  • Title: Role of aldosterone in the sodium retention of patients with nephrotic syndrome.

    Journal: Am J Nephrol; 1990; 10(1):44-8. PubMed ID: 2188506.
    Abstract:
    The role of aldosterone in the abnormal sodium retention in patients with nephrotic syndrome has been debated. In fact, studies using a converting enzyme inhibitor to lower plasma aldosterone have rejected such a role. We therefore studied 5 nephrotic patients and 6 control subjects by using the more specific aldosterone antagonist, spironolactone. After withdrawal of diuretics 5 days prior to the study, the nephrotic patients and control subjects were placed on a high-sodium diet (285 +/- 6 mEq/day) for 8 days. After 4 days, spironolactone 200 mg p.o., b.i.d., was given for the remaining 4 days. Plasma renin activity and plasma aldosterone levels were similar in both nephrotic patients and control subjects before the study, after sodium loading and after spironolactone had been given. After 4 days of high sodium intake control subjects were in sodium balance, but the nephrotic patients were in a positive sodium balance (approx. 80 mEq/day; p less than 0.01). On days 3 and 4 of spironolactone, the nephrotic patients exhibited an increase in urinary sodium excretion (205 +/- 20 vs. 312 +/- 13 mEq/day; p less than 0.005) but not the control subjects (279 +/- 16 vs. 286 +/- 13 mEq/day; NS). It is therefore concluded that aldosterone is a significant contributor to the sodium retention in patients with nephrotic syndrome.
