Insights
Recurrent pneumonia in children often has underlying causes like aspiration and primary immunodeficiency. Identifying these causes and risk factors is crucial for managing severe outcomes and rehospitalization.
Area of Science:
- Pediatric Pulmonology
- Clinical Medicine
- Genetics
Background:
- Recurrent pneumonia (RP) in hospitalized children presents a significant clinical challenge.
- Understanding the underlying causes and risk factors for adverse outcomes is essential for effective management.
Approach:
- A retrospective review of medical records for hospitalized children diagnosed with RP was conducted.
- Logistic regression analysis was used to identify associations between various factors and adverse outcomes.
Key Points:
- The majority of children (87.7%) with RP had identifiable underlying causes, most commonly recurrent aspiration, primary immunodeficiency (PID), and congenital heart diseases.
- Genetic defects were identified in 28.7% of patients.
- Risk factors for severe outcomes included PID, primary ciliary dyskinesia, bronchiolitis obliterans, and RP diagnosis after age 3.
- Aspiration and abnormal family history were risk factors for rehospitalization.
Conclusions:
- Underlying causes are prevalent in hospitalized children with recurrent pneumonia.
- Genetic factors play a notable role in the etiology of RP.
- Identifying specific risk factors aids in predicting and mitigating severe outcomes and rehospitalization.
Objectives:
To describe the clinical characteristics and underlying causes of recurrent pneumonia (RP) among hospitalized children, and to identify risk factors associated with adverse outcomes.
Methods:
We reviewed the medical records of hospitalized children diagnosed with RP at the Children's Hospital of Fudan University from January 2016 to January 2021 and then described clinical characteristics and underlying causes. The associations between factors and adverse outcomes were assessed using logistic regression.
Results:
Of 551 children with RP, 483 (87.7%) manifested underlying causes, with recurrent aspiration (127, 23.0%), primary immunodeficiency (PID) (91, 16.5%), and congenital heart diseases (63, 11.4%) being the most common. Genetic defects were identified in about a quarter (158, 28.7%) of the patients. PID odds ratio (OR, 7.9; 95% confidence interval [CI], 2.8-22.8), primary ciliary dyskinesia (OR, 12.9; 95% CI, 3.0-54.8), bronchiolitis obliterans (OR, 7.0; 95% CI, 1.7-28.5), and a diagnosis of RP at an age of >3 years (OR, 3.4; 95% CI, 1.3-9.0) were risk factors for severe outcomes. Aspiration (OR, 2.9; 95% CI, 1.3-6.3) and an abnormal family history (OR, 3.3; 95% CI, 1.3-8.2) were risk factors for rehospitalization.
Conclusions:
The majority (87.7%) of hospitalized children with RP exhibited underlying causes, and genetic defects were common.
