Simultaneous kidney-parathyroid allotransplantation from a single donor after 20 years of tetany: a case report.
Persistent hypocalcemia after total parathyroidectomy and autotransplantation is rare and occasionally has been treated using allotransplantation of parathyroid tissue. We present the case of a 32-year-old woman with terminal renal failure who at age 5 years underwent a first renal transplantation from a brain-dead donor. The graft was lost as a result of acute rejection. Tertiary hypoparathyroidism developed, which was treated with total parathyroidectomy and implantation in the forearm of a standardized amount of parathyroid tissue. The graft failed, and hypoparathyroidism developed. Despite a second implantation of cryopreserved autologous tissue, severe hypocalcemia persisted with a tendency for tetany. Although the patient was highly dependent on high-dose vitamin D(3) (tacalcitol) and calcium supplements, regular paresthesias and tetany developed. At age 9 years, the patient underwent a second renal transplant from a living related donor (her mother). After 18 years, the graft was lost as a result of chronic cyclosporine toxicity and angiosclerosis. Four years later, the patient underwent combined kidney and parathyroid transplantation from a local brain-dead donor. Preservation of the parathyroid glands was in University of Wisconsin solution, with cold ischemia time of 14 hours. Directly after the renal transplantation, parathyroid transplantation was performed, with implantation in the forearm of the total amount of donor parathyroid tissue. Postoperatively, there was recovery of parathyroid function, and the patient was able to discontinue vitamin D and calcium supplements after more than 20 years.
