Abstract
Background Ischemic stroke is a common type of stroke that leads to death and functional disability in hypertensive patients. However, there are no well-studied non-invasive and less expensive fluid biomarkers routinely used to detect ischemic stroke in hypertensive patients. Hence, this study aimed to tease out the performance of D-dimer, fibrinogen, and the D-dimer to fibrinogen ratio (DDFR) in predicting hypertension-associated acute ischemic stroke. Methods A hospital-based cross-sectional study was done from October 2022 to January 2022 at Yikatit 12 Hospital Medical College, Ethiopia. We recruited 55 hypertensive patients who had an ischemic stroke and 110 who did not. A ROC curve was used to calculate the areas under the curves (AUCs) and determine the diagnostic power of the D-dimer, fibrinogen, and DDFR. The Youden index was used to find the best cut-off points for biomarkers in detecting acute ischemic stroke. A De Long test was employed to show whether there was a significant difference between the AUCs of biomarkers in diagnosing ischemic stroke. Results D-dimer yielded the highest diagnostic power (AUC = 0.776) in detecting acute ischemic stroke, followed by DDFR (AUC = 0.763) and fibrinogen (AUC = 0.694), but there was no significant difference between them. At 0.52 μg/ml cut-off point, D-dimer had 82.9% sensitivity, 66.7% specificity, 62.5% PPV, and 85.3% NPV to diagnose acute ischemic stroke. Fibrinogen could detect acute ischemic stroke at 405.85 mg/dl level, with 70.0% sensitivity, 57.1% specificity, 41.2% PPV and 81.6% NPV. At a 1.83 ratio, DDFR might also identify ischemic stroke with 80.0% sensitivity, 67.1% specificity, 51.1% PPV, and 88.7% NPV. Conclusion We showed D-dimer, fibrinogen, and DDFR as promising, affordable, and non-invasive biomarkers for the detection of ischemic stroke among subjects with hypertension. This will help clinicians make an early diagnosis and better guide patient therapy.

Inflammation-associated D-dimer predicts neurological outcome of recent small subcortical infarct: A prospective clinical and laboratory study. Clin Neurol Neurosurg 2024; 237:108126. [PMID: 38290168 DOI: 10.1016/j.clineuro.2024.108126] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Revised: 01/14/2024] [Accepted: 01/17/2024] [Indexed: 02/01/2024]
Abstract
OBJECTIVE Elevated level of D-Dimer often indicates a worse prognosis in cerebral infarction. However, there is limited research on this impact within recent small subcortical infarction (RSSI). We aim to explore the role of inflammation and the total magnetic resonance imaging (MRI) burden of cerebral small vessel disease (cSVD) in this process. METHODS 384 RSSI patients and 189 matched healthy controls were strictly registered in the current research. We evaluated short-term and long-term outcomes by measuring the percentage of the National Institutes of Health Stroke Scale (NIHSS) improvement and the modified Rankin Scale (mRS) at 3 months, respectively. We also assessed the chronic, sustained brain damage associated with cSVD using the total MRI burden and confirmed the relationship between prognosis and the total MRI burden of cSVD. Furthermore, we explored the associations between D-dimer and C-reactive protein (CRP) levels with NIHSS improvement and mRS at 3 months, as well as their relationships with both the total MRI burden of cSVD and its 4 imaging features. RESULTS Both NIHSS improvement and the mRS at 3 months were found to be correlated with the total MRI burden of cSVD. Higher D-dimer and CRP levels showed a linear correlation, indicating worse prognosis and a higher total MRI burden of cSVD. The four imaging features of the total MRI burden of cSVD did not exhibit entirely consistent patterns when exploring their correlations with prognosis and laboratory indicators. CONCLUSION Inflammation-associated D-dimer predicts neurological outcomes in patients with recent small subcortical infarct, and reflects a more severe total MRI burden of cSVD.

Abstract
This study investigated prognostic factors in elderly patients (80 years and older) undergoing mechanical thrombectomy (MT) for anterior circulation large vessel occlusion (LVO) in acute stroke treatment. Of 59 cases, 47.5% achieved a favorable outcome (mRS ≤ 3) at three months, with a mortality rate of 20.3%. Factors associated with better outcomes included younger age, lower admission National Institute of Health Stroke Scale (NIHSS) scores, lower N-terminal pro-brain natriuretic peptide (NT-proBNP) and D-dimer levels, the presence of the first pass effect (FPE), and successful recanalization. However, logistic regression showed that only lower admission NIHSS scores were significantly correlated with favorable outcomes. In addition, this study suggests that lower admission NT-proBNP and D-dimer levels could potentially serve as prognostic indicators for elderly LVO patients undergoing MT.

