title: Pattern of serum amino acids in patients with liver cirrhosis. Influence of shunt surgery and transesophageal sclerotherapy.
abstract: The serum amino acid pattern was studied in 30 patients with alcoholic liver cirrhosis, in 15 patients with non-alcoholic cirrhosis, and in nine healthy controls. Patients with alcoholic liver cirrhosis had significantly increased serum levels of aspartic acid, proline, methionine, tyrosine, phenylalanine, and tryptophan compared with controls. Valine was significantly decreased. Patients with non-alcoholic liver cirrhosis differed from patients with alcoholic liver cirrhosis only in having significantly greater serum levels of glycine. The serum amino acid pattern of nine cirrhotic patients who underwent mesocaval interposition shunt surgery because of bleeding esophageal varices was prospectively compared with that of nine matched patients treated with transesophageal sclerotherapy. A further significant increase in methionine and tyrosine serum levels was noted after shunt surgery. It is concluded that sclerotherapy influences serum amino acids less, which might be an advantage in relation to the development of hepatic encephalopathy.
