Мобилизация гемопоэтических стволовых клеток (ГСК) препаратом плериксафор (Мозобаил) в сочетании с колониестимулирующим фактором у пациентов с предшествующими неудачами получения трансплантата для аутотрансплантации ГСК

У всех пациентов до введения плериксафора было отмечено низкое или промежуточное количество CD34+-клеток в 1 мкл периферической крови. У пациентки с неудачной мобилизацией с помощью плериксафора было отмечено наименьшее количество CD34+-клеток в 1 мкл периферической крови как до, так и после введения плериксафора. У 9 пациентов содержание CD34+-клеток после стимуляции плериксафором увеличилось в 2–4 раза. Существенных побочных явлений, связанных с введением препарата плериксафор, не было. Таким образом, наш первый опыт применения плериксафора показал его эффективность и хорошую переносимость.
Ключевые слова: мобилизация гемопоэтических стволовых клеток, аутотрансплантация гемопоэтических стволовых клеток, плериксафор.

AutoHSCT is an effective treatment for patients with relapsed and refractory lymphomas, multiple myeloma, some solid tumors. For a successful transplantation it is necessary to obtain an adequate quality and quantity transplant. Due to the heavy pretreatment this category of patients receiving a transplant can be a serious problem, which can be solved with the use of the new mobilizing agent inhibitor CXCR4 – plerixafor. In our study, 10 patients, of which 7 were confirmed as «poor mobilizers» were stimulated with colony stimulating factor, together with a plerixafor dose 0,24 mg/kg body weight on day 5 and 6 of stimulation. In 9 of the 10 patients we had obtained an adequate transplant. In all patients before the administration of plerixafor low or intermediate number of CD34+ cells per microliter of peripheral blood was obtained. The patient failed to mobilize with the use of plerixafor mentioned the smallest number of CD34+ cells per microliter in peripheral blood both before and after administration of plerixafor. In 9 patients, the content of CD34+ cells after stimulation with plerixafor increased by 2–4 times.
Key words: hematopoietic stem cell mobilization, autologous hematopoietic stem cell transplantation, plerixafor.
