Adipose tissue 11beta-hydroxysteroid dehydrogenase type 1 expression in obesity and Cushing's syndrome.

Objective: To evaluate the expression of 11beta-hydrxysteroid dehydrogenase type 1 (11beta-HSD1) in omental adipose tissue of patients with Cushing's syndrome and simple obesity, compared with normal weight controls.

Design And Methods: We have performed a case-control study and studied omental adipose tissue from a total of 24 subjects (eight obese subjects, ten patients with Cushing's syndrome due to adrenal adenoma, and six normal weight controls). Body mass index, blood pressure, plasma glucose, plasma insulin, plasma cortisol, urinary free cortisol and post dexamethasone plasma cortisol were measured with standard methods.
