MBD) is common in pediatric kidney disease patients and a risk factor for future cardiovascular disease (CVD). Fibroblast growth factor-23 (FGF23) and Klotho are novel key players in CKD-MBD, and has been suggested to be involved in the development of CVD. METHODS: This prospective cohort study included 74 pediatric patients; 31 with CKD (age range 0.8-18.8 years, glomerular filtration rate (GFR) range 9-68 mL/min/1...

Abnormalities of bone turnover are commonly observed in patients with chronic kidney disease (CKD), and the low-turnover bone disease is considered to be associated with low serum parathyroid hormone (PTH) levels and skeletal resistance to PTH. Indoxyl sulfate (IS) is a representative uremic toxin that accumulates in the blood of patients with CKD. Recently, we have reported that IS exacerbates low bone turnover induced by parathyroidectomy (PTX) in adult rats, and suggested that IS directly induces low bone turnover through the inhibition of bone formation by mechanisms unrelated to skeletal resistance to PTH...

BACKGROUND: Bone is known to be impaired in chronic kidney disease and dialysis patients. Recent studies have shown that body composition (fat mass and lean mass) may impact bone health. Some of these effects may be related to mediators that are secreted by adipose tissue. METHODS: The aim of this study was to evaluate the association between body composition (dual x-ray absorptiometry [DEXA]) and adipokines (leptin, adiponectin), with bone density and microarchitecture assessed with high-resolution peripheral quantitative computed tomography (HR-pQCT) in chronic peritoneal dialysis (PD) patients in a single-center prospective study...

Persons with human immunodeficiency virus (HIV) infection often develop complications related directly to the infection, as well as to treatment. Aging, lifestyle factors, and comorbidities increase the risk of developing chronic conditions such as diabetes mellitus and chronic kidney disease. HIV-associated neurologic complications encompass a wide spectrum of pathophysiology and symptomatology. Cardiovascular and pulmonary conditions are common among persons with HIV infection. Although some specific antiretroviral medications have been linked to disease development, traditional risk factors (e...

We aim to evaluate the disturbances in mineral metabolism, abnormalities in bone mineral density (BMD), and extraskeletal calcification in newly detected, untreated predialysis stage 4 and 5 chronic kidney disease (CKD) patients at a tertiary care hospital in North India. This is cross-sectional observational study. A total of 95 (68 males, 27 females) newly detected patients underwent clinical evaluation, biochemical assessment [serum calcium, phosphorus, alkaline phosphatase (ALP), albumin, creatinine, intact parathyroid hormone (iPTH), 25- hydroxyvitamin D (25(OH)D)], BMD measurement (at spine, hip, and forearm) by dual-energy X-ray absorptiometry (DXA), lateral abdominal radiograph [for abdominal aortic calcification (AAC)], skeletal survey (to look for any abnormality including fractures), and echocardiography [for any cardiac valvular calcification (CVC)]...

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in patients with end-stage renal disease. Chronic kidney disease (CKD)-associated cardiovascular mortality is more prevalent in those with diastolic heart failure and is an early predictor, while increased left ventricular mass (LVM) is a strong independent risk factor. Hypovitaminosis D is extensively being studied as a nontraditional risk factor for CVD. The aim of the present study is to look at the association of Vitamin D and other parameters of mineral bone disorder (MBD) with diastolic dysfunction and LVM in nondiabetic young adult patients with CKD...

Prevalence of chronic kidney disease (CKD) is increasing worldwide principally among the elderly population many of whom will eventually need renal replacement therapy. The relationship between frailty and CKD in the elderly population has been recognized. However, studies concentrating on frailty in pre-dialysis patients are limited. CKD predisposes to frailty through many potential mechanisms; anemia, bone mineral disease, oxidative stress, and malnutrition which in turn lead to progression of CKD culminating in a vicious cycle...

Impaired bone quality is associated with fragility bone fractures independently of bone mineral density. Lifestyle disease-induced osteoporosis, such as diabetes or chronic kidney disease, and glucocorticoid-induced osteoporosis are listed as the diseases affecting bone quality. TBS(trabecular bone score)developed recently will be able to evaluate the trabecular microarchitecture quickly and easily. Various clinical studies evaluated bone quality by TBS has performed. I give an outline about the diseases affecting bone quality...

