The metabolism of sulphur-containing amino acids is impaired in patients with advanced liver disease, but very few data are available in less severe chronic liver disease. We measured fasting plasma levels of methionine, cystine and taurine in 10 healthy subjects and 50 patients with biopsy proven liver disease: chronic persistent/active hepatitis (30 cases), compensated cirrhosis (10 cases) and decompensated cirrhosis (10 cases). Hypermethioninemia (up to 10 times control values) was present only in decompensated cirrhosis. This study suggests that a derangement in sulphur amino acid metabolism, possibly located at various steps along the trans-sulphuration pathway, is also present in mild forms of chronic liver disease.

Abstract
The metabolism of sulphur-containing amino acids is impaired in patients with advanced liver disease, but very few data are available in less severe chronic liver disease. We measured fasting plasma levels of methionine, cystine and taurine in 10 healthy subjects and 50 patients with biopsy proven liver disease: chronic persistent/active hepatitis (30 cases), compensated cirrhosis (10 cases) and decompensated cirrhosis (10 cases). Hypermethioninemia (up to 10 times control values) was present only in decompensated cirrhosis. This study suggests that a derangement in sulphur amino acid metabolism, possibly located at various steps along the trans-sulphuration pathway, is also present in mild forms of chronic liver disease.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
