Background: Neutrophil to lymphocyte ratio is an easily evaluated systemic inflammation indicator. However, there are limited reports on neutrophil to lymphocyte ratio and functional outcome in ischemic stroke. In this study, we aimed to evaluate the association of neutrophil to lymphocyte ratio and stroke severity, short term functional outcomes and mortality in patients with acute ischemic stroke. Methods: The clinical data of patients who were > 18 age-old and hospitalized with acute ischemic stroke in Baskent University Hospital, Ankara, Turkey between January 2018 and May 2019 were studied retrospectively. Neutrophil to lymphocyte ratio were measured. The neutrophil to lymphocyte ratio and National Institute of Health Stroke Scale (NIHSS) score at admission, mortality during hospitalization and Modified Rankin Scale (mRS) score at discharge of the patients with acute ischemic stroke were correlated. Results: Among the acute ischemic stroke patients due to the exclusion criteria, the data of 134 patients were evaluated. Median age of the patients were 76± 12.5 years and 82 patients (61.2%) were male. The median NIHSS scores of the patients at admission was 5±4.5. Mortality during the hospitalization was seen in 8 patients (6%). The median neutrophil to lymphocyte ratio value of the patients at admission were found to be 2.6±3.4. Neutrophil to lymphocyte ratio and NIHSS scores of the patients at admission, duration of the hospitalization, mRS scores at discharge and mortality during hospitalization were found to be positively correlated. Conclusion: Neutrophil to lymphocyte ratio is a simple and easily measured marker and can be used as a potential indicator for prognosis in acute ischemic stroke. However further prospective multicenter investigations are required to confirm the role of neutrophil to lymphocyte ratio for predicting the prognosis in acute ischemic stroke patients.

Background: Neutrophil-to-lymphocyte ratio (NLR) is an indicator of poor prognosis in acute ischemic stroke (AIS), but associations between NLR with stroke severity and prognosis of intracranial atherosclerotic stenosis (ICAS)-related ischemic events have not been well-elucidated; therefore, we aimed to evaluate whether admission NLR levels correlate with the early stroke severity and short-term functional prognosis in patients with symptomatic intracranial atherosclerotic stenosis (sICAS).Methods: This retrospective study enrolled 899 consecutive patients with AIS attributed to ICAS at Xiangya Hospital stroke center between May 2016 and September 2020. The initial stroke severity was rated by the admission National Institutes of Health Stroke Scale (NIHSS) scores, and the short-term prognosis was evaluated using the 14-day modified Rankin Scale (mRS) scores after stroke onset. A severe stroke was defined as NIHSS >8; an unfavorable functional outcome was defined as mRS scores of 3–6. Admission NLR was determined based on circulating neutrophil and lymphocyte counts.Results: The median admission NLR of all patients was 2.80 [interquartile range (IQR), 2.00–4.00]. In univariate analysis, admission NLR was significantly elevated in patients with severe stroke and poor short-term prognosis. After multivariate adjustment, admission NLR levels were significantly correlated with severe stroke [odds ratio (OR), 1.132; 95% confidence interval (95% CI), 1.038–1.234; P = 0.005] and unfavorable short-term prognosis (OR, 1.102; 95% CI, 1.017–1.195; P = 0.018) in Model 1. In Model 2, the highest NLR tertile (≥3.533) remained an independent predictor of severe stroke (OR, 2.736; 95% CI, 1.590–4.708; P < 0.001) and unfavorable functional outcome (OR, 2.165; 95% CI, 1.416–3.311; P < 0.001) compared with the lowest NLR tertile (<2.231). The receiver operating characteristic (ROC) curves showed the predictability of NLR regarding the stroke severity [area under the curve (AUC), 0.659; 95% CI, 0.615–0.703; P < 0.001] and short-term prognosis (AUC, 0.613; 95% CI, 0.575–0.650; P < 0.001). The nomograms were constructed to create the predictive models of the severity and short-term outcome of sICAS.Conclusions: Elevated admission NLR levels were independently associated with the initial stroke severity and could be an early predictor of severity and poor short-term prognosis in AIS patients with ICAS, which might help us identify a target group timely for preventive therapies.

