Background and Purpose: At present, stroke patients receiving intravenous thrombolysis (IVT) undergo monitoring of their neurological status and vital signs every 15 minutes for the first 2 hours, every 30 minutes for the next 6 hours, and every hour thereafter up to 24 hours post-IVT. The present study sought to prospectively evaluate whether post-IVT stroke patients with low risk for complications may safely be cared for utilizing a novel low-intensity monitoring protocol. Methods: In this pragmatic, prospective, single-center, open-label, single-arm safety study, we enrolled 35 post-IVT stroke patients. Adult patients were eligible if their NIH Stroke Scale (NIHSS) was less than 10 at the time of presentation, and if they had no critical care needs by the end of the IVT infusion. Patients underwent a low-intensity monitoring protocol during the first 24 hours after IVT. The primary outcome was need for a critical care intervention in the first 24 hours after IVT. Results: The median age was 54 years (range: 32-79), and the median pre-IVT NIHSS was 3 (interquartile range [IQR]: 1-6). None of the 35 patients required transfer to the intensive care unit or a critical care intervention in the first 24 hours after IVT. The median NIHSS at 24 hours after IVT was 1 (IQR: 0-3). Four (11.4%) patients were stroke mimics, and the vast majority was discharged to home (82.9%). At 90 days, the median NIHSS was 0 (IQR: 0-1), and the median modified Rankin Scale was 0 (range: 0-6). Conclusion: Post-IVT stroke patients may be safely monitored in the setting of a low-intensity protocol.

Introduction. Atrial fibrillation is associated with an increased risk of ischemic stroke. The benefit of intravenous thrombolysis in patients with acute ischemic stroke and atrial fibrillation is still unclear. The aim of the study was to assess and compare the effects of intravenous thrombolysis in stroke patients with and without atrial fibrillation. Material and Methods. We analyzed stroke patients who were treated with intravenous thrombolysis. Patients were divided into two groups according to the presence of atrial fibrillation. Demographic, clinical and radiological characteristics of patients were compared between the two groups. The treatment efficacy was evaluated in relation to the improvement of neurological status after 24 hours, and functional recovery after three months. Binary logistic regression was used to evaluate predictors of outcome. Results. From a total of 188 patients, 39.4% presented with atrial fibrillation. Patients with atrial fibrillation were older (69.4 vs. 62.6 years; p <0.0001), with female predominance (43.2% vs. 28.9%, p = 0.04) and had clinically more severe stroke (National Institutes of Health Stroke Scale, score on admission 15.4 vs. 12.1; p = 0.0001). Significantly more patients without atrial fibrillation (61.4% vs. 43.2%, p = 0.01) had a favorable clinical outcome at three months after stroke. Nevertheless, atrial fibrillation was not an independent predictor of poor outcome at three months after stroke (p=0.66). Conclusion. Acute ischemic stroke patients, with atrial fibrillation, treated with intravenous thrombolysis, had worse outcomes than patients without atrial fibrillation did. However, it is mainly due to older age and a more severe stroke in patients with atrial fibrillation.

Tract Infections

Background and purpose On 11 March 2020, World Health Organization (WHO) declared the COVID-19 infection a pandemic. The risk of ischemic stroke may be higher in patients with COVID-19 infection similar to those with other respiratory tract infections. We present a comprehensive set of practice implications in a single document for clinicians caring for adult patients with acute ischemic stroke with confirmed or suspected COVID-19 infection. Methods The practice implications were prepared after review of data to reach the consensus among stroke experts from 18 countries. The writers used systematic literature reviews, reference to previously published stroke guidelines, personal files, and expert opinion to summarize existing evidence, indicate gaps in current knowledge, and when appropriate, formulate practice implications. All members of the writing group had opportunities to comment in writing on the practice implications and approved the final version of this document. Results This document with consensus is divided into 18 sections. A total of 41 conclusions and practice implications have been developed. The document includes practice implications for evaluation of stroke patients with caution for stroke team members to avoid COVID-19 exposure, during clinical evaluation and performance of imaging and laboratory procedures with special considerations of intravenous thrombolysis and mechanical thrombectomy in stroke patients with suspected or confirmed COVID-19 infection. Conclusions These practice implications with consensus based on the currently available evidence aim to guide clinicians caring for adult patients with acute ischemic stroke who are suspected of, or confirmed, with COVID-19 infection. Under certain circumstances, however, only limited evidence is available to support these practice implications, suggesting an urgent need for establishing procedures for the management of stroke patients with suspected or confirmed COVID-19 infection.

