Background and methods Intravenous thrombolysis for acute ischemic stroke in the Middle-East and North African (MENA) countries is still confined to the main urban and university hospitals. This was a prospective observational study to examine outcomes of intravenous thrombolysis-treated stroke patients in the MENA region compared to the non-MENA stroke cohort in the SITS International Registry. Results Of 32,160 patients with ischemic stroke registered using the SITS intravenous thrombolysis protocol between June 2014 and May 2016, 500 (1.6%) were recruited in MENA. Compared to non-MENA (all p < 0.001), median age in MENA was 55 versus 73 years, NIH Stroke Scale score 12 versus 9, onset-to-treatment time 138 versus 155 min and door-to-needle time 54 min versus 64 min. Hypertension was the most reported risk factor, but lower in MENA (51.7 vs. 69.7%). Diabetes was more frequent in MENA (28.5 vs. 20.8%) as well as smoking (20.8 vs. 15.9%). Hyperlipidemia was less observed in MENA (17.6 vs. 29.3%). Functional independence (mRS 0–2) at seven days or discharge was similar (53% vs. 52% in non-MENA), with mortality slightly lower in MENA (2.3% vs. 4.8%). SICH rates by SITS-MOST definition were low (<1.4%) in both groups. Conclusions Intravenous thrombolysis patients in MENA were younger, had more severe strokes and more often diabetes. Although stroke severity was higher in MENA, short-term functional independency and mortality were not worse compared to non-MENA, which could partly be explained by younger age and shorter OTT in MENA. Decreasing the burden of stroke in this young population should be prioritized.

Incidence And Mortality

Background and methods Stroke incidence and mortality are reported to have increased in the Middle-East and North African (MENA) countries during the last decade. This was a prospective observational study to examine the baseline characteristics of stroke patients in the MENA region and to compare the MENA vs. the non-MENA stroke cohort in the Safe Implementation of Treatments in Stroke (SITS) International Registry. Results Of the 13,822 patients with ischemic and hemorrhagic stroke enrolled in the SITS-All Patients Protocol between June 2014 and May 2016, 5897 patients (43%) were recruited in MENA. The median onset-to-door time was 5 h (IQR: 2:20–13:00), National Institutes of Health Stroke Scale (NIHSS) score was 8 (4–13) and age was 65 years (56–76). Hypertension (66%) and diabetes (38%) were the prevailing risk factors; large artery stenosis > 50% (25.3%) and lacunar strokes (24.1%) were the most common ischemic stroke etiologies. In comparison, non-MENA countries displayed an onset-to-door time of 5:50 h (2:00–18:45), a median of NIHSS 6 (3–14), and a median age of 66 (56–76), with other large vessel disease and cardiac embolism as the main ischemic stroke etiologies. Hemorrhagic strokes (10%) were less common compared to non-MENA countries (13.9%). In MENA, only a low proportion of patients (21%) was admitted to stroke units. Conclusions MENA patients are slightly younger, have a higher prevalence of diabetes and slightly more severe ischemic strokes, commonly of atherosclerotic or microvascular etiology. Admission into stroke units and long-term follow-up need to be improved. It is suspected that cardiac embolism and atrial fibrillation are currently underdiagnosed in MENA countries.

Safety Outcomes

Introduction: We investigated the effectiveness of intravenous thrombolysis (IVT) in acute ischemic stroke (AIS) patients with large vessel occlusion (LVO) and mild neurological deficits defined as National Institutes of Health Stroke Scale scores <6 points (mELVO). Methods: The primary efficacy outcome was three-month functional independence (FI; mRS-scores of 0-2) that was compared between patients with and without IVT treatment. Other efficacy outcomes of interest included three-month favorable functional outcome (FFO; mRS-scores of 0-1) and mRS-scores distribution at discharge and at 3 months. The safety outcomes comprised all-cause 3-month mortality, symptomatic intracranial hemorrhage (ICH), asymptomatic ICH and severe systemic bleeding. Results: We evaluated 336 AIS patients with mELVO (mean age: 63±15 years, 45% women). Patients treated with IVT (n=162) had higher FI (85.6% vs. 74.8%, p=0.027) with lower mRS scores at hospital discharge (p=0.034) compared to the rest. Three-month mRS-scores tended to be lower in the IVT group (p=0.069). No differences were detected in any of the safety outcomes including symptomatic ICH, asymptomatic ICH, severe systemic bleeding and 3-month mortality (p>0.1). IVT was associated with higher likelihood of 3-month FI (OR=2.19, 95%CI: 1.09-4.42), 3-month FFO (OR=1.99, 95%CI: 1.10-3.57) and functional improvement at discharge [cOR (per 1-point decrease in mRS-score)=2.94, 95%CI: 1.67-5.26] and at 3 months (cOR=1.72, 95%CI: 1.06-2.86) on multivariable logistic regression models adjusting for potential confounders including mechanical thrombectomy. Conclusion: IVT is independently associated with higher odds of improved discharge and three-month functional outcomes in AIS patients with mELVO. IVT does not increase the risk of systemic or intracranial bleeding.

