Combined therapy with gas gangrene antitoxin and recombinant human soluble thrombomodulin for Clostridium perfringens sepsis in a rat model
2018
Abstract Cases of Clostridium perfringen s septicemia, such as liver abscess, often develop a rapidly progressive intravascular hemolysis and coagulation; the mortality rate with current standard care including antibiotics and surgery is high. Herein, we firstly investigated the effects of gas gangrene antitoxin (GGA) (antitoxin against C. perfringens ) and recombinant human soluble thrombomodulin (rTM) on the hemolysis, coagulation status, inflammatory process, and mortality in α-toxin-treated rats. Male 11-week-old Sprague Dawley rats were randomly divided into five groups: control group, α-toxin group, GGA group, rTM group, and combined GGA and rTM (combination group). After α-toxin injection, mortality and platelet counts, and hemolysis were observed for 6 h. The fibrin/fibrinogen degradation products (FDP), and plasma high-mobility group box 1 (HMGB1) were also measured at 6 h. The combination group demonstrated 100% survival compared with 50% survival in the α-toxin group and demonstrated significantly improved hemolysis, platelet counts, and lactate levels compared with those in the α-toxin group (p C. perfringens sepsis.
