Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
* To investigate the plasma free amino acids relation to the nutritional state of patients with liver cirrhosis and hepatic encephalopathy.
* To determine the effectiveness, cost, cost-benefit and in-hospital prognosis of branched chain amino acid (BCAA) infusion as an adjuvant to conventional mainstay therapy in the treatment of hepatic encephalopathy due to liver cirrhosis.
* To determine the effectiveness of branched chain amino acid (BCAA) infusion on improving amino acid imbalance and Fischer ratio (Branched chain amino acids/Aromatic amino acids ratio).
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Until present time the treatment of hepatic encephalopathy is mainly aimed at reducing the production and intestinal absorption of ammonia by antibiotics and non-absorbable disaccharides, although the available data indicate a low success rate of these strategies.
Beneficial effects of branched chain amino acids supplementation (BCAA) may be more pronounced in patients with marked depression of BCAA and/or low Branched chain amino acids/Aromatic amino acids (BCAA/AAA) ratio in extracellular fluid.
It also may be suggested that the beneficial effect of long term intake of BCAA on hepatic encephalopathy demonstrated in clinical studies is related to improved muscle mass and nutritional status.
The current recommendation only includes oral BCAA to patients with liver disease who are intolerant to standard protein intake.
The rationale for this limitation is based on the fact that in the mentioned randomized trials, hepatic encephalopathy was not part of the inclusion criteria. Additionally, the positive effect was difficult to interpret as it was observed on compound end points, which combine survival, hospitalization, and cirrhosis complications. From these results, it is not possible to ascertain the role of BCAA in hepatic encephalopathy, which patients benefit and to what extent .
For this reason, the investigators designed this study to assess effectiveness of BCAA in improving clinical, nutritional and laboratory status of these patients.
