Abstract:
Abstract. It has been suggested that the renal kallikreinkinin system is dependent on mineralocorticoid activity. This hypothesis was studied in a patient with cyclic Cushing's syndrome combined with cortisol suppressible, dexamethasone non-suppressible ACTH secretion. The 24-h urinary excretions of sodium, potassium, cortisol, active and inactive kallikrein, aldosterone, and prostaglandin E 2 (PGE 2 ) were studied during normal and excessive cortisol secretion and after bilateral adrenalectomy. Kallikrein, PGE 2 and potassium rose during cortisol overproduction while aldosterone and sodium decreased. Kallikrein, PG E and potassium were positively related to cortisol excretion, whereas urinary aldosterone and sodium showed a negative relationship to cortisol. Kallikrein was inversely related to aldosterone. Excretion of inactive kallikrein followed closely the changes of active kallikrein. During cortisol excess, as in our patient, the mineralocorticoid activity of cortisol will exceed that of aldosterone. This suggests that the alterations in kallikrein, aldosterone and PGE 2 during cortisol excess in the present study were due to the mineralocorticoid potency of the steroid.
