Severity of stroke symptoms was assessed using the National Institutes of Health Stroke Scale (NIHSS), whereas functional outcome was assessed with modified Rankin Scale (mRS). The commercially available sets of enzymatic immune tests were used to estimate the concentrations of inflammatory markers in serum.Results: Medians of IL-6 serum concentrations prior to IV-thrombolysis were lower in patients with favorable (mRS 0– 2 pts) functional outcome than in those with unfavorable (mRS 3– 6 pts) functional outcome, both at hospital dismission (5.92: 2.30– 7.71 vs 9.46: 3.79– 17.29 pg/mL; p< 0.01) and on the ninetieth day from stroke onset (5.87: 2.30– 10.58 vs 10.9: 5.94– 17.28 pg/mL; p< 0.01). There were no existing differences regarding hsCRP levels between groups (2.49: 0.11– 9.82 vs 4.44: 0.32– 9.87 mg/dL; p=0.30 and 2.57: 0.11– 2.57 vs 2.83: 0.32– 9.32 mg/dL; p=0.75, respectively). Patients with lacunar strokes were characterized by lower median of IL-6 (5.96: 2.87– 13.0% vs 7.29: 2.30– 17.28; p=< 0.02) and hsCRP (2.25: 0.11– 9.82 vs 4.84: 0.35– 9.87; p=0.01) than those with nonlacunar infarctions. Multivariate analysis showed an impact of IL-6 on mRS measured on hospital dismission and after three months, regardless of their initial NIHSS, presence of hemorrhagic transformation and type 2 diabetes. No impact of hsCRP, lacunar etiology and patients’ age on functional outcome existed.Conclusion: Regardless of the stroke etiology, pretreatment of IL-6, but not of hsCRP levels, may help to predict functional outcome after IV-thrombolysis independently of symptom severity and stroke complications.Keywords: inflammatory markers, ischemic stroke, thrombolysis, old age diseases |
