Circulating Soluble CD163: A Potential Predictor for the Functional Outcome of Acute Ischemic Stroke

Background: CD163 is a transmembrane glycoprotein receptor expressed on innate immune cells that sheds from the cell membrane and circulates as a soluble form (sCD163). This study aimed to investigate the circulating levels and clinical relevance of soluble CD163 (sCD163) in acute ischemic stroke (AIS).Methods: This study recruited 300 patients with AIS and 78 healthy controls. The patients were followed up for 1 month to observe the functional outcomes. The neurological functions of the patients were assessed using the NIH Stroke Scale (NIHSS) and the modified Rankin Scale (mRS). The plasma concentrations of sCD163 at the baseline (patient admission) were determined by ELISA.Results: We found that patients with AIS had significantly higher plasma sCD163 concentrations than the healthy control. Patients with high sCD163 concentrations had better functional outcomes than patients with low sCD163 concentrations. The plasma sCD163 concentrations were positively associated with the NIHSS scores and infarction volume at the baseline. The plasma sCD163 was positively associated with the improvement of the NIHSS scores but was negatively associated with the risk of poor functional outcomes during follow-up.Conclusions: These findings indicate that circulating sCD163 is a potential biomarker that is associated with disease severity and the functional outcome of AIS.

Abstract Background It has been shown that eosinophils are decreased and monocytes are elevated in patients with acute ischemic stroke (AIS), but the impact of eosinophil-to-monocyte ratio (EMR) on clinical outcomes among AIS patients remains unclear. We aimed to determine the relationship between EMR on admission and 3-month poor functional outcome in AIS patients. Methods A total of 521 consecutive patients admitted to our hospital within 24 h after onset of AIS were prospectively enrolled and categorized in terms of quartiles of EMR on admission between August 2016 and September 2018. The endpoint was the poor outcome defined as modified Rankin Scale score of 3 to 6 at month 3 after admission. Results As EMR decreased, the risk of poor outcome increased (p < 0.001). Logistic regression analysis revealed that EMR was independently associated with poor outcome after adjusting potential confounders (odds ratio, 0.09; 95% CI 0.03–0.34; p = 0.0003), which is consistent with the result of EMR (quartile) as a categorical variable (odds ratio, 0.23; 95% CI 0.10–0.52; ptrend < 0.0001). A non-linear relationship was detected between EMR and poor outcome, whose point was 0.28. Subgroup analyses further confirmed these associations. The addition of EMR to conventional risk factors improved the predictive power for poor outcome (net reclassification improvement: 2.61%, p = 0.382; integrated discrimination improvement: 2.41%, p < 0.001). Conclusions EMR on admission was independently correlated with poor outcome in AIS patients, suggesting that EMR may be a potential prognostic biomarker for AIS.

Background: Intravenously administered tissue plasminogen activator (IV-TPA) remains the only approved therapeutic agent for arterial recanalization in acute ischemic stroke (AIS). Wide variations in the rates and timing of neurological recovery are observed in thrombolyzed patients. While all IV-TPA treated patients are routinely evaluated for neurological recovery at 24-hours, considerable improvement occurs in some cases within 2-hours of treatment initiation. We evaluated whether early neurological improvement at 2-hours after IV-TPA bolus (ENI-2) can predict functional outcomes in thrombolyzed AIS patients at 3-months. Methods: Data for consecutive stroke patients treated with IV-TPA within 4.5 hours of symptom-onset during 2007-2010 were prospectively entered in the thrombolyzed registry maintained at our tertiary care center. Data were collected for demographic characteristics, vascular risk factors, stroke subtypes and blood pressure levels before IV-TPA bolus. National Institute of Health Stroke Scale (NIHSS) scores were obtained before IV-TPA bolus and at 2-hours. ENI-2 was defined as a reduction in NIHSS score by more than 10-points from baseline score or an absolute score of 4-points or less at 2-hours after IV-TPA bolus. Functional outcomes at 3-months were determined by modified Rankin scale (mRS). Data were analyzed by SPSS 19.0. Results: Of the 2238 AIS patients admitted during the study period, 240 (11%) received IV-TPA within 4.5-hours of symptom-onset. Median age was 65yrs (range 19-92), 63% males, median NIHSS 17points (range 3-35) and median onset-to-treatment time 149 minutes. Overall, 122 (50.8%) patients achieved favorable functional outcome (mRS 0-1) at 3-months. Factors associated with favorable outcome at 3-months on univariable analysis were younger age, female gender, presence of atrial fibrillation, baseline NIHSS, onset-to-treatment time (OTT) and ENI-2. However, multivariable analysis demonstrated NIHSS at onset (OR per 1-point increase 0.907, 95%CI 0.848-0.969) and ENI-2 (OR 4.926 95%CI 1.66-15.15) as independent predictors of favorable outcome at 3-months. Conclusion: Early Neurological improvement at 2-hours after IV-TPA bolus is a strong predictor of the functional outcome at 3-months in acute ischemic stroke patients.

