Determination of Resistance Mutation in Chronic Hepatitis B Patients Using Antiviral Drugs at Our Hospital

Abstract: ÖZObjective: In this study, it is aimed to determine the mutations responsible for drug resistance in patients with chronic hepatitis B virus (HBV) infection received/receiving antiviral treatment at our hospital and to examine the patients in terms of the treatment applied and their HBV-DNA levels. Materials and Methods:One hundred and thirty-one samples taken from patients diagnosed with chronic hepatitis B infection between January 2010 and January 2015 at Necmettin Erbakan University Meram Faculty of Medic… Show more

“…While rtM204I substitution may be detected alone, rtM204V/S may be seen together with other mutations [4] . He et al [23] determined the frequency of rtM204I to be 71.88% and Wen et al [24] as 29.2%, whereas in Turkey the rates of isolated rtM204I were reported as 12% by Kırdar et al [25] , 9% by Timur et al [8] , 5.8% by Aydoğan et al [26] , 6.4% by Bozdayi et al [27] , and 1.5% by Saran et al [28] .…”

“…Rates of LAM resistance have been reported as 69.7% by Wen et al [24] in China, 52.9% by Wong et al [31] in Hong Kong, and 17.3% by Margeridon-Thermet et al [32] in California. Rates of HBV resistance to LAM in treatment-experienced patients in Turkey were reported as 42.6% by Sayan et al [33] , 28.8% by Timur et al [8] , 22.6% by Bozdayı et al [27] , 19.5% by Alagözlü et al [34] , 15.6% by Aydoğan et al [26] , and 7.6% by Saran et al [28] . Since LAM is generally used as a first-line therapy, LAM resistance is frequently detected in treatment-experienced chronic HBV patients.…”

“…Çalışmamızda, toplamda %77 oranında saptanan YMDD mutasyonu, yakın zamanda Saran ve ark. 'nın (12) yaptığı çalışmada %83 oranında belirlenmiştir. Çalışmada antiviral tedavi alan 131 KHB hastasında %9.1 oranında mutasyon saptanmış ve YMDD ile birlikte çeşitli kompensatuvar mutasyonlar ve ADV direncinden sorumlu rtN236T mutasyonu bildirilmiştir.…”
