The role of aldosterone has expanded from the hormone's genomic effects that involve renal sodium transport to nongenomic effects that are independent of the effect of aldosterone on sodium transport. The nongenomic effects of aldosterone to increase fibrosis, collagen deposition, inflammation, and remodeling of the heart and blood vessels, however, are markedly increased in the presence of hig...

Observations were made on the relation of the renin-angiotensin-aldosterone system and renal hemodynamic function to sodium balance in 43 pregnant dogs. Daily balance studies revealed that about 30-40% of ingested sodium was retained during the last half of pregnancy; during the same period, potassium balance was also positive but to a lesser extent. For groups of pregnant dogs, plasma renin ac...

JRAAS 2001;2:211-14 The traditional view is that angiotensin II (Ang II) is the principal culprit in the renin-angiotensinaldosterone system (RAAS). However, it is now appreciated that aldosterone is a second culprit and that the harmful effects of aldosterone are additional to those of Ang II. The relative importance of Ang II and aldosterone can be illustrated by the fact that during chronic ...

The renin-angiotensin aldosterone system is a critical mechanism for controlling blood pressure, and exerts most of its physiological effects through the action of angiotensin II. In addition to increasing blood pressure by increasing vascular resistance, angiotensin II also stimulates aldosterone secretion from the adrenal gland. Aldosterone acts to cause an increase in sodium and water reabso...

Chronic ACTH excess leads to chronic cortisol excess, without escape phenomenon, resulting in Cushing's syndrome. Excess adrenal androgens also occur: in females, they will overcompensate the gonadotrophic loss, inducing high testosterone; in males, they will not compensate it, inducing low testosterone. Chronic ACTH excess leads to chronic adrenal mineralocorticoid excess and low aldosterone l...

Effects of Endothelin Receptor Antagonism Relate to the Degree of Renin-Angiotensin System Blockade in Chronic Proteinuric Kidney Disease To the Editor: We thank Benigni and Remuzzi1 for their informative editorial relating to our study.2 They raise a number of pertinent issues. They comment that it would be interesting to know whether subjects included with focal segmental glomerulosclerosis (...

AIMS The purpose of this study was to examine, in chronically treated heart failure patients vs control subjects, the influence of neurohumoral activation and aldosterone escape on arterial elastic behaviour, assessed by non-invasive mathematical lumped-parameter modelling of the compliance of the arterial system. METHODS AND RESULTS Radial arterial pulse waves were recorded non-invasively fo...

Aldosterone production occurs in the adrenal cortex, and is regulated primarily by angiotensin II (Ang II), potassium and adrenocorticotropin (ACTH). In the presence of the aldosterone stimulators, steroidogenesis is further governed by local autocrine and/or paracrine factors in the adrenal cortex. We reported the presence of functional bone morphogenetic protein (BMP) system in the adrenal co...
