Identification of Drug Resistant Mutants of HBV (Hepatitis B Virus) by Direct Sequencing in Iranian Patients Treated with Lamivudine
Background and Aims: lamivudine is amongst the antiviral for drug chronic hepatitis B treatment. During therapy with lamivudine, variants may emerge with YMDD mutation in the reverse transcriptase (RT) region of polymerase gene. This mutation might have a role in drug resistant for HBV. Materials and Methods: HBV DNA extraction from serum sample of 88 patients, were subjected to nested PCR for ...
متن کاملUse of ALLGIO probe assays for detection of HBV resistance to adefovir in patients with chronic hepatitis B, Kerman, Iran.
Hepatitis B virus (HBV) infection is contagious with transmissiobn vertically or horizontally by blood products and body secretions. Over 50% of Iranian carriers contracted the infection prenatally, making this the most likely route of transmission of HBV in Iran. To evaluate the resistance to adefovir (ADV) therapy in patients with chronic hepatitis B infection, a study was conducted on 70 pat...
متن کاملارزیابی تکنیک های ICT،ELISA و Real Time PCR در تشخیص هپاتیت B در بیماران دیالیزی،تالاسمی و هموفیلی
Background and purpose: Recently, use of enzyme-linked immunosorbent assay (ELISA) and rapid Immunochromatographic test (ICT) in diagnosis and screening of patients with hepatitis B reduced the risk of hepatitis during blood transfusion. However, the incidence of hepatitis B is very high in high-risk patients such as hemodialysis, thalassemia and hemophilia which receive a lot of blood transfus...
متن کاملComplex dynamics of hepatitis B virus resistance to adefovir.
UNLABELLED In patients with hepatitis B e antigen-negative chronic hepatitis B, adefovir dipivoxil administration selects variants bearing reverse transcriptase rtN236T and/or rtA181V/T substitutions in 29% of cases after 5 years. The aim of this study was to characterize the dynamics of adefovir-resistant variant populations during adefovir monotherapy in order to better understand the molecul...
متن کاملSimultaneous detection of hepatitis B virus genotypes and mutations associated with resistance to lamivudine, adefovir, and telbivudine by the polymerase chain reaction-ligase detection reaction.
OBJECTIVES Detection of mutations associated to nucleos(t)ide analogs and hepatitis B virus (HBV) genotyping are essential for monitoring treatment of HBV infection. We developed a multiplex polymerase chain reaction-ligase detection reaction (PCR-LDR) assay for the rapid detection of HBV genotypes and mutations associated with lamivudine, adefovir, and telbivudine resistance in HBV-infected pa...
