SERUM S-100 PROTEİNİNİN ENFARKT BOYUTU VE KLİNİK PROGNOZ İLE İLİŞKİSİ

Amaç: Akut iskemik inmelerde serum S-100 protein konsantrasyonlarının ölçülmesi ile enfarkt boyutu ve klinik prognoz ile olan korelasyonlarının belirlenmesi Yöntemler: Serum örnekleri 26 akut iskemik inmeli olgudan başvuru sırasında, 3. ve 7. günlerde toplandı. Serum S-100 protein düzeyleri Smart S-100 protein saptama reaktifi ile ölçüldü. Lezyonlar supratentoryal orta serebral arter (middle cerebral artery, MCA) enfarktları ve infratentoryal beyin sapı enfarktları olarak sınıflandırıldı. Tüm hastaların ilk 24 saat içinde çekilmiş kraniyal kompüterize tomografileri (computerized tomography, CT) ve ilk hafta içinde çekilmiş manyetik rezonans görüntülemeleri veya CT’leri mevcuttu. Nörolojik incelemeleri akut evrede “National Institute of Health Stroke Scale (NIHSS)” ile, 1. ve 6. aylarda “Modified Barthel Index (MBI)” ile yapıldı. İstatistiksel analizlerde ANOVA kullanıldı. Bulgular: MCA bölgesinin 2/3’ünden fazlasını tutan MCA enfarktları 3. günde en yüksek S-100 protein değerlerine, en yüksek NIHSS ve en düşük MBI skorlarına sahipti. İnfratentoryal enfarkt grubunda serum S-100 proteini ölçülemez düzeydeydi. Sonuç: MCA lezyonlarında S-100 proteini enfarkt boyu ve klinik prognoz ile ilişkilidir ve 3. gündeki artış ödem göstergesi olabilir.Anahtar Kelimeler: S-100 proteini, İskemik inme, Prognoz, Enfarkt boyutu
