Estimated Enrollment: 40
Study Start Date: October 1999
Detailed Description:

PROTOCOL OUTLINE: Patients undergo a 30-hour infusion of deuterated cortisol with peripheral and petrosal vein measurements of adrenocorticotropin hormone (ACTH) and corticotropin-releasing hormone (CRH). Patients also have a 2-day, low-dose dexamethasone suppression test.

Patients with ACTH tumors are referred for pituitary surgery as indicated. Patients without Cushing's syndrome are entered as controls. During scheduled radiologic procedures, these subjects undergo ACTH and CRH sampling from the petrosal vein or cavernous sinus following a deuterated cortisol infusion.

  Eligibility

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Criteria

PROTOCOL ENTRY CRITERIA:

Suspected adrenocorticotropin hormone (ACTH)-dependent Cushing's syndrome No pregnant women Effective contraception required of fertile women