Important Means

Advanced neuroimaging is one of the most important means that we have in the attempt to overcome time constraints and expand the use of intravenous thrombolysis (IVT). We assessed whether, and how, the prior use of advanced neuroimaging (AN), and more specifically CT/MR perfusion post-processed with RAPID software, regardless of time from symptoms onset, affected the outcomes of acute ischemic stroke (AIS) patients who received IVT. Methods. We retrospectively evaluated consecutive AIS patients who received intravenous thrombolysis monotherapy (without endovascular reperfusion) during a six-year period. The study population was divided into two groups according to the neuroimaging protocol used prior to IVT administration in AIS patients (AN+ vs. AN−). Safety outcomes included any intracranial hemorrhage (ICH) and 3-month mortality. Effectiveness outcomes included door-to-needle time, neurological status (NIHSS-score) on discharge, and functional status at three months assessed by the modified Rankin Scale (mRS). Results. The rate of IVT monotherapy increased from ten patients per year (n = 29) in the AN− to fifteen patients per year (n = 47) in the AN+ group. Although the onset-to-treatment time was longer in the AN+ cohort, the two groups did not differ in door-to-needle time, discharge NIHSS-score, symptomatic ICH, any ICH, 3-month favorable functional outcome (mRS-scores of 0–1), 3-month functional independence (mRS-scores of 0–2), distribution of 3-month mRS-scores, or 3-month mortality. Conclusion. Our pilot observational study showed that the incorporation of advanced neuroimaging in the acute stroke chain pathway in AIS patients increases the yield of IVT administration without affecting the effectiveness and safety of the treatment.

Background: Neuroprotective and neurorestorative effects have been postulated for selective serotonin-reuptake inhibitors (SSRI). We hypothesized that sertraline, which is characterized by less severe adverse effects and more stable pharmacokinetics than classic SSRI, is associated with improved functional recovery in acute ischemic stroke patients with motor deficits.Methods: Prospective observational study of consecutive acute ischemic stroke patients who received sertraline for clinically suspected post-stroke depression (PSD) or at high risk for PSD. Eligibility comprised acute motor deficit caused by ischemic stroke (≥2 points on NIHSS motor items) and functional independence pre-stroke (mRS ≤1). Decision to initiate treatment with SSRI during hospital stay was at the discretion of the treating stroke physician. Patients not receiving sertraline served as control group. Favorable functional recovery defined as mRS ≤2 was prospectively assessed at 3 months. Multivariable logistic regression analysis was used to explore the effects of sertraline on 3-months functional recovery. Secondary outcomes were frequency of any and incident PSD (defined by BDI ≥10) at 3 months.Results: During the study period (03/2017–12/2018), 114 patients were assigned to sertraline (n = 72, 62.6%) or control group (n = 42, 37.4%). At study entry, patients in sertraline group were more severely neurologically affected than patients in the control group (NIHSS: 8 [IQR, 5–11] vs. 5 [IQR, 4–7]; p = 0.002). Also, motor NIHSS scores were more pronounced in sertraline than in control group (4 [IQR 2–7] vs. 2 [IQR 2–4], p = 0.001). After adjusting for age and baseline NIHSS, multivariable regression analysis revealed a significant association between sertraline intake and favorable functional outcome at 3 months (OR 3.10, 95% CI 1.02–9.41; p = 0.045). There was no difference between both groups regarding the frequency of any depression at 3 months (26/53 [49.1%] vs. 14/28 [50.0%] patients, p = 0.643, BDI ≥10). However, fewer incident depressions were observed in sertraline group patients compared to patients in control group (0/53 [0%] vs. 5/28 [17.9%] patients, p = 0.004).Conclusions: In this non-randomized comparison, early treatment with sertraline tended to favor functional recovery in patients with acute ischemic stroke. While exploratory in nature, this hypothesis needs further investigation in a clinical trial.

