Background. This study seeks to assess interleukin-37 (IL-37) serum level in acute ischemic stroke and the value of predicting 3-month stroke recurrence and functional outcome in acute ischemic stroke. Methods. From January 1, 2018, to June 30, 2019, all consecutive first-ever acute ischemic stroke patients from our hospital, China, were included. Serum samples, clinical information, and stroke severity (defined by the National Institute of Health stroke scale (NIHSS) score) were collected at baseline. Serum IL-37 level was measured by the enzyme-linked immunosorbent assay (ELISA) method. Functional impairment (defined by the modified Rankin scale (mRS)) and recurrent stroke were assessed 3 months after admission. The relation of IL-37 with either clinical severity at baseline, unfavorable functional outcome, or stroke recurrence at follow-up was evaluated by logistic regression analysis, and the results were presented as odds ratios (OR) with 95% confidence intervals (CI). Results. Three hundred and ten stroke patients were included. The median IL-37 serum level in those patients was 344.1 pg/ml (interquartile range (IQR), 284.4-405.3 vs. control cases: 122.3 pg/ml (IQR, 104.4-1444.0); P < 0.001 ). At 3 months, a total of 36 (11.6%) patients had a stroke recurrence. IL-37 serum levels in those patients were higher than in those patients without stroke recurrence (417.0 pg/ml (IQR, 359.3-436.1) vs. 333.3 pg/ml (279.0-391.0)). In a logistic model adjusted for other factors, IL-37 in the highest quartile (>405.3 pg/ml) was still associated with recurrent stroke ( OR = 3.32 ; 95 % CI = 2.03 – 6.13 ; P < 0.001 ). IL-37 could promote the NIHSS score (area under the curve (AUC) of the IL-37/NIHSS, 0.75; 95% CI, 0.67–0.83; P < 0.001 ), corresponding to a difference of 0.085 (0.005). Serum IL-37 increases in patients with poor outcome, and an IL-37 in the highest quartile is related to poor outcome ( OR = 4.85 ; 95 % CI = 3.11 − 8.22 ; P < 0.001 ). Conclusion. Serum IL-37 increased in patients after ischemic stroke and was associated with stroke recurrence events and poor stroke outcomes. Large randomized controlled trials should be carried out to confirm whether IL-37 lowering treatment improves stroke prognosis.

Background: This study assessed the incidence and predictors of short-term stroke recurrence in ischemic stroke patients with active cancer, and elucidated whether cancer-associated hypercoagulation is related to early recurrent stroke. Methods: We retrospectively enrolled acute ischemic stroke patients with active cancer admitted to our hospital between 2006 and 2017. Active cancer was defined as diagnosis or treatment for any cancer within 12 months before stroke onset, known recurrent cancer or metastatic disease. The primary clinical outcome was recurrent ischemic stroke within 30 days. Results: One hundred ten acute ischemic stroke patients with active cancer (73 men, age 71.3 ± 10.1 years) were enrolled. Of those, recurrent stroke occurred in 12 patients (11%). When patients with and without recurrent stroke were compared, it was found that those with recurrent stroke had a higher incidence of pancreatic cancer (33 vs. 10%), systemic metastasis (75 vs. 39%), multiple vascular territory infarctions (MVTI; 83 vs. 40%), and higher ­D-dimer levels (16.9 vs. 2.9 µg/mL). Multivariable logistic regression analysis showed that each factor mentioned above was not significantly associated with stroke recurrence independently, but high D-dimer (hDD) levels (≥10.4 µg/mL) and MVTI together were significantly associated with stroke recurrence (OR 6.20, 95% CI 1.42–30.7, p = 0.015). Conclusions: Ischemic stroke patients with active cancer faced a high risk of early recurrent stroke. The concurrence of hDD levels (≥10.4 µg/mL) and MVTI was an independent predictor of early recurrent stroke in active cancer patients. Our findings suggest that cancer-associated hypercoagulation increases the early recurrent stroke risk.

