  1. Prof. Attila Somfay Dept.Pulmonology, University of Szeged, Deszk, Hungary COPD

  2. 58-year-old male smoker Progradiating effort dyspnoe for 4 years Medical history: hypertension, recidiv stroke • Dg: CHF,hypertonia, hypertrigliceridaemia • Echocard.: LA:55, LV:46-23, EF:65%, dilated RV and RA

  3. Hospital admittance in Deszk • BMI: 39 • TG: 3 mM/L • Htk: 0.55 • Hgb: 165 g/L • Arterilabloodgas- PaO2: 57 mmHg - PaCO2:54 mmHg - pH:7,40

  5. Chronic obstructive bronchitis and emphysema chronic obstructive airway disease (COAD, COLD) (chronic obstructive pulmonary disease ) COPD

  6. COPD emphysema bronchitis „pink puffer” „blue bloater”

  7. CIBA Guest Symposium: Terminology, definitions and classifications ofchronic pulmonary emphysema and related conditions (1959) 1./ Obstructiveemphysema: abnormal permanent enlargement of the airspaces distal to the terminal bronchioles, accompanied by destruction of the alveolar walls and without obvious fibrosis. 2./ Chronic bronchitis: the presence of chronic productive cough for 3 months in each of 2 successive years in a patient in whom other causes (heart failure, tbc, bronchiectasis, tumor, lung abscess) of chronic cough have been excluded.

  8. 1. COPD, a common preventable and treatable disease, is characterized by persistent airflow limitation. 2. The airway obstruction is usually progessive and associated with an enhanced chronic inflammatory response in the airways and the parenchyma to noxius particles and gases. 3. Exacerbations and comorbidities contribute to the overall severity in an individual patient. GOLD 2011

  9. Percent Change in Age-Adjusted Death Rates, U.S. Proportion of 1965 Rate 3.0 Coronary Heart Disease Stroke Other CVD COPD All Other Causes 2.5 2.0 1.5 1.0 0.5 –59% –64% –35% +163% –7% 0 1965 - 1998 1965 - 1998 1965 - 1998 1965 - 1998 1965 - 1998

  10. „Global burden of disease” (Science 1996; 274:740-743.)

  11. Epidemiology 4-7% of adult population, 9-10 % for those over 40 Prevalence expected to rise 3x in 10 years. By 2020, it becomes the 3rd most frequent cause of death

  12. Mortality (Global Burden of Disease Study) Lozano, Lancet 2012 COPD death/ 100 000 77 44 inhabitant 1990 2010

  14. Etiology: host factors

  15. Etiology: acquired risk

  16. Effect of smoking on annual decline in lung functionFletcher C, Peto R: BMJ 1977:i: 1645

  17. Pathology 1. chronic bronchitis– increased mucus production, chronic cough

  18. 2. obstructiv bronchiolitis– small airway obstruction with inflammation and fibrosis of bronchioles

  19. 3. Emphysema– alveolar destruction, hiperinflation, loss of elastic recoil, gázcserezavar, bronchiálisobstrukció

  20. Small airways in COPD Barnes, NEJM,2004

  21. Loss of alveolar attachmentsin smokers Normal Smoker Saetta et al. ARRD 1985

  22. Airway muscle thicknessincreases in COPD Non-smoker COPD Saetta. 1998

  23. Causes of Airflow Limitation • Irreversible • Fibrosis and narrowing of the airways • Loss of elastic recoil due to alveolar destruction • Destruction of alveolar support that maintains patency of small airways

  24. Causes of Airflow Limitation • Reversible • Accumulation of inflammatory cells, mucus, and plasma exudate in bronchi • Smooth muscle contraction in peripheral and central airways • Dynamic hyperinflation during exercise

  25. Driving pressure(parenchyma) Airflowlimitation = Resistance(small airways)

  26. Pathology and gas exchange in COPD Stockley,Rennard, Rabe, Celli, 2007

  27. Differential diagnosis of airway obstruction Chronicbronchitis Emphysema COPD Airflow obstruction Asthma Adapted from Snider 1995

  28. Differencial diagnostics • Asthma • CHF • Bronchiectasis • Bronchiolitis obliterans (young, non-smoker, RA, smoke exposition, HRCT:hypodens area) • Diffuse panbronchiolitis (non-smoker malei, sinusitis, HRCT:centrilobular foci and hyperinflation)

  29. Inflammation and lung function In asthma and COPD Barnes, 2009 Overlap ~ 10 - 40%
