Increased serum levels of soluble vascular cell adhesion molecule-1 and E-selectin in patients with systemic
1Department of Dermatology, Faculty of Medicine, University of Tokyo, Japan.
Objective:
To determine the serum levels of soluble vascular cell adhesion molecule-1 (sVCAM-1) and soluble E-selectin (sE-selectin) in patients with systemic sclerosis (SSc).
Method:
Serum samples from 80 patients with SSc and 20 healthy control subjects were examined by a sensitive enzyme-linked immunosorbent assay.
Results:
The serum levels of sVCAM-1 and sE-selectin were significantly higher in the patients with SSc than in the healthy controls. The serum levels of sVCAM-1 were correlated with the presence of pulmonary fibrosis, joint involvement and elevated erythrocyte sedimentation rate levels. The serum levels of sE-selectin were correlated with the presence of pulmonary fibrosis.
Conclusion:
These results suggest that endothelial activation is involved in the development of this disease.
