Background: Current guidelines recommend adrenal vein sampling (AVS) for the identification of surgically treatable unilateral disease among patients with primary aldosteronism (PA). The cortisol-derived selectivity index (SI) is currently used to assess the success (or selectivity) of adrenal vein catheterization during AVS. However, AVS studies can be non-selective in many cases.Aim: To examine whether the use of SI derived either from 11-deoxycortisol...

Background: Confirmation of primary aldosteronism (PA) with the saline infusion test (SIT) requires accurate measurements of plasma aldosterone, best achieved by mass spectrometry. Performance of the test and appropriate cut-offs remain inadequately defined.Design and methods: This prospective multicenter cohort study involved 451 patients with suspected PA who underwent a seated SIT. Among these, there were 90 and 76 in whom PA was respectively confirmed and excluded based on...

False-positive and false-negative results during screening, confirmatory testing and subtyping for suspected primary aldosteronism: lessons from Prosaldo

Background: Diagnostic stratification of patients with suspected primary aldosteronism (PA) is a multistep process reliant on tests that are not infallible. Only through prospective studies can diagnostic accuracy be appropriately assessed.Methods: The PROSALDO trial enrolled 819 patients between 2019 and 2023 to assess steroid profiles against routine tests for diagnostic stratification. A combination of these tests and outcome assessments, including me...
