    Abstract:
    The diuretic and natriuretic responses to exogenous synthetic atrial natriuretic peptide (ANP) were evaluated in patients with chronic renal failure (CRF) or nephrotic syndrome (NS). Patients were studied after an oral water load (8 ml/kg in CRF and 20 ml/kg in NS patients). A short intravenous bolus of either a placebo or ANP was administered when urine output was stable. In each group of patients, three doses of ANP were injected at 24 h intervals, i.e., 1.0, 1.5, and 2.0 micrograms/kg in the CRF and 1.0, 1.5, and 3.0 micrograms/kg in the NS group. Blood pressure and heart rate were monitored throughout the study and urinary volume and electrolyte excretion were measured every 20 min up to 3 h after the bolus. An acute and transient fall in blood pressure was observed immediately after the ANP injection. It was more pronounced in CRF than in NS patients. In CRF patients, ANP caused only a slight increase in urinary volume (13.5-44% over baseline) but a significant increase in urinary sodium excretion (45-114% over baseline). In NS patients, significant increases in both urine volume (60-105%) and sodium excretion (149-248%) were also found. In these latter patients, the renal response to ANP appeared to be better preserved. The hemodynamic and renal changes induced by ANP occurred mainly during the first 20 min following the ANP administration, when the peak plasma ANP levels were obtained. However, no clear dose-response effect could be evidenced in either group with the three doses of ANP chosen in this study.
