Background

Behçet's disease (BD) is a chronic inflammatory vasculitis affecting multiple organs. Uveitis is frequently seen in patients with BD, especially in Turkish population.

Objectives

To investigate vascular endothelial growth factor (VEGF) gene polymorphisms along with the levels of VEGF and VEGF receptors in patients with Behçet's uveitis (BU).

Material and methods

Fifty-five BD-associated uveitis patients and 30 ageand sex-matched controls were included in this case-control study. The genotypes of the single nucleotide poymorphisms (SNPs): rs2010963 (+405G), rs3025039 (+936T) and rs699947 (-2598A) of the VEGF-A gene were determined using real-time polymerase chain reaction (RT-PCR) and serum levels of VEGF and VEGF receptors were measured using enzyme-linked immunosorbent assay (ELISA).

Results

No associations of the VEGF gene polymorphisms were observed in BD uveitis patients, but arthritis was present in 53.3% of patients not possessing CT genotype in C3025039→T polymorphism (p = 0.024). Although there were no statistically significant differences in serum VEGF-A, VEGF-C and soluble vascular endothelial growth factor receptor-3 (sVEGFR-3) levels (p < 0.05), serum vascular endothelial growth factor receptor-1 (VEGFR-1) and sVEGFR-3 levels were significantly higher in the BD group (p < 0.001 and p = 0.001, respectively). In addition, VEGF-C/soluble vascular endothelial growth factor receptor-2 (sVEGFR-2) ratio was significantly higher (p < 0.001), while VEGF-A/VEGFR-1 and VEGF-C/sVEGFR-3 ratios were significantly lower (p < 0.001 and p = 0.033, respectively) in BD patients compared to controls. Also, VEGF-C/sVEGFR-3 (p = 0.024, r = 0.37) and VEGF-C/sVEGFR-2 (p = 0.020, r = 0.38) ratios were positively correlated with disease duration.

Conclusions

The significant changes in sVEGFR-3 levels and VEGF-C/sVEGFR-3 ratio has shown that lymphangiogenesis processes might take place in the pathogenesis of BD uveitis, and these parameters can be important indicators of evaluation of BD patients with uveitis together with disease duration."xsd:string
