Introduction
Serum concentrations of adhesion molecules may be connected to the pathogenesis of secondary brain injury after spontaneous intracerebral hemorrhage (ICH). This study posits the hypothesis that levels of adhesion molecules substantially increase after ICH and are decreased thereafter, and that they can predict treatment outcomes.
Methods
Two hundred and thirty-nine blood samples were collected from 60 consecutive patients admitted within 24 hours after onset of spontaneous ICH and 60 blood samples were collected from 60 volunteers. Additional samples were obtained on Days 4, 7, 10, and 14 after onset of ICH regardless of clinical deterioration.
Results
Upon discharge, the therapeutic outcomes of the 60 spontaneous ICH cases based on the modified Rankin Disability Scale (mMRS) showed that 17 had no disability while 8.3% developed delayed cerebral infarction (DCI). Statistical analysis of adhesion molecules between patient groups with good outcome (mMRS = 0 or 1) and poor outcome (mMRS ≥2) revealed significant differences in diabetes mellitus (P=0.049), hyperlipidemia (P=0.012), mentality change (P=0.043), ICH volume and intraventricular hemorrhage on admission (P=0.036 and 0.006, respectively), Glasgow Coma Scale (GCS) on admission (P≤0.001), neuro-surgical intervention (P=0.003), and sE-selectin and soluble intercellular cell adhesion-molecule-1 (sICAM-1) levels on admission (P=0.036 and 0.019, respectively). Multiple logistic regression analysis of these significant variables showed that GCS on admission, hyperlipidemia, and sICAM-1 (P=0.039, 0.042, and 0.022, respectively) were independently associated with outcome of acute spontaneous ICH.
Conclusion
Increased sICAM-1 and sE-selectin levels may imply poor therapeutic outcomes for the treatment of spontaneous ICH during hospitalization. These early inflammatory responses may cause whole-brain injury immediately after spontaneous ICH and offer a potential therapeutic target for such patients. The importance of these findings is that they offer a potential therapeutic target for patients with spontaneous ICH.
