title: Effect of angiotensin II on plasma ACTH in patients with Addison's disease.
abstract: Short-term angiotensin II (AII) infusions (3 ng/kg/min) were performed in 5 patients with Addison's disease in order to assess the effect of AII on ACTH secretion. Base line ACTH levels were elevated due to a 9-h time lag between hydrocortisone administration and onset of the study. In 2 separate infusion periods of 30-min duration, AII had no unidirectional effect on plasma ACTH. Mean ACTH increased slightly but insignificantly. Mean blood pressure rose by about 10 mmHg. The degree of angiotensinaemia induced is probably similar to the state of moderate to severe sodium deficiency. Short-term changes of AII in this order of magnitude have obviously no major effect on ACTH secretion.
