Pulmonary involvement with cytomegalovirus infections in children
Insights
Cytomegalovirus (CMV) infection in hospitalized children frequently causes respiratory issues like interstitial pneumonitis. Underlying conditions significantly impact the severity and outcome of CMV-related lung disease.
Area of Science:
- Pediatric Infectious Diseases
- Pulmonology
- Virology
Background:
- Cytomegalovirus (CMV) is a common viral infection that can cause significant morbidity in hospitalized infants and children.
- Pulmonary involvement is a recognized complication of CMV infection, particularly in immunocompromised individuals.
Purpose of the Study:
- To describe the spectrum of pulmonary manifestations of cytomegalovirus infection in hospitalized pediatric patients.
- To identify factors associated with the severity and mortality of CMV-induced lung disease in children.
Main Methods:
- Retrospective analysis of 40 hospitalized infants and children diagnosed with cytomegalovirus infection.
- Clinical data, including respiratory symptoms, radiographic findings, and outcomes, were reviewed.
Main Results:
- Interstitial pneumonitis was observed in 35% of patients.
- Wheezing or tachypnea without classical interstitial pneumonia occurred in 10% of cases.
- Pulmonary involvement was more severe and prolonged in children with pre-existing lung conditions or immunodeficiency.
- Mortality and disease severity were linked to underlying immunodeficiency or concurrent pulmonary processes.
Conclusions:
- Cytomegalovirus infection presents with diverse pulmonary manifestations in children, ranging from interstitial pneumonitis to less defined respiratory symptoms.
- The presence of underlying pulmonary pathology or immunodeficiency significantly worsens the prognosis of CMV-related lung disease.
- Early recognition and management of CMV pulmonary disease are crucial, especially in vulnerable pediatric populations.
Abstract:
Among 40 hospitalized infants and children with cytomegalovirus infection, 14 (35%) had interstitial pneumonitis, 4 (10%) had wheezing or tachypnoea but without x-ray evidence of classical interstitial pneumonia, the remaining 22 (55%) were free of pulmonary involvement. Most patients had tachypnoea and nonproductive cough of varying durations: those with underlying pulmonary pathology tended to have persistent and prolonged respiratory symptoms. Mortality and severity of the lung disease were related to the underlying immunodeficiency or concomitant pulmonary process.
