Review Meta AnalysisOral branched-chain amino acids have a beneficial effect on manifestations of hepatic encephalopathy in a systematic review with meta-analyses of randomized controlled trials.
Supplements with branched-chain amino acid (BCAA) have cerebral, metabolic, and nutritional effects that may benefit patients with hepatic encephalopathy (HE). We therefore conducted a systematic review on the effects of oral BCAAs compared with control supplements or placebo for patients with cirrhosis and recurrent overt or minimal HE. The quantitative analyses included data from 8 trials (n = 382 patients). ⋯ Subgroup, sensitivity, regression, and sequential analyses found no other sources of heterogeneity or bias. BCAA supplements had no effect on mortality or markers of nutritional status and did not induce adverse events. In conclusion, oral BCAA supplements improve manifestations of HE but have no effect on survival.
