Abstract
Patients with multiple myeloma (MM) are at an increased risk for infection because of their immunocompromised state, old age, and comorbidities. 1 Coronavirus disease 2019 (COVID-19) causes moderate to severe acute respiratory dysfunction in 77% of patients with MM, and ~8% end up in critical condition. 2 More than 80% of patients with MM who are infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) require hospitalization, 3 whereas ~33% of hospitalized MM patients with COVID-19 may die because of the infection. 4 This is mainly due to the limited therapeutic options for COVID-19.