Good Functional Outcome

Abstract Introduction The existence of the smoker’s paradox is controversial and potential mechanisms have not been explained. We aimed to explore the association between cigarette smoking and functional outcome at 3 months in patients with acute ischemic stroke who were treated with intravenous thrombolysis (IVT) or endovascular treatment (EVT). Methods This meta-analysis was conducted in accordance with the PRISMA guidelines. Studies exploring the association between smoking and good functional outcome (modified Rankin Scale score ≤ 2) following IVT or EVT were searched via the databases of PubMed, Embase, and the Cochrane Library from inception to August 8, 2018. Information on the characteristics of included studies was independently extracted by two investigators. Data were pooled using a random-effects or fixed-effects meta-analysis according to the heterogeneity of included studies. Results Among 20 identified studies, 15 reported functional outcomes following IVT, and five reported functional outcomes following EVT. Unadjusted analyses showed that smoking increased the odds of good functional outcomes with a pooled odds ratio (OR) of 1.48 (95% confidence interval [CI]: 1.36–1.60) after IVT and 2.10 (95% CI: 1.47–3.20) after EVT. Of IVT studies, only eight reported outcomes adjusted for covariates and none of the EVT studies reported adjusted outcomes. After adjustment, the relation between smoking and good functional outcome following IVT lost statistical significance (OR 1.14 [95% CI: 0.81–1.59]). Conclusion Our meta-analysis suggested that smoking was not associated with good functional outcome (mRS ≤ 2) at 3 months in patients with acute ischemic stroke who were treated with intravenous thrombolysis. Implications The existence of the smoker’s paradox is controversial. A previous letter by Plas et al. published in 2013 reported a positive result for the association between smoking and good functional outcome at 3 months in acute ischemic stroke patients who received intravenous thrombolysis (IVT). However, a major limitation of their meta-analysis was that the process of data synthesis was based on unadjusted data. Therefore, we conducted this meta-analysis to investigate the association based on adjusted data and a larger sample size. Our meta-analysis suggested that smoking was not associated with good functional outcome after adjusting for covariates.

Introduction: Whether glycemic variability prior to stroke increases the risk of stroke outcomes in prediabetic patients presenting with acute ischemic stroke is still unclear. We evaluated whether pre-stroke glycemic variability, estimated by glycated albumin (GA), increased early neurological deterioration (END) and functional outcomes in prediabetic patients with acute ischemic stroke. Methods: A total of 215 acute ischemic stroke patients with prediabetes were evaluated. The primary outcome was END, defined as an incremental increase in the National Institutes of Health Stroke Scale score by ≥1 point in motor power or ≥2 points in the total score within the 7 days after admission. The secondary outcome was poor functional status defined by a modified Rankin Scale at 3 months. Higher GA (≥16.0%) was determined to reflect glycemic fluctuation prior to ischemic stroke. Results: Of the 215 prediabetic patients, 77 (35.8%) were in the higher GA group. In prediabetic patients, END occurrence and poor functional status were higher in the higher GA group than in the lower GA group. The multivariate analysis showed that a higher GA was associated with an increased risk of END occurrence and poor functional outcomes at 3 months (adjusted odds ratio [95% confidence interval], 4.58 [1.64–12.81], p = 0.004 and 2.50 [1.19–5.25], p = 0.02, respectively). Conclusion: Pre-stroke glycemic variability estimated by GA was associated with END occurrence and poor functional outcome after ischemic stroke in patients with prediabetes.

Abstract Background Low-density lipoprotein cholesterol (LDL-C) can increase cardiovascular risk. However, the association between LDL-C change and functional outcomes in acute ischemic stroke (AIS) patients who underwent reperfusion therapy remains unclear. Methods Patients who received reperfusion therapy were consecutively enrolled. LDL-C measurement was conducted at the emergency department immediately after admission and during hospitalization. The change of LDL-C level (ΔLDL-C) was calculated by subtracting the lowest LDL-C among all measurements during hospitalization from the admission LDL-C. Poor functional outcome was defined as modified Rankin Scale (mRS) > 2 at 90 days. Results A total of 432 patients were enrolled (mean age 69.2 ± 13.5 years, 54.6 % males). The mean LDL-C level at admission was 2.55 ± 0.93 mmol/L. The median ΔLDL-C level was 0.43 mmol/L (IQR 0.08–0.94 mmol/L). A total of 263 (60.9 %) patients had poor functional outcomes at 90 days. There was no significant association between admission LDL-C level and functional outcome (OR 0.99, 95 % CI 0.77–1.27, p = 0.904). ΔLDL-C level was positively associated with poor functional outcome (OR 1.80, 95 % CI 1,12-2.91, p = 0.016). When patients were divided into tertiles according to ΔLDL-C, those in the upper tertile (T3, 0.80–3.98 mmol/L) were positively associated with poor functional outcomes compared to patients in the lower tertile (T1, -0.91-0.13 mmol/L) (OR 2.56, 95 % CI 1.22–5.36, p = 0.013). The risk of poor functional outcome increased significantly with ΔLDL-C tertile (P-trend = 0.010). Conclusions In AIS patients who underwent reperfusion therapy, the decrease in LDL-C level during hospitalization was significantly associated with poor functional outcomes at 90 days.

