Summary
Behçet's disease may impact haemostatic function, showing lower thrombomodulin and higher von Willebrand factor (vWF) and tissue plasminogen activator (tPA). Vascular involvement in Behçet's patients correlated with elevated vWF and tPA levels.
Area of Science:
- Rheumatology
- Vascular Biology
- Haematology
Background:
- Behçet's disease is a multisystem inflammatory disorder.
- Haemostatic function and endothelial activity are crucial in its pathogenesis.
- Previous studies suggest a link between Behçet's disease and thrombotic events.
Purpose of the Study:
- To investigate the impact of Behçet's disease on haemostatic function.
- To assess markers of endothelial activity and coagulation activation in Behçet's patients.
- To explore differences between patients with and without vascular involvement.
Main Methods:
- Plasma levels of prothrombin fragment 1+2, tissue plasminogen activator (tPA), protein S and C, antithrombin, fibrinogen, von Willebrand factor (vWF), and thrombomodulin were measured.
- 127 consecutive Behçet's disease patients were studied, including 34 with a history of vascular involvement.
- Measurements were performed in a University Hospital setting.
Main Results:
- Soluble thrombomodulin levels were significantly lower in Behçet's patients.
- Von Willebrand factor (vWF) and tissue plasminogen activator (tPA) levels were significantly higher in Behçet's patients.
- Patients with vascular involvement exhibited the highest vWF and tPA levels; no coagulation activation was observed.
Conclusions:
- Behçet's disease shows indirect signs of endothelial activity or damage.
- Endothelial markers are particularly altered in Behçet's patients with vascular involvement.
- Coagulation activation was not detected in the studied patient cohort.
