Growth hormone secretory status is a determinant of the thyrotropin response to thyrotropin-releasing hormone in euthyroid patients with hypothalamic-pituitary disease. 1981

W E Cobb, and S Reichlin, and I M Jackson

To assess the influence of endogenous GH secretion on the TSH and T3 responses to TRH administration in patients with hypothalamic-pituitary disease, we analyzed tests in a selected group of 26 euthyroid patients with hypothalamic-pituitary disease and in 15 normal controls. Basal TSH levels and the TSH response to TRH were significantly greater in GH-deficient patients (group 1) than in patients with normal anterior pituitary function and unimpaired GH reserve (group II). However, the T3 response to TRH was significantly less in group 1 than in group II patients. In acromegaly (group III), the TSH response to TRH was blunted, while basal and stimulated T3 levels were no different compared to control levels. These findings suggest that endogenous GH depresses the TSH response to TRH while enhancing the thyroid secretion of T3 in response to the evoked TSH released.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D010900	Pituitary Diseases	Disorders involving either the ADENOHYPOPHYSIS or the NEUROHYPOPHYSIS. These diseases usually manifest as hypersecretion or hyposecretion of PITUITARY HORMONES. Neoplastic pituitary masses can also cause compression of the OPTIC CHIASM and other adjacent structures.

D013006	Growth Hormone	A polypeptide that is secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Growth hormone, also known as somatotropin, stimulates mitosis, cell differentiation and cell growth. Species-specific growth hormones have been synthesized.

D013972	Thyrotropin	A glycoprotein hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Thyrotropin stimulates THYROID GLAND by increasing the iodide transport, synthesis and release of thyroid hormones (THYROXINE and TRIIODOTHYRONINE). Thyrotropin consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the pituitary glycoprotein hormones (TSH; LUTEINIZING HORMONE and FSH), but the beta subunit is unique and confers its biological specificity.