Background: Thrombolysis is often withheld from acute ischemic stroke patients presenting with mild symptoms; however, up to 40% of these patients end up with a poor outcome when left untreated. Since there is lack of consensus on the definition of minor symptoms, we aimed at addressing this issue by looking for features that would better predict functional outcomes at 3 months. Methods: Among all acute ischemic stroke patients admitted to our Stroke Unit (n = 1,229), we selected a cohort of patients who arrived within 24 hours from symptoms onset, with baseline NIHSS ≤6, not treated with thrombolysis (n = 304). Epidemiological data, comorbidities, radiological features and clinical presentation (NIHSS items) were collected to identify predictors of outcome. Our cohort was tested against minor stroke definitions selected from the literature and a newly proposed one. Results: Three months after stroke onset, 97 patients (31.9%) had mRS ≥2. Independent predictors of poor outcome were age (OR 0.97 [95% CI 0.95-9.99]) and baseline NIHSS score (OR 0.79 [95% CI 0.67-0.94]), while cardioembolic aetiology was negatively associated (OR 3.29 [95% CI 1.51-7.14]). Items of NIHSS associated with poor outcome were impairment of right motor arm (OR 0.49 [95% CI 0.27-0.91]) or the involvement of any of the motor items (OR 0.69 [95% CI 0.48-0.99]). The definition of minor stroke as NIHSS ≤3 and the new proposed definition had the highest sensitivity and accuracy and were independent predictors of outcome. Conclusions: Our study confirmed that in spite of a low NIHSS score, one third of patients had poor outcome. As already described, age and NIHSS score remained independent predictors of poor outcome even in mild stroke. Also, motor impairment appeared a major determinant of poor outcome. The new proposed definition of minor stroke featured the NIHSS score and the NIHSS items that better predicted functional outcome. Awareness that even minor stroke can yield to poor outcome should sensitize patients to arrive early to the ED and neurologists to administer rt-PA.

Toe Brachial Index

Introduction: We investigated whether the toe–brachial index (TBI) is associated with stroke prognosis and evaluated this association in patients with normal ankle–brachial index (ABI).Methods: Acute ischemic stroke patients who underwent TBI measurements were enrolled. Poor functional outcome was defined as modified Rankin Scale score ≥3. Major adverse cardiovascular event (MACE) was defined as stroke recurrence, myocardial infarction, or death. Normal ABI was defined as 0.9 ≤ ABI ≤ 1.4.Results: A total of 1,697 patients were enrolled and followed up for a median 39.7 (interquartile range, 25.7–54.6) months. During the period, 305 patients suffered MACE (18.0%), including 171 (10.1%) stroke recurrences. TBI was associated with hypertension, diabetes, atrial fibrillation, aortic plaque score, ABI, and brachial–ankle pulse wave velocity (all p &lt; 0.05). In multivariable logistic regression, TBI was inversely associated with poor functional outcome in all patients [odds ratio (OR) 0.294, 95% confidence interval (CI) 0.114–0.759], even in patients with normal ABI (OR 0.293, 95% CI 0.095–0.906). In multivariable Cox regression, TBI &lt; 0.6 was associated with stroke recurrence [hazard ratio (HR) 1.651, 95% CI 1.135–2.400], all-cause mortality (HR 2.105, 95% CI 1.343–3.298), and MACE (HR 1.838, 95% CI 1.396–2.419) in all patients. TBI &lt; 0.6 was also associated with stroke recurrence (HR 1.681, 95% CI 1.080–2.618), all-cause mortality (HR 2.075, 95% CI 1.180–3.651), and MACE (HR 1.619, 95% CI 1.149–2.281) in patients with normal ABI.Conclusions: Low TBI is independently associated with poor short- and long-term outcomes in acute ischemic stroke patients despite normal ABI.

Objective: This study evaluated the efficacy of thrombolysis with 0.6 mg/kg intravenous alteplase for acute ischemic stroke patients within 6 h of stroke onset. Methods: This cross-sectional study collected data of patients with ischemic stroke received intravenous thrombolytic therapy with 0.6 mg/kg alteplase within 6 h of onset in Cipto Mangunkusumo General Hospital (Rumah Sakit Cipto Mangunkusumo [RSCM]) between November 2014 and August 2017. Efficacy of the thrombolytic therapy was evaluated using the National Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS). NIHSS evaluated on 24 h and 7 d post thrombolytic therapy portrayed clinical outcomes of patients while mRS evaluated on day 30 post-thrombolysis portrayed the functional outcome of patients. Results: The median NIHSS score decreased on 24 h and 7 d post-thrombolysis. 33.3% patients experienced a reduction of NIHSS score ≥4 on 24 h post thrombolytic therapy. On day 7 following thrombolysis, 57.4% patients had a good clinical outcome. On day 30 follow-up, 55.6% patients had a good functional outcome. Conclusion: Thrombolysis using 0.6 mg/kg intravenous alteplase within 6 h of onset is effective for acute ischemic stroke patients.

