Abstract/OtherAbstract:
In this study the authors assessed the sequential release of lipid mediators (TXB2, PGE2, 6-keto-PGF1alpha, LTB4, LTC4, PAF), pro-inflammatory cytokines (IL-6, IL-8, TNF-alpha) and anti-inflammatory cytokines (IL-4, IL-10) in 17 patients undergoing coronary artery bypass graft (CABG) with extracorporeal circulation (ECC). Time course of appearance of inflammatory mediators revealed the early and transient increase in lipid mediator plasma concentrations (6-keto-PGF1alpha, LTB4, LTC4, PAF) whereas cytokines (IL-6, IL-8, IL-10) were involved only in late pre- and post-operative periods. No variation of TXB2, PGE2, IL-4 and TNF-alpha levels were found. No correlation was documented between the levels of lipid mediators and pro- or anti-inflammatory cytokines suggesting that lipidic compounds are not implicated in the genesis of cytokines which appear much later involved. Despite the common use of high doses of aprotinin (a non-specific enzyme inhibitor) in hope to abrogate the inflammatory response to cardiopulmonary bypass procedure, this study reports the persistent release of several inflammatory compounds that might be involved in the post-CABG multiple organ failure syndromes.
