Aims It is unclear whether thyroid hormones are associated with functional outcome after ischemic stroke. We aimed to investigate the impact of thyroid hormones at admission on functional outcome at 3 months after acute ischemic stroke. Methods A total of 480 consecutive patients for ischemic stroke within 48 hours of onset were enrolled in this study. Thyroid hormones including thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroxine (FT4) were measured at admission and functional outcomes were assessed at 3 months with the modified Rankin Scale (mRS) ranging from 0 to 6. Poor outcome was defined as mRS≥3. Results FT3 levels at admission were considerably lower in poor outcome patients than those with good outcome at 3 months (3.53±0.70pmol/L vs 4.04±0.68pmol/L, respectively; P＜0.001). Lower levels of FT3 were observed with higher mRS scores. Multivariable logistic regression analysis revealed that FT3 levels were significantly associated with risk of poor outcome at 3 months independent of conventional risk factors such as age, NIHSS score and recanalized therapy. In addition, patients in the bottom quartile of FT3 levels had a 2.56-fold higher risk of developing poor outcome compared with patients in the top quartile (OR=2.56; 95%CI 1.15-5.69, p =0.021). The sensitivity and specificity of FT3 (≤3.69pmol/L) predicting poor outcome were 62.70% and 72.03% respectively. Conclusion Our study suggests that FT3 levels at admission are significantly and independently associated with risk of poor outcome after ischemic stroke and lower FT3 levels can be regarded as a prognostic biomarker for poor outcome at 3 months.

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.

Abstract Background The impact of elevated total homocysteine (tHcy) on functional outcomes and pneumonia after acute ischemic stroke (AIS) is still not well understood. We investigated the association between tHcy levels upon hospital admission and in-hospital short-term outcomes in AIS patients. Methods A total of 2,084 AIS patients enrolled from December 2013 to May 2014 across 22 hospitals in Suzhou city were included in the present study. We divided patients into 4 groups according to their level of admission tHcy: Q1 (<9.70 umol/L), Q2 (9.70-12.3 umol/L), Q3 (12.3-16.9 umol/L), and Q4 (≥16.9 umol/L). Logistic regression models were used to estimate the effect of tHcy on the short-term outcomes, including in-hospital pneumonia, all cause in-hospital mortality and poor outcome upon discharge (modified Rankin Scale score ≥3) in AIS patients. Results During hospitalization, 332 patients (15.9%) had pneumonia, 57 patients (2.7%) died from all causes and 784 (37.6%) patients experienced poor outcome at discharge. The risk of in-hospital pneumonia was significantly higher in patients with highest tHcy level (Q4) compared to those with lowest (Q1) (adjusted odds ratio [OR] 1.55; 95% confidence interval [CI], 1.03-2.33; P -trend =0.019). The highest tHcy level (Q4) was associated with a 3.35-fold and 1.50-fold increase in the risk of in-hospital mortality(adjusted OR 3.35; 95% CI, 1.11–10.13; P -trend =0.015) and poor outcome upon discharge(adjusted OR 1.50; 95% CI, 1.06–2.12; P -trend =0.044) in comparison to Q1 after adjustment for potential covariates including pneumonia. Subgroup analyses further confirmed a significant association between higher tHcy levels and a high risk of short-term outcomes. Conclusions Having a high admission tHcy level was independently associated with in-hospital pneumonia, all cause in-hospital mortality and poor outcome upon discharge in AIS patients. Moreover, the association between higher tHcy and poor functional outcome was not modified by pneumonia.

Introduction: The role of matrix metalloproteinase 9 (MMP-9) and cellular fibronectin (c-Fn) in acute ischemic stroke is controversial. We systematically reviewed the literature to investigate the association of circulating MMP-9 and c-Fn levels and MMP-9 rs3918242 polymorphism with the risk of three outcome measures after stroke.Methods: We searched English and Chinese databases to identify eligible studies. Outcomes included severe brain edema, hemorrhagic transformation, and poor outcome (modified Rankin scale score ≥3). We estimated standardized mean differences (SMDs) and pooled odds ratios (ORs) with 95% confidence intervals (CIs).Results: Totally, 28 studies involving 7,239 patients were included in the analysis of circulating MMP-9 and c-Fn levels. Meta-analysis indicated higher levels of MMP-9 in patients with severe brain edema (SMD, 0.76; 95% CI, 0.18–1.35; four studies, 419 patients) and hemorrhagic transformation (SMD, 1.00; 95% CI, 0.41–1.59; 11 studies, 1,709 patients) but not poor outcome (SMD, 0.30; 95% CI, −0.12 to 0.72; four studies, 759 patients). Circulating c-Fn levels were also significantly higher in patients with severe brain edema (SMD, 1.55; 95% CI, 1.18–1.93; four studies, 419 patients), hemorrhagic transformation (SMD, 1.75; 95% CI, 0.72–2.78; four studies, 458 patients), and poor outcome (SMD, 0.46; 95% CI, 0.16–0.76; two studies, 210 patients). Meta-analysis of three studies indicated that the MMP-9 rs3918242 polymorphism may be associated with hemorrhagic transformation susceptibility under the dominant model (TT + CT vs. CC: OR, 0.621; 95% CI, 0.424–0.908; P = 0.014). No studies reported the association between MMP-9 rs3918242 polymorphism and brain edema or functional outcome after acute stroke.Conclusion: Our meta-analysis showed that higher MMP-9 levels were seen in stroke patients with severe brain edema and hemorrhagic transformation but not poor outcome. Circulating c-Fn levels appear to be associated with all three outcomes including severe brain edema, hemorrhagic transformation, and poor functional outcome. The C-to-T transition at the MMP-9 rs3918242 gene appears to reduce the risk of hemorrhagic transformation.

