From: Hypercortisolism in patients with cholestasis is associated with disease severity
Baseline cortisol (A) as well as maximal cortisol levels after ACTH stimulation (B) are elevated in patients with cholestasis. Adrenocorticotropic hormone (ACTH) levels are not increased (C) indicating effects other than stimulation of the pituitary gland. Delta cortisol levels, reflecting the cortisol increase after diagnostic stimulation with ACTH, were comparable between both groups (D) definitively excluding adrenal insufficiency in patients with cholestasis
