摘 要:目的研究造血干细胞移植(HSCT)后人类疱疹病毒6型(HHV-6)活化与急性移植物抗宿主病(aGVHD)的相关性。方法移植前以及移植后每周1次连续采集72例患者的外周血样本,采用筑巢式聚合酶链反应扩增 HHV-6基因序列,Hind Ⅲ酶切对 HHV-6基因分型。结果 72例患者移植后45例(62.5%)检出 HHV-6血症,中位时间为第14(7~63)天;40例(55.6%)患者发生Ⅰ~Ⅳ度 aGVHD,中位时间第26(9~73)天。HHV-6血症发生的中位时间显著早于Ⅰ~Ⅳ度 aGVHD 发生时间(P=0.018)。Ⅰ~Ⅳ度 aGVHD 累积发生率在 HHV-6阳性组为68.9%(45例中31例),显著高于HHV-6阴性组的33.3%(27例中9例)(P=0.003)。Ⅱ~Ⅳ度 aGVHD 累积发生率 HHV-6阳性组为35.6%,显著高于 HHV-6阴性组的14.8%(P=0.027)。移植后Ⅰ~Ⅳ度 aGVHD 的发生率在巨细胞病毒(CMV)和 HHV-6共感染(CMV^+/HHV-6^+)组、CMV 阳性 HHV-6阴性(CMV^+/HHV-6)组、CMV阴性 HHV-6阳性(CMV-/HHV-6^+)组和 CMV 与 HHV-6均阴性(CMV^-/HHV-6^-)组分别为78.9%,55.6%,14.3%和22.25%,差异有统计学意义(P=0.0001)。Ⅱ~Ⅳ度 aGVHD 累积发生率在 CMV^+/HHV-6^+、CMV^+/HHV-6^-、CMV^-/HHV-6^+和 CMV^-/HHV-6^-组分别为42.1%,22.2%,0% 和11.1%,差异有统计学意义(P=0.008)。结论 HSCT 后 HHV-6感染以及 HHV-6和 CMV 共感染与 aGVHD发生率存在显著相关性。Objective To study the potential relationship between HHV-6 activation and acute graftversus-host disease (aGVHD) after allogeneic hematopoietic cell transplantation (HSCT). Methods Peripheral blood samples were collected before and weekly after HSCT from 72 consecutive recipients. HHV-6 DNAemia was monitored by nested polymerase chain reaction(PCR). The genotypes of HHV-6 were identified by Hind Ⅲ restriction assay. Results Of the 72 patients, HHV-6 DNAemia were detected in 45 (62.5%) on a median of day 14(range, 7 -63 days) after HSCT. Grade Ⅰ-Ⅳ aGHVD occurred in 40 (55.6%) on a median of day 26(range, 9-73 days). The median onset time of HHV-6 DNAemia was significantly earlier than that of aGHVD (P=0.018 ). Compared with that in HHV-6 DNAemia negative [ HHV- 6(-)] patients, the cumulative incidence of grade Ⅰ-ⅣaGHVD was higher (68.9% vs. 33.3% , P=0.003) in HHV-6( + ) patients. Cumulative incidence of grade Ⅱ-ⅣaGVHD in HHV-6( + ) cohort was also higher than that in HHV-6( - ) cohort (35.6% vs 14.8% , P = 0. 027). Cumulative incidence of grade Ⅰ-Ⅳ aGVHD was higher in patients with both HHV-6 and CMV positive ( CMV +/HHV-6 + ) than in those with either CMV (CMV^+/HHV-6^- ) or HHV-6 positive (CMV^-/HHV-6^+ ) and neither of them positive ( CMV^-/HHV-6^- ) [ 78.9% (30/38), 55.6% ( 5/9 ), 14.3% ( 1/7 ) and 22.2% ( 4/18 ), respectively, P = 0.0001 ]. Cumulative incidence of grade Ⅱ-Ⅳ aGVHD in CMV^+/HHV-6^+ group was also higher than that in CMV^-/HHV-6^-, CMV^-/HHV-6^+ and CMV^-/HHV-6^- groups [ 42.1% ( 16/38 ), 22.2% ( 2/9 ), 0% (0/7) and 11.1% ( 2/18 ) , P=0.0081. Conclusions Patients with HHV-6 activation or HHV-6/CMV confection maybe involved in the occurrence of aGVHD after HSCT.