Background & Purpose: In a recent randomized controlled trial (RCT) of intravenous thrombolysis (IVT) in acute ischemic stroke (AIS) antiplatelet pre-treatment (APP) was associated with adverse outcomes. We conducted a systematic review and meta-analysis of available RCTs to investigate the association of APP with outcomes of AIS patients treated with IVT. Methods: The outcome events of interest included symptomatic intracranial hemorrhage (sICH), complete recanalization (CR), 3-month favorable functional outcome (FFO, mRS-score: 0-1), functional independence (FI, mRS-score: 0-2), and mortality. Both unadjusted and adjusted (for baseline stroke severity and age) analyses were performed using random effects methodology. Results: We included 8 RCTs (5,332 total patients, 34% with APP). In unadjusted analyses (Figure 1), APP was associated with higher likelihood of sICH (OR=2.01, 95%CI: 1.53-2.63) and death (OR=1.59, 95%CI: 1.24-2.03; 1C) and lower likelihood of 3-month FI (OR=0.69, 0.56-0.85). No association was detected between APP and 3-month FFO (OR=0.79, 95%CI: 0.58-1.07) and CR (OR=0.64, 95%CI: 0.04-11.66). In adjusted analyses (Figure 2), APP was related to higher odds of sICH (OR=1.89, 95%CI: 1.14-3.12). There was no association between APP and 3-month FI (OR=0.94, 95%CI: 0.70-1.26) or death (OR=1.01, 95%CI: 0.55-1.86). In all analyses no evidence of heterogeneity was detected. Conclusion: Despite APP association with a higher risk of sICH after thrombolysis, three-month functional outcomes appear un-affected by APP. APP before IVT should not be used as an excuse to withhold or to lower the dose of IVT.

Background: Stroke is an important health problem causing of morbidity and mortality globally. Serum ferritin has gained clinical significance as a prognostic factor that can aggravate the cytotoxicity of brain ischemia. The present study investigated the prognostic significance of serum ferritin levels with the severity of stroke using NIHSS scale.Methods: It was a prospective observational study conducted on 60 patients with acute ischemic stroke admitted in the general medicine department of a tertiary care teaching hospital. Serum ferritin levels were assessed on all participants using the instrument “immulite”. National institute of health stroke scale scoring was applied at the time of admission and on the seventh day to assess the impairment caused by a stroke. IBM SPSS version 22 was used for statistical analysis.Results: The mean serum ferritin levels at admission in patients with severe stroke, moderate stroke and mild and less stroke were 337.41±58.76, 285.56±49.37, and 197.91±111.01 ng/mL, respectively. The mean serum ferritin levels at admission were 178.76±114.70 ng/mL and 341.91±62.292 ng/mL in subjects who did not deteriorate and those who deteriorated, respectively. Whereas the mean serum ferritin levels on the sixth day were 198.34±106.88 and 348.10±57.34 ng/mL in subjects who did not deteriorate and those who deteriorated, respectively.Conclusions: Serum ferritin has a significant positive correlation with the severity of acute ischemic stroke severity on admission (p<0.001) and negative correlation with the severity of acute ischemic stroke severity on seventh day of admission (p<0.001). Thus, serum ferritin can be used as a prognostic marker in acute ischemic stroke.

