1. In order to examine the potential role of endogenous atrial natriuretic peptide (ANP) in modulating the increased sodium excretion per nephron in chronic renal failure, we studied healthy subjects with normal renal function (group I) and patients with moderate (group II) or severe chronic renal failure (group III) before, during and after administration of an intravenous sodium load. All subjects had been on a controlled diet containing 120 mmol of sodium per day for 5 days before the study. 2. Under basal conditions, plasma ANP and fractional excretion of sodium (FENa) were highest in group III. Both parameters increased in response to the sodium load in the three groups studied (P < 0.001). Changes with time differed from group to group (P < 0.05), the more marked response for both parameters being observed in group III. After adjustment with respect to plasma ANP (analysis of covariance), FENa was no longer modified in response to the sodium load, whereas adjustment of FENa with respect to mean blood pressure was without consequence on the significance of its change with time. This demonstrates that plasma ANP, but not mean blood pressure, represents the main factor producing variation in FENa during and after the sodium load. 3. These results suggest an important role for plasma ANP in promoting adaptation of short-term sodium excretion in response to an acute sodium load in patients with chronic renal failure who ingest a normal sodium intake.

1. Plasma levels of immunoreactive alpha human atrial natriuretic peptide (IR-ANP) were measured in nine patients with chronic renal failure before and after removal of 1.3–3.7 litres of fluid by ultrafiltration and again during volume repletion with intravenous sodium chloride solution (150 mmol/l: saline). 2. Baseline levels of IR-ANP were elevated but fell by 22% during ultrafiltration. 3. Saline infusion induced a rapid and steep rise in IR-ANP levels which were 150% of baseline while body weight was still 2% below baseline. 4. Changes in plasma renin, angiotensin II, aldosterone and vasopressin during the study were slight compared with the change in IR-ANP, but noradrenaline levels rose threefold during ultrafiltration. 5. There was a significant positive relationship between arterial pressure and IR-ANP levels before and after ultrafiltration. 6. These results lend support to the suggestion that atrial peptides are of physiological importance, especially in states of chronic fluid overload such as chronic renal failure.
