- Abstract:
- BACKGROUND: Preventing graft vs. host disease (GvHD) after allogeneic hematopoietic stem cell transplant (allo-HSCT) is essential to improving the outcomes and quality of life of allo-HSCT recipients. Little is known about the trends and patterns of global GvHD prevention practices. Thus, the Worldwide Network for Blood & Marrow Transplantation global GvHD project aims to understand and describe the patterns of GvHD prevention and management worldwide. This article discusses GvHD prevention practices in the East Mediterranean (EM) region. MATERIALS AND METHODS: A questionnaire was distributed electronically to the EM region transplant centers and filled out by program directors or designees. Responses were received between December 2022 and June 2023. The questionnaire had 33 items, with 7 sections focusing on the different commonly used agents in GvHD practices (including calcineurin inhibitors, in vivo T-cell depletion, and methotrexate [MTX]). RESULTS: Thirty responses from 26 institutions were received from 11 countries in the EM region. All programs perform matched-related donor (MRD) transplants, 29 perform haploidentical transplants, and 19 perform matched unrelated donor (MUD) transplants. Cyclosporine (CsA) with MTX was the preferred regimen in both myeloablative (79%) and reduced intensity conditioning (50%). CsA was more widely used compared to tacrolimus (Tac) (93% vs. 57%). The duration of calcineurin inhibitor use before initiating taper in recipients with malignant and non-malignant disorders was similar between CsA and Tac. All programs reported routine monitoring of calcineurin inhibitor levels. Twenty-nine programs reported using MTX, administering it over 3-4 days post-HSCT. The use of different in vivo T-cell depletion therapies was commonly reported, particularly anti-thymocyte globulin (ATG) and post-transplant cyclophosphamide (PTCy). ATG use was reported by 77% and 79% of programs for MRD and MUD HCT, respectively. Additionally, most programs (97%) reported using PTCy mainly for haploidentical transplants. Among centers using PTCy, most programs reported using a dose of 50 mg/kg, and the most common schedule was Days +3 and +4. However, 12 programs reported using lower doses of 25-40 mg/kg or spaced-out schedules (Days +3 and +5). CONCLUSION: This study describes the different practices of GvHD prophylaxis in the EM region. Our results show that allo-HSCT centers in the EM regions utilize most standard-of-care agents, and most practices are in alignment with evidence-based guidelines.
