  Purpose

OBJECTIVES: I. Study the relationship between dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis and disorders of mood, vegetative function, and cognition in patients with Cushing's disease.

II. Identify subgroups of patients with Cushing's disease who differ in the presence and severity of the depressive syndrome, and uncover HPA axis dysregulation differences among them using corticotropin-releasing hormone, metyrapone, and dexamethasone challenge testing.

Estimated Enrollment: 8
Study Start Date: July 1994
Detailed Description:

PROTOCOL OUTLINE: All patients receive a psychiatric evaluation at baseline, as well as assessments of plasma adrenocorticotropin, beta lipotropin, beta endorphin, and cortisol, and urinary cortisol. Peptide and steroid assays are performed, alone and in response to corticotropin-releasing hormone, metyrapone, and dexamethasone. Patients are given sleep electroencephalograms at baseline and 1 year following treatment.

A weight maintenance diet is prescribed for all patients.
