Study Notes
Chronic Obstructive Pulmonary Disease (COPD)
- COPD leads to progressive airflow limitation, primarily due to chronic inflammation from harmful substances, especially cigarette smoke.
- Affects individuals typically over the age of 40, with increasing prevalence in smokers and is the third leading cause of death globally.
- The 2015 data indicated approximately 174 million cases and about 3.2 million deaths due to COPD worldwide.
- Significant underdiagnosis may inflate actual prevalence rates.
Etiology and Pathophysiology
- Common causes include cigarette smoke, second-hand smoke, and environmental or occupational exposures.
- Alpha-1 Antitrypsin Deficiency (AATD) is a rare genetic factor leading to emphysema through protease-mediated damage.
- COPD involves oxidative stress, airway inflammation, and protease-antiprotease imbalance, resulting in structural lung changes, such as emphysema.
Clinical Presentation
- Typical symptoms include chronic dyspnea, cough, sputum production, wheezing, and chest tightness.
- Acute exacerbations can be triggered by infections (bacterial or viral), environmental irritants, and increased inflammation.
- Patients often exhibit signs of respiratory distress, use accessory muscles for breathing, and may present with barrel chest or cyanosis in severe cases.
Evaluation and Diagnosis
- Diagnosis relies on spirometry, with a FEV1/FVC ratio < 0.7 confirming COPD.
- Additional tests include the 6-minute walk test, laboratory work for infection and AATD, and imaging like chest X-rays and CT scans.
- GOLD guidelines provide a framework for assessing disease severity and treatment options.
Management Strategies
- Treatment goals: symptom control, quality of life improvement, and reduction in exacerbations.
- Non-pharmacological: Smoking cessation, pulmonary rehabilitation, and vaccinations (influenza and pneumococcal).
- Pharmacological options include bronchodilators (SABAs and LABAs), inhaled corticosteroids (ICS), systemic glucocorticoids, and PDE4 inhibitors like Roflumilast.
Acute Exacerbation Management
- Mild exacerbations: treated outpatient with bronchodilators, corticosteroids, and antibiotics as needed.
- Moderate/severe exacerbations require inpatient care, often involving oxygen therapy and possibly mechanical ventilation.
- Patients should be monitored for bacteremia and complications like respiratory failure.
Prognosis and Complications
- Prognosis varies based on adherence to treatment, coexisting conditions (pulmonary hypertension, cardiovascular diseases), and overall disease management.
- Tools like the BODE index assess mortality risk based on BMI, airflow obstruction, dyspnea, and exercise capacity.
- Common complications: acute exacerbations, respiratory failure, pulmonary hypertension, and weight loss.
Interprofessional Team Role
- Effective COPD management requires collaboration among pulmonologists, primary care providers, respiratory therapists, and palliative care experts.
