Aminosäurengemische zur parenteralen Ernährung bei Leberinsuffizienz

Abstract: Nutritive Aminosaurengemische können bei Leberkrankheiten die Konzentrationen von Plasma- und Hirnaminosäuren bis zu extremen Werten verändern oder weitgehend normalisieren. Erhöhte Plasmaspiegel des Methionins und zyklischer Aminosäuren sowie erniedrigte Spiegel von Valin, Leuzin und Isoleuzin fördern die hepatische Enzephalopathie (HE). Um eine parenterale Ernährung ohne Risiken zu ermöglichen, sind Aminosäuren-Korrekturlösungen vorgesehlagen worden. 73 Zirrhosekranke ohne und mit HE erhielten 8 bis 14 Tage … Show more

“…The above considerations have prompted the suggestion that patients with portalsystemic encephalopathy may benefit from therapy directed towards the restoration of a normal amino acid pattern . Administration of amino-acid solutions enriched with BCAA is reported to result in partial normalization of the plasma amino acid pattern and favourable clinical results Holm et al, 1978). Recently, intravenous infusion of leucine or a mixture of the three BCAA to healthy subjects has been shown to elicit a marked fall in the arterial Concentration of the aromatic amino acids and methionine as well as an inhibition of the cerebral uptake of methionine (Hagenfeldt, Eriksson & Wahren, 1980;Eriksson, Hagenfeldt & Wahren, 1980).…”

“…In contrast to the therapy successes achieved in hepatic failure and sepsis [74][75][76][77][78], it has not yet been possible to demonstrate that amino acid solutions with a high proportion of branched-chain amino acids positively influence the metabolism of the multiple trauma patient without sepsis [79]. In our opinion, therefore, amino acid therapy of patients who have undergone multiple trauma should not involve routine application of solutions containing an unphysiologically high proportion of branched-chain amino acids.…”
