Abstract

It is necessary to use rapid and reliable methods for the diagnosis of hepatitis C virus (HCV) infections and follow up of the patients with HCV infection. The purpose of this study was to compare Cobas Amplicor system (Roche Diagnostics) and Cobas Taqman system (Roche Diagnostics) for the quantitative detection of HCV-RNA in clinical samples. Eightyfour serum samples that were sent to Hacettepe University Adult Hospital Clinical Microbiology Laboratory were included in the study. Fiftytwo (61.9%) of these samples were found to be positive by two methods while 32 (38.1%) samples were found to be negative by two methods. There were no discrepant results between the methods. When positive samples were evaluated it was found that Cobas Amplicor system detected an average HCV-RNA of 822.452 IU/ml while Cobas Taqman system detected an average HCV-RNA of 3.069.984 IU/ml. Since the mean number of HCV-RNA detected by Cobas Taqman system was 3.7 fold of the average number of HCV-RNA detected by Cobas Amplicor system, it was concluded that Cobas Taqman system was a reliable method for the follow up of patients with HCV infection.

Özet

HCV enfeksiyonlarının tanısında ve tanı konmuş hastaların takibinde, hızlı ve güvenilir sonuç veren yöntemlerin kullanılması gerekmektedir. Bu çalışma, HCV enfeksiyonunun tanısında klinik örneklerden kantitatif olarak HCV-RNA saptanmasında, Cobas Amplicor sistemi (Roche Diagnostics) ile Cobas Taqman sistemini (Roche Diagnostics) karşılaştırmak amacıyla yapılmıştır. Çalışmaya, Hacettepe Üniversitesi Erişkin Hastanesi Klinik Mikrobiyoloji Laboratuvarına HCV tanısı amacıyla gönderilen 84 serum örneği alınmıştır. Bu örneklerin 52 (%61.9)'sinde iki yöntemle de pozitif sonuç elde edilirken, 32 (%38.1) örnekte iki yöntemle de HCV-RNA saptanamamıştır. Yöntemler arasında uyumsuz sonuç tespit edilmemiştir. Pozitif sonuç elde edilen örnekler İncelendiğinde, Cobas Amplicor sistemiyle ortalama 822.452 IU/ml HCV-RNA elde edilirken, Cobas Taqman sistemiyle ortalama 3.069.984 IU/ml HCV-RNA elde edildiği görülmüştür. Çalışmamızda, Cobas Taqman sisteminin saptadığı HCV-RNA düzeyinin, Cobas Amplicor sisteminin saptadığı düzeyden yaklaşık 3.7 kat fazla olması nedeniyle, Cobas Taqman sisteminin HCV enfeksiyonlarının takibinde güvenle kullanılabilecek bir yöntem olduğu sonucuna varılmıştır.
