Abstract

Background —Asymmetric dimethylarginine (ADMA) is an endogenous competitive inhibitor of nitric oxide (NO) synthase. Because endothelial NO elaboration is impaired in hypercholesterolemia, we investigated whether plasma concentrations of ADMA are elevated in young, clinically asymptomatic hypercholesterolemic adults. We further studied whether such elevation of ADMA levels was correlated with impaired endothelium-dependent, NO-mediated vasodilation and urinary nitrate excretion. In a randomized, double-blind, placebo-controlled study, we investigated whether these changes could be reversed with exogenous l -arginine. Methods and Results —We measured plasma levels of l -arginine, ADMA, and symmetrical dimethylarginine (SDMA) by high-performance liquid chromatography in 49 hypercholesterolemic (HC) and 31 normocholesterolemic (NC) humans. In 8 HC subjects, endothelium-dependent forearm vasodilation was assessed before and after an intravenous infusion of l -arginine or placebo and compared with 8 NC control subjects. ADMA levels were significantly elevated by >100% (2.17±0.15 versus 1.03±0.09 μmol/L; P <0.05) in HC subjects compared with NC adults. l -Arginine levels were similar, resulting in a significantly decreased l -arginine/ADMA ratio in HC subjects (27.7±2.4 versus 55.7±5.4; P <0.05). In 8 HC subjects, intravenous infusion of l -arginine significantly increased the l -arginine/ADMA ratio and normalized endothelium-dependent vasodilation and urinary nitrate excretion. ADMA levels were inversely correlated with endothelium-mediated vasodilation ( R =0.762, P <0.01) and urinary nitrate excretion rates ( R =0.534, P <0.01). Conclusions —We find that ADMA is elevated in young HC individuals. Elevation of ADMA is associated with impaired endothelium-dependent vasodilation and reduced urinary nitrate excretion. This abnormality is reversed by administration of l -arginine. ADMA may be a novel risk factor for endothelial dysfunction in humans.

  • Individuals with atherosclerosis, chronic heart failure, hypertension, hypercholesterolemia, and diabetes mellitus, as well as women with PCOS, exhibit elevated levels of ADMA.

    “Studies have demonstrated that individuals with atherosclerosis, chronic heart failure [16, 17], hypertension [18], hypercholesterolemia [19], and diabetes mellitus [20], as well as women with PCOS [21], exhibit elevated levels of ADMA [22].”

    The Baseline Plasma L-Arginine and Dimethylarginine Concentrations section (page unavailable) reports significantly higher ADMA in hypercholesterolemic subjects than in controls. The Subjects section says participants had no signs of atherosclerotic vascular disease and that those with diabetes were excluded. The Discussion mentions a correlation with peripheral arterial disease severity, but the copy does not establish elevated ADMA across the other listed conditions or in women with PCOS.

  • Availability of l-arginine may be jeopardized under endothelial dysfunction, and concentrations of inhibitory l-arginine metabolites such as ADMA can increase in pathological conditions.

    “Several lines of evidence indicate that the availability of l-arginine may be jeopardized under endothelial dysfunction, and the concentrations of inhibitory l-arginine metabolites, such as ADMA, can also increase in pathological conditions (107, 1053).”

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.
