BACKGROUND A number of US observational studies reported an increased mortality risk with higher intact parathyroid hormone (iPTH), calcium and/or phosphate. The existence of such a link in a European haemodialysis population was explored as part of the Analysing Data, Recognising Excellence and Optimising Outcomes (ARO) Chronic Kidney Disease (CKD)(More)
The hormone fibroblast growth factor 23 (FGF23) is involved in mineral homeostasis but may also have a role in vascular calcification and bone mineralization. In a cohort of 142 patients with CKD stages 2–5D, plasma FGF23 was independently associated with aortic calcification but not with pulse wave velocity or bone mineral density. FGF23 is involved in(More)
BACKGROUND Atherosclerosis and vascular calcifications are common causes of morbidity and mortality in maintenance haemodialysis patients. In addition to the well-known traditional risk factors, uraemia-specific factors appear to enhance dramatically the progression of the pathological processes involved. The aim of the present study was to evaluate the(More)
BACKGROUND AND OBJECTIVES The dramatically high rates of mortality and cardiovascular morbidity observed among dialysis patients highlights the importance of identifying and implementing strategies to lower cardiovascular risk in this population. Results from clinical trials undertaken thus far, including trials on lipid reduction, normalization of(More)
Reduced serum levels of the calcification inhibitor fetuin-A associate with increased cardiovascular mortality in dialysis patients. Fetuin-A-deficient mice display calcification of various tissues but notably not of the vasculature. This absence of vascular calcification may result from the protection of an intact endothelium, which becomes severely(More)
The cells of the parathyroid gland secrete parathyroid hormone (PTH), which plays a pivotal role in maintaining circulating levels of ionized calcium (Ca2þ) within a narrow physiological range. The main actions of PTH include (i) releasing calcium and phosphorus from bone, (ii) decreasing renal calcium excretion, (iii) increasing urinary phosphorus(More)
The beta-2 microglobulin type of amyloidosis was identified in articular and para-articular tissues of 14 patients with non-amyloid nephropathies undergoing long-term hemodialysis. Ten patients had carpal tunnel syndrome, 13 had juxta-articular radiolucent cysts (complicated by spontaneous fractures of the femoral neck in three), and six had destructive(More)
Spinal radiologic lesions suggestive of destructive spondylarthropathy were found in 10 patients on long-term hemodialysis. These lesions were characterized by severe narrowing of the intervertebral disc, associated with erosions and geodes of the adjacent vertebral plates without osteophytosis. In 9 of the 10 patients the lesions were located in the(More)
The partial correction of anemia with recombinant human erythropoietin (rHuEpo) is frequently associated with an increase in arterial pressure and could oppose the beneficial effect of anemia correction on myocardial function. In order to analyze the influence of rHuEpo therapy on the vessels and the heart, we performed systemic and regional hemodynamics(More)
