OBJECTIVES: To investigate the prevalence of autoantibodies against ATP-binding cassette transporter A1 (ABCA1) in SLE patients, and evaluate the association between anti-ABCA1 autoantibodies and atherosclerosis in SLE. DESIGN AND METHOD: The sera of 75 SLE patients and 75 healthy controls were tested by immunoblotting. Then, we examined the effect of anti-ABCA1 autoantibodies on cholesterol efflux in vitro. RESULTS: The prevalence of anti-ABCA1 antibodies in SLE patients was significantly higher than the controls (p<0.05). The prevalence in the SLE-plaque group was higher than that in the SLE-non-plaque group (p<0.05). The IgG purified from anti-ABCA1-antibody positive sera can inhibit cellular cholesterol efflux from THP-1 cells in vitro with a significantly higher inhibition ratio than that of healthy controls. CONCLUSIONS: Our observations suggest that anti-ABCA1 autoantibodies are involved in the pathogenesis of lupus atherosclerosis and that autoantibodies against ABCA1 may act as biomarkers for atherosclerosis in SLE.
