Abstract

Background and Purpose—: Subcortical ischemic vascular disease (SIVD) is a major form of vascular cognitive impairment (VCI) due to small vessel disease. Matrix metalloproteinases (MMPs) are neutral proteases that disrupt the blood–brain barrier and degrade myelin basic protein under conditions of neuroinflammation. Brain tissues and cerebrospinal fluid (CSF) of patients with VCI have increased levels of MMPs. We hypothesized that patients with SIVD have increased MMPs in the CSF, which are associated with increased CSF albumin. Methods—: We studied 60 patients with suspected VCI. Twenty-five were classified as SIVD, whereas other groups included mixed Alzheimer disease and VCI, multiple strokes, and leukoaraiosis when white matter lesions were present and the diagnosis of VCI was uncertain. MMP-2 and MMP-9 in CSF and plasma were measured by gel zymography and indexed to CSF and plasma albumin. MMP-3 activity was measured by fluorescent assay. Results—: We found reduced MMP-2 index ( P <0.001) in the CSF for the full group of patients (SIVD, multiple strokes, mixed Alzheimer disease and VCI, and leukoaraiosis) compared with control subjects, whose CSF was obtained during spinal anesthesia. MMP-3 activity was increased in VCI compared with control subjects ( P <0.01). In SIVD, MMP-2 index showed a negative correlation with albumin index, which was absent with the MMP-9 index. Combining MMP-2 index and MMP-3 activity separated the patients with SIVD from the control subjects with high specificity ( P <0.0005). Conclusions—: Our results support the hypothesis that MMPs are associated with increased CSF albumin and suggest that they may contribute to the pathophysiology of SIVD.

  • Plasma albumin is increased in the cerebrospinal fluid of patients with vascular cognitive impairment, reflecting blood-brain barrier breakdown.

    “First, the plasma protein albumin is increased in the CSF of patient with VCI, reflecting BBB breakdown (Candelario-Jalil et al., 2011).”

  • In a similar model, blood-brain barrier alteration was due to MMP9 production by oligodendrocyte precursors, which are increased in ischemic white matter injury in rodents and in patients with vascular cognitive impairment.

    “In a similar model, the BBB alteration was found to be due to MMP9 production by oligodendrocyte precursors, which are increased in ischemic white matter injury in rodent models (Seo et al., 2013) and in patients with VCI (Candelario-Jalil et al., 2011).”

    From The Pathobiology of Vascular Dementia (2013) · cites this paper as Candelario-Jalil et al., 2011

  • Pathological studies show markers of oxidative stress and inflammation in damaged white matter associated with vascular cognitive impairment.

    “Pathological studies have shown markers of oxidative stress (isoprostanes) and inflammation (cytokines and adhesion molecules) in the damaged white matter associated with VCI (Back et al., 2011; Candelario-Jalil et al., 2011; Fernando et al., 2006).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
