Outcome predictors of intravenous thrombolytic therapy in acute ischemic stroke patients: an Egyptian center experiences

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.

Intravenous Alteplase

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.

Poor Functional Outcome

Abstract Background: Recent studies have suggested that omentin-1 plays a critical role in the development of cardiovascular disease. However, reported findings are inconsistent, and no study has evaluated the association between omentin-1 levels and a poor functional outcome after ischemic stroke onset. Methods: A total of 266 acute ischemic stroke patients were included in this study. All patients were prospectively followed up for 3 months after acute ischemic stroke onset and a poor functional outcome was defined as a major disability or death occurring during the follow-up period. A multivariable logistic model was used to evaluate the association between serum omentin-1 levels and the functional outcome of ischemic stroke patients at 3 months. Results: Ischemic stroke patients with poor functional outcome had significantly lower levels of serum omentin-1 than patients without poor functional outcome at the 3-month follow-up (50.2 [40.2–59.8] vs. 58.3 [44.9–69.6] ng/mL, p<0.01). Subjects in the highest tertile of serum omentin-1 levels had a 0.38-fold risk of having poor functional outcome, compared with those in the lowest tertile (p<0.05). A negative association between omentin-1 levels and poor functional outcome was found (p for trend=0.02). The net reclassification index was significantly improved in predicting poor functional outcome when omentin-1 data was added to the multivariable logistic regression model. Conclusions: Higher omentin-1 levels at baseline were negatively associated with poor functional outcome among ischemic stroke patients. Omentin-1 may represent a biomarker for predicting poor functional outcome of acute ischemic stroke patients.

The Impact

Introduction: To date, few studies have assessed the influence of infection on neurological deterioration (ND) and other outcome measures in acute ischemic stroke. Methods: Patients admitted to our stroke center (07/08-12/10) were retrospectively assessed. Patients were excluded if they had an in-hospital stroke, unknown time of symptom onset, or delay from symptom onset to hospital arrival >48 hours. Positive blood or urine culture, or chest x-ray consistent with pneumonia were classified as infection and stratified according to whether the infection was diagnosed within the first 24 hours of admission or after 24 hours. ND was defined as an increase ≥2 points on the NIHSS score within a 24hr period. Poor functional outcome was defined as a mRS score of 3-6 on discharge. Results: Of the 334 patients included in this study, 78 had an infection (19 on admission). The majority of infections were found in the urinary tract (64%), while pneumonia (37%) and bacteremia (24%) were also common. Infection on admission was predictive of ND (Table 1; OR=2.79, 95% CI 1.18-6.64, p=0.0211) and poor functional outcome (OR=3.0, 95% CI 1.1-7.9, p=0.0182). Developing an infection during acute hospitalization was an even stronger predictor of ND (OR=11.9, 95% CI 5.8-24.5, p<0.0001) and poor functional outcome (OR=56.4, 95% CI 7.7-414, p<0.0001). After adjusting for age, NIHSS at baseline and glucose on admission, the development of an infection during acute hospitalization remained a significant predictor of ND (OR=8.9, 95% CI 4.2-18.6, p<0.0001) and poor functional outcome (OR=41.7, 95% CI 5.2-337.9, p=0.005) while an infection on admission was no longer predictive of ND (OR=1.5, 95%CI 0.59-3.99, p=0.3738) or poor functional outcome (OR=1.09, 95%CI 0.3-3.9, p=0.8984). Conclusion: Our data suggest that ischemic stroke patients who develop an infection during their acute hospitalization are at increased odds of experiencing ND and of being discharged with significant disability.

