Background: Lipoprotein A (Lp(a)) is a risk factor for vascular disease; however, few studies have examined the relationship between serum levels of Lp(a) and patient outcomes in acute ischemic stroke (AIS). In this study, we sought to assess whether AIS patients with elevated Lp(a) levels exhibit characteristic differences in stroke severity, in-hospital complications, and short-term outcomes as compared to patients with normal Lp(a) levels. Methods: From our prospective stroke registry, patients consecutively admitted and diagnosed with AIS 07/2008-10/2013 were included if Lp(a) levels were measured during admission. Regressions, adjusting for key covariates, analyzed outcomes in patients with elevated (+) and severely elevated (++) Lp(a) with respect to normal (-) Lp(a). The primary outcome was poor functional outcome (modified Rankin Scale > 2) on discharge. Results: Among the 1,453 patients in our stroke registry, 159 patients met our inclusion criteria; 24 patients (15.1%) were in the +Lp(a) group and 37 patients (23.3%) in the ++Lp(a) group. After adjustment for total cholesterol, LDL, HDL, and triglycerides, patients with ++Lp(a) were more than twice as likely to experience poor functional outcome (OR=2.48, 95% CI 1.0781-5.7231, p=0.033) as those with -Lp(a). Adjusting for age, NIHSS baseline, history of diabetes, admission glucose level, and tPA administration, patients with ++Lp(a) were more than 2.5 times more likely to experience poor functional outcome (OR=2.59, 95% CI 1.0129-6.6282, p=0.047) as compared to those with -Lp(a). Conclusions: Lp(a) elevation predicts higher odds of poor functional outcomes for patients with AIS compared to patients with normal levels. Our findings support the utility of Lp(a) level as a clinically useful biomarker in the development of patient risk profiles.

The aim was to investigate the relationship between retinol-binding protein 4 (RBP4) levels and short-term functional outcome, and to determine its possible role in acute ischemic stroke (AIS). In a prospective observational study, 299 first-ever AIS who were admitted to our hospital were included. Serum levels of RBP4 were assayed and severity of stroke was evaluated with the National Institutes of Health Stroke Scale (NIHSS) score on admission. The prognostic value of RBP4 to predict the poor outcome within 3 months was compared with the NIHSS and with other known outcome predictors. The median age of the included patients was 66 (interquartile range (IQR): 55–77) years and 155 (51.8%) were women. A poor functional outcome was found in 88 patients (29.4%), and significantly higher RBP4 values were found in poor outcomes rather than good outcomes patients (P<0.001). The poor outcomes distribution across the RBP4 quartiles ranged between 9.3% (first quartile) and 60.8% (fourth quartile). In multivariate models comparing the second(Q2), third, and fourth quartiles against the first quartile of the RBP4, RBP4 in Q3 and Q4 were associated with poor functional outcome, and increased risk of poor functional outcome by 144% (OR: 2.44; 95% confidence interval (CI): 1.22–5.03) and 602% (7.02; 3.11–12.24), respectively. Interestingly, RBP4 improved the NIHSS score (area under the curve (AUC) of the combined model, 0.79; 95% CI: 0.74–0.85; P<0.001). The data showed that elevated serum levels of RBP4 at admission were associated with severity and prognosis of AIS, suggesting that vitamin A metabolism or impaired insulin signaling could be involved.

Abstract Background Elevated level of D-dimer increases the risk of ischemic stroke, stroke severity and progression of stroke status, but the association between D-dimer and functional outcome is unclear. The aim of this study is to investigate whether Plasma D-dimer level is a determinant of short-term poor functional outcomes in patients with acute ischemic stroke (AIS). Methods This prospective study included 877 patients with AIS provided plasma D-dimer level after stroke onset. Patients were categorized per D-dimer level: Quartile 1(≤0.24 mg /L), Quartile 2 (0.25–0.56 mg /L), Quartile 3 (0.57–1.78 mg /L), and Quartile 4 (>1.78mg /L). Each patient’s medical record was reviewed, and demographic, clinical, laboratory and neuroimaging information was abstracted. Functional outcome at 90 days was assessed with the modified Rankin Scale (mRS). Results Of 877 patients were included (mean age, 64 years; male, 68.5%), poor outcome was present in 302 (34.4%) patients. After adjustment for potential confounding variables, higher D-dimer level on admission was associated with poor outcome (adjusted odds ratio [aOR] 2.257, 95% CI1.349-3.777 for Q4:Q1; P trend = 0.004). According to receiver operating characteristic (ROC) analysis, the best discriminating factor was a D-dimer level ≥0.315 mg/L for pour outcome [area under the ROC curve (AUC) 0.657; sensitivity 83.8%; specificity 41.4%]. Conclusion Elevated plasma D-dimer level on admission was significantly associated with increased poor outcome after admission for AIS, suggesting the potential role of D-dimer as a predictive marker for short-term poor outcomes in patients with AIS.

Background and Purpose: Treatment with Selective Serotonin Reuptake Inhibitors (SSRIs) following acute ischemic stroke was shown to improve functional and motor recovery independently of depression, possibly mediated by long-term mechanisms such as increased brain plasticity. In animal studies, chronic SSRI treatment is superior over short-term SSRI in evoking neurogenesis but the applicability of this observation to humans remains unelucidated. We hypothesized that pre-treatment with SSRI in acute ischemic stroke patients is associated with improved recovery compared to post-stroke SSRI. Subjects and Methods: We performed an exploratory analysis in consecutive acute ischemic stroke patients who were pre-treated or treated de novo either with fluoxetine, citalopram or escitalopram. Effects of SSRI-pre-treatment on short-term clinical (total NIHSS and NIHSS motor items) and functional (mRS) outcome at discharge compared to post-stroke SSRI were assessed using bivariate and multivariate analyses. Results: Of 2653 patients screened, 239 were included (aged 69±14 years, mean±SD; 42% men, baseline median NIHSS 7 [IQR, 10]). Compared to post-stroke SSRI (n=188), in the SSRI pre-treatment group (n=51) favorable functional outcome at discharge (mRS≤2) was more frequent (41% vs. 20%; p=0.002), duration of hospitalization was shorter (median: 7 versus 11 days; p<0.0001), and there was a non-significant trend toward improved motor recovery (decrease in NIHSS motor items ≥2 points or 0-1 at discharge; 63% vs. 49%; p=0.08). However there was no such difference in total NIHSS recovery (≥4 points or 0-1 at discharge; p=n.s.). Pre-treatment with SSRI was an independent predictor of favorable functional outcome (mRS≤2) at discharge (OR: 4.00; 95%CI: 1.68-9.57; p=0.002) after adjusting for age, pre-stroke mRS, baseline NIHSS and IV-thrombolysis. Conclusions: Our data suggest that pre-treatment with SSRI may be linked to early clinical recovery after acute ischemic stroke and support the hypothesis that pre-stroke SSRI might be superior to post-stroke SSRI.

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.
