Here, we report a case of a successful allogeneic hematopoietic stem cell transplantation performed in a pediatric patient with B-cell acute lymphoblastic leukemia who developed persistent granulocyte colony-stimulating factor refractory chemotherapy-induced myelosuppression and severe sepsis. Following the procedure, the patient achieved hematopoietic recovery with subsequent resolution of the infection and was able to resume treatment. The patient's parents gave consent to the use of their child's data, including photographs, for research purposes and in publications.</p></abstract><trans-abstract xml:lang="ru"><p>Проведение аллогенной трансплантации гемопоэтических стволовых клеток у пациентов с тяжелыми инфекционными процессами сопряжено с высокой смертностью на фоне прогрессии инфекции и недостаточности трансплантата. В данной статье представлен опыт успешной терапии по восстановлению кроветворения аллогенными гемопоэтическими стволовыми клетками у пациента с B-линейным острым лимфобластным лейкозом, находящегося в состоянии длительной химиоиндуцированной миелосупрессии, рефрактерной к терапии колониестимулирующим фактором, осложнившейся тяжелым септическим процессом. Благодаря восстановлению кроветворной функции инфекционный процесс был санирован и пациент смог продолжить лечение. Родители пациента дали согласие на использование информации, в том числе фотографий ребенка, в научных исследованиях и публикациях.</p></trans-abstract><kwd-group xml:lang="en"><kwd>allogeneic hematopoietic stem cell transplantation</kwd><kwd>bone marrow suppression</kwd><kwd>sepsis</kwd><kwd>acute lymphoblastic leukemia</kwd><kwd>pediatric oncology</kwd><kwd>conditioning</kwd><kwd>graft-versus-host disease prevention</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>аллогенная трансплантация гемопоэтических стволовых клеток</kwd><kwd>аплазия кроветворения</kwd><kwd>сепсис</kwd><kwd>острый лимфобластный лейкоз</kwd><kwd>детская онкология</kwd><kwd>кондиционирование</kwd><kwd>профилактика реакции «трансплантат против хозяина»</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Не указан</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
