Atherosclerosis Prevention in Pediatric Lupus Erythematosus (APPLE)

2013年7月15日 更新者:Laura Schanberg

A Multicenter, Randomized, Double-Blind, Placebo-Controlled Study to Test the Safety and Efficacy of Lipitor (Atorvastatin) in Reducing the Progression of Carotid IMT in Early Childhood SLE

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).

研究概览

详细说明

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.

主要结果指标

结果测量
措施说明
大体时间
Change in Mean-Mean Common Carotid IMT (CIMT)
大体时间: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.
