摘  要:目的探讨供、受者白细胞介素10(IL-10)基因启动子区单核苷酸基因多态性(SNP)对恶性血液病患者HLA匹配同胞供者异基因造血干细胞移植(allo—HSCT)疗效的影响。方法采用序列特异性引物聚合酶链式反应检测77例供、受者IL-10基因-1082A/G、-819T/C、-592C/A位点的SNP,探讨供、受者不同基因型与受者移植疗效的相关性。结果ATA/ATA纯合子型与非ATA/ATA纯合子受者各有33例和44例,两者Ⅱ-Ⅳ度急性移植物抗宿主病(aGVHD)的发生率分别为6.1%和25.0%(P〈0.05);移植后预期5年移植相关死亡(TRM)率分别为(10.7±5.9)%和(29.7±5.2)%(P〈0.05);5年无病生存(DFS)率分别为(81.8±6.7)%和(56.8±7.5)%(P〈0.05)。ATA/ATA纯合子型与非ATA/ATA纯合子受者间慢性移植物抗宿主病(cGVHD)发生率和复发率的差异无统计学意义(P〉O.05)。供者为ATA/ATA纯合子和非ATA/ATA纯合子型者各有37例和40例,其相应受者Ⅱ-Ⅳ度aGVHD发生率、广泛型cGVHD发生率、5年累积复发率、TRM率、DFS率的差异均无统计学意义(P〉0.05)。多因素分析显示,受者非ATA/ATA纯合子型和原发病为高危的受者为降低DFS的独立危险因素(危险度=2.911,P=0.029;危险度=2.686,P=0.027)。结论在HLA相合同胞供者allo-HSCT中,与非IL-10ATA/ATA基因型受者相比较,ATA/ATA基因型受者移植后Ⅱ-Ⅳ度aGVHD发生率和TRM率显著降低,其DFS率也较高。Objective To explore the impact of IL-10 gene polymorphisms on the outcome in HLA matched sibling hematopoietic stem cell transplantation (HSCT). Methods PCR-sequence- specific primer (PCR-SSP) assay was used to analyze the SNP of IL-10 in 77 recipient and donor pairs:-1082 A/G,-819 T/C,-592 C/A. Results IL-10 ATA/ATA (-1082,-819,-592) genotype in recipients significantly decreased the incidence of grade Ⅱ-Ⅳ acute graft-vursus-host disease (aGVHD) (6. 1% vs. 25.0%,P〈0. 05), reduced 5-year transplant-related mortality (TRM) (10. 7% ± 5.9% vs. 29. 7% ± 5. 2% ,P〈0. 05) and increased disease free survival (DFS) (81.8% ±6. 7% vs. 56. 8% ± 7. 5% ,P〈0. 05). With regard to the donor genotype, the incidence of grade Ⅱ-Ⅳ aGVHD, extensive chronic GVHD, 5-year TRM and DFS had no signicant difference between IL-10 ATA/ATA and non ATA/ATA subgroup. Multivariable analysis also revealed that IL-10 non-ATA/ATA genotype in recipients and high-risk status of disease were two independent risk factors for DFS (HR =2.911,P = 0.029; HR = 2.686, P = 0.027). Conclusion In HLA-matched sibling HSCT, the presence of recipient IL-10 ATA/ATA significantly decreased the incidence of grade Ⅱ-Ⅳ aGVHD and TRM, and increased DFS.
