Background: RACE is an open-label study that assessed the long-term safety and efficacy of recombinant human parathyroid hormone 1–84 (rhPTH[1–84]) for the treatment of hypoparathyroidism in adults (ClinicalTrials.gov identifier NCT01297309). Here, we present 6-year safety and efficacy data.Methods: Patients initially received 25 or 50 μg of rhPTH(1–84) subcutaneously, once daily, with stepwise dose adjustments of 25 μg (up or do...

Background: Primary hyperparathyroidism (PHPT) has been linked to glucose homeostasis disorders, leading to insulin resistance and type 2 diabetes mellitus. Previous small studies evaluating the effect of parathyroidectomy (PTX) on various parameters of glucose metabolism have produced conflicting results. The impact of PTX on incretin hormone levels has not been studied yet. The aim of this pilot study was to investigate the effect of PTX on markers of glucose metabolism and ...

Introduction: Persistent primary hyperparathyroidism (pHPT) occurs in 2.5 to 15% of cases after parathyroidectomy. Pre-operative localization studies (usually 99mTc-MIBI and cervical ultrasonography (US)) allow focused surgical approach (unilateral neck exploration or minimally invasive parathyroidectomy). Few studies have evaluated the best pre-reoperative approaches in case of persistent sporadic pHPT. The aim of our study is to evaluate the value of a second pre-...

Background: The diagnosis of PHPT and chronic HypoPT is still challenging, mainly due to the wide spectrum of clinical and biochemical presentation and the lack of validated diagnostic index in literature. The serum Ca/P ratio has been proposed as an accurate tool to diagnose PHPT in a small sample of patients, while no data is available about its possible application for HypoPT.Aim: To validate the serum Ca/P ratio as a diagnostic index for PHPT and to ...

Introduction: The gold standard for evaluating Occult Parathyroid Adenomas (OPa) in patients with biochemical pattern of primary hyperparathyroidism (PHPT) is the 99mTc-MIBI parathyroid scan. 18F-Fluorocholine (18F-FCH) PET/CT has been proposed as a potential technique for detection and localization of OPa when 99mTc-MIBI scan is negative or inconclusive.Aims: To evaluate sensitivity and positive predictive value of 18F-Fluorocholine PET/CT in patients w...

Background: The normocalcaemic hyperparathyroidism (NHPT) has been defined as a condition with persistently normal total and ionized calcium levels in the presence of high levels of PTH. The clinical aspects of NHPT have been evaluated in different cohorts but the interpretation of these findings is confounded by differing methods used to rule out secondary hyperparathyroidism and by the small number of NHPT subjects enrolled. Up to now, there is no information available that ...

Hypoparathyroidism (HP) is a rare disease characterized by an absence or inappropriately low concentrations of circulating parathyroid hormone, leading to hypocalcaemia, hypophosphatemia and elevated urinary calcium excretion.Aim: To determine complications in chronic post-surgical HP patients.Material and methods: We have analyzed the data from 76 patients (71 women and 5 men; median age 51.8 years (range 18–77)) with chronic...

Worldwide, a care gap has been recognized between presenting with a fragility fracture and prevention of the next fracture. Fracture Liaison Service is the most cost-effective method to close this gap, but its implementation is sparse in many countries. To assess the need for a subsequent fracture prevention program in Denmark, we conducted a cross-sectional study – named OFELIA - aiming to estimate the prevalence of osteoporosis in a Danish cohort of fragility fracture p...

Introduction: Sporadic primary hyperparathyroidism (sporadic PHPT) is a common endocrine disorder, usually caused by a single parathyroid adenoma. However, up to 15% of patients present with multiple gland disease (MGD), which cannot be always diagnosed preoperatively, raising serious management problems. No predictive genetic screening tests are currently available to distinguishing adenomas from MGD in sporadic PHPT. MiRNAs are widely established as genetic molecules that ha...

Objective: Primary hyperparathyroidism (PHPT) is associated with increased cardiovascular morbidity including hypertension with a prevalence ranging from 40 to 65%. The renin-angiotensin-aldosterone system (RAAS) is a key system in the regulation of sodium/potassium balance, volume homeostasis as well as blood pressure. There is increasing evidence of interactions between calcium and calcium-regulatory hormones with the RAAS. The aim of this study was to investigate the associ...

Significant knowledge gaps exist regarding the humanistic effects of hypoparathyroidism, a rare, debilitating disorder. We report results from a global survey to characterise the burden of hypoparathyroidism from the patient perspective. An anonymous survey was conducted in patients with uncontrolled chronic hypoparathyroidism (as determined by patients’ report of persistent symptoms and/or poorly controlled calcium levels as told by their physician) despite receiving con...
