Peripheral arterial disease (PAD) is a manifestation of systemic atherosclerosis, recognized as an inflammatory disease of the vessel wall, probably accelerated by diabetes mellitus (DM). Elevated interleukin (IL)-6 levels have been associated with increased cardiovascular morbidity and a common polymorphism has been identified in the promoter region of the IL-6 gene. The aim of this prospective study was to investigate inflammatory mediators in PAD patients (+/- DM) and to investigate a possible relationship to the IL-6 gene polymorphism. Five groups of patients (DM, intermittent claudication +/- DM, critical limb ischemia (CLI) +/- DM) and a control group of 20 individuals each were included. Hemoglobin, high sensitive C-reactive protein (hsCRP), creatinine, blood lipids, white blood cells (WBC); CD11b/CD18; vascular cell adhesion molecule (sVCAM-1), intercellular adhesion molecule (sICAM-1), sE-selectin, sP-selectin; IL-6, IL-8, tumour necrosis factor (TNF)alpha, sTNFalpha-R1 and sTNFalpha-R2 were analysed. The IL-6 gene polymorphism was determined in all groups and also compared with 200 healthy controls from a larger study of blood donors. In a multiple regression analysis, adjusted for gender, smoking and age, the effect of CLI was significantly (p < 0.05) associated with elevated levels of the WBC count, hsCRP, proinflammatory cytokines (IL-6, TNFalpha-R1-2) and endothelial (sICAM, sVCAM) and WBC (CD11b gran) markers. The effect of less advanced PAD (intermittent claudication) was related to an increased concentration of sVCAM-1 and the number of monocytes and granulocytes. DM or leg ulcers were not significantly related to any of the markers. No significant difference in frequency of the various IL-6 genotypes was found between the groups or when compared with the group of 200 blood donors (p> 0.3). Activation of cytokines, endothelial cells and WBC was related to the Fontaine stage of PAD but not to the presence of DM or ulcers. No association was found between the polymorphism in the IL-6 promoter region and PAD.

Peripheral arterial disease (PAD) is a manifestation of atherosclerotic vascular disease and is often associated with other comorbidities, such as hypertension, diabetes and dyslipidemia. An increasing body of evidence supports the notion that inflammation plays an important role in the development and progression of PAD. A number of studies have investigated the association of various acute phase proteins, particularly C-reactive protein (CRP), with PAD. Apart from CRP, other circulating biomarkers, such as matrix metalloproteinases (MMPs), selectins and interleukin (IL)-1, IL-2, IL-6, IL-8 and IL-10 have been considered to play a role in the development of PAD. In this review, the role of these circulating biomarkers in PAD is discussed. Current data indicate that the appropriate use of biomarkers in patients with PAD may contribute to an early diagnosis, an enhanced knowledge of the developmental process of the disease, as well as to the subsequent improvement of current therapies and to the development of new ones.
