Abstract

<p>Liver cirrhosis is associated with impaired liver function due to various metabolic disorders, causing poor prognosis and several complications, such as hepatic encephalopathy. Although a number of studies have reported the favorable effects of branched-chain amino acid (BCAA) administration on hepatic encephalopathy, liver function, and prognosis, several studies have shown that BCAA administration might be associated with the following adverse effects: activated glutamine catabolism to ammonia and drainage of alpha-ketoglutarate from the TCA cycle. This review presents the mechanism and management of the favorable and harmful effects of BCAA administration in patients with liver cirrhosis.</p>
