title: Anti-endothelial cell antibody, thrombomodulin, and von Willebrand factor in idiopathic inflammatory myopathies.
abstract: Sera from 19 patients with idiopathic inflammatory myopathy (IIM) were examined for the presence of anti-endothelial cell antibodies (AECA) by an immunoglobulin G-specific cellular enzyme-linked immunosorbent assay. The mean binding index of AECA was found to be 37.7% +/- 26.5% for the patients, compared with a mean of 7.2% +/- 2.7% for normal controls (P < 0.04). Levels of thrombomodulin, von Willebrand factor antigen, and serum creatine kinase were also shown to be augmented. Interestingly, positive correlations between AECA on the one hand and Raynaud's phenomenon and interstitial lung disease on the other were demonstrated. Given that the pathogenesis of IIM remains uncertain, these findings may be of importance.
