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 The subtotal parathyroidectomy is the standard treatment, although currently it has been replaced by the calcimimetic cinacalcet.Aim. 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.

In the hemodialysis population, the incidence of Staphylococcus aureus colonization has been documented to be as high as 80%; effective prophylaxis of vascular access infection and bacteremia is a worthwhile goal in the management of hemodialysis population. Surveillance of 50 hemodialysis patients for S. aureus-positive nasal cultures was performed by monthly nasal swabs over a 12-month period. All patients were performing dialysis using hemodialysis catheters thrice weekly. All positive cultures were treated with a prophylactic antibiotic regimen. Thirty-one patients (62%) had one or more positive cultures. The surveillance period was longer in the S. aureus nasal carriers (p < 0.01). The frequency of positive cultures correlated with the duration of surveillance (p < 0.05). The incidence of S. aureus bacteremia was greater in patients with three or more positive cultures (p < 0.05). This study suggests that continuous surveillance for S. aureus nasal colonization is essential to properly identify all hemodialysis patients using catheters at risk of developing S. aureus bacteremias.
