[Ketoconazole in the control of arterial hypertension in Cushing's syndrome].

OBJECTIVE: To determine the usefulness of ketoconazole for the control of arterial hypertension (AH) in Cushing syndrome (CS) as temporary treatment. PATIENTS AND METHODS: Fifteen cases of CS were collected (eleven cases of Cushing disease, two cases of ectopic secretion of ACTH, one case of adrenal adenoma, and one case of adrenal carcinoma). The clinical characteristics as well as laboratory data of patients with AH and the response to therapy were studied. RESULTS: Six patients (40%) had AH. A significant difference was observed of an older age, a higher frequency of association with diabetes mellitus and a higher 24 hour free urine cortisol (FUC) for patients with AH compared with non hypertensive patients. Ketoconazole was efficient for controlling AH in five cases, and in all of them the return to normal levels of 24 hour FUC was achieved. A failure of AH control under treatment with ketoconazole occurred in the only case of adrenal carcinoma. There was no significant secondary adverse reaction to ketoconazole. CONCLUSIONS: Ketoconazole is an efficient drug for the control of AH in CS and is well tolerated. In our series, the return to normal levels of FUC was associated with control of AH.
