Serum omentin levels: A possible contribution to vascular involvement in patients with systemic sclerosis
Abstract
Adipokines have been shown to be potentially involved in various pathological processes of systemic sclerosis (SSc), including inflammation, vasculopathy and fibrosis, through their pleiotropic effects. Omentin is a member of the adipokines, and has a protective effect against vascular inflammation and pathological remodeling leading to atherosclerosis as well as a vasodilatory effect. To assess the potential role of omentin in the development of SSc, we determined serum omentin levels by enzyme-linked immunosorbent assay in 66 SSc and 21 control subjects and evaluated their clinical correlation. Serum omentin levels were significantly decreased in diffuse cutaneous SSc patients compared with limited cutaneous SSc patients, while comparable between total SSc patients and healthy controls. In diffuse cutaneous (dc)SSc, patients with a disease duration of 5 years or less had serum omentin levels significantly lower than those with a disease duration of more than 5 years. In total SSc, serum omentin levels were significantly higher in patients with elevated right ventricular systolic pressure than in the others, while serum omentin levels did not correlate with fibrotic and systemic inflammatory parameters. These results suggest t...Continue Reading
