Summary
Elevated serum levels of interleukin-12 (IL-12) were observed in acute ischemic stroke patients compared to controls. These IL-12 levels correlated with stroke severity and inflammatory markers, suggesting a role in ischemic stroke.
Area of Science:
- Neuroscience
- Immunology
- Inflammation Research
Background:
- Cytokines mediate stroke-induced inflammation, impacting infarct progression, disease severity, and outcomes.
- Interleukin-12 (IL-12) is a key proinflammatory and immunomodulatory cytokine.
Purpose of the Study:
- To evaluate serum IL-12 levels in acute ischemic stroke patients.
- To investigate the relationship between IL-12 levels and demographic, laboratory, neuroimaging, and clinical data.
Main Methods:
- Serum IL-12, erythrocyte sedimentation rate (ESR), and leukocyte count were measured in 23 ischemic stroke patients and 15 controls within 24 hours of stroke onset.
- Cranial CT scans were performed to assess brain infarct volume.
- Neurological and functional deficits were evaluated using the Scandinavian Stroke Scale (SSS) and Barthel Index (BI).
Main Results:
- Stroke patients exhibited significantly higher serum IL-12 levels than controls.
- Serum IL-12 levels positively correlated with ESR values and the volume of hypodense areas on CT.
- IL-12 levels showed significant correlations with SSS and BI scores at both initial assessment and two-week follow-up.
Conclusions:
- The findings suggest that IL-12 may play a role in the pathophysiology of ischemic stroke.
- Elevated IL-12 levels are associated with stroke severity and inflammatory markers.
- Further research into IL-12's role could inform therapeutic strategies for ischemic stroke.
