Insights
Bronchiolitis Obliterans (BO) is a rare obstructive lung disease. This review focuses on the post-infectious type in children, its epidemiology, diagnosis, and treatment.
Area of Science:
- Pulmonology
- Pediatric Respiratory Medicine
Background:
- Bronchiolitis Obliterans (BO) is a rare, chronic obstructive lung disease affecting the small airways.
- In children, it commonly presents as post-infectious BO following severe viral infections.
- Post-transplant BO is increasing due to organ and bone-marrow transplants.
Purpose of the Study:
- To review current evidence on post-infectious Bronchiolitis Obliterans in children.
- To discuss epidemiology, diagnosis, treatment, and prognosis.
- To highlight areas of controversy for future research.
Main Methods:
- Literature review of up-to-date evidence.
- Synthesis of information on epidemiology, diagnosis, treatment, and prognosis.
- Identification of controversial aspects and future research directions.
Main Results:
- Post-infectious BO in children is linked to early-life viral infections.
- Post-transplant BO is progressive, unlike the generally non-progressive post-infectious form.
- Both forms share pathological pathways leading to bronchiolar obliteration.
Conclusions:
- Post-infectious Bronchiolitis Obliterans requires further investigation regarding its long-term course and management.
- Understanding shared pathways may offer therapeutic insights.
- Further research is needed to address current controversies and improve patient outcomes.
Abstract:
Bronchiolitis Obliterans (BO) is an infrequent chronic and obstructive lung disease secondary to an insult to the terminal airway and its surroundings. In children, the most common presentation is the post-infectious variant, closely related to a severe viral infection in the first three years of life. However, the increase in the number of lung and bone-marrow transplants has also been followed by an increase in post-transplant BO. Post-transplant BO is progressive while post-infectious BO does not seem to be, but both forms share some common pathways that result in a characteristic histopathology of bronchiolar obliteration. This review covers up-to-date evidence on epidemiology, diagnosis, treatment and prognosis of post-infectious bronchiolitis obliterans, including areas of controversy that need to be addressed in future studies.

Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
