Clinical characteristics of parainfluenza virus infection in hospitalized children
1Department of Pediatrics, William Beaumont Hospital, Royal Oak, Michigan 48073.
Insights
Children with pre-existing lung conditions like bronchopulmonary dysplasia (BPD) face severe parainfluenza virus (PIV) illness, requiring hospitalization and increased medical support. Protective isolation for BPD patients during PIV outbreaks is recommended to prevent pneumonia.
Area of Science:
- Pediatrics
- Infectious Diseases
- Pulmonology
Background:
- Parainfluenza virus (PIV) infections can cause significant respiratory illness in children.
- Children with underlying pulmonary abnormalities may be at higher risk for severe PIV outcomes.
Purpose of the Study:
- To evaluate the clinical characteristics and severity of PIV infection in hospitalized children.
- To compare outcomes between previously healthy children and those with pre-existing pulmonary abnormalities.
Main Methods:
- Retrospective analysis of 81 hospitalized children over a 4-year period.
- Categorization of patients into previously healthy and those with pre-existing pulmonary abnormalities (BPD, CHD, asthma, prematurity).
- Comparison of illness severity, hospitalization duration, and medical support requirements.
Main Results:
- Children with pre-existing pulmonary abnormalities were more likely to develop lower respiratory tract illness (P < 0.0001).
- These children experienced more severe illness, longer hospital stays, and required more supplemental oxygen (P = 0.047).
- Nosocomial PIV infections, leading to pneumonia, occurred exclusively in patients with bronchopulmonary dysplasia (BPD), who were sicker and required more therapy.
Conclusions:
- Patients with BPD are at high risk for severe PIV-related pneumonia and require intensive medical care.
- Protective isolation for BPD patients during PIV epidemics is crucial to prevent nosocomial infections and reduce disease severity.
Abstract:
Severity of illness and clinical characteristics of parainfluenza virus (PIV) infection were evaluated in 81 hospitalized children over a 4 year period. Fifty three patients were previously healthy and 28 had preexisting pulmonary abnormalities associated with bronchopulmonary dysplasia (BPD), congenital heart disease (CHD), asthma, or prematurity. When compared with formerly healthy children, the patients with preexisting pulmonary abnormalities were more likely to develop lower than upper respiratory tract illness (P less than 0.0001). In the lower respiratory tract infection group, patients with preexisting pulmonary abnormalities were sicker (P = 0.047), were hospitalized longer (P = 0.016), required more supplemental oxygen (P = 0.004), and were older (8.8 vs. 5.1 months) than previously healthy patients. Nosocomial infection occurred only in BPD patients. All these patients developed pneumonia. They were sicker (P = 0.0018), requiring more therapy (P = 0.0038) than other patients with preexisting pulmonary abnormalities and lower respiratory tract disease. Patients with BPD should be placed in protective isolation during PIV epidemics.
