摘 要:目的探讨无关供者异基因造血干细胞移植(allo-HSCT)患者及其干细胞供者的肿瘤坏死因子(TNF)单核苷酸多态性(SNP)与急性移植物抗宿主病(aGVHD)之间的关系。方法回顾性分析浙江大学医学院附属第一医院移植中心接受无关供者allo-HSCT患者及其供者,共76对,采用多重单碱基延伸SNP分型技术检测TNF基因5个位点的SNP(TNFα-238、TNFα-857、TNFα-863、TNFα-1031、TNFβ+252),分析与aGVHD的发生风险、临床严重程度之间的关系。结果在23例发生Ⅱ-Ⅳ度aGVHD患者中,其干细胞供者基因型TNFα-857CC的频率(91.3%)高于基因型cT(8.7%)(P=0.039);TNF[3+252(A/G)位点未检出AA基因型,19例患者为GA基因型(82.6%),4例患者为GG基因型(17.4%),3组之间比较差异有统计学意义(P=0.006)。而患者与干细胞供者TNFα-238(G/A)、TNFα-863(C/A)和TNFα-1031(T/C)位点的基因多态性均未发现与aGVHD的发生风险相关。结论干细胞供者TNFα-857CC基因型与Ⅱ~Ⅳ度aGVHD的发生密切相关,而TNFβ+252为AA基因型的患者不易发生Ⅱ~Ⅳ度aGVHD。Objective To explore the relationship between tumor necrosis factor (TNF) gene polymorphisms in donors and recipients and the incidence and severity of acute graft-versus-host diseases (aGVHD) after unrelated allogeneie hematopoietic stem cell transplantation (allo-HSCT) . Methods Single nucleotide polymorphisms ( SNPs ) of TNFα-238 ( G/A), TNFα-857 ( C/T), TNFα-863 ( C/A ), TNFα-1031 (T/C), TNFβ + 252(A/G) were analyzed by Multiplex SNaPshot analysis in 76 pairs of donors and recipients. Results Transplantation involving donors with TNFα-857 CC genotype resulted in a higher incidence of grade Ⅱ -Ⅳ aGVHD than donors with CT genotype (91.3% vs 8. 7% , P =0. 039). In the 23 patients with grade Ⅱ-Ⅳ aGVHD, no patients had TNFβ+ 252 AA genotype, 19 (82. 6% ) had GA genotype and 4 ( 17.4% ) had GG genotype. There was a significant difference in the distribution pattern of the TNFα + 252 (AA, GA and GG) genotypes in these patients (P = 0. 03 ). There was no significant association of TNFα-238 ( G/A), TNFα-863 (C/A) and TNFα-1031 (T/C) polymorphisms with the risk of aGVHD. Conclusion These results suggest donor TNFα-857 CC genotype is related to a higher incidence of grade Ⅱ -Ⅳ aGVHD, and patients with TNFα +252 AA genotype have protection against the risk of grade Ⅱ-Ⅳ aGVHD.
