What characterizes bronchiectasis in terms of airway condition?

Bronchiectasis is characterized by abnormal irreversible enlargement of the airways.

How is bronchiectasis categorized in terms of its impact on airway function?

Bronchiectasis is categorized as a chronic obstructive suppurative airway disease.

What is the primary pathological change that leads to bronchiectasis?

The primary pathological change is the destruction of airway architecture.

Why is bronchiectasis considered irreversible?

Bronchiectasis is considered irreversible due to the permanent enlargement of the airways. Signup and view all the answers

What does the term 'idiopathic' mean in the context of connective tissue disease cases?

'Idiopathic' refers to cases where the cause of the disease is unknown despite thorough medical evaluation. Signup and view all the answers

Why might advanced evaluations still result in an idiopathic label for many connective tissue disease cases?

Advanced evaluations may fail to identify a specific cause due to the complexity and variability of these diseases. Signup and view all the answers

How might connective tissue diseases affect immune function beyond immunoglobulin levels?

It implies that treating the underlying cause may not improve current symptoms. Signup and view all the answers

What is the primary goal of treating the underlying cause of irreversible airway dilation?

The primary goal is to prevent further progression of the condition. Signup and view all the answers

Why might current symptoms not improve even after treating the underlying cause?

Study Notes

Bronchiectasis

Bronchiectasis is a chronic, obstructive, suppurative airway disease
Characterized by abnormal and irreversible enlargement of the airways
Airways are damaged due to destruction of the airway architecture
Bronchi and bronchioles normally narrow as they go deeper
In bronchiectasis, they maintain the same caliber or dilate as they go distally.

Objectives

Define bronchiectasis
Detail causes of bronchiectasis
Identify clinical features of bronchiectasis
Diagnose bronchiectasis
Treat bronchiectasis

Causes

Infection-Related:
- Tuberculosis (most common)
- Nontuberculous mycobacteria
- Pneumonia (especially recurrent)
- Whooping cough
- Measles
Airway Obstruction:
- Tumor
- Enlarged hilar lymph nodes
- Foreign body
Immunodeficiency:
- Common variable immunodeficiency
- Primary hypogammaglobulinaemia
- HIV
Hypersensitivity:
- Allergic bronchopulmonary aspergillosis
Autoimmune Disorders:
- Rheumatoid arthritis
- Sjogren's syndrome
- Inflammatory bowel disease
Mucociliary Dysfunction:
- Cystic fibrosis
- Primary ciliary dyskinesia
- Kartagener syndrome
- Primary hypogammaglobulinaemia

Clinical Picture

Symptoms:
- Chronic, daily, persistent cough
- Copious (over 100 ml/day) and continuously purulent sputum
- Pleuritic pain (when infection involves the pleura or with segmental collapse due to retained secretions)
- Dyspnea
Other Symptoms:
- Haemoptysis (streaks or larger volumes, sometimes requiring bronchial artery embolisation)
- Infective exacerbation (increased sputum, fever, malaise, anorexia)
- Halitosis (bad breath, commonly with purulent sputum)
- General debility (difficulty maintaining weight, anorexia, exertional breathlessness)

Signs

Clubbing of fingers
Coarse inspiratory and expiratory crepitation (changes after coughing, caused by air passing through mucus-filled bronchi)
Wheezing (in advanced cases, caused by scarring and overlying bronchial breathing)

Investigations

CXR: May show mild bronchiectasis (not always apparent), ring shadows/tramlines (thick airways), or honey-comb appearance (late).
Bronchoscopy: Detect site of haemoptysis and underlying cause
PFT (pulmonary function test): Obstructive pattern with incomplete reversibility (similar to COPD)
High-resolution chest CT scan: Used to diagnose bronchiectasis.
- Diagnostic criteria include airway diameter greater than accompanying vessel, lack of distal airway tapering, and presence of bronchial wall thickening or cysts
Sputum culture: Reveals organisms such as Pseudomonas aeruginosa, Staphylococcus aureus, fungi (aspergillus), and non-tuberculous mycobacteria
Sputum microbiology: Including atypical organisms (acid-fast bacilli and Aspergillus)
Immunoglobulin levels: Checked if ciliary dysfunction is suspected
Nasal FeNO sampling: Screening test for ciliary dysfunction, followed by nasal brush biopsy (if FeNO abnormal) and genetic testing
Connective tissue disease and immune function evaluation: Including immunoglobulin levels
Even with advanced evaluation, more than half of bronchiectasis cases are idiopathic (unknown cause).

Treatment

Treatment focuses on clearing the airway, treating infections, and preventing exacerbations
Physiotherapy (postural drainage): 5-10 minutes, once or twice daily, to empty secretions
Bronchodilators: For obstruction
Antibiotics: For infections (Haemophilus influenzae, Pseudomonas aeruginosa, Klebsiella spp., Streptococcus pneumoniae are common)
Mucolytics: For thick sputum
Surgery: Considered if unilateral and confined to a lobe.
Vaccines: Influenza and pneumococcal vaccines; smoking cessation advised
Treatment of underlying cause: May not improve current symptoms, but might prevent future progression

Complications

Respiratory failure
Recurrent infection
Pulmonary hypertension (cor pulmonale)
Pneumothorax
Brain abscess
Amyloidosis (AA type, resulting in nephrotic syndrome)
