Настоящее исследование направлено на изучение зависимости между содержанием субпопуляций МС и показателями крови на этапе восстановления кроветворения после высокодозной химиотерапии с аутологичной трансплантацией гемопоэтических стволовых клеток у пациентов с множественной миеломой (ММ). МС оценивали методом проточной цитометрии в образцах периферической крови на этапе выхода из лейкопении (при количестве лейкоцитов в периферической крови более 1 x 109/л). Количество трансплантируемых CD34+CD45+ гемопоэтических стволовых клеток составило 4,38 x 106/кг (IQR (3,1-5,6) x 106/кг). Длительность выхода из лейкопении варьировала от 8 до 18 дней (Ме 12 дней). Содержание МС на этапе выхода из лейкопении не было связано с количеством CD34+ клеток/кг в трансплантате. Относительное содержание моноцитарных МС (М- МС, CD14+HLA-DRlow/-) прямо коррелировало с содержанием моноцитов на этапе выхода из лейкопении (R = 0,417, p = 0,002). Для гранулоцитарных МС (Г-МС, Lin-HLA-DR-CD33+CD66b+) была характерна обратная связь с количеством моноцитов (R = -0,493, p = 0,0003), при этом сопряженность с абсолютным содержанием нейтрофилов была слабо выражена (R = 0,273, p = 0,048). Содержание лимфоцитов на этапе выхода из лейкопении находилось в обратной связи с Г-МС (R = -0,347, p = 0,014) и не коррелировало с М-МС. При анализе длительность лейкопении обратная корреляционная связь с данным показателем была выявлена для процентного и абсолютного содержания М-МС (R = -0,347, p = 0,018 и R = -0,469, p = 0,0008 соответственно). Множественный регрессионный анализ показал зависимость длительности лимфопении от доли циркулирующих М-МС (р = 0,014) и количества трансплантированных CD34+ клеток/кг (р = 0,032). Согласно данным многофакторного дисперсионного анализа значимыми факторами для продолжительности лейкопении являлись количество трансплантированных CD34+ клеток/кг и содержание М-МС. При этом такие клинические параметры как глубина ответа и наличие минимальной остаточной болезни перед проведением высокодозной химиотерапии и трансплантации гемопоэтических стволовых клеток, а также стадия ММ не влияли на длительность восстановления кроветворения. Таким образом, полученные результаты свидетельствуют о сопряженности более высокого содержания М-МС с меньшей длительностью лейкопении после высокодозной химиотерапии с аутологичной трансплантацией стволовых клеток и указывают на позитивную роль М-МС в восстановлении кроветворения в раннем посттрансплантационном периоде у пациентов с ММ.</p></abstract><trans-abstract xml:lang="en"><p>Myeloid-derived suppressor cells (MDSCs) play an important role in the immune response regulation in many pathologies, primarily in malignant tumors, but their role in the hematopoietic stem cell engraftment and the hematopoietic recovery after high-dose chemotherapy and autologous stem cell transplantation remains practically unexplored. This study is aimed at studying the correlation between the number of MDSC subpopulations and blood parameters at the stage of hematopoietic recovery after high-dose chemotherapy and autologous hematopoietic stem cell transplantation in patients with multiple myeloma (MM). Circulating MDSCs were assessed at the stage of leukopenia recovery (absolute leukocyte count in peripheral blood (PB) &gt; 1 x 109/L) by flow cytometry. The number of transplanted CD34+CD45+ hematopoietic stem cells was 4.38 x 106/kg (IQR (3.1—5.6) x 106/kg). The duration of recovery from leukopenia varied from 8 to 18 days (Me 12 days). The number of MDSCs at the engraftment was not associated with the number of CD34+ cells/kg in the graft. The relative number of monocytic MDSCs (M-MDSCs, CD14+HLA-DRlow/-) directly correlated with the number of monocytes at the stage of recovery from leukopenia (R = 0.417, p = 0.002). Granulocytic MDSCs (PMN-MDSCs, Lin-HLA-DR-CD33+CD66b+) were characterized by an inverse correlation with the number of monocytes (R = -0.493, p = 0.0003) while the association with the absolute number of neutrophils was weak (R = 0.273, p = 0.048). The number of lymphocytes at the stage of recovery from leukopenia had an inverse correlation with PMN-MDSCs (R = -0.347, p = 0.014) and did not correlate with M-MDSCs. When analyzing the duration of leukopenia, an inverse correlation with this indicator was revealed for the percentage and absolute number of M-MDSCs (R = -0.347, p = 0.018 and R = -0.469, p = 0.0008, respectively). Multiple regression analysis showed dependence of the lymphopenia duration on the proportion of circulating M-MDSCs (p = 0.014) and the number of transplanted CD34+ cells/kg (p = 0.032). According to the data of multivariate analysis of variance, the number of transplanted CD34+ cells/kg and the number of M-MDSCs were significant factors for the duration of leukopenia. At the same time, such clinical parameters as the depth of response and minimal residual disease status before high-dose chemotherapy and hematopoietic stem cell transplantation, as well as the MM stage, did not affect the duration of hematopoietic recovery. Thus, the obtained results indicate the association of a higher number of M-MDSCs with a shorter duration of leukopenia after high-dose chemotherapy with autologous stem cell transplantation and indicate a positive role of M-MDSCs in hematopoietic recovery in the early post-transplant period in patients with MM.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>миелоидные супрессорные клетки</kwd><kwd>множественная миелома</kwd><kwd>трансплантация</kwd><kwd>гемопоэтические стволовые клетки</kwd><kwd>длительность лейкопении</kwd><kwd>раннее восстановление гемопоэза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>myeloid-derived suppressor cells</kwd><kwd>multiple myeloma</kwd><kwd>transplantation</kwd><kwd>hematopoietic stem cells</kwd><kwd>duration of leukopenia</kwd><kwd>early hematopoietic recovery</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study was funded by budget of Research Institute of Fundamental and Clinical Immunology (theme No. 122011800108-0).</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">Bronte V., Brandau S., Chen S.H., Colombo M.P., Frey A.B., Greten T.F., Mandruzzato S., Murray P.J., Ochoa A., Ostrand-Rosenberg S., Rodriguez P.C., Sica A., Umansky V., Vonderheide R.H., Gabrilovich D.I.
