Peripheral blood amyloid-ß involved in the pathogenesis of Alzheimer's disease via impacting on peripheral innate immune cells.

A key pathological factor of Alzheimer's disease (AD), the most prevalent form of age-related dementia in the world, is excessive ß-amyloid protein (Aß) in extracellular aggregation in the brain. And in the peripheral blood, a large amount of Aß is derived from platelets. So far, the causality between the levels of peripheral blood Aß and its aggregation in the brain, particularly the role of the peripheral blood Aß in the pathology of AD, is still unclear. And the relation between the peripheral blood Aß and tau tangles of brain, another crucial pathologic factor contributing to the pathogenesis of AD, is also ambiguous. More recently, the anti-Aß monoclonal antibodies are approved for treatment of AD patients through declining the peripheral blood Aß mechanism of action to enhance plasma and central nervous system (CNS) Aß clearance, leading to a decrease Aß burden in brain and improving cognitive function, which clearly indicates that the levels of the peripheral blood Aß impacted on the Aß burden in brain and involved in the pathogenesis of AD. In addition, the role of peripheral innate immune cells in AD remains mostly unknown and the results obtained were controversial. In the present review, we summarize recent studies on the roles of peripheral blood Aß and the peripheral innate immune cells in the pathogenesis of AD. Finally, based on the published data and our own work, we believe that peripheral blood Aß plays an important role in the development and progression of AD by impacting on the peripheral innate immune cells.

Discrepancy in clinical and laboratory profiles of NMOSD patients between AQP4 antibody positive and negative: can NMOSD be diagnosed without AQP4 antibody?

AQP4-IgG has been considered as the pathogenic factor leading to NMOSD. However, about 20-30% of patients lack AQP4-IgG. So far, all therapeutic medicines are ineffective for NMOSD patients without AQP4 IgG. Thus AQP4-IgG is the pathogenic factor of NMOSD has been suspected and challenged. In addition, lack of efficacy of immunotherapy in NMOSD without AQP4 IgG has been a serious problem in the neurology. Identifying the clinical and laboratory characteristics and diversities between NMOSD patients with and without AQP4-IgG can be helpful to further explore the pathogenesis of NMOSD and guide clinical treatment. This is a single-centre retrospective study in The First Hospital of Jilin University, China including 92 patients diagnosed as NMOSD from January 2013 to January 2015. The characteristics of clinic, blood, cerebrospinal fluid (CSF), and image between AQP4-IgG negative (AQP4-IgG-) and AQP4-IgG positive (AQP4-IgG+) NMOSDs were compared. Our results showed that in the AQP4-IgG+ group, the ratio of women to men was 5.55, while in AQP4-IgG- group was 1.54 (P = 0.0092). In the AQP4-IgG+ patients, the expanded disability status scale (EDSS) was from 0 to 8.5, with an average of 5.550 ± 0.25, and the AQP4-IgG- patients had the EDSS score from 0 to 9, with an average of 4.032 ± 0.36 (P = 0.0006), which mainly affected movement system (P < 0.05) and superficial sensory impairment (P < 0.05). In the AQP4-IgG+ group, the blood brain barrier (BBB) permeability (P = 0.0210) and myelin basic protein (MBP) were increased (P = 0.0310) when compared to AQP4-IgG- group. Higher level IL-17 was seen in AQP4-IgG+ group than AQP4-IgG- group (P= 0.0066). Our results demonstrated that the NMOSD with AQP4-IgG more likely occurred in women and presented more severe clinical symptoms as well as significant BBB damage and increased MBP and IL-17 in CSF and blood, respectively compared with NMOSD without AQP4-IgG group. The differences in clinical and laboratory profiles between NMOSD with and without AQP4-IgG indicate the heterogeneity of NMOSD, in which AQP4-IgG may not be the only pathogenic molecule. It is necessary to find more pathogenic factors and to explore the new pathogenesis of NMOSD and therapeutic methods in the future.

