Effects of combined administration of vitamins C and E on reactive hyperemia and inflammatory process in chronic smokers

Tousoulis, D·2003·Atherosclerosis

Abstract

Purpose of this study was to investigate the effect of combined administration of antioxidant vitamins C and E on endothelial function and serum levels of inflammatory markers such as tumor necrosis factor alpha (TNF-alpha), interleukines 1b (IL-1b) and 6 (IL-6), vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1) and E-selectin in chronic smokers. Forty-three smokers were randomly divided into four groups receiving vitamin C 2 g/day (group A), vitamin C 2 g/day plus vitamin E 400 IU/day (group B), vitamin C 2 g/day plus vitamin E 800 IU/day (group C) or no antioxidant treatment (group D), for 4 weeks. Forearm blood flow (FBF) was measured using venous occlusion strain gauge plethysmography. Forearm vasodilatory response to reactive hyperemia (RH%) was expressed as the percentage change from baseline to post reactive hyperemia blood flow. RH% was significantly increased in groups B (P<0.05) and C (P<0.01), but remained unaffected in groups A and D. Serum levels of IL-1b, IL-6, sVCAM-1 and sICAM-1 were significantly reduced in group C (P<0.05, respectively), but remained unaffected in groups A, B and D. Thus, short term administration of vitamins C (2 g/day) and E (800 IU/day) reduces serum levels of IL-1b, IL-6, sVCAM-1 and sICAM-1, and improves forearm vasodilatory response to reactive hyperemia in healthy young smokers, while monotherapy with vitamin C alone is ineffective.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Several training interventions did not change basal IL-6 or CRP concentrations.

    “Several training interventions have not produced changes in basal IL-6 or CRP concentrations (213 -218) , while significant reductions in inflammatory markers have been observed following training without changes in BMI or body fat in elderly participants (219,220) .”

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.
