Venezuela (Caracas) Brazil (São Paulo) Chile (Santiago) Uruguay (Montevideo) Menezes A, et al. Lancet 2005 COPD is a progressive disease with inflammation as a key process Understanding inflammation • Airway inflammation negatively affects health status of COPD patients1 • Higher levels of certain inflammatory markers are associated with a decline in lung function and subsequent disease progression2 1. Snoeck-Stroband JB et al. Respir Res 2006; 7: 140. 2. Parr DG et al. Respir Research 2006; 7: 136 (online journal). Inflammation is present even in the early stages of COPD • Airway inflammation is characterised by increased numbers of neutrophils, macrophages and CD8+ lymphocytes1,2 • Infiltration of inflammatory cells into the airways occurs in both early and late stages of COPD3 • As the disease progresses, the small airways fill with inflammatory mucus exudates3 • The presence of inflammation in the airways provides a rationale for using inhaled corticosteroids and long-acting beta2-agonists to treat the disease 1.

Synergistic effects of SFC • Bourbeau et al suggest that combination therapy has anti-inflammatory effects, not seen with inhaled corticosteroids alone1 • Compared with monotherapy, enhanced effects for combination are consistent not only with clinical data but also with in vitro data2–5 • Bourbeau et al propose that the anti-inflammatory activity seen with SFC but not FP may be due to additive or synergistic effects at the receptor level1 • Corticosteroids may regulate 2 receptor function by increasing expression of the receptor, and inhibiting 2 receptor down-regulation6,7 1.

COPD 2013 • “patients who benefit the most from inhaled bronchodilators seem to be those who have respiratory symptoms and airflow obstruction with an FEV1 less than 60% predicted” • “monotherapy using either long acting inhaled anticholinergics or long acting beta agonists(but not inhaled steroids as monotherapy) for symptomatic patients with an FEV1 of less than 60% predicted is recommended Courtesy of Frank Perez-Guerra, M.D. Summary of data of different therapeutic studied in patients with COPD • UPLIFT (Tiotropium achieves improvement in lung function over time, although rate of decline not reduced; reduction in frequency of exacerbations and in hospitalizations; no difference in mortality between tiotropium and placebo • TORCH- reduction in the rate of decline in airflow limitation in the salmeterol/fluticasone arm compared to placebo • INSPIRE – comparison of SFC versus tiotropium in severe COPD – no difference in exacerbation frequency between the two treatments. Question of better quality of life and reduced mortality risk with SFC. Summary of data of different therapeutic studied in patients with COPD • Tiotropium/formoterol (Foradil) vs salmeterol(Serevent)/fluticasone in moderate COPD – TF superior in lung function over the day compared to SF (this study appeals to me, Chest 2008;134:255) • OPTIMAL (Tiotopium/placebo, T plus salmeterol, T plus salmeterol/fluticasone) – patients treated with T/F/S had significantly better disease specific quality of life and fewer hospitalizations compared to T/placebo, however these improvements in health outcomes were associated with increased costs. Monotherapy with T most economically attractive. Exacerbation rate did not differ Others therapy • Immunizations – both Pneumovax and influenza (this is an “accepted” recommendation) • Testing for alpha-one-anti-trypsin deficiency – • Lung volume reduction surgery (or “medical treatment utilizing valves”) - not a common procedure, but may be considered in very symptomatic patients with well documented predominant upper lobe emphysema with an FEV1 and DlCO of more than 20% of predicted • Transplantation - LVRS may be a bridge to this. When to refer – BODE index of over 5, post dilator FEV1 of less than 20% predicted, resting hypoxemia, hypercapnia, secondary PH, accelerated decline in FEV1 – but…is there a survival benefit?

Patients with previous exacerbations are more likely to have more. Presence of cough and sputum production are associated with more exacerbations • Antibiotics are useful to treat exacerbations in patients with mild to moderate COPD • Prednisone 40 mg daily for 5 days is enough • Use of β-blockers in patients with HF, even non selective are well tolerated and may be associated with improve survival 38 COPD : a vision for the next 10 years Understanding Improved New airway obstruction drug delivery LABAs and LAMAs Combinations LAMA + LABA Ultra long-acting β2 agonists under development Vilanterol Olodaterol Abediterol (LAS-100977) AZD3199 PF-610355 (?)
