Background/Aim: Anti-CD20-depleting monoclonal antibodies predispose patients to the development of severe disease of SARS-CoV-2 infection. These antibodies are given as backbone or maintenance therapy in patients with hematological malignancies and rheumatology diseases, inducing effective B-cell depletion along with antibodydependent cell-mediated cytotoxicity (ADCC) and disrupting infection-protective antibody responses. Case Report: We describe two cases of prolonged SARS-CoV-2 infection with common features, in two patients receiving anti-CD20 therapies, the first for chronic lymphocytic leukemia (CLL) and the second for rheumatoid arthritis (RA). For CLL patient, despite administration of antiviral therapy, signs and symptoms of SARS-CoV-2 infection persisted for 43 days, with resolution and lymphocyte recovery from day 33. For RA patient, despite administration of two courses of antiviral therapy, signs and symptoms of SARS-CoV-2 infection persisted for 47 days, without resolution and lymphocyte recovery, leading to a fatal outcome due to acute respiratory distress syndrome (ARDS) and unspecified sepsis. Conclusion: These two cases highlight the risk for persistent SARS-CoV-2 infection in patients treated with anti-CD20 monoclonal antibodies and support a role for cellular immunity recovery for disease control.
