The mineralocorticoid aldosterone increases in plasma in healthy pregnancy along with renin and angiotensin II and plays a key role in the physiological plasma volume expansion. • The MR is unique, being the receptor for two physiologic ligands: aldosterone and cortisol. Etude des variations de l'aldostéronurie sous l'effet de surcharges en potassium et de déperditions rénales et extrarenales de sel et d'eau. Primary outcomes were placental weight and birth weight. Aldosterone: observations on the regulation of sodium and potassium balance.

Conversely, hypokalemia inhibits aldosterone production. doi: 10.1016/j.jash.2016.10.001. Urinary aldosterone excretion at gestational week 29 independently contributed to placental and birth weights (adjusted β-coefficients [95% CI], 24.50 [9.66-39.35] and 9.59 [4.57-14.61], respectively). doi: 10.1002/14651858.CD011202.pub2.Nutrients. Predictive values of aldosterone levels and sodium and potassium intakes were assessed by multiple and Cox regression analyses. Small changes in plasma potassium have a greater effect on aldosterone than on renin secretion. Name must be less than 100 characters Clipboard, Search History, and several other advanced features are temporarily unavailable. By blocking the binding of aldosterone to its receptor, the amount of water and sodium excreted by the kidneys is increased, and potassium is retained. 1982 Dec 4;112(49):1764-74.Am J Physiol Regul Integr Comp Physiol. Salt intake >6 g/d was associated with development of preeclampsia (hazard ratio [95% CI], 5.68 [1.51-21.36]). Unable to load your delegates due to an errorBeretta-Piccoli C, Weidmann P, de Châtel R, Hirsch D, Reubi FC.Circulation. In mice, aldosterone contributes to an optimal fetal development by enhancing PlGF (placental growth factor) expression an … Aldosterone inhibitors block the function of aldosterone by binding to the aldosterone receptor, which means that the receptor is not available to bind aldosterone. Secondary outcome was preeclampsia. Ann Intern Med. Aldosterone influences electrolyte metabolism by facilitating the reabsorption of sodium ions at the distal tubules, also at the expense of hydrogen and potassium excretion. Hironobu Umakoshi Department of Medicine and Bioregulatory Science, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan. Please enable it to take advantage of the complete set of features!

Please enable it to take advantage of the complete set of features! Plasma and urinary aldosterone were measured by ELISA, sodium and potassium excretions by flame photometer. Aldosterone levels were not associated to preeclampsia incidence. Epub 2015 Apr 13.Nielsen LH, Ovesen P, Hansen MR, Brantlov S, Jespersen B, Bie P, Jensen BL.J Am Soc Hypertens.

2014 Jan 1;306(1):R61-6. Role of Aldosterone and Potassium Levels in Sparing Confirmatory Tests in Primary Aldosteronism.

doi: 10.1161/HYPERTENSIONAHA.119.12924. The greater effect of thiazides on renin activity and the greater effect of spironolactone on aldosterone production may be related to the thiazide induced reduction of serum potassium and the spironolactone induced increases of serum potassium. 2017 Feb;36(1):77-83. doi: 10.1080/10641955.2016.1239734.

In contrast, increases of plasma potassium directly stimulate aldosterone secretion. Epub 2013 Nov 20. Alterations in plasma potassium concentration have opposite and independent effects on renin secretion by the kidney and on aldosterone secretion by the adrenal gland. 2015 Jun;65(6):1316-23. doi: 10.1161/HYPERTENSIONAHA.115.05267. Verdonk K, Saleh L, Lankhorst S, Smilde JE, van Ingen MM, Garrelds IM, Friesema EC, Russcher H, van den Meiracker AH, Visser W, Danser AH.Hypertension. In patients with essential hypertension, diuretic induced alterations in serum potassium concentrations may affect both renin and aldosterone secretion. Unable to load your collection due to an error The renin-aldosterone system contributes to the regulation of arterial pressure and to the maintenance of sodium and potassium balance. This abnormality is caused by hyperplasia or tumors.Many suffer from fatigue, potassium deficiency and high blood pressure which may cause poor vision, confusion or headaches. Unable to load your collection due to an error In mice, aldosterone contributes to an optimal fetal development by enhancing PlGF (placental growth factor) expression and trophoblast cell proliferation.
