Correlation Between Coagulation Index and Hormone Levels in Patients with ACTH-Independent Cushing's Syndrome

Abstract:
The aim of the study was to explore the relationship between hormone levels and coagulation indicators in patients with Cushing's syndrome, providing insights into disease progression and treatment. We recruited 640 patients diagnosed with ACTH-independent Cushing's syndrome with adrenocortical tumors, conducting comprehensive physical and laboratory examinations, and analyzing data using logistic regression models. We found that compound F at 8 AM (F8AM) and ACTH had better correlation with coagulation characteristics. We revealed negative association between F8AM levels and PLT or APTT, while ACTH exhibited opposite trends. With F8AM increasing, Fbg declined significantly, while ACTH had the opposite association. In patients with Cushing's syndrome, chronic cortisol elevations may lead to consumptive coagulopathy, characterized by decreased PLT and Fbg levels, apart from the hypercoagulable state implied by decreased APTT.

Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Hormones of the Adrenal Glands
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...

Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
