- Abstract
Background: We described the real‐life epidemiology and causes of infections on the different therapy phases in patients undergoing chimeric antigen receptor (CAR) T‐cells directed towards CD19+ or BCMA+ cells. Methods: All consecutive patients receiving CAR T‐cell therapy at our institution were prospectively followed‐up. We performed various comparative analyses of all patients and subgroups with and without infections. Results: Ninety‐one adults mainly received CAR T‐cell therapy for acute leukaemia (53%) and lymphoma (33%). We documented a total of 77 infections in 47 (52%) patients, 37 (48%) during the initial neutropenic phase and 40 (52%) during the non‐neutropenic phase. Infections during the neutropenic phase were mainly due to bacterial (29, 78%): catheter infections (11 [38%] cases), endogenous source (5 [17%]), and Clostridioides difficile (5 [17%]). Patients receiving corticosteroids after CAR T‐cell therapy had a higher risk of endogenous infection (100% vs. 16%; p =.006). During the non‐neutropenic phase, bacterial infections remained very frequent (24, 60%), mainly with catheter source (8, 33%). Respiratory tract infections were common (17, 43%). Conclusions: Infections after CAR T‐cell therapy were frequent. During the neutropenic phase, it is essential to prevent nosocomial infections and balance the use of antibiotics to lower endogenous bacteraemia and Clostridial infection rates.
