Objective To evaluate the effectiveness of total parathyroidectomy (PTX) with autotransplantation in the treatment of secondary hyperparathyroidism (HPT), and to assess recurrence rate of HPT in this peritoneal dialysis (PD) population.Design A retrospective study in a single home PD unit.Patients Between 1994 and 1998, 19 of 574 patients on PD underwent PTX for treatment of secondary HPT.Main Outcome Measures Clinical and biochemical improvement, recurrence of HPT, improvement in anemia post-PTX.Results Nineteen (3.3%) patients required PTX between 1994 and 1998. These 5 men and 14 women ranged in age from 22 to 66 years; they had been on maintenance PD pre-PTX for 47.5 ± 38.1 months, and were followed for 26.1 ± 15.5 months post-PTX. Sixteen patients had temporary hypocalcemia that was managed by oral (n= 10) or intravenous (n= 6) calcium supplements and calcitriol, while 3 patients had severe “hungry bone” syndrome postoperatively. One patient had recurrent laryngeal nerve palsy post-PTX. Bone pain disappeared in all 12 patients. Pruritus improved in 12/13 patients; fatigue improved in 15/16 patients. Comparison showed significant differences between hemoglobin and hematocrit values 1 month pre-PTX and 12 months post-PTX (p< 0.05). Parathyroid hormone (PTH) level in 15 (79%) patients returned to normal (≤€7.6 pmol/L) during the first month post-PTX. In 5/12 (42%) patients, PTH level was ≤ 7.6 pmol/L 2 years post-PTX, while in 2/12 (17%), PTH was > 22.8 pmol/L (three times normal) 2 years post-PTX, and 3/5 (60%) patients had a PTH > 22.8 pmol/L 3 years post-PTX.Conclusions Total PTX with autotransplantation is associated with a tendency for recurrence of HPT. Our findings suggest that total PTX with autotransplantation may be an ineffective procedure in controlling HPT over the long term. |
