OBJECTIVETo evaluate the efficacy of HLA- haploidentical donor hematopoietic transplantation (Haplo- HSCT)for severe aplastic anemia (SAA)by compared with the same period of unrelated donor transplantation (UD- HSCT).
METHODSOf a cohort of 50 SAA patients between September 2012 and July 2014, 26 patients underwent UD- HSCT and 24 patients Haplo- HSCT.
RESULTSOS rate was 91.3% with a median follow-up of 9 (2-26)months. According to transplant type, there was no significant difference between UD- and Haplo-HSCT (96.1%vs 86.0%,P=0.30). 3 of 50 (6%)patients had primary engraft failure. Haplo- HSCT developed higher significantly incidence of Ⅱ- Ⅳ aGVHD (37.5%vs 3.83%,P=0.003)and cGVHD (37.5%vs 15.3%,P=0.030)than UD-HSCT. Haplo-HSCT also had significantly higher incidences of CMV viremia (78.2%vs 46.1%,P=0.005)and EBV viremia (43.1%vs 16.0%,P=0.040), respectively than UD-HSCT. But the incidences of hemorrhagic cystitis were similar between two transplant types (39.1%vs 23.0%,P=0.120).
CONCLUSIONThis study showed favorable outcome of Haplo-HSCT for SAA, which was comparable with UD-HSCT.
