Urinary Free Cortisol Is Not a Biochemical Marker of Hypertension

We found an EH subpopulation with abnormally high values of UFF but evidence of only a minor mineralocorticoid action, which was not directly related to the BP elevation, suggesting that another alternative mechanism could be triggering the F-induced hypertension. The origin of hypercortisoluria was not elucidated; however, a subtle glucocorticoid resistance was found in some cases.
