Abstract Background Fatigue is a common and disabling sequel after aneurysmal subarachnoid hemorrhage (aSAH). At present, prevalence estimates of post-aSAH fatigue in the chronic phase are scarce and vary greatly. Factors from the acute phase of aSAH have hitherto barely been associated with post-aSAH fatigue in the chronic phase. Methods Prospective study assessing prevalence of fatigue using the Fatigue Severity Scale (FSS) in patients who were living independently 1 to 7 years after aSAH. We compared demographic, medical, and radiological variables from the acute phase of aSAH between patients with and without fatigue (FSS ≥ 4 versus < 4) and searched for predictors of fatigue among these variables applying univariable and multivariable regression analyses. Results Of 726 patients treated for aSAH in the period between January 2012 and December 2017, 356 patients completed the assessment. The mean FSS score was 4.7 ± 1.7, and fatigue was present in 69.7%. The frequency of patients with fatigue did not decline significantly over time. Univariable analysis identified nicotine use, loss of consciousness at ictus (LOCi), rebleed prior to aneurysm repair, reduced consciousness to Glasgow Coma Scale (GCS) < 14, large amounts of subarachnoid blood, the presence of acute hydrocephalus, and severe vasospasm as factors that were significantly associated with fatigue. In multivariable analysis, nicotine use, reduced GCS, and severe vasospasm were independent predictors that all more than doubled the risk to develop post-aSAH fatigue. Conclusions Fatigue is a frequent sequel persisting several years after aSAH. Nicotine use, reduced consciousness at admission, and severe vasospasm are independent predictors of fatigue from the acute phase of aSAH. We propose inflammatory cytokines causing dopamine imbalance to be a common denominator for post-aSAH fatigue and the presently identified predictors.

OBJECTIVEDiverse treatment results are observed in patients with poor-grade aneurysmal subarachnoid hemorrhage (aSAH). Significant initial perfusion compromise is thought to predict a worse treatment outcome, but this has scant support in the literature. In this cohort study, the authors correlate the treatment outcomes with a novel poor-outcome imaging predictor representing impaired cerebral perfusion on initial CT angiography (CTA).METHODSThe authors reviewed the treatment results of 148 patients with poor-grade aSAH treated at a single tertiary referral center between 2007 and 2016. Patients with the “venous delay” phenomenon on initial CTA were identified. The outcome assessments used the modified Rankin Scale (mRS) at the 3rd month after aSAH. Factors that may have had an impact on outcome were retrospectively analyzed.RESULTSCompared with previously identified outcome predictors, the venous delay phenomenon on initial CTA was found to have the strongest correlation with posttreatment outcomes on both univariable (p < 0.0001) and multivariable analysis (OR 4.480, 95% CI 1.565–12.826; p = 0.0052). Older age and a higher Hunt and Hess grade at presentation were other factors that were associated with poor outcome, defined as an mRS score of 3 to 6.CONCLUSIONSThe venous delay phenomenon on initial CTA can serve as an imaging predictor for worse functional outcome and may aid in decision making when treating patients with poor-grade aSAH.

Introduction: Despite their high prevalence, prospective data on medical complications after aneurysmal subarachnoid hemorrhage (aSAH) and their contribution to functional outcome are sparse. We review rates of such events and correlate them to functional outcomes in three prospective datasets of patients with aSAH. Methods: Patients from two clinical trials (NEWTON-2, CONSCIOUS-1) and one clinical registry (Subarachnoid Hemorrhage Outcomes Project) were included. A good functional outcome was defined as a Glasgow Outcomes Scale (GOS) score of 4 or 5. Seventeen medical complications were assessed and their association with functional outcomes was determined with multivariable logistic regression. The variance in outcome explained by medical complications was calculated using difference in Nagelkerke’s R-squared. Results: Among the 1,430 patients, the most common complications were fever (564, 39%), anemia (410, 29%), and pneumonia (341, 24%). Patients who suffered any complication (OR: 0.45; 95% CI: 0.36 to 0.57; p<0.001) were less likely to have a good functional outcome in unadjusted analyses. In multivariable analysis, complications independently associated with lower rates of good functional outcome were anemia (OR: 0.60; 95% CI: 0.44 to 0.80; p<0.001), cardiac arrest (OR: 0.14; 95% CI: 0.05 to 0.37; p<0.001), pneumonia (OR: 0.48; 95% CI: 0.35 to 0.66; p<0.001), pulmonary edema (OR: 0.67; 95% CI: 0.45 to 0.99; p=0.047), and acute kidney injury (OR: 0.34; 95% CI: 0.12 to 0.98; p=0.047). A panel of eleven medical complications explained 8% of the variation in functional outcomes. Conclusions: Medical complications contribute to functional outcomes after aSAH, but their individual contributions to outcomes are relatively small. This should be noted when considering trials directed at preventing or treating any one complication and raises the question of studying comprehensive neurointensive care packages in the future.

