Abstract

The metabolic derangement of sepsis leads to changes of the plasma and muscle amino acid (AA) pattern. In this study the influence of a septic process on liver AA pattern was investigated. In seven patients with abdominal sepsis, liver AA concentrations were determined during surgery and compared with those of four patients who had undergone cholecystectomy. In sepsis lowered AA levels were found for most of the AAs. Outstanding decreases exhibited the levels of the gluconeogenetic AAs (especially threonine and alanine), the branched chain AAs, lysine, and taurine. In the patients who did not survive the septic process, the depletion of these AAs was even amplified. Slightly increased AA levels were analyzed for p-ethanolamine, cystathionine, citrulline, β-alanine, tyrosine, and phenylalanine. The results indicate a disturbed free AA pattern of the septic liver. Despite the increased flux of gluconeogenetic AA from muscle to liver in sepsis, as reported by several authors, no accumulation of these AAs occurs in the liver.
