Plasma atrial natriuretic peptide (ANP) levels were measured in non-dialyzed and dialyzed chronic renal failure (CRF) patients and in normal subjects. Changes in plasma ANP in response to hemodialysis (HD) and to isolated ultrafiltration (UF) were also investigated in dialyzed CRF patients. Plasma ANP levels were significantly higher in 28 non-dialyzed CRF patients than in 27 normal subjects (mean +/- SEM, 174.0 +/- 25.9 vs 25.0 +/- 1.9 pg/ml, p less than 0.001). Plasma ANP levels did not correlate with blood urea nitrogen or serum creatinine, however patients with advanced renal failure (creatinine clearance less than 10 ml/min) with cardiomegaly (cardiothoracic ratio greater than 50%) or hypertension (BP greater than 140/90 mmHg) had significantly higher plasma ANP levels than those who were not. A 6-hour HD significantly decreased the plasma ANP level (423.4 +/- 71.3 to 220.6 +/- 40.0 pg/ml, p less than 0.001) and body weight in 21 dialyzed CRF patients, and the decrement in plasma ANP showed a positive correlation with the decrement in body weight (r = 0.425, p = 0.056). In 8 dialyzed CRF patients, we further performed a 1-hour isolated UF for removal of isoosmotic intravascular fluid without changes in the solute concentrations, followed by a subsequent 5-hour HD. The decrease in plasma ANP during the 1-hour UF period was 68% of the total ANP decrement for the whole 6-hour study. The average plasma ANP level was decreased with 94.6 +/- 42.5 pg/ml/kg/h in the UF period compared to 3.5 +/- 1.4 pg/ml/kg/h in the HD period (p less than 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)
