In conclusion, clinical and biochemical data of COVID-19 might be partly masked by coexisting chronic lymphocytic leukaemia; better diagnostic strategies (ie, superior CT differential techniques such as radiomics) could be used for diagnosis; individuals with compromised immune status might be subjected to a longer incubation period (although the underlying mechanisms are not known); and it remains uncertain whether the combination of chemotherapy, corticosteroids, α-interferon, and immunoglobulins could work synergistically in patients with chronic lymphocytic leukaemia and COVID-19.
