[The contribution of dialysis and laboratoristic methods for the control of phosphates].
Prevention and correction of hyperphosphatemia is the first main goal of CKD-MBD management. Therefore, special attention is required to prevent a positive phosphate balance. In addition to a careful use of phosphate binders and dietary, phosphate control is needed to optimize the control of phosphate balance. In well-nourished patients is necessary to provide an optimal dialysis removal schedule. A solution could be the increase of the number of dialysis sessions per week and to carry out longer dialysis session strategies. Nevertheless, many patients have a high phosphate (P) intake linked to the high dietary protein requirement of dialysis patients, hence the use of intestinal P binders is mandatory to reduce P net intestinal absorption. Unfortunately the phosphate molecule must be considered as a medium molecular toxin. Nowadays it remains difficult to remove with modern dialysis strategies and ones clearance is still dependent on dialysis time. The best solutions are: hemodiafiltration with high-volume reinfusion, daily dialysis, long dialysis and modern peritoneal dialysis. Today, this scheduled strategies are difficult because of logistic and cost problems. However the milestone will be an adequate nutrition surveillance, especially with nursing collaboration toward dialysis treatments. This strategy should start in outpatient pre-dialysis ambulatory.