Rescue Strategy for Hemorrhagic Complication During Mechanical Thrombectomy and the Clinical Outcome.

PURPOSE: Hemorrhagic complications occasionally occur during mechanical thrombectomy and may lead to catastrophic outcomes. Therefore, remedial strategies require careful investigation. Herein, we aimed to evaluate a cohort of patients who experienced hemorrhage during endovascular procedures, the rescue methods used, and outcomes observed. METHOD: This prospective study included patients who had hemorrhagic complications observed on digital subtraction angiography (DSA) during mechanical thrombectomy, between October 2017 and October 2022, at a high-volume stroke center. Functional outcomes were assessed using the modified Rankin scale (mRS) score at a 90-day follow-up. The primary outcomes were favorable outcomes (mRS score: 0-2 points) and mortality rates. The secondary outcomes were rescue therapy success rates, according to extravasation observed on the final DSA, recanalization status, and causes of hemorrhage. RESULTS: From October 2017 to October 2022, 1537 patients with stroke received emergency endovascular therapy, and 1147 patients completed a 90-day follow-up. Hemorrhage was observed in 33 (2.1%) patients in the process of endovascular interventions. Eighteen (54.5%) cases of hemorrhage were caused by microwire or microcatheter perforation. Mechanical stretching of the vessel during stent retriever withdrawal resulted in 8 (24.2%) cases of hemorrhage. Nine (27.3%) instances of hemorrhage stopped after the reversal of heparin administration and introduction of blood pressure control measures. Further endovascular rescue treatment was performed in 11 patients. Intracranial inflation of the balloon for tamponade stopped 10 hemorrhages, and 1 patient underwent additional coil embolization. Fifteen (45.5%) patients died within 90 days after the procedure. Three (9.1%) patients recovered functional independence (mRS score: 0-2 points) within 90 days. CONCLUSION: Hemorrhage during mechanical thrombectomy is a rare but severe complication of acute ischemic stroke with high mortality and disability rates. Intracranial inflation of a balloon for tamponade can effectively stop extravasation. CLINICAL IMPACT: This paper described haemorrhagic events characterised by contrast extravasation in the procedure of mechanical thrombectomy due to various causes. Although this complication is rare, patients showed a high mortality and disability rate. There are limited reports available. We found self-limiting haemorrhage had a rather benign prognosis and balloon tamponade could effectively stop the extravasation and might reduce the death rate within 90d. The methods we adopted could be applied in the clinical practice and help neuro-interventionist cope with this complication more promptly and effectively.

Which glucose parameter best predicts poor outcome after mechanical thrombectomy for acute large vessel occlusion stroke?

BACKGROUND: Hyperglycaemia is related to adverse outcomes in patients with acute ischaemic stroke (AIS) treated with mechanical thrombectomy (MT). AIMS: To compare the predictive ability of admission blood glucose (ABG), fasting blood glucose (FBG) and glycated haemoglobin (HbA1c) in patients with acute large vessel occlusion (ALVO) stroke undergoing MT. METHODS: The study retrospectively analysed the data of 329 consecutive acute stroke patients treated with MT. Multivariate logistic regression analysis was performed to investigate the predictors of poor functional outcome. Receiver operating characteristic (ROC) analysis was performed to identify the predictive ability of ABG, FBG and HbA1c for poor functional independence in patients with ALVO stroke undergoing MT. In addition, subgroup analyses were performed for both diabetic and non-diabetic patients. RESULTS: Multiple logistic regression analysis demonstrated that ABG and FBG were independent predictors of 3-month poor functional outcome; however, HbA1c could not predict poor functional outcome. ROC analysis showed that FBG has a higher predictive ability than ABG (areas under the ROC curve (AUC): 0.689 vs 0.624; P = 0.037) and HbA1c (AUC: 0.689 vs 0.541; P < 0.001) for poor function outcome. CONCLUSIONS: ABG and FBG are independent predictors of poor functional outcome in patients with AIS undergoing MT, and FBG has a higher predictive ability than ABG and HbA1c.

