Febrile neutropenia is a common infectious complication in children and adolescents receiving chemotherapy for cancer, requiring immediate hospitalisation and empirical antibacterial therapy. The risk for a severe infection increases with lower neutrophil counts, but other factors such as underlying malignancy, remission state or the genetic background might also impact on the risk and severity of infection. Initial antibacterial treatment as well as modification and cessation of therapy depends on clinical performance, microbiological findings and haematological recovery. Although paediatric specific guidelines have been developed in the last decade, a number of questions are still unsolved. This article gives an overview on diagnostics and management of paediatric patients presenting with febrile neutropenia, on research gaps and will speculate on future perspective.
Invasive aspergillosis (IA) is a major cause of morbidity and mortality in children with hematological malignancies and those undergoing hematopoietic stem cell transplantation. Similar to immunocompromised adults, clinical signs, and symptoms of IA are unspecific in the pediatric patient population. As early diagnosis and prompt treatment of IA is associated with better outcome, imaging and non-invasive antigen-based such as galactomannan or Ăź-D-glucan and molecular biomarkers in peripheral blood may facilitate institution and choice of antifungal compounds and guide duration of therapy. In patients in whom imaging studies suggest IA or another mold infection, invasive diagnostics such as bronchoalveolar lavage and/or bioptic procedures should be considered. Here we review the current data of diagnostic approaches for IA in the pediatric setting and highlight the major differences of performance and clinical utility of the tests between children and adults.
