Summary

Patients with end-stage renal disease (ESRD) who have elevated serum phosphate (P) levels have significantly higher mortality rates compared to those with normal P. In patients receiving conventional dialysis regimens, serum P may be lowered through dietary intervention and use of P binders, though these have potentially important side effects and may adversely impact quality of life. Whether lowering P, and / or targeting specific P levels improve survival and clinical outcomes is unknown. Despite this uncertainty, over 90% of patients with ESRD receive P lowering therapy and guidelines for the care of patients with ESRD are increasingly calling for more aggressive phosphate lowering. This intensive P lowering results in extra medications (and their associated side-effects), and higher health care costs. We are uncertain whether the intensification of P control results in measurable benefits to patients with ESRD. The overall goal of this pilot trial is to evaluate the feasibility of conducting a randomized controlled trial of intensive vs liberalized phosphate control among hemodialysis recipients.

Conditions

  • End-stage Renal Disease

Interventions

DRUG

Calcium carbonate ( Intensive phosphate control)

Individuals randomized to this arm will be exposed to a treatment strategy that targets a P of \< 1.50 mmol/L, reflecting the recommendations of current guidelines. Titration of the calcium carbonate dose will be the core of this approach and this will be complemented by usual recommendations regarding dietary P restriction. Dietitians will be available to provide counseling with regards to any aspect of the end-stage renal disease diet, as per usual dialysis unit practice

DRUG

Calcium carbonate (Liberalized phosphate control)

Individuals in this arm will be exposed to a treatment strategy that allows P to rise above 2.00 mmol/L. This will be accomplished through structured reduction of P binders already in use (as per the algorithm detailed below). "Rescue" P binding will be instituted if P rises above 2.50 mmol/L. Dietitians will be available to provide counseling regarding any aspect of the end-stage renal disease diet, as per usual dialysis unit practice, but will not provide counseling on dietary P restriction unless the P rises above 2.50 mmol/L.