Introduction: Predicting outcomes of acute stroke patients initially presenting with mild neurologic deficits is important in making decision for thrombolytic therapy. Previous researches with a small sample size have failed to find specific items of NIH Stroke Scale or clinical syndromes to be predictive of functional outcome. Hypothesis: We hypothesized that certain items of the NIH Stroke Scale or their combinations would be independently associated with unfavorable functional outcome after mild stroke Methods: Using a multicenter stroke registry database, we identified patients with acute ischemic stroke who presented within 4.5 hours of symptom onset and had initial NIH Stroke Scale scores ≤ 5. Functional outcomes at three months after the stroke were classified as favorable (modified Rankin Scale score [mRS] 0 to 1) or unfavorable (mRS 2-6). The individual NIH Stroke Scale items were dichotomized as absent (0) or present (≥1) for the analysis. The NIH Stroke Scale items and the total score were tested for predicting the outcomes in multivariable models adjusting for demographics and clinical characteristics. Area under the ROC curve (AUC) was used to assess the performance of multivariable models. Results: Among 2,209 patients who met the eligible criteria, 588 patients (26.6%) exhibited unfavorable functional outcome (mRS 2-6) at three months. The most frequently present items were item 10 (dysarthria, 37.5%), item 4 (facial palsy, 21.1%), item 8 (sensory, 15.0%), and items indicating limb paralysis. Among 15 items of NIH Stroke Scale, all items except for item 8 (sensory) and item 11 (extinction) were significantly associated with unfavorable functional outcomes in bivariate analysis (P <0.05), and many of them remained significant in multivariable analyses. In multivariable analyses, the model including the total NIH Stroke Scale scores exhibited similar AUC (0.759; 95% CI, 0.740 -0.776; P=0.75 for pairwise comparison) compared to the model with all NIH Stroke Scale items (0.758; 0.739 - 0.775) in predicting functional outcomes after the stroke. Conclusions: Simply using the total score was as effective as using all NIH Stroke Scale items in predicting outcomes of patients presented with mild stroke symptom.

OBJECTIVEMetabolite profiling (or metabolomics) can identify candidate biomarkers for disease and potentially uncover new pathways for intervention. The goal of this study was to identify potential biomarkers of functional outcome after subarachnoid hemorrhage (SAH).METHODSThe authors performed high-throughput metabolite profiling across a broad spectrum of chemical classes (163 metabolites) on plasma samples taken from 191 patients with SAH who presented to Massachusetts General Hospital between May 2011 and October 2016. Samples were drawn at 3 time points following ictus: 0–5, 6–10, and 11–14 days. Elastic net (EN) and LASSO (least absolute shrinkage and selection operator) machine learning analyses were performed to identify metabolites associated with 90-day functional outcomes as assessed by the modified Rankin Scale (mRS). Additional univariate and multivariate analyses were then conducted to further examine the relationship between metabolites and clinical variables and 90-day functional outcomes.RESULTSOne hundred thirty-seven (71.7%) patients with aneurysmal SAH met the criteria for inclusion. A good functional outcome (mRS score 0–2) at 90 days was found in 79 (57.7%) patients. Patients with good outcomes were younger (p = 0.002), had lower admission Hunt and Hess grades (p < 0.0001) and modified Fisher grades (p < 0.0001), and did not develop hydrocephalus (p < 0.0001) or delayed cerebral ischemia (DCI) (p = 0.049). EN and LASSO machine learning methods identified taurine as the leading metabolite associated with 90-day functional outcome (p < 0.0001). Plasma concentrations of the amino acid taurine from samples collected between days 0 and 5 after aneurysmal SAH were 21.9% (p = 0.002) higher in patients with good versus poor outcomes. Logistic regression demonstrated that taurine remained a significant predictor of functional outcome (p = 0.013; OR 3.41, 95% CI 1.28–11.4), after adjusting for age, Hunt and Hess grade, modified Fisher grade, hydrocephalus, and DCI.CONCLUSIONSElevated plasma taurine levels following aneurysmal SAH predict a good 90-day functional outcome. While experimental evidence in animals suggests that this effect may be mediated through downregulation of pro-inflammatory cytokines, additional studies are required to validate this hypothesis in humans.

