Abstract
Eight outpatients with advanced hepatic cirrhosis were tested over 3
months for branched-chain amino acids (BCAA) supplements in the late
evening. Serum albumin level (2.8±0.3 vs. 3.1±0.2 g/dl, P<0.002),
serum cholin esterase activity (54±13 vs. 67±17 IU/l, P<0.02), and
plasma Fischer's ratio (1.3±0.9 vs. 1.4±0.9, P<0.005) increased over
the 3 months. The frequency of muscle cramps decreased (7.4±2.0 vs.
0.3±0.5 times/week, P<0.0001) dramatically. These data suggest that
BCAA supplements in the late evening are of benefit to malnourished
patients with hepatic cirrhosis. Relief of muscle cramping is an
important outcome of BCAA supplements in the late evening.
