    Higher Monocyte Count is Associated with 30-Day Case-Fatality in Intracerebral Hemorrhage

    Background: Previous studies have suggested that elevated neutrophils, monocytes, and neutrophil-to-lymphocyte ratio (NLR) may be associated with poor outcomes in intracerebral hemorrhage (ICH). We sought to determine whether white blood cell (WBC) types were independently associated with poor outcome in ICH in a large cohort. Methods: We performed a retrospective study of primary ICH at two academic centers. Cases were identified via ICD-9 code and verified via physician review. We included only those patients with WBC types obtained within 24 h of ICH onset. Results: We identified 593 patients with primary ICH and WBC differentials in the first 24 h. Independent factors (OR, 95% CI) associated with 30-day case fatality were age > 80 (2.4 (1.4, 4.2)), p = 0.0023; NIHSS greater than median (3.9 (2.4, 6.3)), p < 0.0001; ICH volume quartiles (Q1: ref, Q2: 1.5 (0.7, 3.0), Q3: 3.2 (1.6, 6.6), Q4: 11.9 (5.3, 26.4)), p < 0.0001; non-lobar location (3.3 (1.9, 5.9)), p ≤ 0.0001; IVH (2.3 (1.4, 3.6)), p = 0.0005, monocytes greater than median (1.6 (1.0, 2.4)), p = 0.0457, and anticoagulant use (3.2 (1.8, 5.6)), p < 0.0001. Elevated NLR was not associated with higher case fatality. Conclusions: We found that elevated monocytes were independently associated with 30-day case fatality. Future studies will investigate whether there are subgroups of ICH patients, including those with particular blood or imaging biomarkers, in which WBC types might help predict poor outcome and provide targets for intervention.

    The Role of Urocortins in Intracerebral Hemorrhage
    (MDPI, 2020-01) Choy, KerWoon; Tsai, Andy Po-Yi; Lin, Peter Bor-Chian; Wu, Meng-Yu; Lee, Chihyi; Alias, Aspalilah; Pang, Cheng-Yoong; Liew, Hock-Kean; Neurology, School of Medicine
    Intracerebral hemorrhage (ICH) causes an accumulation of blood in the brain parenchyma that disrupts the normal neurological function of the brain. Despite extensive clinical trials, no medical or surgical therapy has shown to be effective in managing ICH, resulting in a poor prognosis for the patients. Urocortin (UCN) is a 40-amino-acid endogenous neuropeptide that belongs to the corticotropin-releasing hormone (CRH) family. The effect of UCN is activated by binding to two G-protein coupled receptors, CRH-R1 and CRH-R2, which are expressed in brain neurons and glial cells in various brain regions. Current research has shown that UCN exerts neuroprotective effects in ICH models via anti-inflammatory effects, which generally reduced brain edema and reduced blood-brain barrier disruption. These effects gradually help in the improvement of the neurological outcome, and thus, UCN may be a potential therapeutic target in the treatment of ICH. This review summarizes the data published to date on the role of UCN in ICH and the possible protective mechanisms underlined.

    The National Institutes of Health Stroke Scale is comparable to the ICH score in predicting outcomes in spontaneous acute intracerebral hemorrhage
    (Frontiers Media, 2024-07-01) Kazaryan, Suzie A.; Shkirkova, Kristina; Saver, Jeffrey L.; Liebeskind, David S.; Starkman, Sidney; Bulic, Sebina; Poblete, Roy; Kim-Tenser, May; Guo, Shujing; Conwit, Robin; Villablanca, Pablo; Hamilton, Scott; Sanossian, Nerses; Neurology, School of Medicine
    Background: Validating the National Institutes of Health NIH Stroke Scale (NIHSS) as a tool to assess deficit severity and prognosis in patients with acute intracerebral hemorrhage would harmonize the assessment of intracerebral hemorrhage (ICH) and acute ischemic stroke (AIS) patients, enable clinical use of a readily implementable and non-imaging dependent prognostic tool, and improve monitoring of ICH care quality in administrative datasets. Methods: Among randomized trial ICH patients, the relation between NIHSS scores early after Emergency Department arrival and 3-month outcomes of dependency or death (modified Rankin Scale, mRS 3-6) and case fatality was examined. NIHSS predictive performance was compared to a current standard prognostic scale, the intracerebral hemorrhage score (ICH score). Results: Among the 384 patients, the mean age was 65 (±13), with 66% being male. The median NIHSS score was 16 (interquartile range (IQR) 9-25), the mean initial hematoma volume was 29 mL (±38), and the ICH score median was 1 (IQR 0-2). At 3 months, the mRS had a median of 4 (IQR 2-6), with dependency or death occurring in 70% and case fatality in 26%. The NIHSS and ICH scores were strongly correlated (r = 0.73), and each was strongly correlated with the 90-day mRS (NIHSS, r = 0.61; ICH score, r = 0.62). The NIHSS performed comparably to the ICH score in predicting both dependency or death (c = 0.80 vs. 0.80, p = 0.83) and case fatality (c = 0.78 vs. 0.80, p = 0.29). At threshold values, the NIHSS predicted dependency or death with 74.1% accuracy (NIHSS 17.5) and case fatality with 75.0% accuracy (NIHSS 18.5). Conclusion: The NIHSS forecasts 3-month functional and case fatality outcomes with accuracy comparable to the ICH Score. Widely documented in routine clinical care and administrative data, the NIHSS can serve as a valuable measure for clinical prognostication, therapy development, and case-mix risk adjustment in ICH patients.
