Serum concentrations of three angiogenic cytokines: vascular endothelial growth factor (VEGF), stromal cell-derived factor-1 (SDF-1) and placental growth factor (PIGF) and soluble vascular cell adhesion molecule 1 (sVCAM-1), were investigated in the serum of 61 patients with systemic lupus erythematosus (SLE) and 20 healthy subjects. The possible association between serum levels of these proteins and SLE activity, as well as correlation between the concentrations of cytokines were also analysed. All of these factors were detectable in all SLE patients and the healthy control group. The median concentration of VEGF was higher in active SLE (386 pg/mL) than in inactive disease (327 pg/mL) or in the control group (212 pg/mL, p<0.004). The median serum level of SDF-1 was higher in SLE patients (1,814 pg/mL) than in the control group (1,507 pg/mL, p<0.02). The median concentration of PIGF was higher (14 pg/mL) in SLE patients than in the control group (12 pg/mL, p=0.03), and particularly in active disease (17 pg/mL) as compared to the inactive phase (13 pg/mL, p=0.01). The correlations between the levels of cytokines examined and clinical features, laboratory abnormalities and the type of treatment were also analysed. We found a positive correlation between serum concentrations of PIGF and SLE activity according to SLAM score (p=0.33, p=0.13).