Introduction: Cerebral vasospasm (CVS) and delayed cerebral ischemia (DCI) are frequently observed after aneurysmal subarachnoid hemorrhage (aSAH) and contribute to neurocognitive decline and worse outcomes. We hypothesize that aSAH initiates a cascade of neuroinflammatory events which contributes to the development of DCI. Methods: Patients who presented with aSAH requiring external ventricular drainage (EVD) for concomitant hydrocephalus were prospectively enrolled. Cerebrospinal fluid (CSF) samples were collected at different time-points relative to index aSAH injury: acute (days 0-1); pre-vasospasm (days 2-5); vasospasm peak (days 6-9) and post-vasospasm (days 10+). Presence and severity of CVS were assessed using CTA/CTP scans and clinical exam. VEGF and MMP9 (immune affectors) protein levels in the CSF were quantified using ELISA. Mobilization of the immune system was characterized by quantification of innate and adaptive immune cells in the CSF using flow cytometry. Production of inflammatory effector proteins was evaluated using intracellular cytokine staining. Results: Of 13 patients analyzed, 6 (46.2%) experienced CVS. Levels of VEGF and MMP9 were consistently higher in aSAH patients who developed CVS, with the highest difference occurring at the acute phase. Similarly, cellularity analysis revealed elevated counts of monocytes (CD11b + ) in the CSF during the acute phase, with progressive decline at later phases. Microglia (CD45 dim CD11b + ) cells were found to be significantly increased at the post-vasospasm phase. A higher percentage of IFN-γ production cytotoxic T helper cells were found at the acute phase, while the later time points revealed an elevated leveled of CD45RA - CD27 + cytotoxic T cells. Conclusion: Our preliminary data shows an active production of proteins with known immunological functions, mobilization of innate cells, production of inflammatory mediators by adaptive immune cells and altered differentiation status. Our overall goal is to determine if there are potential targets of immunomodulatory therapies which can be used to prevent or treat vasospasms and its related deleterious outcomes.

The Relationship

Background: Implementation of evidence-based performance metrics drive standardized care and improve patient outcomes. Limited performance metrics have been developed for implementation in the aneurysmal subarachnoid hemorrhage (aSAH) population. Timely aneurysm repair following an aSAH is associated with rebleeding prevention and mortality. The purpose of this study was to evaluate time to aneurysm repair as a candidate performance metric by testing a model that includes hospital and patient characteristics as predictors of time to aneurysm repair and mortality, with time to aneurysm repair as a potential influence on these relationships in aSAH. Methods: A retrospective, cross-sectional analysis of patient discharge data from 2014 in the state of Florida was conducted. Data were derived from The Agency for Healthcare Research and Quality, HealthCare Utilization Project, State Inpatient Dataset, and the American Hospital Association Annual Survey. Patients with a primary ICD-9 diagnosis of aSAH and principle procedure of clipping or coiling were included (n=387). The study outcome was in-hospital mortality. Independent variables were level of stroke center, age, race, sex, and type of aneurysm repair. Hierarchical logistic regression was used to estimate the probability of in-hospital death. Results: Patients who underwent endovascular repair of an aneurysm were more likely to be treated in <24 hours compared to those undergoing aneurysm clipping (OR = 0.54, CI = .35-.84, p =0.01). Patients treated at a comprehensive stroke center (CSC) had a 72% reduction in odds of death compared to those treated at primary stroke centers (OR =0.28, CI = 0.10-0.77, p =0.01), controlling for disease severity and comorbidity. Time to aneurysm repair was not significantly associated with mortality and did not influence the relationship between hospital and patient characteristics and mortality. Conclusions: Treatment at a certified CSC was the only significant predictor of surviving aSAH. Time to aneurysm repair did not influence the relationship between hospital and patient characteristics associated with mortality. Further research is needed to identify appropriate measures and to define what should be tracked for performance in the aSAH population.

