Filter by:Acute brain injury due to traumatic brain injury (TBI), intracerebral haemorrhage (ICH), and aneurysmal subarachnoid haemorrhage (SAH) carries a high morbidity and mortality, in part due to the development of secondary brain injury. The mechanisms behind secondary brain injury are incompletely understood, but oxidative/nitrosative stress and disturbances in the metabolism of the vasodilator nitric oxide (NO) are believed to be involved. The aim of the present study is to characterise systemic changes in markers of oxidative/nitrosative stress and NO metabolism in the early phase after acute brain injury, and to examine their relationship to clinical course, neurological outcome, and mortality.
The CASES-TCM study is a prospective, multicenter, observational study, which will enroll 20,000 patients with acute stroke (ischemic stroke or intracerebral hemorrhage) within 7 days of symptom onset. This study attempts to depict major clinical characteristics of acute stroke in patients with Chinese medicine treatment and to explore any difference compared with other non-Chinese medicine use cohorts and the effectiveness and safety of Chinese medicine.
The overall goal of the DISCOVERY study is to better understand what factors contribute to changes in cognitive (i.e., thinking and memory) abilities in patients who experienced a stroke. The purpose of the study is to help doctors identify patients at risk for dementia (decline in memory, thinking and other mental abilities that significantly affects daily functioning) after their stroke so that future treatments may be developed to improve outcomes in stroke patients. For this study, a "stroke" is defined as either (1) an acute ischemic stroke (AIS, or blood clot in the brain), (2) an intracerebral hemorrhage (ICH, or bleeding in the brain), (3) or an aneurysmal subarachnoid hemorrhage (aSAH, or bleeding around the brain caused by an abnormal bulge in a blood vessel that bursts). The investigators hypothesize that: 1. The size, type and location of the stroke play an important role in recovery of thinking and memory abilities after stroke, and pre-existing indicators of brain health further determine the extent of this recovery. 2. Specific stroke events occurring in individuals with underlying genetic or biological risk factors can cause further declines in brain heath, leading to changes in thinking and memory abilities after stroke. 3. Studying thinking and memory alongside brain imaging and blood samples in patients who have had a stroke allows for earlier identification of declining brain health and development of individualized treatment plans to improve patient outcomes in the future.
The investigators conduct this study to investigate whether oral administration of Dimethyl Fumarate, a Food and Drug Administration-approved drug for multiple sclerosis, is safe and effective in alleviating PHE and neurologic deficits in patients with ICH.
This is a retrospective observational study to investigate the clinical, analytical and neuroimaging data generated during routine clinical management of intracerebral hemorrhage. The study will review the data from about 500 patients attended during the last ten years in the Neurology Department of Hospital Parc Taulí de Sabadell. The aim is to measure the size of the lesion in neuroimage (TC and MRI), the edema, the alterations in diffusion weighted images and to correlate this data with clinical parameters and analytical measurements. With this approach investigators plan to investigate the incidence of hematoma growth, the role of perilesional edema and diffusion changes, and the relation between neuroimaging findings and clinical outcome. The study also try to establish significant correlations between clinical and analytical data, the clinical outcome and and the magnitude of changes in neuroimaging.
Currently, the main treatment method for Intracerebral Hemorrhage (ICH) is medication or surgery. However, the effectiveness of medicines is moderate and there are several side effects. In this clinical trial, we would like to enhance the protein levels of brain derived neurotrophic factor in the brain by the transcranial ultrasound stimulation (TUS). By this technology, the symptoms of ICH could be alleviated and the side effects of medicines might be avoided. Preclinical trials have also shown that low-intensity pulsed ultrasound can alleviate the degree of neuroinflammation, neurodegeneration and significantly improve motor and cognitive deficits after brain injury. The purpose of this clinical trial is to evaluate the safety and feasibility of TUS for the treatment of patients with hypertensive intracerebral hemorrhage. The primary safety assessment indexes are brain magnetic resonance imaging (MRI) and brain magnetic resonance angiography (MRA). The secondary safety assessment indexes include weight, vital signs, electrocardiogram, general blood biochemical tests, adverse reaction events, and concurrent drug tracking. The feasibility assessment includes blood specific biomarker expression and neurological function & quality of life scales.
