Study Notes
Therapeutic options for Cushing's Syndrome
- Pituitary irradiation can improve symptoms in 50% of patients, but it can take 6-12 months to see improvement and can cause pituitary-dependent hormone deficiencies.
- Steroidogenic inhibitors like metyrapone, aminoglutethimide, and ketoconazole can inhibit cortisol synthesis, but they can cause side effects like hypertension, sedation, and liver enzyme elevation.
- Combination therapy with metyrapone and aminoglutethimide is more effective than either agent alone and has fewer side effects.
- Etomidate is similar to ketoconazole but is only available in a parenteral formulation, making it useful for acute hypercortisolemia awaiting surgery.
- Mitotane can inhibit the production of cortisol and corticosterone, but it can cause side effects like nausea, diarrhea, and CNS effects.
- Cyproheptadine is a serotonergic antagonist that can decrease ACTH secretion, but it should be reserved for non-surgical candidates who fail more conventional therapy.
- Tretinoin can reduce ACTH secretion, but its efficacy in humans is undetermined.
- Other neuromodulatory agents include bromocriptine, cabergoline, valproic acid, octreotide, and rosiglitazone.
- Mifepristone is a receptor antagonist that inhibits dexamethasone suppression and increases endogenous cortisol and ACTH values in normal subjects.
- Limited experience in Cushing's syndrome suggests that mifepristone is highly effective in reversing the manifestations of hypercortisolism.
- None of the neuromodulatory agents has demonstrated consistent clinical efficacy for treating Cushing's syndrome.
- Combination therapy with these agents may prove more efficacious than any single agent.
