Abstract
Introduction Intracranial aneurysms occur in 3%-5% of the general population. While the precise biological mechanisms underlying the formation, growth, and sudden rupture of intracranial aneurysms remain partially unknown, recent research has shed light on the potential role of inflammation in aneurysm development and rupture. In addition, there are ongoing investigations exploring the feasibility of employing new drug therapies for controlling the risk factors associated with aneurysms. CD68, a glycosylated glycoprotein and the human homolog of macrosialin, is prominently expressed in monocyte/macrophages within inflamed tissues and has shown potential application in oncology. An observational study was conducted with the aim of comparing the histological characteristics of aneurysm walls with preoperative MRI scans, specifically focusing on CD68 activity. Method An observational pilot study was conducted to investigate the histological characteristics of the aneurysm wall that could be potentially associated with aneurysm growth and rupture. A total of 22 patients diagnosed with ruptured and unruptured intracranial aneurysms who had undergone conventional clipping between January 2017 and December 2022 were included in the study. Results A histopathological analysis of the aneurysm wall was performed in all patients, particularly focusing on the presence of CD68. A preoperative MRI with gadolinium was conducted in 10 patients with unruptured aneurysms and six patients with ruptured aneurysms. An emergency clipping was performed in the remaining six patients. The results showed that CD68 positivity and wall enhancement were significantly associated with intracranial aneurysm wall degeneration, growth, and rupture. Conclusion The histological and radiological inflammatory findings observed in the wall of cerebral aneurysms, as well as the CD68 positivity, are significantly associated with the risk of intracranial aneurysm growth and rupture. This study highlights the crucial importance of considering clinical and medical data when making treatment decisions for intracranial aneurysms. Furthermore, it emphasizes the relevance of evaluating wall enhancement in MRI scans as part of the diagnostic and prognostic process.

Continuous lumbar drainage after aneurysmal subarachnoid hemorrhage decreased malondialdehyde in cerebrospinal fluid and improved outcome. J Formos Med Assoc 2023; 122:164-171. [PMID: 36117035 DOI: 10.1016/j.jfma.2022.09.001] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2022] [Revised: 07/31/2022] [Accepted: 09/01/2022] [Indexed: 02/03/2023] Open
Abstract
PURPOSE The use of a continuous lumbar drain (LD) for the treatment of aneurysmal subarachnoid hemorrhage (aSAH), and malondialdehyde (MDA), a marker of oxidative stress, is correlated with clinical outcome. This study aimed to investigate the relationship between LD placement and MDA level after aSAH. METHODS Patients with modified Fisher's grade III and IV aSAH who underwent early aneurysm obliteration were enrolled. Cerebrospinal fluid (CSF) was obtained on day 7 after aSAH in non-LD group. In LD group, the LD was inserted on day 3 after aSAH for continuous CSF drainage. The levels of intrathecal hemoglobin, total bilirubin, ferritin, and MDA were measured. RESULTS There were 41 patients in non-LD group (age: 58.7 ± 13.7 years; female: 61.0%) and 48 patients in LD group (age: 58.3 ± 10.4 years; female: 79.2%). There were more favorable outcomes (Glasgow Outcome Scale ≥4) at 3 months after aSAH in LD group (p = 0.0042). The intrathecal hemoglobin, total bilirubin, ferritin, and MDA levels at day 7 after aSAH were all significantly lower in LD group. An older age (>60 years) (p = 0.0293), higher MDA level in the CSF (p = 0.0208), and delayed ischemic neurological deficit (p = 0.0451) were independent factors associated with unfavorable outcomes. LD placement was associated with a decreased intrathecal MDA level on day 7 after aSAH (p < 0.001). CONCLUSION The intrathecal MDA level at day 7 after aSAH can be an effective outcome indicator in modified Fisher's grade III/IV aSAH. Continuous CSF drainage via a LD can decrease the intrathecal MDA level and improve the functional outcome.