Cervical artery dissection-an easily neglected cause of stroke: a case report.

BACKGROUND: In recent years, the incidence of stroke has gradually increased in young people. There are many reasons causing stroke, including atherosclerosis, artery embolization, and cervical artery dissection and so on. However, cervical artery dissection is a major cause of stroke in young people. We present a case of ischemic stroke caused by dissection, whose distal vascular occlusion due to detachment of the thrombosis in the right internal carotid artery. CASE PRESENTATION: A 33-year-old male patient was admitted to the hospital because of stroke. Imaging examination showed that there was no visualization of the right middle cerebral artery and there were a large number of mural thrombus in the C1 segment of the right internal carotid artery. After emergency surgery, the patient had vascular recanalization and the symptoms were significantly improved. Magnetic resonance imaging showed a high signal in the C1 segment of the right internal carotid artery, the abnormal signal disappeared after antiplatelet therapy. CONCLUSIONS: When a patient has symptoms of stroke, we need to explore the root cause of stroke. Especially in young people, cervical artery dissection is an important reason that can't be ignored. Through review and analysis of this case, we hope to improve the understanding of radiologists and clinicians about the cervical artery dissection, reduce the rate of misdiagnosis, and improve patients' prognosis.

Venous sinus stenting improves cerebral autoregulation in a patient with venous sinus stenosis: a case report.

BACKGROUND: Venous sinus stenosis (VSS) is a type of cerebral venous vascular disease. Cerebral autoregulation is an indicator of cerebral arterial function. The cerebral circulatory system is composed of the venous system and arterial system. Impaired venous function may affect arterial function. Thus, cerebral venous stenosis may influence cerebral autoregulation. CASE PRESENTATION: In this case, a 50-year-old woman with transient blindness and headache was admitted to the hospital. The patient was diagnosed with VSS. A stent was placed at the stenosis. The stent released the intravenous pressure and remitted the patient's symptoms. Measurements of dynamic cerebral autoregulation (dCA) were performed at 3 time points: before stenting, after stenting, and 3 months later. The dCA gradually improved after stenting. CONCLUSION: VSS may have an influence on cerebral autoregulation, and effective treatment improves cerebral autoregulation in patients with VSS.

The Therapeutic Effects of Endovascular Therapy with mTICI2b and 3 Recanalization for Acute Anterior Circulation Stroke Patients.

BACKGROUND AND PURPOSE: Modified Thrombolysis in Cerebral Infarction (mTICI)2b/3 has been considered the criterion for successful reperfusion in endovascular treatment. This study aimed to compare the therapeutic safety and efficacy of mTICI2b and mTICI3 recanalization, and to analyze the factors related to outcomes in everyday clinical practice. MATERIALS AND METHODS: This is a single-center retrospective analysis of 224 patients who underwent successful thrombectomy (achieving a mTICI score ≥2b). The primary outcomes included a modified Rankin score (mRS) of 0-2 at 90-day, mortality, and symptomatic intracranial hemorrhage. RESULTS: A total of 111 patients achieved mTICI2b status (49.6%), and 113 achieved mTICI3 status (50.4%). The comparison between mTICI2b and 3 reperfusions showed no differences in short-term outcomes, 90-day mRS, complications, and mortality. There was a trend toward more passes in mTICI2b patients, although the difference was not significant. The univariate analysis showed that poor outcomes after endovascular treatment were associated with older age, previous history of coronary heart disease, atrial fibrillation, diabetes, tandem occlusions, high National Institutes of Health Stroke Scale (NIHSS) score on admission, and general anesthesia. A previous history of coronary heart disease, a high NIHSS score on admission, and the use of general anesthesia were independent factors that affected the therapeutic effects. CONCLUSION: The superiority (efficacy and safety) of mTICI3 reperfusion was not significant compared with that of mTICI2b reperfusion. Prolonged efforts to achieve mTICI3 after achieving mTICI2b should be considered prudently for those with difficulty achieving 100% reperfusion.

