title: Investigation of adrenomedullary function in atopic dermatitis.
abstract: Adrenomedullary function in patients with atopic dermatitis was assessed by measurement of plasma levels of catecholamines (adrenalin and noradrenalin) and cyclic AMP in response to the stimuli of standing after lying supine, and a 5-min infusion of histamine in the standing position (i.e. histamine plus standing). Plasma clearance of adrenalin was examined by measurement of plasma catecholamine and cyclic AMP levels following a 15-min intravenous infusion of adrenalin in the supine position. Resting plasma levels of adrenalin, cyclic AMP and noradrenalin were not statistically different in atopic patients and normal controls. Standing or intravenous infusion of histamine in the standing position caused a rise in plasma catecholamine levels. Plasma adrenalin, cyclic AMP and noradrenalin levels in response to these stimuli and the rate of clearance of exogenous adrenalin from the plasma were not significantly different in patients with atopic dermatitis and in normal subjects.
