Abstract
ABSTRACT In order to verify its clinical usefulness, the ACTH test was performed in a series of 34 proved cases of adrenocortical hyperfunction and hypofunction. The results were above the previously established upper fiducial limit of normal response in the cases of hyperfunction, and below the lower limit in the cases of hypofunction. The present study confirms the findings of earlier investigators, that adrenocortical adenoma and adrenocortical hyperplasia with Cushing's syndrome exhibit different reaction patterns to stimulation with ACTH. In addition, the existence of patients with a normal resting excretion of corticosteroids but complete lack of adrenocortical reserve capacity was confirmed. Sixty-six patients with at least one of the following six classic symptoms of Addison's disease (loss of weight, weakness, hyperpigmentation, hypotonia, hypoglycemia, and disturbance in electrolyte and/or water metabolism) were studied clinically and with the aid of the ACTH test. The clinical investigation exc...