Abstract Background Several factors affect acute ischemic stroke (AIS) outcomes. Objective This study aimed to assess the role of the leukocyte count, neutrophil/lymphocyte ratio (NLR), and c reactive protein (CRP) as early predictors of outcome in AIS patients. Methods This study was conducted on 60 AIS patients. They were subjected to detailed history taking, clinical examination, brain imaging, and laboratory assessment including the CRP, white blood cell (WBC) count, absolute neutrophil count (ANC), absolute lymphocyte count (ALC), and NLR which is calculated by dividing ANC by ALC. Neurological scales were used to assess the level of consciousness by the Glasgow Coma Scale (GCS) and stroke severity by the National Institute of Health Stroke Scale (NIHSS) at the first 48 h of stroke onset as well as 1 week and 2 weeks later for the assessment of short-term functional neurological outcome. Results Sixty percent of the patients had unfavorable outcomes assessed by the Modified Rankin Scale (mRS). Patients with unfavorable outcomes had higher NIHSS scores. NLR was positively correlated with WBC count, ANC, and CRP. The higher WBC, NLR, and NIHSS, the unfavorable the outcome was. Conclusion The higher WBC, the NLR, and the level of CRP at the onset of AIS, the more severe stroke and the poorer the short-term outcome are expected.

The coronavirus disease 2019 (COVID-19) pandemic has caused millions of deaths worldwide. Acute ischemic stroke is a life-threatening risk factor for COVID-19 infection. Neutrophil-to-lymphocyte ratio (NLR) is one of the predictors of poor prognosis in acute ischemic stroke. The aim of this study was to assess the correlation between NLR values and the clinical outcome of acute thrombotic stroke patients with COVID-19 that was measured using the National Institutes of Health Stroke Scale (NIHSS). A cross-sectional hospital-based study was conducted in Dr. Soetomo General Hospital Surabaya, Indonesia. Patients with acute thrombotic stroke and COVID-19 admitted between 1 March 2020 and 31 May 2021 were recruited. The NLR values and the NIHSS scores were assessed during the admission and the correlation between NLR and NIHSS scores was calculated. This study included 21 patients with acute thrombotic stroke and COVID-19, consisting of 12 males and 9 females. The mean age was 57.6 years old. The mean NLR values was 8.33±6.7 and the NIHSS scores ranging from 1 to 33. Our data suggested a positive correlation between NLR values and NIHSS scores, r=0.45 with p=0.041. In conclusion, the NLR value is potentially to be used as a predictor of the clinical outcome in acute thrombotic stroke patients with COVID-19. However, further study is warranted to validate this finding.

Abstract Background The role of oxidative stress in neuronal injury due to ischemic stroke has been an interesting topic in stroke research. Malondialdehyde (MDA) has emerged as a sensitive oxidative stress biomarker owing to its ability to react with the lipid membranes. Total antioxidant power (TAP) is another biomarker to estimate the total oxidative stress in stroke patients. We aimed to determine the oxidative stress in acute stroke patients by measuring MDA and TAP. Materials and Methods MDA and TAP were determined in 100 patients with ischemic stroke and compared with that in 100 age- and sex-matched healthy adults. Demographic data, stroke severity measured by the National Institutes of Health Stroke Scale (NIHSS), and disability measured by the Barthel index (BI) were recorded. The association of MDA and TAP with other variables was analyzed by paired t-test. Results Of the whole sample, 74% represented males. The mean NIHSS score was 13.11 and BI was 38.87. MDA was significantly higher in stroke patients (7.11 ± 1.67) than in controls (1.64 ± 0.82; p = 0.00). TAP was significantly lower in stroke patients (5.72 ± 1.41) than in controls (8.53 ± 2.4; p = 0.00). The lipid profile and blood sugar levels were also significantly higher in stroke patients. There was no association of MDA and TAP with other variables. Conclusion We found that oxidative stress was associated with acute ischemic stroke. However, we could not establish an association between oxidative stress and the severity of acute stroke.

