Treatment of Cushing’s Syndrome
Treatment of Cushing’s syndrome focuses on reducing excess cortisol and addressing the root cause of the hormonal imbalance. The approach depends on whether the condition is caused by corticosteroid medication, a tumour, or another hormonal disorder. With appropriate treatment, most individuals with Cushing’s syndrome can return to normal hormone levels and regain their health.
Stopping or Reducing Corticosteroids
For individuals whose condition is caused by long-term corticosteroid use:
Gradual tapering of the medication under medical supervision is essential
The goal is to reduce dosage while still managing the underlying condition (e.g. asthma, lupus)
Stopping corticosteroids abruptly can be dangerous, as the body may no longer produce enough natural cortisol
Surgery | Treatment of Cushing’s Syndrome
If a tumour is causing the excess cortisol, surgery is usually the first-line treatment:
Transsphenoidal surgery: A minimally invasive procedure to remove pituitary adenomas
Adrenalectomy: Removal of one or both adrenal glands if an adrenal tumour is present
Removal of ectopic ACTH-secreting tumours, such as in the lungs or pancreas
Radiation Therapy
Used if pituitary surgery is unsuccessful or not possible:
Stereotactic radiosurgery targets the tumour while sparing surrounding tissue
May take months to become effective, requiring interim medication to control cortisol
Medications
If surgery or radiation isn’t feasible or cortisol levels remain high post-treatment, medications may help:
Ketoconazole, metyrapone, or osilodrostat: Suppress cortisol production
Mifepristone: A glucocorticoid receptor blocker, useful in controlling symptoms like high blood sugar
Regular monitoring is essential due to potential side effects
Hormone Replacement
After surgery or prolonged suppression, individuals may need temporary or permanent cortisol replacement therapy (e.g. hydrocortisone) to avoid adrenal insufficiency.
Supportive Care
Management of blood pressure and blood sugar
Nutritional support and bone-strengthening therapies
Psychological counselling to address mood disorders
In summary, treatment of Cushing’s syndrome requires a tailored plan depending on the cause. With the right interventions—be it surgical, medical, or hormonal—most individuals can recover or significantly improve.
