Increased CSF biomarkers of angiogenesis in Parkinson disease

Open access

Abstract

OBJECTIVE: To study biomarkers of angiogenesis in Parkinson disease (PD), and how these are associated with clinical characteristics, blood-brain barrier (BBB) permeability, and cerebrovascular disease. METHODS: In this cross-sectional analysis, 38 elderly controls and 100 patients with PD (82 without dementia and 18 with dementia) were included from the prospective Swedish BioFinder study. CSF samples were analyzed for the angiogenesis biomarkers vascular endothelial growth factor (VEGF); its receptors, VEGFR-1 and VEGFR-2; placental growth factor (PlGF); angiopoietin 2 (Ang2); and interleukin-8. BBB permeability, white matter lesions (WMLs), and cerebral microbleeds (CMB) were assessed. CSF angiogenesis biomarkers were also measured in 2 validation cohorts: (1) 64 controls and 87 patients with PD with dementia; and (2) 35 controls and 93 patients with neuropathologically confirmed diagnosis of PD with and without dementia. RESULTS: Patients with PD without dementia displayed higher CSF levels of VEGF, PlGF, and sVEGFR-2, and lower levels of Ang2, compared to controls. Similar alterations in VEGF, PlGF, and Ang2 levels were observed in patients with PD with dementia. Angiogenesis markers were associated with gait difficulties and orthostatic hypotension as well as with more pronounced BBB permeability, WMLs, and CMB. Moreover, higher levels of VEGF and PlGF levels were associated with increased CSF levels of neurofilament light (a marker of neurodegeneration) and monocyte chemotactic protein-1 (a marker of glial activation). The main results were validated in the 2 additional cohorts. CONCLUSIONS: CSF biomarkers of angiogenesis are increased in PD, and they are associated with gait difficulties, BBB dysfunction, WMLs, and CMB. Abnormal angiogenesis may be important in PD pathogenesis and contribute to dopa-resistant symptoms.

Figures

Figure 1 Angiogenesis biomarkers in CSF of healthy controls, PDND, and PDD patients (cohort 1) Vascular endothelial growth factor (VEGF) (A), placental growth factor (PlGF) (B), sVEGFR-2 (C), angiopoietin 2 (Ang2) (D), VEGF/sVEGFR-1 ratio (E), and PlGF/sVEGFR-1 ratio (F) are altered in patients with Parkinson disease without dementia (PDND) and patients with Parkinson disease with dementia (PDD) compared to controls. Angiogenesis biomarkers were skewed and therefore ln-transformed before statistical analyses; p values are from analysis of covariance adjusting for age and sex as described in the Methods; data are presented as mean ± 95% confidence interval.

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.