Abstract
OBJECTIVE The harmful effects of hyperoxemia have been reported in critically ill patients with various disorders, including those with brain injuries. However, the effect of hyperoxemia on aneurysmal subarachnoid hemorrhage (aSAH) patients is unclear. In this study the authors aimed to determine whether hyperoxemia during the hyperacute or acute phase in patients with aSAH is associated with delayed cerebral ischemia (DCI) and poor neurological outcome. METHODS In this single-center retrospective study, data from patients with aSAH treated between January 2011 and June 2017 were reviewed. The patients were classified into groups according to whether they experienced DCI (DCI group and non-DCI group) and whether they had a poor outcome at discharge (poor outcome group and favorable outcome group). The background characteristics and time-weighted average (TWA) PaO2 during the first 24 hours after arrival at the treatment facility (TWA24h-PaO2) and between the first 24 hours after arrival and day 6 (TWA6d-PaO2), the hyperacute and acute phases, respectively, were compared between the groups. Factors related to DCI and poor outcome were evaluated with logistic regression analyses. RESULTS Of 197 patients with aSAH, 42 patients experienced DCI and 82 patients had a poor outcome at discharge. TWA24h-PaO2 was significantly higher in the DCI group than in the non-DCI group (186 [141-213] vs 161 [138-192] mm Hg, p = 0.029) and in the poor outcome group than in the favorable outcome group (176 [154-205] vs 156 [136-188] mm Hg, p = 0.004). TWA6d-PaO2 did not differ significantly between the groups. Logistic regression analyses revealed that higher TWA24h-PaO2 was an independent risk factor for DCI (OR 1.09, 95% CI 1.01-1.17, p = 0.037) and poor outcome (OR 1.17, 95% CI 1.06-1.29, p = 0.002). CONCLUSIONS Hyperoxemia during the first 24 hours was associated with DCI and a poor outcome in patients with aSAH. Excessive oxygen therapy might have an adverse effect in the hyperacute phase of aSAH.

Abstract
Oxidative stress is regarded to play a crucial role in the pathophysiology of pulmonary arterial hypertension (PAH) and inoperable chronic thromboembolic pulmonary hypertension (CTEPH). This study evaluated the prognostic value of serum oxidative stress markers (malondialdehyde (MDA), total antioxidant capacity (TAC), catalase activity (CAT), and superoxide activity (SOD)) in patients with PAH and CTEPH (n = 45). During 13 months of follow-up (median 9 months), clinical deterioration occurred in 14 patients (including 2 deaths). On the Cox regression analysis, MDA, TAC, and CAT were associated with clinical deterioration (p = 0.0068, HR = 1.42, 95% CI: 1.10-1.82; p = 0.0038, HR = 0.033, 95% CI: 0.0032-0.33; and p = 0.046, HR = 0.20, 95% CI: 0.04-0.98, respectively). There was no significant difference in SOD (p = 0.53, HR = 0.97, 95% CI: 0.87-1.08). The cut-off value derived from ROC curve analysis was 3.79 μM (p = 0.0048, AUC = 0.76, 95% CI: 0.62-0.91) for MDA, 0.49 mM (p = 0.027, AUC = 0.71, 95% CI: 0.18-0.47) for TAC, and 1.34 U/L (p = 0.029, AUC = 0.71, 95% CI: 0.55-0.86) for CAT. MDA in the group with deterioration was higher (p = 0.0041), while TAC as well as CAT were lower (p = 0.027 and p = 0.028, respectively) when compared to stable patients. Survival without clinical deterioration was significantly longer in patients with lower MDA (p = 0.037, HR = 0.37, 95% CI: 0.12-1.14, log-rank), higher TAC (p = 0.0018, HR = 0.19, 95% CI: 0.06-0.60, log-rank), and higher CAT (p = 0.044, HR = 0.31 95% CI: 0.11-0.88, log-rank). Markers of oxidative stress such as MDA, TAC, and CAT were associated with adverse clinical outcomes in patients with PAH and inoperable or residual CTEPH.

