Проведен анализ биологического материла 122 пациентов с ВИЧ-инфекцией, находящихся на диспансерном наблюдении в Центре СПИД ГБУЗ Краевой клинической больницы № 2 (г. Владивосток), с целью выявления лекарственной устойчивости к 4 основным группам антиретровирусных препаратов.</p></sec><sec><title>   Результаты</title><p>   Результаты. Выявлен высокий удельный вес А6 (44,3 %) B (28,7 %) и C (8,2 %) генетических вариантов ВИЧ-1 у обследованных пациентов, при этом вероятность наличия лекарственной устойчивости к ненуклеозидным ингибиторам обратной транскриптазы в 10 раз выше при субтипе В, в сравнении с субтипом А6 (OR = 10,5). В отношении ингибиторов интегразы значительно чаще лекарственная устойчивость выявлялась в группе пациентов с В субтипом ВИЧ-1 (OR = 38,1). В 19,7 % случаев в общей выборке пациентов обнаружена устойчивость к одной группе препаратов, в 9 % – к 2; в 2,5 % – к 3 группам препаратов. В 8,2 % случаев выявлялась рекомбинантная форма А6/CRF02_AG. В 10,6 % определены различные генетические варианты ВИЧ-1, которые можно классифицировать как новые рекомбинантные или уникальные формы.</p></sec><sec><title>   Заключение</title><p>   Заключение. Результаты демонстрируют тенденцию к росту рекомбинантных типов ВИЧ-1 в регионе, изменение общего генетического ландшафта субтипов ВИЧ с наличием достоверных различий по связи мутаций, ассоциированных с лекарственной устойчивостью к некоторым группам препаратов антиретровирусной терапии при В и не-В субтипах ВИЧ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Objective</title><p>   Objective. To describe the drug resistance and genetic diversity of HIV-1 among patients in Primorsky Krai in 2024.</p></sec><sec><title>   Materials and methods</title><p>   Materials and methods. A biological material analysis was conducted on 122 HIV-infected patients under dispensary observation at the at the AIDS Center of Regional Hospital No. 2 (Vladivostok, Russia) in order to identify the drug resistance to four main classes of antiretroviral agents.</p></sec><sec><title>   Results</title><p>   Results. A high prevalence of genetic variants A6 (44.3 %), B (28.7 %), and C (8.2 %) of HIV-1 was observed among the examined patients. The likelihood of non-nucleoside reverse transcriptase inhibitor resistance was found to be tenfold higher in subtype B compared to subtype A6 (OR = 10.5). The integrase inhibitor resistance was significantly more frequently detected in the subgroup of patients with HIV-1 subtype B (OR = 38.1). In the overall patient sample, the drug resistance was identified in 19.7 % of cases for one group of antiretroviral medications, in 9 % for two groups, and in 2.5 % for three groups of medications. A recombinant form A6/CRF02_AG was detected in 8.2 % of cases. Additionally, 10.6 % of cases exhibited various genetic variants of HIV-1 which can be classified as new recombinant or unique forms.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. The results demonstrate a rising trend in recombinant types of HIV-1 within the region, reflecting changes in the overall genetic landscape of HIV subtypes, with significant variations in the mutation patterns associated with drug resistance across certain groups of antiretroviral therapy in both B and non-B subtypes of HIV.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ВИЧ</kwd><kwd>лекарственная устойчивость</kwd><kwd>антиретровирусная терапия</kwd><kwd>секвенирование</kwd><kwd>генетические варианты</kwd><kwd>СПИД</kwd></kwd-group><kwd-group xml:lang="en"><kwd>HIV</kwd><kwd>drug resistance</kwd><kwd>antiretroviral therapy</kwd><kwd>sequencing</kwd><kwd>genetic variants</kwd><kwd>AIDS</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Данное исследование выполнено за счет средств ФГБОУ ВО ТГМУ Минздрава России в рамках реализации программы стратегического академического лидерства «Приоритет-2030»</funding-statement><funding-statement xml:lang="en">This study was carried out at the expense of the Federal State Budgetary Educational Institution of Higher Education TSMU of the Ministry of Health Russia as part of the implementation of the strategic academic leadership program “Priority 2030”</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">UNAIDS.
