摘要:

目的 探讨多发性骨髓瘤(MM)患者自体造血干细胞移植(ASCT)期间感染新型冠状病毒(SARS-CoV-2)的干预策略,并分析ASCT后免疫重建对抑制过度炎症反应的潜在调控作用。方法 报告2例MM患者(IgA-λ型、IgG-κ型)在ASCT期间感染SARS-CoV-2的临床病例,并结合相关文献进行分析。结果 2例患者经早期启动抗病毒、抗菌药物及积极的造血支持治疗后,中性粒细胞恢复与病毒清除呈现同步趋势(病例1:感染后10 d;病例2:感染后3 d)。值得注意的是,炎症标志物(C反应蛋白、降钙素原)在整个病程中持续维持于正常范围,未见重症进展及细胞因子风暴的发生。结论 尽管ASCT期间感染SARS-CoV-2风险较低,但严格的防护措施和早期、多维度的干预策略至关重要。同时,ASCT后免疫重建初期特有的淋巴细胞耗竭状态可能通过抑制IL-6、TNF-α等关键促炎因子的释放,联合固有免疫系统的时序性优先重建,协同降低了细胞因子风暴的风险,为临床干预提供了关键的时间窗。

Abstract:

Objective To investigate the intervention strategies for multiple myeloma (MM) patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during autologous hematopoietic stem cell transplantation (ASCT) and to analyze the potential regulatory role of post-ASCT immune reconstitution in suppressing excessive inflammatory responses. Methods We report two clinical cases of MM patients (with IgA-λ and IgG-κ types) who contracted SARS-CoV-2 during ASCT,supplemented by a review of relevant literature. Results Following the early initiation of antiviral and antibacterial agents alongside aggressive supportive care,neutrophil recovery coincided with viral clearance in both cases (Case 1: at 10 days post-infection; Case 2: at 3 days post-infection). Notably,inflammatory markers (C-reactive protein and procalcitonin) remained within reference ranges throughout the clinical course,with no progression to severe disease and no evidence of cytokine storm. Conclusion Although the risk of SARS-CoV-2 infection during ASCT is relatively low,strict protective measures and early,multidimensional intervention strategies are crucial. Furthermore,the unique lymphocyte-depleted state during early immune reconstitution post-ASCT may suppress the release of key proinflammatory cytokines such as IL-6 and TNF-α. This mechanism,coupled with the temporally prioritized reconstitution of the innate immune system,may synergistically reduce the risk of a cytokine storm,providing a critical window for clinical intervention.
