BACKGROUND Invasive fungal infections are responsible for significant morbidity and mortality. Safety and effectiveness of antifungal agents is a particular concern in pediatric populations, where data are often limited. Micafungin is an echinocandin with demonstrated antifungal activity against a wide spectrum of Candida spp.; this subanalysis of data from the MYRIADE study describes the use of micafungin and its therapeutic outcomes in pediatric patients, in normal clinical practice. METHODS MYRIADE was an observational, multicenter, national, prospective, longitudinal study conducted from January 2010 to December 2012, in patients treated with micafungin using a prophylactic or curative strategy, across 17 sites [oncohematology (n = 8), neonatal intensive care units (ICUs) (n = 5) and pediatric ICUs (n = 4)]. The treatment regimen, the achievement of the therapeutic objective and the tolerance were reported. RESULTS The study population consisted of 110 pediatric patients (31 neonates, 24 children <2 years old and 55 children ≥2 to <16 years old). The therapeutic objective was achieved in 49/64 (76.6%) oncohematology patients, 28/29 (96.6%) neonatal ICU patients and 12/14 (85.7%) pediatric ICU patients. Twenty-four (21.8%) children developed an adverse event (AE); more AEs were observed in oncohematology patients compared with ICU patients [17 (26.1%) vs. 7 (15.6%)]. Only one serious AE, reported in an oncohematology patient, was considered related to micafungin. CONCLUSIONS In the first large observational study of micafungin treatment or prophylaxis conducted under real-world conditions in France, micafungin was effective and well tolerated for prophylaxis of invasive fungal infections in pediatric oncohematology patients and for curative purposes in pediatric and neonatal ICU patients.
