Antibodies against oxidized LDL and atherosclerosis in rheumatoid arthritis patients treated with biological agents: a prospective controlled study
Abstract
Objectives: The aim of this study was to investigate the relation among atherosclerosis, antibodies against oxidized LDL (anti-oxLDL), and inflammation in rheumatoid arthritis (RA) patients treated with biological (b) disease-modifying anti-rheumatic drugs (DMARDs).
Methods: Fifty-nine patients who were receiving conventional synthetic DMARDs and were eligible for treatment with a biological agent were included in the study. Total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and IgG antibodies against oxidized LDL (anti-oxLDL) as well as carotid intima-media thickness (cIMT) were determined before and after 6 months of treatment. Thirty-one healthy individuals were used as a control group.
Results: At baseline, RA patients had lower TC and HDL-C levels and increased cIMT compared to controls. After a 6-month follow-up, the re-evaluation of carotids revealed a statistically important decrease of cIMT values. This observation was accompanied by a statistically important elevation of HDL-C levels and a reduction of the titer of anti-oxLDL antibodies regardless of the bDMARD that was administered. No statistically significant association was found between the cIMT and anti-oxLDL, HDL-C, CRP, or DAS28 score neither before nor 6 months after treatment using linear regression analyses adjusted for age and gender.
Conclusions: We provide evidence that atherogenic lipid profile and ongoing atherosclerosis which characterize RA patients appear to improve after biological therapy, and we also suggest a possible atherogenic effect of IgG anti-ox LDL antibodies.
