Abstract
Background High-mobility group box 1 (HMGB-1) is a key substance mediating inflammation and development of atherosclerotic lesions (ALs), including abdominal aortic aneurysms (AAA). Serum levels of HMGB-1 are increased in patients with AAA than those in normal controls because the ALs in AAAs secrete HMGB-1. We therefore postulate that the serum HMGB-1 level should decrease after endovascular aortic repair (EVAR) or open aortic repair (OAR). However, there is no evidence of this in the literature. The purpose of this study was to investigate the changes in HMGB-1 levels after surgical intervention for AAA. We also aimed to determine if the HMGB-1 levels varied between the two procedures. Methods Serum HMGB-1 levels were determined in 24 patients with AAA and 25 healthy controls. Twelve of the 24 AAA patients underwent EVAR, whereas the other half underwent OAR. The relationship between HMGB-1 levels and presence of AAA or influence of operative methods on the serum HMGB-1 level were prospectively investigated. Results Serum HMGB-1 levels in AAA patients were significantly higher than those in healthy controls (9.4 ± 5.7 vs. 4.1 ± 2.0 ng/mL, P < 0.01). The serum HMGB-1 levels in both the EVAR group and the OAR group were significantly decreased from baseline at both 3 mo and 1 y after surgery. Conclusions Removal or isolation of AL via surgical intervention significantly decreases serum HMGB-1 levels. The significant postoperative reduction in HMGB-1 levels suggests that important endocrinological changes occur after surgical treatment of AAA.
