Can calcimimetics inhibit parathyroid hyperplasia? Evidence from preclinical studies.
The cells of the parathyroid gland secrete parathyroid hormone (PTH), which plays a pivotal role in maintaining circulating levels of ionized calcium (Ca2þ) within a narrow physiological range. The main actions of PTH include (i) releasing calcium and phosphorus from bone, (ii) decreasing renal calcium excretion, (iii) increasing urinary phosphorus excretion and (iv) stimulating renal productio...
متن کاملRisk-factors for nodular hyperplasia of parathyroid glands in sHPT patients
INTRODUCTION Nodular hyperplasia of parathyroid glands (PG) is the most probable cause of medical treatment failure in secondary hyperparathyroidism (sHPT). This prospective cohort study is located at the interface of medical and surgical consideration of sHPT treatment options and identifies risk-factors for nodular hyperplasia of PG. MATERIAL AND METHODS One-hundred-eight resected PG of 27 ...
متن کاملControl of parathyroid cell growth by calcimimetics.
Parathyroid cell hyperplasia is commonly observed in patients with chronic renal insufficiency and largely accounts for refractory secondary hyperparathyroidism. Calcimimetics are newly synthesized compounds that activate a calcium receptor on the parathyroid cell and can suppress parathyroid hormone secretion. The calcimimetic compound AMG 073 has been examined in clinical trials, and the data...
متن کاملParathyroid hormone without parathyroid glands.
In mammals, PTH is a component in a complex signaling system involving three structurally related ligands and two G protein-coupled receptors, which share significant amino acid sequence homology (Fig. 1). PTH is a peptide hormone comprising 84 amino acids that is made by the parathyroid glands (and to a much smaller extend by the thymus) and acts through the PTH/PTH-related peptide (PTHrP) rec...
متن کاملCorrelation of subtraction parathyroid scintigraphy with weight, pathohistologic finding and oxyphil cell content of parathyroid glands in parathyroid hyperplasia.
BACKGROUND/AIM Parathyroid hyperplasia (PHP) is defined as an absolute increase in the mass of parenchymal cells of the parathyroid gland. PHP is classified as primary, secondary and tertiary. The enlargement of parathyroid glands (PG) is usually asymmetric, resulting in a "dominant" gland. In order to confirm the diagnosis, at least two glands should be examined histologically. Subtotal parath...
