Установлен факт более частого выявления суб-субтипа А1 (84,7%) ВИЧ-1 у лиц, живущих с ВИЧ, в сравнении с пациентами с сочетанным инфицированием ВИЧ и хроническим гепатитом С (62,8%). Среди последних уровень распространенности рекомбинантных форм ВИЧ-1 оказался в 2,7 раза выше (32,6%) относительно ВИЧ-моноинфицированных (11,9%). У пациентов с сочетанной инфекцией ВИЧ – хронический гепатит С выявлена более частая регистрация субтипа 3а вируса гепатита С (49,1%). Реже встречались геноварианты 1b (40,6), 2 (5,7%) и 1a (4,7%). При этом в целом среди лиц, инфицированных ВИЧ и вирусом гепатита С, и пациентов с хроническим гепатитом С – моноинфекцией отличий в распределении генотипов вируса гепатита С практически не отмечено. Наряду с оценкой общих закономерностей циркуляции генетических вариантов возбудителей инфекционных заболеваний рекомендуется определение особенностей их распределения в зависимости от пола и наличия сочетанного инфицирования другими вирусными агентами.</p></abstract><trans-abstract xml:lang="en"><p>A comparative analysis of HIV-1 and hepatitis C virus (HCV) among patients with monoinfection as well a co-infection residing in constituent entities of the Far Eastern Federal district. It was established that HIV-1 sub-subtype A1 (84.7%) was detected more frequently among people living with HIV (PLWH) compared to individuals co-infected with HIV-1 and HCV (62.8%). Among the latter, prevalence of HIV-1 recombinant forms was 2.7 times higher (32.6%) compared to HIV monoinfected people (11.9%). HCV subtype 3a was identified more frequently among patients co-infected with HIV-1 and HCV (49.1%). HCV 1b (40.6%), 2 (5.7%) and 1a (4.7%) genovariants were less common. However, in general, there were practically no differences in the distribution of HCV genotypes be- tween examined groups. In addition to evaluating general patterns of pathogens genetic variants circulation, it is advisable to estimate peculiarities of their distribution depending on gender and presence of co-infection.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ВИЧ-инфекция</kwd><kwd>вирусный гепатит С</kwd><kwd>сочетанное инфицирование</kwd><kwd>генотипы</kwd><kwd>Дальневосточный федеральный округ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>HIV-infection</kwd><kwd>viral hepatitis C</kwd><kwd>co-infection</kwd><kwd>genotypes</kwd><kwd>Far Eastern Federal district</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">Азимова С.М., Дустов А.Д., Турсунов Р.А.
