Pediatric Invasive Aspergillosis: A Retrospective Review of 59 Cases

Abstract

Invasive aspergillosis (IA) is an important cause of morbidity and mortality. In this study, we aimed to present our 10-year IA experience in a single center. Fifty-nine pediatric patients diagnosed with IA were included in the study. The male/female ratio of these patients was 42/17. The median age was 8.75 years. Hematologic malignancy was present in the majority of the patients (40/59, 68%). The mean duration of neutropenia was 18.5 days. Cytosine arabinoside was the most common immunosuppressive therapy directed at T-cells at the time of IA diagnosis. IA cases were categorized as proven (27%), probable (51%) and possible (22%) according to the 2008 EORTC/MSG criteria. The most common site of invasive aspergillosis was the lungs (78%) and nodules were the most frequent radiological finding (75.5%). In 38 (64.4%) patients receiving antifungal prophylaxis, prophylactic agents included fluconazole (30.5%), liposomal amphotericin B (23.7%), posaconazole (8.5%) and voriconazole (1.7%) Initial treatment was most commonly administered as monotherapy (69.5%). The median duration of antifungal treatment was 67 days. A total of 11 (18.6%) deaths occurred due to aspergillosis. We will probably continue to see IA frequently in pediatric patients with increased use of corticosteroids, biological agents, and intensive immunosuppressive chemotherapies.
