Macrolide-Induced Aldosterone Suppression as a Functional Marker of KCNJ5-Mutated Aldosterone-Producing Adenoma: A Proof-of-Concept Clinical and Experimental Study (MAPA Study).
OBJECTIVE Primary aldosteronism (PA), the most common curable form of hypertension, is frequently caused by aldosterone-producing adenomas (APAs) harboring KCNJ5 mutations that render aldosterone synthesis sensitive to macrolides in vitro. This study aimed to evaluate whether a single dose of roxithromycin reduces plas...