Recent randomized controlled clinical trials (RCTs) have revolutionized acute ischemic stroke care by extending the use of intravenous thrombolysis and endovascular reperfusion therapies in time windows that have been originally considered futile or even unsafe. Both systemic and endovascular reperfusion therapies have been shown to improve outcome in patients with wake-up strokes or symptom onset beyond 4.5 h for intravenous thrombolysis and beyond 6 h for endovascular treatment; however, they require advanced neuroimaging to select stroke patients safely. Experts have proposed simpler imaging algorithms but high-quality data on safety and efficacy are currently missing. RCTs used diverse imaging and clinical inclusion criteria for patient selection during the dawn of this novel stroke treatment paradigm. After taking into consideration the dismal prognosis of nonrecanalized ischemic stroke patients and the substantial clinical benefit of reperfusion therapies in selected late presenters, we propose rescue reperfusion therapies for acute ischemic stroke patients not fulfilling all clinical and imaging inclusion criteria as an option in a subgroup of patients with clinical and radiological profiles suggesting low risk for complications, notably hemorrhagic transformation as well as local or remote parenchymal hemorrhage. Incorporating new data to treatment algorithms may seem perplexing to stroke physicians, since treatment and imaging capabilities of each stroke center may dictate diverse treatment pathways. This narrative review will summarize current data that will assist clinicians in the selection of those late presenters that will most likely benefit from acute reperfusion therapies. Different treatment algorithms are provided according to available neuroimaging and endovascular treatment capabilities.

Cross-linking of α2-plasmin inhibitor (α2-PI) to fibrin by activated factor XIII (FXIIIa) is essential for the inhibition of fibrinolysis. Little is known about the factors modifying α2-PI incorporation into the fibrin clot and whether the extent of incorporation has clinical consequences. Herein we calculated the extent of α2-PI incorporation by measuring α2-PI antigen levels from plasma and serum obtained after clotting the plasma by thrombin and Ca2+. The modifying effect of FXIII was studied by spiking of FXIII-A-deficient plasma with purified plasma FXIII. Fibrinogen, FXIII, α2-PI incorporation, in vitro clot-lysis, soluble fibroblast activation protein and α2-PI p.Arg6Trp polymorphism were measured from samples of 57 acute ischemic stroke patients obtained before thrombolysis and of 26 healthy controls. Increasing FXIII levels even at levels above the upper limit of normal increased α2-PI incorporation into the fibrin clot. α2-PI incorporation of controls and patients with good outcomes did not differ significantly (49.4 ± 4.6% vs. 47.4 ± 6.7%, p = 1.000), however it was significantly lower in patients suffering post-lysis intracranial hemorrhage (37.3 ± 14.0%, p = 0.004). In conclusion, increased FXIII levels resulted in elevated incorporation of α2-PI into fibrin clots. In stroke patients undergoing intravenous thrombolysis treatment, α2-PI incorporation shows an association with the outcome of therapy, particularly with thrombolysis-associated intracranial hemorrhage.

Abstract Background Intravenous thrombolysis (IVT) with alteplase is the first-line therapy for acute ischemic anterior and posterior circulation strokes (ACS and PCS). Knowledge about safety and efficacy of IVT in posterior circulation stroke is deficient as most of the Egyptian studies either assessed IVT outcome in comparison to conservative therapy or its outcome in anterior circulation stroke only. Therefore, our aim was to compare the relative frequency and outcome after intravenous thrombolysis in anterior versus posterior circulation stroke patients presenting to stroke centers of Ain Shams University hospitals (ASUH). Results A total of 238 anterior circulation stroke and 61 posterior circulation strokes were enrolled, onset-to-door and door-to-needle time were statistically insignificant. NIHSS showed comparable difference at all time points despite higher scores along anterior circulation stroke; 90-day modified Rankin Scale (mRS) showed significant improvement in both groups from mRS >2 to ≤2 with a better percentage along posterior circulation stroke patients. There was insignificant difference for either incidence of death or intracranial hemorrhage (ICH) between the two groups. Conclusion IVT significantly reduced NIHSS for both anterior and posterior circulation stroke along different studied time points. Meanwhile, a higher percentage of patients with posterior circulation stroke had a better mRS outcome at 90 days.
