Abstract

Objectives To determine the efficacy of 4 g/day fish oil to lower triglycerides and impact lipoprotein particles, inflammation, insulin resistance, coagulation, and thrombosis.Study design Participants (n = 42, age 14 ± 2 years) with hypertriglyceridemia and low-density lipoprotein (LDL) cholesterol <160 mg/dL were enrolled in a randomized, double-blind, crossover trial comparing 4 g of fish oil daily with placebo. Treatment interval was 8 weeks with a 4-week washout. Lipid profile, lipoprotein particle distribution and size, glucose, insulin, high-sensitivity C-reactive protein, interleukin-6, fibrinogen, plasminogen activator inhibitor-1, and thrombin generation were measured.Results Baseline lipid profile was total cholesterol 194 (5.4) mg/dL (mean [SE]), triglycerides 272 (21) mg/dL, high-density lipoprotein cholesterol 39 (1) mg/dL, and LDL cholesterol 112 (3.7) mg/dl. LDL particle number was 1614 (60) nmol/L, LDL size was 19.9 (1.4) nm, and large very low-density lipoprotein/chylomicron particle number was 9.6 (1.4) nmol/L. Triglycerides decreased on fish oil treatment but the difference was not significant compared with placebo (-52 ± 16 mg/dL vs -16 ± 16 mg/dL). Large very low-density lipoprotein particle number was reduced (-5.83 ± 1.29 nmol/L vs -0.96 ± 1.31 nmol/L; P < .0001). There was no change in LDL particle number or size. There was a trend towards a lower prothrombotic state (lower fibrinogen and plasminogen activator inhibitor-1; .10 > P > .05); no other group differences were seen.Conclusions In children, fish oil (4 g/day) lowers triglycerides slightly and may have an antithrombotic effect but has no effect on LDL particles.

  • Prescription doses of omega-3 fatty acids appear as safe for managing elevated triglycerides in adolescents and children as young as 10 years as for adults.

    “Prescription doses of n-3 FA appear to be as safe for the management of elevated triglycerides in adolescents and children as young as 10 years of age as they are for adults.78,79”

    From Omega-3 Fatty Acids for the Management of Hypertriglyceridemia: A Science Advisory From the American Heart Association (2019) · cites this paper as [79]

    The Methods section enrolled adolescents eligible from ages 10–17 with elevated triglycerides, and the Results section says 4 g/day fish oil was well tolerated, with medication-related adverse events that were mild to moderate. The paper does not compare safety with adults, and eligibility from age 10 does not establish that a 10-year-old participant received treatment. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Those pediatric trials used lower doses (less than 2 g/d EPA+DHA) or had small sample sizes (fewer than 20 participants per arm), sometimes including patients with only mildly elevated triglycerides.

    “However, these trials used lower doses (<2 g/d EPA+DHA) 81 or had relatively small sample sizes (<20 participants per study arm) 79,81 that in some cases included patients with only mildly elevated triglycerides.81”

    From Omega-3 Fatty Acids for the Management of Hypertriglyceridemia: A Science Advisory From the American Heart Association (2019) · cites this paper as [79]

    The Methods report 42 adolescents in a crossover trial, supporting the description of a relatively small study, but the available passages do not establish fewer than 20 participants per study arm. The Methods also specify at least 1.5 g DHA plus 1.86 g EPA daily—more than 2 g combined, contrary to the dose attributed to this trial. Enrollment allowed triglycerides from 150 mg/dL, but the Results describe the groups overall as having severely increased triglycerides; they do not establish that participants had only mildly elevated levels. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • The few studies of omega-3 fatty acid supplementation in children and adolescents with hypertriglyceridemia have not shown a significant triglyceride-lowering effect.

    “the few studies of n-3 FA supplementation in children/ adolescents with HTG have not shown a significant triglyceride-lowering effect.78,79,81”

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.
