COPD is a progressive disease with inflammation as a key process
1. Snoeck-Stroband JB et al. Respir Res 2006; 7: 140. 2. Parr DG et al. Respir Research 2006; 7: 136 (online journal). Understanding inflammation Airway inflammation negatively affects health status of COPD patients 1 Higher levels of certain inflammatory markers are associated with a decline in lung function and subsequent disease progression 2
Airway inflammation is characterised by increased numbers of neutrophils, macrophages and CD8+ lymphocytes 1,2 Infiltration of inflammatory cells into the airways occurs in both early and late stages of COPD 3 As the disease progresses, the small airways fill with inflammatory mucus exudates 3 The presence of inflammation in the airways provides a rationale for using inhaled corticosteroids and long-acting beta 2 -agonists to treat the disease 1. Gold Guideline http://goldcopd.com 2007. 2. Barnes NC et al. Am J Respir Crit Care Med 2006; 173: 736–743. 3. Hogg JC et al. New Eng J Med 2004; 350: 2645–2653. Inflammation is present even in the early stages of COPD

The Anti-inflammatory Effect Is Associated With A Reduced Rate In The FEV1 Decline Ann Intern Med. 2009;151:517-527.

Calverley PMA et al. Lancet 2003; 361: 449 – 456. 5. Calverley PMA et al. New Eng J Med 2007; 356: 775–789. 6. Johnson M. Proc Am Thor Soc 2004; 1: 200–206 7. Adcock IM. J Allergy Clin Immunol 2002; 110(6 Suppl): s261–s268. Synergistic effects of SFC Bourbeau et al suggest that combination therapy has anti-inflammatory effects, not seen with inhaled corticosteroids alone 1 Compared with monotherapy, enhanced effects for combination are consistent not only with clinical data but also with in vitro data 2–5 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 level 1 Corticosteroids may regulate 2 receptor function by increasing expression of the receptor, and inhibiting 2 receptor down-regulation 6,7
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.
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 Summary of data of different therapeutic studied in patients with COPD
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?
COPD 2013 Roflumilast – this is a PDE-4 inhibitor (PDE-4 inhibition decreases inflammation and promotes airway smooth muscle relaxation) Approved for COPD patients with a history of exacerbations – the experience is limited, but this agent may be useful perhaps not only in COPD, but in asthma, bronchiectasis, etc – time will tell Mucoactive agents- the jury is out, but some patients may improve, some even think that they are better than the inhaled medications (but this is doubtful)

PA:A ratio of more than 1 at baseline was associated with future exacerbations of COPD, particularly those requiring hospitalization 23 The PA:A ratio also appears to outperform many established risk factors for exacerbation including GERD, SGRQ score, breathlessness, chronic bronchitis, and FEV1,as well as recently identified CT predictors.

Conclusions The burden of COPD is high and is rising 1 COPD is a multicomponent disease with inflammation at its core 2 It is important to treat the underlying inflammation, which is present even in the early stages of the disease 3,4 Patients on SFC have significantly improved lung function and quality of life, and a significant reduction in exacerbations compared with components or placebo 5 1.

Conclusions Exacerbations are common. 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
Rationale for combining long-acting bronchodilators Inhaled bronchodilators are the foundation of COPD treatment Most patients with COPD improve with bronchodilation Maximal bronchodilation is not achieved using clinically approved doses of 1 class of bronchodilator alone There could be synergistic interactions between 2-agonists and anticholinergics Cazzola M, Molimard M.

Astra Zeneca – PATHOS Study Objectives: – To investigate exacerbation rates in primary care patients with COPD treated with BF vs FS. Methods: – Data from primary care medical records. – Pairwise (1:1) propensity score matching. Results – Matching of 9893 patients (7155 BF; 2738 FS yielded two cohorts of 2734 patients), comprising 19,170 patient-years. – The exacerbation rates were 0.80 and 1.09 per patient-year BF and FS – Yearly rates for COPD-related hospitalizations were 0.15 and 0.21, respectively Conclusions – Long-term treatment with fixed-combination BF was associated with fewer exacerbations than FS in patients with moderate and severe COPD.