Introduction: Inflammation is associated with the initiation and progression of cardiovascular diseases. The neutrophil-to-lymphocyte ratio (NLR) has recently emerged as a prognostic marker in cardiovascular diseases. However, impact of NLR on the functional outcome in patients with ischemic stroke remains unclear. Hypothesis: The aim of the study was to investigate the prognostic role of the NLR in patients with acute ischemic stroke. Methods: A consecutive 1,113 patients who were admitted within 7 days after ischemic stroke onset between March 2010 and December 2014 were included for analysis. The patients were categorized into tertiles on the basis of NLR. We evaluated the short-term outcomes using a modified Rankin Scale (mRS) at three-months after onset of ischemic stroke. We divided patients into two groups with favorable outcome (mRS score ≤2) and unfavorable outcome (mRS score ≥3). We compared the clinical characteristics and NLR between two groups. Results: From all the patients included in this study (mean age, 67.8 years; men, 60.0%), 284 (25.5%) patients had unfavorable outcome. The patients with unfavorable outcome were older and more likely to have atrial fibrillation, history of previous stroke, and diabetes mellitus. In addition, participants with unfavorable outcome tended to have lower body mass index and higher initial NIHSS. The percentage values of the tertile 3 were significantly higher in the unfavorable outcome group (28.3% vs. 47.9%, P < 0.001). After adjustment for covariates, the highest tertile were at an exaggerated risk for unfavorable outcome [Odds ratio (95% confidence interval); tertile 3, 1.75 (1.17 - 2.63), P = 0.007]. Conclusions: This study demonstrated that higher NLR predicted worse outcome at 3 months following acute ischemic stroke. This suggests that NLR could be a useful and reliable prognostic biomarker following acute ischemic stroke.

Discharge Disposition

Introduction: Acute ischemic stroke patients receiving IV alteplase (t-PA) within 4.5 hours of symptom onset are 30% more likely to have minimal or no disability at 3 months. During hospitalization, short-term disability is subjectively measured by discharge disposition, whether to home or Inpatient Rehabilitation (IR), Skilled Nursing Facility (SNF) or Sub-acute Care (Sub). There are no studies assessing the role of IV t-PA as a predictor of short-term disability, evidenced by post-stroke disposition. Hypothesis: Low NIHSS is a predictor of high functional status. We assessed the hypothesis that similar to low NIHSS, t-PA predicts post-stroke disposition to a level of care suggestive of high functional status. Methods: All patients with acute ischemic stroke admitted to the UT Service between January 2004 and October 2009 were included. Stratification occurred for age>65, NIHSS and stroke risk factors. Using multivariate logistic regression, the data was analyzed to determine whether there were differences in post-stroke disposition among patients who received t-PA. Results: Patients with mild (NIHSS<8) and moderate (NIHSS 8 to 16) stroke were discharged to the highest level of care in each analysis. Home vs. Other Level of Care Of 2261 patients, 1032 were discharged home, 1229 to another level of care. Patients who received t-PA were 1.7 times more likely to be discharged home (P = <.0001, OR 1.663, 95% CI 1.326 to 2.085). IR vs. SNF Of 1111 patients, 731 patients were discharged to acute IR, 380 to SNF. There were no statistically significant differences in disposition between patients who received t-PA. (P = .0638, OR 1.338, 95% CI 0.983 to 1.822). SNF vs. Sub Of 498 patients, 380 were discharged to SNF, 118 to Sub. There were no significant differences in disposition between patients who received t-PA. Conclusion: Acute stroke patients who receive IV t-PA are more 1.7 times more likely to be discharged home. If post-stroke care is necessary, there is a trend toward rehabilitation at a level reflective of improved functional status (IR vs. SNF). This study is limited by its retrospective nature and the undetermined role of psychosocial factors related to discharge. Prospective studies of time to t-PA therapy in relation to post-stroke disposition are warranted.
