Аннотация
BACKGROUND: Hematopoietic stem cell transplantation (HSCT) is potentially curative for severe aplastic anemia (SAA). Graft failure (GF) remains a life-threatening complication after HSCT. Preexisting anti-HLA antibodies, especially HLA-specific antibodies (DSA), have been demonstrated as a risk of GF.
CASE PRESENTATION: This report describes a woman with acquired SAA who presented with anti-HLA antibodies and GF. After the treatment of anti-HLA antibodies, engraftment was achieved through a second alternative donor HSCT. This work complied with the Declaration of Helsinki and the Declaration of Istanbul.
CONCLUSIONS: Based on our experience in treating this case, we hold that the presence of preoperative anti-HLA antibodies could discount the efficacy of HSCT and anti-HLA antibody screening should be performed before HSCT. Additionally, a second HSCT is feasible to prolong survival.
