Prevalence and factors associated with dyslipoproteinemias in Brazilian systemic lupus erythematosus patients.

To determine the prevalence of dyslipoproteinemias and their related factors in a Brazilian systemic lupus erythematosus (SLE) population, fasting lipids were measured in 185 female SLE outpatients. Age, BMI, smoking, post-menopausal status, presence of diabetes and hypertension, SLE duration, number of ARA criteria, drug treatment and disease activity (by SLEDAI) were registered. Statistics included uni and multivariate logistic regression. Eighty-nine patients (48.1%) had hypercholesterolemia, 55 (29.7%) had hypertriglyceridemia and 109 (58.9%) had either. On multivariate analysis, 24-h proteinuria (OR = 2.08, 95% CI: 1.11–3.88), BMI (OR = 1.08, 95% CI: 1.01–1.16) and post-menopausal status (OR = 2.48, 95% CI: 1.25–4.92) were associated with hypercholesterolemia. Disease activity was related to low HDL-cholesterol (OR = 2.59, 95% CI: 1.20–5.58) and, in pre-menopausal patients, also to hypertriglyceridemia (OR = 1.16, 95% CI: 1.03–1.30). Antimalarial use was protective for hypertriglyceridemia (OR = 0.44, 95% CI: 0.22–0.90). In conclusion, the increased prevalence of dyslipoproteinemias is due to proteinuria, obesity and SLE activity. Antimalarials have beneficial effect on lipid profile that may be due to reduction in disease activity. [ABSTRACT FROM AUTHOR]
