Invasive fungal infections in immunocompromised children in paediatric haematology: Recommendations for management in SFCE centres

Introduction > To date, invasive fungal infections (IFIs) are still responsible for a high mortality rate in children managed for haematological malignancy. Although Candida and Aspergillus infections remain in the majority, emerging fungal infections are increasingly common. Children differ from adults in their pathology and treatment, as well as in their prior fungal colonisation and unique pharmacokinetics. Therefore, we propose here specific paediatric management recommenda-tions for IFIs in haematology.Methods > We based our recommendations on a review of the literature, including the latest ECIL recommendations, an analysis of practices and a collection of expert opinions.Results and discussion > In France, approximately 5% of children treated for haematological malignancy or who have received a bone marrow allograft present an IFI. These IFIs are equally divided between yeast infections (mainly due to Candida albicans) and filamentous infections (mainly aspergillosis) and 16% are IFIs due to emerging fungi, half of which are due to Mucorales. In these recommendations, we recall the diagnostic criteria for proven or probable IFI according to the Donnelly classification, then we propose strategies for screening, diagnosing, evaluating the extension and treating these three types of IFI. We also detail the diagnostic and therapeutic management of chronic disseminated candidiasis. We also discuss prophylactic measures, including environmental measures which are of primary importance in children.
