Remission of idiopathic hypoparathyroidism during lactation: a case report

A 35-year-old woman with idiopathic hypoparathyroidism achieved a spontaneous remission during lactation even though 1-alpha-hydroxyvitamin D3 therapy was discontinued after delivery. Urinary excretion of cyclic adenosine 3',5'-monophosphate and phosphate was significantly increased during lactation, probably in response to the increased levels of circulating parathyroid hormone-related protein derived from the breast tissue.