J Clin Med 2023; 12:6289. [PMID: 37834933 PMCID: PMC10573512 DOI: 10.3390/jcm12196289] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2023] [Revised: 09/20/2023] [Accepted: 09/27/2023] [Indexed: 10/15/2023] Open
Abstract
We aimed to evaluate the association between preprocedural D-dimer levels and endovascular and clinical outcomes. We retrospectively reviewed patients with acute intracranial large-vessel occlusion who underwent mechanical thrombectomy. Plasma D-dimer levels were measured immediately before the endovascular procedure. Endovascular outcomes included successful recanalization, first-pass recanalization (first-pass effect (FPE) and modified FPE (mFPE)), thrombus fragmentation, and the number of passes of the thrombectomy device. Clinical outcomes were assessed at 3 months using the modified Rankin Scale. A total of 215 patients were included. Preprocedural D-dimer levels were lower in patients with FPE (606.0 ng/mL [interquartile range, 268.0-1062.0]) than in those without (879.0 ng/mL [437.0-2748.0]; p = 0.002). Preprocedural D-dimer level was the only factor affecting FPE (odds ratio, 0.92 [95% confidence interval, 0.85-0.98] per 500 ng/mL; p = 0.022). D-dimer levels did not differ significantly based on successful recanalization and thrombus fragmentation. The number of passes of the thrombectomy device was higher (p = 0.002 for trend) and the puncture-to-recanalization time was longer (p = 0.044 for trend) as the D-dimer levels increased. Patients with favorable outcome had significantly lower D-dimer levels (495.0 ng/mL [290.0-856.0]) than those without (1189.0 ng/mL [526.0-3208.0]; p < 0.001). Preprocedural D-dimer level was an independent factor for favorable outcome (adjusted odds ratio, 0.88 [0.81-0.97] per 500 ng/mL; p = 0.008). In conclusion, higher preprocedural D-dimer levels were significantly associated with poor endovascular and unfavorable functional outcomes.

Abstract
Background Cerebral venous sinus thrombosis (CVST) is a form of the cerebrovascular disease characterized by varying degrees of obstruction of veins and cerebral sinuses caused by thrombus. Diagnosis is incredibly challenging due to the wide variety of symptoms and the distinct radiological aspects of affected vessels. In patients with venous thrombosis, the presence of D-Dimer is used as an indicator of the presence of endogenous fibrinolysis. D-Dimer is a by-product of fibrin polymer fragmentation. Objective To investigate the relationship between the level of D-Dimer and the number of sinuses in CVST by Digital Subtraction Angiography (DSA). Methods Retrospective data from September 2021 to September 2022 were used in this analytical observational with a cross-sectional study design. Chi-Square is used for data processing relationship analysis. Results Out of the 54 subjects with elevated levels of D-Dimer, 38 (70.4%) are females, whereas 16 (29.6%) are males. High levels of D-Dimer have been related to a greater risk of sinus thrombosis (p < 0.001). D-Dimer levels were similarly shown to rise in conjunction with the number of sinuses most severely damaged by thrombosis. The most common site for thrombosis to develop in this study were the left sigmoid and left transverse sinuses. Most risk factors were hormonal. Conclusion There is a statistically significant relationship between an increase in the D-Dimer level and the greater number of sinuses involved as determined by DSA in individuals diagnosed with CVST.

Abstract
Objective This research was conducted to discuss the recent prognosis of patients with acute cerebral infarction (ACI) combined with cerebral-cardiac syndrome (CCS). Method Eighty-seven patients with ACI were selected, which were divided into the ACI group (52 patients) and the CCS group (35 patients) according to whether the CCS was combined, and another 30 health controls were selected as the control group. Serum hypoxia-inducible factor (HIF)-1α and vascular endothelial growth factor (VEGF) levels of subjects in each group at the 1st day, the 3rd day, and the 7th day after admission were measured by enzyme-linked immunosorbent assay. After discharge for 30 days, the National Institutes of Health Stroke Scale (NIHSS) and the modified Rankin Scale (mRS) score were utilized to evaluate the prognosis of patients. The role of serum HIF-1α and VEGF levels in the prognosis of ACI combined with CCS patients was assessed by receiver operating characteristic curve and the binary logistic regression analysis. Results Higher serum HIF-1α and VEGF levels were observed in the CCS and ACI groups versus the control group, and the levels of which were even higher in the CCS group in comparison to the ACI group. According to the prognosis of the NIHSS score, fasting blood glucose (FBG), Acute Physiology and Chronic Health Evaluation II score, creatine kinase-MB (CK-MB), and HIF-1α and VEGF levels at the 7th day of admission were higher while Glasgow coma scale (GCS) score was lower in the poor prognosis group than those in the good prognosis group, and the area under the curve (AUC) of serum HIF-1α and VEGF levels was 0.895 (95% confident interval [CI], 0.786-1.000), and 0.855 (95% CI, 0.731-0.980). According to the prognosis of the mRS score, FBG, CK-MB, and HIF-1α and VEGF levels at the 7th day of admission were higher while GCS score was lower in the poor prognosis group than those in the good prognosis group, and the AUC of serum HIF-1α and VEGF levels was 0.850 (95% CI, 0.722-0.979) and 0.901 (95% CI, 0.798-1.000). The results of the binary logistic regression analysis revealed that HIF-1α and VEGF levels may be independent risk factors influencing the prognosis of ACI combined with CCS. Conclusion Serum HIF-1α and VEGF have a good predictive value for assessing the recent prognosis of patients with ACI combined with CCS, which could be independent risk factors influencing the prognosis of disease.

