It is well demonstrated that obesity is an independent risk factor for cardiovascular diseases. Recent studies have shown that obesity, insulin resistance and atherosclerosis are closely related phenomena in which low-grade inflammatory state and prothrombotic condition has pivotal roles. It has been shown that CD40-soluble CD40 ligand (sCD40L) interactions might constitute an important mediator for vascular inflammation. The aim of the present study was to assess sCD40L in relation to hs-CRP and cardiovascular risk factors in relation to body mass index (BMI).

Serum sCD40L and hs-CRP concentrations were measured in 52 obese patients and 28 non-obese subjects by ELISA. Insulin resistance was calculated by homeostasis model assessment-insulin resistance (HOMA-IR). We divided the participants into three groups depending in their BMI levels (Group 1 …
