Background Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited cerebral microangiopathy presenting with variable features, including migraine, psychiatric disorders, stroke, and cognitive decline and variable disability. On neuroimaging, CADASIL is characterized by leukoencephalopathy, multiple lacunar infarcts, and microbleeds. Previous studies suggest a possible role of endothelial impairment in the pathogenesis of the disease. Methods We assessed plasma levels of von Willebrand factor (vWF) and thrombomodulin (TM) and the blood levels of endothelial progenitor cells (EPCs) and circulating progenitor cells (CPCs) in 49 CADASIL patients and 49 age-matched controls and their association with clinical/functional and neuroimaging features. Results In multivariate analysis, CADASIL patients had significantly higher vWF and lower EPC levels. TM levels were similar in the 2 groups. CADASIL patients with a more severe clinical phenotype (history of stroke or dementia) presented lower CPC levels in comparison with patients with a milder phenotype. On correlation analysis, lower CPC levels were associated with worse performances on neuropsychological, motor and functional tests, and with higher lesion load on brain magnetic resonance imaging (degree of leukoencephalopathy and number of lacunar infarcts). Conclusions This is the first CADASIL series in which multiple circulating biomarkers have been studied. Our findings support previous studies on the presence and the possible modulating effect of endothelial impairment in the disease. Furthermore, our research data suggest that blood CPCs may be markers of disease severity.

Abstract

Background Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited cerebral microangiopathy presenting with variable features, including migraine, psychiatric disorders, stroke, and cognitive decline and variable disability. On neuroimaging, CADASIL is characterized by leukoencephalopathy, multiple lacunar infarcts, and microbleeds. Previous studies suggest a possible role of endothelial impairment in the pathogenesis of the disease. Methods We assessed plasma levels of von Willebrand factor (vWF) and thrombomodulin (TM) and the blood levels of endothelial progenitor cells (EPCs) and circulating progenitor cells (CPCs) in 49 CADASIL patients and 49 age-matched controls and their association with clinical/functional and neuroimaging features. Results In multivariate analysis, CADASIL patients had significantly higher vWF and lower EPC levels. TM levels were similar in the 2 groups. CADASIL patients with a more severe clinical phenotype (history of stroke or dementia) presented lower CPC levels in comparison with patients with a milder phenotype. On correlation analysis, lower CPC levels were associated with worse performances on neuropsychological, motor and functional tests, and with higher lesion load on brain magnetic resonance imaging (degree of leukoencephalopathy and number of lacunar infarcts). Conclusions This is the first CADASIL series in which multiple circulating biomarkers have been studied. Our findings support previous studies on the presence and the possible modulating effect of endothelial impairment in the disease. Furthermore, our research data suggest that blood CPCs may be markers of disease severity.
