title: Deep vein thrombosis and systemic inflammatory response: a pilot trial.
abstract: BACKGROUND
  Symptoms of deep vein thrombosis as swelling, erythema, pain and calor have been suspected of being caused by an inflammatory reaction of the affected leg. We therefore performed a prospective pilot trial to study a possible systemic inflammatory response induced by deep vein thrombosis.
  
  
  METHODS
  We determined white blood cell count and plasma C-reactive protein in 100 consecutive patients with suspected deep vein thrombosis. The final diagnosis was based on the results of duplex sonography or ascending venography.
  
  
  RESULTS
  Deep vein thrombosis was diagnosed in 37 patients (37%). White blood cell count (P = 0.012) and plasma C-reactive protein values (P < 0.001) were significantly increased in patients suffering from deep vein thrombosis. There was no correlation of white blood cell count or C-reactive protein with the thrombotic burden or the duration of symptoms.
  
  
  CONCLUSIONS
  In patients with deep vein thrombosis, thrombus formation and consequent vein wall damage induce a systemic inflammatory reaction which is reflected by significantly increased levels of white blood cells and plasma C-reactive protein.
