Outcome Measures: |
Primary: Measurement of the serum levels of C terminal segment of fibroblast growth factor 23 (FGF23) and evaluation of sevelamer carbonate effect on this levels in comparison with placebo, Indeed the sevelamer carbonate could lead to a diminution of FGF23 serum levels due to the diminution of intestinal absorption of dietary phosphate., 12 weeks after the beginning of treatment | Secondary: Evaluation of sevelamer carbonate effect on the serum levels of iPTH, 12 weeks after the beginning of treatment|Evaluation of sevelamer carbonate effect on the serum levels of calcitriol (1 25(OH)2D3), 12 weeks after the beginning of treatment|Evaluation of sevelamer carbonate effect on the serum levels of others mineral metabolism parameters (phosphore, calcium, intact FGF-23 , 25(OH)D3, bone specific alkaline phosphatases, osteocalcin, collagen crosslink, C reactive protein), 12 weeks after the beginning of treatment|Evaluation of sevelamer carbonate effect on the urinary levels of phosphate, 12 weeks after the beginning of treatment|Evaluation of sevelamer carbonate effect on the urinary levels of calcium, 12 weeks after the beginning of treatment|Evaluation of sevelamer carbonate effect on the urinary levels of creatinine, 12 weeks after the beginning of treatment|Evaluation of sevelamer carbonate effect on the urinary levels of urea, 12 weeks after the beginning of treatment|Evaluation of sevelamer carbonate effect on the serum and urinary levels of specific biomarkers (serum : fetuin A, para-cresyl sulfate, osteopontin), 12 weeks after the beginning of treatment
