Administration of branched-chain amino acids (BCAA) has been reported to improve liver function, quality of life (QOL). However, in some malnourished patients, serum albumin levels do not improve in response to BCAA granules. In this study, we examined the effects of BCAA-enriched enteral nutrition in patients unresponsive to BCAA granules. Thirty-two decompensated cirrhotic patients at Osaka Medical College were enrolled in this study. Since all patients showed no improvement in serum albumin levels despite 3 months of BCAA granule administration, they were administered 50 g of a flavored BCAA-enriched enteral nutrient twice daily, i.e., during the daytime and late evening. Serum albumin levels and major cirrhotic symptoms were examined 1, 3, and 5 months after treatment initiation. Serum albumin levels improved significantly 3 months after treatment initiation (3.14 ± 0.32 g/dl vs 3.5 ± 0.31 g/dl, p<0.01), and Child–Pugh scores decreased significantly (p<0.01). In the majority (53–80%) of patients, muscles cramps, fatigue, fatigability, edema, and sleep disturbance improved within 3 months after therapy initiation. Moreover, approximately 90% of the patients became symptom-free 5 months after treatment initiation. These results indicate that switching to BCAA-enriched nutrients improves QOL of cirrhotic patients unresponsive to BCAA granules.
