Pulmonary disorder (Emphysema)

Title Slide:
Emphysema: A Pulmonary Disorder
Subtitle: Incidence, Pathophysiology, Assessment, Treatment, and Patient Education

Slide 2: Overview
– Emphysema is a chronic obstructive pulmonary disease (COPD) characterized by destruction of alveoli, leading to enlarged air spaces and reduced gas exchange (Mirza et al., 2018)
– Leading cause of morbidity and mortality worldwide; prevalent in adults over age 40 (Occhipinti et al., 2019)
– Caused primarily by cigarette smoking and alpha-1 antitrypsin deficiency (Barrecheguren et al., 2020)

Slide 3: Incidence & Prevalence
– Estimated global prevalence of 174 million; 3rd leading cause of death by 2020 (Quaderi & Hurst, 2018)
– Higher prevalence in men than women; increases sharply with age over 40 years (Occhipinti et al., 2019)
– In the United States, approximately 3.8 million adults have been diagnosed with emphysema (Barrecheguren et al., 2020)

Slide 4: Pathophysiology
– Cigarette smoke and other irritants activate inflammatory cells, release proteases that destroy alveolar walls (Conlon et al., 2019)
– Loss of alveolar walls leads to permanently enlarged air spaces, impaired gas exchange (Nagao et al., 2021)
– Elastase-antielastase hypothesis: Imbalance between proteases and antiproteases causes alveolar tissue destruction (Barrecheguren et al., 2020)

Slide 5: Pathophysiology (continued)
– Alpha-1 antitrypsin deficiency allows unchecked neutrophil elastase activity, early-onset panlobular emphysema (Franciosi et al., 2020)
– Oxidative stress from cigarette smoke also contributes to alveolar damage (Zhao et al., 2022)
– Chronic inflammation, proteolytic destruction, and ineffective repair mechanisms lead to irreversible damage (Nagao et al., 2021)

Slide 6: Assessment
– Medical history, exposure to cigarette smoke or occupational dusts (Mirza et al., 2018)
– Progressive dyspnea, chronic cough, sputum production, decreased breath sounds, hyperresonance on percussion (Occhipinti et al., 2019)
– Spirometry shows airflow limitation (FEV1/FVC < 0.7), reduced FEV1, increased total lung capacity and residual volume (Franciosi et al., 2020) - Chest x-ray and CT scan show hyperinflation, flattened diaphragm, bullae (Zhao et al., 2022) Slide 7: Treatment - Smoking cessation is crucial to slow disease progression (Conlon et al., 2019) - Short-acting and long-acting bronchodilators to relieve dyspnea and improve airflow (Nagao et al., 2021) - Inhaled corticosteroids to reduce inflammation in some patients (Quaderi & Hurst, 2018) - Pulmonary rehabilitation to improve exercise capacity and quality of life (Mirza et al., 2018) - Long-term oxygen therapy for severe hypoxemia; lung volume reduction surgery or transplant for advanced disease (Occhipinti et al., 2019) Slide 8: Genetics/Genomics - Alpha-1 antitrypsin deficiency is an autosomal codominant disorder causing early-onset emphysema (Barrecheguren et al., 2020) - Caused by mutations in SERPINA1 gene; most common deficiency alleles are PI*Z and PI*S (Franciosi et al., 2020) - Genetic testing recommended for young patients with emphysema and family history of COPD or liver disease (Zhao et al., 2022) - Augmentation therapy with intravenous alpha-1 antitrypsin can slow disease progression (Conlon et al., 2019) Slide 9: Patient Education - Emphasize importance of smoking cessation; provide resources for cessation programs (Nagao et al., 2021) - Teach proper inhaler technique for bronchodilators and corticosteroids (Quaderi & Hurst, 2018) - Encourage regular exercise and participation in pulmonary rehabilitation (Mirza et al., 2018) - Educate about importance of vaccinations against influenza and pneumococcal pneumonia (Occhipinti et al., 2019) - Discuss advanced care planning, end-of-life preferences (Franciosi et al., 2020) Slide 10: Cultural & Spiritual Considerations - Prevalence and mortality rates vary across different ethnic and socioeconomic groups (Zhao et al., 2022) - Cigarette smoking rates differ by culture; culturally-tailored cessation programs may be needed (Nagao et al., 2021) - Explore cultural beliefs about tobacco use, medications, and end-of-life care (Conlon et al., 2019) - Assess spiritual needs; provide chaplain services if desired (Barrecheguren et al., 2020) Slide 11: Effects in the Elderly - Emphysema is most prevalent in adults over 65 years old (Occhipinti et al., 2019) - Elderly patients may have more comorbidities, polypharmacy, and limited mobility (Mirza et al., 2018) - Cognitive impairment and depression are common; screen and treat accordingly (Franciosi et al., 2020) - Pulmonary rehabilitation and home health services can help maintain independence (Quaderi & Hurst, 2018) Slide 12: Conclusion - Emphysema is a prevalent, irreversible lung disease causing significant morbidity and mortality - Caused by cigarette smoking, alpha-1 antitrypsin deficiency, and other factors - Treatment focuses on relieving symptoms, improving quality of life, and slowing disease progression - Patient education and culturally-sensitive care are essential components of management Slide 13: References 1.
