  2. Definition of COPD (GOLD 2012) • Chronic obstructive pulmonary disease (COPD), a common preventable and treatable disease, is • characterized by persistant airflow limitation: • not fully reversible • usually progressive • associated with an enhanced chronic inflammatory response in the airways and the lungs to noxious particles or gases. • Comorbidities and exacerbations contribute to the overall severity in individual patients. www.goldcopd.org

  12. Medical Research Council (mMRC) Dyspnea Score Dyspnea was defined as a score of 2 or higher on mMRC scale Airflow limitation: (FEV1) mMRC 4: I am to breathless to leave the house…; mMRC 3: I stop for breath after walking about 100 yards…; mMRC 2: I walk slower than other people…; mMRC 1: Short of breath when hurrying; mMRC 0: Breathless with strenuous exercise Adapted from Jones P. et al, ERJ 2011; 34: 29-35

  13. Aims of the COPD Assessment Test (CAT) CAT: a patient-completed questionnaire a short, simple and reliable test: • To improve the assessment of COPD patients • To grade the impact of COPD on health status. Jones P. et al, ERJ 2009; 34: 648-654.

  24. ECLIPSE study:Evaluation of COPD Longitudinally to Identify Predictive Surrogate Endpoints

  25. The ECLIPSE Study: Objectives of this 3-yrs observational study To define clinically relevant COPD subtypes in individuals with GOLD stage II–IV COPD To define the parameters that predict disease progression over 3 years in the clinically relevant COPD subtypes To acquire data on known clinical biomarkers in order to identify those that correlate with clinically relevant COPD subtypes To identify novel genetic factorsand/or biomarkers that correlate with clinically relevant COPD subtypes and with markers of disease progression Vestbo J, et al. Eur Respir J. 2008;31:869-873

Eur Respir J. 2008;31:869-873.

  27. Definition of COPD exacerbationaccording to GOLD guidelines An exacerbation of COPD is: • “an acute event characterized by a worsening of the patient’s respiratory symptoms that is beyond normal day-to-day variations and leads to a change in medication.” www.goldcopd.org

  28. The ‘frequent exacerbator phenotype’: ECLIPSE Susceptibility to Exacerbation in Chronic Obstructive Pulmonary Disease John R. Hurst, Jørgen Vestbo, Antonio Anzueto, Nicholas Locantore, Hana Mϋllerova, Ruth Tal-Singer, Bruce Miller, David A. Lomas, Alvar Agusti, William MacNee, Peter Calverley, Stephen Rennard, Emiel F.M. Wouters and Jadwiga A. Wedzicha New England Journal of Medicine 2010;363:1128-38 Hurst JR, et al. N Engl J Med. 2010;363:1128-38.

  29. The ‘frequent exacerbator phenotype’: ECLIPSE: Introduction • Background • Exacerbations of COPD are a major part of the natural history of COPD: • Accelerate decline in lung function • Reduce physical activity and QoL • Increase risk of hospitalization and death • Increased significantly healthcare costs • Rationale • The ECLIPSE cohort was used to test the hypothesis of a frequent exacerbation phenotype Is the most reliable predictor of exacerbations in an individual patient a history of prior exacerbations? Hurst JR, et al. N Engl J Med. 2010;363:1128-38 29

  30. The ‘frequent exacerbator phenotype’: ECLIPSEFrequency/Severity of Exacerbations by GOLD stage (1) p<0.01 Exacerbations are more frequent and more severe with increasing COPD severity What are the predictors of exacerbation frequency? Hospitalised for exacerbation in yr 1 Frequent exacerbations (2 or more) ECLIPSE 1 year data Hurst et al. N Engl J Med 2010

  31. The ‘frequent exacerbator phenotype’: ECLIPSE: Stability of the Exacerbator Phenotype 71% of Frequent Exacerbators in Year 1 and Year 2 were Frequent Exacerbators in Year 3 74% of patients having no exacerbations in Years 1 and Year 2 had no exacerbations in Year 3 ECLIPSE 3 year data Hurst JR, et al. N Engl J Med. 2010;363:1128-38.

  32. Conclusions (1) “Airflow limitation alone does not provide an accurate measure of disease severity or activity” • ECLIPSE and HEED confirm • Disease severity (breathlessness, exercise capacity, exacerbations, health status degradation) increases with GOLD stage • FEV1 poorly related with other parameters • COPD is highly heterogeneous • Within GOLD stage there is substantial variation in: • Breathlessness • Exercise capacity • Exacerbation frequency • Health status New GOLD guidelines must include other parameters: QoL, symptoms and exacerbation rate 32 Agusti A, et al. Resp Res. 2010;11:122

  33. Conclusions (2) ECLIPSE confirms Exacerbations become more frequent and more severe as COPD severity increases Frequent exacerbator is an independent disease phenotype That can be identified by patient self-report about previous exacerbations Stable over time (3 yrs) Patients with moderate COPD may be frequent exacerbators (22%) Exacerbation in prior year is the best predictor of occurrence of exacerbation Exacerbation rate must be integrated in GOLD guidelines

  47. Take home message • COPD is highly heterogeneous (HEED and ECLIPSE) • Former management of COPD (GOLD 2007): Unidimensionalapproach: spirometry: FEV1 (FEV1/FVC):  Diagnosis • New management of COPD (GOLD 2012): Multidimensionalapproach: FEV1; mMRC, CAT and exacerbations  Diagnosis (and phenotyping)  Prognosis  Monitoring Aim: Optimal Management and Treatment • ICS/LABA combination is effective in COPD patient groups C and D
