Tertiary hyperparathyroidism: a review.

Clin Ter 2021 May;172(3):241-246

Department of Surgical, Oncological and Oral Sciences, University of Palermo, Palermo, Italy.

Abstract: Tertiary hyperparathyroidism (HPT III) occurs when an excess of parathyroid hormone (PTH) is secreted by parathyroid glands, usually after longstanding secondary hyperparathyroidism. Some authorities reserve the term for secondary hyperparathyroidism that persists after successful renal transplantation. Long-standing chronic kidney disease (CKD) is associated with several metabolic disturbances that lead to increased secretion of PTH, including hyperphosphatemia, calcit-riol deficiency, and hypocalcaemia.