Abstract
OBJECTIVE This study aimed to investigate prognostic factors that affect modified Rankin Scale (mRS) score at 3 months after onset in acute stroke patients with large vessel occlusion (LVO) undergoing endovascular thrombectomy. METHODS We retrospectively examined 87 consecutive patients who underwent endovascular cerebral thrombectomy for acute anterior circulation LVO at Oita University Hospital and Nagatomi Neurosurgery Hospital from January 2014 to December 2020. RESULTS Age, National Institutes of Health Stroke Scale (NIHSS) score, and D-dimer concentration on admission were significant univariate prognostic factors related to mRS score 3 months after stroke onset. Multivariate logistic regression analysis showed that D-dimer concentration was the only significant independent prognostic factor. The area under the receiver operating characteristic curve for D-dimer concentration and mRS score at 3 months was 0.715 (95% confidence interval, 0.599 - 0.831); sensitivity and specificity were 60.6% and 80.0%, respectively, using a 1.9 μg/mL cutoff value. CONCLUSIONS Prognosis may be worse in patients undergoing acute endovascular cerebral thrombectomy with high D-dimer concentration on admission. Other treatment options should be considered for these patients.

Abstract
Objective Investigations on coagulation parameters including fibrinogen (Fbg),
fibrinogen degradation products (FDP), and D-dimer in ischemic stroke
patients treated with intravenous thrombolysis are insufficient. We aimed to
investigate the association between in-hospital clinical outcomes and the
coagulation parameters at different time points in ischemic stroke patients
treated with intravenous tissues plasminogen activator (IV tPA). Methods We retrospectively enrolled patients who received IV tPA therapy within 4.5 h
from symptoms onset. Demographics, clinical characteristics, imaging
measures, and the discharge mRS score were collected. Multivariable logistic
regression analyses were performed to test whether coagulation parameters
were independent predictors for the in-hospital clinical outcomes. We also
employed machine learning models to investigate whether coagulation
parameters were able to improve the prediction of favorable functional
outcomes. Results One hundred and fifty-two patients treated with IV tPA were included. Among
the coagulation parameters, low D-dimers at 48 h proved to be an independent
predictor of favorable functional outcome (adjusted odd ratio 0.24, 95%
confidential intervals 0.06-0.92, P = 0.04). The AUC of D-dimer at 48 h to
predict favorable functional outcome was 0.73 (0.60-0.87) and the optimal
cut-off value was 0.92 (sensitivity 0.69, specificity 0.78). Machine
learning models with D-dimer at 48 h had superior performance in predicting
favorable functional outcomes and among the input variables in the machine
learning models, D-dimer at 48 h showed the highest weight in predicting mRS
0-1 at discharge (38.44%). Conclusion Increased levels of D-dimer at 48 h was associated with lower proportion of
favorable functional outcomes in acute ischemic stroke patients with
intravenous thrombolysis.

Abstract
INTRODUCTION D-dimer is a small protein fragment produced during fibrinolysis. High D-dimer levels were shown to have prognostic impact in critically ill patients. Nevertheless, data regarding D-dimer's prognostic impact among tertiary care intensive coronary care unit (ICCU) patients is scarce. MATERIAL AND METHOD All patients admitted to the ICCU between 1-12/2020 were prospectively included. Based on admission D-dimer level, patients were categorized into low and high D-dimer groups (< 500 ng/ml and ≥ 500 ng/ml) and also to age-adjusted D-dimer cutoff (500 ng/ml for ages ≤ 50 years old and age*10 for ages>50 years old). RESULTS AND DISCUSSION A total of 959 consecutive patients were included, including 296 (27.4%) and 663 (61.3%) patients with low and high D-Dimer levels, respectively. Patients with high D-dimer level were older compared with patients with low D-dimer level (age 70.4 ± 15 and 59 ± 13 years, p = 0.004) and had more comorbidities. The most common primary diagnosis on admission among the low D-dimer group was acute coronary syndrome (ACS) (74.3%), while in the high D-dimer group it was a combination of ACS (33.6%), cardiac structural interventions (26.7%) and various arrhythmias (21.1%). High D-dimer levels were associated with increased mortality rate, even after adjustment for age, gender, comorbidities and left ventricular ejection fraction (LVEF). High D-dimer levels were independently associated with increased overall 1-year mortality rate (HR = 5.8; 95% CI; 1.7-19.1; p = 0.004). CONCLUSION Elevated D-dimer levels on admission in ICCU patients is an independently poor prognostic factor for in-hospital morbidity and 1-year overall mortality rate following hospitalization.

