Normal Free Fatty Acid Response to Isoproterenol in Pseudohypoparathyroidism*

Open publisher page 8 citations

Abstract

The lipolytic response to isoproterenol infusion was examined in seven normal subjects and six patients with pseudohypoparathyroidism type I [two had deficiency of the hormone receptor-cyclase coupling protein (N-protein) and four did not]. Despite blunted plasma cAMP responses to isoproterenol in both subgroups of pseudohypoparathyroidism patients, the serum FFA responses were normal. We conclude that changes in plasma cAMP do not reflect the adequacy of the lipolytic response to isoproterenol.
