У 6 пациентов клиническим проявлением был инфекционный фенотип заболевания синопульмональной локализации. У 4 пациентов диагностированы болезнь Крона, гемолитическая анемия, аутоиммунный гепатит. Уровень цитокинов IL-4, IL-10, IL-17, TNF-α, IFN-γ в сыворотке крови определяли методом ИФА, фенотипическую характеристику В-клеток, клеток периферической крови проводили методом проточной цитофлуориметрии.</p></sec><sec><title>Результаты</title><p>Результаты: у здоровых доноров доля В-клеток памяти составляет 30% от всех В-лимфоцитов, при инфекционной манифестации ОВИН – 12%, при аутоиммунной – 14%. Количество переключённых В-лимфоцитов памяти относительно общего пула В-2-клеток при инфекционной манифестации больше (2,3%), нежели при аутоиммунной (1,4%). У пациентов с инфекционной манифестацией по отношению к здоровым донорам группы сравнения увеличено содержание IFN-γ и TNF-α, отсутствуют отличия в сывороточном количестве IL-17, при аутоиммунных проявлениях содержание всех перечисленных цитокинов повышено, причем IFN-γ и TNF-α – в большей степени.</p></sec><sec><title>Заключение</title><p>Заключение: нарушение формирования В-лимфоцитов памяти и цитокиновая дисрегуляция иммунных процессов выявляются вне зависимости от варианта клинической манифестации ОВИН. Характер и степень изменений отличны в зависимости от клинического фенотипа заболевания.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: comparative characteristics of the subpopulation composition of B- lymphocytes and the cytokine spectrum of peripheral blood in infectious and non-infectious manifestations of CVID.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: the results of observation of 10 people diagnosed with CVID have been presented. Six patients the clinical manifestation had an infectious phenotype of the disease of synopulmonary localization. Four patients were diagnosed with Crohn's disease, hemolytic anemia, and autoimmune hepatitis. The level of cytokines IL-4, IL-10, IL-17, TNF-α, IFN-γ in blood serum was determined by the ELISA, the phenotypic characteristic of B cells of peripheral blood cells was carried out by flow cytofluorimetry.</p></sec><sec><title>Results</title><p>Results: the proportion of memory B cells in the healthy donors is 30% of all B-lymphocytes, on infectious manifestation of CVID – 12%, with autoimmune – 14%. The number of switched memory B-lymphocytes relative to the total pool of B-2 cells in infectious manifestation is greater (2.3%) than in autoimmune ones (1.4%). In patients with infectious manifestations the content of IFN-γ and TNF-α was increased inrelation to healthy donors of the comparison group, there were no differences in the serum amount of IL-17, with autoimmune manifestations, the content of all these cytokines was increased, IFN-γ and TNF-α being to a greater extent.</p></sec><sec><title>Conclusion</title><p>Conclusion: impaired formation of memory B-lymphocytes and cytokine dysregulation of immune processes are detected regardless of the variant of clinical manifestation of CVID. The nature and degree of changes differ depending on the clinical phenotype of the disease.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>В-лимфоциты памяти</kwd><kwd>фенотипы ОВИН</kwd><kwd>провоспалительные цитокины</kwd><kwd>иммунная дисрегуляция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>memory B lymphocytes</kwd><kwd>CVID phenotypes</kwd><kwd>proinflammatory cytokines</kwd><kwd>immune dysregulation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках государственного задания МЗ РФ на выполнение прикладных научных исследований, № госрегистрации: 121070200070-4 от 02.07.2021.</funding-statement><funding-statement xml:lang="en">The study was carried out within the framework of the state task of the Ministry of Health of the Russian Federation for the implementation of applied scientific research, state registration number: 121070200070-4 dated 02.07.2021.</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">Abbott JK, Gelfand EW.
