Abstract

Aim: This study aimed to demonstrate the diagnostic and prognostic value of NR-2 peptides as a biomarker in acute ischemic stroke and to evaluate their correlation with the Glasgow Coma Scale (GCS) and the National Institutes of Health Stroke Scale (NIHSS).

Materials and Methods: The importance of NR-2 peptide level in diagnosis and prognosis in acute stroke was investigated cross-sectional and prospectively. The study included 101 patients, who presented to a tertiary healthcare facility and were diagnosed with acute stroke, and 57 healthy controls. In the whole study population, serum NR-2 peptide levels were measured using the ELISA method.

Results: The NR-2 peptide level was 6.32 ± 8.30 in the patient group and 3.91 ± 1.64 in the study group. The NR-2 peptide level was significantly higher in the patient group (p = 0.006). No correlation was detected between NR-2 peptide levels and scores in the GCS or NIHSS. The results indicated that NR-2 was a potential biomarker elevated in the early phase of acute stroke, but had no correlation with the prognosis of acute stroke.

Conclusion: Although our data shed light on the use of the NR-2 peptide level as a biomarker in the acute phase in patients with stroke, data are insufficient to predict prognosis. We think that larger, multicenter studies with longer follow-up periods are needed.

NR-2 antikor peptid düzeyinin akut iskemik inmede tanı, prognoz ve koma skorları ile ilişkisi var mıdır?

Abstract

Amaç: Bu çalışmanın birincil amacı akut iskemik inme’de biyobelirteç olarak NR-2 peptidinin tanısal ve prognostik değerini göstermek, ayrıca Glasgow koma skoru (GKS) ve Ulusal Sağlık Enstitüleri İnme Ölçeği (NIHSS) arasındaki ile ilişkisinin araştırılmasıdır.

Yöntemler: Akut inme de NR-2 peptid düzeyinin tanı ve prognozdaki önemi prospektif kesitsel olarak araştırılmıştır. Çalışmaya üçüncü basamak sağlık kuruluşuna bir yıl içerisinde başvurup akut inme tanısı kesinleşen 101 hasta ve 57 sağlıklı kontrol grubu alınmıştır. Tüm çalışma grubunda serumda NR-2 peptid düzeyi ELISA yöntemi ile ölçülmüştür. Elde olunan sonuçlar hastaların prognoz kriterini öngörebilecek olan koma skorlamaları ile ilişkisine bakılmıştır.

Bulgular: Elisa yöntemi ile ölçülen NR-2 peptid düzeyi hasta grubunda 6,32±8,30, kontrol grubunda 3,91±1,64 saptandı. NR-2 düzeyi hasta grubunda daha yüksek olup istatistiksel olarak anlamlı fark vardır (p:0,006). NR-2 düzeyi ile GKS ve NIHSS arasında ilişki saptanmamıştır. Bu sonuçlar ile NR-2 düzeyi akut inmede erken dönemde yüksek saptanılan potansiyel bir biyobelirteç olmasına karşın bu protein düzeyinin akut inme prognozu ile ilişkisi saptanmadı.

Sonuç: Sonuçlarımız NR-2 düzeyinin inmeli hastalarda biyomarker olarak akut dönemde kullanılabilmesi için ışık tutmakla birlikte, hastalığın prognozunu öngörmede yeterli verilere sahip değildir. Bu konuda daha fazla hasta popülasyonu ile çok merkezli, hastaların daha uzun süre takip prognozlarının izlenildiği çalışmalara ihtiyaç olduğunu düşünmekteyiz.
