Abstract / Description of output

In an attempt to evaluate possible adrenal abnormalities in Alzheimer's disease (AD), prestimulus levels and ACTH-stimulated serum levels of steroid hormones, corticosteroid-binding globulin (CBG), and insulin-like growth factor I (IGF-I) were measured in 18 patients with early AD (8 men, 10 women; 74.6 +/- 6.5 years, mean +/- SD) and 19 healthy controls (10 men, 9 women; 74.2 +/- 7.6 years, mean +/- SD). Steroid hormone levels were measured before and after an intravenous bolus injection of 250 mu g ACTH. AD per se had an independent influence on hormone levels when evaluated in MANOVA models. AD patients had significantly higher prestimulus levels of dehydroepiandrosterone and androstenedione (p = .04 and p = .003, respectively) with accentuated differences after ACTH (p = .02 and p < .001 for peak responses, respectively). Serum levels of cortisol, CBG, free cortisol, 17 alpha-hydroxyprogesterone (17 alpha-OHP), and IGF-I did not differ between groups. These abnormalities may have implications for neuronal degeneration as well as for behavioural symptoms in AD.
