Abstract

Growth arrest-specific protein 6 (Gas6) is a serum protein involved in granulocyte, platelet and endothelium interaction, and is implicated in both anti-inflammatory response as well as platelet/leukocytes activation. We investigated serum Gas6 level in different clinical manifestations of systemic lupus erythematosus (SLE). Data were collected in 83 patients with SLE and 40 non-lupus controls. The Gas6 levels were detected by enzyme-linked immunosorbent assay. Our results demonstrated that the Gas6 level was higher in SLE patients as compared to the non-lupus control subjects (SLE vs. non-lupus control, median [inter-quartile range (IQR)] 22.67 [19.40-28.60] vs. 18.97 [16.05-20.62] ng/mL, p <0.01). Furthermore, Gas6 level was higher in patients with nephritis (nephritis vs. non-nephritis, median [IQR] 26.21 [21.17-31.61] vs. 22.22 [18.98-26.98] ng/mL, p = 0.03) and in patients with cutaneous vasculitis (vasculitis vs. non-vasculitis, median [IQR] 27.89 [23.24-34.26] vs. 22.30 [19.32-27.16] ng/mL, p = 0.03). Our results indicate that the serum Gas6 level is increased in SLE patients with lupus nephritis or cutaneous vasculitis, implicating a potential to serve as a SLE disease activity marker.
