Abstrakt:	Objectives: We aimed to reveal evidence of endothelial dysfunction in the development of anti-melanoma differentiation-associated gene 5 (MDA5) dermatomyositis (DM). Methods: Thirty anti-MDA5 DM patients were enrolled and compared with patients with polymyositis (PM) (n=10) and healthy controls (n=20). The concentrations of soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular cell adhesion molecule-1 (sVCAM-1), endothelin-1 (ET-1) and von Willebrand factor (vWF) as well as interferon-alpha (IFN-α) and Galcetin-9 in the peripheral blood were tested by enzyme-linked immunosorbent assay (ELISA). Results: Plasma levels of sICAM-1, sVCAM-1, ET-1 and vWF were higher in the anti-MDA5 DM patients than in either the healthy controls or the PM patients. In the anti-MDA5 DM cohort, the ET-1 and vWF levels were significantly lower in the cases without cutaneous ulcers and ILD than the other cases. There was a strong positive relationship between the concentrations of ET-1 and Galectin-9 in the anti-MDA5 DM group. Conclusions: Our data suggest that endothelial dysfunction may be involved in the development of anti-MDA5 DM.
