1 Effects of theophylline infusion on the growth hormone (GH) and prolactin response to GH-releasing hormone administration in acromegaly. Theophylline growth hormone 1 Homo sapiens
2 Since theophylline has been shown to blunt the GH response to growth hormone-releasing hormone (GHRH) in normal subjects, we investigated whether the same effect of theophylline administration could be reproduced in patients with active acromegaly. Theophylline growth hormone 1 Homo sapiens
3 However, the amount of GH released after GHRH stimulation was lower when theophylline was concomitantly infused (7525 +/- 3709 ng min/ml vs. 12038 +/- 6337 ng min/ml; p less than 0.05). Theophylline growth hormone 1 Homo sapiens
4 Our results demonstrate that in active acromegaly theophylline blunts the GH response to GHRH, though this effect is not uniformly seen in all patients. Theophylline growth hormone 1 Homo sapiens
