[Respiratory sequelae of severe measles (author's transl)]
Insights
Severe measles pneumonia in young children can lead to chronic airflow obstruction. This condition, characterized by persistent respiratory issues, requires long-term monitoring and has a guarded prognosis.
Area of Science:
- Pediatric Pulmonology
- Infectious Diseases
- Respiratory Medicine
Context:
- Measles infection in young children can cause severe bronchopneumonia.
- Respiratory sequelae following viral infections are a significant concern in pediatric health.
Purpose:
- To investigate the long-term respiratory consequences of severe measles bronchopneumonia in children.
- To describe the clinical, radiological, and pathological features of measles-induced chronic airflow obstruction.
Summary:
- Six children aged 13 months to 4 years developed chronic airflow obstruction after severe measles bronchopneumonia.
- Findings included bronchiolar obstruction, bronchiectasis, airway distension, and thickened peribronchial walls.
- Symptoms like breathlessness, wheezing, and cyanosis were poorly responsive to standard treatments.
Impact:
- Identifies measles as a potential cause of permanent respiratory damage in children.
- Highlights the need for prolonged follow-up and guarded prognosis for affected children.
- Suggests associated viral infections, like adenovirus, may contribute to these sequelae.
Abstract:
Six healthy children, 5 boys and 1 girl aged from 13 months to 4 years had a severe measles bronchopneumonia. The end result is established chronic airflow obstruction. On a background of fairly severe respiratory failure there were paroxysms of breathlessness with fever, wheezes and cyanosis which were little affected by bronchodilators or steroids. The anatomical basis of this syndrome is before all else a bronchiolar obstruction, shown at autopsy in a child dying after four months of the illness. But also there is a disorder of the large bronchi with bronchiectasis and problems with ventilation centrally and/or peripherally. The major radiological signs are airways distension which is always clearly in keeping with emphysema and a thickening of the peri-bronchial walls which are clearly visible on tomography. Thus it appears that measles, as with other respiratory viruses, can lead to permanent sequelae in very young children. It is however possible that the respiratory sequelae may be due to associated viral infections, with adenovirus in particular. On the practical level, the occurrence of an early and severe measles pneumonia in a young child and its persistence with a hypoxia and a lowering of dynamic compliance requires a prolonged follow up and a guarded prognosis. Unfortunately the treatment of this type of chronic airflow obstruction is only symptomatic.
