[Aldosteroneia in acute kidney failure].

In 19 patients with acute renal insufficiency the plasma renin activity (PRA) and the aldosteronaemia were determined during the phase of anuria and oliguria. Significantly elevated PRA values were found while plasma aldosterone was only moderately elevated in the blood plasma. Apart from this a significantly negative correlation between the aldosterone level and the sodium and bicarbonate concentrations in the blood plasma were found. The lack of a significant positive correlation between PRA and plasma aldosterone levels suggests the participation of factors other than renin in the regulation of the aldosterone secretion in patients with acute renal insufficiency.
