Overview
Brief Summary
High triglyceride levels are increasingly recognized in children, particularly those who are overweight. There are no studies of treatment of high triglycerides in children and adolescents. Fish oil is attractive because it is considered safe and effective for treating high triglycerides in adults and has been used safely for other purposes in children. The investigators will conduct a randomized study of Lovaza (the only prescription omega-3 fish oil medication) in 44 children and adolescents to study efficacy in lowering triglycerides, safety, and possible mechanisms of beneficial effects.
Detailed Description
Participants (n = 42, age 14 + 2 yrs) with hypertriglyceridemia and LDL cholesterol \< 160 mg/dl were enrolled in a randomized double blind cross over trial comparing 4 g fish oil daily with placebo. Treatment interval was 8 weeks with a 4 week wash out, between the two treatment intervals. Lipid profile, lipoprotein particle distribution and size, glucose, insulin, high sensitivity C reactive protien (CRP), interleukin-6, fibrinogen, plasminogen activator inhibitor-1 (PAI-1), and thrombin generation were measured. Patients were evaluated at 6 time points: Visit 1/baseline (week 0), Visit 2/randomization (week 4), Visit 3/after treatment 1 (week 12) , Visit 4/after wash out (week 16), Visit 5/after treatment 2 (week 24) and Visit 6/close out (week 28) . Patients were advised to maintain a stable diet and not alter baseline fish consumption . One participant took an oral contraceptive throughout the trial. Any fish oil supplements were discontinued. Advice on a heart healthy diet was provided. Blood pressure (right arm sitting with appropriate sized cuff, taken 3 times, last measurement used), height, and weight were measured at the beginning of the study, after the first wash out period, and close out. Participant phone contact was made during each treatment arm to assess diet stability. Fasting lipid profile was performed at every visit. Red blood cell fatty acid profile and secondary endpoints were performed at all visits except baseline.

Arms & Interventions
Omega-3-acid ethyl esters (Lovaza)
This randomized, double-blind, placebo, crossover trial consisted of two 8-week treatment periods, separated by a 4-week washout. Eligible patients were randomized to receive either fish oil 4 g daily or corn oil placebo during the first 8-week treatment period; patients received the alternate treatment during the next treatment period. GlaxoSmithKline supplied the study drug and the placebo. The study drug, Omega-3-acid ethyl esters (Lovaza) was given to patients PO daily as two, 1 g capsules taken twice daily during the duration of their 8-week treatment period. The study drug contained minimally 1.5 g DHA (docosahexaenoic acid) and 1.86 g EPA (eicosapentaenoic acid).
Intervention: Omega-3-acid ethyl esters
Placebo
This randomized, double-blind, placebo, crossover trial consisted of two 8-week treatment periods, separated by a 4-week washout. Eligible patients were randomized to receive either fish oil 4 g daily or corn oil placebo during the first 8-week treatment period; patients received the alternate treatment during the next treatment period. The corn oil placebo was given to patients PO daily as two, 1 g capsules taken twice daily during the duration of their 8-week non-treatment (placebo) period.
Intervention: Placebo
