Renal Papillary Necrosis Associated With Normocalcemic Primary Hyperparathyroidism. [PDF]
AACE Clin Case Rep, 2021 Renal papillary necrosis (RPN) occurring in primary hyperparathyroidism (PHPT) has not been reported. We present a 50-year-old woman who manifested RPN associated with hypercalciuria and normocalcemic PHPT.The diagnosis of RPN was based on imaging studies (ultrasound and computed tomography [CT] scan).

Vitamin D Hydroxylation-deficient Rickets Type 1A Misdiagnosed as Normocalcemic Primary Hyperparathyroidism. [PDF]
JCEM Case Rep, 2023 Vitamin D hydroxylation-deficient rickets type 1A is an autosomal recessive disorder caused by pathogenic variants in CYP27B1 gene, which encodes for 1α-hydroxylase, the enzyme responsible for the conversion of 25-OH vitamin D into its active form 1,25 ...

Normocalcemic primary hyperparathyroidism. [PDF]
J Clin Densitom, 2013 Primary hyperparathyroidism, a common endocrine disorder, is traditionally defined by hypercalcemia and elevated levels of parathyroid hormone (PTH). A newer presentation of primary hyperparathyroidism has been described over the past decade, in which PTH is elevated but serum calcium is consistently normal, in the absence of secondary causes of ...

Appropriate Cutoff for 25OHD Levels in the Diagnosis of Normocalcemic Primary Hyperparathyroidism (NPHPT): A Systematic Review [PDF]
J Endocr Soc, 2021 Introduction: The Fourth International Workshop in 2014 delineated guidelines for the diagnosis of NPHPT which include ruling out secondary causes of hyperparathyroidism, and recommended cutoffs for 25 vitamin D (25OHD) to be ≥20ng/mL.

PTH immunoassay interference: differential diagnosis with normocalcemic primary hyperparathyroidism? [PDF]
Arch Endocrinol MetabSUMMARY The main diagnostic dilemma in normocalcemic hyperparathyroidism is differentiating this condition from secondary hyperparathyroidism and other causes of elevated parathyroid hormone (PTH) levels in eucalcemic patients, including potential assay ...

Normocalcemic primary hyperparathyroidism. [PDF]
Arq Bras Endocrinol Metabol, 2010 Primary hyperparathyroidism is a common disorder of mineral metabolism characterized by incompletely regulated, excessive secretion of parathyroid hormone from one or more of the parathyroid glands. The historical view of this disease describes two distinct entities marked by two eras.

Normocalcemic Primary Hyperparathyroidism [PDF]
, 2012 Normocalcemic primary hyperparathyroidism is a new entity which possibly represents a fruste form of the classic clinically symptomatic disease and which has generated a considerable scientific interest in the last decade. Its official recognition is just as recent as in 2008, when an international conference took place for clarifying its nature and ...

Clinical, Biochemical, and Radiological Profile of Normocalcemic Primary Hyperparathyroidism [PDF]
The Journal of Clinical Endocrinology & Metabolism, 2020 Abstract Context The clinical and radiological aspects of normocalcemic hyperparathyroidism (NHPT) are confounded by the differing methods used to rule out secondary hyperparathyroidism and by the small sample size.

Incidental Normocalcemic Primary Hyperparathyroidism Presenting With Symptomatic Hypophosphatemia: A Case Report. [PDF]
Cureus, 2023 Normocalcemic primary hyperparathyroidism (NHPT) is a newly defined variant of primary hyperparathyroidism (PHPT). It’s defined by consistently normal total and ionised calcium levels with elevated parathyroid hormone in the absence of secondary causes ...

The effects of season (spring versus autumn) on diagnosis of normocalcemic primary hyperparathyroidism. [PDF]
Front Endocrinol (Lausanne), 2022 Background Raised parathormone (PTH) and normal calcium concentrations can be observed both in normocalcemic primary hyperparathyroidism (nPHPT) and in secondary hyperparathyroidism, e.g. due to vitamin D deficiency.