ABSTRACT Introduction: Thrombolytic therapy in acute ischemic stroke has been approved for treatment of acute stroke for past two decades. However, identification of predictors of poor outcome after the intravenous (IV) alteplase therapy in acute stroke patients is a matter of research. The present study was conducted with the aim of identifying poor prognostic factors in patients of acute ischemic stroke patients. Methods: The data of 31 acute stroke patients treated with alteplase were gathered to identify the factors that were independent predictors of the poor outcome. Outcome was dichotomized using modified Rankin scale (mRS) score and National Institutes of Health Stroke Scale (NIHSS) score at 3 months after treatment into good outcome mRS - 0–2 and poor outcome mRS - 3–6. Predictors of poor outcome were analyzed. Results: Good outcome (mRS – score 0–2) was seen in 15 (48.4%) patients with median age of (60) and poor outcome (mRS – score 3–6) was seen in 16 (51.6%) patients median age of 75 years, which was statistically significant with the P = 0.002. The presence of risk factors such as hypertension, diabetes, dyslipidemia, smoking, alcohol intake, history of stroke, coronary artery disease, and rheumatic heart disease among the two groups did not seem influence outcome. The severity of stroke as assessed by NIHSS score at the time of presentation was significantly higher among the patients with poor outcome, with P = 0.01. Conclusion: Advance age and higher NIHSS score at the time of onset of stroke and are the independent predictors of the poor outcome after thrombolysis with IV alteplase treatment in acute ischemic stroke patients.

Introduction: As indicators of the systemic inflammatory response, the neutrophil-to-lymphocyte ratio (NLR) have been proposed to predict the clinical outcome in cardiovascular disease, diabetes, and various malignancies. We assessed the significance of NLR as a predictor of the outcome in patients with acute ischemic stroke. Methods: We retrospectively analyzed the clinical characteristics, laboratory parameters, and NLR in 356 consecutive patients (62.2% men, mean age 65.8±13.0 years) within 3 days after the onset of acute ischemic stroke between July 2012 and March 2015. The NLR was calculated from the differential counts by dividing the neutrophil number by the lymphocyte number at the time of admission. All subjects were divided into four groups according to quartiles of the NLR. Outcomes were measured as 3-month modified Rankin scale (mRS) score. A good functional outcome was defined as a mRS of 0-2 points, whereas a poor outcome was defined as a mRS of >2 points. Multivariate logistic regression analysis was used to assess association among the clinical, inflammatory and serological parameters including NLR and mRS scores. Results: The frequency of atrial fibrillation, heart failure, hypertension, and diabetes, the NIHSS score at admission, and the level of hs-CRP, D-dimer and the NLR were each significantly higher in the poor outcome group (p < 0.05). The cut-off values of NLR and NIHSS score at admission for prediction of the poor outcome were 2.135 (sensitivity 0.864 and specificity 0.533) and 3.5 (sensitivity 0.862 and specificity 0.787), respectively. In age-adjusted analysis, the NLR were significantly correlated with 3-month mRS score (partial r = 0.329, p < 0.001) and NIHSS score at discharge (partial r = 0.301, p < 0.001). Multivariate logistic regression analysis demonstrated that age of ≥65 (OR, 10.2; 95% CI, 3.31-31.21, p < 0.001), presence of diabetes mellitus (OR, 3.3; 95% CI, 1.36-8.12, p = 0.008), NIHSS score of ≥4 (OR, 26.4 95% CI, 9.81-71.15, p < 0.001), NLR of ≥2.135 (OR, 9.2; 95% CI, 3.18-26.4, p < 0.001) were independently associated with poor functional outcome. Conclusion: The NLR is a useful marker for short-term functional outcome in acute ischemic stroke. The NLR may have a role in risk stratification for predicting poor outcome.

