Measuring circulating androgen and gestagen concentrations is essential for the diagnosis and treatment monitoring of pathological conditions caused by abnormal steroidogenesis, such as congenital adrenal hyperplasia (CAH) and polycystic ovary syndrome (PCOS). Saliva collection represents a simple and non-invasive technique advantageous for multi sample profiling. We therefore developed a liquid chromatography-tandem mass spectrometry assay for the s...

BackgroundStandard glucocorticoid (GC) therapy in classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21-OHD-CAH) is often inadequate in controlling adrenal androgen excess, leading to GC over-exposure and poor health outcomes. A novel modified-release formulation of hydrocortisone (MR-HC, Chronocort® Diurnal Ltd. UK) has been shown to improve circulating adrenal androgen excess in 21-OHD-CAH. We investigated whether saliva and ...

Background: The gonads are the major source of classic androgens during reproductive years. Additionally, the adrenal gland produces precursors for both classic and 11-oxygenated androgen biosynthesis, with androgen activation predominantly occurring in peripheral target tissues of androgen action. We used liquid chromatography-tandem mass spectrometry to profile classic and 11-oxygenated androgens in serum and saliva across the adult age range and assessed diurnal as well as ...
