(B, C, D) and HIV share modes of transmission and risk groups, in which the probability of infection with two or more of these viruses simultaneously is increased. Mutual worsening of the course of viral infections is important issue that occurs when HIV positive patients are coinfected with parenteral viral hepatitis.</p> <p><bold>The aim of the study</bold> was to determine the prevalence of HCV, HBV and HDV in HIV positive patients in the Novosibirsk region and to give molecular genetic characteristics of their isolates.</p> <p><bold>Materials and methods.</bold> Total 185 blood samples were tested for the presence of total antibodies to HCV, HCV RNA, HBV DNA and HDV RNA. The identified isolates were genotyped by amplification of the NS5B gene fragment for HCV, the polymerase gene for HBV and whole genome for HDV.</p> <p><bold>Results.</bold> The total antibodies to HCV were detected in 51.9% (95% CI: 44.7–58.9), HCV RNA was detected in 32.9% (95% CI: 26.6–39.5) of 185 studied samples. The distribution of HCV RNA positive cases completely repeated the distribution of HCV serological markers in different sex and age groups. The number of HCV infected among HIV positive patients increases with age. HCV subgenotypes distribution was as follows: 1b (52.5%), 3а (34.5%), 1а (11.5%), 2а (1.5%). 84.3% of detected HCV 1b isolates had C316N mutation associated with resistance to sofosbuvir and dasabuvir. The prevalence of HBV DNA in the studied samples was 15.2% (95% CI: 10.7–21.0). M204I mutation associated with resistance to lamivudine and telbivudine was identified in one HBV isolate. Two HDV isolates that belonged to genotype 1 were detected in HIV/HBV coinfected patients.</p> <p><bold>Conclusion.</bold> The data obtained confirm the higher prevalence of infection with parenteral viral hepatitis among people living with HIV in the Novosibirsk region compared to the general population of that region. The genetic diversity of these viruses among HIV infected individuals is similar to that observed in the general population.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Вирусы парентеральных гепатитов B, C, D (ВГВ, ВГС, ВГD) и иммунодефицита человека (ВИЧ) характеризуются сходными путями передачи и группами риска, в которых повышена вероятность приобретения одновременно сразу двух и более из этих инфекций. Взаимное усугубление течения вирусных инфекций является важной проблемой, возникающей при коинфицировании ВИЧ-положительных пациентов парентеральными вирусными гепатитами.</p> <p><bold>Цель работы.</bold> Определение встречаемости и молекулярно-эпидемиологической характеристики генетических вариантов ВГВ, ВГС и ВГD, выявленных среди ВИЧ-положительных пациентов в Новосибирской области.</p> <p><bold>Материалы и методы.</bold> В 185 исследуемых пробах определяли наличие суммарных антител к ВГС, РНК ВГС, ДНК ВГВ и РНК ВГD. Положительные образцы генотипировали путём амплификации фрагмента гена <italic>NS</italic><italic>5</italic><italic>b</italic> для изолятов ВГС, гена <italic>pol</italic> для изолятов ВГВ и полногеномной последовательности для изолятов ВГD.</p> <p><bold>Результаты.</bold> Среди 185 исследуемых образцов суммарные антитела к ВГС были обнаружены в 51,9% (95% ДИ 44,7–58,9), РНК ВГС – в 32,9% (95% ДИ 26,6–39,5). Распределение генетического материала ВГС в различных половозрастных группах полностью повторяло распределение серологических маркеров. Инфицирование ВГС у ВИЧ-позитивных лиц имеет тенденцию к увеличению с возрастом. Распределение субгенотипов в изучаемой выборке изолятов ВГС имеет следующие особенности: 1b – 52,5%, 3а – 34,5%, 1а – 11,5%, 2а – 1,5%. 84,3% изолятов ВГС субгенотипа 1b имеют мутацию C316N, ассоциируемую с развитием резистентности к лечению софосбувиром и дацабувиром. Встречаемость ДНК ВГВ в исследуемых пробах составила 15,2% (95% ДИ 10,7–21,0). В одном изоляте ВГВ определена мутация M204I, связанная с устойчивостью к лечению ламивудином и телбивудином. Среди ВИЧ-/ВГВ-инфицированных пациентов обнаружено 2 изолята ВГD, относящихся к генотипу 1.</p> <p><bold>Заключение. </bold>Полученные данные подтверждают факт более широкого распространения инфицирования парентеральными вирусными гепатитами среди ВИЧ-позитивных лиц Новосибирской области по сравнению с условно здоровым населением. Генетическое разнообразие вариантов этих вирусов среди ВИЧ-инфицированных аналогично разнообразию, наблюдаемому в общей популяции.</p></trans-abstract><kwd-group xml:lang="en"><kwd>coinfection</kwd><kwd>hepatitis B virus</kwd><kwd>hepatitis C virus</kwd><kwd>hepatitis D virus</kwd><kwd>HIV</kwd><kwd>genotyping</kwd><kwd>Novosibirsk region</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>коинфицирование</kwd><kwd>вирус гепатита В</kwd><kwd>вирус гепатита С</kwd><kwd>вирус гепатита D</kwd><kwd>ВИЧ</kwd><kwd>генотипирование</kwd><kwd>Новосибирская область</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">ФБУН «Государственный научный центр вирусологии и биотехнологии «Вектор» Роспотребнадзора</institution></institution-wrap><institution-wrap><institution xml:lang="en">State Scientific Center of Virology and Biotechnology “Vector” of the Federal Service for Surveillance of Consumer Rights Protection and Human Welfare (Rospotrebnadzor)</institution></institution-wrap></funding-source><award-id>ГЗ-2/22</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Gonzalez V.D., Falconer K., Blom K.G., Reichard O., Mørn B., Laursen A.L., et al.
