Aim

Immunoglobulin A vasculitis (IgAV) is classified as a leukocytoclastic vasculitis characterized by immune deposits in endothelial walls of small vessels causing vascular endothelial injury. The aim of the present study is to evaluate levels of vascular endothelial growth factor-A (VEGF-A) and VEGF receptor-1 (VEGFR-1) levels in adult IgAV patients.

Method

Thirty-seven adult IgAV patients admitted to the Rheumatology Clinic meeting the IgAV American College of Rheumatology (ACR) criteria and 32 control subjects were enrolled in the study. Disease activity was categorized as "remission" or "active" according to Birmingham Vasculitis Activity Score (BVAS). Serum VEGF-A, VEGFR-1 levels and VEGFR-1/VEGF-A ratio were evaluated in patient and control groups.

Results

Serum median VEGF-A, VEGFR-1 and VEGFR-1/VEGF-A ratios were significantly higher in the patient group when compared to controls (235.9 [155-308.4] pg/mL vs. 78.8 [29.7-210.3] pg/mL, 400 [277.2-724.3] pg/mL vs. 31.5 [12.5-214.4] pg/mL and 1.85 [0.57-2.97] vs. 0.46 [0.38-0.63] respectively, all P values <.001). VEGFR-1 had the strongest predictive value with a cut-off value of 0.6 with 75% sensitivity and 73% specificity (P < .001).

Conclusion

This study is the first report indicating elevated serum VEGF-A, VEGFR-1, and more importantly VEGFR-1/VEGF-A ratio can be good representatives of the inflammatory processes together with vascular endothelial injury in adult IgAV patients. VEGFR-1 seems to be a more important indicator of the ongoing inflammation."xsd:string
