Unraveling the Paradox of Vitamin D Status in Primary Hyperparathyroidism: An Incidental Finding or an Unexpected Consequence? [PDF]

Int J Mol Sci
Suboptimal vitamin D status is commonly observed in primary hyperparathyroidism but is rarely considered in management decisions. The present study aimed to bring additional insights on vitamin D status in primary hyperparathyroidism patients ...

Response to an oral calcium load in nephrolithiasis patients with fluctuating parathyroid hormone and ionized calcium levels

Brazilian Journal of Medical and Biological Research, 2004
the response to an oral calcium load test was assessed in 17 hypercalciuric nephrolithiasis patients who presented elevated parathyroid hormone (PTH) irrespective of the ionized calcium (sCa2+) levels. Blood samples were collected at baseline (0 min) and

Normocalcemic primary hyperparathyroidism; a mini-review

Journal of Parathyroid Disease, 2023
Normocalcemic primary hyperparathyroidism (NPHT) is a subtype of primary hyperparathyroidism (PHPT) characterized by elevated levels of parathyroid hormone (PTH) within the normal range of serum calcium. In traditional PHPT, high serum calcium levels are typically seen, whereas in normocalcemic PHPT, calcium levels are within the normal range.

Oral cinacalcet administration decreases serum ionized calcium and parathyroid hormone concentrations in healthy dogs

Journal of Veterinary Pharmacology and Therapeutics, Volume 47, Issue 4, Page 274-279, July 2024.
Abstract Cinacalcet is an oral calcimimetic that has potential to non‐invasively treat primary hyperparathyroidism in dogs (Canis lupis familiaris). There is minimal data assessing its efficacy in dogs. This study aimed to determine whether a single dose of cinacalcet decreases serum ionized calcium (iCa), total calcium (tCa), and parathyroid hormone ...

Heterogeneous parathyroid near‐infrared autofluorescence patterns are associated with single adenomas in primary hyperparathyroidism

Head &Neck, Volume 46, Issue 3, Page 592-598, March 2024.
Abstract Background Primary adenoma (PA) and multi‐gland hyperplasia (MGH) account for 85% and 15% of primary hyperparathyroidism (PHPT) cases, respectively. Near‐infrared autofluorescence (NIRAF) enhances intraoperative parathyroid identification. We hypothesized that PA would display a more heterogeneous NIRAF pattern compared to MGH.

Normocalcemic hyperparathyroidism : study of its prevalence and natural history [PDF]

, 2020
Context Normocalcemic hyperparathyroidism (NPHPT) is characterized by persistently normal calcium levels and elevated parathyroid hormone (PTH) values, after excluding other causes of secondary hyperparathyroidism. The prevalence of the disease varies

Calcium-sensing receptor: Role in health and disease

Indian Journal of Endocrinology and Metabolism, 2012
The calcium-sensing receptor (CaSR) is a 1,078 amino acid G protein-coupled receptor (GPCR), which is predominantly expressed in the parathyroids and kidney.

Recurrent Urolithiasis Revealing Primary Hyperparathyroidism in a Nephrology Department

Case Reports in Nephrology, Volume 2024, Issue 1, 2024.
Background. Urinary lithiasis constitutes a recurrent pathology affecting a relatively young population. The risk of progression to chronic renal failure and the cost of treatment are the most important issues. Primary hyperparathyroidism (PHPT) is responsible for urolithiasis and nephrocalcinosis in 7% of patients, and it represents the 7th cause of ...

Investigating patients with normocalcemic hyperparathyroidism: When is a parathyroid scintigraphy indicated?

World Journal of Nuclear Medicine, 2019
In clinical practice, physicians often encounter patients with persistent elevated serum parathyroid hormone levels and normal serum calcium levels, a state known as normocalcemic hyperparathyroidism (NHPT).
