N-glycome profile levels relate to silent brain infarcts in a cohort of hypertensives

Background: Silent brain infarcts (SBIs) are highly prevalent in the aged population and relate to the occurrence of further stroke and dementia. Serum N-glycome levels have been previously associated with aging and they might be related as well to the presence of SBIs and age-related white matter hyperintensities. Methods and Results: We determined the serum N-glycome profile in a cohort study comprising 972 subjects and evaluated the relationship between N-glycome levels and the presence and number of SBIs and with age-related white matter hyperintensities grades, assessed by brain magnetic resonance imaging. Decreasing concentrations of bigalacto core-alpha-1,6-fucosylated biantennary glycan and increasing concentrations of branching alpha-1,3-fucosylated triantennary glycan remained as independent predictors of SBIs (odds ratio 0.4, 95% CI 0.3-0.7 and odds ratio 1.8, 95% CI 1-3.2, respectively), after controlling for the presence of age and classic vascular risk factors. A similar pattern was found to be related to an increasing number of SBIs and white matter hyperintensities grade. Conclusions: N-glycome levels might be potentially useful as biomarkers for the presence of silent cerebrovascular disease.
