Persistent hypophosphathemia recovered with cinacalcet in a late renal transplanted patient

Renal transplant recipients with secondary hyperparathyroidism often have hypophosphatemia that can persist for years. We report the case of a renal transplanted patient with normal allograft function showing persistent hypophosphoremia due to secondary hyperparathyroidism despite treatment with oral supplements of phosphorus and calcitriol. After initiation of treatment with cinacalcet, a normalization of serum phosphorus was rapidly achieved, and phosphorus supplementation was not necessary. Renal function remained stable. Dial.
