Материалом исследования служил 31 образец плазмы крови от пациентов с хроническим гепатитом С с рецидивом заболевания на терапии препаратами прямого противовирусного действия. Образцы обследовали на наличие РНК ВГС. В случае выявления РНК ВГС осуществляли амплификацию с использованием комплекта праймеров, совместно фланкирующих гены NS3, NS5A, NS5B. После секвенирования нуклеотидных последовательностей указанных генов определяли субтип вируса и выявляли мутации лекарственной устойчивости.</p><p>Результаты и их обсуждение. Возраст пациентов варьировал от 33 до 62 лет и составил в среднем 45,8±8,38 года. Количество мужчин в группе преобладало по сравнению с женщинами — 21 (67%) и 10 (33%) соответственно. Результаты определения вирусной нагрузки варьировали от 3,1×103 до 4,2×107 МЕ/мл. Распределение генотипов ВГС в группе было следующим: 1а — 26% (n=8), 1b — 29% (n=9), 3a — 45% (n=14). Нуклеотидная последовательность участков NS3, NS5A, NS5B определена во всех образцах. Мутации, ассоциированные с лекарственной устойчивостью, были обнаружены в 87% случаев (n=27). Все выявленные мутации приводили к устойчивости вируса по крайней мере в отношении одного препарата, входящего в состав текущей схемы терапии пациента. У одного пациента были найдены аминокислотные замены сразу в трех регионах, что привело к возникновению устойчивости сразу к двум препаратам в схеме.</p></sec><sec><title>Заключение</title><p>Заключение. Проведение предварительного обследования пациентов, направленного на выявление мутаций лекарственной устойчивости к препаратам прямого противовирусного действия, способно повлиять на эффективность планируемого лечения и выбор оптимальной схемы терапии.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to identify the prevalence of drug resistance mutations in the hepatitis C virus among patients with relapse of the disease on therapy with direct antiviral drugs.</p><sec><title>Materials and methods</title><p>Materials and methods. The study material included 31 blood plasma samples from patients with chronic hepatitis C with relapse of the disease on therapy with direct antiviral drugs. Samples were screened for the presence of HCV RNA. In case of detection of HCV RNA, amplification was carried out using a set of primers jointly flanking the NS3, NS5A, NS5B genes. After sequencing the nucleotide sequences of these genes, the subtype of the virus was determined and drug resistance mutations were identified.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The age of the patients ranged from 33 to 62 and averaged 45.8±8.38 years. The number of men in the group prevailed compared to women — 21 (67%) and 10 (33%), respectively. Viral load determination results ranged from 3.1×103 to 4.2×107 IU/ml. The distribution of genotypes was as follows: 1a — 26% (n=8), 1b — 29% (n=9), 3a — 45% (n=14). The nucleotide sequence of the NS3, NS5A, NS5B regions was determined in all samples. Mutations associated with drug resistance were detected in 87% (n=27). In all identified cases, the mutations resulted in viral resistance to at least one drug included in the patient’s current treatment regimen. In one patient, amino acid substitutions were found in three regions at once, which led to the emergence of resistance to two drugs in the regimen.</p></sec><sec><title>Conclusion</title><p>Conclusion. Conducting a preliminary examination of patients to identify mutations of drug resistance to direct antiviral drugs can affect the effectiveness of the planned treatment and the choice of the optimal regimen.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>вирус гепатита С</kwd><kwd>препараты прямого противовирусного действия (ПППД)</kwd><kwd>лекарственная устойчивость</kwd><kwd>генотипы</kwd><kwd>мутации</kwd><kwd>молекулярная диагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hepatitis C virus</kwd><kwd>direct acting antivirals (DAAs)</kwd><kwd>drug resistance</kwd><kwd>genotypes</kwd><kwd>mutations</kwd><kwd>molecular diagnostics</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">World Health Organization.