Different EPHX1 methylation levels in promoter area between carbamazepine-resistant epilepsy group and carbamazepine-sensitive epilepsy group in Chinese population.

BACKGROUND: Epigenetics underlying refractory epilepsy is poorly understood. DNA methylation may affect gene expression in epilepsy patients without affecting DNA sequences. Herein, we investigated the association between Carbamazepine-resistant (CBZ-resistant) epilepsy and EPHX1 methylation in a northern Han Chinese population, and conducted an analysis of clinical risk factors for CBZ-resistant epilepsy. METHODS: Seventy-five northern Han Chinese patients participated in this research. 25 cases were CBZ-resistant epilepsy, 25 cases were CBZ-sensitive epilepsy and the remaining 25 cases were controls. Using a CpG searcher was to make a prediction of CpG islands; bisulfite sequencing PCR (BSP) was applied to test the methylation of EPHX1. We then did statistical analysis between clinical parameters and EPHX1 methylation. RESULTS: There was no difference between CBZ-resistant patients, CBZ-sensitive patients and healthy controls in matched age and gender. However, a significant difference of methylation levels located in NC_000001.11 (225,806,929.....225807108) of the EPHX1 promoter was found in CBZ-resistant patients, which was much higher than CBZ-sensitive and controls. Additionally, there was a significant positive correlation between seizure frequency, disease course and EPHX1 methylation in CBZ-resistant group. CONCLUSION: Methylation levels in EPHX1 promoter associated with CBZ-resistant epilepsy significantly. EPHX1 methylation may be the potential marker for CBZ resistance prior to the CBZ therapy and potential target for treatments.

The Detection of the Negative Effects of Interictal Epileptiform Discharges on Cognition: An Event-Related Potential Study.

Evidence from a neuropsychological test revealed that interictal epileptiform discharges (IEDs) may have significant impact on cognitive performance. Sometimes, neuropsychological tests may not be sensitive to detection of mild cognitive changes. We applied P300 and mismatch negativity (MMN) to detect mild cognitive changes caused by small amount of IEDs. Sixty-seven adult epilepsy patients and participants were divided into six groups according to different IEDs index. The patients with IED index greater than 7.5% showed longer latency and lower amplitude in the test of P300 and MMN than patients with IED index less than 7.5%, which indicated mild impaired cognitive function. The negative effect of IED index greater than 10% on cognitive has been found by neuropsychological test, whereas the mild negative effect of IED index greater than 7.5% has only been found by P300 and MMN. So, P300 and MMN may be more sensitive than neuropsychological tests to detect mild cognitive impairment caused by IEDs.

Gut Microbiota in Multiple Sclerosis and Experimental Autoimmune Encephalomyelitis: Current Applications and Future Perspectives.

The gut environment and gut microbiome dysbiosis have been demonstrated to significantly influence a range of disorders in humans, including obesity, diabetes, rheumatoid arthritis, and multiple sclerosis (MS). MS is an autoimmune disease affecting the central nervous system (CNS). The etiology of MS is not clear, and it should involve both genetic and extrinsic factors. The extrinsic factors responsible for predisposition to MS remain elusive. Recent studies on MS and its animal model, experimental autoimmune encephalomyelitis (EAE), have found that gastrointestinal microbiota may play an important role in the pathogenesis of MS/EAE. Thus, gut microbiome adjustment may be a future direction of treatment in MS. In this review, we discuss the characteristics of the gut microbiota, the connection between the brain and the gut, and the changes in gut microbiota in MS/EAE, and we explore the possibility of applying microbiota therapies in patients with MS.

Clapping-surpressed focal spikes in EEG may be unique for the patients with rett syndrome : a case report.

