BACKGROUND AND PURPOSE: Children with persistent febrile neutropenia (fever > 96 hours) refractory to antibacterial therapy carry a high risk of invasive fungal infection (IFI). However, epidemiologic data in such patient populations is lacking in Taiwan.
METHODS: A retrospective study was conducted to identify risk factors and outcome of IFI in children with persistent febrile neutropenia (> 96 hours) hospitalized at National Taiwan University Hospital from January 1, 1999 through December 31, 1999. They were categorized into proven, probable, possible, or no IFI according to host, microbiologic and clinical criteria.
RESULTS: A total of 29 episodes (35.4%) of IFI occurred in 82 episodes of persistent febrile neutropenia and included 1 proven, 12 probable and 16 possible cases. Pneumonia was most common (69.0%), followed by disseminated infection (17.2%), paranasal sinusitis (6.9%), and hepatosplenic abscess (6.9%). Multivariate analysis revealed 4 risk factors independently associated with IFI: prolonged neutropenia (> 30 days; odds ratio [OR], 10.4; 95% confidence interval [CI], 1.8-60.5), prolonged steroid therapy (OR 2.0, 95% CI 1.0-10.8), allogeneic bone marrow transplantation (OR 5.3, 95% CI 1.0-28.0), and relapsed malignancy (OR 3.5, 95% CI 1.1-11.1). Patients with IFI carried higher in-hospital mortality than those without (51.7% vs 3.8%, p < 0.001). Among those with IFI, delayed antifungal therapy (persistent fever > 7 days) was associated with higher mortality rate than earlier treatment (73.3% vs 28.6%, p = 0.024) and was an independent adverse prognostic factor.
CONCLUSION: IFI was common in patients with persistent febrile neutropenia and delayed antifungal therapy was an independent adverse prognostic factor.
