[Fisher's index as indicator of severity and its course in the postoperative period following liver transplantation in children].

OBJECTIVES: To study the evolution of Fisher index during the early postoperative period after liver transplantation in children. PATIENTS AND METHODS: We have studied 32 liver transplants performed on 26 pediatric patients, during the first week of the post-operative period. In all cases the BCAA/AAA quotient was determined before transplant, at the time of PICU admission, and on days 1, 2, 3, 4, 5, 6 and 7 after transplant. RESULTS: Compared to control group values, the Fisher index for these patients is significantly lower at pre-transplant (p < 0,0001), upon admission (p < 0,001), and days 1 (p < 0,0001), 2 (p < 0,0001) and 3 (p < 0, 0001). Comparison between non-survivors and survivors shows a significant reduction in the first group on the index in days 1 (p < 0,02), 3 (p < 0,02), 4 (p < 0,005), 5 (p < 0,002), 6 (p < 0,03) and 7 (p < 0,01) of post-transplant. CONCLUSIONS: The evolution of the Fisher index can be useful as an indication of the severity of the condition of these kinds of patients, which would help to establish more aggressive treatment to improve prognosis.

[Amino acid changes in blood of children with severe liver disease. The evaluation of differences according to distinct physiopathology].

OBJECTIVE: The aim of this study was to know the serum amino acid profiles in children with terminal hepatic diseases and to assess the differences between the two main physiopathological groups of hepatic damage: cholestasis and cellular necrosis. PATIENTS AND METHODS: We studied twenty-six pediatric patients with severe hepatic diseases admitted to the Pediatric Intensive Care Unit. Patients were divided into two groups according to the predominant hepatic lesion: cellular damage (fourteen children) and cholestasis damage (twelve cases). RESULTS: Overall, there is a significant increase in the aromatic amino acids (AAA) phenylalanine (p < 0.04) and tyrosine (p < 0.0003) and a decrease in the branched-chain amino acids (BCAA) leucine, isoleucine and valine (p < 0.00001), with a reduction in the BCAA/AAA ratio (p < 0.00001). However, we found a significant decrease in glutamine, cysteine, taurine, serine, threonine, tryptophan, total amino acids and essential amino acids, together with higher levels of glutamic acid, ornithine and citrulline, which reflects a more complex metabolic disturbance. The group with cholestatic damage shows very low taurine levels (p < 0.0003). Patients with predominantly cellular damage have higher increases in tyrosine (p < 0.01), phenylalanine and hydroxyproline (p < 0.01). CONCLUSIONS: These findings may help us to better understand the complex physiopathology of amino acid metabolism in different liver diseases. Moreover, the extremely low levels of taurine found prompted us to recommend additional dietary support particularly in children with cholestatic hepatopathy.
