Plasma angiotensin II, renin, renin-substrate and aldosterone concentrations in acute renal failure in man.
Plasma concentrations of angiotensin II, renin, renin-substrate and aldosterone were measured in cases of acute renal failure. Angiotensin II, and renin levels were abnormally high on at least one occasion in nearly all patients. Mean angiotensin II and renin levels were highest in the first ten days of the disease. There was a highly significant positive correlation between concurrent estimations of renin and angiotensin II. Renin-substrate was also frequently elevated, but the correlations with renin and angiotensin II were not statistically significant. Despite the frequently marked elevation of plasma angiotensin II, only 2 of 17 measurements of plasma aldosterone were abnormally high. There was no significant relationship between aldosterone and plasma concentrations of angiotensin II, renin, sodium or potassium. The data are discussed in relation to current hypotheses implicating renin and angiotensin in the pathogenesis of acute circulatory renal failure.
