Methods: We examined stress-response patterns in plasma leptin, ghrelin, hsCRP, IL-6, cortisol and insulin levels before and up to 5 days after cardiopulmonary bypass in 20 patients with type 2 diabetes and 20 patients without diabetes. Results: Plasma leptin levels increased significantly in both groups (p < 0.05) and rose significantly higher in diabetics when compared with nondiabetic patients (p = 0.004). Plasma ghrelin levels increased significantly only in diabetics (p = 0.033). Patients with and without diabetes showed significantly elevated serum concentrations of IL-6, hsCRP, cortisol and insulin (p < 0.005 for IL-6, hsCRP; p < 0.05 for cortisol, insulin) but the difference between the two groups was nonsignificant. Leptin was independently predicted by hsCRP (p < 0.05, F = 2.9), gender (women p < 0.001, F = 4.7), body mass index (BMI p < 0.0001, F = 6.1) whereas ghrelin levels were not associated with any variables in the total patient population. (critical F = 2.26, p <= 0.05). Conclusions: Acute phase response in diabetics differs by higher leptin levels independent of BMI, gender and IL-6, hsCRP, insulin and cortisol levels.
