Summary

Hyperaldosteronism type III (HALD3) is characterized by hypertension secondary to massive adrenal mineralocorticoid production. Like patients with glucocorticoid-remediable aldosteronism (GRA, or HALD1; 103900), patients with HALD3 present with childhood hypertension, elevated aldosteronism levels, and high levels of the hybrid steroids 18-oxocortisol and 18-hydroxycortisol. However, hypertension and aldosteronism in HALD3 are not reversed by administration of exogenous glucocorticoids and patients require adrenalectomy to control hypertension (Geller et al., 2008).
