چکیده

Amaç: Oksidan ve antioksidan dengedeki bozukluklar talasemi ve orak hücreli anemi gibi hemoglobinopatilerde saptanmıştır. Çalışmada düzenli olarak transfuzyon yapılan ve şelasyon tedavisi alan 11 beta talasemi major hastasında oksidan ve antioksidan özellikler çalışılmıştır. Gereç ve yöntem: Hastaların laboratuar değerleri cinsiyet ve yaşları çalışma grubuna uygun 10 sağlıklı çocuk ile karşılaştırılmıştır. Bulgular: Koruyucu bir antioksidan olan eritrosit superoksid dismutazı (ESOD) ve lipit peroksidasyonunun yıkım ürünü olan plazma malonildialdehid (MDA) düzeyleri çalışma grubunda sağlıklı çocuklara göre yüksek bulunmuştur. Serum vitamin E düzeyleri ise sağlıklı çocuklara gore düşük bulunmuştur. Sonuç: Talasemilerin patogenezinde demir yüklenmesi sonucu oluşan artmış oksidatif yıkım önemlidir. Ayrıca vitamin E gibi yağda eriyen vitaminlerin yetersizliği sonucu olarak antioksidan durumun bozulması oksidatif yıkımda artışa neden olur.
