title: Effects of atrial natriuretic peptide in clinical acute renal failure.
abstract: Fifty-three consenting patients meeting clinical and urine composition criteria for established intrinsic ARF were assigned to two treatment groups. Group I patients were treated with human atrial natriuretic peptide (ANP) with or without diuretics. Groups II patients were treated with or without diuretics and with no ANP. Age, sex, etiology of ARF, entry serum creatinines (SCr) (Group I, 5.3 +/- 1.8; Group II, 5.1 +/- 2.1 mg/dl) and creatinine clearances (CCr) (Group I, 9.9 +/- 2.1; Group II, 9.2 +/- 2.1 ml/min) were similar. Thirty patients received ANP [0.20 micrograms/kg/min i.v. x 24 hr (N = 20) or 0.08 micrograms/kg/min i.a. x 8 hr (N = 10)] and furosemide, 0.5 mg/kg/hr x 24 hr or mannitol, 12.5 g every six hours x 4, or no diuretic; 23 Group II patients received diuretics as above or no diuretic in a similar distribution to Group I. CCr (verified with simultaneous inulin clearances x 12, r = 0.93, P < 0.001) increased significantly by eight hours of ANP treatment to 17.1 +/- 3.2 ml/min and by 24 hours after discontinuing ANP to 21.0 +/- 4.4 ml/min (both P < 0.05). There was no corresponding increase in CCr in Group II. Dialysis was required in 23% of Group I and in 52% of Group II patients (different at P < 0.05). Mortality rates of 17% for Group I and 35% for Group II were not significantly different (P = 0.11). It is concluded that parenteral ANP increases CCr and reduces need for dialysis in patients with established intrinsic ARF.
