Background: Primary aldosteronism (PA) is mainly caused by unilateral (unilateral PA) or bilateral aldosterone-producing lesions of adrenals (bilateral PA). Accumulating findings suggest distinct metabolic profiles between patients with unilateral and bilateral PA. However, the link between the metabolic features and histopathologic findings of adrenals from patients with PA remains largely unknown.Objective: To characterize metabolic profiles with a foc...

Context: Cytochrome P450 (CYP) 17A1 is located at major branch points of steroidogenesis exerting two distinct catalytic activities: 17α-hydroxylase generates glucocorticoid precursors and 17,20-lyase generates the principal sex steroid precursor dehydroepiandrosterone (DHEA). CYP17A1 deficiency (17OHD) is a rare form of congenital adrenal hyperplasia. In severe 17OHD, affected individuals typically present with both glucocorticoid and sex steroid deficiency and mineraloc...
