Abstract
BackgroundEndotoxin (Et) in the portal vein blood is processed by the hepatic reticuloendothelial system. Thus, it is possible that the Et kinetics of the peripheral venous blood may be useful as a biological index that can be used to evaluate liver function. In this study, we measured Et using the endotoxin activity assay in peripheral venous blood during living donor liver transplantation (LDLT), to study its clinical significance. MethodsSubjects were 17 patients who underwent LDLT. In the perioperative peripheral venous blood, was measured Et activity (EA) using the endotoxin activity assay at 1 or 2 d before LT, and then on 1, 5, 7, 14, and 21 postoperative days. ResultsPatients with infections had significantly higher EA levels compared with those without complications before LDLT and 14 postoperative days (P = 0.038 and 0.027, respectively). The average EA level of patients with infections and without complications before LT was 0.22 and 0.08, respectively (P = 0.038). Patients with an EA level higher than 0.20 before LDLT had a significantly longer period of hospitalization compared with those without complications (P = 0.038). ConclusionsA preoperative EA level more than 0.20 is a high risk factor for post-transplant infection and a prolonged period of hospitalization.