Yuan B, Yang T, Yan T, Cheng W, Bu X. Relationships Between D-Dimer Levels and Stroke Risk as Well as Adverse Clinical Outcomes After Acute Ischemic Stroke or Transient Ischemic Attack: A Systematic Review and Meta-Analysis. Front Neurol 2021; 12:670730. [PMID: 34163426 PMCID: PMC8215146 DOI: 10.3389/fneur.2021.670730] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Accepted: 04/21/2021] [Indexed: 12/03/2022] Open
Abstract
Objective: Abnormal elevation of D-dimer levels is an important indicator of disseminated intravascular clotting. Therefore, we hypothesized that high D-dimer levels were associated with the risk of stroke and adverse clinical outcomes of patients with acute ischemic stroke (AIS) or transient ischemic attack (TIA). Methods: The present meta-analysis aimed to systematically analyze the associations between D-dimer and the risk of stroke as well as the clinical outcomes of patients with post-stroke or TIA. Meanwhile, dose–response analyses were conducted when there were sufficient data available. Three electronic databases including Pubmed, the Embase database, and the Cochrane Library were searched by two investigators independently. All the pooled results were expressed as risk ratios (RRs). Results: Finally, 22 prospective cohort studies were included into this meta-analysis. The results suggested that high D-dimer levels were associated with increased risks of total stroke (RR 1.4, 95%CI 1.20–1.63), hemorrhagic stroke (RR 1.25, 95%CI 0.69–2.25), and ischemic Stroke (RR 1.55, 95%CI 1.22–1.98), and the dose-dependent relationship was not found upon dose–response analyses. Besides, the high D-dimer levels on admission were correlated with increased risks of all-cause mortality [RR 1.77, 95% confidence interval (CI) 1.26–2.49], 5-day recurrence (RR 2.28, 95%CI 1.32–3.95), and poor functional outcomes (RR 2.01, 95%CI 1.71–2.36) in patients with AIS or TIA. Conclusions: On the whole, high D-dimer levels may be associated with the risks of total stroke and ischemic stroke, but not with hemorrhagic stroke. However, dose–response analyses do not reveal distinct evidence for a dose-dependent association of D-dimer levels with the risk of stroke. Besides, high D-dimer levels on admission may predict adverse clinical outcomes, including all-cause mortality, 5-day recurrence, and 90-day poor functional outcomes, of patients with AIS or TIA. More studies are warranted to quantify the effect of D-dimer levels on the risk of stroke or TIA, so as to verify and substantiate this conclusion in the future.

Abstract
: To evaluate analytic and clinical performance of plasma thrombin-antithrombin complex (TAT) and D-dimer assay in assessing the severity and outcome of acute ischemic stroke. The prospective study was conducted and extended from January 2018 to December 2018. A total of 236 patients admitted within 24 h after neurologic symptoms onset were recruited. The median TAT and D-dimer levels were significantly higher in the acute ischemic stroke patients than in the controls. The average TAT levels in patients with mild, moderately severe and severe stroke were 1.75 [interquartile ranges (IQR), 1.1-2.6], 3.3 (IQR, 1.8-4.5) and 13.5 (IQR, 7.2-15.3) ng/ml. The D-dimer levels of respective patient groups were 0.39 (IQR, 0.22-0.73), 0.58 (IQR, 0.39-1.25) and 3.59 (IQR, 1.73-4.74) mg/l. With the optimal cut-off TAT level (1.75 ng/ml) determined from receiver operating characteristic analysis, the Area under the curve (AUC), the sensitivity and specificity of TAT for stroke diagnosis were 0.763, 58.1 and 87.8%. The cut-off D-dimer level was 0.38 mg/l and the AUC, the sensitivity and specificity were 0.772, 60.2 and 88.9%. The Area under the receiver operating characteristic curves (AUROCs) and sensitivity in the moderate to severe stroke increased to 0.903 and 86.9% for TAT, and 0.880 and 80.3% for D-dimer, respectively. Age and high TAT level were significant independent risk factors for stroke severity. Age, high initial National Institutes of Health Stroke Scale score and high TAT level were significant independent poor prognostic factors on multivariate analysis. TAT and D-dimer were superior in separating the moderate-to-severe stroke than mild stroke. A high TAT plasma level is an independent predictor for stroke severity and poor prognosis during 1-month follow-up.

Abstract
BACKGROUND AND PURPOSE Improving prehospital triage of large vessel occlusion (LVO) would reduce time to reperfusion therapies. We aimed to study early predictors of LVO in acute ischemic stroke to identify candidates for endovascular treatment. METHODS The Stroke-Chip was a prospective observational study conducted at 6 Stroke Centers in Catalonia. Blood samples were obtained in the first 6 hours from symptom onset of consecutive patients. Stroke severity was evaluated with National Institutes of Health Stroke Scale (NIHSS) and LVO was assessed. Independent association of multiple blood biomarkers with LVO was evaluated using logistic regression models adjusted by covariates. Sensitivity, specificity, and predictive values were assessed for NIHSS and the combination of NIHSS and selected serum biomarkers levels. RESULTS One thousand three hundred eight suspected strokes were enrolled for a 17-month period. LVO was not assessed in 131 patients. One thousand one hundred seventy-seven patients were selected for analysis (mean age 69.3 years, 56% men, median baseline NIHSS of 6, and median time to blood collection 2.5 hours). LVO was detected in 262 patients. LVO patients were older, had higher baseline NIHSS, history of atrial fibrillation, and lower time from stroke onset to admission. After logistic regression analysis, D-dimer remained an independent predictor of LVO (odds ratio, 1.59 [1.31-1.92]). Specificity and positive predictive value to exclude or detect LVO were higher when using combined D-dimer levels and NIHSS score assessment rather than NIHSS alone. CONCLUSIONS Early D-dimer levels are an independent predictor of LVO and may be useful to better optimize prehospital patient transport to the appropriate stroke center.

