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.
