The Relationship

Background and Purpose: There have been conflicting reports regarding the association between peri-hematomal edema (PHE) in spontaneous intracerebral hemorrhage (ICH) and outcome. We hypothesized that PHE expansion rate from baseline to 24 hours predicts mortality and poor functional outcome after ICH. Methods: ICH, PHE and intraventricular hemorrhage volumes were measured for 139 subjects who presented with primary ICH and received head computed tomography scans at baseline and 24-hours post-ICH. Subjects were retrospectively identified from a prospective cohort study of ICH. Inclusion criteria were age over 18 years with primary spontaneous supratentorial ICH. Exclusion criteria were infratentorial hemorrhage, primary intraventricular hemorrhage, or any suspected cause of secondary ICH. Logistic regression was performed to evaluate the relationship between PHE expansion rate and 90-day mortality and functional outcome. Poor functional outcome was defined as a modified Rankin Scale (mRS) score > 2. Results: There was a strong association between PHE expansion rate and mortality (OR 1.42, p = 0.0025) and a trend in the correlation between PHE expansion rate and poor outcome (OR 1.50, p = 0.07). In a multivariable model accounting for hematoma volume and time from symptom onset to 24 hour scan, PHE expansion rate was a significant predictor of mortality (OR 1.07, p = 0.032). In a multivariable model accounting for hematoma volume, age, Glasgow Coma Scale score, presence of intraventricular hemorrhage and time from symptom onset to 24 hour scan, PHE expansion rate predicted poor functional outcome (OR 2.58, p = 0.05). Conclusions: PHE expansion rate predicts outcome in ICH and may represent a novel therapeutic target.

Perihemorrhagic Edema

ObjectiveTo determine the influence of intracerebral hemorrhage (ICH) location and volume and hematoma surface on perihemorrhagic edema evolution.MethodsPatients with ICH of the prospective Universitätsklinikum Erlangen Cohort of Patients With Spontaneous Intracerebral Hemorrhage (UKER-ICH) cohort study (NCT03183167) between 2010 and 2013 were analyzed. Hematoma and edema volume during hospital stay were volumetrically assessed, and time course of edema evolution and peak edema correlated to hematoma volume, location, and surface to verify the strength of the parameters on edema evolution.ResultsOverall, 300 patients with supratentorial ICH were analyzed. Peak edema showed a high correlation with hematoma surface (R2 = 0.864, p < 0.001) rather than with hematoma volumes, regardless of hematoma location. Smaller hematomas with a higher ratio of hematoma surface to volume showed exponentially higher relative edema (R2 = 0.755, p < 0.001). Multivariable logistic regression analysis revealed a cutoff ICH volume of 30 mL, beyond which an increase of total mass lesion volume (combined volume of hematoma and edema) was not associated with worse functional outcome. Specifically, peak edema was associated with worse functional outcome in ICH <30 mL (odds ratio [OR] 2.63, 95% confidence interval [CI] 1.68–4.12, p < 0.001), contrary to ICH ≥30 mL (OR 1.20, 95% CI 0.88–1.63, p = 0.247). There were no significant differences between patients with lobar and those with deep ICH after adjustment for hematoma volumes.ConclusionsPeak perihemorrhagic edema, although influencing mortality, is not associated with worse functional outcomes in ICH volumes >30 mL. Although hematoma volume correlates with peak edema extent, hematoma surface is the major parameter for edema evolution. The effect of edema on functional outcome is therefore more pronounced in smaller and irregularly shaped hematomas, and these patients may particularly benefit from edema-modifying therapies.

