Metyrapone single administration, as a possible predictive tool of its dosage and timing in Cushing's syndrome.

Metyrapone is commonly used in the initial management of Cushing's syndrome to reduce hypercortisolemia, but its optimal dosage and timing can vary significantly between patients. Currently, there are limited guidelines on adjustment methods for its administration to individual needs. This study aimed to evaluate responsiveness of each patient to metyrapone and identify the patient characteristics associated with the indices of cortisol responsiveness following a low-dose metyrapone.

Cardiovascular Disease [CVD], the leading cause of death globally, poses a significant burden on the healthcare sector. Its association with stress and Cushing's Syndrome has driven cortisol, the 'stress hormone,' to be a potential candidate in determining CVD risk. Cortisol synthesis and release through the hypothalamic-pituitary-adrenal [HPA] axis are regulated by several hormones and receptors involved in the pathological cascade towards CVD.

The long-term hypercortisolemia of Cushing disease (CD) may lead to hemodynamic disorders by increasing subclinical cardiac and vascular dysfunction. The purpose of this observational cohort study was to assess the relationship between hemodynamic parameters evaluated via impedance cardiography (ICG) and echocardiographic parameters reflecting left ventricular function in 54 patients newly diagnosed with CD. The parameters assessed via ICG included stroke volume index (SI), cardiac index (CI), acceleration index (ACI), velocity index (VI), systemic vascular resistance index (SVRI), total artery compliance index (TACI).

Context: Little is known about presenting clinical characteristics, tumor biology, and surgical morbidity of Cushing's disease (CD) with aging.
Objective: Using a large multi-institutional dataset, we assessed diagnostic and prognostic significance of age in CD through differences in presentation, laboratory results, tumor characteristics, and postoperative outcomes.
Design: Data from the Registry of Adenomas of the Pituitary and Related Disorders (RAPID) were reviewed for patients with CD treated with transsphenoidal tumor resection at 11 centers between 2003 and 2023.

Article Synopsis
- Non-neoplastic hypercortisolaemia, or pseudo-Cushing's syndrome (PCS), can occur due to various health conditions like depression, obesity, and diabetes, linked to overactivity of the hypothalamic-pituitary-adrenal axis.
- A 66-year-old woman exhibited symptoms such as weakness, weight loss, and poorly controlled hypertension, which led to the discovery of pheochromocytoma, a tumor that causes hormone overproduction, upon further testing.
- After undergoing surgery to remove the tumor and receiving supportive treatment, her symptoms improved significantly, confirming the diagnosis of PCS rather than traditional Cushing's syndrome.
