Plasma levels of atrial natriuretic peptide in patients with chronic liver disease.
The plasma levels of atrial natriuretic peptide were determined by radioimmunoassay in 24 patients with chronic liver disease, including three patients with alcoholic liver disease, four with chronic active hepatitis, 13 with liver cirrhosis, and four with hepatocellular carcinoma. When compared with normal subjects (180 +/- 12 pg/ml), the plasma levels of atrial natriuretic peptide in cirrhotic patients (349 +/- 64 pg/ml) were significantly elevated (p less than 0.001) but not in other disease groups. In patients with chronic liver disease the plasma levels of atrial natriuretic peptide were correlated significantly with plasma renin activity but not with plasma aldosterone, and furthermore showed a negative correlation with indocyanine green disappearance rate. These results suggest that the increased plasma levels of atrial natriuretic peptide, which appear to be associated with an increase in plasma renin activity and with hepatic dysfunction, may participate in maintaining homeostasis of sodium and fluid volume in patients with chronic liver disease.
