Summary
This study looks at the long-term health of people who were cured of Cushing disease before age 21. Researchers want to understand how past high cortisol levels affect the body and mind years later. Participants will complete surveys and have check-ups every 5 years. The goal is to learn about lasting effects, not to test a new treatment.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The study population will consist of patients that were previously successfully treated for CD before the age of 21 years. We aim to identify these patients through review of our current protocol 97-CH-0076 on Clinical and genetic investigation of pituitary and hypothalamic tumors , which has been recruiting patients since 1997. We will also accept patients who have been diagnosed and successfully treated for pediatric CD at outside institutions after reviewing the medical records and confirming their diagnosis. The patients must be normocortisolemic at the time of their recruitment. Family members of subjects who are survivors of pediatric Cushing disease will be invited to participate in the DNA/linkage analysis study.

* INCLUSION CRITERIA: 1. Males and females 10-42 years old (subjects) who were previously diagnosed and had successful treatment of CD before the age of 21 years old. Patients who have undergone therapies other than surgical resection (such as radiation or medical treatment) will be eligible to participate. 2. Normocortisolemia or hypocortisolemia at the time of the study (as documented within past 6 months of recruitment) documented as urine free cortisol or midnight/afternoon serum or salivary cortisol levels within or below the normal range or documented panhypopituitarism (on glucocorticoid replacement). 3. Patients or a legal guardian (in case of cognitively impaired adults or children) must provide assent/consent at the time of the recruitment. 4. Family members (2- 90 yrs.) of patients with a family history of pituitary tumors and who agree to participate in the DNA/linkage analysis study. EXCLUSION CRITERIA: 1. Pregnancy 2. Patients with any medical, physical, psychiatric, or social conditions, which, in the opinion of the investigators, would make participation in this protocol not in their best interest, will be excluded from the on-site visit of the study. Patients who are critically ill, unstable, or with severe organ failure that may affect/limit the endocrine evaluation and place unsustainable demands on Clinical Center or NICHD resources will be excluded. They will still be offered the opportunity to participate in the online questionnaire part of the study.
