摘  要:目的研究供受者HLA高分辨基因分型错配对非亲缘造血干细胞移植(HSCT)患者预后的影响。方法对来源于中华骨髓库随访登记的835对供受者资料进行回顾性分析,其中急性髓系白血病(AML)288例,急性淋巴细胞白血病(ALL)227例,慢性髓性白血病(CML)187例,骨髓增生异常综合征(MDS)52例,非霍奇金淋巴瘤(NHL)25例,再生障碍性贫血(AA)42例,地中海贫血14例。HLA.A、B、C、DRB1、DQB1高分辨基因分型采用DNA序列测定、序列特异性寡核苷酸探针和高分辨序列特异性引物分型方法。在835对供受者中HLA不相合473对,其中HLA1个等位基因错配159对,1个抗原错配125对,1个等位基因加1个抗原错配95对,2个等位基因错配29对,2个抗原错配20对,多个等位基因加抗原错配45对。随访截止到2011年3月。结果供受者HLA全相合总体生存(OS)率高于HLA不相合者(分别为79.83%和73.15%),差异无统计学意义(P〉0.05),但HLA的1个等位基因加1个抗原错配是影响HSCT患者OS、无病生存和移植相关死亡率的重要危险因素。不同疾病类型患者的OS率从高到低为地中海贫血、AA、CML、MDS、AML、NHL和ALL。HLA位点错配的受者OS率分别为DRB194.4%、DQB183.3%、B75.0%、A74.4%和C71.4%。1个等位基因错配的受者Os率从高到低为DRB1、C、A、B和DQB1。A、B、C位点错配的受者0s率和Ⅱ-Ⅳ度急性移植物抗宿主病(aGVHD)发生率与全相合受者比较差异均有统计学意义(P值均〈0.05)。优先考虑供受者HLA错配类型为B^*15:01/B^*15:05、DRB1^*12:01/DRB1^*12:02、C^*04:01/C^*03:04和DQB1^*03:02/DQB1^*03:03。供受者为B^*39:01/B^*39:05、C^*15:02/C^*14:02、C^*08:01/C^*03:04和C^*07:02/C^*15:02错配是影响移植患者OS率和aGVHD发生的危险因素。结论HLA-A、B、C、DRB1和DQB1Objective To study the impact of various human leukocyte antigen (HLA) high resolu- tion typing mismatching of donor-recipient pairs on prognosis of unrelated donor hematopoietic stem cell trans- plantation. Methods 835 donor-recipient pairs of CMDP data from 2005 to 2010 were analyzed retrospec- tively. HLA-A, B, C, DRB1 and DQB1 typing were performed using SBT, SSOP and SSP methods. The dis- eases involved in acute myeloid leukemia (AML) (n = 288), acuhe lymphoid leukemia(ALL) (n = 227), chronic myeloid leukemia(CML) ( n = 187 ), myelodysplastic syndrome (MDS) ( n = 52 ), non-Hodgkin' s lymphoma(NHL) (n = 25 ), aplastic anemia (AA) ( n = 42) and thalassemia ( n = 14 ). Of 835 donor-recipient pairs, 473 were not completely matched, 159 had a mismatch for a single allele, 125 had a mis- match for a single antigen, 95 had mismatch for both single allele and single antigen, 29 were mismatched at double allele, 20 at double antigen, 45 at multiple allele and antigen. The follow-up assessment was comple- ted before March 2011. Results HLA-matched pairs had higher overall survival (OS) than HLA-mismatched pairs (79.83% vs 73.15% ), but there was no statistically significant differences (P 〉 0.05). HLA mis- match for a single allele plus a single antigen was a significantly risk factor for OS, disease free survival (DFS) and transplant-related mortality(TRM). The OS from high to low in different diseases were thalasse- mia, AA, CML, MDS, AML, NHL, and ALL. OS of HLA locus mismatch were DRB1 (94.4%), DQB1 (83.3%), B(75% ) ,A(74.4% ) and C(71.4% ), respectively. OS of single allele mismatch at HLA locus from high to low were DRB1, C, A, B and DQB1. HLA-A, B, C locus mismatch were statistically significant- ly associated with lower OS and gradeⅡ - Ⅳ acute GVHD compared with HLA-matched pairs ( P 〈 0.05 ). The donor-recipient pairs with HLA-B^* 15: 01/B ^*15: 05, DRB1^* 12:01/DRB1 ^* 12: 02, C ^*
