Long-term outcome following total parathyroidectomy in patients with end-stage renal disease.
Long-term follow up (mean 3.8 years), following elective total parathyroidectomy in thirteen patients with end-stage renal disease is described. Nine patients are alive and all except two have measurable levels of intact parathyroid hormone (PTH). One patient is mildly hyperparathyroid with PTH levels of 143 pg/ml (normal 10-65 pg/ml). All patients did well as far as their bone and mineral metabolism were concerned and there were no fractures, bone pain or metastatic soft tissue calcification. Lumbar spine bone mineral density (BMD) increased above the baseline value and femoral neck bone density was significantly greater than a matched control group of non-parathyroidectomized dialysis patients (1.097 +/- 0.140 versus 0.811 +/- 0.148 g/cm2, Z-score 1.98 +/- 1.64 versus -0.79 +/- 1.07, p < 0.001). Two of the nine patients have been transplanted, both have good allograft function and show increases in BMD. We believe that these findings justify the complete removal of all parathyroid tissue for selected patients with chronic renal failure where medical therapy has failed and aluminium bone disease has been excluded. They also raise the possibility that PTH is necessary for bone loss to occur.
