Serum vascular endothelial growth factor is a biomolecular biomarker of severity of diabetic retinopathy

Original language description

BackgroundElevated serum vascular endothelial growth factor (VEGF) levels are associated with diabetic retinopathy (DR). Serum VEGF levels correlate with vitreous levels. Neuroretinal changes occur even before the appearance of vascular signs in DR. Role of VEGF as a biomarker for DR has not been assessed. Serum VEGF as a biomarker for severity of DR, was evaluated for the first time.MethodsConsecutive cases of type 2 diabetes mellitus [without DR, (no DR, n=38); non-proliferative DR, (NPDR, n=38); proliferative DR, (PDR, n=40)] and healthy controls (n=40) were included. Serum VEGF was measured using enzyme linked immunosorbent assay. Accuracy of VEGF as a biomarker for severity of retinopathy was measured using the area under the receiver operator characteristic (ROC) curve.ResultsSerum VEGF levels in controls, No DR, NPDR and PDR groups showed significant incremental trend from 138.96 +/- 63.37 pg/ml (controls) to 457.18 +/- 165.69 pg/ml (PDR) (F=48.47; p&lt;0.001). Serum VEGF levels were observed to be significantly elevated even before DR had set in clinically. ROC for serum VEGF levels was significant in discriminating between the cases and the controls and had good accuracy in discerning between subjects with and without retinopathy. The area under curve (AUC +/- SE) for discrimination was significant: (a) cases and controls (n=156): AUC=0.858 +/- 0.029, p&lt;0.001; (b) DR (NPDR+PDR) and No DR (n=116): AUC=0.791 +/- 0.044, p&lt;0.001; and (c) NPDR and PDR (n=78): AUC=0.761 +/- 0.056, p&lt;0.001, with over 90% projected sensitivity and specificity at various cut off values.Conclusion Serum VEGF level is a simple, effective laboratory investigative test in predicting the onset of DR in eyes showing no evidence of DR and serves as a reliable biomolecular biomarker for severity of DR.
