title: Serum thrombomodulin. A novel marker of disease activity in systemic lupus erythematosus.
abstract: OBJECTIVE
  Soluble thrombomodulin (sTM), a proposed serum marker of endothelial cell injury, was investigated as a parameter of disease activity in patients with systemic lupus erythematosus (SLE).
  
  
  METHODS
  Levels of sTM were determined by enzyme-linked immunosorbent assay. Disease activity was assessed using 3 established scoring systems: the American College of Rheumatology (ACR), the New York Hospital for Special Surgery (NYHSS), and the Systemic Lupus Activity Measure (SLAM) systems.
  
  
  RESULTS
  A close correlation was found between sTM levels and disease activity as assessed with all 3 scoring systems: r = 0.52 by the ACR, 0.75 by the NYHSS, and 0.82 by the SLAM.
  
  
  CONCLUSIONS
  We found that sTM is a sensitive serologic marker of organ involvement in patients with SLE. Furthermore, sTM may prove to be an important marker for vasculitis in general.
