Small dense low-density lipoprotein (sdLDL) is an established risk factor in ischemic heart disease. However, its clinical significance in acute ischemic stroke (AIS) is uncertain. This study evaluates the prognostic value of the presence of sdLDL in patients with AIS by determining whether it contributes to clinical outcome or not. We studied 530 consecutive patients admitted within the first 48 hours after onset of ischemic stroke and 50 corresponding controls. Serum lipid parameters were measured on admission by standard laboratory methods. The percentage of AIS patients with sdLDL was significantly higher than the one of matched controls with sdLDL. Concerning comparisons between AIS patients with or without sdLDL, the percentages of males and patients with histories of smoking, hypertension, and cardiovascular disease were significantly higher in AIS patients with sdLDL. Concerning the grade of severity, modified Rankin Scale (mRS) on discharge was significantly higher in AIS patients with sdLDL. On logistic regression analysis, age (OR=2.29, P3). Our study showed that the presence of sdLDL might be independently associated with a poor prognosis after AIS.

<b><i>Introduction:</i></b> The delipid extracorporeal lipoprotein filter from plasma (DELP) has been approved for the treatment of acute ischemic stroke (AIS) by the China Food and Drug Administration, but its effectiveness and mechanism are not yet fully determined. The purpose of this study was to evaluate the effect of DELP treatment on AIS patients after intravenous thrombolysis. <b><i>Methods:</i></b> A retrospective study was performed on AIS patients with no improvement within 24 h after intravenous thrombolysis who were subsequently treated with or without DELP. Primary outcome was the proportion with a modified Rankin scale (mRS) of 0–1 at 90 days. Secondary outcomes were changes in National Institute of Health Stroke Scale (NIHSS) score from 24 h to 14 days after thrombolysis, and the rate of improvement in stroke-associated pneumonia (SAP). The main safety outcomes were the rates of symptomatic intracranial hemorrhage and mortality. To investigate its mechanisms, serum biomarkers were measured before and after DELP. <b><i>Results:</i></b> A total of 252 patients were recruited, 63 in the DELP group and 189 matched patients in the NO DELP group. Compared with the NO DELP group, the DELP group showed an increase in the proportion of mRS 0–1 at 90 days (<i>p</i> = 0.042). More decrease in NIHSS from 24 h to 14 days (<i>p</i> = 0.024), a higher rate of improvement in SAP (<i>p</i> = 0.022), and lower mortality (<i>p</i> = 0.040) were shown in DELP group. Furthermore, DELP decreased levels of interleukin (IL)-1β, E-selectin, malondialdehyde, matrix metalloprotein 9, total cholesterol, low-density lipoprotein, and fibrinogen, and increased superoxide dismutase (<i>p</i>&#x3c; 0.05). <b><i>Conclusions:</i></b> DELP following intravenous thrombolysis should be safe, and is associated with neurological function improvement, possibly through multiple neuroprotective mechanisms. Prospective trials are needed.

Objectives: The purpose of this study was to illustrate a new low-density lipoprotein cholesterol (LDL-C) adsorption system, Delipid Extracorporeal Lipoprotein filter from Plasma (DELP) system, and evaluate its safety and efficacy in acute ischemic stroke patients. Methods: This is an observational study of 22 acute ischemic stroke patients who underwent DELP treatment from March to August 2019. The DELP system was composed of a plasma filter JX-DELP, a COM.TEC cell separator and Tubing P1R Plasma Treatment Set. Clinical data and laboratory results including plasma lipids and some safety parameters before and after the apheresis were collected and analyzed. Results: The present study included 22 patients (15 males, 7 females, 59.95±13.71 years). The mean LDL-C was significantly reduced from 3.36±0.64 mmol/L to 2.30±0.53 mmol/L (31.5%, p <0.001, n=22) during a single DELP treatment, and from 3.59±0.48 mmol/L to 1.85±0.50 mmol/L (48.2%, p <0.001, n=13) after two apheresis, respectively. No clinically relevant changes were observed in hematologic safety parameters during DELP treatments. Conclusions: We concluded that the new LDL-C adsorption system is a promising method for timely and controllable LDL-C administration in acute ischemic stroke patients in view of its high efficacy, simple operation, and safety.

