Effect of acute sodium or potassium depletion on plasma renin activity in haemodialysed patients. 1976

T Drüeke, and D Pasques, and N Koa Man, and J P Grünfeld

A closed loop closed batch dialysate delivery system was used to determine whether Na or K has an action on the renin-angiotensin system apart from volume changes. Twenty-eight patients on chronic haemodialysis were studied, 12 (group I) were normotensive and 16 (group II) had poorly controlled hypertension. Acute Na depletion or repletion (delta NA), AND K loss (delta K) were induced with or without net water loss. Net electrolyte and water movement across the dialysis membrane could be precisely quantitated.

UI MeSH Term Description Entries
D006973 Hypertension Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more. Blood Pressure, High,Blood Pressures, High,High Blood Pressure,High Blood Pressures
D008297 Male Males
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D011188 Potassium An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
D012083 Renin A highly specific (Leu-Leu) endopeptidase that generates ANGIOTENSIN I from its precursor ANGIOTENSINOGEN, leading to a cascade of reactions which elevate BLOOD PRESSURE and increase sodium retention by the kidney in the RENIN-ANGIOTENSIN SYSTEM. The enzyme was formerly listed as EC 3.4.99.19.