OBJECT Intrasylvian hematoma (ISH) is a subtype of intracranial hematoma caused by aneurysmal rupture and often presents with a poor initial neurological grade; it is not well studied. The aim of this study was to elucidate outcomes of aneurysmal subarachnoid hemorrhage (SAH) with ISH. METHODS Data for 97 patients with poor-grade SAH (World Federation of Neurosurgical Societies Grade IV or V) were retrospectively analyzed from a single-center, prospective, observational cohort database. Ultra-early surgical clipping, removal of hematoma, external decompression for brain swelling, and prevention of vasospasm by cisternal irrigation with milrinone were combined as an aggressive treatment. Characteristics and clinical courses of SAH with ISH were identified. The authors also evaluated any correlations between poor admission-grade SAH and ISH with good functional outcome. RESULTS Patients with poor admission-grade SAH and with ISH were more likely to have initial cerebral edema (p < 0.001, Mann-Whitney U-test), which significantly resolved overtime (p < 0.001, Mann-Whitney U-test). These patients had a better chance of functional survival (modified Rankin Scale scores of 1–3; OR 5.75; 95% CI 1.36–24.3; p = 0.017) at 6 months after hospital discharge, after adjustment for potential confounders such as younger age and better initial neurological grade by multivariable analysis. CONCLUSIONS ISH predicted good functional recovery from poor-grade aneurysmal SAH.

Abstract Background While the smoking-related risk of experiencing an aneurysmal subarachnoid hemorrhage (aSAH) is well established, it remains unclear whether smoking has an unexpected “protective effect” in aSAH, or if smokers are more at risk for complications and poor outcomes. Methods Prospective, observational study investigating the course and outcome of aSAH in patients admitted during the years 2011 and 2012. Smoking status at admittance, demographic, medical, and radiological variables were registered along with management, complications, and outcome at 1 year in terms of mortality, modified Rankin score, and Glasgow outcome score extended. We compared current smokers with nonsmokers on group level and by paired analysis matched by aSAH severity, age, and severity of vasospasm. Results We included 237 patients, thereof 138 current smokers (58.2%). Seventy-four smoker/nonsmoker pairs were matched. Smokers presented more often in poor clinical grade, had less subarachnoid blood, and were younger than nonsmokers. Ruptured aneurysms were larger, and multiple aneurysms more common in smokers. Severe multi-vessel vasospasm was less frequent in smokers, whereas all other complications occurred at similar rates. Mortality at 30 days was lower in smokers and functional outcome was similar in smokers and nonsmokers. Poor clinical grade, age, cerebral infarction, and vertebrobasilar aneurysms were independent predictors of 1-year mortality and of poor functional outcome. Serious comorbidity was a predictor of 1-year mortality. Smoking did not predict mortality or poor functional outcome. Conclusions Notwithstanding clinically more severe aSAH, smokers developed less frequently severe vasospasm and had better outcome than expected. The risk for complications after aSAH is not increased in smokers.

OBJECTIVE This study investigated whether the increased incidence of aneurysmal subarachnoid hemorrhage (SAH) in winter is related to temperature or increased incidence of influenza. Such relationships may elucidate the pathogenesis of intracranial aneurysm rupture. METHODS A nationwide sample of 18,714 patients with SAH was linked with weekly temperature and influenza-like illness consultation data. Poisson regression analyses were used to calculate incidence density ratios (IDRs) with corresponding 95% CIs for the association of SAH incidence with temperature and influenza epidemics; IDRs were adjusted for study year (aIDR). In addition, SAH incidence data from 30 European population-based studies were linked with daily temperature data from the European Climate Assessment. RESULTS The aIDR for SAH during influenza epidemics was 1.061 (95% CI 1.022–1.101) in the univariable and 1.030 (95% CI 0.989–1.074) in the multivariable analysis. This association declined gradually during the weeks after epidemics. Per 1°C temperature drop, the aIDR was 1.005 (95% CI 1.003–1.008) in the univariable and 1.004 (95% CI 1.002–1.007) in the multivariable analysis. In the European population-based studies, the IDR was 1.143 (95% CI 1.129–1.157) per 1°C temperature drop. CONCLUSIONS The incidence of SAH is increased during cold temperatures and epidemic influenza. Future studies with individual patient data are needed to investigate causality between temperature or influenza and SAH.
