Giant cell pneumonia associated with parainfluenza virus type 3 infection
Human Pathology
|May 1, 1981
Abstract:
Giant cell pneumonia associated with parainfluenza virus type 3 infection and chronic poliovirus type 2 meningoencephalomyelitis are documented in an infant with combined immunologic deficiency (Swiss type). Caution should be exercised in attributing cases of giant cell pneumonia to measles virus without serologic or virologic evidence.
Insights
Giant cell pneumonia in an infant was linked to parainfluenza virus type 3. Researchers caution against attributing such pneumonia to measles without definitive evidence.
Area of Science:
- Immunology
- Virology
- Pediatric Medicine
Background:
- Combined immunologic deficiency (Swiss type) presents significant challenges in managing infections.
- Viral infections can manifest with severe respiratory and neurological complications in immunocompromised infants.
Observation:
- An infant diagnosed with combined immunologic deficiency experienced severe illness.
- The infant presented with giant cell pneumonia and meningoencephalomyelitis.
Findings:
- Parainfluenza virus type 3 was identified as the causative agent for giant cell pneumonia.
- Chronic poliovirus type 2 meningoencephalomyelitis was also documented in the same patient.
- The study highlights the importance of accurate viral diagnostics.
Implications:
- Accurate identification of viral pathogens is crucial for appropriate treatment in immunocompromised infants.
- Clinical presentation of giant cell pneumonia necessitates careful exclusion of various viral etiologies.
- This case underscores the need for robust virologic and serologic testing to confirm measles virus involvement.
