Abstract

Objective To investigate the clinical features and prognosis of children with fungal bloodstream infection (BSI) following chemotherapy for acute leukemia (AL). Methods A retrospective analysis was performed on 23 children with fungal BSI following chemotherapy for AL in three hospitals in Fujian Province, China, from January 2015 to December 2023. Their clinical features and prognosis were analyzed. Results Among all children following chemotherapy for AL, the incidence rate of fungal BSI was 1.38% (23/1 668). At the time of fungal BSI, 87% (20/23) of the children had neutrophil deficiency for more than one week, and all the children presented with fever, while 22% (5/23) of them experienced septic shock. All 23 children exhibited significant increases in C-reactive protein and procalcitonin levels. A total of 23 fungal isolates were detected in peripheral blood cultures, with Candida tropicalis being the most common isolate (52%, 12/23). Caspofungin or micafungin combined with liposomal amphotericin B had a relatively high response rate (75%, 12/16), and the median duration of antifungal therapy was 3.0 months. The overall mortality rate in the patients with fungal BSI was 35% (8/23), and the attributable death rate was 22% (5/23). Conclusions Fungal BSI following chemotherapy in children with AL often occurs in children with persistent neutrophil deficiency and lacks specific clinical manifestations. The children with fungal BSI following chemotherapy for AL experience a prolonged course of antifungal therapy and have a high mortality rate, with Candida tropicalis being the most common pathogen.
