PG - 411-4 AB - Interleukin-18 (IL-18) appears to play a critical role in cytokine-induced organ failure during endotoxemia in animal models. Therefore, plasma samples from patients with severe trauma and sepsis were examined for the presence of IL-18. Significantly elevated plasma IL-18 concentrations were found in patients with sepsis compared to severely injured patients and healthy humans. Septic patients who died and patients with septic shock exhibited higher levels of IL-18 than survivors and septic patients without shock. In addition, septic patients with gram-positive infections had significantly higher IL-18 plasma levels than patients with gram-negative infection. These findings were confirmed by whole blood assay from healthy humans where Staphylococcus aureus markedly (P < 0.05) increased the release of IL-18 in whole blood ex vivo, while endotoxin was ineffective. Although obtained from a small patient group, these results suggest that IL-18 production may discriminate between gram-positive and gram-negative sepsis, and that increased IL-18 appearance may be associated with an adverse outcome in septic patients.
