title: Cinacalcet versus Parathyroidectomy in the Treatment of Secondary Hyperparathyroidism Post Renal Transplantation.
abstract: BACKGROUND
  Persistent hyperparathyroidism (HPT) with hypercalcemia is prevalent after transplant and is considered a risk factor for progressive bone loss and fractures and vascular calcification, as well as the development of tubulointerstitial calcifications of renal allografts and graft dysfunction. The subtotal parathyroidectomy is the standard treatment, although currently it has been replaced by the calcimimetic cinacalcet.
  
  
  OBJECTIVE
  The hypothesis of this study is that subtotal parathyroidectomy is superior to cinacalcet for treatment of persistent secondary parathyroidectomy post renal transplant, with minimal morbidity and significantly it reduces the cost of treatment after transplantation.
  
  
  METHODS
  We report our long-term clinical experience with either cinacalcet or parathyroidectomy in 59 kidney transplant recipients with hyperparathyroidism. Group one included medical treatment with cinacalcet and had 45 patients while parathyroidectomy patients (group 2) were 16 patients with two of them excluded because of surgical failure.
  
  
  RESULTS
  No difference was found between groups for any parameter. A greater short-term change of calcium and phosphorus homeostasis obtained by surgery than by cinacalcet, and in long term change, no significant difference between the two groups.
  
  
  CONCLUSIONS
  The main findings of this study are that correction of severe hyperparathyroidism was similar in both surgical and cinacalcet groups with the absence of a difference of long-term serum iPTH 1-84 levels between the two groups.
