Abstract

Objective: Telaprevir-based triple therapy for chronic hepatitis C virus (HCV) patients with genotype 4 is not recommended potently by the guidelines. There are few studies in the literature related to this issue. This study showed the antiviral activity and safety of telaprevir-based regimens in the treatment of treatmentexperienced genotype 4 chronic HCV-infected patients.Materials and Methods: This retrospective study consisted of 12 genotype 4 HCV-infected patients. All patients received 12 weeks of telaprevir in combination with 24 weeks of pegylated interferon (PEG-IFN) alpha and ribavirin (RBV).Results: The sustained virological response (SVR) rate was six of 12 (50%). Notably, the rate of SVR in prior relapsers was 75% (6 of 8). SVR could not be achieved in non-responders.Conclusion: Telaprevir, a potent HCV NS3-4A protease inhibitor, has been used as monotherapy and in combination with PEG-IFN/RBV in patients infected with genotype 1, 2 and 3 HCV. Limited clinical data suggest that telaprevir has activity against genotype 4 HCV. In this study, it was observed that the addition of telaprevir to the standard regimen had a greater activity on treatment relapse patients with genotype 4.

Özet

Amaç: Telaprevir bazlı üçlü tedavi ders kitaplarındaki önerilere dayanılarak genotip 4 hepatit C virüslü (HCV) hastalarda önerilmemektedir. Literatürde genotip 4 HCV pegile interferon/ribavirin (PEG-İFN/RBV) tedavi deneyimli ve kalıcı viral yanıt alınamamış hastalarda telaprevir bazlı üçlü tedavinin etkinliğini belirleyen az sayıda çalışma bulunmaktadır. Çalışmada bu konuda literatüre katkıda bulunmayı amaçlanmıştır.Gereç ve Yöntemler: Çalışma retrospektif olarak dizayn edilmiş olup daha önceden PEG-İFN/RBV tedavisi almış ve nüksetmiş ya da yanıtsız olarak değerlendirilmiş 12 genotip 4 HCV enfeksiyonlu hasta alındı. Hastaların tedavi bitiminden 24 hafta sonra kalıcı viral yanıtları (KVY) kaydedildi.Bulgular: KVY'li tüm hastaların altısı (%50) alındı. KVY'si alınan hastaların tamamı PEG-İFN/RBV tedavisi sonrası nüks hastalar olduğu görüldü. PEG-İFN/RBV tedavisine cevapsız olan dört hastanın hiçbirinde KVY alınamadı.Sonuç: Telaprevir, etkili bir NS3-4A proteaz inhibitörü olup PEG-İFN/RBV ile ya da tek başına genotip 1, 2, 3 HCV hastaların tedavisinde kullanılmaktadır. Genotip 4'te kullanımına yönelik yapılan çalışmalar sınırlıdır. Çalışmamız, telaprevir bazlı PEG-İFN/RBV tedavisinin genotip 4 relaps 15 hastalarında KVY'yi önemli oranda arttırdığını göstermektedir.