AbstractBackgroundWhether an association exists between cerebral microbleeds (CMBs) and functional recovery after ischemic stroke is unclear. We aimed to evaluate the association between CMBs and functional outcome after acute ischemic stroke.MethodsConsecutive patients with acute stroke were enrolled, and all patients were stratified into good and poor functional outcome groups at discharge and 6 months after ischemic stroke by using a modified Rankin Scale score. Cardiovascular risk factors, CMBs, and white matter hyperintensities were compared between these two outcome groups. Logistic regression analysis was used to estimate the risk of poor functional outcomes.ResultsA total of 225 patients were enrolled, 121 of whom were classified as having a good functional outcome at discharge and 142 as having a good 6-month functional outcome. The presence of CMBs was associated with a poor functional outcome at discharge [CMBs (+) patients in poor vs. good functional group; 48.1% vs. 30.6%; p=0.007] and 6 months [53.0% vs. 30.3%; p=0.001]. After adjustment for confounding factors, only the presence of infratentorial CMBs was associated with a poor functional outcome at discharge and 6 months. The poor functional outcome group had more CMBs than the good outcome group at 6 months.ConclusionsInfratentorial cerebral microbleeds were significantly associated with worse functional outcomes not only in the early phase of ischemic stroke but also in the chronic phase. These findings suggest that the presence of infratentorial CMBs can predict poor functional outcome after acute ischemic stroke.

Background and Purpose: The main premise of reperfusion therapy in acute ischemic stroke (AIS) is to prevent the conversion of the salvable penumbra into irreversible infarct core thereby reducing the final stoke size. Indeed, previous studies have demonstrated a strong correlation between final infarct volumes and functional outcomes. We sought to establish the optimal final infarct thresholds that best correlate with independent functional outcomes. Methods: Multicenter retrospective analysis across five large academic centers. Consecutive patients meeting the following criteria were included: (1) anterior circulation stroke; (2) available final stroke imaging volumetric analysis; (3) available modified Rankin scale (mRS) score at 90 days. Receiver operating characteristic (ROC) curves were created to help defining the optimal final stroke volume points that discriminate a 90-day mRS ≤2. Results: A total of 484 consecutive patients were identified. The mean age was 65.6±14.6 years. The mean baseline NIHSS was 14.2±7.1. The mean final stroke volume was 77.7±88.5cc (median, 40.5cc). A total of 201 out of the 484 (41.5%) of the patients achieved functional independence at 90 days. The ROC analysis demonstrated that final infarct volume (FIV) was a strong discriminator of independent outcomes with an area under the curve [AUC] of 0.778. The best cut-off point for discriminating 90-day mRS ≤2 was 35cc of FIV (70% specificity; 70% sensitivity). The AUC could be improved by excluding older patients. In patient <65 years, the AUC was 0.844 with an optimal discriminating point at 53cc (75% specificity; 75% sensitivity). The exclusion of patients >80 years yielded an AUC of 0.797 with an optimal FIV discriminating point at 40cc (72% specificity; 72% sensitivity). In this population, FIV of 29cc had 80% specificity and 62% sensitivity whereas FIV of 15cc had 90% specificity but only 40% sensitivity for an independent functional outcome. Conclusions: Final infarct volume is a strong surrogate for good outcomes after AIS. Our data suggest that the exclusion of patients with infarct volumes >35-40cc on baseline imaging may enhance the chances of a positive confirmatory clinical trial of reperfusion in AIS.

The aim of our study was to evaluate the role of morphogenetic variability in functional outcome of patients with ischemic stroke. The prospective study included 140 patients with acute ischemic stroke, all of whom were tested upon: admission; discharge; one month post-discharge; and three months post-discharge. The age was analyzed, as well. The Functional Independence Measure (FIM) test and the Barthel Index (BI) were used for the evaluation of functional outcomes for the eligible participants. We analyzed the presence of 19 homozygous recessive characteristics (HRC) in the studied individuals. There was a significant change in FIM values at discharge (p = 0.033) and in BI values upon admission (p = 0.012) with regards to the presence of different HRCs. Age significantly negatively correlated for the FIM score and BI values at discharge for the group with 5 HRCs (p < 0.05), while for BI only, negative significant correlation was noticed for the group with 5 HRCs at three months post-discharge (p < 0.05), and for the group with 3 HRCs at one month post-discharge (p < 0.05) and three months post-discharge (p < 0.05). Morphogenetic variability might be one among potentially numerous factors that could have an impact on the response to defined treatment protocols for neurologically-impaired individuals who suffered an ischemic stroke.
