    The Role of Secondary Calciprotein Particles in the Mineralisation Paradox of Chronic Kidney Disease.
    Calcif Tissue Int 2017 Aug 31. Epub 2017 Aug 31.
    Department of Nephrology, Royal Melbourne Hospital, Parkville, VIC, Australia.
    Mineralisation paradox is prevalent in chronic kidney disease and ageing where increased vascular calcification is accompanied by reduced bone mineralisation and osteopenia. Secondary calciprotein particles (CPP2), colloidal nanoparticles containing hydroxyapatite crystal stabilised by a protein shell, have been implicated in vascular calcification in chronic kidney disease. Here, we describe the effect of CPP2 on osteoblasts and vascular smooth muscle cells (VSMC) mineralisation in an in vitro model system. Read More

    Hyperphosphatemia induces senescence in human endothelial cells by increasing endothelin-1 production.
    Aging Cell 2017 Aug 31. Epub 2017 Aug 31.
    Instituto Reina Sofía de Investigación Nefrológica, IRSIN, Madrid, Spain.
    Hyperphosphatemia is related to some pathologies, affecting vascular cell behavior. This work analyzes whether high concentration of extracellular phosphate induces endothelial senescence through up-regulation of endothelin-1 (ET-1), exploring the mechanisms involved. The phosphate donor β-glycerophosphate (BGP) in human endothelial cells increased ET-1 production, endothelin-converting enzyme-1 (ECE-1) protein, and mRNA expression, which depend on the AP-1 activation through ROS production.

    Biology of Fibroblast Growth Factor 23: From Physiology to Pathology.
    Cold Spring Harb Perspect Med 2017 Aug 4. Epub 2017 Aug 4.
    Division of Bone and Mineral Research OMII, Harvard School of Dental Medicine, Boston, Massachusetts 02115.
    Fibroblast growth factor (FGF)23 is a phosphaturic hormone produced by osteocytes and osteoblasts that binds to FGF receptors in the presence of the transmembrane protein αKlotho. FGF23 mainly targets the renal proximal tubule to inhibit calcitriol production and the expression of the sodium/phosphate cotransporters NaPi2a and NaPi2c, thus inhibiting renal phosphate reabsorption. FGF23 also acts on the parathyroid glands to inhibit parathyroid hormone synthesis and secretion. Read More

    [Endocrine control of serum phosphate: from the discoveries of phosphatonins to novel therapies].
    Ann Endocrinol (Paris) 2016 Oct;77 Suppl 1:S36-S42
    AP-HP Department of Odontology, Bretonneau Hospital, and Reference Center for Rare Diseases of Calcium and Phosphorus Metabolism, and EA 2496, Laboratory Orofacial Pathologies, Imaging and Biotherapies, School of Dentistry University Paris Descartes Sorbonne, 12 Rue de l'École de Médecine, 75006 Paris, France.
    Phosphate is absorbed through the gut, stored in the bone and reabsorbed through the proximal renal tubule. More importantly, PTH and FGF23 have been identified as the main phosphaturic factors that control the expression of the phosphate co-transporters NaPi-IIa et IIc. By allowing the adjustment of the urinary phosphate reabsorption, these two phosphatonins play a major role in bone and tooth mineralization and growth. Read More

    Tumor lysis syndrome (TLS) is a potentially fatal condition defined both by laboratory and clinical criteria. It is caused by the catabolism of tumor cells which leads to considerable release and elevated levels of phosphate, potassium and uric acid in the bloodstream. These electrolyte derangements predispose patients to renal tubule uric acid precipitation, acute kidney injury, arrhythmias, neuromuscular irritability and even seizures. Read More

    Real-world effectiveness of sucroferric oxyhydroxide in patients on chronic hemodialysis: A retrospective analysis of pharmacy data
.
    Clin Nephrol 2017 Aug;88(8):59-67
    Aims: Hyperphosphatemia has been associated with an increased risk of mortality in patients with end-stage renal disease. We sought to assess the real-world effectiveness of sucroferric oxyhydroxide (SO), an iron-based phosphate binder (PB), in control of serum phosphorus levels, and to determine the associated pill burden in hemodialysis patients.

    Materials And Methods: Adult, in-center hemodialysis patients first prescribed SO through a renal pharmacy service as part of routine clinical care between April 1, 2014 and March 31, 2015 were included in the analysis. Read More

    A Review of Phosphate Binders in Chronic Kidney Disease: Incremental Progress or Just Higher Costs?

    As kidney disease progresses, phosphorus retention also increases, and phosphate binders are used to treat hyperphosphatemia. Clinicians prescribe phosphate binders thinking that reducing total body burden of phosphorus may decrease risks of mineral and bone disorder, fractures, cardiovascular disease, progression of kidney disease, and mortality. Recent meta-analyses suggest that sevelamer use results in lower mortality than use of calcium-containing phosphate binders. Read More

    Serum Phosphorus and Risk of Cardiovascular Disease, All-Cause Mortality, or Graft Failure in Kidney Transplant Recipients: An Ancillary Study of the FAVORIT Trial Cohort.
    Am J Kidney Dis 2017 Sep 2;70(3):377-385. Epub 2017 Jun 2.
    Division of Hypertension and Kidney Diseases, Department of Medicine, Rhode Island Hospital, Providence, RI. Electronic address:
    Background: Mild hyperphosphatemia is a putative risk factor for cardiovascular disease [CVD], loss of kidney function, and mortality. Very limited data are available from sizable multicenter kidney transplant recipient (KTR) cohorts assessing the potential relationships between serum phosphorus levels and the development of CVD outcomes, transplant failure, or all-cause mortality.

    Study Design: Cohort study. Read More

    Chronic kidney disease is known to be associated with phosphate retention. The mechanisms are complex and the early increase in serum phosphate levels in chronic kidney disease is not strictly related to the dietary phosphate load or to the degree of phosphate retention. It also implicates the activity of intestinal sodium-phosphate cotransporters, the degree of bone turnover and the retention and/or phosphate release from the skeleton, and the feedback mechanisms regulating the phosphaturia.

Electronic address:
    Chronic kidney disease causes hyperphosphatemia, which is associated with increased cardiovascular risk and mortality. In patients with end-stage renal disease, haemodialysis allows the control of hyperphosphatemia. During a 4-h haemodialysis session, between 600 and 700mg of phosphate are extracted from the plasma, whereas the latter contains only 90mg of inorganic phosphate. Read More
