The use of enteral nutrition formulas enriched with branched-chain amino acids (BCAAs) is best used for patients with which condition?

• A. Cirrhosis
• B. Refractory encephalopathy
• C. Hepatic failure
• D. Liver transplantation

Answer: (B)

BCAA-enriched enteral formulas are used to rebalance amino acids in liver disease, specifically to help hepatic encephalopathy. In this condition, aromatic amino acids build up while branched-chain amino acids are relatively reduced; increasing BCAAs can compete for transport across the blood-brain barrier and support brain function, while also aiding protein synthesis in malnourished patients. This approach is most beneficial when hepatic encephalopathy is refractory to standard treatments like lactulose or rifaximin, providing an adjunctive strategy to improve encephalopathy symptoms. Cirrhosis or hepatic failure without encephalopathy, and situations surrounding liver transplantation, do not typically require BCAA-enriched formulas as the primary management approach.
