Parathyroid hormone-related peptide and primary hyperparathyroidism.
The parathyroid hormone-related peptide (PTHrP) has been shown to be the major pathogenic factor to humoral hypercalcemia of malignancy (HHM). The presence of PTHrP in many normal tissues and in normal or abnormal parathyroids has been described in literature and its role has been investigated. PTHrP release from parathyroid cells into the extracellular space has been demonstrated to depend on ...
متن کاملRapid intraoperative determination of intact parathyroid hormone during surgery for primary hyperparathyroidism. Experience at our center.
INTRODUCTION Primary hyperparathyroidism (PHPT) is due to a single adenoma in 85%-95% of cases, and is often cured after adenoma removal. Intraoperative rapid determination of intact parathyroid hormone (PTHio) may be a tool for monitoring the effectiveness of PHPT surgery. The main objective of our study was to evaluate PTHio determination and to establish whether its successful implementation...
متن کاملHypercalcemia in a patient with primary hyperparathyroidism and acromegaly: distinct roles of growth hormone and parathyroid hormone in the development of hypercalcemia.
We herein report a case of primary hyperparathyroidism associated with acromegaly. Although serum parathyroid hormone (PTH) levels increased after the resection of a pituitary adenoma, levels of serum 1a, 25-dihydroxyvitamin D [1, 25(OH)2D] decreased but remained above the normal upper limit. After resection of a parathyroid adenoma, serum PTH, 1, 25(OH)2D, calcium (Ca), and phosphate were all ...
متن کاملSubsternal oxyphil parathyroid adenoma producing PTHrP with hypercalcemia and normal PTH level
BACKGROUND Parathyroid adenoma is the most common cause of primary hyperparathyroidism. Preoperative serum calcium and intact-parathyroid hormone levels are the most useful diagnostic parameters that allow differentiating primary hyperparathyroidism from non-parathyroid-dependent hypercalcemia. Parathyroidectomy is the definitive treatment for primary hyperparathyroidism. Approximately 5% of pa...
