[Pseudohypoparathyroidism and adrenal cortex insufficiency. A case of multiple endocrinopathy due to peripheral hormone resistance].

Since his childhood a now 31-year-old male showed typical symptoms of parathyroid hormone deficiency with hypocalcemia and hyperphosphatemia. We found a target organ resistance to parathyroid hormone and diagnosed pseudohypoparathyroidism. In addition adrenal insufficiency with hypocortisolism was seen. Both hormone systems act by stimulating adenylate cyclase. A defective receptor-adenylate cyclase complex may cause this--for the first time described--combination of endocrine insufficiency.
