Abstract: Objectives. Lipid profiles appear to be altered in SLE patients due to disease activity and inflammation.
Cholesterol efflux capacity (CEC) is the ability of high-density lipoprotein cholesterol to accept cholesterol from
macrophages. CEC has been linked to cardiovascular events in the general population and is impaired in SLE
patients. The aim of this study was to establish whether CEC is related to subclinical carotid atherosclerosis in
Methods. The present report is of a cross-sectional study that encompassed 418 individuals: 195 SLE patients
and 223 controls. CEC, using an in vitro assay, and lipoprotein serum concentrations were assessed in patients
and controls. Carotid intima-media thickness and carotid plaques were evaluated in SLE patients. A multivariable
analysis was performed to study the relationship of CEC to SLE-related data, lipid profile and subclinical carotid atherosclerosis.
Results. CEC was downregulated in SLE patients [8.1 (4.2) % vs 16.9 (10.4) %, P ¼ 0.004). This occurred independently
of traditional cardiovascular risk factors, statin use or other variations in the lipid profile related to the disease. Traditional cardiovascular risk factors, both in patients and controls, and SLE-related data such as activity, severity or damage were not associated with CEC. After multivariable regression analysis including lipid profile? related molecules, CEC was inversely and independently associated with the presence of carotid plaques in SLE patients [odds ratio 0.87 (95% CI: 0.78, 0.97), P ¼ 0.014].
Conclusion. CEC is impaired in SLE patients independently of other inflammation-related lipid profile modifications that occur during the disease. CEC is associated with carotid plaques in SLE patients
