Vascular calcification has detrimental consequences on chronic kidney disease (CKD) patients, yet its pathogenesis is not fully understood. Fibroblast growth factor-23 (FGF-23) involved in the regulation of mineral metabolism which may turn affect vascular calcification. Data relationship between FGF-23 and peripheral calcification, using conventional radiographs, are conflicting, less known about relation to aortic We conducted this study investigate a standard haemodialysis setting.The...

Fibroblast growth factor-23 (FGF-23) has been linked to vascular calcification, ventricular hypertrophy and mortality in chronic kidney disease (CKD), although these links may not be direct independent. Similar grave outcomes are associated with inflammation oxidative stress CKD. Recently, accumulating evidence components of phosphate homeostasis stress. The interaction between the triad inflammation, FGF-23 cardiovascular is underinvestigated.We studied 65 patients stage 5 CKD on...

Insulin resistance (IR) is very common among chronic kidney disease (CKD) patients. Disturbance in mineral and bone metabolism (MBD) seems to play a role the pathogenesis of insulin resistance. Fibroblast growth factor-23 (FGF23) evolving as most important link between MBD many pathologic sequences CKD. The aim was evaluate IR pre-dialysis CKD patients looking for possible association A total 100 stage 3–5 were selected beside 20 normal control subjects. Homeostatic model assessment...

Systemic inflammation is a recognized feature in chronic kidney disease (CKD). The role of systemic the pathogenesis vascular calcification was recently settled. FGF23 accused as direct stimulus inflammation. This finding explains strong association to and increased mortality among CKD.

Serum 25-hydroxyvitamin D (25(OH)D) negatively correlates with serum phosphorus level of stage 3a-5 chronic kidney disease (CKD) patients. So far, no explanation has been provided for this negative association.To confirm association and determine if relationship is mediated through other known co-morbid factors.One hundred (57 male 43 female) pre-dialysis CKD patients were selected. Estimated glomerular filtration rate (eGFR), calcium (Ca), (P), 25(OH)D, parathyroid hormone (PTH), intact...

Background Patients with diabetic kidney disease (DKD) are at increased risk to develop post-contrast acute injury (AKI). Diabetic patients under dipeptidyl peptidase 4 inhibitors (DPP4Is) experience a lower propensity AKI. We speculated that linagliptin as single agent or in combination allopurinol may reduce the incidence of AKI stage 3–5 chronic (CKD) underlying DKD.Methods Out 951 DKD eligible for this study, 800 accepted sign informed consent. They were randomly allocated equal groups...

Many of the mineral metabolite abnormalities encountered in chronic kidney disease (CKD) patients were found also associated with acute injury (AKI). In last decade, sclerostin was to intimately affect bone metabolism CKD patients. Nothing is known about AKI. We looked for serum level AKI comparison normal control subjects and if there an impact on metabolic derangement, endothelial function or clinical outcome. This a cross sectional case observational study 219 cases (group I) beside age...

The non-calcium-based phosphate binder sevelamer hydrochloride was developed to provide chronic kidney disease patients with a polymer capable of managing hyperphosphatemia without an increase in the calcium load. These beneficial effects were postulated as mechanism decreased progression vascular calcification observed such compounds.
