title: [Effects of autogenous reinfusion of ascitic fluid on plasma atrial natriuretic peptide and renin activity in cirrhotic patients].
abstract: Acute volume loading produced by autogenous reinfusion of ascitic fluid provides an ideal volume expansion model for studying hormonal regulation and it was carried out in 10 cirrhotic patients with massive ascites. The basal plasma ANP level in the cirrhotic patients with ascites was 1776.00 +/- 160.72 ng/L, which was significantly elevated as compared with the level in normal controls (378.36 +/- 39.58 ng/L, P less than 0.01), PRA was significantly higher in patients with ascites (5.13 +/- 0.18 micrograms/l/h) than in healthy volunteers (1.46 +/- 0.31 micrograms/l/h, P less than 0.01). During reinfusion of ascitic fluid there was a significant natriuresis and diuresis; ANP rose from a basal mean value to a peak value of 2166.00 +/- 195.70 ng/l (P less than 0.05) at periinfusion. Subsequently, ANP dropped at 1 hour after infusion (1819.00 +/- 165.92ng/L, P less than 0.05), PRA dropped progressively from a mean basal level to that of 2.48 +/- 0.58 micrograms/l/h (P less than 0.05) at periinfusion. These data demonstrate that there is no evidence for absolute deficiency of ANP in cirrhosis with ascites. The immediate diuresis and natriuresis were associated with a rise in ANP, but the sustained renal consequences may be possibly connected with suppression of RAAS.
