BACKGROUND The haemodynamic responses to angiotensin II type 1 (AT1) receptor blockade may be mediated in part by interactions between angiotensin II and the angiotensin II type 2 receptor (AT2R). An AT2R G1675A gene polymorphism has been described, but the functional effects of this polymorphism are unknown. METHODS Haemodynamic function, circulating renin-angiotensin system mediators and no...

conclusions spironolactone combined with aceis or arbs leads to reduction of proteinuria in chronic kidney disease and therefore reduction of progression of the disease. objectives the study was designed to assess the effects of spironolactone as the aldosterone antagonist combined with acei or arb drugs to reduce proteinuria in chronic kidney disease to prevent its progression. patients and me...

A monoclonal anti-idiotypic antibody (H10E4C9F) that interacts with the aldosterone receptors was generated using an auto-anti-idiotypic approach by immunizing a mouse with a 3-O-carboxymethyloxime of aldosterone coupled to bovine serum albumin. This antibody, an IgG1, displayed internal image properties of aldosterone and was considered as an Ab2 beta according to the following criteria. (i) H...

CONTEXT Aldosterone levels increase during the luteal phase of the menstrual cycle. Prior studies examining relationships between aldosterone and female sex hormones did not control for sodium balance, a major determinant of aldosterone production. OBJECTIVES The objectives of this study were 1) to compare aldosterone levels between menstrual phases among cycling women in high- and low-sodium...

Spironolactone, a competitive aldosterone receptor antagonist (ARA), has traditionally been the treatment of first choice in idiopathic hyperaldosteronism (IHA) and for preoperative management of aldosterone producing adenoma (APA). Spironolactone is partially absorbed, is extensively metabolized mainly by the liver and its therapeutic properties are attributable to active metabolite canrenone....

Abnormal aldosterone physiology has been implicated in the pathogenesis of cardiometabolic diseases. Single aldosterone measurements capture only a limited range of aldosterone physiology. New methods of characterizing aldosterone physiology may provide a more comprehensive understanding of its relationship with cardiometabolic disease. We evaluated whether novel indices of aldosterone response...

• For many years it has been recognized that normal human subjects and normal dogs retain salt and water only transiently and fail to develop edema during the chronic administration of large doses of a sodium-retaining hormone such as desoxycorticosterone acetate ( DCA ). Similarly, some Addisonian patients retain Na for only a few days in response to prolonged administration of DCA or aldoster...

Adrenocortical tumours of the adrenal glands are formed when cells cortical layer grow. The morphological and histological structure benign is variable, which complicates their early diagnosis. study levels hormones in cortex along with analysis symptoms disease will allow not only to differentiate hormone-producing tumours, but also predict direction metabolic processes, make it possible choos...

Both clinical and experimental reports indicate that aldosterone contributes to the progression of renal failure independent of its hemodynamic effects. In the present study, we evaluated effect of aldosterone on human mesangial cell (MC) growth. Aldosterone induced apoptotic and mitogenic effects on MCs. Aldosterone promoted MC apoptosis in a dose- and time-dependent manner. Spironolactone, a ...
