Abstract (2. Language): 
Hepatitis C virus (HCV) is closely related to pestiviruses and flaviviruses. It was cloned from copy DNA (cDNA) extracted from infectious chimpanzee plasma in 1988. HCV is now recognized as the major causative agent for non- A, non-B hepatitis (NANBH). Based upon nucleic acid sequence analysis, six major HCV genotypes have been identifed worldwide. Enzyme-linked immunosorbant assays (ELISA), recombinant immunoblot assays (RIBA), synthetic peptide assays, polymerase chain reaction (PCR) are utilized for diagnosis. HCV may cause acute and chronic hepatitis, cirrhosis (CIR), hepatocellular carcinoma (HCC). The main route of transmission is parenteral, and most HCV-infected individuals are either IV drug users or recipients of blood products that in the past had not been screened for anti-HCV. Mother-to-infant transmission occurs in about 10% of HCV RNA positive mothers, mainly when maternal virus titers are high. Sexual transmission of HCV is probably absent or rare. There has not been HCV vaccine yet. Interferon is the only agent of proven efficacy in treatment of hepatitis C. The aim of this review is to revise new classification, genotypes, new diagnostic approaches and new treatment protocols about HCV.
Abstract (Original Language): 
Hepatit C virusu (HCV) pestiviruslar ve flaviviruslar ile yakından ilişkilidir. 1988'de infekte şempanzelerin plazmasından elde edilen copy DNA (cDNA)'dan klonlandı. HCV non-A, non-B hepatit grubunda major etkendir.Nükleik asit sequence analizleri temel alınarak tüm dünyada 6 büyük HCV genotipi tanımlanmıştır. Tanıda enzim-linked immunosarbant assays (ELISA), rekombinant immunoblot assays (RIBA), sentetik peptid assays, polimeraz zincir reaksiyonu (PCR) kullanılır. HCV akut ve kronik hepatit, siroz (CIR), hepatoselüler karsinom (HCC) meydana getirebilir.Ana bulaşma yolu parenteraldir ve diğer HCV infekte kişilerin çoğu İV ilaç kullananlar veya geçmişte anti-HCV antikorları bakılmadan kan ürünlerini kullananlardır. HCV pozitif annede virus titresi yüksek ise anneden fetusa geçiş oranı %10 civarındadır. Seksüel geçiş nadir veya yoktur. HCV aşısı henüz bulunamamıştır. Interferon tedavide kullanılan tek ilaçtır. Bu derlemeninin amacı HCV hakkında yeni sınıflandırma, genotipler, yeni tanı yaklaşımları ve tedavi protokollerini gözden geçirmektir.
