Popis: Abstract Background Viral reactivations are frequent in hematologial patients due to their cancer‐related and drug‐induced immunosuppressive status. Daratumumab, an anti‐CD38 monoclonal antibody, is used for multiple myeloma (MM) treatment, and causes immunosuppression by targeting CD38‐expressing normal lymphocytes. In this single‐center two‐arm real‐life experience, we evaluated incidence of cytomegalovirus (CMV) reactivation in MM patients treated with daratumumab‐based regimens as first‐ or second‐line therapy. Methods A total of 101 consecutive MM patients were included in this study and were divided into two cohorts: daratumumab and nondaratumumab‐based (control) regimens. Patients treated with >2 lines of therapies were excluded to reduce the confounding factor of multi‐treated cases. Primary endpoint was the CMV reactivation rate. Results CMV reactivation rate was significantly higher in the daratumumab cohort compared to control group (33% vs. 4%; p 1000 UI/mL in 12% of cases; p
