title: Dyslipoproteinemia in systemic lupus erythematosus. Effect of corticosteroids.
abstract: The increased incidence of atherosclerotic coronary artery disease in patients with systemic lupus erythematosus (SLE) may be due to a dyslipoproteinemia caused by corticosteroid administration. To determine whether lipoprotein lipid levels are abnormal in SLE and the relation of lipoprotein levels to corticosteroid use, lipid and apolipoprotein levels were measured in 46 female patients with SLE and 30 matched control subjects. The patients with SLE had higher levels of plasma triglyceride (134 versus 73 mg/dl; p less than 0.001), cholesterol (201 versus 168 mg/dl; p less than 0.001), and low-density lipoprotein cholesterol (121 versus 94 mg/dl; p less than 0.001) than control subjects. The levels of high-density lipoprotein cholesterol, high-density lipoprotein subfraction 3 cholesterol, and apolipoprotein Al were similar in the two groups, but high-density lipoprotein subfraction 2 cholesterol was lower in the patients with SLE (10.2 versus 18.2 mg/dl; p less than 0.001). When patients with SLE treated with prednisone (n = 32) were compared to patients with SLE not treated with prednisone (n = 14), the former had higher triglyceride (158 versus 87 mg/dl; p less than 0.001), cholesterol (214 versus 170 mg/dl; p less than 0.001), and low-density lipoprotein cholesterol (130 versus 103 mg/dl; p less than 0.001) levels. The patients with SLE not treated with prednisone had lipid levels similar to those in control subjects except that high-density lipoprotein cholesterol was lower (49.7 versus 59.0 mg/dl; p less than 0.05). The daily prednisone dosage in the treated patients with SLE correlated with levels of cholesterol (r = 0.38, p less than 0.02), high-density lipoprotein cholesterol (r = 0.40, p less than 0.02), and high-density lipoprotein subfraction 3 cholesterol (r = 0.47, p less than 0.01). Thus, female patients with SLE have a dyslipoproteinemia of the type that would place them at an increased risk for coronary artery disease. Corticosteroids, used in the treatment of SLE, seem to play a role in the pathogenesis of the observed lipoprotein abnormalities.
