High cortisol, also known as hypercortisolism or Cushing's syndrome, is treated by addressing the underlying cause and managing the effects of excess cortisol. Treatment options include observation, medication, and surgery, selected based on the origin and severity of the condition.
Here's a breakdown of treatment approaches:
-
Observation:
- For mild cases of hypercortisolism, particularly those suspected to be cyclical, a doctor may simply monitor the patient's cortisol levels and symptoms over time to determine if active intervention is necessary.
-
Medication:
- Medications aim to control cortisol production or its effects. Some examples include:
- Ketoconazole: An antifungal medication that inhibits cortisol production.
- Metyrapone: Another medication that reduces cortisol production.
- Mitotane: A drug that can destroy cortisol-producing cells in the adrenal glands; generally reserved for more severe cases.
- Pasireotide: A somatostatin analog that can be used if Cushing's disease is caused by a pituitary tumor.
- Osilodrostat: Another medication to block cortisol production.
- Relacorilant: Cortisol receptor blocker.
- Medications aim to control cortisol production or its effects. Some examples include:
-
Surgery:
- Pituitary Tumors: If a pituitary tumor (Cushing's disease) is the cause, transsphenoidal surgery (removal of the tumor through the nose) is often the first-line treatment.
- Adrenal Tumors: If an adrenal tumor is the cause, surgical removal of the adrenal gland (adrenalectomy) may be necessary. This can often be done laparoscopically (minimally invasively).
- Ectopic ACTH-Secreting Tumors: Surgery to remove the tumor producing ACTH outside the pituitary gland is the ideal approach. Sometimes this tumor is in the lung or pancreas. If the tumor cannot be found or fully removed, medications or other therapies may be used.
-
Radiation Therapy:
- For pituitary tumors that cannot be completely removed surgically, radiation therapy may be used to shrink the tumor and reduce ACTH production. This can take several months or years to become effective.
-
Other Therapies:
- Bilateral adrenalectomy: Removal of both adrenal glands is an option to stop cortisol production completely, but requires lifelong hormone replacement.
- Novel approaches such as immunotherapy are being explored to target the underlying cause.
The specific treatment plan is tailored to each patient, considering the underlying cause of hypercortisolism, the severity of symptoms, and other individual factors. Regular monitoring and follow-up are crucial to ensure effective management and prevent complications.
