Cytokine Registry Database of Stroke Patients

Start date: October 5, 2017
Phase: N/A
Study type: Observational [Patient Registry]

Various molecules (cytokines: interleukins, interferons and neural proteins) found in human and animal blood are reported to be elevated in acute stroke (Ischemic and hemorrhagic). Cytokines can be pro-inflammatory or anti-inflammatory. There are studies confirming level changes in serum of humans in the setting of several rheumatologic and cardiovascular diseases. As new molecular markers (cytokines and neural tissue markers) are established in scientific literature, stroke scientists are interested to evaluate the role of these in the pathophysiology of stroke. Investigators intend to study the role of these molecules in the development of stroke. Acute stroke treatment has advanced considerably in the last 10 years with the establishment of comprehensive stroke centers and approval of neuro-interventional techniques. However, the molecular advancement in stroke pathogenesis has yet to reach a milestone in the world of stroke treatment. In our opinion, creating a database of acute stroke patients containing all pertinent medical demographics and clinical information along with the laboratory data, molecular levels of pertinent cytokines/neural factors from consenting patients, will help us define and delineate the most relevant molecules that are altered in acute stroke patients and can help us further improve us understanding of the role of these in acute stroke and thereby hopefully help in the improvement of our understanding and management of stroke. Moreover, analyzing the cytokines in stroke and ICH patients would help understand their role in the acute phase, which may become potential therapeutic adjuncts for tPA and endovascular thrombectomy.

Contrast Enhanced Sonothrombolysis and Sonolysis in Stroke - a Swedish Study (CE-5S)

Start date: October 5, 2017
Phase: Phase 3
Study type: Interventional

Patients with acute ischemic stroke in anterior circulation within 4,5 hours of symptom onset, has a bone window and Trombolysis In Brain Ischemia (TIBI) <=4 in a relevant artery eligible. Both patients receiving thrombolysis and those who do not due to contraindications such as anticoagulation or recent surgery are enrolled, but into different study arms (CE-5S A for thrombolysis and B for non-thrombolysis); the decision to treat with thrombolysis or not is done according to clinical routine. All included patients are randomized to receive transcranial ultrasound and SonoVue-infusion or sham-ultrasound and placebo; i.e. in CE-5S A, contrast enhanced sonothrombolysis is compared to thrombolysis and in CE-5S B, contrast enhanced sonolysis is compared with conservative management. Main outcome is improvement in National Institute of Health Stroke Scale (NIHSS) at 24 hours compared to baseline. Main safety outcome is symptomatic intracerebral haemorrhage.

Prognostic Value of Carotid CEUS in Acute Ischemic Stroke Patients

Start date: August 9, 2017
Phase: N/A
Study type: Observational [Patient Registry]

Contrast-enhanced ultrasound(CEUS) of carotid artery plaque is a novel method that enabled direct visualization of neovessels in the vulnerable plaque. Plaque enhancement with CEUS showed correlation with the histologic density of neovessels within the carotid plaque and the previous cardiovascular events. Vulnerable plaques with a high risk of thromboembolic complications and rapid progression is associated with acute ischemic stroke. The prognostic value of vulnerable carotid artery plaque depicted with CEUS has not been fully investigated. The purpose of this study is to define prognostic value of plaque enhancement on carotid CEUS in acute stroke patients. Research question is; in acute ischemic stroke patients with ipsilateral carotid plaque as probable etiology of stroke, is the presence of carotid plaque enhancement on CEUS independent predictor of future stroke.

NCT ID: NCT03281590 Recruiting - Stroke Clinical Trials

Stroke and Cerebrovascular Diseases Registry

Start date: September 6, 2017
Phase: N/A
Study type: Observational [Patient Registry]

This is a single institutional registry database for the patients with stroke and cerebrovascular diseases. Stroke is the fifth leading cause of death in the United States. Despite extensive research, most of the patients die or suffer from varying degree of post-stroke disabilities due to neurologic deficits. This registry aims to understand the disease and examine the disease dynamics in the local community.

NCT ID: NCT03258983 Completed - Ischemic Stroke Clinical Trials

Alpha-linolenic Acid and the Risk of ASCVD

Start date: November 24, 1993
Phase: N/A
Study type: Observational

Background: The plant-derived omega-3 fatty acid alpha-linolenic acid (ALA, 18:3-n-3) may reduce the risk of atherosclerotic cardiovascular disease, including incident myocardial infarction, ischemic stroke and peripheral artery disease. However, the results of previous studies have been inconsistent. Objectives: To investigate the associations between dietary intake of ALA, adipose tissue content of ALA, and the risk of the major atherosclerotic cardiovascular diseases incident myocardial infarction, ischemic stroke and subtypes, and peripheral artery disease. Methods: This project will be based on data from the Danish cohort study Diet, Cancer and Health which consisted of 57,053 men and women at recruitment between 1993 and 1997. Dietary intake of ALA will be assessed using a validated semiquantitative food-frequency questionnaire and adipose tissue content will be determined with the use of gas chromatography analyses of adipose tissue biopsies collected at baseline. Also, detailed information on lifestyle factors, medical history and anthropometri was collected at baseline. Incident cases have been identified through national registries and the diagnoses have previously been validated. Analyses of dietary intake of ALA will be analysed using a traditional cohort design, whereas analyses on adipose tissue content of ALA will be analysed based on a case-cohort design. Hazard ratioes with 95% confidence intervals will be used to describe the associations between the exposure variables and the outcome variables of interest.

NCT ID: NCT03247036 Completed - Ischemic Stroke Clinical Trials

Long-Term Survival After Ischaemic Stroke: Ebrictus Study

Start date: January 13, 2017
Phase: N/A
Study type: Observational [Patient Registry]

A number of large trials have confirmed the benefits of thrombolysis in acute stroke, but there are gender differences. The authors sought to examine the relationship between sex and outcome after thrombolysis. Previous reports [1-6] concerning sex-related differences in stroke management and outcome are inconsistent and sometimes difficult to interpret, and so the reasons for gender disparities in stroke outcome have remained unclear. Functional outcomes and quality of life after stroke are consistently poorer in women despite adjustment for baseline differences in age and prestroke function, and the fact that comorbidities and clinical outcomes were not different between women and men [3, 7] . Once the reasons for these differences are better understood, intervention might be possible to help provide the best care for all patients. This work is a continuation and extension of the Ebrictus Study [8-10] . Prior work has suggested sex-based differences in thrombolytic therapy in subjects with acute stroke [11] .The authors will explore whether sex might modify the effect of thrombolysis on survival and functional outcomes in patients with acute ischemic stroke [12] beyond the usually evaluated time period of 6 months after stroke and compared this with the group without thrombolytic treatment.