Background: To assess the role of risk factors of metabolic syndrome on blood viscosity and the prognosis of acute ischemic stroke in Indonesia based on the National Institute of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS). Methods: This study included 135 patients with acute ischemic stroke. Patients underwent measurements of viscosity and risk factor assessment. Analysis was performed to assess the role of these risk factors for blood viscosity and outcomes of acute ischemic stroke with NIHSS and mRS as indicators. NIHSS was assessed at <3 days after onset and 7 days after onset, while mRS was assessed 1 month post treatment. Bivariate analysis was performed using chi-square test, and variables with p < 0.25 were further analyzed in multivariate analysis using logistic regression. Results: Factors affecting blood viscosity are fibrinogen, low-density lipoprotein (LDL), and hematocrit. Factors affecting NIHSS and mRS are fibrinogen and LDL. Conclusion: Fibrinogen and LDL affect the viscosity of blood and outcomes in acute ischemic stroke patients, so it is necessary to treat in the primary and secondary prevention of ischemic stroke.

Background and Purpose: Hemorrhagic transformation (HT) is a potentially serious complication in patients with acute ischemic stroke (AIS). Whether the ratio of low-density lipoprotein cholesterol to high-density lipoprotein cholesterol (LDL-C/HDL-C) is associated with HT remains unclear. Methods: Ischemic stroke patients within 7 days of stroke onset from January 2016 to November 2017 were included in this study. Lipid profiles were measured within 24h after admission. HT was determined by a second computed tomography or magnetic resonance imaging within 7 days after admission. Univariate and multivariate logistic regression analysis was used to assess the association between LDL-C/HDL-C and HT. Results: We enrolled 1239 patients with AIS (788 males; mean age, 64 ± 15 years), of whom 129 (10.4%) developed HT. LDL-C/HDL-C was significantly lower on admission in patients with HT than those without HT (2.00 ± 0.89 vs. 2.25 ± 1.02, P=0.009). The unadjusted odds ratio (OR) of low LDL-C/HDL-C for HT was 2.07 (95% confidence interval [CI] 1.42-3.01, P<0.001). After adjustment for possible confounders, lower LDL-C/HDL-C (≤1.52) was significantly associated with HT (OR 1.53, 95% CI: 1.02-2.31, P=0.046). Similar results were observed between lower LDL-C (≤ 4 mmol/L) and HT (OR 4.17, 95% CI: 1.25-13.90, P=0.02). However, no significant association was found between HT and high HDL-C, low triglycerides or low total cholesterol. Conclusion: Lower LDL-C/HDL-C and LDL-C were significantly associated with increased risk of HT after AIS. Further investigations are warranted to confirm these findings and then optimize lipid management in stroke patients with lower LDL/HDL-C or LDL-C.

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.

