Abstract

The aim of this study was to establish the incidence of endotoxemia and the influence of endotoxin on specific antibody response after multiple injury. Blood samples were collected from 39 patients (median Injury Severity Score: 20.5) at 0-3 and 6-12 hours, and 1, 3, 5, and 10 days after admission. The endotoxin plasma levels were high at the first time point (mean = 0.421 endotoxin units/mL) and decreased in the later course. Total immunoglobulin levels of IgM, IgG, or IgA were low and increased throughout the observation period. Specific antibodies of the IgM class against two lipid A and four lipopolysaccharide preparations increased transiently but significantly on day 3 and/or day 5. No changes of specific antibody content against endotoxin or lipid A was seen in the IgG or IgA class. The specific antibody content of the different classes against alpha-hemolysin of Staphylococcus aureus did not differ during 10 days after trauma. The specific antibodies of the IgM class reacted with all lipid A and LPS lipopolysaccharide preparations demonstrating cross-reactivity. These results suggest that endotoxin may be a specific stimulator of IgM antiendotoxin antibody secretion following trauma.
