Study of Endocrine-Related Conditions and Physiology

Endocrine Disease

Adrenal Gland, Pituitary, Natural History

Background: Endocrine disorders involve changes to glands that produce hormones. Hormones are released by these glands into the blood so they can direct the function of other tissues in the body. Researchers want to study people who may have endocrine disorders. They want to learn more about the conditions that affect endocrine glands. Objective: To study adults with a variety of endocrine disorders for research and physician education. Eligibility: Adults ages 18 and older who have an endocrine or metabolic-related disorder Healthy volunteers 18 and older Design: Participants will be screened with a review of their medical records. Participants will have a physical exam and medical history. The length of the study and the schedule will vary by participant. Tests may include: Blood and urine tests Stool and saliva samples Imaging studies: Participants will lie on a table while a machine takes pictures of the body. They may be injected with a substance to make their organs more visible in the pictures. Tests of endocrine tissue function Consultation with other specialists Sleep study Medical photographs Participants may be treated for their endocrine disorder. This could include: Surgery. If tissue is removed during surgery, it may be studied. Radiation Medicine Participants may have genetic testing. This will be done with a small amount of blood, cells from a cheek swab, or saliva.

Study Description: This study allows the NIH Intramural Endocrinology Training Program (IETP) to follow or provide evaluation, treatment and or interventions to certain eligible subjects. Objectives: 1. To provide a repository of data and samples obtained during the course of clinical care to allow for future research. 2. To add value to the IEFP training program by maintaining a diverse group of endocrine conditions seen at the NIH. 3. To provide a vehicle by which pilot studies of endocrine physiology can be initiated. 4. To identify prismatic cases that deviate from known presentations or responses to treatment. 5. To evaluate the safety and results from adrenal venous sampling using a modified catheter with side hole placement. Endpoints: 1. Data from standard of care evaluation and management. 2. Adverse events during and after adrenal vein sampling; cortisol and aldosterone results from the sampling.
