The induction of early-phase endotoxin tolerance in a procine endotoxin shock model by atoxic LPS from Rhodobacter sphaeroides led to a significant extension of the survival time (p < 0.0179). The ...protective effect of the non-specific tolerant state also led to an enhancement of cardiorespiratory parameters during the continuous endotoxin challenge. Non-specific stimulation of host defense mechanisms with atoxic endotoxin as prophylactic agent in surgical patients at risk may prove to be beneficial in the future.
In three fatal cases of clostridial myonecrosis, the following criteria were found: repeated intramuscular injections over several years with anti-inflammatory substances, delay in diagnosis in ...outpatient care, and following uncontrollable systemic septic complications, despite radical surgical treatment. Only early, aggressive surgical interventions can stop the rapid course of necrotizing soft-tissue infections.
After induction of early-phase endotoxin tolerance in a porcine endotoxin shock model over a period of 3-4 days a highly significant survival-time extension (p < or = 0.0001) was achieved. The ...protective effect of the unspecific tolerant state led to a significant enhancement of cardiorespiratory parameters during the continuous endotoxin challenge. However, the level of tolerance is relative and can be overcome by increasing the endotoxin challenge dose.

Journal Article
In a porcine endotoxin shock model using a continuous intravenous endotoxin infusion of 250 ng/kg body weight per hour, the cardiorespiratory and hematologic parameters were studied while applying a ...new on-line polymyxin B immobilized adsorption system. This preliminary report shows that the new adsorbent can remove endotoxin selectively from the circulation and confers a good amount of protection from endotoxin-induced cardiopulmonary decompensation as well as hematologic alterations. Survival time could be extended from 216 min to 313 min. Whereas cardiac output and mean arterial pressure declined critically after 3 h in the controls, the treated group remained stable for another 3 h. These data show that endotoxin adsorption by polymyxin B coupled covalently to acrylic spheres as an adjunctive on-line measure in the septic syndrome seems feasible.
