Subclinical atherosclerosis in rheumatoid arthritis and systemic lupus erythematosus

Area of Science:

• Rheumatology
• Cardiovascular Medicine
• Immunology

Background:

• Rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) are linked to higher mortality, primarily from cardiovascular disease.
• Traditional cardiovascular risk factors do not fully explain increased cardiovascular risk in RA and SLE patients.
• Systemic inflammation in RA and SLE may accelerate atherosclerosis, a key contributor to cardiovascular events.

Purpose of the Study:

• To investigate the prevalence and correlates of preclinical atherosclerosis in patients with RA and SLE.
• To assess carotid plaque using ultrasonography as a measure of systemic atherosclerosis.
• To determine if inflammation associated with RA and SLE contributes to accelerated atherosclerosis.

Main Methods:

• Carotid ultrasonography was employed to examine patients with RA and SLE.
• Prevalence of carotid plaque was compared between patients and age- and sex-matched controls.
• Correlates of carotid atherosclerosis, including disease duration and damage, were analyzed.

Main Results:

• A significantly higher prevalence of carotid plaque was observed in RA and SLE patients compared to controls.
• This increased prevalence persisted after adjusting for traditional cardiovascular risk factors.
• Carotid atherosclerosis was associated with longer disease duration in both RA and SLE, and with disease damage in SLE.

Conclusions:

• Inflammation inherent to RA and SLE contributes to accelerated atherosclerosis.
• Carotid plaque is a marker of systemic atherosclerosis in these autoimmune diseases.
• More aggressive management of RA and SLE disease activity is warranted to mitigate cardiovascular risk.