Background: The Houston IAT (HIAT) score predicts poor outcome following endovascular stroke therapy based on clinical variables (age, serum glucose, and NIHSS score). We aimed to validate the HIAT score in an independent cohort of patients treated with endovascular therapy (DEFUSE 2) and determine if prediction of poor outcome could be improved by including neuroimaging variables in the prediction score. Methods: Patients enrolled in the DEFUSE 2 study had a clinical diagnosis of acute ischemic stroke and underwent MRI prior to endovascular treatment. Poor functional outcome was defined as a modified Rankin Scale score of 4 to 6 at day 90. The relationship between baseline clinical and neuroimaging variables and poor functional outcome was assessed using univariate and multivariate logistic regression. Statistically significant variables in the multivariate model were used to create a new scoring system. We evaluated the new scoring system and the HIAT score using ROC analysis. Results: One hundred and ten patients were included in the analysis; forty-two patients had a poor functional outcome. Validation of the HIAT score demonstrated similar ROC properties in the DEFUSE 2 cohort (AUC=0.69) compared to the Houston derivation cohort (AUC=0.73). In DEFUSE 2, age (p=0.001), baseline DWI volume (p=0.09), baseline NIHSS score (p=0.03) and hypertension (p=0.003) were associated with poor functional outcome in univariate analysis. In multivariate analysis, age (p<0.001) and baseline DWI volume (p=0.03) were independent predictors of poor functional outcome. Based on this we developed a new scoring system with a maximum of 3 points awarded for age (0 points, < 55; 1 point, 56-69; 2 points, 70-79; 3 points, ≥ 80) and a maximum of 1 point awarded for baseline DWI volume (0 points, volume ≤ 15 cc; 1 point, volume >15 cc). The percentage of patients with poor functional outcomes increased with the number of points awarded (0% poor outcomes in patients with 0 points, 25% with 1 point, 30% with 2 points, 75% with 3 points, and 89% with 4 points). The AUC for the new scoring system was 0.82. Conclusion: The new scoring system that incorporates baseline DWI volume and age predicts poor outcome more accurately than a scoring system based on clinical variables alone.

Abstract Background The relationship between aminotransferases and cardiovascular outcomes has been inconsistent in previous studies. We aimed to investigate the association of aminotransferases with clinical outcomes after acute ischemic stroke (AIS) or transient ischemic attack (TIA). Methods 17,178 AIS or TIA patients with serum alanine aminotransferase (ALT) levels < 120 U/L were included from the China National Stroke Registry (CNSR) for current analysis. Composite endpoint is comprised of recurrent stroke and all-cause mortality. Poor functional outcome is defined as modified Rankin scale of 3-6. Multivariable logistic regression was used to evaluate the risks of one-year all-cause mortality, recurrent stroke, composite endpoint and poor functional outcome according to increasing sex-specific quintiles of ALT/ aspartate aminotransferase (AST) respectively. Results One-year incidences of all-cause mortality, recurrent stroke, composite endpoint and poor functional outcome were 11.9%, 6.0%, 13.7% and 28.2% respectively in patients with the lowest quintile of ALT, and 7.4%, 3.6%, 9.0% and 17.9% respectively in the highest quintile. Compared with the lowest ALT quintile, the adjusted odds ratios with 95% confidence interval of the highest quintile were 0.55 (0.43-0.70) for all-cause mortality, 0.61 (0.45-0.83) for stroke recurrence, 0.62 (0.49-0.77) for composite endpoint, and 0.67 (0.56-0.80) for poor functional outcome. There was no significant interaction of ALT with age, sex, diabetes, dyslipidemia and alcohol consumption for all outcomes (p for interaction ≥ 0.10). Conclusions Low serum ALT may serve as an independent predictor for all-cause mortality, stroke recurrence, composite endpoint and poor functional outcome after stroke.

