Fetuin-A is an important inhibitor of extraosseous calcification, but some of the studies that used ELISAs did not identify a significant relationship between serum fetuin-A levels and vascular calcification in patients with chronic kidney disease (CKD). Here, we used centrifugation to separate a fetuin-mineral complex (FMC) composed of fetuin-A,(More)
PURPOSE Low 25-hydroxyvitamin D (25D), increased levels of fibroblast growth factor 23 (FGF23), parathyroid hormone (PTH), and alkaline phosphatase (ALP) were reported to be risk factors for mortality in chronic kidney disease (CKD). However, the independent associations of these factors with cardiovascular disease (CVD), the leading cause of death among(More)
Although dual blockade of the renin-angiotensin-aldosterone system (RAAS) with the combination of an angiotensin-converting enzyme inhibitor (ACE-I) and angiotensin II receptor blocker (ARB) is generally well-established as a treatment for nephropathy, this treatment is not fully effective in some patients. Based on the recent evidence implicating(More)
BACKGROUND AND OBJECTIVES Hyperphosphatemia, vitamin D deficiency, hyperparathyroidism, and high serum fibroblast growth factor 23 (FGF23) levels, when studied separately, were found to predict the progression of CKD. However, studies with simultaneous measurement of mineral bone disorder (MBD)-related factors were scarce. This study aimed to identify(More)
AIMS We studied whether adding the spherical adsorptive carbon AST-120 to conventional treatments is effective in inhibiting progression of chronic kidney disease (CKD) at the stage of moderate decrease in renal function. METHODS 43 CKD patients with moderately impaired renal function indicated by glomerular filtration rate (GFR) of 20-70 ml/min as(More)
BACKGROUND AND OBJECTIVES Nocturnal hypoxemia is highly prevalent among patients with CKD. Nocturnal hypoxemia contributes to systemic inflammation, oxidative stress, endothelial cell dysfunction, and activation of the renin-angiotensin system, which are common pathologic mechanisms of CKD progression. This study investigated whether nocturnal hypoxemia is(More)
Although diabetes mellitus (DM) disturbs bone metabolism, little is known concerning its effects on laboratory abnormalities in chronic kidney disease-mineral and bone disorders (CKD-MBD). We extracted data for 602 patients from the Osaka Vitamin D Study in patients with CKD (OVIDS-CKD), an observational study enrolling predialysis outpatients. No enrolled(More)
CONTEXT Vitamin D, often deficient in kidney transplant (KTx) recipients, has potential immunomodulatory effects. OBJECTIVE This study aimed to evaluate whether vitamin D status affects the rate of decline in kidney allograft function. DESIGN, SETTING, AND PATIENTS The study included a prospective cohort of 264 ambulatory KTx recipients at a single(More)
BACKGROUND Recent studies have demonstrated that podocyte injury, which results in proteinuria, leads to tubulointerstitial fibrosis. Although some studies have revealed that vitamin D administration protects renal structure and function in mesangial cell proliferative and/or excessive matrix productive models, the effects of vitamin D on podocyte injury(More)
The role of 25-hydroxyvitamin D [25(OH)D] and fibroblast growth factor-23 (FGF-23) in chronic kidney disease-mineral and bone disorder (CKD-MBD) remains elusive in predialysis CKD patients. From the fact that FGF-23 suppresses bone mineralization in vitro and that 1alpha-hydroxylase is present in parathyroid cells and osteoblasts, they may be associated(More)
