Предварительные сообщения показали, что функция В-клеток и гуморальный иммунный ответ могут быть модулированы под влиянием ингибитора рецепторов ИЛ6.Цель исследования – оценить влияние 12-месячной терапии тоцилизумабом (TЦЗ) на фенотип B-клеток и экспрессию генов при РА и проанализировать связь между субпопуляциями B-клеток и активностью РA.Материал и методы. Обследовано 24 пациента с РА (20 женщин и 4 мужчины); медиана возраста составила 55 [49; 64] лет; продолжительности болезни – 72 [24; 108] мес; DAS28 – 5,8 [5,3; 6,3]; все больные были серопозитивны по ревматоидному фактору (РФ), 87% – по антителам к циклическому цитруллинированному пептиду (АЦЦП). Пациенты получали ТЦЗ из расчета 8 мг/кг каждые 4 нед. После 12 мес лечения согласно критериям эффективности EULAR (DAS28) хороший эффект был достигнут у 54%, удовлетворительный – у 46% больных РА. Контрольная группа состояла из 29 добровольцев (21 женщина и 8 мужчин; медиана возраста – 58,5 [53,0; 62,0] года). Иммунофенотипирование лимфоцитов периферической крови проводили при включении в исследование и через 12 мес. Абсолютное и относительное количество CD19+B-лимфоцитов, B- клеток памяти (CD19+CD27+), непереключенных (CD19+IgD+CD27+) и переключенных (CD19+IgD-CD27+) В-клеток памяти, наивных (CD19+IgD+CD27-), двойных негативных (CD19+IgD-CD27-), транзиторных (CD19+IgD+CD10+CD38++CD27) B-клеток, плазмоцитов (CD19+СD38+) и плазмобластов (CD19+СD38+++IgD-CD27+CD20-) определялось методом многоцветной проточной цитофлуорометрии.Результаты и обсуждение. У больных РА относительное и абсолютное количество B-клеток памяти (CD19+CD27+) (1,3 [0,9; 1,7]%, 0015 [0,001; 0,003]•109/л), переключенных В-клеток памяти (CD19+IgDCD27+) (6,8 [3,6; 11,6]%, 0,01 [0,005; 0,02]•109/л) и абсолютное число транзиторных В-клеток (CD19+CD38++CD10+IgD+CD27-) (0,00009 [0; 0,00028]•109/л) оказалось ниже, чем у доноров: 2,2 [1,1; 3,0]%, 0,003 [0,001; 0,007]•109/л; 12,8 [9,3; 17,0]%, 0,02 [0,01; 0,04]•109/л; 0,0001 [0; 0,0003]•109/л соответственно (p&lt;0,05 для всех случаев). Через 12 мес после начала терапии ТЦЗ определялось снижение относительного и абсолютного количества плазмобластов (CD19+СD38+++CD27+IgD-CD20-) с 0,15 [0,1; 0,3] до 0,1 [0,01; 0,1]% и с 0,0003 [0,00007; 0,004]•109/л до 0,0001 [0; 0,0003]•109/л соответственно (p&lt;0,05). При этом относительное и абсолютное количество B-клеток памяти (CD19+CD27+) и переключенных клеток памяти (CD19+CD27+IgD-) у пациентов с РА оставалось ниже, чем у доноров: 1,0 [0,7; 1,2] и 2,2 [1,1; 3,0]%; 0,001 [0,006; 0,003]•109/л и 0,003 [0,001; 0,007]•109/л; 3,1 [1,1; 4,2] и 12,8 [9,3; 17,0]%; 0,003 [0,002; 0,006]•109/л и 0,02 [0,01; 0,04]•109/л соответственно (p&lt;0,05 для всех случаев). Численность других субпопуляций В-лимфоцитов через 12 мес существенно не изменилась. У больных РА при включении в исследование были выявлены корреляции между абсолютным количеством B-клеток памяти (CD19+CD27+) и уровнем С-реактивного белка (r=0,50; p&lt;0,05); абсолютным количеством плазмобластов (CD19+СD38+++CD27+IgD-CD20-) и содержанием РФ (r=0,41 и r=0,52; p&lt;0,05). Корреляций субтипов В-клеток с клинико-лабораторными показателями через 12 мес после назначения ТЦЗ не отмечалось.Заключение. Иммунофенотипирование субтипов В-лимфоцитов периферической крови показало уменьшение относительного и абсолютного количества B-клеток памяти (CD19+CD27+) и переключенных B-клеток памяти (CD19+CD27+IgD-) у больных РА по сравнению со здоровыми донорами. Выявленные корреляции между числом В-клеток памяти, плазмобластов и значениями лабораторных показателей у больных с высокой активностью РА могут свидетельствовать об участии В-лимфоцитов в патогенезе РА. Наблюдалось снижение уровня плазмобластов после 12 мес терапии ТЦЗ.