BACKGROUND: Rett syndrome is a severe neurodevelopmental disorder that primarily affects females. Typical features include a loss of purposeful hand skills, development of hand stereotypies, loss of spoken language, gait abnormalities, and acquired microcephaly. However, Rett syndrome hasn't been recognized by clinical doctors at the early stage. So we need to find some special characters. CASE PRESENTATION: We reported a Chinese case of Rett syndrome, exhibiting continuous centrotemporal spikes in EEG with paroxysmal suppression by hand stereotypies (hand clapping). The child, female, 4 years old, presented with a significant regression in her spoken language skills, hand stereotypies (hand clapping and hand wringing), a wider based gait with difficulties in balance, repeated abnormal behaviors (bruxism and head banging). With her clinical-history, Rett syndrome was suspected and genetic testing with mutation in MECP2 confirmed the diagnosis. Her EEG showed slow acticity in background and revealed a specific feature that continuous centrotemporal spikes can be suppressed by the repeated hand clapping. And when the hand stopped, the spikes reoccured again. CONCLUSIONS: This unique EEG signature has rarely been reported, which will expand the spectrum of EEG abnormalities in Rett syndrome.

Revascularization of vertebrobasilar artery occlusion at the chronic stage.

We describe a patient who underwent intracranial angioplasty and Solitaire stent placement for recanalization of a vertebrobasilar artery occlusion 2 months after symptom onset. Computed tomography angiography and digital subtraction angiography showed that both vertebral arteries and the proximal basilar artery were occluded. Balloon angioplasty was performed on a segment of the occluded left vertebral artery and basilar artery, followed by successful detachment of one Solitaire stent. Repeat angiography showed near normal patency of the left vertebrobasilar artery. The patient`s symptoms improved significantly, and postoperative transcranial Doppler sonography 3 months later showed no evidence of in-stent restenosis.

Comprehensive classifications for the endovascular recanalization of vertebral artery stump syndrome.

Background: and purpose: To share our single-center vertebral artery stump syndrome (VASS) treatment experience and assess the role of comprehensive classification based on anatomic development, proximal conditions, and distal conditions (PAD). Materials and methods: Data were retrospectively collected from patients who underwent endovascular thrombectomy (EVT) at the Stroke Center of the First Hospital of Jilin University between January 2016 and December 2021. Among patients with acute ischemic stroke in the posterior circulation, those with acute occlusion of the intracranial arteries and occlusion at the origin of the vertebral artery confirmed by digital subtraction angiography were selected. The clinical data were summarized and analyzed. Results: Fifteen patients with VASS were enrolled in the study. The overall success rate of surgical recanalization was 80%. The successful proximal recanalization rate was 70.6%, and the recanalization rates for P1, P2, P3, and P4 were 100%, 71.4%, 50%, and 66.67%, respectively. The mean operation times for the A1 and A2 types were 124 and 120 â€‹min, respectively. The successful distal recanalization rate was 91.7%, and the recanalization rates for types D1, D2, D3, and D4 were 100%, 83.3%, 100%, and 100%, respectively. Five patients experienced perioperative complications (incidence rate: 33.3%). Distal embolism occurred in three patients (incidence rate: 20%). No dissection or subarachnoid hemorrhage occurred in any patient. Conclusion: EVT is a technically feasible treatment for VASS, and comprehensive PAD classification can, to a certain extent, help initially estimate the difficulty of surgery and provide guidance for interventional procedures.

Associations between NIHSS sub-item scores and prognosis and intracranial hemorrhage after endovascular therapy for acute anterior circulation ischemic stroke.

