Safety of empirical antibiotic therapy discontinuing for fever of unknown origin during high-risk neutropenia in children - 17/05/24
Summary |
Background |
ECIL-2021 recommends discontinuing empirical antibiotic therapy (EAT) in febrile-neutropenic children after 72 h of treatment and at least 24–48 h of apyrexia in the case of fever of unknown origin (FUO). These guidelines are rarely applied to high-risk children's neutropenia.
Material and methods |
We retrospectively included all consecutive FUO episodes occurring during profound neutropenia ≥ 10 days in children in our institution. We evaluated the safety of EAT discontinuation in patients for whom the ECIL guidelines were followed compared to those for whom they didn’t. We used a combined criterion of mortality and intensive care unit admission at 30 days. We identified risk factors for recurrent fever after EAT discontinuation.
Results |
Fifty-one FUO episodes occurred in 37 patients. EAT discontinuation followed ECIL guidelines in 19 (37 %) episodes. No deaths and-or transfers in ICU occurred in the ECIL group. The duration of EAT was shorter by nine days in the group following ECIL guidelines (p < 0.001). We observed 14 (27 %) episodes of recurrent fever. Mucositis was significantly associated with recurrent fever (p < 0.01).
Conclusion |
EAT discontinuation seems feasible and safe in FUO during prolonged febrile neutropenia in children. However, mucosal lesions should prompt thorough surveillance due to the risk of recurrent fever.

• | Discontinuation of antibiotics is uncommon in high-risk neutropenia. |
• | Studies on antibiotic therapy discontinuation in neutropenia are very heterogeneous. |
• | Antibiotic discontinuation could be safely performed in febrile neutropenia. |
• | Discontinuation of antibiotics should be careful in the presence of mucosal lesions. |
