Milk fever (MF) is a metabolic disease in dairy cows around parturition. The clinical lead sign is muscular paresis leading in severe cases to paralysis of the affected animal. Multiparturient animals of high performing dairy breeds are most likely to be affected and have a high probability of recurrence. An acute drop in blood calcium levels causes the disease when the demand for calcium at the onset of lactation exceeds the ability to replete blood calcium levels through mobilization from bone and intestinal uptake...

Calcium-sensing receptor(CaSR)is highly expressed in parathyroid, kidney, bone, and small and large intestines to regulate Ca homeostasis. Calcilytics are allosteric antagonists of CaSR, and stimulate endogenous PTH release. Several calcilytics have been evaluated as anabolic therapies for postmenopausal osteoporosis but clinical development of all of them has been abandoned because the lacked clinical efficacy. Calcilytics might be repurposed for new indications like autosomal dominant hypocalcemia or other disorders...

Sensing of extracellular calcium(Ca2+)levels involves the Ca-sensing receptor(CaSR), its downstream signaling molecule Gα11, and the adaptor-related protein complex 2(AP2)that plays a role in clathrin-dependent endocytosis of CaSR. Inactivating mutations in CaSR cause familial hypocalciuric hypercalcemia type 1(FHH1)and neonatal severe hyperparathyroidism(NSHPT), while activating mutations lead to autosomal dominant hypocalcemia type 1(ADH1)and Bartter syndrome type Ⅴ. Recent studies have identified that inactivating mutations in Gα11 and σ-subunit of AP2(AP2σ)also cause FHH, and these conditions have been classified as FHH2 and FHH3, respectively...

It is often difficult for terrestrial animals to take enough calcium. To maintain serum or extracellular calcium levels is very important for muscle and nerve function. Two major regulators to increase the serum calcium levels are parathyroid hormone(PTH)and vitamin D. PTH binds to the G protein coupling receptor, PTH1R, and increases intracellular cAMP levels. Impirement in the PTH signalling causes many diseases such as pseudohypoparathyroidism and acrodysostosis with hormone resistance. Vitamin D is activated to 1,25-dihydroxyvitamin D[1,25(OH)2D]by two steps of hydroxylation which occurs in the Liver and Kidney...

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...

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: Serum level of 25-hydroxyvitamin D (25-OHD) is considered as the most appropriate marker of vitamin D status. However, only a few studies have investigated the relationship between 25-OHD and parathyroid hormone (PTH) in children. To this end, this study was aimed at evaluating the lowest 25-OHD level that suppresses the production of parathyroid hormone in children. METHODS: A retrospective record review was performed for children aged 0.2 to 18 years (n=193; 106 boys and 87 girls) who underwent simultaneous measurements of serum 25-OHD and PTH levels between January 2010 and June 2014...