Abstract
Background D‐dimer is involved in poor outcomes of stroke as a coagulation biomarker. We aimed to investigate the associations of the level and increase in D‐dimer between baseline and 90 days with all‐cause death or poor functional outcome in patients after ischemic stroke or transient ischemic attack. Methods and Results We collected data from the CNSRIII (Third China National Stroke Registry) study. The present substudy included 10 518 patients within 7 days (baseline) of ischemic stroke or transient ischemic attack and 6268 patients at 90 days. Poor functional outcome at 1 year was assessed on the basis of the modified Rankin Scale (≥3). Multivariable Cox regression or logistic regression was used to assess the association of D‐dimer levels with all‐cause death or poor functional outcome. D‐dimer levels at 90 days were lower than those at baseline (1.4 µg/mL versus 1.7 µg/mL; P<0.001). Higher baseline D‐dimer level was associated with all‐cause death (adjusted hazard ratio [HR], 1.77; 95% CI, 1.25–2.52; P=0.001) and poor functional outcome (adjusted odds ratio [OR], 1.49; 95% CI, 1.23–1.80; P<0.001) during 1‐year follow‐up. Higher D‐dimer level at 90 days was also associated with poor outcomes independently. Furthermore, an increase in D‐dimer levels between baseline and 90 days was associated with all‐cause death (since 90 days to 1 year after index event) (adjusted HR, 1.99; 95% CI, 1.12–3.53; P=0.019) but not with poor functional outcome (adjusted OR, 1.08; 95% CI, 0.82–1.41). Conclusions Our study shows that high level and an increase in D‐dimer between baseline and 90 days are associated with poor outcomes in patients after ischemic stroke or transient ischemic attack.

Abstract
INTRODUCTION We aimed to evaluate the predictive value of sex hormone levels on 3-month functional outcomes after acute ischemic stroke (AIS) in males. MATERIALS AND METHODS A total of 110 male AIS patients were included in this prospective study. Serum levels of testosterone and estradiol were measured at admission. The National Institutes of Health Stroke Scale (NIHSS) and the modified Rankin Scale (mRS) were measured at admission and after 3 months. A mRS score ≥3 was considered as a poor functional outcome. RESULTS The median age of the 110 subjects was 62.0 [23.3] years (range 35-93 years). Univariate logistic regression revealed that bioavailable testosterone, free testosterone, age, NIHSS at admission, mRS at admission, and prior ischemic stroke were associated with a poor functional outcome (mRS score ≥3) at 3 months. In multivariate analysis, only age, NIHSS at admission, and mRS at admission were independent predictors. CONCLUSIONS After controlling the covariates, bioavailable and free testosterone levels are not associated with the 3-month mRS in male patients with AIS. Age, NIHSS at admission, and mRS at admission are robust predictors for the functional outcomes.

Abstract
BACKGROUND Previous studies indicate that the levels of d-dimer and blood lipids at admission affect the prognosis of patients with acute ischemic stroke (AIS), however, whether there is a dose-response effect of d-dimer on prognosis, or a combined effect of d-dimer with blood lipids on prognosis, remains unclear. METHODS In this prospective cohort study, 1485 AIS patients were recruited. All participants received medical care within 24 h from the onset of stroke, the level of d-dimer and related indices were measured at admission. Then, National Institutes of Health Stroke Scale (NIHSS) scores were obtained at the time of admission and discharge. Afterwards, 3-, 6- and 12- month follow-up was conducted to obtain Modified Rankin Scale (mRS) scores after discharge. RESULTS A high level of d-dimer at admission was associated with clinical outcome of AIS, after adjusting other relevant factors, with an OR (95%CI) of 2.934(1.914-4.500), 3.052(1.912-4.872), 3.306(1.873-5.835) and 2.828(1.447-5.527) at discharge, at 3-, 6-, and 12-month follow-up respectively, a dose-response effect was observed during follow-up (p = 0.00001). When d-dimer was combined with total cholesterol (TC), after adjusting other relevant factors, OR (95%CI) was 2.799 (1.708-4.587), 2.473 (1.475-4.147), 2.381 (1.333-4.255), and 2.619 (1.320-5.193), at each follow-up period respectively. When combined with low-density lipoprotein (LDL), OR (95%CI) was 3.105 (1.729-5.577), 3.280 (1.762-6.104), 2.744 (1.344-5.604), and 4.400 (1.883-10.282), respectively. CONCLUSIONS D-dimer levels at admission may predict the prognosis of AIS patients in a dose-response pattern. Moreover, d-dimer combined with TC or LDL predict prognosis of AIS.

