I can provide information about Cushing’s disease, but the search results do not contain specific details on how often horses with Cushing’s disease should be monitored.
Cushing syndrome results from high levels of cortisol in the body. Diagnosing Cushing syndrome involves measuring cortisol levels in serum, saliva, or urine. Doctors differentiate the causes of Cushing syndrome by measuring serum ACTH and serum cortisol concentrations before and after administering dexamethasone.
Treatment depends on the specific cause, and many symptoms disappear once the cause of excess cortisol is removed. Pituitary tumors can be surgically removed, and radiation therapy can be used if surgery isn’t an option. Adrenal tumors can also be surgically removed, often curing benign tumors. Drugs like ketoconazole and mitotane can reduce cortisol secretion and slow tumor growth in patients with adrenal cancer.
