Post-Transplant Cyclophosphamide-Based Prophylaxis and Its Impact on Infectious Complications and Immune Reconstitution According to Donor Type.

ABSTRACT: Background/Objectives: This study evaluated infectious complications and immune reconstitution in 253 adults undergoing peripheral blood allogeneic hematopoietic cell transplantation (allo-HCT) with post-transplant cyclophosphamide (PTCY)-based GVHD prophylaxis. Methods: Patients received grafts from HLA-matched donors (47.4%), mismatched unrelated donors (MMUD, 33.2%), or haploidentical donors (19.4%). Results: The estimated 2-year non-relapse mortality (NRM) was 11.8%, 26.4%, and 22.4%, respectively (p = 0.0528). The cumulative incidence (Cum.Inc) of acute and chronic GVHD, immunosuppression duration, and post-transplant outcomes were similar across donor types. The day +30 Cum.Inc of bacterial bloodstream infections (BSI) tended to be higher in HLA-matched tr