Purpose: The relationship between sub-item scores on the National Institutes of Health Stroke Scale (NIHSS) scores and prognosis and intracranial hemorrhage in patients with acute ischemic stroke undergoing endovascular treatment (EVT) has been insufficiently studied. The aim of this study was to investigate the correlation between NIHSS sub-item scores, prognosis, and intracranial hemorrhage. Methods: This study included patients with acute anterior circulation ischemic stroke undergoing EVT between February 2019 and April 2022. The outcomes included functional independence, defined as a modified Rankin Scale (mRS) score ≤ 2 at 3 months after EVT, intracranial hemorrhage within 24 h after EVT, and mortality within 3 months. A multivariate regression analysis was performed, including NIHSS sub-item scores and other adjusted variables. Results: A total of 568 patients were enrolled. Of the 568 patients, 239 (45%) achieved functional independence at 3 months after EVT. The median age in this group was 63 years (IQR 52-69) and 176 (73.6%) were male patients. Intracranial hemorrhage within 24 h after EVT occurred in 170 (30%) patients. The median age in this group was 65 years (IQR 56-71) and 105 (61.8%) were male patients. In a multivariate analysis adjusted for age, gender, and factors with a value of p of <0.05, the NIHSS limb movement sub-item score was strongly associated with prognosis at 3 months (OR 0.833, 95% CI 0.758-0.915) and intracranial hemorrhage within 24 h after EVT (OR 1.161, 95% CI 1.037-1.300). Conclusion: Higher limb movement sub-item scores on the NIHSS were independently associated with a poorer prognosis at 3 months and a higher rate of intracranial hemorrhage within 24 h after EVT among patients with acute anterior circulation ischemic stroke.

Progress in treatment of neuromyelitis optica spectrum disorders (NMOSD): Novel insights into therapeutic possibilities in NMOSD.

Neuromyelitis optica spectrum disorder (NMOSD) is a rare autoimmune inflammatory demyelinating disorder of the central nervous system (CNS), which is a severely disabling disorder leading to devastating sequelae or even death. Repeated acute attacks and the presence of aquaporin-4 immunoglobulin G (AQP4-IgG) antibody are the typical characteristics of NMOSD. Recently, the phase III trials of the newly developed biologicals therapies have shown their effectiveness and good tolerance to a certain extent when compared with the traditional therapy with the first- and second-line drugs. However, there is still a lack of large sample, double-blind, randomized, clinical studies to confirm their efficacy, safety, and tolerability. Especially, these drugs have no clear effect on NMOSD patients without AQP4-IgG and refractory patients. Therefore, it is of strong demand to further conduct large sample, double-blind, randomized, clinical trials, and novel therapeutic possibilities in NMOSD are discussed briefly here.

Impact of Anti-amyloid-ß Monoclonal Antibodies on the Pathology and Clinical Profile of Alzheimer's Disease: A Focus on Aducanumab and Lecanemab.

Alzheimer's disease (AD) is the most prevalent form of age-related dementia in the world, and its main pathological features consist of amyloid-ß (Aß) plaque deposits and neurofibrillary tangles formed by hyperphosphorylated tau protein. So far, only a few AD treatments approved have been applied in the clinic, but the effects of these drugs are limited only for partial symptomatic relief to patients with AD and are unable to alter AD progression. Later, all efforts for AD treatments with targeting the pathogenic factors were unsuccessful over the past decades, which suggested that the pathogenesis of AD is complex. Recently, disease-modifying therapies (DMTs) that can change the underlying pathophysiology of AD, with anti-Aß monoclonal antibodies (mabs) (e.g., aducanumab, bapineuzumab, gantenerumab, solanezumab, and lecanemab) have been developed successively and conducted in clinical trials based on the theory that a systemic failure of cell-mediated Aß clearance contributes to AD occurrence and progression. In the review, we summarized recent studies on the therapeutic effects and clinical trial results of these mabs in patients with AD. Specifically, we focused on the discussion of the impact of aducanumab and lecanemab on AD pathology and clinical profiles. The review provides a possible evidence for applying immunotherapy with anti-Aß mabs in AD and analyzes lessons learned from these clinical trials in order to further study the therapeutic and adverse effects of these anti-Aß mabs on AD.

Role of Adaptive Immune and Impacts of Risk Factors on Adaptive Immune in Alzheimer's Disease: Are Immunotherapies Effective or Off-Target?

