Abstract:
Objective To study the feasibility of HLA non-identical allogeneic peripheral blood hematopoietic stem cell transplantation (allo-PBHSCT) for the treatment of patients with severe aplastic anemia (SAA). Methods Four patients with SAA received non-identical allo-PBHSCT from HLA one or three loci mismatched related donors. Donors were given G-CSF 5?g/(kg?d) for 5 days, then PBSC were harvested on days 4 and 5. Prime regimen consisted of fludarbine, CTX, ATG and TBI. Combination of CsA, MTX, MMF and Simulect (CD25 monoclonal antibody) were used for GVHD prophylaxis. Results Engraft was achieved in all patients. The median days of neutrophil exceeding 0.5?109/L and platelet exceeding 20?109/L were 15.3 days (range 14~16 days) and 17.5 days (range 16~19 days), respectively. In the 14-month median follow-up duration, only one of four patients developed grade Ⅱ aGVHD, and one patient died of systemic candidiasis, the other three were alive in disease-free condition. Conclusion HLA non-identical allo-PBHSCT was well tolerated by patients with SAA, and it provided rapid and sustained engraftment without increase in incidence of GVHD.
