Intracerebral hemorrhage (ICH), a subtype of stroke, brings high morbidity and mortality to human beings. Multiple studies indicate that neuroinflammation, excitotoxicity, oxidative stress, cytotoxicity resulted from the degradation products of blood clot play vital roles in ICH-induced secondary brain injury, which contributes to deterioration of neurological outcome. Prostaglandin E2 (PGE2), a type of prostanoids commonly up-regulated in these progresses, is known to modulate numerous cellular and molecular processes and involve in various diseases, including ICH, cerebral ischemic, Alzheimer's disease (AD) and amyotrophic lateral sclerosis (ALS) etc...

Krista Lim-Hing, Fred Rincon
Intracerebral hemorrhages (ICH) represent about 10-15% of all strokes per year in the United States alone. Key variables influencing the long-term outcome after ICH are hematoma size and growth. Although death may occur at the time of the hemorrhage, delayed neurologic deterioration frequently occurs with hematoma growth and neuronal injury of the surrounding tissue. Perihematoma edema has also been implicated as a contributing factor for delayed neurologic deterioration after ICH. Cerebral edema results from both blood-brain barrier disruption and local generation of osmotically active substances...

Spreading depolarizations (SDs) are highly active metabolic events, commonly occur in patients with intracerebral hemorrhage (ICH) and may be triggered by fever. We investigated the dynamics of brain-temperature (Tbrain) and core-temperature (Tcore) relative to the occurrence of SDs. Twenty consecutive comatose ICH patients with multimodal electrocorticograpy (ECoG) and Tbrain monitoring of the perihematomal area were prospectively enrolled. Clusters of SDs were defined as ≥2 SDs/h. Generalized estimating equations were used for statistical calculations...

OBJECTIVES: The timing and modality of intervention in the treatment of poor-grade aneurysmal subarachnoid haemorrhage (aSAH) has not been defined. The purpose of the study is to analyse whether early treatment and type of intervention influence the clinical outcomes of poor-grade aSAH patients. MATERIAL AND METHODS: Patients with poor-grade aSAH were retrieved. Demographics, Fisher grade, radiological characteristics and clinical outcomes were recorded. Outcomes were compared using the modified Rankin Scale (mRS), for groups treated early within 24 hours of aSAH or later and by clipping or endovascular therapy...

BACKGROUND: Autoantibodies against Factor VIII (FVIII) define the rare but life-threatening bleeding disorder acquired hemophilia A (AHA). Correction of FVIII deficiency and eradication of the factor inhibitor are the ultimate therapeutic goals in this disorder. Bypassing agents such as recombinant factor VIIa (rFVIIa) or FVIII inhibitor bypassing agent are often used to control coagulopathy before the inhibitor is eradicated. Bypassing agents carry a risk of thrombosis, however. CASE REPORT: We report a patient with newly diagnosed AHA and thalamic bleed who additionally had active atrial fibrillation and developed a segmental pulmonary embolism, limiting tolerable rFVIIa dosage...

OBJECTIVES: The use of antiplatelet therapy after intracerebral hemorrhage remains controversial, while the use of dual antiplatelet therapy (DAPT) is required after cardiac stenting. In this study, we examine the risk of bleeding and ischemic events for PCI patients with a history of hypertensive hemorrhage on DAPT. METHODS: A total of 128 cases and 153 controls were selected from Chinese patients with cardiac stenting on dual anti-platelet therapy for a single-center retrospective case-control study...

OBJECTIVES: Clinical outcome after intracerebral hemorrhage (ICH) remains poor. Definitive phase-3 trials in ICH have failed to demonstrate improved outcomes with intensive systolic blood pressure (SBP) lowering. We sought to determine whether other BP parameters-diastolic BP (DBP), pulse pressure (PP), and mean arterial pressure (MAP)-showed an association with clinical outcome in ICH. METHODS: We retrospectively analyzed a prospective cohort of 672 patients with spontaneous ICH and documented demographic characteristics, stroke severity, and neuroimaging parameters...

Immunity plays key roles in pathophysiology of intracerebral hemorrhage (ICH). The aim of the study was to determine whether the peripheral leukocyte count and neutrophil-to-lymphocyte ratio (NLR) predicted neurological deterioration (ND) after ICH. We identified consecutive patients with ICH who had blood sampling performed within 24 hours from symptom's onset. Total white blood cells (WBC), absolute neutrophil count (ANC) and absolute lymphocyte count (ALC) were retrieved, and the NLR computed as the ratio of the ANC to ALC values...

BACKGROUND: Decompressive craniectomy is performed to relieve intracranial pressure as an emergency procedure. There is no large study to systematically evaluate the benefit of decompressive craniectomy versus best medical therapy. This study evaluates the survival and long-term functional outcomes of decompressive craniectomy for spontaneous intracranial hemorrhage. METHODS: A total of 54 eligible patients with spontaneous supratentorial hemorrhage (median age 55, IQR 47-64) who underwent decompressive craniectomy were retrospectively matched to 72 patients managed with best medical treatment (median age 58, IQR 32-74)...