The pathogenesis of Alzheimer's disease (AD) is complex. Still it remains unclear, which resulted in all efforts for AD treatments with targeting the pathogenic factors unsuccessful over past decades. It has been evidenced that the innate immune is strongly implicated in the pathogenesis of AD. However, the role of adaptive immune in AD remains mostly unknown and the results obtained were controversial. In the review, we summarized recent studies and showed that the molecular and cellular alterations in AD patients and its animal models involving T cells and B cells as well as immune mediators of adaptive immune occur not only in the peripheral blood but also in the brain and the cerebrospinal fluid. The risk factors that cause AD contribute to AD progress by affecting the adaptive immune, indicating that adaptive immunity proposes a pivotal role in this disease. It may provide a possible basis for applying immunotherapy in AD and further investigates whether the immunotherapies are effective or off-target?

Comparisons of clinical phenotype, radiological and laboratory features, and therapy of neuromyelitis optica spectrum disorder by regions: update and challenges.

Neuromyelitis optica spectrum disorder (NMOSD) is an inflammatory demyelinating disease of the central nervous system (CNS) associated with autoantibody (ab) to aquaporin-4 (AQP4). There is obvious variation between regions and countries in the epidemiology, clinical features and management in NMOSD. Based on published population-based observation and cohort studies, the different clinical pattern of NMOSD has been seen in several geographical regions and some of these patients with NMOSD-like features do not fully meet the current diagnostic criteria, which is needed to consider the value of recently revised diagnostic criteria. At present, all treatments applied in NMOSD have made great progress, however, these treatments failed in AQP4 ab negative and refractory patients. Therefore, it is necessary to turn into an innovative idea and to open a new era of NMOSD treatment to develop novel and diverse targets and effective therapeutic drugs in NMOSD and to conduct the trails in large clinical samples and case-control studies to confirm their therapeutic effects on NMOSD in the future, which still remain a challenge.

Basilar artery on computed tomography angiography score and clinical outcomes in acute basilar artery occlusion.

OBJECTIVES: This study aimed to evaluate the safety and efficacy of mechanical thrombectomy (MT) in patients with acute basilar artery occlusion (BAO) based on the baseline Basilar Artery on Computed Tomography Angiography (BATMAN) score. METHODS: We selected patients from the BASILAR study and analyzed the effects and safety of standard medical therapy (SMT) and MT for patients with documented BATMAN scores. The patients were subgrouped according to their BATMAN score (0-3, 4-6, and 7-10). The primary outcome was a favorable functional outcome (modified Rankin Scale [mRS] ≤ 3) and mortality after 90 days. RESULTS: This study included 828 patients: 337 with poor BATMAN scores (0-3), 386 with moderate BATMAN scores (4-6), and 105 with good BATMAN scores (7-10). MT was associated with favorable functional outcomes in the poor (adjusted odds ratio [aOR], 11.96; 95% confidence interval [CI], 2.58-55.43; P = 0.002), moderate (aOR, 4.66; 95% CI, 2.11-10.28; P < .001), and good (aOR, 7.71; 95% CI, 2.20-27.02; P = 0.001) BATMAN score subgroups. MT was also associated with low mortality rates in the poor (aOR, 0.10; 95% CI, 0.04-0.27; P < 0.001) and moderate (aOR, 0.31; 95% CI, 0.16-0.57; P = 0.002) BATMAN score subgroups. The BATMAN score was significantly associated with favorable outcomes in both the SMT (aOR, 1.44; 95% CI, 1.08-1.93; P = 0.014) and MT (aOR, 1.31; 95% CI, 1.20-1.44; P < 0.001) groups. CONCLUSION: Higher BATMAN scores were associated with improved prognosis and lower mortality rates after 3 months. MT was associated with improved outcomes in patients with low BATMAN scores despite their worse overall outcomes. UNIQUE IDENTIFIER: ChiCTR1800014759, 2018/02/03.
