Sumario:BACKGROUND: Combination antifungal therapy (CAF) is often prescribed to treat invasive fungal infections, despite equivocal data showing benefit. We evaluated number of CAF for treatment of proven, probable and possible invasive fungal infection (IFI) in hospitalized children, associated adverse effects (AE), and use of therapeutic drug monitoring (TDM). METHODS: Medical charts of patients ≤ 18 years old that received CAF for ≥72 hours with normal liver function test between 1/1/13 through December 31/18 were reviewed. Patients could be included for multiple episodes of CAF. Data included primary site of IFI, host risk factors, demonstration of fungal elements in tissue/sterile sites, clinical and mycological criteria for IFI (defined by European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and National Institute of Allergy and Infectious Diseases Mycoses Study Group), CAF regimen, incidence of TDM, and AE. RESULTS: Overall, 73 episodes of IFI were reviewed [unique patients (n) =60]. The median age was 10 years. Majority (61.6%) of patients were diagnosed with a hematological malignancy (n = 20 acute lymphoblastic leukemia, n = 12 acute myeloid leukemia, n = 5 aplastic anemia). A number of proven, possible, probable IFI were 36, 27 and 20, respectively (Table 1). Most frequent organism isolated in proven IFI was Aspergillus fumigatus (episodes=5, n = 4). Most common primary site of IFI was pulmonary (episodes=32, n = 27). Median days of CAF was 6.8 (range: 3–170). Sixty-six episodes included treatment with a triazole-containing regimen (90%). TDM was conducted in 51 (77%) episodes of triazole-containing regimens. AE were reported in 14 episodes (n = 10) (infusion-related reactions and nephrotoxicity reported in 4 episodes each, electrolyte abnormalities and skin reaction reported in 2 episodes each, and liver dysfunction and hypersensitivity reported in 1 episode each). CONCLUSION: Patients diagnosed with proven or probable IFI received a longer duration of CAF in comparison to possible IFI. Voriconazole was frequently prescribed in combination with either micafungin or liposomal amphotericin B for IFI. Antifungal stewardship opportunities exist to improve TDM and reduce the incidence of AE when prescribing CAF. [Image: see text] DISCLOSURES: All authors: No reported disclosures
