AbstractLipid abnormalities are an important cause of premature atherosclerosis in patients with systemic lupus erythematosus (SLE). This longitudinal study investigates the changes in lipid profile and arterial stiffness with SLE disease activity index (SLEDAI) reduction.Fifty one female SLE patients with baseline SLEDAI ≥ 6 and SLEDAI reduction >3 at 1-year follow-up were included. Neutrophil-to-lymphocyte ratio (NLR), erythrocyte sedimentation rate (ESR), high-sensitivity C-reactive protein (hsCRP), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglyceride (TG), and mean brachial-ankle pulse wave velocity (baPWV) were measured and compared between baseline and 1-year follow-up. Correlations between inflammation biomarkers, SLEDAI, mean baPWV and lipid profile were assessed.We observed significant decreases in ESR, mean baPWV, TG and TC to HDL-C ratio compared with baseline at 1-year follow up, while HDL-C, hsCRP, and NLR were not significantly changed. Significant correlations were found between the reductions in ESR and TG, and SLEDAI and mean baPWV, with adjustment to age, disease duration, blood pressure, and medications (prednisone, immunosuppressants and ARB/ACEI).SLE patients experiencing SLEDAI reductions showed improvements in arterial stiffness. This finding may provide insight into the beneficial effects of reducing SLEDAI on atherosclerosis risk in SLE.
