Thrombosis in Behçet's disease: a retrospective survey from a single UK centre

Area of Science:

• Rheumatology
• Vascular Medicine
• Immunology

Background:

• Behçet's disease (BD) is a rare multisystem inflammatory disorder.
• Vascular complications, including thrombosis, are a significant concern in BD.
• Understanding the prevalence and risk factors for thrombosis in BD is crucial for patient management.

Purpose of the Study:

• To investigate the prevalence and relative risk of vascular occlusion and thrombosis in Caucasian patients with Behçet's disease.
• To compare thrombosis rates between BD patients and a control group.
• To analyze gender-specific differences in thrombosis risk and associated symptoms in BD.

Main Methods:

• Retrospective cohort study involving 73 Caucasian patients with BD and 146 controls.
• Data collected from patients attending the Immunology/Rheumatology Department.
• Statistical analysis to determine the relative risk of thrombosis, adjusting for age and gender.

Main Results:

• Thrombosis was significantly more frequent in BD patients (32%) compared to controls (5%).
• Venous thrombosis was the predominant type, occurring in 25% of BD patients versus 3% of controls.
• BD conferred an 11-fold increased risk of any thrombosis and a 14-fold increased risk of venous thrombosis. Male BD patients had a 6-fold higher risk of vein thrombosis.

Conclusions:

• Behçet's disease significantly elevates the risk of venous thrombosis, with a 14-fold higher incidence in the studied Caucasian population.
• Male BD patients exhibit a substantially higher risk of vein thrombosis (sixfold) and are more prone to thrombophlebitis, folliculitis, and retinal vasculitis.
• These findings highlight the critical need for vigilant monitoring and management of vascular complications in patients with Behçet's disease, especially in males.
