Background: Stroke is a leading cause of long-term morbidity and mortality affecting several hundred-thousand people annually in the Western Countries. Various panels of biomarkers of neural damage have been developed and validated. The primary objective of this investigation was to measure the correlation between the clinical severity of stroke and the serum/plasma concentrations of neural damage biomarkers.
Methods: A prospective investigation was conducted on a panel of biomarkers composed of S100β, matrix metalloproteinase-9 (MMP-9), N-terminal pro-B-type natriuretic peptide (NT pro-BNP) and D-dimer at admission and after 24 hours, in a cohort patients with a confirmed diagnosis of stroke in an emergency setting (STROke-MArkers STROMA).
Results: A total of 58 consecutive patients were enrolled, no participant was excluded; according to clinical severity measured by National Institute of Health Stroke Scale (NIHSS) there were 29 minor strokes, 24 moderate, 3 moderate-severe, 2 severe. The Spearman’s rank correlation test was used to assess the relationship between the baseline NIHSS value and the concentrations of the four biomarkers: all the studied biomarkers showed a statistically significant correlation with baseline NIHSS at 24 hours. A multivariate ordinal regression model was used to analyze the correlation of markers with stroke severity, stratified, according to NIHSS score: MMP-9 and S100β showed a statistically significant correlation after 24 hours.
Conclusion: MMP-9, S100β, NT pro-BNP and D-dimer showed a good correlation with the clinical severity of stroke which may become an additional resource in the acute patient evaluation and potentially follow-up.