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: A number of studies have explored the prognostic role of CRP in patients with acute ischemic stroke, however, the results have been inconclusive. The aim of our study was to investigate the impact of infection on the association between CRP and 3-month functional outcome by performing a registry study and systematic review. Methods: Patients admitted within 24 hours of acute ischemic stroke onset and had CRP measured within 24 hours after admission were included. Patients admitted between June 2016 and December 2018 in Chengdu Stoke Registry were enrolled. The PubMed database was searched up to July 2019 to identify eligible studies. Poor outcome was defined as modified Rankin Scale scores at 3-month more than 3. Results: Totally, 368 patients in the registry and 18 studies involving 15238 patients in the systematic review were included. A statistically significant association between CRP values on admission and 3-month poor outcome in patients without infection was found, both in our registry (CRP per 1-mg/L increment, OR 1.04, 95% CI 1.01 to 1.07, p=0.008) and meta-analysis (CRP per 1-mg/dL increment, OR 1.66 [95% CI 1.37 to 2.01, p<0.001]). In patients with infection, CRP was not associated with a 3-month poor outcome according to registry data (OR 1.00, 95% CI 0.99 to 1.01, p=0.663) and meta-analysis (OR 1.01, 95% CI 0.99 to 1.01, p=0.128). Conclusion: High CRP value was independently associated with a 3-month poor outcome after stroke in patients without infection. Further studies are required to examine the value of infection on CRP measures and long-term functional outcomes.

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.

This study evaluated the prognostic value of thyroid-related hormones within normal ranges after acute ischemic stroke. This was a retrospective study and we reviewed 1072 ischemic stroke patients consecutively admitted within 72 h after symptom onset. Total triiodothyronine (T3), total thyroxine (T4), free T3, free T4, and thyroid-stimulating hormone (TSH) were assessed to determine their values for predicting functional outcome at the first follow-up clinic visits, which usually occurred 2 to 4 weeks after discharge from the hospital. 722 patients were finally included. On univariate analysis, poor functional outcome was associated with presence of atrial fibrillation as the index event. Furthermore, score of National Institutes of Health Stroke Scale (NIHSS), total T4, free T4, and C-reactive protein at admission were significantly higher in patients with poor functional outcome, whereas free T3 and total T3 were significantly lower. On multiple logistic regression analysis, lower total T3 concentrations remained independently associated with poor functional outcome [odds ratio (OR), 0.10; 95% confidence interval (CI), 0.01–0.84;P=0.035]. The only other variables independently associated with poor functional outcome were NIHSS scores. In sum, lower total T3 concentrations that were within the normal ranges were independently associated with poor short-term outcomes.

The aim of this study is to investigate whether Plasma D-dimer level is a determinant of short-term poor functional outcome in patients with acute ischemic stroke (AIS). Methods: This prospective study included 877 Chinese patients with AIS admitted to Renmin Hospital of Wuhan University within 72 hours of symptom onset. Patients were categorized per plasma 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 plasma 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 plasma 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 plasma D-dimer as a predictive marker for short-term poor outcome in patients with AIS.

Background: We investigated the association between serum levels of glial fibrillary acidic protein (GFAP) and stroke functional outcomes in a cohort of 286 patients with acute ischemic stroke (AIS). Methods: We prospectively studied 286 patients with AIS who were admitted within 24 h after the onset of symptoms. Serum levels of GFAP and National Institutes of Health Stroke Scale (NIHSS) were measured at admission. The primary end point was stroke functional outcome among 1-year after stroke onset. We used logistic regression models to assess the relationship between GFAP levels and stroke outcomes. Results: The GFAP level was obtained with a median value of 0.18 (interquartile ranges (IQRs): 0.09–0.28) ng/ml. In multivariable models adjusted for age, gender, and other risk factors, GFAP levels were associated with an increased risk of a NIHSS>6 (odds ratio (OR) = 1.55; 95% confidence interval (CI): 1.16–1.89; p = 0.012). The poor outcome distribution across the GFAP quartiles ranged between 12.7% (first quartile) and 70.4% (fourth quartile). After adjusting for other established risk factors, in multivariate models comparing the Q3 and Q 4 quartiles against the Q1 of the GFAP, the levels of GFAP were associated with poor outcome, and the adjusted risk of poor outcome increased by 211% (3.11[1.80–5.05], p < 0.001) and 522% (6.22[2.98–11.83], p < 0.001), respectively. Interestingly, GFAP improved the ability of NIHSS score to diagnose poor outcomes (area under the curve [AUC] of the combined model 0.82; 95% CI: 0.77–0.88; p = 0.02). Conclusion: GFAP levels are a novel and complementary biomarker to predict functional outcome 1 year after AIS
