Plasma endocan levels are elevated in a large number of diseases, and may reflect endothelial cell dysfunction. There are currently no data on endocan in patients with chronic kidney disease (CKD). Therefore, we measured plasma endocan in 251 patients with CKD (stage 1-5) and 60 control individuals. Plasma endocan concentrations correlated with estimated(More)
BACKGROUND The chronic kidney disease (CKD)-mineral and bone disorder (MBD) syndrome is an important contributor to the CKD-associated cardiovascular disease and high mortality rates. Sclerostin, a protein synthesized in osteocytes, is a potent downregulator of bone metabolism and a novel candidate for the bone-vascular axis in CKD patients. We tested(More)
BACKGROUND/AIMS The role of chronic kidney disease-mineral bone disorder (CKD-MBD) reversibility in the amelioration of vascular function and in the reduction of the risk for cardiovascular events after renal transplantation is still unknown. METHODS We investigated the longitudinal relationship between the main biomarkers of CKD-MBD and the evolution of(More)
BACKGROUND Magnesium is an essential ion for all living cells because over 300 enzymes require the presence of magnesium for their catalytic action. To date, no group has evaluated magnesium as a cardiovascular risk factor in chronic kidney disease (CKD) subjects, in which closely interrelated factors and potential confounders such as endothelial(More)
Previous studies showed that renal dysfunction was associated with both a reduction in serum high-density lipoprotein (HDL) cholesterol concentration and increased circulating monocyte count. We aimed to investigate the effect of circulating monocyte to serum HDL cholesterol ratio (M/H ratio) on fatal and composite cardiovascular events, in an observational(More)
BACKGROUND/AIMS Ramipril attenuates renal Fibroblast growth factor-23 (FGF-23) expression, ameliorates proteinuria and normalizes serum phosphate in the diabetic Zucker rat with progressive renal disease suggesting that the renoprotective effect by this drug may be in part due to a FGF-23-lowering effect of angiotensin-converting enzyme (ACE) inhibition.

BACKGROUND Red cell distribution width (RDW) is a measure of erythrocyte size variability and has been shown as an independent predictor of mortality. The aim of this article was to evaluate the association of RDW with endothelial dysfunction in patients with chronic kidney disease (CKD). METHODS Patients with 1 to 5 stages of CKD were included in the(More)
BACKGROUND Soluble TWEAK (sTWEAK) and asymmetric dimethyl arginine (ADMA) concentrations have been associated with endothelial function in patients with chronic kidney disease (CKD). We tested the hypothesis that the improvement in endothelial function observed after renal transplantation is directly linked to the normalization of both sTWEAK and ADMA. (More)
Cardiovascular disease (CVD) risk is substantially increased in subjects with chronic kidney disease (CKD). The Triglycerides (TG) to High-Density Lipoprotein Cholesterol (HDL-C) ratio is an indirect measure of insulin resistance and an independent predictor of cardiovascular risk. No study to date has been performed to evaluate whether the TG/HDL-C ratio(More)
BACKGROUND AND OBJECTIVES The role of reversibility of nontraditional risk factors, like inflammation and CKD-mineral bone disorder, in the reduction of cardiovascular risk after renal transplantation is still scarcely defined. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS The longitudinal relationship between C-reactive protein, CKD-mineral bone(More)
