Проведен анализ 259 клинических образцов цельной крови ВИЧ-инфицированных пациентов без опыта приема антиретровирусной терапии, которые наблюдались в ГКУЗ Московской области «Центр по профилактике и борьбе со СПИДом и инфекционными заболеваниями». Анализ включал в себя следующие этапы: экстракцию провирусной ДНК, амплификацию области генома вируса, содержащей ген vpu, секвенирование продуктов амплификации, генотипирование, сравнение консервативности и аминокислотных замен в последовательностях белка Vpu у ЛЖВ с различными стадиями заболевания.</p><p>Результаты и их обсуждение. В 255 из 259 (98,4%) клинических образцах был идентифицирован вариант вируса субсубтипа А6. Получена консенсусная последовательность белка Vpu суб-субтипа А6, которая содержала 81 аминокислоту. Достоверных различий в консервативности последовательностей белка Vpu у вариантов ВИЧ-1, полученных от пациентов с различной стадией заболевания, обнаружено не было. Аминокислотная замена P3A достоверно чаще встречалась у ЛЖВ со второй стадией ВИЧ-инфекции.</p></sec><sec><title>Заключение</title><p>Заключение.

In 255 out of 259 (98.4%) clinical samples, a sub-subtype A6 virus variant was identiﬁed. The consensus sequence of the Vpu sub-subtype A6 protein was obtained, which contained 81 amino acids. No signiﬁcant differences in the conservation of Vpu protein sequences were found between HIV-1 variants obtained from patients with different stages of the disease.
