Cefiderocol in Children with Hematologic Malignancies-The Multicenter Retrospective Experience of the Infection Working Group of the Italian Pediatric Hematology and Oncology Association (AIEOP)
Abstract
Background/Objectives: Immunocompromised children undergoing chemotherapy or allogeneic hematopoietic stem cell transplantation (HSCT) for hematologic disorders face a high risk of serious, life-threatening infections caused by multidrug-resistant (MDR) bacteria. Cefiderocol is a novel siderophore cephalosporin, indicated for use in adult patients with MDR Gram-negative infections. Clinical data in immunocompromised children are limited. To report a multicenter real-life experience from the Infection Working Group of the Italian Pediatric Hematology and Oncology Association (IWG-AIEOP) on the use of cefiderocol in treating pediatric onco-hematologic patients with severe, high-risk infections. Methods: Multicenter retrospective collection of infectious episodes treated with cefiderocol, from January 2021 to December 2024, in patients 18 years or younger, after treatment for malignancies or undergoing HSCT in the AIEOP network, part of a prospective, observational study on the etiology and outcome of febrile episodes among 24 AIEOP centers (code NCT06419426). Results: Fifteen episodes of MDR, life-threatening Gram-negative infections treated with cefiderocol in 13 pediatric onco-hematologic patients were collected. There were eight males and five females, mainly affected by acute leukemia (six lymphoblastic and four myeloid, three other hematologic malignancies). The median age was 11.1 years (range 1-17.4 years), and the median weight was 37.8 kg (range 8-65). Bloodstream…