Role of Damage Associated Molecular Pattern Molecules (DAMPs) in Aneurysmal Subarachnoid Hemorrhage (aSAH). Int J Mol Sci 2018; 19:ijms19072035. [PMID: 30011792 PMCID: PMC6073937 DOI: 10.3390/ijms19072035] [Citation(s) in RCA: 60] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Revised: 07/01/2018] [Accepted: 07/09/2018] [Indexed: 12/27/2022] Open
Abstract
Aneurysmal subarachnoid hemorrhage (aSAH) represents only a small portion of all strokes, but accounts for almost half of the deaths caused by stroke worldwide. Neurosurgical clipping and endovascular coiling can successfully obliterate the bleeding aneurysms, but ensuing complications such as cerebral vasospasm, acute and chronic hydrocephalus, seizures, cortical spreading depression, delayed ischemic neurological deficits, and delayed cerebral ischemia lead to poor clinical outcomes. The mechanisms leading to these complications are complex and poorly understood. Early brain injury resulting from transient global ischemia can release molecules that may be critical to initiate and sustain inflammatory response. Hence, the events during early brain injury can influence the occurrence of delayed brain injury. Since the damage associated molecular pattern molecules (DAMPs) might be the initiators of inflammation in the pathophysiology of aSAH, so the aim of this review is to highlight their role in the context of aSAH from diagnostic, prognostic, therapeutic, and drug therapy monitoring perspectives. DAMPs represent a diverse and a heterogenous group of molecules derived from different compartments of cells upon injury. Here, we have reviewed the most important DAMPs molecules including high mobility group box-1 (HMGB1), S100B, hemoglobin and its derivatives, extracellular matrix components, IL-1α, IL-33, and mitochondrial DNA in the context of aSAH and their role in post-aSAH complications and clinical outcome after aSAH.

Abstract
Free radical toxicity is considered as a key mechanism in the neuronal damage occurring after aneurysmal subarachnoid haemorrhage (SAH). We measured markers of DNA and RNA damage from oxidation (8-oxodG and 8-oxoGuo, respectively) in cerebrospinal fluid from 45 patients with SAH on day 1-14 after ictus and 45 age-matched healthy control subjects. At baseline, both markers were significantly increased in patients compared to controls (p values < .001), and exhibited a progressive further increase (to >20-fold above control levels) from day 5-14. None of the markers predicted the occurrence of vasospasms or mortality, although there was a trend that the 8-oxoGuo marker was more strongly associated with mortality than the 8-oxodG marker. We conclude that SAH leads to a massive increase in damage to nucleic acids from oxidative stress, which is likely to play a role in neuronal dysfunction and death. As only patients in need of a ventriculostomy catheter were included in the study, the findings cannot necessarily be extrapolated to all patients with SAH.

Abstract
OBJECTIVE The presence, extent, and distribution of intraventricular hemorrhage (IVH) have been associated with negative outcomes in aneurysmal subarachnoid hemorrhage (SAH). Several qualitative scores (Fisher grade, LeRoux score, and Graeb score) have been established for evaluating SAH and IVH. However, no study has assessed the radiodensity within the ventricular system in aneurysmal SAH patients with IVH. Prior studies have suggested that hemorrhage with a higher radiodensity, as measured by CT Hounsfield units, can cause more irritation to brain parenchyma. Therefore, the authors set out to investigate the relationship between the overall radiodensity of the ventricular system in aneurysmal SAH patients with IVH and their clinical outcome scores. METHODS The authors reviewed the records of 101 patients who were admitted to their institution with aneurysmal SAH and IVH between January 2011 and July 2015. The following data were collected: age, sex, Glasgow Coma Scale (GCS) score, Hunt and Hess grade, extent of SAH (none, thin, or thick/localized), aneurysm location, and Glasgow Outcome Scale (GOS) score. To evaluate the ventricular radiodensity, the initial head CT scan was loaded into OsiriX MD. The ventricular system was manually selected as the region of interest (ROI) through all pertinent axial slices. After this, an averaged ventricular radiodensity was calculated from the ROI by the software. GOS scores were dichotomized as 1-3 and 4-5 subgroups for analysis. RESULTS On univariate analysis, younger age, higher GCS score, lower Hunt and Hess grade, and lower ventricular radiodensity significantly correlated with better GOS scores (all p < 0.05). Subsequent multivariate analysis yielded age (OR 0.936, 95% CI 0.895-0.979), GCS score (OR 3.422, 95% CI 1.9-6.164), and ventricular density (OR 0.937, 95% CI 0.878-0.999) as significant independent predictors (p < 0.05). A receiver operating characteristic curve yielded 12.7 HU (area under the curve 0.625, p = 0.032, sensitivity = 0.591, specificity = 0.596) as threshold between GOS scores of 1-3 and 4-5. CONCLUSIONS This study suggests that the ventricular radiodensity in aneurysmal SAH patients with IVH, along with GCS score and age, may serve as a predictor of clinical outcome.

