Abstract | BACKGROUND/AIMS: METHODOLOGY: First, in cases with a definitive clinical diagnosis of endotoxemia, we determined the serum endotoxin level by the ES (Endospesy) method, from the percentage of cells positive for membrane CD14, from the CD14 fluorescence intensity (MFI-CD14), and from the quantification of soluble CD14 ( sCD14); and calculated the diagnostic accuracy obtained with each. Next, in 13 cases of extended hepatectomy (in excess of lobectomy) the mCD14-positive rates were determined around the time of the operation, and compared with the clinical courses of infection foci, if any, and other findings. RESULTS: The diagnostic accuracy of endotoxemia obtained by ES, mCD14, MFI-CD14 and sCD14 were 77.3%, 95.5%, 86.7% and 66.7%, respectively, so that the highest was given by the positive mCD14 cell rate. Although no infectious complication was detected in any of the 9 patients in whom the mCD14-positive rates changed within the normal range, of the 4 patients in whom the mCD14-positive rates fell, 2 had cholangitis due to gram-negative bacilli, one who was infected by central vein catheterization, was thought to have exogenous endotoxemia; and the fourth, in whom no clear focus of infection was detected, ran a temperature of 38 degrees C (over 100 degrees F) of unknown origin for 16 days. In this last patient, gram-negative bacilli were detected in both the saliva and the gastric juice, and so endogenous endotoxemia was suspected. CONCLUSIONS: These results show that decrease in the mCD14-positive rate is more accurately diagnostic of endotoxemia than the endotoxin value obtained by the ES method, and was considered to be a definitive diagnosis of endotoxemia. In addition, from the reduction of the mCD14-positive rate after extended hepatectomy, it was considered that endogenous endotoxemia occurred in one case out of 13 (8%).
