摘　　要：为了研究ABO血型不合异基因造血干细胞移植(allo-HSCT)后并发纯红细胞再生障碍(pure red cell aplasia,PRCA)的发病情况及危险因素,对本医院以往血型不合异基因造血干细胞移植进行回顾性分析,探讨移植后患者PRCA的发病危险因素。研究结果表明,72例ABO血型不合allo-HSCT患者中,4例发生PRCA,其中A供O3例,A供B1例。PRCA的发生不影响急性移植物抗宿主病(GVHD)或巨细胞病毒(CMV)感染的发生。PRCA患者红系恢复的时间显著长于未PRCA发生患者。结论:PRCA是ABO血型不合移植的主要并发症。A供O可能是ABO血型不合allo-HSCT后并发PRCA的危险因素。The objectives of study was to investigate the clinical characteristics and risk factors of pure red cell apalsia （PRCA） following ABO-incompatible allogeneic hematopoietic stem cell transplantation （allo-HSCT）. The clinical data of 72 patients receiving ABO-incompatible allo-HSCT were collected and retrospectively studied. The clinical parameters including sex, age, granulocyte engraftment time and blood transfusion were analyzed for the exploration of risk factors resulting in development of PRCA. The results indicated that 4 out of 72 patients receiving ABO-incompatible allogeneic hematopoietic stem cell transplantation developed PRCA, 3 cases out of these patients were ABO-major incompatible, 1 case was Bi-direction incompatible, no any eftect of PRCA was observed on incidence of GVHD and CMV infection. In conclusion, PRCA is a major complication of patients receiving ABO-incompatible allo- HSCT, while ABO blood group of O/A in recipient/donor pair may be the major high risk factor for PRCA after ABO- mismatched allo-HSCT.