Abstract
BACKGROUND 8-iso-Prostaglandin F2α (8-iso-PGF2α) is a potential biomarker of oxidative stress. This study clarified whether plasma 8-iso-PGF2α concentrations were affected and its underlying relevance to prognosis in aneurysmal subarachnoid hemorrhage (aSAH). METHODS In this prospective, observational study, a total of 170 controls and 170 aSAH patients were enrolled. Plasma 8-iso-PGF2α concentrations were detected using an ELISA. Severity was assessed by World Federation of Neurological Surgeons (WFNS) scale and modified Fisher grading scale. Clinical outcomes included 6-month mortality and poor outcome referred to as Glasgow outcome scale score of 1-3. RESULTS As compared to controls, admission plasma 8-iso-PGF2α concentrations were significantly enhanced. Increased concentrations of plasma 8-iso-PGF2α correlated with WFNS scores and modified Fisher scores. 8-iso-PGF2α in plasma was an independent predictor for clinical outcomes. Under ROC curve, the predictive values of 8-iso-PGF2α concentrations resembled those of WFNS scores and modified Fisher scores for clinical outcomes. CONCLUSIONS An elevation in plasma 8-iso-PGF2α concentrations is associated with the severity and poor outcome after aSAH, substantializing 8-iso-PGF2α as a potential prognostic biomarker of aSAH.

Abstract
AbstractSubarachnoid hemorrhage (SAH) is a devastating disease with high mortality and mobility, the novel therapeutic strategies of which are essentially required. The calcium binding protein S100B has emerged as a brain injury biomarker that is implicated in pathogenic process of SAH. S100B is mainly expressed in astrocytes of the central nervous system and functions through initiating intracellular signaling or via interacting with cell surface receptor, such as the receptor of advanced glycation end products. The biological roles of S100B in neurons have been closely associated with its concentrations, resulting in either neuroprotection or neurotoxicity. The levels of S100B in the blood have been suggested as a biomarker to predict the progress or the prognosis of SAH. The role of S100B in the development of cerebral vasospasm and brain damage may result from the induction of oxidative stress and neuroinflammation after SAH. To get further insight into mechanisms underlying the role of S100B in SAH based on this review might help us to find novel therapeutic targets for SAH.

Abstract
S100 calcium binding protein B (S100B), a well-studied marker for neurologic injury, has been suggested as a candidate for predicting outcome after subarachnoid hemorrhage. We performed a pooled analysis summarizing the associations between S100B protein in serum and cerebrospinal fluid (CSF) with radiographic vasospasm, delayed ischemic neurologic deficit (DIND), delayed cerebral infarction, and Glasgow Outcome Scale (GOS) outcome. A literature search using PubMed, the Cochrane Library, and the EMBASE databases was performed to identify relevant studies published up to May 2015. The weighted Stouffer's Z method was used to perform a pooled analysis of outcome measures with greater than three studies. A total of 13 studies were included in this review. Higher serum S100B level was found to be associated with cerebral infarction as diagnosed by CT (padj = 3.1 x 10(-4)) and worse GOS outcome (padj = 5.5 x 10(-11)). There was no association found between serum and CSF S100B with radiographic vasospasm or DIND. S100B is a potential prognostic marker for aSAH outcome.

