Blunted plasma cyclic adenosine monophosphate response to isoproterenol in pseudohypoparathyroidism. 1983

H E Carlson, and A S Brickman

Plasma cAMP, serum glucose, and cardiovascular responses to isoproterenol infusion were examined in seven normal subjects and seven patients with pseudohypoparathyroidism (PHP), type I (three with deficiency of the hormone receptor-cyclase coupling protein (N-protein) and four who were N-protein replete). Although plasma cAMP responses were blunted in both subgroups of PHP patients, the cardiovascular and glucose responses to isoproterenol were normal. We conclude that the blunted plasma cAMP response to isoproterenol in PHP does not depend on deficient N-protein coupling of adenylate cyclase to the beta-adrenergic receptor and that the cardiovascular and glucose responses to isoproterenol are not reflected in changes in plasma cAMP.

D010281 Parathyroid Hormone A polypeptide hormone (84 amino acid residues) secreted by the PARATHYROID GLANDS which performs the essential role of maintaining intracellular CALCIUM levels in the body. Parathyroid hormone increases intracellular calcium by promoting the release of CALCIUM from BONE, increases the intestinal absorption of calcium, increases the renal tubular reabsorption of calcium, and increases the renal excretion of phosphates.

D011547 Pseudohypoparathyroidism A hereditary syndrome clinically similar to HYPOPARATHYROIDISM. It is characterized by HYPOCALCEMIA; HYPERPHOSPHATEMIA; and associated skeletal development impairment and caused by failure of response to PARATHYROID HORMONE rather than deficiencies. A severe form with resistance to multiple hormones is referred to as Type 1a and is associated with maternal mutant allele of the ALPHA CHAIN OF STIMULATORY G PROTEIN.
