Parvovirus B19 (PVB19) infection has been implicated in allograft failure or dysfunction in solid organ transplantation (SOT) and allogeneic hematopoietic stem cell transplantation (allo-HSCT), but the literature is limited.
Two pediatric patients were diagnosed with PVB19 infection around the time of allo-HSCT graft failure. Both cases were secondary graft failure and required second allo-HSCT.
There are many risk factors and potential confounders in determining the exact etiology of graft failure after allo-HSCT. These two cases highlight the importance of including PVB19 in the diagnostic evaluation for graft failure. PVB19 infection may be an important risk factor for allo-HSCT graft failure.
细小病毒 B19(PVB19)感染已被牵连入实体器官移植(SOT)和异基因造血干细胞移植(allo-HSCT)中的移植物失败或功能障碍,但文献有限。
两名儿科患者在 allo-HSCT 移植物失败时被诊断为 PVB19 感染。这两个病例都是二次移植物失败,需要进行第二次 allo-HSCT。
在确定 allo-HSCT 后移植物失败的确切病因时,存在许多风险因素和潜在混杂因素。这两个病例强调了在诊断评估移植物失败时将 PVB19 包括在内的重要性。PVB19 感染可能是 allo-HSCT 移植物失败的一个重要危险因素。
