Abstract

Idiopathic hypoparathyroidism is a relatively rare disease characterized by hypocalcemia and hyperphosphatemia: this is due to a deficiency or a sereretory disorder of the parathyroid hormone without any prior operation nor underlying medical disoder. Calcium carbonate and vitamin D substitution are generally considered as the mainstay of therapy, but these treatments can cause hypercalcemia and hypercalciuria. Persistent ingestion of large amount of calcium carbonate can cause milk-alkali syndrome that is characterized by hypercalcemia, metabolic alkalosis and renal failure. Once a patient is diagnosed with milk-alkali syndrome, withdrawal of calcium carbonate and vitamin D is essential and treatment with saline diuresis and furosemide is the usually effective. In treatmenf of hypoparathyroidism with calcium carbonate and vitamin D substitution, evaluation of serum calcium and urinary calcium excretion is essential to avoid hypercalcemia and ypercalciuria. We concluded that during treatment with calcium carbonate and vitamin D substitution for patients with idiopathic hypoparathyroidism, they should have carefully laboratory monitoring, and they should be made aware of the circumstances influencing calcium metabolism
