What this trial studies

This observational study aims to follow participants diagnosed with Cushing's syndrome throughout their routine care, creating a comprehensive data registry to analyze long-term outcomes. Participants will be assessed using various quality of life and psychological questionnaires, including the Cushing's QoL, Nottingham Health Profile, and Hospital Anxiety and Depression Scale. The study seeks to gather valuable information that can enhance understanding of the condition and improve patient care.

Why it matters

Potential benefit: If successful, this study could provide insights that lead to improved management and treatment strategies for patients with Cushing's syndrome.

How similar studies have gone: Other studies focusing on patient registries for chronic conditions have shown success in improving treatment outcomes and understanding disease progression.

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Age 14 or older
* Active or treated overt Cushing's (due to pituitary, ectopic, or adrenal tumor), mild adrenal Cushing's syndrome (MACS), or a silent corticotroph tumor
* The diagnosis of CS or MACS will be made by the PI, based on the below Endocrine Society guidelines, the patient's clinical presentation, and the PI's judgment.

  * Diagnostic criteria for ACTH-dependent Cushing's are according to the Endocrine Society and European Society of Endocrinology guidelines and include: Elevated 24-hour urinary free cortisol (UFC), normal or elevated plasma ACTH, elevated midnight salivary cortisol levels, or classic dexamethasone suppression testing for CD (morning cortisol \> 5 ug/dL after 1 mg overnight of classic 2-day low dose test) and a pituitary lesion on MRI (in the case of pituitary Cushing's). If patient does not have any of these results, pathology of ACTH tumor may confirm presence of disease.
  * Diagnostic criterion for MACS is according to the European Society of Endocrinology guidelines: Classic dexamethasone suppression testing for CS (morning cortisol \>1.8 µg/dL after 1 mg overnight) and the presence of an adrenal adenoma.
* Silent corticotroph tumors will be defined by surgical pathology demonstrating positivity for ACTH, in the absence of clinical and biochemical features of Cushing's syndrome.
* In lieu of MRI, surgical, or laboratory reports, physician's assessment note including mention of results will also be used as source for eligibility purposes.

Exclusion Criteria:

* Patients with a diagnosis of iatrogenic Cushing's.
