Bronchiolitis, an inflammation of small airways, is linked to systemic diseases like Sjögren's syndrome and rheumatoid arthritis. Early diagnosis and treatment are crucial for managing this condition and preventing respiratory insufficiency.
Area of Science:
- Pulmonary Medicine
- Rheumatology
- Immunology
Context:
- Bronchiolitis, or small airway inflammation, is frequently associated with systemic autoimmune diseases.
- Key conditions include Sjögren's syndrome, rheumatoid arthritis, and chronic inflammatory bowel disease.
- Cellular infiltration and lymphoid follicles characterize some cases, while others show constrictive fibrosis.
Purpose:
- To highlight the connection between distal airway inflammation and systemic diseases.
- To emphasize diagnostic clues for bronchiolitis in patients with atypical respiratory symptoms.
- To discuss treatment challenges and prognostic factors.
Summary:
- Bronchiolitis presents with varied histopathology, including lympho-monocytic infiltration or peribronchiolar fibrosis.
- Diagnosis requires suspicion in atypical asthma/bronchitis, alongside extrarespiratory signs and autoantibody testing.
- Imaging (CT) and pulmonary function tests aid diagnosis, with limited treatment efficacy and potential need for lung transplantation.
Impact:
- Improved recognition of bronchiolitis in systemic disease contexts.
- Enhanced diagnostic strategies for challenging respiratory conditions.
- Informed therapeutic decisions and consideration of advanced interventions like lung transplantation.

Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
Primary Symptoms of COPD:
Chronic Obstructive Pulmonary Disease II: Emphysema
The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
COPD: Pathogenesis and Clinical Features
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
