Abstract
Intracranial aneurysm (IA) lingers as a potentially devastating clinical problem, in which inflammation acts as a critical contributor to the pathogenesis of this disease. Cytokines play a major role in regulating inflammation. The aim of this study was to gain insight in the inflammatory response in IA by assessing plasma cytokine profiles. Plasma levels of 10 cytokines were quantified by multiplex protein arrays in 66 patients with IA and 78 healthy controls. Results showed that plasma level of interleukin 1 beta (IL-1β) was 2.4-fold higher in patients than in controls (p < 0.05). The level of monocyte chemoattractant protein-1 (MCP-1) was 2.8-fold higher in patient than in controls (p < 0.01). The level of tumor necrosis factor-alpha (TNF-α) was 2.1-fold higher in cases than in controls (p < 0.001). When comparing the expression of cytokines in IA patients with different characteristics, cases with ruptured aneurysm revealed increased level of MCP-1 than those with unruptured aneurysm (p < 0.05), whereas cases with multiple numbers of aneurysms demonstrated higher levels of MCP-1 and TNF-α than those with single aneurysm (p < 0.05 and p < 0.05, respectively). These data indicated that IL-1β, MCP-1, and TNF-α were associated with increased risk of IA and may affect the development of this disease.