Abstract
OBJECTIVE We proposed the concept of the cerebral infarction coefficient, which is cerebral infarction volume/brain volume. This study aimed to evaluate the prognostic value of the cerebral infarction coefficient in patients with massive cerebral infarction (MCI). METHODS According to the modified Rankin score, 71 patients with acute MCI were divided into good prognosis and poor prognosis groups. Clinical and imaging data of the two groups were collected and univariate analysis was carried out. If there were significant differences in the data between the two groups, binary logistic regression analysis was performed. RESULTS The poor prognosis group had a significantly higher cerebral infarction volume, cerebral infarction coefficient, and D-dimer levels, older age, the highest body temperature, a higher rate of a history of atrial fibrillation, and a lower rate of a history of hypertension compared with the good prognosis group (all P < 0.05). Binary logistic regression analysis showed that the cerebral infarction coefficient was an independent risk factor for a poor prognosis of patients with MCI (P < 0.05, 95 % confidence interval, 2.091, 42.562), and the odds ratio was 8.506. The area under the receiver operating characteristic curve for the cerebral infarction coefficient was 0.753. When the cut-off value was 7.8 %, the sensitivity of predicting a poor prognosis of patients with MCI was 92.5 %. CONCLUSION The cerebral infarction coefficient may have predictive value in determining the prognosis of patients with MCI.

Abstract
INTRODUCTION AND OBJECTIVE At present, there is no hematology marker with high specificity to the diagnosis and differential diagnosis of acute ischemic stroke (AIS). How to use the existing test items to improve the diagnosis efficiency worthy of discussion. D-Dimer (DD) and fibrinogen (FIB) were the common indicators in thrombotic diseases, but D-dimer to fibrinogen ratio (D/F) in AIS has not been used in clinical practice. In this work, we focus on the evaluation of D/F. METHODS 90 AIS patients were selected as the observation group and 65 other patients without coagulation function disorder as the control group. Meanwhile, a total of 33 patients with other diseases with impaired consciousness in the same period were collected. Based on the AIS patients with or without consciousness disorder divided it into consciousness disorder group and unconsciousness disorder group. Then based on the patients with or without consciousness disorder divided it into other diseases with unconsciousness disorder group and Other diseases with lacunar cerebral infarction (LCI)and disturbance of consciousness group. then compare the differences of plasma DD, FIB and D/F between groups. RESULTS All plasma DD, FIB and D/F ratio in AIS patients were significantly higher than in other disease group (P = 0.000, P = 0.001, P = 0.000), but DD, D/F in disorders of consciousness group was significantly higher than in unconsciousness disorders group (P = 0.007, P = 0.005). The DD of the AIS with consciousness disorder group were significantly higher than that of the other disease with consciousness disorder group (P = 0.042), and the DD, D/F ratio of Other diseases with lacunar cerebral infarction and disturbance of consciousness group were significantly higher than one(P = 0.000, P = 0.003). All others are undifferentiated. CONCLUSIONS When DD, D/F ratio is high, other diseases caused by consciousness disorders are likely to be combined with infarcts, which can be used for the diagnosis and differential diagnosis of patients with different types of consciousness disorders, especially hospitalized patients.

Abstract
Background Ischemic stroke is one of the most prominent and serious neurological complications of infective endocarditis (IE). Our study was designed to evaluate the predictive value of higher level of plasma D‐dimer on admission for the development of ischemic stroke in patients with IE. Methods In this prospective study, a total of 173 consecutive patients with IE were recruited from January 2016 to December 2018. Plasma D‐dimer and other clinical indexes of IE patients were measured after admission. The number of patients who developed ischemic stroke during 6‐month follow‐up was recorded, as well as the occurrence time of ischemic stroke. Results Ischemic stroke was observed in 38 (22%) patients during 6‐month follow‐up since definite diagnosis of IE. Patients with ischemic stroke had significantly higher levels of plasma D‐dimer than those of patients without stroke (4982 vs 2205 μg/L, P < .001). In addition, Staphylococcus aureus infection (HR: 1.96, 95% CI: 1.51‐2.42), mitral valve vegetation (HR: 1.52, 95% CI: 1.32‐1.75), and higher levels of on‐admission plasma D‐dimer (HR: 1.35, 95% CI: 1.27‐1.43) were significantly associated with ischemic stroke. Moreover, D‐dimer levels ≥3393 μg/L served as a strong predictor for ischemic stroke in patients with IE, and the sensitivity and specificity were 78% and 83%, respectively. Conclusion Our study suggested that higher level of D‐dimer on admission was an independent predictor for ischemic stroke in patients with IE. These patients may require special attention, in particular within the first trimester after IE diagnosis.

Abstract
Supplemental Digital Content is available in the text. Objectives— The prediction of patients at risk for poor clinical outcome after acute ischemic stroke remains challenging. An imbalance of coagulation factors may play an important role in progression and prognosis of these patients. In this systematic review, we assessed the current literature on hemostasis biomarkers and the association with poor clinical outcome in acute ischemic stroke. Approach and Results— A systematic search of Embase, Medline, Cochrane Library, Web of Science, and Google Scholar was performed on studies reporting on hemostasis biomarkers and clinical outcome after acute ischemic stroke. Studies were considered eligible if blood samples were collected within 72 hours after symptom onset. Additionally, clinical outcome should be assessed using a disability score (Barthel Index or modified Rankin scale). Methodological quality of included studies was assessed with an adapted version of the Quality Assessment of Diagnostic Accuracy Studies questionnaire. A total of 80 articles were read full text, and 41 studies were considered eligible for inclusion, reporting on 37 different hemostasis biomarkers. No single biomarker appeared to be effective in predicting poor clinical outcome in acute ischemic stroke patients. Conclusions— Based on current literature, no clear recommendations can be provided on which hemostasis biomarkers are a predictor of clinical outcome after acute ischemic stroke. However, some biomarkers show promising results and need to be further investigated and validated in large populations with clear defined study designs.