Abstract
BACKGROUND Several studies reported prognostic value of biomarker in intracerebral hemorrhagic (ICH) but they are either preliminary observation or inadequately powered to analyse independent contribution of biomarkers over and above clinical and neuroimaging data. OBJECTIVE To examine whether the biomarker can significantly add to the predictive accuracy of prognosis of ICH. METHOD/DESIGN In a multi-centric prospective cohort study, 1020 patients with ICH within 72 hours of onset are being recruited. After obtaining written informed consent from patients/proxy, venous blood sample (10 ml) is being collected and analysed for C-reactive protein (CRP) level, S100B, Glial fibrillary acidic protein (GFAP), Troponin, change in leukocyte count and Copeptin levels. The patients are telephonically followed using stroke scales (Barthel Index and modified Rankin Scale) at 3, 6, 12 months and 2 years after the recruitment. DISCUSSION This protocol will aim at predicting the short term or long term prognosis with the use of clinical, neuroimaging and biomarkers in order to help clinician to stratify patients for early referral or intervention.

Abstract
Background The failures of recent studies intended to prevent cerebral vasospasm have moved the focus of research into delayed cerebral ischemia away from cerebral artery constriction towards other mechanisms. Recent accumulating evidence has suggested that early brain injury is also involved in the development of delayed cerebral ischemia, and that hydrogen can prevent early brain injury. Therefore, we have established a combination therapy of intravenous hydrogen infusion and intra-cisternal magnesium sulfate infusion for the treatment of both early brain injury and cerebral vasospasm. The present randomized controlled clinical trial is designed to investigate the effects of this novel therapeutic strategy on the occurrence of cerebral vasospasm, delayed cerebral ischemia, and clinical outcomes after high-grade subarachnoid hemorrhage. Methods This study is a randomized, double-blind, placebo-controlled design to be conducted in two hospitals. A total of 450 patients with high-grade subarachnoid hemorrhage will be randomized to one of three arms: (i) Mg + H2 group, (ii) Mg group, and (iii) control group. Patients who are assigned to the Mg + H2 group will receive intra-cisternal magnesium sulfate infusion (2.5 mmol/L) at 20 mL/h for 14 days and intravenous hydrogen-rich fluid infusion (200 mL) twice a day for 14 days. Patients who are assigned to the Mg group will receive intra-cisternal magnesium sulfate infusion (2.5 mmol/L) at 20 mL/h for 14 days and intravenous normal glucose-electrolyte solution (200 mL) without added hydrogen twice a day for 14 days. Patients who are assigned to the control group will receive intra-cisternal Ringer solution without magnesium sulfate at 20 mL/h for 14 days and intravenous normal glucose-electrolyte solution (200 mL) without added hydrogen twice a day for 14 days. Primary outcome measures will be occurrence of delayed cerebral ischemia and cerebral vasospasm. Secondary outcome measures will be modified Rankin scale score at 3, 6, and 12 months and biochemical markers. Discussion The present protocol for a randomized, placebo-controlled study of intravenous hydrogen therapy with intra-cisternal magnesium infusion is expected to establish the efficacy and safety of this therapeutic strategy.

Abstract
CONTEXT Subarachnoid hemorrhage (SAH) has a high fatality rate and many suffer from delayed neurological deficits. Biomarkers may aid in the identification of high-risk patients, guide treatment/management and improve outcome. OBJECTIVE The aim of this review was to summarize biomarkers of SAH associated with outcome. METHODS An electronic database query was completed, including an additional review of reference lists to include all potential human studies. RESULTS A total of 298 articles were identified; 112 were reviewed; 55 studies were included. CONCLUSION This review details biomarkers of SAH that correlate with outcome. It provides the basis for research investigating their possible translation into the management of SAH patients.

