  • Serum HDL Level [ Time Frame: 12 weeks ]
  • Brachial Artery Reactivity [ Time Frame: 12 weeks ]

    To demonstrate the impact of omega-three fatty acid intake on BART (Brachial Artery Reactivity Test) at 12 weeks.

    Brachial artery ultrasound measurements Brachial artery reactivity will be assessed by ultrasound and FMD will be calculated as the change in brachial artery diameter after release of suprasystolic blood pressure cuff inflation. A blood pressure cuff will be inflated on the upper arm to induce increase in blood flow, termed reactive hyperemia, which increases arterial diameter. The change in vessel diameter is determined by high-resolution ultrasound imaging. The endothelium-dependent FMD of the brachial artery is quantified as the maximum percent change in arterial diameter, expressed in units of "% of brachial artery".

Human Immunodeficiency Virus (HIV), Arterial Dysfunction, Lipids, Lovaza (HALO) Trial
The purpose of this study is to determine whether fish oil supplementation with Lovaza, formally known as Omacor will result in a significant reduction in serum triglyceride (TG), an increase in high density lipoproteins(HDL), and an improvement of endothelial dysfunction.
This is a randomized, double blind, placebo controlled, cross-over, clinical trial to determine the effect of fish oil supplementation with Lovaza® on triglyceride levels in HIV-infected subjects on HAART with elevated serum triglycerides. The sample size is 40 subjects. The total duration of the study is 28 weeks, with 12-week treatment periods separated by a 4-week washout. This study will be conducted at the Clinical Research Center at Tufts Medical Center.
