Срок наблюдения составил 18 лет. Выявлено, что восстановление количества лимфоцитов в периферической крови приближается к референтным значениям после 180 дня после аллоТГСК. Процентное содержание NК-клеток выше референтных значений до +180 дня, тогда как нормализация абсолютного содержания NК-клеток происходит после +60 дня. Процентное содержание В-клеток приближается к референтным значениям после +60 дня, абсолютное - после +100 дня после трансплантации. Процентное содержание Т-клеток достигает нормальных значений к +30 дню, однако абсолютное содержание этих клеток нормализуется только к +365 дню после аллоТГСК. Среди Т-клеток преобладают цитотоксические Т-лимфоциты и их процентное содержание находится выше референтных величин в течение года после аллоТГСК, абсолютное содержание кратковременно нормализуется после +60 дня. Восстановление Т-хелперов, тимических мигрантов и Т-регуляторных клеток начинается после +100 дня, однако процентное и абсолютное содержание остаётся значительно ниже нормы и после года наблюдения. На протяжении всего времени наблюдения процентное соотношение клеток памяти Т-хелперов и цитотоксических Т-лимфоцитов ведет себя сбалансированно относительно друг друга до достижения референтных величин к 365 дню, а абсолютное количество наивных цитотоксических Т-лимфоцитов к 365 дню у некоторых пациентов превышает их. Анализ данных по восстановлению субпопуляций лимфоцитов периферической крови показывает необходимость динамического клинического и лабораторного контроля пациентов с ПИД, перенёсших аллоТГСК. В программу иммунологического мониторирования, помимо определения основных популяций лимфоцитов (В-, Т-лимфоцитов и NK), целесообразно включение определения минорных субпопуляций лимфоцитов, таких как Т-хелперы и цитотоксические Т-лимфоциты наивные и клетки памяти, тимические мигранты и Т-регуляторные клетки.</p></abstract><trans-abstract xml:lang="en"><p>33 patients with primary immunodeficiency (PID) who underwent hematopoietic stem cell transplantation (HSCT) were examined. The follow-up period was 18 years.It was found that the recovery of the number of lymphocytes in the peripheral blood is approaching the reference values after 180 days after alloHSCT. The percentage of NK cells is higher than the reference values before +180 days, while the normalization of the absolute content of NK cells occurs after +60 days. The percentage of B cells approaches the reference values after +60 days, the absolute value-after +100 days after transplantation. The percentage of T cells reaches normal values by +30 days, but the absolute content of these cells is normalized only by +365 days after alloHSCT. Among T-cells, cytotoxic T-lymphocytes predominate and their percentage is higher than the reference values for a year after alloHSCT, the absolute content is briefly normalized after +60 days. Recovery of T-helper cells, thymic migrants and T-regulatory cells begins after +100 days, but the percentage and absolute content remains significantly below the norm even after a year of observation. During the entire observation period, the percentage of memory cells of T-helper cells and cytotoxic T-lymphocytes behaves in a balanced manner relative to each other until the reference values are reached by day 365, and the absolute number of naïve cytotoxic T-lymphocytes exceeds them by day 365 in some patients. Analysis of data on recovery of peripheral blood lymphocyte subpopulations shows the need for dynamic clinical and laboratory control of patients with PID who have undergone alloHSCT. In addition to determining the main populations of lymphocytes (B-, T-lymphocytes, and NK), it is advisable to include the definition of minor subpopulations of lymphocytes, such as T-helper and cytotoxic T-lymphocytes naïve and memory cells, thymic migrants and T-regulatory cells in the immunological monitoring programme.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>трансплантация гемопоэтических стволовых клеток</kwd><kwd>первичные иммунодефициты</kwd><kwd>субпопуляции лимфоцитов</kwd><kwd>проточная цитометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hematopoietic stem cell transplantation</kwd><kwd>primary immunodeficiency</kwd><kwd>lymphocyte subpopulations</kwd><kwd>flow cytometry</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">International Union of Immunological Societies: 2017 Primary Immunodeficiency Diseases Committee Report on Inborn Errors of Immunity / C.
