Abstract

Objective: Cerebral white matter lesions (WMLs) are radiologic markers of small vessel disease in brain, and inflammatory processes were related to WMLs. We propose to determine if elevated leukocyte count was associated with a higher risk of WMLs. Methods: 1586 asymptomatic subjects who visited our hospital for a routine health check-up were enrolled. Leukocyte counts were measured and the presence of moderate to severe WMLs was determined by brain MRI. Results: Thirty (1.9%) had moderate to severe WMLs, and a significant greater proportion (4.1%) of subjects in the highest leukocyte count quartile had moderate to severe WMLs. After adjusting by C-reactive protein, aspirin use and cardiovascular risk factors, the highest quartile of leukocyte count (≥6.7 × 10 9/L) was significantly associated with moderate to severe WMLs compared with the lowest quartile [adjusted odds ratio, 4.03; 95% confidence interval, 1.05-15.5]. Conclusion: The authors report for the first time that an elevated leukocyte count is independently associated with moderate to severe WMLs.
