Xanthine Oxidase Inhibition For The Treatment Of Cardiovascular Disease: A Systematic Review and Meta‐Analysis
Open accessAbstract
Summary: Background: Xanthine oxidase inhibition (XOI) reduces oxidative stress in the vasculature. Moreover it reduces uric acid levels, a risk factor for the development of cardiovascular disease. As such, XOI holds a potentially dual mechanism for the treatment of cardiovascular disease. Aims: Through systematic review, we sought to clarify the extent of available evidence that has evaluated the effect of XOI upon clinical or surrogate markers of cardiovascular disease and function in humans. Methods: A systematic search strategy was used to interrogate the Ovid Medline (1950–June Week 4 2010) and Embase (1980–2010 Week 25) databases, to identify relevant studies. Meta‐analysis was planned for frequently studied endpoints. Results: Thirty‐eight publications (reporting 40 studies) were identified. There was heterogeneity between studies in all aspects of study design, including the outcome measures of interest. Prospective assessment of surrogate markers predominated. Combined meta‐analysis was feasible for three outcome parameters, with favorable modifications in each following xanthine oxidase inhibition: brachial artery flow mediated dilatation (five studies: XOI n = 75, control n = 69) increased by 2.50% (95% CI, 0.15–4.84); forearm blood flow responses to acetylcholine infusion (five studies: XOI n = 74, control n = 74) increased by 68.80 (95% CI, 18.70–118.90; percent change relative to noninfused control arm); circulating markers of oxidative stress (malondialdehyde, six studies: XOI n = 78, control n = 68) reduced by 0.56 nmol/mL (95% CI, 0.26–0.87). Conclusions: XOI improves endothelial function and circulating markers of oxidative stress in patients with, or at risk of, cardiovascular disease. Large prospective studies examining definitive end points are lacking but now appear indicated.

Meta-analysis of available studies indicates some improvement of cardiovascular function with allopurinol/oxypurinol.
“Despite these initial results, subsequent trials with larger number of patients have failed to report substantial positive effects as compared with the placebo groups (361, 405), although the meta-analysis of available studies indicates some improvement of cardiovascular function (430).”

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.
