Abstract

Although messenger ribonucleic acid vaccines are substantially effective toward SARS-CoV-2 infection, patients with hematologic malignancies are still prone to the virus. Herein, we report a fatal case of breakthrough SARS-CoV-2 Delta variant infection in a patient with mucosa-associated lymphoid tissue lymphoma with remission by bendamustine-rituximab (BR) therapy completed a year ago. The serologic study revealed impaired responsiveness toward vaccines and prolonged high viral load after infection. BR therapy seemingly induced an immune escape. Prevention and treatment strategies for such vulnerable patients should be clarified immediately.

摘要

尽管信使核糖核酸疫苗对 SARS-CoV-2 感染具有显著效果,但血液系统恶性肿瘤患者仍易感染该病毒。在此,我们报告了一例黏膜相关淋巴组织淋巴瘤患者在完成一年前苯达莫司汀-利妥昔单抗(BR)治疗后突破性感染 SARS-CoV-2 Delta 变异株的致死病例。血清学研究显示疫苗反应受损和感染后病毒载量持续高。BR 治疗似乎诱导了免疫逃逸。应立即明确针对此类脆弱患者的预防和治疗策略。
