Kronik hepatit C tedavisinde yeni seçenekler

Amaç: Kronik hepatit C (KHC) infeksiyonu tüm dünyada siroz ve karaciğer kanserinin en önemli nedenlerinden biridir. Hastaların tespit edilerek tedavi edilmesi bu olumsuz sonuçların ortaya çıkmasını büyük ölçüde önlemektedir. Günümüzde KHC tedavisinde önerilen standart tedavi şeması, pegile-interferon alfa 2a/2b ile birlikte ribavirin kombinasyonundan oluşmaktadır. Yanıtsız hastalarda yeni tedavi seçenekleri gündemdedir. Bu yazıda özellikle yanıtsız ve relaps gelişen hastalardaki tedavi seçeneklerinin değerlendirilmesi amaçlanmıştır. Ana bulgular: Tedaviye yanıt alınamayan ya da relaps gelişen hastalar için, yeni geliştirilen proteaz inhibitörü ilaçlar içinde telaprevir ve boceprevir ön plana çıkan iki ilaçtır. Sonuç: İncelenen son literatür verilerine göre yanıtsız ya da relaps gelişen KHC hastaları için proteaz inhibitörlerini içeren tedavi kombinasyonları yeni umutlar vaad etmektedir.

New options of chronic hepatitis C treatment

Objective: Chronic hepatitis C (CHC) is one of the important reasons of cirrhosis and hepatocellular carcinoma in the world. CHC patients should determine because of treatment of them may be prevent cirrhosis and hepatocellular carcinoma. Now, pegile-interferon 2a/2b and ribavirin combination is standard treatment for CHC. In this review treatment options for relapser or nonresponder CHC patients were evaluated. Main findings: Treatment in nonresponder or relapser patients is difficult due to absent of alternative certain treatment. But recently, new developed protease inhibitors may be new option for them. Telaprevir and boceprevir are two important new protease inhibitors. Conclusion: According to data obtained from the literature, protease inhibitors are promises new hope for relapser or nonresponder CHC patients.
