Abstract
Omentin-1 is a novel adipokine with anti-inflammatory functions. Apelin is associated with hyperinsulinemia and pathological angiogenesis. Chemerin has both pro- and anti-inflammatory actions and implicated in insulin resistance and metabolic syndrome. The aim of this study was to assess serum omentin-1, apelin and chemerin concentrations and to investigate their association with the presence and severity of DR in T2DM patients. Serum omentin-1, apelin and chemerin were measured in 112 patients with DR and 56 patients without DR. Bivariate analysis showed omentin-1 correlated negatively with hsCRP and TyG index; while apelin correlated positively with chemerin. Linear regression data showed that apelin and chemerin were independent predictors of DR severity. ROC curve revealed that omentin-1 was the best discriminant for DR while apelin was the best discriminant for vision threatening retinopathy. Serum omentin-1 concentration correlates negatively, while serum apelin and chemerin concentrations correlate positively with DR presence and severity in T2DM patients.
