Atherosclerosis Prevention in Pediatric Lupus Erythematosus (APPLE)

The purpose of this study is:

1. To assess the efficacy of a lipid-lowering agent (atorvastatin) on the development of atherosclerosis that predisposes children with SLE to cardiovascular events in adulthood. 2. To assess the safety of intermediate-term (36 months) treatment of children and young adults with atorvastatin. 3. To further characterize the course of SLE in children and young adults, by establishing a cohort of pediatric SLE patients to be followed prospectively. 4. To establish a mechanism for conducting clinical trials in rare pediatric rheumatic diseases using the Children's Arthritis and Rheumatology Research Alliance (CARRA).

About this study

Children and adolescents with SLE represent 15% of all SLE patients. Children with SLE suffer high morbidity that affects many organ systems, reduces their quality of life, and shortens their lifespan. As more children with SLE survive into adulthood, atherosclerotic cardiovascular disease has emerged as a major concern. SLE is a significant risk factor for myocardial infarction and death in young premenopausal women with SLE, even after controlling for traditional cardiovascular risk factors. Acceleration of atherogenesis in SLE most likely reflects SLE-associated vascular immune and inflammatory changes.

Although limited, the data on cardiovascular and lipid abnormalities in children with SLE implicate atherosclerosis as an important cause of long-term morbidity and mortality. The 3-hydroxy-3-methlglutaryl-coenzyme A (HMG CoA) reductase inhibitors, or statins, reduce mortality and morbidity from atherosclerosis in adults and have intrinsic anti-inflammatory and immune modulatory properties. These anti-inflammatory and immune modulatory activities may have particular benefit in the prevention and treatment of atherosclerosis in SLE. This trial will evaluate atorvastatin in children with SLE in the largest cohort of pediatric SLE patients ever studied prospectively.

Children in this study will be randomized to receive either atorvastatin or a placebo. All children will be followed for 3 years, during which they will have 15 study visits. Study visits will generally last 2 hours and will include medical interview, medication review and pill count, physical examination, and blood and urine tests. Cardiovascular-specific outcome measures will include assessments of high sensitivity CRP; fasting lipid profile; homocysteine level; apolipoprotein A, B1, and Lp(a); carotid intima media thickness (IMT); and tensor diffusion/MRI.

Primary outcomes

  1. Change in Mean-Mean Common Carotid IMT (CIMT)

    Time frame: Change from baseline to 36 months

    For the common carotid arterial segment, mean CIMT values were averaged across angles by side and wall to produce 4 summary variables (right common near wall mean, right common far wall mean, left common near wall mean and left common far wall mean). These summary variables were then averaged to estimate a single mean-mean common CIMT for each participant visit.

Secondary outcomes

  1. Change in Mean-Max CIMT

    Time frame: Change from baseline to 36 months

    For each side, segment and wall, the maximum CIMT over the 4 angles of interrogation was selected to produce 12 summary variables (right common near wall max, right common far wall max, right bifurcation near wall max, right bifurcation far wall max, right internal near wall max, right internal far wall max, left common near wall max, left common far wall max, left bifurcation near wall max, left bifurcation far wall max, left internal near wall max and left internal far wall max). These 12 summary variables were then averaged to estimate a single mean-max CIMT for each participant visit.

  2. Change in Mean-Mean CIMT

    Time frame: Change from baseline to 36 months

    For each side, segment and wall, mean CIMT values were averaged over the 4 angles of interrogation to produce 12 summary variables (right common near wall mean, right common far wall mean, right bifurcation near wall mean, right bifurcation far wall mean, right internal near wall mean, right internal far wall mean, left common near wall mean, left common far wall mean, left bifurcation near wall mean, left bifurcation far wall mean, left internal near wall mean and left internal far wall mean). These 12 summary variables were then averaged to estimate a single mean-mean CIMT for each participant visit.

  3. Change in Mean-Max Common CIMT

    Time frame: Change from baseline to 36 months

    For each side and wall of the common carotid arterial segment, the maximum CIMT over the 4 angles of interrogation was selected to produce 4 summary variables (right common near wall max, right common far wall max, left common near wall max and left common far wall max).

  5. Change in Mean-Mean Internal CIMT

    Time frame: Change from baseline to 36 months

    For the internal carotid arterial segment, mean CIMT values were averaged across angles by side and wall to produce 4 summary variables (right internal near wall mean, right internal far wall mean, left internal near wall mean and left internal far wall mean).
