Материал и методы. Иммунофенотипирование плазматических клеток костного мозга выполнили 17 больным ММ в возрасте от 43 до 62 лет (медиана возраста 55 лет), с помощью 4-цветной проточной цитофлюориметрии на аппарате Cytomics FC 500 (“Beckman Coulter”, США). В работе использовали панель моноклональных антител CD138/CD38/CD45/CD19/CD117/CD56. Всего было подсчитано 200 000– 500 000 событий в исходном гейте по FS против SS, плазматические клетки выделяли в «гейте» CD138/ CD38. МРБ-негативность определяли в случае достижения порогового значения менее 0,01%. Всего было проанализировано 37 образцов костного мозга от 17 больных. Иммунофенотипирование выполняли: до 1-й ауто-ТГСК, после 1-й ауто-ТГСК и после 2-й ауто-ТГСК. Результаты и обсуждение. Во всех образцах костного мозга плазматические клетки характеризовались экспрессией обоих маркеров CD138/CD38, а также слабой экспрессией CD45 или ее отсутствием (CD45dim/neg-). Иммунофенотип плазматических клеток, представленный тремя маркерами CD19, CD117, CD56, изменялся на различных этапах лечения. При сравнении и анализе количественной экспрессии аберрантных маркеров перед и после 1-й ауто-ТГСК отмечалось статистически значимое их снижение (аберрантных плазматических клеток). У 6 (35,3%) из 17 больных удалось достичь МРБ-негативности после 1-й ауто-ТГСК. Иммунофенотипирование с помощью проточной цитофлюориметрии является высокочувствительным методом, позволяющим выявлять экспрессию аберрантных маркеров плазматических клеток, а также прослеживать их в динамике на фоне интенсивной терапии. В результате проведенного исследования была подтверждена эффективность высокодозной химиотерапии с последующей аутоТГСК. В процессе лечения выявлена гетерогенность аберрантной экспрессии плазматических клеток.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study is to investigate the immunophenotype of bone marrow plasma cells in patients with multiple myeloma (MM) before and after the transplantation of autologous hematopoietic stem cells (autologous HSCT), and to assess response to the treatment determine the frequency of the lack of achievement of minimal residual disease (MRD) negativity as a result of the treatment. Material and methods. Immunophenotyping of marrow plasma cells was performed in 17 MM patients aged from 43 to 62 years (median age 55 years). Four color flow cytometry (Cytomics FC unit 500, "Beckman Coulter", USA) and the panel of monoclonal antibodies CD138/CD38/CD45/CD19/CD117/CD56 were used. In total, there were estimated 200,000--500,000 events in the initial Gate for forward scatter (FS) vs side scatter (SS). Plasma cells were isolated in Gate CD138/CD38. MRD-negativity was determined as the achievement of threshold value less than 0.01%. 37 bone marrow samples from 17 patients were analyzed. Immunophenotyping was performed before the 1st autologous HSCT, after the 1st autologous HSCT and after the 2nd autologous HSCT. Results and discussion. In all samples bone marrow plasma cells were characterized by the expression of both CD138/CD38 markers and weak expression or absence of expression of CD45 (CD45dim/neg-). The immunophenotype of plasma cells was presented by three markers CD19, CD117, CD56 and varied at different stages of the treatment. The analysis of the quantitative expression of aberrant markers before and after the 1st autologous HSCT revealed a statistically significant reduction of aberrant plasma cells. In 6 (35.3%) of 17 patients MRD-negativity was successfully achieved after the 1st autologous HSCT. Conclusion. Immunophenotyping by flow cytometry is a highly sensitive method. It permit to detect the expression of aberrant markers of plasma cells, to obtain their changes during the therapy. The efficacy of high-dose chemotherapy with following autologous HSCT was confirmed. The heterogeneity of aberrant expression of plasma cells was found.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>множественная миелома</kwd><kwd>иммунофенотипирование</kwd><kwd>проточная цитофлюориметрия</kwd><kwd>плазматические клетки</kwd><kwd>аберрантная экспрессия</kwd><kwd>трансплантация аутологичных гемопоэтических стволовых клеток</kwd><kwd>минимальная резидуальная болезнь</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multiple myeloma</kwd><kwd>immunophenotyping</kwd><kwd>flow cytometry</kwd><kwd>plasma cells</kwd><kwd>aberrant expression</kwd><kwd>transplantation of autologous hematopoietic stem cells</kwd><kwd>Minimal residual disease</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">Reed C.B., Reece D.E., Kukreti V., Mikhael J.R., Chen C., Trudel S., et al.
