Abstract
The adrenal gland functional reserve was studied in a group of 22 patients with active paracoccidioidomycosis before therapy and in 18 of the same patients after termination of six months of ketoconazole treatment. 22 control subjects were also tested. Serum cortisol was measured before and after i.v. infusion of 250 micrograms of corticotropin given over a period of two hours. Basal cortisol levels were subnormal in only one patients before treatment and in four of 18 patients after therapy. Overt Addison's disease was found in 14% of the patients before treatment. However, corticotropin stimulation revealed diminished adrenal reserve in 23% of patients before, and in 44% of the patients after treatment. Although decreased adrenal cortex function after therapy may be influenced by ketoconazole, more studies are needed to determine the role of this agent after prolonged use. The high frequency of subclinical adrenal failure in paracoccidioidomycosis should alert clinicians in charge of such patients, should they face physiological stress.
