Abstract: | Liver cirrhosis is commonly associated with nutritional alterations, reported in 20% of patients with compensated disease and over 60% of patients with decompensated cirrhosis. Nutritional disturbances are associated with a worse prognosis and increased risk of complication. Serum levels of branched-chain amino acids (BCAAs) are decreased in patients with liver cirrhosis. The imbalance of amino acids levels has been suggested to be associated with the development of complications, such as hepatic encephalopathy and sarcopenia, and to affect the clinical presentation and prognosis of these patients. Several studies investigated the efficacy of BCAAs supplementation as a therapeutic option in liver cirrhosis, but uncertainties remain about the real efficacy, the best route of administration, and dosage. |
