N2 - Despite the increased prevalence of cardiovascular disease in patients with systemic lupus erythematosus (SLE), little is known about the role of high sensitivity C-reactive protein (hsCRP) or whether ethnicity, gender, anthropometric measures and treatment can alter hsCRP levels. We evaluated the effects of treatment and demographic, anthropometric and socio-economic variables on hsCRP levels in SLE. High sensitivity C-reactive protein levels were measured using an immunoturbidimetric assay in 610 patients from the Hopkins Lupus Cohort, who were followed-up regularly. In stepwise multiple regression analyses, body mass index (BMI) [odds ratio (OR) 1.72, 95% confidence interval (CI) 1.34-2.20, P < 0.001], African-American ethnicity (OR 1.97, 95% CI 1.22-3.19, P < 0.01), education (OR 0.60, 95% CI 0.42-0.86, P < 0.01), statin use (OR 0.38, 95% CI 0.18-0.82, P < 0.05), estrogen use (OR 3.65, 95% CI 1.19-11.22, P < 0.05), SLE Disease Activity Index score (OR 1.76, 95% CI 1.09-2.87, P < 0.05) and cumulative prednisone dose (OR 1.27, 95% CI 1.01-1.60, P < 0.05) were significant predictors of hsCRP levels. These findings suggest that hsCRP levels should be adjusted for BMI, ethnicity, education level, disease activity and medications when conducting cardiovascular risk assessment in patients with lupus.
