Atherosclerosis in Behçet's Syndrome

Area of Science:

• Vascular Medicine
• Rheumatology
• Cardiology

Background:

• Behçet's syndrome (BS) is a multisystem inflammatory disease.
• Preliminary evidence suggested atherosclerosis may not be elevated in BS.
• This study aimed to investigate subclinical atherosclerosis in BS patients.

Purpose of the Study:

• To evaluate the presence of subclinical atherosclerosis in a large cohort of Behçet's syndrome patients.
• To compare atherosclerosis markers between BS patients with different disease manifestations and control groups.
• To assess the impact of major organ involvement on atherosclerosis in BS.

Main Methods:

• A cross-sectional study involving 239 Behçet's syndrome patients, 100 rheumatoid arthritis patients, 74 ankylosing spondylitis patients, and 156 healthy controls.
• B-mode ultrasonography was used to measure carotid and femoral artery intima-media thickness (IMT) and plaque frequency.
• Traditional atherosclerotic risk factors were assessed, and analyses were conducted separately for men and women.

Main Results:

• No significant differences in carotid and femoral artery plaque frequency or IMT were observed between Behçet's syndrome patients, ankylosing spondylitis patients, and healthy controls.
• Subgroup analysis of BS patients (mucocutaneous/joint disease vs. major organ involvement) showed similar atherosclerosis markers.
• Only men with rheumatoid arthritis exhibited a significantly higher frequency of carotid artery plaques after adjusting for risk factors.

Conclusions:

• Elevated atherosclerosis is not a prominent characteristic of Behçet's syndrome, even in patients with major organ involvement.
• The findings suggest that BS itself does not confer a substantially increased risk for atherosclerosis.
• Further research may explore specific inflammatory pathways in BS and their relationship with vascular health.
