Insights
Febrile children with severe neutropenia (low neutrophil count) have a low risk of severe bacterial infection. Outcomes are similar to those with moderate neutropenia, suggesting watchful waiting may be appropriate.
Area of Science:
- Pediatric Emergency Medicine
- Hematology
Background:
- Fever and neutropenia in children can cause clinical concern.
- Evaluation is often extensive, even in immunocompetent children.
Purpose of the Study:
- To determine outcomes for previously healthy, febrile children presenting with severe neutropenia.
Main Methods:
- Retrospective review of infants and children (3-36 months) with fever and severe neutropenia (neutrophil count <500 × 10^3/μL).
- Comparison with a similar cohort experiencing moderate neutropenia (500-1000 × 10^3/μL).
Main Results:
- Severe bacterial infection (SBI) occurred in 1.9% of 52 patients with severe neutropenia.
- No significant difference in SBI incidence was observed compared to patients with moderate neutropenia.
Conclusions:
- Immunocompetent children with fever and severe neutropenia do not have an increased risk of SBI compared to those with moderate neutropenia.
- Close monitoring of blood counts for bone marrow recovery may be a viable alternative to antibiotics.
Background:
Neutropenia may alarm clinicians and prompt extensive evaluation in children with fever, even in immunocompetent patients.
Objective:
Our aim was to determine outcomes in previously healthy febrile children presenting to the emergency department with severe neutropenia.
Methods:
We reviewed data from infants and children aged 3-36 months with fever and severe neutropenia, defined as a peripheral neutrophil count <500 × 103/μL, at our institution between January 1, 2012 and December 31, 2015. We compared our results to those from a similar study of children with a peripheral neutrophil count of 500-1000 × 103/μL.
Results:
Severe neutropenia was recorded in 52 patients; severe bacterial infection (SBI) was found in 1 (1.9%), but none had a positive blood culture. Incidence of SBI was not different from that found in a study of similar patients with moderate neutropenia.
Conclusions:
Immunocompetent patients with fever and severe neutropenia do not carry a higher risk for SBI compared to patients with fever and moderate neutropenia. Such patients could potentially be followed closely with serial blood counts to ensure bone marrow recovery, without the use of antibiotics.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