OBJECTIVE: To compare outcomes after intracerebral hemorrhage (ICH) from cerebral arteriovenous malformation (AVM) rupture and other causes of ICH. METHODS: We performed a retrospective population-based study using data from the Nationwide Inpatient Sample. We used standard diagnosis codes to identify ICH cases from 2002 to 2011. Our predictor variable was cerebral AVM. Our primary outcomes were inpatient mortality and home discharge. We used logistic regression to compare outcomes between patients with ICH with and without AVM while adjusting for demographics, comorbidities, and hospital characteristics...

BACKGROUND: Strokes secondary to acute internal carotid artery (ICA) occlusion are associated with an extremely poor prognosis. The best treatment approach in this setting is still unknown. The aim of our study was to evaluate the efficacy, safety, and outcomes of emergent surgical revascularization of acute extracranial ICA occlusion in patients with minor to severe ischemic stroke. METHODS: A retrospective analysis was performed using prospectively collected data of consecutive patients who underwent carotid thromboendarterectomy for symptomatic acute ICA occlusion during the period from January 2013 to December 2015...

The relationship between cholesterol level and hemorrhagic stroke is inconclusive. We hypothesized that low cholesterol levels may have association with intracerebral hemorrhage (ICH) severity at admission and 3-month outcomes. This study used data obtained from a multi-center stroke registry program in Taiwan. We categorized acute spontaneous ICH patients, based on their baseline levels of total cholesterol (TC) measured at admission, into 3 groups with <160, 160-200 and >200 mg/dL of TC. We evaluated risk of having initial stroke severity, with National Institutes of Health Stroke Scale (NIHSS) >15 and unfavorable outcomes (modified Rankin Scale [mRS] score >2, 3-month mortality) after ICH by the TC group...

BACKGROUND AND PURPOSE: Stroke-associated immunosuppression and inflammation are increasingly recognized as factors that trigger infections and thus, potentially influence the outcome after stroke. Several studies demonstrated that elevated neutrophil-to-lymphocyte ratio (NLR) is a significant predictor of adverse outcomes in patients with ischemic stroke. However, little is known about the impact of NLR on short-term mortality in intracerebral hemorrhage (ICH). METHODS: This observational study included 855 consecutive ICH-patients...

Intracerebral hemorrhage (ICH) is a devastating disease without effective treatment. After ICH, the immediate infiltration of leukocytes and activation of microglia are accompanied by a rapid up-regulation of translocator protein 18 kDa (TSPO). TSPO ligands have shown anti-inflammatory and neuroprotective properties in models of CNS injury. In this study, we determined the impact of a TSPO ligand, etifoxine, on brain injury and inflammation in 2 mouse models of ICH. TSPO was up-regulated in Iba1(+) cells from brains of patients with ICH and in CD11b(+)CD45(int) cells from mice subjected to collagenase-induced ICH...

BACKGROUND: Spontaneous anticoagulation-related intracerebral hemorrhage accounts for up to a quarter of spontaneous intracerebral hemorrhage cases and is associated with higher hematoma volume and a worse outcome. Guidelines recommend rapid anticoagulant reversal but mode and timing are not specified and optimal strategy is uncertain. Variability in everyday practice is unknown. METHODS: An invitation to a web-based survey was sent to 85 Dutch stroke neurologists in different hospitals, with questions about importance, timing, and medical management of spontaneous anticoagulation-related intracerebral hemorrhage...

Intracerebral hemorrhage (ICH) frequently results in severe disabilities and high mortality. RGD-containing elastin-like polypeptide (REP), a modified elastin-like polypeptide (ELP), is a thermally responsive biopolymer. REP has high affinity for cells and is known to show non-immunotoxicity, -cytotoxicity, and -inflammatory responses. Here we found that administration of REP in the acute phase of the ICH rat model reduced the hematoma volume, decreased the number of activated microglia, attenuated the expression of von Willebrand Factor (vWF), and prevented the leakage of immunoglobulin G (IgG) into the cerebral parenchyma without any occlusion of intact microvessels...

BACKGROUND AND PURPOSE: As Chinese Asian populations have an increased risk of intracerebral hemorrhage (ICH) after intravenous tissue plasminogen activator (IV tPA), we aimed to design a rapid, clinically applicable risk scoring system to predict ICH and functional outcomes after IV tPA treatment in Asian ischemic stroke patients. METHODS: From January 2009 to December 2012, consecutive acute ischemic stroke patients treated with IV tPA recruited from the Stroke Registry in Chang Gung Healthcare System (SRICHS) in Taiwan and the National University Hospital of Singapore (NUHS) acute stroke database were used to create and validate a scoring system...
