Introduction: Blood viscosity (BV) is an important blood property for determining the hemodynamic status. High BV causes blood stagnation and subsequent thrombotic reactions leading to cerebral infarction. However, clinical application of the measurement of BV is out of fashion due to the stereotype that the measurement results are within expectations with less clinical value. Hypothesis: Since the importance of BV remains unchanged in the pathogenesis of vascular diseases, BV values should still contain important information. We hypothesize that BV values may differ among stroke subtypes based on pathological condition. Methods: A new type of viscometer was recently developed using an electromagnetically spinning sphere (EMS) method, which enable us to measure small amount of samples quickly and sequentially in non-contact disposable manner. We measured BV in 100 healthy outpatients and 67 acute ischemic stroke patients (atherothrombotic: 28, lacunar: 23, and cardioembolic: 16) with EMS viscometer. The relationships between BV and hematological parameters were analyzed. The measurements in the acute stroke patients were performed a total of 4 times (Day0, Day2, Day7, and Day14 from the admission). Results: BV values in the healthy outpatients correlated more strongly with the total count of red blood cells and platelets (R2=0.6957) than with the hematocrit (R2=0.6435) in an exponential approximation. Compared with BV values in the healthy outpatients (4.57±0.76 mPa·s), Day0 BV values in the lacunar patients (5.37±1.11 mPa·s) were significantly higher (p<0.01), but those in the atherothrombotic patients (4.82±0.98 mPa·s) and in the cardioembolic patients (4.66±0.93 mPa·s) were not significantly different. In comparison between the values at Day 0 and Day 14, the lacunar patients alone showed a significant decrease from Day0 to Day14, suggesting that the lacunar patients suffered from dehydration at the onset. Conclusion: BV values at Day0 of lacunar infarction were significantly increased, which indicated contribution of dehydration to the onset of lacunar infarction. These measurements were performed with only 0.3ml of blood quickly and sequentially; therefore, the clinical application of the EMS viscometer appears to be promising.

ABSTRAK Pendahuluan: Acute ischemic stroke (AIS) merupakan jenis stroke dengan insidensi tertinggi utamanya pada kelompok usia lanjut. Saat ini, neuroimaging menjadi modalitas utama dalam penegakan diagnosis stroke, akan tetapi masih memiliki beberapa kelemahan, seperti ketersediaan yang terbatas, biaya yang mahal, waktu yang cukup lama untuk prosedurnya, serta pada beberapa kasus ditemukan hasil interpretasi gambar yang sering tidak konsisten pada stroke fase awal. Sehingga diperlukan alat diagnostik yang cepat, tepat, dan sederhana untuk diagnosis AIS. Saat ini, tipe tertentu dari circulating microRNAs (miRNAs) ditemukan dapat menjadi biomarker untuk diagnostik AIS. Tujuan kajian ini untuk melakukan profiling sekaligus mengevaluasi nilai diagnostik circulating miRNA pada pasien AIS dibandingkan dengan pasien hemorrhagic stroke (HS) dan individu sehat. Metode: Tinjauan sistematis ini mengumpulkan literatur dari PubMed, Science Direct, Clinical Trial.gov, Directory of Open Access Journal (DOAJ), dan Epistemonikos menggunakan metode standar dengan pedoman cochrane untuk tinjauan sistematis guna mengevaluasi nilai diagnostik dari circulating miRNA sebagai biomarker untuk AIS berdasarkan sensitivitas, spesifitas, dan nilai Area Under the Curve (AUC). Pembahasan: Dari 870 studi, 15 studi sesuai dengan kriteria inklusi. Dari studi yang ditinjau menunjukkan bahwa hsa-miR-106b-5P dan kombinasi miR-125a-5p + miR-125b-5p + miR-143-3p sebagai jenis miRNA yang paling efektif menjadi biomarker dalam mendiagnosis AIS dan membedakannya dengan individu sehat. Sedangkan miR-124-3p merupakan jenis miRNA yang paling efektif menjadi biomarker untuk membedakan AIS dan HS. Simpulan: Circulating miRNA yang diisolasi dari plasma, serum, dan darah manusia dapat digunakan sebagai biomarker diagnostik untuk AIS.   Kata Kunci: acute ischemic stroke, circulating microRNAs, diagnostik
