Abstract

Background Apolipoprotein (apo) distribution and lipoprotein (Lp)-associated markers of inflammation, such as lipoprotein-associated phospholipase A2 (Lp-PLA2), influence the atherogenicity of circulating lipids and lipoproteins. Little evidence exists regarding the dose-response effects of the marine omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on apos, apo-defined Lps, and Lp-PLA2.Objective The purpose of this study was to compare the effects of 0, 0.85, and 3.4 g/d of EPA + DHA on Lp-PLA2 mass and activity in individuals with moderate hypertriglyceridemia. We also measured effects on concentrations of apoAI, apoAII, apoB, apoC, apoD, and apoE-defined Lp subclasses.Methods The study was a randomized, doubleblind, crossover design with 8-week treatment periods and 6-week washout periods. During the 3 treatment periods, subjects (n = 25) received 0 g/d EPA + DHA, 0.85 g/d EPA + DHA (low dose), and 3.4 g/d EPA + DHA (high dose) in random order.Results apoB and apoC-III were significantly decreased by the high dose relative to placebo and low dose (P < .01), as was very low-density lipoprotein cholesterol (P < .005). The low dose had no effect on Lp outcomes compared with placebo. The high- and low-dose effects differed significantly for heparin-precipitated apoC-III, LpB, LpA-I, and apoB/apoA-I ratio (P < .05). There was a trend for a decreased Lp-PLA2 mass with the high dose (P = .1).Conclusion The effects of 3.4 g/d EPA + DHA on apoB and apoC-III may reduce atherosclerotic plaque progression in individuals with elevated triglycerides.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
