WebMar 30, 2024 · The findings suggest that NPHPT is an early stage of PHPT, and further studies are needed to determine the role of FGF-23 and its usefulness in N PHPT. Introduction Normocalcemic primary hyperparathyroidism is a variant of primary hyperparathyroidism with consistently normal albumin-adjusted or free-ionized calcium … WebC-terminal peptides mainly oppose the activities of PTH (1-34) and are increased in renal failure (1-3). PTH expression is mainly restricted to the parathyroid gland, with minor amounts in the thymus (4). PTH secretion is enhanced by low Ca ++ concentrations and inhibited by FGF-23 (1, 5). In normal human plasma, PTH correlates negatively with ...
