Background. The liver is the primary organ for amino acid metabolism, and metabolic disorder of amino acids is common in liver disease. However, the characteristics of plasma amino acid profiles in patients with HBV-related cirrhosis and the impacts of late-evening snack (LES) on cirrhosis are unclear. Objectives. To investigate the characteristics of plasma amino acid profiles in patients with HBV-related chronic hepatitis, cirrhosis, and the effects of late-evening snacks on plasma amino acid profiles. Methods. 86 patients with HBV-related cirrhosis and eighty patients with chronic hepatitis B were included in this study. The plasma amino acid profiles were measured by the amino acid analyzer. Patients were randomly divided into two groups, of which the liver cirrhosis group was to receive daily LES ( n = 43 ) or non-LES ( n = 43 ) for 6 months. Plasma amino acid profiles and biochemical parameters were measured in both groups at baseline and after 1, 3, and 6 months. Results. Compared to healthy controls, the plasma concentration in the liver cirrhosis group of threonine, serine, glycine, glutamine, cysteine, tyrosine, phenylalanine, arginine, and methionine increased significantly ( P < 0.05 ), while the ratio of branched chain amino acids (BCAA) to aromatic amino acids (AAA) decreased significantly ( P < 0.05 ). A carbohydrate-predominant LES treatment resulted in a significant increase in BCAA/AAA and decrease in the level of ammonia and glutamine compared with baseline after 6 months of supplementation ( P < 0.05 ). Patients with Child-Pugh B and C are more responsive to changes in amino acid profiles than those with Child-Pugh A. Conclusions. The application of an LES carbohydrate module for six months in liver cirrhosis patients was associated with increased BCAA/AAA and decreased level of ammonia. Patients with Child-Pugh B and C grades were the most beneficial population.

1., Intravenous infusions of l-valine (600 μmol/min), l-isoleucine (150 μmol/min), l-leucine (300 μmol/min) and a mixture of the three branched-chain amino acids (70% l-leucine, 20% l-valine, 10% l-isoleucine; 270 μmol/min) were given to four groups of healthy volunteer subjects. Whole-blood concentrations of amino acids and glucose and serum insulin were measured before and during the infusions. 2. Valine and isoleucine infusions resulted in twelve- and six-fold increases in the respective amino acid. During valine infusion, tyrosine was the only amino acid for which a decrease in concentration was seen (25%, P < 0.05). With isoleucine administration, no significant changes were found. In contrast, leucine infusion (during which the leucine concentration rose about sixfold) was accompanied by significant decreases in tyrosine (35%), phenylalanine (35%), methionine (50%), valine (40%) and isoleucine (55%). The arterial glucose concentration fell slightly (5%) and the insulin concentration increased 20% during leucine infusion. 3. Infusion of the mixture of the three branched-chain amino acids resulted in marked decreases in tyrosine (50%), phenylalanine (50%) and methionine (35%). The decreased amino acid levels remained low for 2 h after the end of the infusion. 4. The present findings demonstrate that intravenous infusion of leucine (not infusion of valine or isoleucine) results in marked reductions in the concentrations of the aromatic amino acids and methionine. Infusion of a mixture of the three branched-chain amino acids gives results similar to those obtained with leucine infusion alone. Thus a mixed branched-chain amino acid solution with leucine as its main constituent seems to be the best alternative in the treatment of patients with hepatic cirrhosis and encephalopathy.

Changes in plasma amino acid concentrations were measured in patients with hepatic failure during extracorporeal hemodiabsorption (using the Liver Dialysis Unit, “the Unit”) or hemodiabsorption plus sorbent-based pheresis treatment (using the Liver Dialysis Plasmafilter Unit, “the PF-Unit”) Systems. Eight patients with hepatic failure, grade 3 or 4 encephalopathy, elevated bilirubin and/or creatinine levels and respiratory or renal failure were treated for 1–3 days with the Unit alone. Three of these were also treated with the Unit containing 10 g of BCAA in the sorbent suspension. Four patients with hepatic failure treated with the PF Unit also had 10 g of branched chain amino acid (BCAA) added to the sorbents of the Unit portion of this device. Pre- and post-plasma samples were drawn and high performance liquid chromatography (HPLC) was used to separate and detect amino acids in the plasma. Both the Unit and the PF-Unit have the capability to selectively remove various amino acids, especially aromatic amino acids (AAA). The pre-treatment amino acid profiles of plasma were typical for hepatic failure, with abnormally high levels of phenylalanine, tyrosine, tryptophan, and methionine and decreased levels of valine, leucine and isolucine. The average pre-treatment Fischer ratio (BCAA/AAA) for both Unit and PF-Unit patients was 1.43 (±0.58). Treatments by both systems resulted in an increase of BCAA levels in blood and concomitant decrease of AAA levels, with an average Fischer ratio improvement of 30–38% for the Unit and PF-Unit without BCAA. The Fischer ratio improved by 90% (average) for the Unit with BCAA. Levels of many other amino acids (such as alanine, glycine, proline or lysine) increased during both Unit and PF-Unit treatments. The removal of strongly protein-bound toxin and amino acids such as tryptophan and sulphydryl amino acids was more effective by the PF-Unit. Both the Unit and the PF-Unit have the unique capability to remove toxic aromatic amino acids while increasing BCAA levels in patient. The increase in many amino acid levels may be related to the removal of toxins that interfere with normal amino acid metabolism. The addition of the PF module improves the removal of bilirubin and similarly protein-bound chemicals. Changes in amino acid profiles by the Unit and the PF-Unit contrast markedly with other extracorporeal devices.

In cirrhotic patients, plasma amino acid levels are severely deranged. A decreased ratio of branched-chain to aromatic amino acids (Fischer ratio) has been implicated in the pathogenesis of hepatic encephalopathy. In this prospective study, we investigated the effects of extracorporeal detoxification on amino acid levels using a sorbent suspension dialysis system. Twenty patients with documented cirrhosis and hepatic encephalopathy grade II-III not responding to standard treatment were randomized to receive either six hours of sorbent dialysis and standardized conventional medical treatment or ongoing medical treatment alone. In contrast to previous uncontrolled studies, no significant effect on amino acid levels, Fischer ratio or clinical grade of hepatic encephalopathy was detected in either treatment group. In conclusion, a 6-hour treatment with sorbent dialysis did not significantly influence plasma levels of amino acids and did not ameliorate the clinical grade of hepatic encephalopathy.