Abstract
Varicella-zoster virus (VZV) is one of our most common viruses causing central nervous system (CNS) infection with sometimes severe neurological complications. Glial fibrillary acidic protein (GFAp), light subunit of neurofilament protein (NFL) and S-100β protein are cerebrospinal fluid (CSF) biomarkers that have been used to estimate the severity of brain damage and outcome in various CNS diseases. So far, these biomarkers have not been utilised to investigate glial pathology and neuronal damage in patients with VZV CNS infections. In this prospective study, we measured CSF GFAp, NFL and S-100β as markers of brain damage in 24 patients with acute neurological manifestations and VZV DNA detected in CSF by PCR and compared with a control group (n = 14). Concentrations of CSF NFL and GFAp were increased in patients with VZV CNS infection compared with controls (p = 0.002 and p = 0.03) while levels of S-100β were reduced. In patients with VZV encephalitis the elevations of CSF NFL and GFAp were more pronounced compared with patients with other VZV CNS syndromes. No correlations between the levels of biomarkers and viral load, neurological sequels or clinical outcome were found in this limited number of patients. These results indicate that VZV induces neuronal damage and astrogliosis with more severe brain damage in patients with VZV encephalitis than in patients with other neurological complications caused by this virus.

Abstract
Background and Purpose—
A number of scores were developed to predict outcomes after clipping for subarachnoid hemorrhages, yet there is no score for patients undergoing endovascular treatment. Our goal was to develop, compare, and validate a predictive score for 1-year outcomes in patients with coiled subarachnoid hemorrhage.
Methods—
We studied 526 patients for 1 year after intensive care unit discharge. We developed an admission bioclinical score (ABC score), which integrated biomarkers such as troponin I and S100β, with the Glasgow Coma Scale. Using the receiver operating characteristic curve (95% CI), the ABC score was compared with the Glasgow Coma Scale, World Federation of Neurosurgical Societies score, and Fisher score in the derivation cohort and further validated in an independent cohort.
Results—
In the derivation cohort (from 2003–2007, n=368), multivariate logistic regression analysis showed that only Glasgow Coma Scale (
P
<0.001), high S100β (
P
<0.001), and high troponin (
P
<0.02) were independently associated with 1-year mortality. Troponin, S100β, and Glasgow Coma Scale were thus integrated to derive the ABC score. In the derivation cohort, the ABC score reached an receiver operating characteristic curve of 0.82 (0.77–0.88,
P
<0.001) and was significantly greater than the receiver operating characteristic curves of the Glasgow Coma Scale, World Federation of Neurosurgical Societies, and Fisher scores for predicting 1-year mortality. In the validation cohort (from 2008–2009, n=158), the ABC score's receiver operating characteristic curve of 0.76 (0.67–0.86,
P
<0.001) remained superior to the 3 other scores for predicting 1-year mortality.
Conclusions—
The ABC score improves 1-year outcome prediction at admission for patients with coiled subarachnoid hemorrhage. Our study provides large cohort-based evidence supporting integration of individual biomarkers and clinical characteristics to predict outcomes.

Abstract
An increase in oxidative stress and overproduction of oxidizing reactive species plays an important role in the pathophysiology of several conditions encountered in the neurocritical care setting including: ischemic and hemorrhagic strokes, traumatic brain injury, acute respiratory distress syndrome, sepsis, and organ failure. The presence of oxidative stress in these conditions is supported by a large body of pre-clinical and clinical studies, and provides a rationale to support a potential therapeutic role for antioxidants. The purpose of this article is to briefly review the basic mechanisms and molecular biology of oxidative stress, summarize its role in critically ill neurological patients, and review available data regarding the potential role of antioxidant strategies in neurocritical care and future directions.

Abstract
Subarachnoid hemorrhage (SAH) comprises only about 7% of all strokes worldwide but is associated with severe mortality and morbidity. SAH is associated with a number of secondary pathologies, such as: transient cerebral vasospasm, delayed ischemic neuronal deficit (DIND), cortical spreading depression, microcirculatory modifications, microthrombosis and ischemic complications. Available data demonstrate that there are complex interactions among these secondary complications, and NO plays an important role among the interactions. NO has been implicated to be a crucial molecule in eliminating vasospasm, facilitating neuroprotection, anti-microthrombosis, cerebral ischemic tolerance and promoting endothelial cell function. Therefore, therapeutic agent targeting a key component in the pathopyhysiology of SAH such as NO and its related enzymes would be favorable for future development of SAH drugs. Alternatively, because of the complex nature of the secondary complications after SAH, agents with multiple efficacies on these complications, or the combination of several agents such as NO donors, oxide radical scavengers and neuroprotectants might be more desirable.
