Level 4 - case-series / case-control
Cross-sectional observational study comparing circulating inflammatory markers with neuroimaging findings.

What was done
Researchers investigated whether circulating markers of endothelial activation (sICAM-1, sVCAM-1, sE-selectin, sP-selectin), monocyte/macrophage activation (neopterin), and systemic inflammation (CRP) associate with cerebral small vessel disease (CSVD) features on brain MRI. The cohort comprised 163 patients with first-ever lacunar stroke and 183 patients with essential hypertension.
What was found
Circulating neopterin, sICAM-1, and sVCAM-1 concentrations were significantly higher in patients with extensive CSVD manifestations compared to those without extensive manifestations (p < 0.01). Neopterin levels independently associated with higher counts of enlarged Virchow-Robin spaces (p < 0.001). Exact biomarker concentrations, effect sizes, and risk ratios were not reported in the abstract.
Why it matters
These findings suggest that endothelial activation and monocyte/macrophage-mediated inflammatory processes correlate with structural brain changes and potential blood-brain barrier dysfunction in cerebral small vessel disease.
Limits
The cross-sectional design cannot establish causality between inflammatory markers and CSVD progression. The abstract does not provide exact biomarker values, confidence intervals, or specific effect sizes, and the sample was restricted to lacunar stroke and hypertensive cohorts, limiting generalizability to wider populations.