Intracerebral hemorrhage (ICH) can be divided into a primary and secondary phase. In the primary phase, hematoma volume is evaluated and therapies are focused on reducing hematoma expansion. In the secondary, neuroprotective phase, complex systemic inflammatory cascades, direct cellular toxicity, and blood-brain barrier disruption can result in worsening perihematomal edema that can adversely affect functional outcome. To date, all major randomized phase 3 trials for ICH have targeted primary phase hematoma volume and incorporated clot evacuation, intensive blood pressure control, and hemostasis. Reasons for this lack of clinical efficacy in the major ICH trials may be due to the lack of therapeutics involving mitigation of secondary injury and inflexible trial design that favors unilateral mechanisms in a complex pathophysiology. Potential pathophysiological targets for attenuating secondary injury are highlighted in this review and include therapies increasing calcium, antagonizing microglial activation, maintaining macrophage M1 versus M2 balance by decreasing M1 signaling, aquaporin inhibition, NKCCl inhibition, endothelin receptor inhibition, Sur1-TRPM4 inhibition, matrix metalloproteinase inhibition, and sphingosine-1-phosphate receptor modulation. Future clinical trials in ICH focusing on secondary phase injury and, potentially implementing adaptive trial design approaches with multifocal targets, may improve insight into these mechanisms and provide potential therapies that may improve survival and functional outcome.

Background Among prognostic imaging variables, the hematoma volume on admission computed tomography (CT) has long been considered the strongest predictor of outcome and mortality in intracerebral hemorrhage. Aims To examine whether different features of hematoma shape are associated with functional outcome in deep intracerebral hemorrhage. Methods We analyzed 790 patients from the ATACH-2 trial, and 14 shape features were quantified. We calculated Spearman’s Rho to assess the correlation between shape features and three-month modified Rankin scale (mRS) score, and the area under the receiver operating characteristic curve (AUC) to quantify the association between shape features and poor outcome defined as mRS>2 as well as mRS > 3. Results Among 14 shape features, the maximum intracerebral hemorrhage diameter in the coronal plane was the strongest predictor of functional outcome, with a maximum coronal diameter >∼3.5 cm indicating higher three-month mRS scores. The maximum coronal diameter versus hematoma volume yielded a Rho of 0.40 versus 0.35 ( p = 0.006), an AUC[mRS>2] of 0.71 versus 0.68 ( p = 0.004), and an AUC[mRS>3] of 0.71 versus 0.69 ( p = 0.029). In multiple regression analysis adjusted for known outcome predictors, the maximum coronal diameter was independently associated with three-month mRS (p < 0.001). Conclusions A coronal-plane maximum diameter measurement offers greater prognostic value in deep intracerebral hemorrhage than hematoma volume. This simple shape metric may expedite assessment of admission head CTs, offer a potential biomarker for hematoma size eligibility criteria in clinical trials, and may substitute volume in prognostic intracerebral hemorrhage scoring systems.

AbstractIntroduction.Several mechanisms in formation of perihemorrhagic edema are activated after contact of brain tissue-extravasated blood in intracerebral hemorrhage. Cysteinyl leukotrienes (cysLT) (C4, D4, E4) are included in this process as significant edema factors and they determine the neurological deficit and outcome. The study aim was a 5-day follow-up (admission/3 day/5 day) of urinary cysLT, hematoma volume, edema volume values and their correlation in patients after spontaneous, primary supratentorial intracerebral hemorrhage.Methods.An enzyme immunoassay was used for urinary cysLT measured in 62 patients and 80 healthy controls. Hematoma and edema volumes were visualized and measured by computed tomography and mathematically calculated with a special spheroid shape formula (V=AxBxC/2).Results.CysLT of hemorrhagic patients (1842.20±1413.2, 1181.54±906.2, 982.30±774.2pg/ml/mg creatinine) were significantly excreted (p<0.01). Brain edema (12.86±13.5, 22.38±21.1, 28.45±29.4cm3) was significantly increased (p<0.01). Hematoma volume values (13.05±14.5, 13.13±14.7, 12.99±14.7cm3) were not significant (p>0.05). A high correlation (multiple regression) between cysLT, hematoma and edema was found on the 3rdday (R=0.6) and a moderate correlation at admission (R=0.3) and on the 5thday (R=0.3).Conclusion.In our 5-day follow-up study a significant cysLT brain synthesis and significant brain edema progression versus constant hematoma volume values in hemorrhagic patients was found. A high correlation between cysLT, hematoma and edema volume was found on the 3rdday, a moderate correlation on admission and on the 5thday, which means that high cysLT and hematoma values were associated with high/moderate edema values.

