摘要

Cytokines play an extremely important role in the pathogenesis of coronary artery disease (CAD) in which interleukin (IL)-7 is a major regulator of T-cell homeostasis which is conced in the stimulation of leukocyte-endothelial cell adhesion during inflammatory events. Circulating IL-7 is associated with activation of monocyte and natural killer cells, leading to enhanced production of inflammatory cytokines and chemokines observed in atherosclerosis and acute coronary syndromes. Plasma levels of IL-7, hs-CRP and monocyte chemoattractant protein (MCP)-1 were measured by an immunoenzymatic ELISA technique. Ninety neuropathic diabetic foot patients were divided into two groups: group B [those without CAD (n=45)] and group C [those with higher risk of CAD (n=45)]. Thirty-five healthy subjects were included as control (group H). Plasma concentration of IL-7, MCP-1 and hs-CRP were significantly higher in group C as compare with group H and B. Plasma IL-7 levels also showed significant positive correlations with plasma levels of hs-CRP and MCP-1. Abnormalities in lipid profile were also observed. In conclusion the positive correlation between plasma concentration of IL-7, MCP-1 and hs-CRP in diabetic foot patients observed herein, suggests a plausible role for IL-7 in the promotion of clinical instability in coronary artery disease.
