- Brief Summary
The investigators hypothesize that low-dose dietary supplementation with omega-3 fish oil will improve disease activity and endothelial function in Systemic Lupus Erythematosus (SLE) patients.
- Detailed Description
Patients with SLE have a fifty-fold increased risk of myocardial infarction. This risk is not totally explained by traditional cardiovascular risk factors. In a previous double-blind study of atorvastatin in SLE, there was no reduction in surrogate measures of coronary artery disease (coronary calcium, coronary IMT, carotid plaque) and no effect on inflammatory markers such as ICAM, VCAM, IL-6 and CRP. We need to find novel approaches to reduce coronary artery disease in SLE. In a preliminary study, omega-3 was shown to improve flow mediated dilation of the brachial artery, oxidative stress and disease activity in lupus patients. In this study we will determine if omega-3 improves brachial artery flow dilation, disease activity and other vascular inflammatory markers (IL-6, s-VCAM-1, s-ICAM-1) in SLE, in a double-blind placebo-controlled trial.

Group Intervention Description Omega-3 flow-mediated dilation of the brachial artery 3 g of Omega-3 (1.8 g eicosapentaenoic acid, 1.2 g docosahexaenoic acid ethyl esters); flow-mediated dilation of the brachial artery corn starch flow-mediated dilation of the brachial artery corn starch; flow-mediated dilation of the brachial artery corn starch corn starch corn starch; flow-mediated dilation of the brachial artery Omega-3 Omega-3 3 g of Omega-3 (1.8 g eicosapentaenoic acid, 1.2 g docosahexaenoic acid ethyl esters); flow-mediated dilation of the brachial artery
- Primary Outcome Measures
Name Time Method Effect on Brachial Artery Flow Dilation by Omega-3 Versus Placebo. 12 weeks The assessment measured mean brachial artery diameter at pre-treatment(baseline) and post-treatment (after 12 weeks).
- Secondary Outcome Measures
Name Time Method Effect of Omega-3 Versus Placebo on Disease Activity in SLE. pre-treatment(baseline) and post-treatment (after 12 weeks) The assessment measured change in disease activities using SELENA-SLEDAI (Systemic Lupus Erythematosus Disease Activity Index Selena Modification - range 0-105) and PGA (Physician Global Assessment - range 0-3) comparing pre-treatment(baseline) vs post-treatment (after 12 weeks).
SELENA-SLEDAI - range 0-105, high score indicates high disease activity - weighted sum of sub-scale is used as total score.
PGA - range 0-3, high score indicates high disease activity.Effect on Markers of Inflammation: ICAM and VCAM by Omega-3 Versus Placebo. pre-treatment(baseline) and post-treatment (after 12 weeks) The inflammatory markers (sICAM-1 and sVCAM-1) were assessed and compared before and after treatment. change from baseline were reported.
