Introduction: 11-ketotestosterone (11KT) and 11β-hydroxyandrostenedione (11OHA4) are new biomarkers for hyperandrogenic disorders. Steroids can be measured in saliva, allowing non-invasive sampling by patients. We modified a published LC-MS/MS method1 for quantification of 11-oxygenated androgens in saliva with respect to sample volume, extraction procedure and equipment, and assessed the potential impact of different sampling devices on results.<p class="a...

Background: Primary bilateral macronodular adrenocortical hyperplasia (PBMAH) is a rare cause of ACTH-independent Cushing’s syndrome. The clinical application of adrenal venous sampling (AVS) in diagnostic work-up for PBMAH is still controversially discussed. AVS might be useful in evaluating the predominant side and guiding the decision for unilateral adrenalectomy in PBMAH.Objectives: Our aim was to evaluate whether certain metabolites in AVS samp...

Background: It is known that excessive dietary sodium intake increases cardiovascular risks and contributes to elevated blood pressure. Additionally, a high-salt diet is linked to unfavorable inflammatory immune responses. Notably, individuals with primary aldosteronism (PA) commonly exhibit elevated sodium intake. Despite treatment with mineralocorticoid receptor antagonists (MRA), PA patients do not experience a complete reduction in excess cardiovascular risk compared to hy...
