title: Extracellular volume and aldosterone interaction in chronic kidney disease.
abstract: Since the advent of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, little attention has been given to the potential proinflammatory effects of aldosterone in high-volume states on the kidney and cardiovascular system. In order to be correctly interpreted, aldosterone levels require a volume cofactor which can now be determined by measurement of extracellular fluid volume by means of bioimpedance. Chronic kidney disease patients frequently have expanded extracellular volume (ECV) in the presence of elevated aldosterone levels. This combination may lead to cardiovascular and renal inflammation and fibrosis that can be mitigated by more precise control of ECV and/or blockade of the mineralocorticoid receptor.
