Abstract
The possible role of Vasoactive Intestinal Peptide (VIP) and Peptide H istidine Methionine (PHM) as neuromodulators of anterior pituitary fun ction in humans has been suggested. In this work the effects of VIP an d PHM on basal and CRH-stimulated ACTH/F secretion were studied in 7 p atients with Gushing's disease. An ACTH/F response was found in 3 case s during PHM infusion and in 2 of 6 patients during VIP infusion. When compared to CRH alone, a blunted ACTH response to CRH during PHM occu rred in 5 tested patients and during VIP in 3 cases. In conclusion, VI P and PHM are able to rise ACTH/F secretion in some patients with Gush ing's disease, but are unable to potentiate the response to CRH, which rather may be reduced.