Background and Purpose: Guideline adherence for acute ischemic stroke (AIS) management is often suboptimal, particularly in thrombolytic therapy and anticoagulants for atrial fibrillation. We sought to achieve quality improvement of AIS patients via a collaborative learning model, the Breakthrough Series (BTS)-Stroke, in a nationwide, multi-center activity in Taiwan. Methods: A BTS Collaborative, a short-term learning system for a large number of multidisciplinary teams from hospitals, was applied to enhance AIS care quality. There were 24 teaching and community hospitals participating in and submitting data for this stroke quality improvement campaign from August 2010 to June 2011. The Get With The Guideline (GWTG)-Stroke measures were adopted to evaluate the performance and outcome of the AIS patients. The results of this study were compared to those of the previous Taiwan Stroke Registry (TSR, 22642 AIS patients from 39 hospitals, 2006-08). Results: Data from 24 hospitals with 13181 AIS patients during a 1-year period were analyzed. The BTS-Stroke (2010-11) had better performance as compared to the TSR (2006-08): intravenous thrombolysis frequency for all AIS patients (4.1% vs 1.5%), symptomatic hemorrhage after intravenous thrombolysis (6.0% vs 8.2%), early antithrombotics (96.6% vs 94.1%), anticoagulation for atrial fibrillation (57.1% vs 28.3%), lipid lowering drugs for low-density lipoprotein >100 mg/dL (63.4% vs 38.7%), antithrombotics at discharge (94.0% vs 85.5%), and one-month mortality (3.5% vs 4.0%). Temporal improvement was noted in 7 of 14 performance measures when the fourth BTS-Stroke quarter compared with the first quarter: intravenous thrombolysis frequency for all AIS patients (4.1% vs 3.7%), symptomatic hemorrhage after intravenous thrombolysis (3.4% vs 5.5%), lipid lowering drugs for low-density lipoprotein >100 mg/dL (67.3% vs 60.5%), antithrombotics at discharge (95.5% vs 91.4%), dysphagia screening (81.9% vs 63.4%), early rehabilitation (71.7% vs 63.6%), stroke education before discharge (95.6% vs 83.4%). Conclusions: A BTS collaborative learning and campaign model can improve the guideline adherence of stroke. The GWTG-Stroke can be successfully applied to other countries outside the United States.

Abstract Background Atrial fibrillation (AF) is a common cause of cerebral infarction, which could lead to endothelial dysfunction, increased reactive oxygen species (ROS) and oxidized low density lipoprotein (Ox-LDL).AF is associated with higher mortality and more severe neurologic disability. Statins may exert neuroprotective effects that are independent of LDL-C lowering. The purpose of our study was to investigate whether prestroke statins use could reduce plasma Ox-LDL levels and improve clinical outcomes in patients with AF-related acute ischemic stroke (AIS). Methods This was a multicenter prospective study that involved four medical centers, 242 AIS patients with AF were identified, who underwent a comprehensive clinical investigation and a 72 h-Holter electrocardiogram monitoring. All patients were divided into two groups: prestroke statins use and no prestroke statins use groups, who were followed up for 3 months. Plasma Ox-LDL levels were measured using enzyme-linked immunosorbent assay (ELISA) on admission and at 3 months. The outcome was death, major disability (modified Rankin Scale score ≥ 3), and composite outcome (death/major disability) at 3 months after AIS. Results One hundred thirty-six patients were in no prestroke statins use group, and 106 in prestroke statins use group. Plasma Ox-LDL levels were significantly lower in prestroke statins use than in no prestroke statins use on admission and at 3 months (P < 0.001). Plasma Ox-LDL levels on admission were associated with 3-month mortality [adjusted odds ratio (OR), 1.05; 95% confidence interval (CI), 0.99–1.12; P = 0.047]. In fully adjusted models, prestroke statins use was associated with reduced 3-month mortality [adjusted OR, 0.38; 95% CI, 0.16–0.91; P = 0.031)], major disability (adjusted OR, 0.38; 95% CI, 0.15–0.99; P = 0.047), and composite outcome (adjusted OR, 0.31; 95% CI, 0.17–0.74; P = 0.009). Conclusions Prestroke statins use can reduce plasma Ox-LDL levels and improve clinical outcomes in patients with AF-related AIS.

