Study Notes
Emphysema
- Emphysema is characterized by permanent enlargement of airspaces distal to terminal bronchioles and destruction of their walls without fibrosis.
- Panacinar emphysema is associated with α1-antitrypsin deficiency.
- Centriacinar emphysema is the most common type in the upper lobes and is associated with smoking.
- Protease-antiprotease imbalance is involved in the pathogenesis of emphysema.
- Neutrophils are the primary source of protease in emphysema.
- Severe emphysema patients often have a barrel-chested appearance.
- Cor pulmonale is a common cause of death in patients with emphysema.
Chronic Bronchitis
- Chronic bronchitis is defined as a persistent productive cough for at least 3 consecutive months in 2 consecutive years.
- About 90% of chronic bronchitis patients are smokers.
- Chronic obstructive bronchitis is characterized by airflow obstruction usually with associated emphysema.
- Mucous glands hypertrophy and hyperplasia are hallmarks of chronic bronchitis.
- Weight loss is not typically associated with chronic bronchitis.
- Patients with severe chronic bronchitis are often referred to as "blue bloaters".
Bronchial Asthma
- Extrinsic asthma is mediated by IgE and TH2 responses.
- Intrinsic asthma is triggered by viral infections, exercise, and other factors.
- Mast cells and eosinophils are involved in the airway inflammation of asthma.
- Airway inflammation, intermittent airway obstruction, and bronchial hyper-responsiveness are components of asthma's pathophysiology.
- Chest tightness is a main feature of an acute asthma attack.
- Status asthmaticus is a severe asthma attack that does not respond to therapy.
- Bronchial wall thickening is a characteristic of airway remodeling in asthma.
- Aspirin is a major mediator in non-atopic asthma.
Bronchiectasis
- Bronchiectasis is characterized by permanent dilation of bronchi and bronchioles.
- Tumors, foreign bodies, and cystic fibrosis are causes of bronchiectasis.
- Staphylococcus aureus and Klebsiella spp. are microorganisms commonly associated with necrotizing pneumonia leading to bronchiectasis.
- Productive cough with mucopurulent sputum is a common clinical feature of bronchiectasis.
- Clubbing of the fingers and pulmonary hypertension are complications of bronchiectasis.
- Chronic persistent infection and bronchial obstruction are primary pathogeneses of bronchiectasis.
General Knowledge on Obstructive Lung Diseases
- Emphysema, chronic bronchitis, and asthma are considered obstructive lung diseases.
- Pulmonary fibrosis is not considered an obstructive lung disease.
- Increased resistance to airflow is a common feature of obstructive lung diseases.
- Pulmonary function test (PFT) is crucial for diagnosing obstructive lung diseases.
- In obstructive lung diseases, the FEV1/FVC ratio is typically reduced.
- Airway hyperresponsiveness is a hallmark of chronic obstructive bronchitis.
- Chronic airflow obstruction with emphysema is a characteristic of chronic obstructive bronchitis.