Abstract Background Intravenous thrombolytic therapy remains the guideline-recommended treatment to improve outcomes after acute ischemic stroke. However, the functional outcome among patients with acute ischemic stroke after receiving intravenous thrombolytic therapy is influenced by huge variety of factors, and this was the aim of our study to evaluate the outcome predictors of intravenous thrombolytic therapy in a sample of Egyptian patients with acute ischemic stroke. Methods We enrolled 183 acute ischemic stroke patients who were treated with intravenous recombinant tissue plasminogen activator (IV rtPA) according to the last updated guidelines of American Heart Association and American Stroke Association (AHA/ASA) from February 2018 to February 2020; however, only 150 patients of them completed our study plan till the end. Data of study variables were collected, analyzed statistically and correlated with the functional outcome 3 months after receiving IV rtPA using the modified Rankin Scale (mRS). Results Good functional outcome was seen in 98 (65.3%) patients and poor functional outcome was seen in 52 (34.7%) patients. Multivariate analysis of the study variables was done to detect the significant independent predictors of the functional outcome. Atrial fibrillation (AF) (P value < 0.001*OR 6.28* (95% C.I)), hypertension (P value 0.001*OR 3.65*(95% C.I)), diabetes mellitus (DM) (P value 0.009*OR 2.805*(95% C.I)), increased National Institute of Health Stroke Scale (NIHSS) score 24 h after receiving IV rtPA (P value 0.003* OR 8.039* (95% C.I)), increased pulsatility index (PI) value in cerebral vessels at the same side of stroke lesion (P value 0.038* OR 42.48*(95% C.I)) were the significant independent predictors of poor functional outcome. On the other hand decreased NIHSS score 24 h after receiving IV rtPA (P value 0.003* OR 0.124*(95% C.I)), Normal value of PI in cerebral vessels at the same side of stroke lesion (P value 0.038* OR 42.48*(95% C.I)) were the significant independent predictors of good functional outcome. Conclusion Intravenous thrombolytic therapy improves the functional outcome of acute ischemic stroke patients. Also, AF, hypertension, DM, NIHSS 24 h after receiving IV rtPA and PI could be used as independent predictors of the functional outcome.

OBJECTIVEWhile the benefit of mechanical thrombectomy (MT) for patients with anterior circulation acute ischemic stroke with large-vessel occlusion (AIS-LVO) has been clearly established, difficult vascular access may make the intervention impossible or unduly prolonged. In this study, the authors evaluated safety as well as radiographic and functional outcomes in stroke patients treated with MT via direct carotid puncture (DCP) for prohibitive vascular access.METHODSThe authors retrospectively studied patients from their prospective AIS-LVO database who underwent attempted MT between 2015 and 2018. Patients with prohibitive vascular access were divided into two groups: 1) aborted MT (abMT) after failed transfemoral access and 2) attempted MT via DCP. Functional outcome was assessed using the modified Rankin Scale at 3 months. Associations with outcome were analyzed using ordinal logistic regression.RESULTSOf 352 consecutive patients with anterior circulation AIS-LVO who underwent attempted MT, 37 patients (10.5%) were deemed to have prohibitive vascular access (mean age [± SD] 82 ± 11 years, mean National Institutes of Health Stroke Scale [NIHSS] score 17 ± 5, with females accounting for 75% of the patients). There were 20 patients in the DCP group and 17 in the abMT group. The two groups were well matched for the known predictors of clinical outcome: age, sex, and admission NIHSS score. Direct carotid access was successfully obtained in 19 of 20 patients. Successful reperfusion (thrombolysis in cerebral infarction score 2b or 3) was achieved in 16 (84%) of 19 patients in the DCP group. Carotid access complications included an inability to catheterize the carotid artery in 1 patient, neck hematomas in 4 patients, non–flow-limiting common carotid artery (CCA) dissections in 2 patients, and a delayed, fatal carotid blowout in 1 patient. The neck hematomas and non–flow-limiting CCA dissections did not require any subsequent interventions and remained clinically silent. Compared with the abMT group, patients in the DCP group had smaller infarct volumes (11 vs 48 ml, p = 0.04), a greater reduction in NIHSS score (−4 vs +2.9, p = 0.03), and better functional outcome (shift analysis for 3-month modified Rankin Scale score: adjusted OR 5.2, 95% CI 1.02–24.5; p = 0.048).CONCLUSIONSDCP for emergency MT in patients with anterior circulation AIS-LVO and prohibitive vascular access is safe and effective and is associated with higher recanalization rates, smaller infarct volumes, and improved functional outcome compared with patients with abMT after failed transfemoral access. DCP should be considered in this patient population.
