Background:
Invasive fungal infection (IFI) is a critical complication in the management of hematologic and malignant disease. Given that there is a tendency for IFI to occur after bacteremia following febrile episodes during neutropenia, the aim of this study was to determine if bacteremia was a predictive factor for IFI in pediatric patients with hematologic and malignant disease.
Methods:
Sixty-two patients (32 boys, 30 girls; median age, 4 years) with hematologic or malignant disease who had received chemotherapy, immunosuppressive therapy, and/or hematopoietic stem cell transplantation, and experienced febrile episodes during neutropenia were enrolled. In patient-based analysis, clinical features of 62 patients were compared between those with and without IFI. Meanwhile, in febrile episode-based analysis, clinical features were analyzed for 268 febrile episodes occurring during neutropenia in the 62 patients.
Results:
Patient-based analysis showed that relapse of original disease and acute myeloid leukemia were risk factors for IFI. Meanwhile, febrile episode-based analysis identified bacteremia following febrile episodes during neutropenia as a potential risk factor for IFI.
Conclusions:
This is the first report to identify bacteremia following febrile episodes during neutropenia as a predictive factor for IFI in pediatric patients with hematologic or malignant disease. When bacteremia is detected in such patients, sufficient preventive measures against IFI, including intensive use of antifungal agents, are warranted.
Insights
Bacteremia following febrile episodes during neutropenia is a predictive factor for invasive fungal infection (IFI) in pediatric patients with hematologic or malignant disease. Early detection and antifungal measures are crucial for preventing IFI.
Area of Science:
- Pediatric Hematology-Oncology
- Infectious Diseases
- Critical Care Medicine
Background:
- Invasive fungal infection (IFI) is a serious complication in pediatric patients with hematologic and malignant diseases.
- IFI often follows bacteremia during neutropenic febrile episodes.
- Predictive factors for IFI in this vulnerable population require further investigation.
Purpose of the Study:
- To determine if bacteremia is a predictive factor for invasive fungal infection (IFI).
- To investigate the relationship between bacteremia and IFI in pediatric patients undergoing chemotherapy or stem cell transplantation.
- To identify risk factors for IFI in pediatric hematology-oncology patients.
Main Methods:
- A study involving 62 pediatric patients with hematologic or malignant disease experiencing febrile episodes during neutropenia.
- Patient-based analysis comparing clinical features of those with and without IFI.
- Febrile episode-based analysis of 268 episodes to identify risk factors for IFI.
Main Results:
- Patient-based analysis identified disease relapse and acute myeloid leukemia as risk factors for IFI.
- Febrile episode-based analysis revealed bacteremia following febrile episodes during neutropenia as a potential risk factor for IFI.
- This study highlights bacteremia as a key indicator for IFI risk.
Conclusions:
- Bacteremia following febrile episodes during neutropenia is identified as a predictive factor for IFI in pediatric hematology-oncology patients.
- Early detection of bacteremia warrants prompt preventive measures against IFI.
- Intensive use of antifungal agents is recommended when bacteremia is detected in these patients.
