Osilodrostat as an emergency alternative for hypercortisolism in a patient with an impaired liver function. A case presents a 34 year old woman with an active Cushing Disease, who underwent non-radical surgery of invasive pituitary adenoma in 2014 and CyberKnife radiotherapy in 2018. Patient demonstrates many complications of long lasting hypercortisolemia- poorly controlled diabetes mellitus, heart failure, hypertension, hypercholesterolemia, mental disturbances and severe hepatic impairment. Challenges in this case are aggravated by very difficult compliance. Due to elevated liver function tests, the patient couldn’t have started ketoconazole and relacorilant treatment. Because of non-controlled DM, pasireotide treatment was contraindicated in her case. She didn’t agree either for metyrapone treatment or for adrenalectomy. Finally osilodrostat has been implemented as the last-chance alternative given at the time of severe hepatic impairment. At the dose of 2x2mg we observe clinical improvement, normalisation of UFC, decrease of Hba1c and spectacular improvement of liver function. However the current data on use of osilodrostat in patients with hepatic impairment are limited, our case shows that osilodrostat can be an emergency alternative for severe hypercortisolism with impaired liver function. The mechanism of improvement of liver function may be indirect through decreasing the level of hypercortisolemia, however potential direct beneficial influence of osilodrostat on liver function seems to be an interesting subject worth further investigation. More studies on the link between hypercortisolemia, liver function and steroidogenesis inhibitors are needed. Presentation: Thursday, June 15, 2023
