Abstract:
Objective To analyze the patterns of amino acid changes in liver failure patients treated with non-bioartificial liver support system (ALSS), and to explore the efficacy of ALSS in liver failure treatment. Methods A total of 146 liver failure patients treated with ALSS from June 2009 to August 2010 were recruited in this study. Paired blood samples were collected from every patient and serum amino acids and ammonia were tested by automatic amino acid analyzer. The changes of amino acids in patients with different prognoses, different types/phases of liver failure were evaluated.Measurement data were compared by paired t test. Results After ALSS treatment, liver failure patients experienced a significant decrease in serum glutamic acid and lysine [(395.62±200.24)μmol/Lvs (260. 05±169.56) μmol/L and (436. 73±326. 18)μmol/L vs (407. 12±292.01) μmol/L,respectively; t= 8. 611 and 2. 659, respectively; both P＜0.01)], while experienced greatly increases in threonine and branched-chain amino acids/aromatic amino acid ratio [( 1302. 90 ±1288.70) μmol/L vs (1406.70 ±1272. 34) μmol/L and 1. 23 ± 0. 53 vs 1. 36 ± 0.57, respectively; t = 2. 895 and 1. 061,respectively; both P＜0. 01)]. The changes of glutamic acid, tyrosine, arginine and methionine before and after ALSS treatment in patients with different prognoses, different types/phases of liver failure were all significantly different. Conclusions ALSS treatment could improve the serum amino acid disorder in liver failure patients. The amino acids in patients with different types/phases or different prognoses of liver failure change significantly after ALSS treatment.
