Mineralocorticoid replacement therapy in salt‐wasting congenital adrenal hyperplasia

Abstract

AbstractPatients with salt‐wasting congenital adrenal hyperplasia (SW‐CAH) usually show pronounced impairment of aldosterone secretion and, therefore, also require mineralocorticoid replacement. While a lot of research and discussion focusses on the glucocorticoid therapy in SW‐CAH to replace the missing cortisol and to control adrenal androgen excess, very little research is dealing with mineralocorticoid replacement. However, recent data demonstrated an increased cardiovascular risk in adult CAH patients urging to reflect also on the current mineralocorticoid replacement therapy. In this review, we explain the role and function of the mineralocorticoid receptor, its ligands and inhibitors and its relevance for the therapy of patients with SW‐CAH. We performed an extensive literature search and present data on mineralocorticoid therapy in SW‐CAH patients as well as clinical advice how to monitor and optimise mineralocorticoid replacement therapy.
