BACKGROUND Sevelamer hydrochloride was recently proposed as a phosphate binder to prevent hypercalcaemia in place of calcium alkaline salts in dialysis patients. So far, it has been evaluated only in patients receiving calcitriol, without comparison with CaCO(3) alone, although the latter was found to be as effective as the combination of calcitriol and(More)
We propose a new method for measuring aluminium in bone tissue, using argon plasma emission spectrophotometry. The detection limit in the bone nitric digestion liquid was 0.015 mumol/l (corresponding to 0.0075 mumol/g, i.e. 0.2 microgram/g for a tissue sample with 1.0 g wet weight). Within-run CVs were 4.66% and 1.43% for tissues containing 0.15 and 0.64(More)
In order to compare hemofiltration (HF) and hemodialysis (HD) in connection with the risk of aluminum overload and renal osteodystrophy, double bone biopsies after double tetracycline labeling and a desferrioxamine test were performed in 12 patients on HF and 15 patients on HD. The aluminum concentration was low (less than 0.6 mumol/l) both in the dialysate(More)
BACKGROUND Experimentally, leptin has a positive effect on bone mass when infused intravenously, but a negative one after intracerebroventricular administration. Renal failure increases its serum level above the concentration beyond which its transport to the brain may be saturated. Thus, we tested, in a chronic haemodialysis population, the hypothesis of a(More)
Contradictions exist in the literature regarding the effect of gastric secretion inhibition on phosphate absorption. In healthy controls, omeprazole would decrease the hyperphosphatemia or the hyperphosphaturia induced by an acute phosphate load, suggesting an inhibition of phosphate absorption. In chronic hemodialysis patients, gastric hypersecretion is(More)
Aldosterone suppression and subsequent hyperkalemia are well described reversible side effects of prolonged treatment with heparin. This study was designed to examine whether the discontinuous use of heparin three times a week to prevent thrombosis formation during hemodialysis sessions could also induce hypoaldosteronism and might contribute to increased(More)
During the last 4 years, the Permcath Quinton double-lumen silicone catheter was inserted into the internal jugular vein of 57 uraemic patients with difficulty for creating conventional vascular access for haemodialysis. In 4 patients, with definitive contraindication of conventional vascular access, this catheter still permits haemodialysis after a(More)
BACKGROUND Recent reports suggest that calcitriol might not be the sole active metabolite of vitamin D and that plasma concentrations of 25-(OH)vitamin D (25OHD) are often abnormally low in hemodialysis patients. We have therefore evaluated plasma 25OHD as a risk factor for parathyroid hormone (PTH) hypersecretion and radiological bone disease. We carried(More)
A previous short-term study of 10 weeks in 8 patients had shown us that with half the dose of elemental calcium, calcium acetate (CaAc) could control predialysis plasma phosphate (PPO4) as well as calcium carbonate (CaCO3) but that the incidence of hypercalcemia was not decreased. To better appreciate the value of CaAc in comparison to CaCO3, CaAc was given(More)
