Пациенты с достоверным диагнозом СКВ, с высокой и средней степенью активности заболевания по индексу SLEDAI-2K (n=49), разделены на три группы: 40 больных получали РТМ, 5 пациентам назначался БЛМ, 4 больным проводилась комбинированная терапия (двойная анти-В-клеточная терапия) РТМ + БЛМ. Определение субпопуляций В-лимфоцитов в периферической крови методом многоцветной проточной цитофлюориметрии с использованием панели моноклональных антител к поверхностным мембранным маркерам В-лимфоцитов и клинико-иммунологическое обследование больных проводились до начала терапии генно-инженерными биологическими препаратами и каждые 3 мес в течение года.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Пациенты с высокой активностью СКВ (SLEDAI-2K 18±5) и поражением жизненно важных органов, как правило, имели более высокие уровни двойных негативных клеток «памяти» (r=0,52; p&lt;0,001) при относительно низких количествах наивных В-клеток (r=-0,54; p&lt;0,0007), по сравнению с больными без тяжелой органной патологии (SLEDAI-2K 8±2). Терапия РТМ к 3-му месяцу наблюдения приводила к заметному уменьшению количества наивных и двойных негативных В-клеток «памяти», в меньшей степени – «непереключенных» и «переключенных» В-клеток «памяти». Быстрое восстановление числа В-клеток «памяти» и плазмобластов после курса РТМ к 6-му месяцу от начала терапии должно оцениваться как предиктор раннего обострения СКВ. У всех 5 пациентов, получающих БЛМ на различных этапах контроля, наблюдалось уменьшение клинико-лабораторных признаков активности СКВ, а также угнетение наивных В-клеток, плазматических клеток и плазмобластов. Двойная анти-В-клеточная терапия наиболее эффективно обеспечивала снижение активности заболевания к 3-му месяцу, пролонгировала достигнутую ремиссию, способствовала достижению и сохранению низкого уровня В-лимфоцитов на последующих этапах контроля, дальнейшему сокращению количества плазмобластов и плазматических клеток, препятствовала синтезу аутоантител.</p></sec><sec><title>Заключение</title><p>Заключение. Оценка динамики субпопуляций В-лимфоцитов в периферической крови предоставляет новые возможности в определении нарушения функции и регуляции клеточного иммунитета у больных СКВ, может быть полезным диагностическим параметром для мониторинга аутоиммунного заболевания, а также являться ценным инструментом в оценке и прогнозировании ответа.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to study the baseline level and time course of changes in peripheral blood B cell subpopulations in patients with systemic lupus erythematosus (SLE) versus the clinical manifestations of the disease during therapy with rituximab (RTM) and belimumab (BLM).</p></sec><sec><title>Subjects and methods</title><p>Subjects and methods. 49 patients with a documented diagnosis of SLE and high and moderate SLEDAI-2K values were divided into three groups: 1) 40 patients received RTM, 2) 5 patients took BLM; 3) 4 patients had combination therapy (dual anti-B-cell therapy) with RTM + BLM. Peripheral blood B lymphocyte subpopulations were measured by multicolor flow cytometry using a panel of monoclonal antibodies against surface membrane markers of B lymphocytes; the patients underwent clinical immunological examination before therapy with biological agents and every 3 months during a year.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. Patients with high SLE activity (SLEDAI-2K 18±5) and involvement of vital organs had generally higher levels of double negative memory cells (r = 0.52; p &lt; 0.001) with relatively low counts of naive B cells (r=-0.54; p &lt; 0.0007) than those without severe organ pathology (SLEDAI-2K 8±2). RTM therapy at 3 month of follow-up resulted in a noticeable decrease in the number of naive and double negative memory B cells and to a lesser extent in that of non-switched and switched memory B cell. A rapid recovery of the count of memory B cells and plasmablasts after a RTM cycle at 6 months after therapy initiation should be evaluated as a predictor of early exacerbation of SLE. There was a reduction in the clinical and laboratory signs of SLE activity, as well as inhibition of naive B cells, plasma cells, and plasmablasts in all the 5 patients receiving BLM at various stages of follow-up. Dual anti-B cell therapy most effectively reduced disease activity at 3 months, prolonged the achieved remission, contributed to the achievement and maintenance of a low B lymphocyte level at later stages of control, to the further decline in the number of plasmablasts and plasma cells, and prevented the synthesis of autoantibodies.</p></sec><sec><title>Conclusion</title><p>Conclusion. Assessment of the time course of changes in peripheral blood B lymphocyte subpopulations provides new opportunities to identify impaired function and regulation of cellular immunity in patients with SLE, it may be a useful diagnostic parameter to monitor an autoimmune disease and a valuable tool to assess and predict a response. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>В-лимфоциты</kwd><kwd>системная красная волчанка</kwd><kwd>лечение</kwd><kwd>ритуксимаб</kwd><kwd>белимумаб</kwd></kwd-group><kwd-group xml:lang="en"><kwd>B lymphocytes</kwd><kwd>systemic lupus erythematosus</kwd><kwd>treatment</kwd><kwd>rituximab</kwd><kwd>belimumab</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, Насонова ВА, редакторы.
