Abstract

Objective: In this study, the effects of genotypic differences on the clinical course of the disease, response to treatment and fibrosis were investigated in patients with hepatitis C virus (HCV) infection.Materials and Methods: Ninety-nine chronic HCV-infected patients and 95 controls were enrolled. The patients received pegylated interferon (PegIFN) + ribavirin (RBV) for 48 weeks and followed up for the next 48 weeks. Aspartate aminotransferase/platelet ratio index was used to determine the stage of liver fibrosis. DNA specimens were extracted from peripheral blood mononuclear cells and the interleukin (IL) 28B gene rs12979860, rs12980275, and rs8099917 were genotyped by the immune polymerase chain reaction-restriction fragment length polymorphism method. Results were analysed using the SPSS 16.0 and OpenEpi 2.2 softwares.Results: All patients had HCV genotype 1. Among the 99 HCV+ patients, in 26.3% spontaneous viral clearance, in 42.8% rapid viral response, 92% early viral response and in 72.6% sustained viral response was observed. The allele frequencies of IL28B single nucleotide polymorphisms (SNP), rs12979860, rs12980275, and rs8099917 were not identical in all samples (p<0.005). SNP rs12979860 CT genotype (p=0.010); rs12980275 GA genotype (p=0.010); and rs8099917 GT and TT genotypes (p=0.019 and 0.020, respectively) were strongly associated with rapid viral response in the overall sample. Conclusion: The determination of IL28B polymorphisms may be useful to individualize treatment options when using PEG/RBVbased therapies for chronic HCV infection but genetic characteristics of populations of the countries must be known

Özet

Amaç: Bu çalışmamızda hepatit C virüs (HCV) enfeksiyonu olan hastalarda genotipik farklılıkların hastalığın klinik gidişi, tedavi yanıtları ve fibrosis üzerine etkileri araştırılmıştır. Gereç ve Yöntemler: Çalışmaya 99 kronik aktif HCV enfeksiyonu olan hasta ve 95 sağlıklı kontrol dahil edildi. Hastaların tümü 48 hafta boyunca pegile interferon (PegIFN) + ribavirin (RBV) tedavisi aldı ve tedavi sonu 48 hafta takip edildi. Karaciğer fibrosis evresi için aspartat aminotransferaz/platelet skoru kullanıldı. DNA örnekleri deneklerin peripheral kan mononükleer hücrelerinden elde edildi ve immün polimeraz zincir reaksiyonu-restriksiyon parça uzunluk polimorfizmi yöntemiyle interlökin (IL) 28B rs12979860, rs12980275 ve rs8099917 genotiplendirmeleri yapıldı. Sonuçlar SPSS 16,0 ve OpenEpi 2,2 yazılımı ile analiz edildi.Bulgular: Tüm hastalar HCV genotip 1 hastası idi. Çalışmaya alınan deneklerde IL28B tek nükleotid polimorfizmi (TNP) (rs12979860, rs12980275 ve rs8099917) dağılımı farklılık gösteriyordu (p<0,005). TNP rs12979860 CT genotipi (p=0,010); rs12980275 GA genotipi (p=0,010); ve rs8099917 GT ve TT genotipleri (p=0,019 ve 0,020 sırasıyla) ve hızlı viral yanıt arasında kuvvetli ilişkili bulundu. Sonuç: Kronik HCV enfeksiyonu olan hastaların PegIFN+RBV ile tedavilerinin bireysel olarak belirlenmesinde IL28B polimorfizmlerinin bilinmesi faydalı olabilir. Fakat her ülkenin kendi genotipik karakteristiklerini bilmesi gereklidir.