     THE EFFECT OF INTERLEUKIN-6 AND NEURON SPECIFIC ENOLASE LEVEL ON ACUTE ISCHEMIC STROKE OUTCOME WITH PACS AND LACS SUBTYPEABSTRACTIntroduction: Brain blood flow disruption  in ischemic stroke will trigger  cells damage  cascade  and  caused infarction. Interleukin-6 (IL-6) and neuron specific enolase (NSE) are brain cells damage marker that can be markers of acute ischemic stroke outcome.Aim: To investigate the effect of IL-6 and NSE levels on acute ischemic stroke outcome and its interacting factors.Methods: An observational cohort study on ischemic stroke patients with onset ≤3 days in several hospitals in Jakarta and Depok in 2014. Medical history and physical examination were carried out as well as laboratory parameters; hematocrit, fibrinogen, low density lipoprotein (LDL), high density lipoprotein (HDL), triglyceride, IL-6, and NSE. The National Institute of Health Stroke Scale (NIHSS) were assessed ≤72 hours of onset and 7 days along with Modified Rankin Scale (mRS) at 1 month of onset. Bivariate and multivariate logistic regression were done to investigate the association of IL-6 and NSE with stroke outcome and other factors.Results: One-hundred thirty-five subjects were included, mostly male (62%), with age mean 59,4±10,7 years and subtype PACS (76%). Interleukin-6 and NSE level were elevated in 61,5% and 21,5% subjects. Interleukin-6 and fibrinogen influenced the mRS, while diabetes and fibrinogen influenced the NIHSS. NSE serum didn’t show any association with mRS nor NIHSS, but influenced by dyslipidemia.Discussion: There was a tendency of worse outcome on high IL-6 level patients, although by multivariate analysis IL-2 alone was not sufficient enough as prognostic marker in acute ischemic stroke outcome. Neuron specific enolase serum didn’t show any association with acute stroke outcome due to also influenced by sex, smoking, and fibrinogen levels.Keywords: Acute ischemic stroke, IL-6, NSE, outcomeABSTRAKPendahuluan: Gangguan aliran darah otak pada stroke iskemik akut akan memicu kaskade kerusakan sel otak yang menyebabkan infark dan inflamasi. Interleukin-6 (IL-6) dan neuron specific enolase (NSE) merupakan penanda kerusakan sel otak yang dapat menjadi penanda luaran stroke iskemik akut.Tujuan: Mengetahui pengaruh kadar IL-6 dan NSE pada luaran stroke iskemik akut serta faktor-faktor yang memengaruhinya.Metode: Penelitian kohort observasional terhadap pasien stroke iskemik akut dengan awitan ≤3 hari yang dirawat di beberapa RS di Jakarta dan Depok pada tahun 2014. Dilakukan anamnesis dan pemeriksaan fisik serta pemeriksaan hematokrit, fibrinogen, low density lipoprotein (LDL), high density lipoprotein  (HDL), trigliserida, IL-6, dan NSE serum. Dilakukan pemeriksaan National Institute of Health Stroke Scale (NIHSS) awal awitan ≤72 jam dan 7 hari serta modified rankin scale (mRS) pada 1 bulan. Analisis statistik bivariat dan regresi logistik multivariat dilakukan untuk mengetahui hubungan kadar IL-6 dan NSE dengan luaran stroke serta hubungannya terhadap faktor-faktor lainnya.Hasil: Didapatkan 135 subjek yang mayoritas laki-laki (62%) dengan rerata usia 59,4±10,7 tahun dan subtipe PACS (76%). Peningkatan kadar IL-6 dan NSE ditemukan pada 61,5% dan 21,5% subjek. Luaran berdasarkan skor mRS dipengaruhi oleh kadar IL-6 dan fibrinogen, sedangkan  berdasarkan NIHSS dipengaruhi oleh diabetes melitus dan fibrinogen. Kadar NSE tidak berhubungan dengan mRS dan NIHSS, namun dipengaruhi oleh status dislipidemia.Diskusi: Terdapat kecenderungan luaran buruk pada kadar IL-6 tinggi, namun dengan analisis multivariat IL-6 belum bisa menjadi penanda prognosis luaran stroke iskemik akut. Kadar NSE serum tidak berperan terhadap luaran stroke iskemik akut, oleh karena juga dipengaruhi oleh jenis kelamin, merokok, dan kadar fibrinogen.Kata kunci: Stroke iskemik akut, IL-6, neuron specirefic enolase, luaran
