ETHINYLOESTRADIOL IN THE PRE-OPERATIVE TREATMENT OF A SEVERE CASE OF CUSHING'S SYNDROME DUE TO ADRENOCORTICAL HYPERPLASIA
ABSTRACT An extremely severe case of Cushing's syndrome due to adrenocortical hyperplasia is presented. The patient was treated with 0.5 mg of ethinyloestradiol four times daily for 106 days with short interruptions. The treatment caused a clinical remission with correction of the abnormal biochemical characteristics of the disease. The output of corticosteroids fell markedly, and the maximal response capacity of the adrenal cortex was reduced. Stressful stimuli continued to elicit an increase in corticosteroid excretion, and the pituitary-adrenal feed-back mechanism was preserved at the lower level of adrenocortical activity. It became evident, however, that the treatment in this patient did not provide a complete cure, and bilateral adrenalectomy was performed. Further trial with oestrogen treatment in this disease is recommended.
