2 Definition of COPD COPD is a preventable and treatable disease with some significant extra pulmonary effects that may contribute to the severity in individual patients. Healthy Alveolus The airflow limitation is usually progressive associated with an abnormal inflammatory response of the lung to noxious particles or gases. COPD

3 Of the six leading causes of death in the United States, only COPD has been increasing steadily since Source: Jemal A. et al. JAMA

4 COPD Mortality by Gender, U.S., Number Deaths x Men Women

5 COPD Mortality Worldwide Ischaemic heart dis Cerebrovascular dis Lower resp infection Diarrhoeal disease Perinatal disorders COPD Tuberculosis Measles Road Traffic Accidents Lung Cancer 6th rd Stomach Cancer HIV Suicide Source: Murray & Lopez. Lancet 1997

7 Classification of COPD Severity by Spirometry (2008) Stage I: Mild FEV 1 /FVC < 0.70 FEV 1 > 80% predicted Stage II: Moderate FEV 1 /FVC < % < FEV 1 < 80% predicted Stage III: Severe FEV 1 /FVC < % < FEV 1 < 50% predicted Stage IV: Very Severe FEV 1 /FVC < 0.70 FEV 1 < 30% predicted or FEV 1 < 50% predicted plus chronic respiratory failure 6

12 GOALS of COPD MANAGEMENT Relieve symptoms Prevent disease progression Improve exercise tolerance Improve health status Prevent and treat complications Prevent and treat exacerbations Reduce mortality 01

13 Therapy at Each Stage of COPD I: Mild II: Moderate III: Severe IV: Very Severe FEV 1 /FVC < 70% FEV 1 /FVC < 70% FEV 1 /FVC < 70% 50% < FEV 1 < 80% predicted ı ı FEV 1 /FVC < 70% 30% < FEV 1 < 50% predicted ı FEV 1 < 30% predicted or FEV 1 < 50% predicted plus chronic respiratory failure FEV 1 > 80% predicted Active reduction of risk factor(s); influenza vaccination Add short-acting bronchodilator (when needed) Add regular treatment with one or more long-acting bronchodilators (when needed); Add rehabilitation Add inhaled glucocorticosteroids if repeated exacerbations Add long term oxygen if chronic respiratory failure. Consider surgical treatments

14 Early Therapy Improves Outcomes of Exacerbations of Chronic Obstructive Pulmonary Disease Wilkinson et al. AJRCCM 2004 Effect of early treatment on recovery of exacerbation symptoms

15 Severe acute exacerbations and mortality in patients with COPD Soler-Cataluña et al. THORAX 2005 Kaplan-Meier survival curves by severity of exacerbations in patients with COPD: (1) no acute exacerbations of COPD (2) patients with acute exacerbations of COPD requiring emergency service visits without admission (3) patients with acute exacerbations of COPD requiring one hospital admission; (4) patients with readmissions

16 COPD EXACERBATIONS An event in the natural course of the disease characterized by a change in the patient s baseline dyspnea, cough, and/or sputum that is beyond normal day-to-day variations, is acute in onset, and may warrant a change in regular medication in a patient with underlying COPD.

17 COPD EXACERBATIONS- Precipitating factors Infections (respiratory and nonrespiratory) Exposure to respiratory irritants and air pollution Co-morbid diseases (CHF, PE, IHD, Pneumothorax)

18 Severe acute exacerbations and mortality in patients with COPD Soler-Cataluña et al. THORAX 2005 ı Kaplan-Meier survival curves by frequency of exacerbations in patients with COPD: group A, patients with no acute exacerbations of COPD group B, patients with 1 2 acute exacerbations of COPD requiring hospital management group C, patients with 3 acute exacerbations of COPD

19 COPD EXACERBATIONS-Management Inhaled BD Treatment Systemic steroids (PO vs IV) Usually 2 weeks course Oxygen supply- at the lowest level needed Antibiotics No extensive evaluation for the cause of the exacerbation if it responds to initial treatment.

20 AE-COPD: Etiology 25% viruses 26% bacteria 27% combination of the two 22% other causes

21 COPD EXACERBATIONS-Management Inhaled BD Treatment Systemic steroids (PO vs IV) Usually 2 weeks course Oxygen supply- at the lowest level needed Antibiotics No extensive evaluation for the cause of the exacerbation if it responds to initial treatment.

22 Treatment failure of AE-COPD Change antibiotics with good coverage against P. aureginosa. Exclude Cor Pulmonale or CHF by Echo. Exclude PE and Pneumothorax Add aminophylline Exclude GERD

23 Pneumothorax in COPD Patients COPD is the most common cause for secondary spontaneous pneumothorax ı Due to rupture bleb hyperinflation mechanical ventilation Always in the DD of COPD Exacerbation CT scan should be perform in difficult cases. Definite treatment: VATS -pleurodesis

24 Core Pulmonale in COPD Causes Chronic alveolar hypoxemia Lung hyperinflation Increase blood viscosity Physical findings are late signs Peripheral edema is poorly correlated with RHF Echo measures of PAP are often inaccurate and may over diagnose pulmonary hypertension. No evidence to Anticoagulation Very important prognostic factor with 2 years survival less than 50% if PAP >45mmHg.

25 Co-morbidity in COPD l Cardiovascular morbidity. l Muscle wasting. l Osteoporosis. l Metabolic syndrome.

39 GOLD steps of management I Mild II Moderate III Severe IV Very severe FEV 1 /FVC <0.70 FEV 1 80% predicted FEV 1 /FVC < % FEV 1 <80% predicted Active reduction of risk factor(s); influenza vaccination Add short-acting bronchodilator (when needed) FEV 1 /FVC < % FEV 1 <50% predicted FEV 1 /FVC <0.70 FEV 1 <30% predicted or FEV 1 <50% predicted plus chronic respiratory failure Add regular treatment with one or more long-acting bronchodilators (when needed); Add rehabilitation Add inhaled glucocorticosteroids if repeated exacerbations GOLD guidelines. Add long-term oxygen if chronic respiratory failure Consider surgical treatments

40 Combination ICS/bronchodilator therapy - Triple therapy ıbackground An inhaled glucocorticosteroid combined with a long-acting β 2-agonist is more effective than the individual components in reducing exacerbations and improving lung function and health status ı(evidence A).

43 Management of Stable COPD Non-Pharmacologic Treatments Rehabilitation: All COPD patients benefit from exercise training programs, improving with respect to both exercise tolerance and symptoms of dyspnea and fatigue (Evidence A). Oxygen Therapy: The long-term administration of oxygen (> 15 hours per day) to patients with chronic respiratory failure has been shown to increase survival (Evidence A). 32

44 Pulmonary Rehabilitation Improve the dyspnea, exercise ability, health status. Minimal effects on PFTs. Multidiscipilinary program. Should be considered for patients with symptomatic COPD. For patients with moderate to severe COPD (FEV1<80%)

45 Maximal Exercise Capacity Walking distance - Endurance capacity Relief of symptoms ( dyspnea and fatigue) Quality of life Utilization of health care resources Mortality?

46 COPD Indications for Hospitalization ATS/ ERS Guidelines Sudden onset of new or severe symptoms Severe or very severe underlying COPD Onset of new physical findings (edema, change in mental status) Failure to respond to initial medical treatment Associated comorbidities Diagnostic uncertainty (pneumonia?
