Background:Calcium-sensing receptors (CaSR) located on parathyroid glands and kidneys act to regulate serum calcium levels. Inherited hypocalciuric hypercalcaemia and autosomal dominant hypercalciuric hypocalcaemia are due to inactivating and activating CaSR mutations respectively. We present the immediate and medium term postoperative clinical course of the first paediatric patient with hypercalciuric hypocalcaemia managed with a simultaneous parathyroid and ...

Background: Patients with autosomal dominant hypocalcemia type 1 (ADH1), due to germline gain-of-function calcium-sensing receptor (CASR) mutations, have hypocalcemia and seizures, hyperphosphatemia, hypercalciuria and inappropriately low parathyroid hormone (PTH) concentrations. Treatment for ADH1 comprises calcium and vitamin D analogs, however, their use predisposes to nephrocalcinosis and renal impairment. In contrast, recombinant human PTH(1-34) may incre...
