Abstract

A strong relationship has been found between arginine-vasopressin (AVP) and hypothalamus-pituitary-adrenal axis in humans. The aim of the current study was to evaluate baseline and CRH-stimulated ACTH and F levels in patients with central diabetes insipidus (CDI), before and after replacement therapy with desamino-D-AVP (DDAVP). Twenty-five patients with CDI, and 25 sex- and age- and BMI-matched healthy subjects entered the study. A standard CRH test (measurement of plasma ACTH and serum F before and every 15 min for 2 h after the administration of 100 μg of human CRH) was performed in all subjects. In patients with CDI, CRH test were repeated after 1 week of DDAVP at standard doses. At study entry, ACTH and F levels were significantly higher in patients with CDI than in controls either at baseline (ACTH: 45.5±4.8 vs 18.5±3.3 ng/l, p
