BackgroundThe objective of this study was to investigate the effect of the perioperative use of methylprednisolone in medium doses on markers of endothelial cell activation in patients with coronary artery disease undergoing cardiopulmonary bypass.MethodsIn this prospective, double-blinded, placebo-controlled, randomised study, 44 patients, undergoing a coronary artery bypass graft surgery received either methylprednisolone 20 mg/kg or a placebo intraoperatively after anaesthesia induction. The primary endpoint was endothelin-1, and secondary endpoints were E-selectin, interleukin (IL)-6 and IL-10, PaO2/FiO2 coefficient, and microalbuminuria.ResultsEndothelin-1 was higher in the study group postoperatively at 10 min (p = 0.0008), 2 h (p = 0.02), 4 h (p = 0.005), and 24 h (p = 0.004). IL-6 was lower in the study group postoperatively at 2 h (p = 0.03), 4 h (p = 0.04), and 24 h (p < 0.0001). IL-10 was higher in the study group postoperatively at 10 min (p < 0.0001), 2 h (p = 0.009), and 4 h (p = 0.001). PaO2/FiO2 was lower in the study group at 24 h after surgery (p = 0.03). Microalbuminuria was similar in both groups.ConclusionDespite an obvious anti-inflammatory effect, methylprednisolone causes endothelial cell activation in patients undergoing cardiopulmonary bypass.