</p></abstract><trans-abstract xml:lang="en"><p>The clinical efficacy and safety of interleukin-6 (IL-6) receptor blockade have been well studied, but the data on the impact of therapeutic inhibition of IL-6 on B cells are scarce and contradictory. Preliminary reports have shown that B cell function and a humoral immune response may be modulated by an IL-6 receptor inhibitor.Objective: to assess the effect of 12-month tocilizumab (TCZ) therapy on B-cell phenotype and gene expression in RA and to analyze the association between B-cell subsets and RA activity.Subjects and methods. Examinations were made in 24 active RA patients (20 women and 4 men) (median age, 55 [49; 64] years; disease duration, 72 [24; 108] months; DAS28 5.8 [5.3; 6.3]; the patients were seropositive for rheumatoid factor (RF) (100%) and for anti-cyclic citrullinated peptide antibodies (87.3%). The patients received TCZ 8 mg/kg every 4 weeks. After 12 months of therapy, 54% of patients were categorized as good responders, 46% as moderate responders according to the EULAR response criteria. A control group consisted of 29 volunteers (21 women and 8 men; median age, 58.5 [53.0; 62.0] years). Peripheral blood lymphocytes were immunophenotyped at the time of enrollment and after 12 months. The absolute and relative counts of CD19+B lymphocytes, memory B cells (CD19+CD27+), non-switched memory B cells (CD19+IgD+CD27+), switched memory B cells (CD19+IgDCD27+), naive (CD19+IgD+CD27-), double-negative (CD19+IgD-CD27-), transitional (CD19+IgD+CD10+CD38++CD27) B cells, plasma cells (CD19+СD38+), and plasmablasts (CD19+СD38+++IgD-CD27+CD20-) were estimated using multicolor flow cytometry. Results and discussion. The relative and absolute counts of memory B cells (CD19+CD27+) (1.3 [0.9; 1.7]%, 0015 [0.001; 0.003]•109/l), switched memory B cells (CD19+IgD-CD27+) (6.8 [3.6; 11.6]%, 0.01 [0.005; 0.02]•109/l), and the absolute number of transitional B cells (CD19+CD38++CD10+IgD+CD27-) (0.00009 [0; 0.00028]•109/l) were found to be lower in RA patients than in donors: 2.2 [1.1; 3.0]%, 0.003 [0.001; 0.007]•109/l; 12.8 [9.3; 17.0]%, 0.02 [0.01; 0.04]•109/l; 0.0001 [0; 0.0003]•109/l, respectively (p&lt;0.05 for all cases). After 12 months of TCZ therapy initiation, there were decreases in the relative and absolute counts of plasmablasts (CD19+CD38+++CD27+IgD-CD20-) from 0.15 [0.1; 0.3] to 0.1 [0.01; 0.1]% and from 0.0003 [0.00007; 0.004]•109/l to 0.0001 [0; 0.0003]•109/l, respectively (p&lt;0.05). At the same time, the relative and absolute counts of memory B cells (CD19+CD27+) and switched memory B cells (CD19+CD27+IgD-) remained lower in RA patients than in donors: 1.0 [0.7; 1.2] and 2.2 [1.1; 3.0]%; 0.001 [0.006; 0.003]•109/l and 0.003 [0.001; 0.007]•109/l; 3.1 [1.1; 4.2] and 12.8 [9.3; 17.0]%; 0.003 [0.002; 0.006]•109/l and 0.02 [0.01; 0.04]•109/l, respectively (p&lt;0.05 for all cases). Following 12 months of TCZ therapy, the numbers of other B-cell subpopulations were not considerably altered. When included in the study, the patients with RA showed correlations between the absolute count of memory B cells (CD19+CD27+) and the level of C-reactive protein (r=0.50; p&lt;0.05); between the absolute count of plasmablasts (CD19+CD38+++CD27+IgD-CD20-) and the level of RF (r=0.41 and r=0.52; p&lt;0.05). There were no correlations of B cell subsets with clinical and laboratory findings after 12 months of TCZ initiation.Conclusion. Immunophenotyping of peripheral blood B lymphocyte subsets showed the lower relative and absolute counts of memory B cells (CD19+CD27+) and switched memory B cells (CD19+CD27+IgD-) in RA patients than in healthy donors. The found correlations between the counts of memory B cells and plasmablasts and the values of laboratory parameters in patients with high RA activity may suggest that B lymphocytes are involved in the pathogenesis of RA. There was a decline in plasmablast levels after 12 months of TCZ therapy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ревматоидный артрит</kwd><kwd>ингибитор рецепторов интерлейкина 6</kwd><kwd>тоцилизумаб</kwd><kwd>CD19+В-клетки</kwd><kwd>В-клетки памяти</kwd><kwd>наивные В-клетки</kwd><kwd>двойные негативные В-клетки</kwd><kwd>проточная цитофлуорометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rheumatoid arthritis</kwd><kwd>interleukin-6 receptor inhibitor</kwd><kwd>tocilizumab</kwd><kwd>CD19+ B cells</kwd><kwd>memory B cells</kwd><kwd>naive B cells</kwd><kwd>double negative B cells</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">Насонов ЕЛ.
