Excerpt
Cinacalcet is an activator of calcium-sensing receptors used for the treatment of secondary hyperparathyroidism among the dialysis population. By suppressing parathyroid hormone (PTH) levels and bone resorption, cinacalcet also lowers serum phosphorus levels among hemodialysis patients [
1]. On the other hand, among patients with chronic kidney disease stages 3–4, serum phosphorus levels increase after administration of cinacalcet due to suppression of phosphaturic effects of PTH and fibroblast growth factor (FGF)-23 [
2,
3]. We hypothesized that the effect of cinacalcet on phosphorus levels would be dependent on residual kidney function among patients on peritoneal dialysis (PD). …
