Herpes simplex virus (HSV)-1/2 can still be reactivated after allogeneic haematopoietic stem cell transplantation (allo-HSCT) even when the prophylactic acyclovir is used. However, the risk factors for HSV-1/2 viremia and the clinical outcomes following unmanipulated haploidentical HSCT remain unknown.
Nineteen patients with HSV-1/2 viremia and fifty-seven patients without HSV-1/2 viremia which were selected using the case-pair method after undergoing haploidentical HSCT were enrolled. We analysed the risk factors for HSV-1/2 viremia and compared the clinical outcomes between the two groups.
The risk factors for HSV-1/2 viremia included HLA disparity ≥2 loci (p=0.049) and cytomegalovirus (CMV) reactivation (p=0.028). The incidences of platelet engraftment, oral mucositis and severe haemorrhagic cystitis (HC) in patients with and without HSV-1/2 viremia were 77% and 94% (p=0.003), 78% and 13% (p=0.000), and 25% and 6% (p=0.04), respectively. Moreover, the median time to platelet engraftment in patients with and without HSV-1/2 viremia was +25days (range, +11-+80) and +17days (range, +8-+67) (p=0.004), respectively. According to the multivariate analyses, HSV-1/2 viremia was associated with delayed platelet engraftment (p=0.038), a higher incidence of oral mucositis (p=0.000) and severe HC (p=0.038). However, HSV-1/2 viremia was not associated with non-relapse mortality (34.0% vs. 31.5%, p=0.26), leukaemia-free survival (60.9% vs. 57.9%, p=0.46) and overall survival (61.2% vs. 60.7%, p=0.37).
Based on our study results, we recommend that HSV-1/2 PCR should be performed upon clinical suspicion of HSV-1/2 infection.
即使使用预防性阿昔洛韦,异基因造血干细胞移植(allo-HSCT)后单纯疱疹病毒 1/2(HSV-1/2)仍可再激活。然而,未处理的单倍体相合 HSCT 后 HSV-1/2 血症的危险因素和临床结局仍不清楚。
我们选择了 19 例 HSV-1/2 血症患者和 57 例无 HSV-1/2 血症患者进行配对分析,这些患者均接受了单倍体相合 HSCT。我们分析了 HSV-1/2 血症的危险因素,并比较了两组患者的临床结局。
HSV-1/2 血症的危险因素包括 HLA 错配≥2 个位点(p=0.049)和巨细胞病毒(CMV)再激活(p=0.028)。有和无 HSV-1/2 血症的患者血小板植入、口腔粘膜炎和严重出血性膀胱炎(HC)的发生率分别为 77%和 94%(p=0.003)、78%和 13%(p=0.000)和 25%和 6%(p=0.04)。此外,有和无 HSV-1/2 血症的患者血小板植入的中位时间分别为+25 天(范围,+11-+80)和+17 天(范围,+8-+67)(p=0.004)。根据多变量分析,HSV-1/2 血症与血小板植入延迟相关(p=0.038),与口腔粘膜炎发生率较高(p=0.000)和严重 HC 相关(p=0.038)。然而,HSV-1/2 血症与非复发死亡率(34.0% vs. 31.5%,p=0.26)、白血病无病生存率(60.9% vs. 57.9%,p=0.46)和总生存率(61.2% vs. 60.7%,p=0.37)无关。
根据我们的研究结果,我们建议在怀疑 HSV-1/2 感染时应进行 HSV-1/2 PCR。