BACKGROUND: The cardiorenal syndrome (CRS) is a major health problem in our aging population. The term was introduced to cover disorders of the kidneys and heart, whereby dysfunction of one organ may induce dysfunction of the other. As the natural history of the CRS is mostly slow, hence difficult to explore in clinical trials, adequate animal models combining cardiovascular and renal disease are required. Therefore, we developed and characterized a usable model for CRS type 4, i.e. chronic kidney disease (CKD) causing cardiac dysfunction...

AIM: Chronic kidney disease related-mineral bone disorder (CKD-MBD) has been poorly studied in pre-dialysis Indian CKD population. There are limited data on the pattern of these disturbances in diabetic CKD patients. Therefore, a study was conducted to find out the profile of mineral bone disorders in T2DM patients with pre-dialysis CKD. METHODS: In this cross-sectional design, diabetic patients with newly-diagnosed stage 4 and 5 CKD were evaluated. Serum levels of calcium, phosphorus, intact parathyroid hormone (iPTH), 25 hydroxy vitamin D and total alkaline phosphatase (ALP) were measured in all patients...

Vitamin D is recognized to play an essential role in health and disease. In kidney disease, vitamin D analogs have gained recognition for their involvement and potential therapeutic importance. Nephrologists are aware of the use of oral native vitamin D supplementation, however, uncertainty still exists with regard to the use of this treatment option in chronic kidney disease as well as clinical settings related to chronic kidney disease, where vitamin D supplementation may be an appropriate therapeutic choice...

Calciprotein particles, nanoscale aggregates of insoluble mineral and binding proteins, have emerged as potential mediators of phosphate toxicity in patients with Chronic Kidney Disease. Although existing immunochemical methods for their detection have provided compelling data, these approaches are indirect, lack specificity and are subject to a number of other technical and theoretical shortcomings. Here we have developed a rapid homogeneous fluorescent probe-based flow cytometric method for the detection and quantitation of individual mineral-containing nanoparticles in human and animal serum...

Heart failure (HF) is a leading cause of morbidity and mortality in patients with chronic kidney disease (CKD), and the population of CKD patients with concurrent HF continues to grow. The accurate diagnosis of HF is challenging in patients with CKD in part due to a lack of validated imaging and biomarkers specifically in this population. The pathophysiology between the heart and the kidneys is complex and bidirectional. Patients with CKD have greater prevalence of traditional HF risk factors as well as unique kidney-specific risk factors including malnutrition, acid-base alterations, uraemic toxins, bone mineral changes, anemia and myocardial stunning...

BACKGROUND: High aldosterone level may contribute to pathogenesis of hypertension, vessels damage and cardiovascular system deterioration in chronic kidney disease patients. Besides its classical action via mineralocorticoid receptor, aldosterone is also involved in cell growth, inflammation, oxidative stress, endothelial dysfunction and exerts fibroproliferative effects. The aim of the study was to assess whether aldosterone antagonist treatment may influence serum level of inflammatory, fibrosis, thrombosis and mineral-bone metabolism markers in peritoneal dialysis (PD) patients and blood pressure, aortic stiffness, echocardiographic indices after 12 months of treatment...

The effects of PA21, a novel iron-based and non-calcium-based phosphate binder, on hyperphosphatemia and its accompanying bone abnormality in chronic kidney disease-mineral and bone disorder (CKD-MBD) were evaluated. Rats with adenine-induced chronic renal failure (CRF) were prepared by feeding them an adenine-containing diet for four weeks. They were also freely fed a diet that contained PA21 (0.5, 1.5, and 5%), sevelamer hydrochloride (0.6 and 2%) or lanthanum carbonate hydrate (0.6 and 2%) for four weeks...

OBJECTIVE: Epidemiologic studies have suggested a link between chronic systemic inflammation and chronic kidney disease-mineral and bone disorder (CKD-MBD). Additionally, declining renal function is associated with worsening physical and cognitive function, which may potentially be explained by systemic inflammation, CKD-MBD, or both. We hypothesized that inhibiting inflammation with an interleukin-1 (IL-1) trap would improve markers of CKD-MBD as well as physical/cognitive function in patients with moderate-to-severe CKD...

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...
