Hypoparathyroidism is a rare disorder characterized by low serum calcium levels and high serum phosphate levels. This disease is commonly treated with calcium supplements and active vitamin D metabolites or analogues, but large doses of these supplements are often utilized to relieve the symptoms caused by hypocalcemia, without guarantee of a physiological normalization of calcium-phosphate homeostasis. Areas covered: Several studies have investigated replacement therapy with recombinant human PTH [rhPTH (1-84) and rhPTH (1-34)] for subjects with hypoparathyroidism...

A 26-year-old Japanese woman presented with adrenal insufficiency, and treatment was started with cortisone and fludrocortisone in 1975. A few years later, she presented with hypoparathyroidism and was diagnosed with autoimmune polyendocrine syndrome type I (APS I), and treatment with calcium and alfacalcidol was started. She was found to have subacute thyroiditis and relative adrenal failure in 2006. Her condition remained stable under treatment with cortisone, fludrocortisone, levothyroxine, calcium lactate, precipitated calcium carbonate and alfacalcidol...

Context: Options for chronic treatment of hypoparathyroidism include calcitriol, recombinant human parathyroid hormone and high dose vitamin D (D2). D2 is used in a minority because of fear of prolonged hypercalcemia and renal toxicity. There is a paucity of recent data about D2 use in hypoparathyroidism. Objective: Compare renal function, hypercalcemia and hypocalcemia in patients with hypoparathyroidism treated chronically with either D2 or calcitriol. Design, setting, patients: A retrospective study of patients with hypoparathyroidism treated at University of Maryland Hospital...

PURPOSE OF REVIEW: Permanent hypoparathyroidism is the most common long-term complication after total thyroidectomy and it can cause significant morbidity and increased costs. Its incidence varies from 30% to 60%. RECENT FINDINGS: The surgical technique and the extent of thyroidectomy are related to parathyroid injury and hypoparathyroidism. The glands should be identified in situ, carefully manipulated and preserved, as well as their vascularization. In case of incidental removal, routine autotransplantation is advocated...

Biomimetic parathyroid regeneration with sustained release of parathyroid hormone (PTH) into the blood stream is a considerable challenge in hypoparathyroidism treatment. We recently reported that tonsil-derived mesenchymal stem cells (TMSC), if these cells were both differentiated in vitro before implantation and incorporated into a scaffold Matrigel, are a good cell source for parathyroid regeneration in a parathyroidectomized (PTX) animal model. Here, we present a new strategy for improved clinical application that enhances the sustained release of PTH by controlling mechanical stiffness using in situ-forming gelatin-hydroxyphenyl propionic acid (GH) hydrogels (GHH)...

BACKGROUND: Hypoparathyroid patients often have a higher bone mineral density (BMD) than the general population. However, an increase in BMD does not necessarily correlate with a solid bone microstructure. This study aimed to evaluate the bone microstructure of hypoparathyroid patients by using hip structure analysis (HSA). METHODS: Ninety-five hypoparathyroid patients >20 years old were enrolled and 31 of them had eligible data for analyzing bone geometry parameters using HSA...

INTRODUCTION: Parathyroid damage or unintentional excision still affect thyroid surgery and may cause permanent hypoparathyroidism. The only way to recover the excised or ischemic gland functionality is still reimplantation. Many sites of reimplantation have been described, each of one showing both advantages and drawbacks. The aim of this study is to verify results of a new procedure called PR-FaST: Parathyroid Reimplantation in Forearm Subcutaneous Tissue, in a series of unselected patients after long-term follow-up...
