  • Title: Antibody to endotoxin core glycolipid reverses reticuloendothelial system depression in an animal model of severe sepsis and surgical injury.
    Author: Aldridge MC, Chadwick SJ, Cheslyn-Curtis S, Rapson N, Dudley HA.
    Journal: J Trauma; 1987 Oct; 27(10):1166-72. PubMed ID: 3312624.
    Abstract:
    To study the effect of severe sepsis on the function of the reticuloendothelial system (RES) we have measured the clearance kinetics and organ distribution of both low-dose technetium tin colloid (TTC) and 75selenomethionine-labelled E. coli in rabbits 24 hours after either sham laparotomy or appendix devascularization. Sepsis resulted in similar delayed blood clearance and reduced liver (Kupffer cell) uptake of both TTC and E. coli. To investigate the ability of polyclonal antibody to E. coli-J-5 (core glycolipid) to improve RES function in the same model of sepsis, further animals were pretreated with either core glycolipid antibody or control serum (10 ml IV) 2 hours before induction of sepsis. TTC clearance kinetics were determined 24 hours later. Antibody pretreated animals showed: a reduced incidence of bacteremia; normalization of the rate of blood clearance and liver uptake of TTC; and a 'rebound' increase in splenic uptake of TTC. We conclude that antibody to E. coli-J-5 enhances bacterial clearance by the RES.