Abstract
Objective To investigate the predictive value of clinical variables on the poor prognosis at 90-day follow-up from acute stroke onset, and compare the diagnostic performance between back propagation artificial neural networks (BP ANNs) and Logistic regression (LR) models in predicting the prognosis. Methods We studied the association between clinical variables and the functional recovery of 435 acute ischemic stroke patients. The patients were divided into 2 groups according to modified Rankin Scale scores evaluated on the 90th day after stroke onset. Both BP ANNs and LR models were established for predicting the poor outcome and their diagnostic performance were compared by receiver operating curve. Results Age, free fatty acid, homocysteine and alkaline phosphatase were closely related with the poor outcome in acute ischemic stroke patients and finally enrolled in models. The accuracy, sensitivity and specificity of BP ANNs were 80.15%, 75.64% and 82.07% respectively. For the LR model, the accuracy, sensitivity and specificity was 70.61%, 88.46% and 63.04% respectively. The area under the ROC curve of the BP ANNs and LR model was 0.881and 0.809. Conclusions Both BP ANNs and LR model were promising for the prediction of poor outcome by combining age, free fatty acid, homocysteine and alkaline phosphatase. However, BP ANNs model showed better performance than LR model in predicting the prognosis.

Abstract
OBJECT The purpose of our study was to assess the prognostic role of early D-dimer level in patients with acute ischemic stroke (AIS). METHODS The included patients' D-dimer levels have to be tested within 24 hours from stroke onset. Poor functional outcome was defined as modified Rankin Scale (mRS) ≥3. The endpoints included recurrence on 5-day diffusion-weighted imaging, 30-day mRS ≥3, 30-day mortality and 90-day mRS ≥3. Regarding to each endpoint, odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the prognostic role of D-dimer in patients with AIS. RESULTS A total of 2,479 patients were included. The results showed that elevated D-dimer levels were associated with recurrence on 5-day diffusion-weighted imaging (OR = 2.28, 95% CI = 1.32-3.95), 30-day mRS≥3 (OR = 1.59, 95% CI = 1.37-1.85), 30-day mortality (OR = 1.92, 95% CI = 1.27-2.90) and 90-day mRS≥3 (OR = 1.61, 95% CI = 1.05-2.46). CONCLUSIONS In conclusion, for patients with AIS, higher D-dimer level within 24 hours from stroke onset was associated with recurrence on 5-day diffusion-weighted imaging, mortality at 30 days, and poor functional outcome at both 30 days and 90 days. However, more studies are warranted to clarify this issue.

Abstract
Background: The aim of our meta-analysis was to evaluate the association between plasma d-dimer and intracerebral hemorrhage (ICH). Methods: Embase, Pubmed, and Web of Science were searched up to the date of March 19th, 2018, and manual searching was used to extract additional articles. Standard mean difference (SMD) with 95% confidence intervals (CI) was calculated to evaluate d-dimer levels. Results: Thirteen studies including 891 ICH patients and 1,573 healthy controls were included. Our results revealed that higher levels of d-dimer were displayed in ICH patients than those in healthy controls (95% CI= 0.98–2.00, p< 0.001). Subgroup analysis based on continent of Asia and Europe, sample size, as well as age in relation to d-dimer levels between ICH patients and healthy controls did not change the initial observation; whereas no differences of d-dimer levels were found between ICH and controls in America. Conclusions: This meta-analysis revealed that high level of d-dimer is associated with the risk of ICH. Plasma d-dimer is suggested to be a potential biomarker for patients with ICH in Asia and Europe rather than in America. There were no impact of sample size-related differences and age-related diversities on the risk of ICH with respect to d-dimer levels.

Abstract
BACKGROUND Stroke is one of the leading causes of disability worldwide. Early prediction of poststroke disability using clinical models is of great interest, especially in the rehabilitation field. Although some biomarkers and neuroimaging techniques have shown potential predictive value, there are still insufficient data to support their clinical utility in predicting poststroke functional recovery. We aimed to assess the value of serum biomarkers (C-reactive protein [CRP], D-dimer, fibrinogen, and S100β protein) in predicting medium-term (12 weeks) functional outcome in patients with acute ischemic stroke. METHODS This is an observational, prospective study in a sample of patients hospitalized for ischemic stroke (N = 131). Peripheral blood levels of biomarkers of interest were determined at admission (CRP, D-dimer, and fibrinogen) or at 48 hours poststroke (S100β protein). Functional status was accessed at 48 hours and 12 weeks poststroke using the modified Rankin Scale (mRS). RESULTS S100β protein levels measured at 48 hours were significantly associated with mRS scores at 12 weeks (odds ratio = 1.005, 95% confidence interval [CI] [1.005-1.007]; P <.001). This association was not seen for the remaining biomarkers of interest. The S100β cutoff for poor functionality at 12 weeks was 140.5 ng/L or more (sensibility 83.8%; specificity 71.4%; area under the curve = .80, 95% CI [.722, .879]). CONCLUSIONS S100β levels in peripheral blood at 48 hours poststroke reflect acute stroke severity and predict functional outcome at 12 weeks with a cutoff value of 140.5 ng/dL. The value of S100β as predictor of functional recovery after stroke should be emphasized in further clinical research and clinical practice.

