The association of uric acid with leukoaraiosis

OBJECTIVE: To explore the possible correlation between uric acid levels and leukoaraiosis (LA). METHODS: This cross-sectional study enrolled patients who presented with some neurological discomfort (e.g. dizziness, headache, mild cognitive impairment). Potential demographic and clinical risk factors associated with LA, including sex, age, hypertension, diabetes mellitus, smoking, alcohol consumption, dyslipidaemia, plasma fibrinogen, D-dimer, uric acid, and homocysteine, were investigated using univariate and multivariate logistic regression analyses. RESULTS: A total of 268 patients were enrolled in the study and divided into the LA group (n = 164) and the non-LA group (n = 104). Compared with the non-LA group, uric acid was significantly higher in the LA group (mean ± SD: 356.49 ± 121.85 µmol/l versus 289.96 ± 102.98 µmol/l). Multivariate logistic regression analyses showed that uric acid was an independent risk factor for LA (odds ratio 1.285; 95% confidence interval 1.062, 1.556). CONCLUSION: Hyperuricaemia was an independent risk factor for leukoaraiosis in Chinese patients.
