Материалы и методы: определение нуклеотидной последовательности белка NS5a (n=93), а также белка core (n=30) ВГС-1b проводилось методом прямого секвенирования амплифицированных фрагментов генома. Поиск мутаций, ассоциированных с лекарственной резистентностью, проводился в аминокислотных позициях 28, 29, 30, 31, 32, 58, 62, 92, 93 белка NS5a и аминокислотных позициях 70 и 91 белка core ВГС-1b. Результаты: 22,6% (21/93) исследованных изолятов ВГС-1b несли мутации, ассоциированные с лекарственной резистентностью к ингибиторам NS5a. В 10,8% последовательностей были выявлены замены L31M и Y93H, связанные с устойчивостью к большинству ингибиторов NS5a, а также менее значимые с клинической точки зрения замены L28M, R30Q, P58S/T, A92T. Доля лиц, инфицированных штаммами ВГС-1b, потенциально резистентными одновременно к препаратам интерферона и ингибиторам NS5a, составила 10% (10/30). Заключение: полученные данные свидетельствуют в пользу целесообразности предварительного исследования профиля резистентности ВГС-1b перед назначением терапии для предотвращения выбора заведомо неэффективного препарата.</p></abstract><trans-abstract xml:lang="en"><p>Aim. To determine the prevalence of amino acid substitutions in hepatitis C virus NS5a and core proteins which are associated with resistance to direct-acting antivirals and interferon in genotype 1b (HCV-1b) strains circulating in Russia. Materials and methods. Nucleotide sequences of NS5a (n=93) and core (n=30) of HCV-1b were obtained using direct sequencing of respective amplified genome fragments. The search for resistance associated substitutions was performed for amino acid positions 28, 29, 30, 31, 32, 58, 62, 92, 93 of NS5a, and 70 and 91 amino acid positions of core proteins, respectively. Results. The total proportion of HCV-1b strains carrying resistance associated substitutions in NS5a was 22,6% (21/93). The total detection rate of L31M and Y93H substitutions that are associated with resistance to the majority of NS5a inhibitors was 10,8%. Less clinically significant substitutions L28M, R30Q, P58S/T, A92T were detected too. The proportion of infections caused by HCV-1b strains that are potentially resistant both to interferon and NS5a inhibitors was 10% (10/30). Conclusion. Testing of HCV-1b infected patients for background resistance profile could be a useful tool to prevent the choosing of initially ineffective treatment regimen.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вирус гепатита С</kwd><kwd>лекарственная устойчивость</kwd><kwd>RAS</kwd><kwd>генетический полиморфизм</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Hepatitis C virus (HCV)</kwd><kwd>drug resistance</kwd><kwd>RAS</kwd><kwd>genetic polymorphism</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">European Association for the Study of the Liver.
