title: Endotoxemia in organ donors: graft function following liver transplantation.
abstract: Translocation of endotoxin (LPS) to the portal-venous system is produced by multiple factors. In the case of normal liver function, LPS is rapidly cleared from the portal blood by Kupffer cells; in impaired liver function, LPS can reach the systemic circulation. The objective of this study was to investigate whether elevated donor endotoxin levels affect graft function in the recipient. LPS levels in donor plasma were measured in 14 consecutive liver transplantations. Grafts with donor LPS levels < or = 12 pg/ml had a function probability of 100% after 600 days (n = 10). LPS concentrations of > 12 pg/ml in donor plasma led to loss of function in 75% of the liver grafts (n = 4; P = 0.003; Wilcoxon). Elevated LPS values in donor plasma seem to impair the prognosis of the grafts and could predict poor graft function as early as at the time of brain death.
