Development of acute GVHD is a negative factor for outcomes. Using «novel» strategies for drug prophylaxis, such as posttransplant cyclophosphamide (PtCy) allows to decrease the GVHD risk. The aim of this study: to assess efficiency of PtCy as a prophylaxis aGVHDin the patients with non-malignant diseases of hematopoiesis and inherited syndromes. 97 patients with non-malignant blood disorders and metabolic diseases received 118 underwent allo-HSCT at the R. Gorbacheva Memorial Institute of Children Oncology and Transplantation. The aGVHD prophylaxis in 89 cases was performed by a standard schedule (with calcineurin inhibitors). 29 patients were treated according to PtCy regimen, at a dose of 50 mg/kg at days +3, +4. Cumulative incidence (CI) of aGVHD comprised 32%. Patients treated with PtCy exhibited lower rates of this condition compared to the group with standard prophylaxis schedule (26 vs 47%, р = 0.05). CI of skin aGVHD was also less common in the PtCy group (23 vs 45%, р = 0.046); gastrointestinal aGVHD was observed at equal rates in the both groups. Stem cell engraftment after nonmyeloablative conditioning in HSCT patients with subsequent PtCy administration proved to be sufficiently weaker compared to other patients (86 vs 50%, р = 0.004). Conclusions: aGVHD prophylaxis based on posttransplant PtCy is an efficient method which may decrease aGVHD risk. However, one should take into account a higher non-engraftment rate as a potential hazard of HSCT when using non-myeloablative conditioning regimens and PtCy-based GVHD prophylaxis.</p></abstract><trans-abstract xml:lang="ru"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>allogeneic hematopoietic stem cell transplantation</kwd><kwd>non-malignant disorders</kwd><kwd>acute graft-versus-host disease</kwd><kwd>posttransplant cyclophosphamide treatment</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>аллогенная трансплантация гемопоэтических стволовых клеток</kwd><kwd>острая реакция «трансплантат против хозяина»</kwd><kwd>посттрансплантационноый циклофосфамид</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Passweg J.R., Baldomero H., Bader P.,European Society for Blood and Marrow Transplantation (EBMT).
