Patients receiving a hematopoietic cell transplant are thought to be at increased risk of infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and coronavirus infectious disease 2019. Transplant activities at our center continue, and notably, no patient has been infected with SARS-CoV-2. Indeed, social distancing, masking, and education for patients and donors are major pillars of prevention. We recommend potential transplant recipients and donors to be tested for SARS-CoV-2 with qRT-PCR, serum antibody detection, and a lung CT scan pretransplant. If possible, stem cells from HLA-matched unrelated donors by local processing laboratories should be cryopreserved and shipped before initiating pretransplant conditioning. An alternative HLA-haplotype-matched related donor should be identified and evaluated as a backup. The interval immediately after discharge is the time of greatest risk for SARS-CoV-2 infection because of travel and exposure to infected persons. We recommend self-isolation and minimal contact with family members. Nonessential clinic visits should be deferred or substituted with telemedicine consultations if possible. These recommendations are based on our experience at a major transplant center in China. Although some recommendations are evidence based, other recommendations are not and warrant validation in controlled trials.
接受造血细胞移植的患者被认为感染严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)和 2019 年冠状病毒病的风险增加。我们中心的移植活动仍在继续,值得注意的是,没有患者感染 SARS-CoV-2。实际上,社交距离、戴口罩和对患者及供者进行教育是预防的主要支柱。我们建议潜在的移植受者和供者在移植前通过 qRT-PCR、血清抗体检测和肺部 CT 扫描检测 SARS-CoV-2。如果可能,应通过当地处理实验室冷冻保存和运输 HLA 匹配的无关供者的干细胞,然后再开始移植前预处理。应确定并评估另一个 HLA 单倍型匹配的相关供者作为备份。由于旅行和接触感染者,出院后立即是感染 SARS-CoV-2 的风险最大的时期。我们建议自我隔离并尽量减少与家庭成员的接触。如果可能,应推迟非必要的门诊就诊或用远程医疗咨询代替。这些建议是基于我们在中国的一家主要移植中心的经验。虽然一些建议是基于证据的,但其他建议不是,需要在对照试验中验证。
