BACKGROUND: Hypoparathyroidism is a relatively rare endocrine disorder defined as inadequate parathyroid hormone (PTH) secretion leading to a clinical syndrome characterized by hyperphosphatemia and hypocalcemia. This condition has high morbidity; patients present with a heterogeneous range of emotional, mental, and physical symptoms. We present our experience with PTH transplantation, using parathyroid glands surgically removed in the setting of secondary hyperparathyroidism, with a description of the clinical course, immunosuppressive management, and surgical technique.
METHODS: Between 2017 and 2021, 3 patients underwent parathyroid allotransplantation at the University of Illinois at Chicago. The 2 outcomes of interest were (1) symptomatic relief and improvement in calcium levels and (2) time to graft failure, defined as the presence of undetectable PTH levels.
RESULTS: All 3 patients experienced dramatic improvement in their debilitating symptoms, even though 2 patients required repeated PTH transplantation procedures. One patient had a remarkable course with symptom resolution, normalization of PTH levels, and a great reduction in calcium supplementation.
CONCLUSION: The use of hyperplastic glands from patients with secondary hyperparathyroidism undergoing 4-gland parathyroidectomy with autotransplantation represents an important source. However, a uniform definition of graft viability and prospective studies with long follow-ups are needed to address how much parathyroid tissue is optimally transplanted and the need for immunosuppression. Most patients affected by hypoparathyroidism are successfully managed by medical treatment; however, some do not respond to therapy and present debilitating symptoms related to hypocalcemia. This subgroup may benefit from parathyroid allotransplantation. Our 3 patients had remarkable improvement in their symptoms with the adoption of hyperplastic glands. Two out of 3 patients required multiple procedures to sustain symptom control.
