Background/Objective: The mechanisms explaining low cholesterol levels in chronic inflammatory rheumatic disease (CIRD) is incompletely understood. We hypothesized that chronic inflammation impairs the functionality of high-density lipoprotein (HDL) by oxidative processes. The role of oxidized HDL (HDLox) a marker of dysfunctional HDL, has not been studied to date. Therefore, we measured HDLox serum levels in patients first diagnosed with CIRD before and after the initiation of immunosuppressive therapy and to compare it with non-CIRD controls.

Methods: A total of 180 patients, 44 with newly diagnosed CIRD and 136 without CIRD as controls, were prospectively included in the study after informed consent. In CIRD patients, peripheral blood samples were drawn before (baseline) and 12 weeks after the initiation of immunosuppressive therapy. Lipid profiles including HDLox and C-reactive protein (CRP) serum levels were measured in both groups at baseline. Validated outcome tools for disease activity and function were assessed at baseline and after 12 weeks.

Results: A total of 33 patients with rheumatoid arthritis (RA, 75%), 7 with axial spondyloarthritis (16%), and 4 with systemic lupus erythematosus (9%) were included. Groups were comparable for gender, age, and BMI. CIRD patients had higher HDLox concentrations (1.57 vs. 0.78, p=0.02), and tended to have lower low-density lipoprotein cholesterol (LDL-C), HDL-cholesterol (HDL-C), and cholesterol levels compared to controls. HDLox (1.57 vs.1.4, p=0.26) and C-reactive protein levels (2.1 mg/dl vs. 0.7 mg/dl, p<0.01) decreased in CIRD patients from baseline to follow up.

Conclusion: CIRD is associated with an impairment of the anti-inflammatory properties of HDL-C as reflected by an increase in HDLox concentrations. This may contribute to the increased cardiovascular risk of these patients.