Poor Outcomes

Objective:: Increased leukocyte count are positively associated with poor outcomes and all-cause mortality in coronary heart disease, cancer, and ischemic stroke. The role of leukocyte count in acute ischemic stroke (AIS) remains important. We aimed to investigate the association between admission leukocyte count before thrombolysis with recombinant tissue plasminogen activator (rt-PA) and 3-month outcomes in AIS patients. Methods:: This retrospective study included consecutive AIS patients who received intravenous (IV) rt-PA within 4.5 h of symptom onset between January 2016 and December 2018. We assessed outcomes including short-term hemorrhagic transformation (HT), 3-month mortality, and functional independence (modified Rankin Scale [mRS] score of 0–2 or 0–1). Results:: Among 579 patients who received IV rt-PA, 77 (13.3%) exhibited HT at 24 h, 43 (7.4%) died within 3 months, and 211 (36.4%) exhibited functional independence (mRS score: 0–2). Multivariable logistic regression revealed admission leukocyte count as an independent predictor of good and excellent outcomes at 3 months. Each 1-point increase in admission leukocyte count increased the odds of poor outcomes at 3 months by 7.6% (mRS score: 3–6, odds ratio (OR): 1.076, 95% confidence interval (CI): 1.003–1.154, p=0.041) and 7.8% (mRS score: 2–6, OR: 1.078, 95% CI: 1.006–1.154, p=0.033). Multivariable regression analysis revealed no association between HT and 3-month mortality. Admission neutrophil and lymphocyte count were not associated with 3-month functional outcomes or 3-month mortality. Conclusion:: Lower admission leukocyte count independently predicts good and excellent outcomes at 3 months in AIS patients undergoing rt-PA treatment.

The Impact

The objective of this study is to assess the impact of recanalization (spontaneous and therapeutic) on upper limb functioning and general patient functioning after stroke. This is a prospective, observational study of patients hospitalized due to acute ischemic stroke in the territory of the middle cerebral artery (n = 98). Patients completed a comprehensive rehabilitation program and were followed-up for 24 weeks. The impact of recanalization on patient functioning was evaluated using the modified Rankin Scale (mRS) and Stroke Upper Limb Capacity Scale (SULCS). General and upper limb functioning improved markedly in the first three weeks after stroke. Age, gender, and National Institutes of Health Stroke Scale (NIHSS) score at admission were associated with general and upper limb functioning at 12 weeks. Successful recanalization was associated with better functioning. Among patients who underwent therapeutic recanalization, NIHSS scores ≥16.5 indicate lower general functioning at 12 weeks (sensibility = 72.4%; specificity = 78.6%) and NIHSS scores ≥13.5 indicate no hand functioning at 12 weeks (sensibility = 83.8%; specificity = 76.5%). Recanalization, either spontaneous or therapeutic, has a positive impact on patient functioning after acute ischemic stroke. Functional recovery occurs mostly within the first 12 weeks after stroke, with greater functional gains among patients with successful recanalization. Higher NIHSS scores at admission are associated with worse functional recovery.

AbstractTo date, very few studies focused their attention on efficacy and safety of recanalisation therapy in acute ischemic stroke (AIS) patients with cancer, reporting conflicting results. We retrospectively analysed data from our database of consecutive patients admitted to the Udine University Hospital with AIS that were treated with recanalisation therapy, i.e. intravenous thrombolysis (IVT), mechanical thrombectomy (MT), and bridging therapy, from January 2015 to December 2019. We compared 3-month dependency, 3-month mortality, and symptomatic intracranial haemorrhage (SICH) occurrence of patients with active cancer (AC) and remote cancer (RC) with that of patients without cancer (WC) undergoing recanalisation therapy for AIS. Patients were followed up for 3 months. Among the 613 AIS patients included in the study, 79 patients (12.9%) had either AC (n = 46; 7.5%) or RC (n = 33; 5.4%). Although AC patients, when treated with IVT, had a significantly increased risk of 3-month mortality [odds ratio (OR) 6.97, 95% confidence interval (CI) 2.42–20.07, p = 0.001] than WC patients, stroke-related deaths did not differ between AC and WC patients (30% vs. 28.8%, p = 0.939). There were no significant differences between AC and WC patients, when treated with MT ± IVT, regarding 3-month dependency, 3-month mortality and SICH. Functional independence, mortality, and SICH were similar between RC and WC patients. In conclusion, recanalisation therapy might be used in AIS patients with nonmetastatic AC and with RC. Further studies are needed to explore the outcome of AIS patients with metastatic cancer undergoing recanalisation therapy.
