Introduction: Hypoparathyroidism (HPT), pseudohypoparathyroidism (PHP), and end-organ parathyroid hormone (PTH)-resistance are rare metabolic disorders characterized by low serum calcium and increased serum phosphorus due to a PTH-deficient or resistant state. Various genes/loci have been identified as responsible for the development of congenital/familial forms of HPT, PHP and related diseases.Patients and Methods: A total of 39 patients with a clinical...

Introduction: Hypoparathyroidism (HypoPT) is a rare endocrine disease and Post-surgical HypoPT (PS-HypoPT) is the most common cause, caused by accidental parathyroid injury. From a neuropsychological standpoint, patients with PS-HypoPT present cognitive and neuropsychological symptoms. Irisin is a myokine secreted by contracting muscle, which mediates beneficial effects on several targets, including brain. The aim of this study was to evaluate irisin in the context of PS-HypoP...

Background: Glucocorticoids are crucial for treating various medical conditions due to their beneficial immunosuppressive effects. However, glucocorticoids also carry a high risk for osteoporosis. Notably, within just a few months of glucocorticoid therapy, bone density can be significantly reduced, and up to 5% of patients undergoing such treatment may experience fractures. There is promising evidence from preclinical studies and observations in patients with type 2 diabetes ...

Primary hyperparathyroidism (PHPT) is rare in the pediatric population, with an estimated incidence of 0.5–5 cases per 100,000 person-years in children. Data regarding the clinical phenotype, the surgical outcomes are scarce. The objective of our study was to retrospectively analyze the phenotype of apparently sporadic PHPT in patients ≤21 years in major endocrinology reference centers in Italy. None of the patients had known familial syndromes. A total of 41 patien...

Background and Aim: Primary hyperparathyroidism (PHPT) is a common endocrine disorder. A small proportion of these patients may have syndromic conditions such as multiple endocrine neoplasia (MEN) or familial hypocalciuric hypercalcemia (FHH). The UK national guidelines recommend genetic testing for familial hyperparathyroidism in individuals under 50 or any age with specific criteria such as family history, multi glandular disease, hyperplasia, or parathyroid carcinoma. Genet...

Introduction: Patients with transfusion-dependent β-thalassemia (TDT) frequently exhibit elevated urinary calcium excretion, contributing to kidney stone formation and osteoporosis. The underlying mechanism of hypercalciuria in β-thalassemia remains elusive, with FGF23 playing a potential role. FGF23, a bone-derived hormone, primarily acts on the kidneys by inhibiting phosphate reabsorption in the proximal tubules while enhancing calcium uptake in the distal tubules....
