Investigation of interleukin-8 serum concentration in patients undergoing different types of open heart surgical procedures with the extracorporeal circulation

Serum concentrations of proinflammatory cytokine interleukin-8 (IL-8) in 15 patients with surgically revascularized myocardium by triple venous cardiopulmonary bypass (CPB x 3) and in 10 patients with implanted artificial aortic valves (AV) were measured. Average IL-8 concentrations in “CPB x 3” patients and in those with artficial aortic valve were 7,3 +/- 11,6 pg/mL 24 hours before surgery, i.e. 3,3 +/- 3,4 pg/mL; six hours after surgical procedure 32,7 +/- 71,4 pg/mL, i.e. 8,9 +/- 9,9 pg/mL; and 24 hours after surgery 10,9+/-9,7pg/mL, i.e. 8,3 +/- 4,6 pg/mL. Extracorporeal circulation (ECC) caused significant increase of IL-8 serum concentration in both investigated groups six hours after surgery. Comparing preoperative values of the both groups, as well as those of 6 and 24 hours after surgery, no significant values of IL-8 were found. Various types of open heart surgical procedures had no influence on the extent of the production and secretion of proinflammatory IL-8 cytokine measured in patients during 24 hours after surgery
