    Acute Stroke Management in Türkiye: Intravenous Tissue Plasminogen Activator and Thrombectomy NöroTek: Türkiye Neurology Single Day Study
    (2023) Arlier, Zulfikar; Can, Ufuk
    Objective: To reveal the profile and practice in patients with acute stroke who received intravenous tissue plasminogen activator (IV tPA) and/or neurointerventional therapy in Turkiye. Materials and Methods: On World Stroke Awareness Day, May 10, 2018, 1,790 patients hospitalized in 87 neurology units spread over 30 health regions were evaluated retrospectively and prospectively. Results: Intravenous tPA was administered to 12% of 859 cases of acute ischemic stroke in 45 units participating in the study. In the same period, 8.3% of the cases received neurointerventional treatment. The rate of good prognosis [modified Rankin score (mRS) 0-2] at discharge was 46% in 83 patients who received only IV tPA [age: 67 +/- 12 years; National Institutes of Health Stroke Scale (NIHSS): 12 +/- 6; hospital stay, 24 +/- 29 days]; 35% in 51 patients who underwent thrombectomy (MT) alone (age: 64 +/- 13 years; NIHSS: 14.1 +/- 6.5; length of hospital stay, 33 +/- 31 days), 19% in those who received combined treatment (age: 66 +/- 14 years; NIHSS: 15.6 +/- 5.4; length of hospital stay, 26 +/- 35 days), and 56% of 695 patients who did not receive treatment for revascularization (age: 70 +/- 13 years; NIHSS: 7.6 +/- 7.2; length of hospital stay, 21 +/- 28 days). The symptom-to-door time was 87 +/- 53 minutes in the IV treatment group and 200 +/- 26 minutes in the neurointerventional group. The average door-to-needle time was 66 +/- 49 minutes in the IV tPA group. In the neurothrombectomy group, the door-to-groin time was 103 +/- 90 minutes, and the TICI 2b-3 rate was 70.3%. In 103 patients who received IV tPA, the discharge mRS 0-2 was 41%, while the rate of mRS 0-1 was 28%. In 71 patients who underwent neurothrombectomy, the mRS 0-2 was 31% and mRS 0-1 was 18%. The door-to-groin time was approximately 30 minutes longer if IV tPA was received (125 +/- 107 and 95 +/- 83 minutes, respectively). Symptomatic bleeding rates were 4.8% in IV recipients, 17.6% among those who received only MT, and 15% in combined therapy. Globally, the hemorrhage rate was 6.8% in patients receiving IV tPA and 16.9% in MT. Conclusion: IV thrombolytic and neurointerventional treatment applications in acute ischemic stroke in Turkiye can provide the anticipated results. Heterogeneity has begun to be reduced in our country with the dissemination of the system indicated by the "Directive on Health Services to be Provided to Patients with Acute Stroke."

    Neutrophil to lymphocyte ratio, stroke severity and short term clinical outcomes in acute ischemic stroke
    (2021) Iyigundogdu, Ilkin; Derle, Eda; Kibaroglu, Seda; Can, Ufuk; 0000-0001-7860-040X; 0000-0002-3964-268X; AAJ-2053-2021; AAJ-2956-2021
    Background: Neutrophil to lymphocyte ratio is an easily evaluated systemic inflammation indicator. However, there are limited reports on neutrophil to lymphocyte ratio and functional outcome in ischemic stroke. In this study, we aimed to evaluate the association of neutrophil to lymphocyte ratio and stroke severity, short term functional outcomes and mortality in patients with acute ischemic stroke. Methods: The clinical data of patients who were > 18 age-old and hospitalized with acute ischemic stroke in Baskent University Hospital, Ankara, Turkey between January 2018 and May 2019 were studied retrospectively. Neutrophil to lymphocyte ratio were measured. The neutrophil to lymphocyte ratio and National Institute of Health Stroke Scale (NIHSS) score at admission, mortality during hospitalization and Modified Rankin Scale (mRS) score at discharge of the patients with acute ischemic stroke were correlated. Results: Among the acute ischemic stroke patients due to the exclusion criteria, the data of 134 patients were evaluated. Median age of the patients were 76 +/- 12.5 years and 82 patients (61.2%) were male. The median NIHSS scores of the patients at admission was 5 +/- 4.5. Mortality during the hospitalization was seen in 8 patients (6%). The median neutrophil to lymphocyte ratio value of the patients at admission were found to be 2.6 +/- 3.4. Neutrophil to lymphocyte ratio and NIHSS scores of the patients at admission, duration of the hospitalization, mRS scores at discharge and mortality during hospitalization were found to be positively correlated. Conclusion: Neutrophil to lymphocyte ratio is a simple and easily measured marker and can be used as a potential indicator for prognosis in acute ischemic stroke. However further prospective multicenter investigations are required to confirm the role of neutrophil to lymphocyte ratio for predicting the prognosis in acute ischemic stroke patients.
