ABSTRACT

Objective To investigate the correlation betw een serum 25-hydroxyvitamin D (25(OH) D) level and enlarged perivascular spaces (EPVS) in patients w ith lacunar infarction. Methods Consecutive inpatients w ith acute lacunar infarction w ere enrolled. Chemiluminescence immunoassay w as used to measure the serum 25(OH)D. Head MRI w as used to assess the severity of EPVS in the centrum ovale and the basal ganglia region (grade 1, 0-10; grade 2, 11-25; grade 3, >25). Univariate analysis w as used to analyze the differences in baseline data among the three groups. Multivariate ordinal logistic regression analysis w as used to investigate the independent correlation betw een the 25(OH)D levels and the severity of EPVS. Results A total of 194 patients w ere enrolled,96 w ere males.Their mean age w as 63.4 ±9.3 years. The mean baseline National Institutes of Health Stroke Scale (NIHSS) score w as 2.0 ±1.7. The mean 25(OH)D level w as(50.25 ±15.50)nmol/L. There w ere 112 patients (57.7%), 45 (23.2%) and 37 (19.1%) w ith EPVS grade 1,grade 2 and grade 3 in the centrum ovale,and 109 (56.2%),53(27.3%) and 32 (16.5%) w ith EPVS grade 1, grade 2 and grade 3 in basal ganglia region, respectively. Multivariate ordinal logistic regression analysis show ed that serum 25(OH)D levels w ere independently associated w ith the severity of EPVS in the centrum ovale (odds ratio 2.898,95% confidence interval 1.345-9.612; P=0.028) and basal ganglia region (odds ratio 2.688, 95% confidence interval 1.182-10.281; P=0.039). Conclusion The low serum 25 (OH) D levels are independently associated w ith the severity of EPVS in patients w ith lacunar infarction.
