| Outcome Measures: |
Primary: Fecal Phosphorus and Body Phosphorus Balance, Dose response relationship between lanthanum carbonate(Fosrenol) intake and fecal phosphorus excretion and body phosphorus balance. Specifically, the phosphorus content of feces, urine, expended dialysate, diet and any vomitus or rejected food will be measured., Two years | Secondary: Fecal Calcium and Nitrogen and Body Calcium and Nitrogen Balance, Fecal calcium and nitrogen and calcium and nitrogen balance in chronic peritoneal dialysis patients eating lanthanum carbonate (Fosrenol) intake. Effect of ingestion of Fosrenol on serum phosphorus and hormonal regulators of phosphorus metabolism as serum, parathyroid hormone (PTH), fibroblast growth factor-23, 25-hydroxycholecalciferol (25(OH)D3), 1,25-dihydroxycholecalciferol (1,25(OH)2D3) and fetuin-A., Two years|Protein-nitrogen balance, Lanthanum carbonate (Fosrenol) and increased intestinal phosphate binding on protein-nitrogen balance., Two years|Gastrointestinal symptoms, Gastrointestinal symptoms, particularly for anorexia, nausea vomiting, abdominal pain, distention, flatulence, constipation, diarrhea., Two years
