Interleukin-6 (IL-6) and monocyte chemotactic and activating factor/monocyte chemoattractant protein-1 (MCAF/MCP-1) play pivotal roles in systemic inflammation, immune response, and tissue damage after cardiopulmonary bypass (CPB). Previous reports have described transient rises in IL-6 and MCAF after CPB, but the data seem to vary according to the different surgical procedures used. To evaluate the influence of the different surgical procedures on the proinflammatory cytokine responses, we compared perioperative serum IL-6 and MCAF release in coronary artery bypass grafting (CABG) and valvular surgery cases. Eighteen CABG (CABG group) and 7 single valvular cardiac surgery patients (valve group) were included in this study. Blood samples were taken to measure the serum concentrations of IL-6 at the induction of anesthesia, at the removal of the aortic cross-clamp, at the end of CPB, at the end of surgery, and 24 h after the termination of surgery. Serum IL-6 and MCAF were assayed by ELISA. Serum IL-6 increased immediately after aortic declamping and reached its peak at the end of surgery in both groups. Serum IL-6 concentrations at the end of surgery and 24 h after surgery were significantly higher in the valve group than in the CABG group (123.9 +/- 21.7 pg/ml vs. 79.7 +/- 10.4 pg/ml, p = 0.049; 113.6 +/- 25.0 pg/ml vs. 39.9 +/- 11.5 pg/ml, p = 0.006, respectively). Serum MCAF increased immediately after aortic declamping, and the MCAF level at the end of surgery was significantly higher in the valve group than in the CABG group (1118.4 +/- 353.9 pg/ml vs. 241.0 +/- 71.2 pg/ml, p = 0.002, respectively). IL-6 and MCAF may play important roles in the pathophysiology of surgical damage with CPB, and the different surgical procedures appear to affect the proinflammatory cytokine release after cardiac surgery differently.