AbstractCurrently, few studies are reported on the composition of microbiota in stroke patients and the association with stroke prognosis. This study investigated the differing microbiota composition in stroke patients and confirmed the association of microbiota composition with poor functional outcome. Between January of 2018 and December of 2019, 198 patients with acute cerebral infarction were included in this study. For the case–control study, age and sex-matched normal healthy subjects (n = 200) were included when receiving their health screening examinations. We isolated bacterial extracellular membrane vesicles and extracted DNA from blood samples. Taxonomic assignments were performed by using the sequence reads of 16S rRNA genes following blood microbiota analysis. Statistical analysis was conducted appropriately by using Statistical Analysis System software. The mean age of the stroke patients were 63.7 ± 12.5 years, and the male sex was 58.5%. Of the total enrolled patients, poor functional outcome (modified Rankin Score ≥ 3) was noted in 19.7%. The principal component analysis of microbiota composition revealed significant differences between healthy control subjects and stroke patients. At the genus level, Aerococcaceae(f), ZB2(c), TM7-1(c), and Flavobacterium were significantly increased in stroke patients compared to the healthy controls, whereas Mucispirillum, rc4-4, Akkermansia, Clostridiales(o), Lactobacillus, and Stenotrophomonas were decreased considerably. For the functional outcome after ischemic stroke, Anaerococcus, Blautia, Dialister, Aerococcaceae(f), Propionibacterium, Microbacteriaceae(f), and Rothia were enriched in the group with good outcomes, whereas Ruminococcaceae(f) and Prevotella were enriched in the group with poor outcome. There was apparent dysbiosis of blood microbiota in patients with acute ischemic stroke compared to healthy people. Ruminococcaceae(f) and Prevotella were elevated in stroke patients with poor functional outcome.

Poor Functional Outcome

AbstractInsulin resistance is associated with the occurrence of stroke and atherosclerotic disease. However, the relationship between insulin resistance and the prognosis of acute ischemic stroke in non-diabetic patients is unclear. We hypothesized that insulin resistance might affect short-term functional recovery after acute ischemic stroke in non-diabetic patients. Between May 2014 and December 2016, 1377 consecutive patients with acute ischemic stroke were enrolled from a prospectively maintained stroke registry. After excluding patients with transient ischemic attacks (TIA), pre-stroke disabilities, diabetes mellitus, and patients with incomplete evaluations, 517 patients were included in the study. The homeostasis model assessment of insulin resistance (HOMA-IR) score was used to evaluate the degree of insulin resistance. The patients with the highest quartile of log HOMA-IR index scores were younger and had higher fasting blood glucose, total cholesterol, triglycerides, low-density lipoprotein, and HbA1c levels. Multivariable logistic regression analysis revealed that log HOMA-IR scores were independently associated with poor prognosis after adjusting for age and sex and p < 0.1 in univariable analysis. Insulin resistance was associated with the poor functional outcome of non-diabetic stroke patients. This evidence supports treating insulin resistance in acute ischemic stroke patients with blood glucose levels within the normal range.

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.

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 < 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 < 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 < 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.

Introduction: With an aging population, an increased number of acute stroke patients with pre-stroke dementia is expected. Although both stroke and dementia are major cause of disability, the effect of pre-stroke dementia on functional outcome after stroke has been still on debate. Hypothesis: Pre-stroke dementia is associated with poor functional outcome after acute ischemic stroke. Methods: Of 9198 stroke patients registered in the Fukuoka Stroke Registry in Japan from June 2007 to May 2014, 3843 patients with first-ever ischemic stroke within 24h of onset, who had been functionally independent before the onset, were enrolled in this study (cardioembolism [n=926], large artery atherosclerosis [n=583], small vessel occlusion [n=1045], others [n=1289]). Pre-stroke dementia was defined as any type of dementia that was present prior to the stroke. For propensity score (PS)-matched analysis, 320 pairs of patients with and without pre-stroke dementia were also selected. Study outcome was poor functional outcome (modified Rankin Scale 3-6) at discharge. Results: In the total cohort, 330 (8.6%) had pre-stroke dementia. The age (80±8 vs 69±13, year, mean±SD, p<0.01), frequencies of female (46 vs 36, %, p<0.01) and cardioembolism (41 vs 23, %, p<0.01), and NIHSS score on admission (6 [3 - 12] vs 3 [1 - 6], median [interquartile], p<0.01) were higher in patients with pre-stroke dementia than those without the dementia. Poor functional outcome (62 vs 25, %, p<0.01) were more prevalent in patients with pre-stroke dementia than those without the dementia. Multivariable-adjusted analysis showed that pre-stroke dementia was significantly associated with increased risk for poor functional outcome (OR 2.3, 95% CI 1.7-3.2). There were no interactions between pre-stroke dementia and 4 variables (age, sex, stroke subtype, and initial stroke severity [NIHSS≤7 or NIHSS≥8]). In the PS-matched analysis, pre-stroke dementia was still associated with poor functional outcome (OR 4.3, 95%CI 2.1-8.8). Conclusions: Pre-stroke dementia was significantly associated with poor functional outcome at discharge in patients with acute ischemic stroke.

New Scoring

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.