Brain injury after spontaneous intracerebral hemorrhage results from pathophysiologic responses in the brain parenchyma due to hematoma formation, release of clot components, and surrounding edema. Inflammatory cascade activation in the perihematomal brain parenchyma has been implicated in the pathogenesis of secondary brain injury. Statins have been identified as a potential neuroprotective agent that targets the inflammatory response to intracerebral hemorrhage. In preclinical studies, statin treatment in animal intracerebral hemorrhage models has consistently demonstrated neuroprotective and recovery enhancement effects. Clinical investigations in humans reported better patient outcomes associated with statin use in patients with intracerebral hemorrhage, including reduced perihematomal edema, lower mortality rates, and improved functional outcomes.
The primary objective of this trial is to provide preliminary safety data of minimally invasive endoscopic surgery using the Axonpen™ system for spontaneous intracerebral hemorrhage (ICH). The effectiveness of the Axonpen™ system in early hematoma removal and the surgical impact on subject's functional recovery will also be evaluated. The Axonpen™ system, consisting of a neuroendoscope (Axonpen) and a monitor (Axonmonitor), is cleared by FDA and indicated for the illumination and visualization of intracranial tissue and fluids and the controlled aspiration of tissue and/or fluid during surgery of the ventricular system or cerebrum.
Spontaneous intracerebral haemorrhage (sICH) is the deadliest stroke subtype yearly affecting over 6000 patients in the Netherlands. Treatment options are very limited. Inflammation plays a vital role in the development of sICH-related secondary brain injury (SBI). Within 4 hours after sICH onset, blood components and thrombin induce the release of cytokines and other inflammatory molecules, with subsequent microglial activation, blood brain barrier (BBB) damage and the formation of perihaematomal oedema (PHO). Among the released cytokines, interleukin 1 beta (IL-1β) has a pivotal role. Recombinant human interleukin-1 receptor antagonist (IL-1Ra, anakinra) effectively antagonizes IL-1β through competitive binding to the IL-1 receptor. Anakinra is available for treatment of rheumatoid arthritis, other inflammatory diseases and has been studied in acute sepsis. We hypothesize that anakinra safely reduces SBI after sICH, and that its effect is dose-dependent. Objective: To determine the effect of high-dose versus low-dose anakinra compared to standard medical management on oedema extension distance (OED) determined with MRI on day 7±1. Second, to study the safety profile of anakinra. Furthermore, to assess its effect on 1) serum inflammatory markers IL-1β, IL-6, hsCRP, neutrophil and total white blood cell counts at day 1, 3 and 7 compared to baseline; 2) DCE-MRI measurement of BBB transfer constant (Ktrans) on day 7±1, and; 3) to estimate an effect on functional outcome in patients with sICH. Study design: Multicentre, prospective, randomized, three-armed (1:1:1) trial with open label treatment and blinded end-point assessment (PROBE design) . Study population: 75 patients with supratentorial sICH admitted within 8 hours after symptom onset. Intervention: Patients will receive anakinra in either a high dose (loading dose 500mg i.v., followed by infusion with 2mg/kg/h over 3 days; n=25) or in a low dose (loading dose 100mg s.c.., followed by subcutaneous administration of 100mg twice a day for 3 days; n=25), started within 8 hours of symptom onset. The control group (n=25) will receive standard medical management. Main study parameters/endpoints: Primary objective is to test whether anakinra reduces subacute perihaematomal oedema after sICH, measured as OED on MRI at day 7±1.
This study is a multicenter, prospective, open-label, endpoint-blind, randomized controlled study.Patients receiving surgical treatment for SICH were divided into groups using the random machine method. In addition to conventional treatment for spontaneous intracerebral hemorrhage, patients in the group of early initiation of antiplatelet therapy were given conventional dose of aspirin (100mg, qd) antiplatelet therapy starting from the 3rd day after surgery.An independent group of investigators evaluated cardiac, cerebral and peripheral vascular events and bleeding events at four different time points.To evaluate the benefits and safety of early postoperative initiation of antiplatelet therapy in patients with spontaneous intracerebral hemorrhage.
