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 A number of emerging studies have evaluated clot composition in acute ischemic stroke. Studies of clot composition of embolic strokes of undetermined strokes are lacking. Objectives We sought to analyze the RBC to platelet ratios in clots and correlated our findings with stroke etiology. Methods This was a prospective study analyzing clots retrieved by mechanical thrombectomy in acute ischemic stroke patients at our institution. All clots were stained and scanned at 200x magnification by using a Scanscope XT digital scanner (Apergio, Vista, California). Image-J software (National Institutes of Health, Bethesda, Maryland) was used for semi quantitative analysis of percentage RBC’s and platelets. Unpaired t-test was used to compare means of RBC to Platelet ratios. Correlation of RBC to Platelet ratios with stroke etiology was performed. Results A total of 33 clots from 33 patients were analyzed. Stroke etiology was undetermined in 6 patients, cardioembolic in 14, large vessel atherosclerosis (LVA) in 9, and carotid dissection in 4. The mean RBC to platelet ratio was 0.78:1 (+/− 0.65) in cardioembolic clots, 1.73:1 (+/− 2.38) in LVA and 1.4:1(+/− 0.70) in carotid dissections. Although patients with undetermined etiology had a similar clot composition to cardioembolic stroke (0.36:1+/− 0.33), (p = 0.19), it differed significantly from LVA and dissections respectively (p = 0.037, p = 0.01). Conclusion In our study, a low RBC to Platelet ratio was found among patients with embolic strokes of undetermined source, however shared similar characteristics with cardioembolic thrombi. Ongoing collection and analysis is needed to confirm these findings and its significance in evaluating stroke etiology.

Background: Blood pressure variability (BPV) is associated with target organ damage progression and increased cardiovascular events, including stroke. The aim of this study was to evaluate the associations between short-term BPV during acute periods and recanalization degree, early neurological deterioration (END) occurrence, and functional outcomes in acute ischemic stroke patients who had undergone intra-arterial thrombectomy (IAT). Methods: We retrospectively analyzed 303 patients with large vessel occlusive stroke who underwent IAT. The following BPV parameters, measured over 24 and 48 h after IAT, were compared: the mean, SD, coefficient of variation (CV), variation independent of the mean (VIM) for both the systolic BP (SBP) and diastolic BP, and the proportion of nocturnal SBP risers. Results: BPV parameters decreased with higher recanalization degree. The mean SBP (SBPmean) over 24 and 48 h after IAT, and the SD of SBP (SBPSD), CV of SBP (SBPCV), and VIM of SBP (SBPVIM) during the 48 h following the procedure had significant associations with recanalization degree. Patients with END had higher BPV than that of those without END, and the difference was more evident for incomplete recanalization. Increased BPV was associated with a shift toward poor functional outcome at 3 months after adjustment, including recanalization degree (OR range for significant parameters, 1.26–1.64, p = 0.006 for 48 h SBPmean, p = 0.003 for 48 h SBPCV, otherwise p < 0.002). Conclusions: Short-term BPV over 24 and 48 h after IAT in acute ischemic stroke patients was related to recanalization degree, and END occurrence, and may be an independent predictor of clinical outcome.

 CORRELATION BETWEEN NEUTROFIL LIMPHOCYTE RATIO AND CEREBRAL INFARCTION VOLUME IN ACUTE ISCHAEMIC STROKEABSTRACTIntroduction: Inflammation plays a key role in stroke pathophysiology. Neutrophils is one of the earliest leucocyte subtypes to infiltrate the ischemia area of the brain. The neutrophil-lymphocyte ratio (NLR) is independent of the severity of coronary heart disease and as a predictor of poor clinical outcomes in patients with coronary heart disease undergoing angiography. The neutrophil-lymphocyte ratio values may be a prognostic factor in ischemic stroke patients. The neutrophil- lymphocyte ratio values can also be used in predicting infarct size, however limited study has been conducted in this area.Aim: To determine the correlation of NLR with cerebral infarct volume in acute ischemic stroke patients.Method: This was an analytical observational study with cross sectional design. The population for this study were acute ischemic stroke patients at NTB Genereal Hospital. The collected data were analyzed by Spearman correlation test.Results: Approximately 52 participants  were enrolled in this study with mean age was 59.79±8.65 years old. Hypertension was a common modifiable risk factor identified in more than 94.2 % participant. The mean of neutrophil lymphocyte ratio was 3.94±2.96 and mean of infarct volume was 13.96±37.26cm3. There was correlation between RNL and cerebral infract volume (r=+0.351; p=0.023).Discussions: Higher lymphocyte neutrophil ratio in acute ischemic stroke patients would result in an increase of brain infarct volume.Keyword: Infarct volume, ischaemic stroke, neutrophil lymphocyte ratioABSTRAKPendahuluan: Inflamasi memegang peranan penting dalam patofisiologi stroke.

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: Stroke is the leading cause of morbidity and mortality in Indonesia. Dyslipidemia is one of the main risk factors of ischemic stroke. Atherogenic index of plasma (AIP) is the logarithm of the triglyceride’s plasma ratio concentration to high density lipoprotein cholesterol (HDL-C) plasma concentration. Previous studies showed that the high AIP at hospital admission was associated with deterioration of neurological deficits in patients with acute ischemic stroke.Methods: This is a cross sectional study with 82 sample of acute ischemic stroke subjects that consecutively collected from the medical records of Haji Adam Malik general hospital Medan from January to December 2019, AIP assessment performed at the 1st day of hospitalization and then at the 7th -onset the national institutes of health stroke scale (NIHSS) score assessment was count. Data analysis is conducted with Spearman test.Results: Demographic characteristics showed that most subjects were female (51.2%), at age range between 60 -68 years (30.5%), had high school education level (48.8%), self-employed (35.4%) and Bataknese (68.3%). The mean of AIP was 0.15±0.26 and the mean NIHSS score was 6.70±3.6. There was a positive significant and mild power of correlation between AIP and the NIHSS score (p=0.017; r=0.262).Conclusions: There is a significant relationship between AIP and the NIHSS score. The higher the AIP of acute ischemic stroke patients was associated with the increase in the NIHHS scores.