Abstract
The aim of this study was to systematically evaluate the association between D-dimer level and the risk of stroke through performing a meta-analysis. PubMed, Web of Science, EMBASE and Cochrane Library were searched for potentially eligible literature. Prospective observational studies or case-control studies were included. The study characteristics and relevant data were extracted. Hazard ratios (HRs) or odds ratios (ORs) with 95% confidence intervals (CIs) were pooled to estimate the association between D-dimer level and the risk of stroke. Seven prospective studies with 22,207 patients and three case-control studies with 2,248 patients were included. For the prospective studies, the pooled HRs of higher D-dimer level for all types of stroke, ischemic stroke and hemorrhagic stroke were 1.55 (95% CI, 1.28- 1.87), 1.62 (95% CI, 1.18-2.22) and 1.30 (95% CI, 0.63-2.68), respectively. The pooled HRs per SD increase in log D-dimer for all types of stroke, ischemic stroke and hemorrhagic stroke were 1.16 (95% CI, 1.06-1.26), 1.11 (95% CI, 1.03-1.21) and 1.11 (95% CI, 0.95-1.30), respectively. For the case-control studies, the pooled OR of higher D-dimer level for acute ischemic stroke was 2.06 (95% CI, 1.08-3.96). No significant publication bias was found in the meta-analysis. In conclusion, our results suggested that higher D-dimer level was associated with higher risk of stroke, especially ischemic stroke.

Abstract
After an acute ischemic stroke (AIS), inflammatory processes are able to concomitantly induce both beneficial and detrimental effects. In this narrative review, we updated evidence on the inflammatory pathways and mediators that are investigated as promising therapeutic targets. We searched for papers on PubMed and MEDLINE up to August 2016. The terms searched alone or in combination were: ischemic stroke, inflammation, oxidative stress, ischemia reperfusion, innate immunity, adaptive immunity, autoimmunity. Inflammation in AIS is characterized by a storm of cytokines, chemokines, and Damage-Associated Molecular Patterns (DAMPs) released by several cells contributing to exacerbate the tissue injury both in the acute and reparative phases. Interestingly, many biomarkers have been studied, but none of these reflected the complexity of systemic immune response. Reperfusion therapies showed a good efficacy in the recovery after an AIS. New therapies appear promising both in pre-clinical and clinical studies, but still need more detailed studies to be translated in the ordinary clinical practice. In spite of clinical progresses, no beneficial long-term interventions targeting inflammation are currently available. Our knowledge about cells, biomarkers, and inflammatory markers is growing and is hoped to better evaluate the impact of new treatments, such as monoclonal antibodies and cell-based therapies.

MicroRNA-146a down-regulation correlates with neuroprotection and targets pro-apoptotic genes in cerebral ischemic injury in vitro. Brain Res 2016; 1648:136-143. [PMID: 27449900 DOI: 10.1016/j.brainres.2016.07.034] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2016] [Revised: 07/11/2016] [Accepted: 07/19/2016] [Indexed: 12/25/2022]
Abstract
MicroRNAs (miRNAs) are short, non-coding RNAs that negatively regulate target gene expression, and play an important role in cerebral ischemic injury. MiR-146a has been reported to be highly related to cell invasion, metastasis, immunity, inflammation and apoptosis. Previous studies have indicated that miR-146a can either inhibit or promote apoptosis through different pathophysiological processes. In our previous study, miR-146a in the blood was down-regulated during acute ischemic stroke. However, the connection between miR-146a and acute cerebral ischemic injury and the mechanism underlying the connection remain unclear. Here, we aimed to investigate the role of miR-146a and its possible target genes in human SK-N-SH cells subjected to 16h of oxygen-glucose deprivation and 12h of reperfusion (OGD/R) injury. Cells were transfected with miR-146a mimic or inhibitor to alter the expression of miR-146a. MiR-146a in the SK-N-SH cells was down-regulated after OGD/R injury. Moreover, bioinformatics analysis and dual luciferase assays demonstrated that miR-146a directly recognized the 3'-UTR of the pro-apoptotic genes, Caspase7 and Bcl-2-associated transcription factor 1 (Bclaf1). Furthermore, miR-146a over-expression effectively decreased the mRNA and protein expression of Caspase7 and Bclaf1, and aggravated OGD/R-induced cell apoptosis; in contrast, miR-146a down-regulation was neuroprotective. In conclusion, our study revealed that miR-146a contributes to OGD/R injury in vitro, while negatively regulating the pro-apoptotic genes, Caspase7 and Bclaf1. This special mechanism provides new insight into miRNA regulatory networks. In addition, miR-146a may offer a potential therapeutic approach to cerebral ischemic injury.
