ALOPESİ AREATA’DA TNF-α PROMOTÖR POLİMORFİZMİNİN ANALİZİ

AMAÇ: Alopesi Areata patogenezinde, değiş- miş T hücre aracılı bağışıklığın rol aldığını gösteren çok sayıda çalışma bulunmaktadır. Sitokinlerin ve kemokinlerin Alopesi Areata’nın immun sürecinde önemli rol oynamasından dolayı, Alopesi Areata’ya yatkınlık ile TNF-α-308G/A polimorfizmi arasındaki olası bağlantının Türk populasyonunda araştırılması amacıyla bu çalışma gerçekleştirildi. GEREÇ VE YÖNTEM: Sunulan vaka kontrol çalışmasına 107 Alopesi Areata hastası ve 113 sağlıklı kontrol bireyi dahil edildi. TNF-α-308G/A polimorfizminin genotiplendirmesi Polimeraz Zincir Reaksiyonu (PZR) ve Restriksiyon Enzim Analizi (REA) yöntemleri ile gerçekleştirildi. BULGULAR: Hasta ve kontrol gruplarında TNF-α-308 G/A genotiplerinin ve allel frekanslarının dağılımı arasında anlamlı bir bağlantı bulunamadı (p=0.673 ve p=0.177, sırasıyla). Benzer şekilde, TNF-α-308 G/A polimorfizmi ile Alopesi Areata’nın klinik bulguları arasında fark tespit edilemedi. SONUÇ: Bu çalışma, TNF-α-308 G/A polimorfizminin Türk populasyonunda Alopesi Areata gelişiminde önemli bir rol oynamadığını göstermektedir.
