摘　　要：目的 探讨急性髓系白血病（AML）患者异基因造血干细胞移植（allo-HSCT）后巨细胞病毒（CMV）感染对白血病复发的影响.方法 回顾性分析2005年1月至2014年1月中山大学附属中山医院血液内科接受allo-HSCT的62例AML患者（除外急性早幼粒细胞性白血病）,观察患者移植后白血病复发与CMV感染及供受者临床特征的关系.结果 单因素分析显示,初诊时白细胞＞100×10^9/L、疾病高危、移植后环孢素浓度低于200 μg/L的患者复发率高,而移植后CMV阳性及慢性GVHD患者复发率低;Cox多因素分析显示,疾病高危（RR=3.296,95％ CI：1.274～8.530,P＝0.014）、无慢性GVHD（RR =0.167,95％ CI：0.042～0.668,P=0.011）及CMV阴性（RR＝0.285,95％CI：0.084 ～0.973,P=0.045）是移植后复发的独立危险因素.结论 AML患者allo-HSCT后CMV血症是影响复发的有利因素之一.Objective To explore the relationship between cytomegalovirus （CMV） infection and risk factors for relapsing patients with acute myeloid leukemia（AML） （non-acute promyelocytic leukemia） after hematopoietic stem cell transplantation （HSCT）.Methods A total of 62 allo-HSCT patients from January 2005 to January 2014 were enrolled and analyzed retrospectively.And the clinical characteristics of donors and recipients and post-transplantation relapse were recorded.Results Single factor analysis indicated that there were 5 risk factors correlated with disease relapse （P 〈0.05）.Leucocytosis （〉 100 × 10^9/L）,high-risk AML and cyclosporine A concentration under 200 μg/L were correlated with high relapsing rates while CMV reaction and chronic graft versus host disease had a low relapsing rate.Cox regression analysis revealed that high-risk AML （RR =3.296,95% CI：1.274-8.530,P =0.014）,CMV negativity （RR =0.285,95 % CI：0.084-0.973,P =0.045） and non-chronic GVHD （RR =0.167,95 % CI：0.042-0.668,P =0.011） were major risk factors of relapse.Conclusion Human CMV viremia after allo-HSCT has a decreased relapsing risk in patients with AML.
