Abstract:
Objective: To compare the outcomes between haploidentical donor hematopoietic stem cell transplantation (haplo-HSCT) and matched-sibling donor transplantation (MSD-HSCT) for paroxysmal nocturnal hemoglobinuria (PNH) . Methods: The clinical data of 40 PNH patients received HSCT (haplo-HSCT=25, MSD-HSCT=15) from July 2007 to May 2018 were analyzed retrospectively to compare the outcomes between haplo-HSCT and MSD-HSCT groups. Results: There were no differences in terms of gender, age, patients of PNH-AA and median time from diagnosis to transplantation between the 2 groups (P>0.05) . The median values of absolute mononuclear cell counts and CD34+ cells infused were 10.74 (4.80-22.86) ×108/kg and 12.19 (5.14-17.25) ×108/kg (P=0.866) , 3.57 (0.68-7.80) ×106/kg and 4.00 (3.02-8.42) ×106/kg (P=0.151) respectively, in haplo-HSCT and MSD-HSCT groups. All patients attained complete engraftment, no patient occurred graft failure. The median durations for myeloid and platelet engraftment were 12 (range, 9-26) and 11 (range, 7-15) days (P=0.065) , 19 (range, 11-75) and 13 (range, 11-25) days (P=0.027) respectively, in haplo-HSCT and MSD-HSCT groups. During a median follow-up of 26 (4-65) months in haplo-HSCT and 36 (4-132) months in MSD-HSCT groups (P=0.294) , the incidences of grade Ⅰ-Ⅳ acute graft-versus-host disease (aGVHD) were 32.0% and 20.0% (P=0.343) , grade Ⅱ-Ⅳ aGVHD were 16.0%, 13.3% (P=0.759) , chronic GVHD were 30.7% and 24.6% (P=0.418) , moderate-severe chronic GVHD were 12.7% and 7.1% (P=0.522) respectively, in haplo-HSCT and MSD-HSCT groups. The incidences of infection were 32.0% (8/25) and 26.7% (4/15) (P=1.000) respectively, in haplo-HSCT and MSD-HSCT groups. No patients occurred early death and relapse. Three-year estimated overall survival (OS) were (86.5±7.3) % and (93.3 ±6.4) % (P=0.520) , GVHD-free and failure-free survival (GFFS) were (78.3±8.6) % and (92.9±6.9) % (P=0.250) respectively, in haplo-HSCT and MSD-HSCT groups. Conclusion: The preliminary results indicated that haplo-HSCT was a feasible choice for PNH with favorable outcomes, haplo-HSCT and MSD-HSCT produced similar therapeutic efficacy.