Background and Objective: Vitamin D deficiency is internationally recognized among the potentially modifiable risk factors for ischemic cardio-cerebrovascular diseases. However, the association between vitamin D deficiency and stroke morbidity or mortality remains insufficiently known. Our aim is to investigate their relevance to 25-hydroxyvitamin D [25(OH) D] levels and clinical severity and outcome after 3 months in first-ever ischemic stroke. Methods: Retrospective analysis of 356 consecutive patients in first-ever ischemic stroke between 2013 and 2015. Serum 25(OH) D levels were measured at baseline. Stroke severity was assessed at admission using the National Institutes of Health Stroke Scale (NIHSS) score. Functional outcome after 3 months of onset was evaluated using the modified Rankin scale (mRS). Results: Among the 356 enrolled patients, HbA1c was higher in insufficiency/deficiency group than that in the sufficiency group (6.3 ± 1.7 vs. 5.9 ± 1.1, p =0.015). The hospital stay was longer in insufficiency/deficiency group than that in the sufficiency group (11 (8-17) vs. 9.5 (7-13), p = 0.035). There was a significant inversed trend between serum 25(OH) D levels and hospital stay (OR 0.960, P = 0.031), using logistic regression. Conclusions: 25(OH)D levels are associated with glucose homeostasis, 25(OH) D contributes to increase the length of hospital stay. Low serum 25-OHD level is an independent predictor for hospital stay in first-ever ischemic stroke. Vitamin D deficiency did not predict functional outcome in the span of 3 months.

Abstract Background Neuroinflammation is important in the pathophysiology of spontaneous intracerebral hemorrhage (ICH) and peripheral inflammatory cells play a role in the clinical evolution and outcome. Methodology Blood samples from ICH patients (n = 20) were collected at admission for 5 consecutive days for peripheral blood mononuclear cells (PBMCs). Frozen PBMCs were used for real-time PCR using Taqman probes (NFKB1, SOD1, PPARG, IL10, NFE2L2, and REL) and normalized to GAPDH. Data on hospital length of stay and modified Rankin score (MRS) were collected with 90-day MRS ≤ 3 as favorable outcome. Statistical analysis of clinical characteristics to temporal gene expression from early to delayed timepoints was compared for MRS groups (favorable vs unfavorable) and hematoma volume. Principle findings and results IL10, SOD1, and REL expression were significantly higher at delayed timepoints in PBMCs of ICH patients with favorable outcome. PPARG and REL increased between timepoints in patients with favorable outcome. NFKB1 expression was not sustained, but significantly decreased from higher levels at early onset in patients with unfavorable outcome. IL10 expression showed a negative correlation in patients with high hematoma volume (>30 mL). Conclusions and significance Anti-inflammatory, pro-survival regulators were highly expressed at delayed time points in ICH patients with a favorable outcome, and IL10 expression showed a negative correlation to high hematoma volume.

Background: Neurological deterioration (ND) has a major influence on the prognosis of intracerebral hemorrhage (ICH); however, factors associated with ND occurring after 24 h of ICH onset are unknown. Methods: We performed exploratory analyses of data from the Antihypertensive Treatment of Acute Cerebral Hemorrhage 2 trial, which compared intensive and standard blood pressure lowering treatment in ICH. NDs were captured on the adverse event case report form. Logistic regression analysis was performed to examine the independent predictors of late ND. Results: Among 1,000 participants with acute ICH, 82 patients (8.2%) developed early ND (≤24 h), and 64 (6.4%) had late ND. Baseline hematoma volume (adjusted OR [aOR] per 1-cm3 increase 1.04, 95% CI 1.02–1.06, p < 0.0001), hematoma volume increase in 24 h (aOR 2.24, 95% CI 1.23–4.07, p = 0.008), and the presence of intraventricular hemorrhage (IVH; aOR 2.38, 95% CI 1.32–4.29, p = 0.004) were independent predictors of late ND (vs. no late ND). Late ND was a significant risk factor for poor 90-day outcome (OR 3.46, 95% CI 1.82–6.56). No statistically significant difference in the incidence of late ND was noted between the 2 treatment groups. Conclusions: Initial hematoma volume, early hematoma volume expansion, and IVH are independent predictors of late ND after ICH. Intensive reduction in the systolic blood pressure level does not prevent the development of late ND.
