2 PHARMACOLOGICAL MANAGEMENT OF COPD IN PATIENTS WITH CHRONIC CO-MORBIDITIES Professor Peter Calverley University Hospital Aintree Liverpool UK

3 A RUMSFELD MOMENT!  Does having COPD influence the choice of therapy for a co-morbidity?  Does taking a treatment for a co-morbidity improve the outcome in COPD?  Does taking a treatment for COPD affect the co- morbidity?

4 BETA –BLOCKERS AND COPD  Good data for the benefits of selective beta- blockade in congestive heart failure, rate control of AF  Longstanding worry that beta-blockade might precipitate bronchospasm  So most people avoided beta-blockers in COPD  Now we have evidence for safety and a reason why this is the case

5 BETA-BLOCKERS, COPD AND VASCULAR SURGERY  1205 COPD patients, 462 receiving therapy with BB pre- surgery Van Gestel et al AJRCCM 2008

6 Why COPD is not asthma –bronchodilator testing is not helpful Change in FEV 1 (L), Post-bronchodilator Subject Group Percent Smoker Controls Percent Non-smoker Contr Percent COPD Subjects

7 THE STATIN STORY

8 STATINS AND COPD OUTCOMES IN LOW RISK PATIENTS Mancini et al JACC 2006

9 STATINS AND EXACERBATIONS Mortenson E et al Respir Res 2009

10 Systemic Effects of COPD: Target Organs Lung Infections Lung Cancer Weight loss Muscle weakness Osteoporosis Angina Acute coronary syndromes Depression Diabetes Metabolic syndrome Systemic Inflammation Oxidatitive Stress Depression Peptic ulceration/reflux Depression From W MacNee

11 TREATMENT AND COMPLICATIONS  Depression –common, often associated with fatigue. Interaction with therapy more likely with systemic treatment. Corticosteroids possibly – roflumilast unproven  Reflux – GI issues with theophyllines and PDEIV inhibitors  Metabolism and diabetes –ocs associated with hyperglycaemia but this is a feature of acute exacerbations. More data from roflumilast  Muscles

14 Weight loss  Noted as a self-reported finding more often with roflumilast  Not just confined to patients reporting GI intolerance  Monitored with regular weight measurement in pivotal one year trials  In one 6 month study bioimpedance data were available

15 Body weight over time in the studies with available data Body Weight [kg] placebo roflumilast 500µg  = kg (CI –2.4;-1.9) p < Timecourse: Mean change in kg Between Treatment Differences least-squares means from ANCOVA Weeks

Am J Respir Crit Care Med 2010;181:A4473. Weight loss associated with roflumilast was primarily fat mass -0.5 FFMI: Fat Free Mass Index; BMI: Body Mass Index

18 MUSCLES  Loss of muscle bulk vs weakness  A marker for more health care expense and mortality but the thresholds may vary  A clear relationship of weakness to ocs use long term –not seen with ics  Anabolic steroids reverse this process but only in people taking oral corticosteroids ( Kreutzberg E et al)

19 BONES AND INHALED CORTICSTEROIDS  Database associations but confounded by disease severity

30 CONCLUSIONS  Beta–blockers and other cardiac drugs are safe in COPD  Statins may improve COPD outcomes but proper trial data are needed  Oral therapies produce more GI upset, oral corticosteroids long term are hazardous  Inhaled corticosteroids do not seem to accelerate osteoporosis but some may induce pneumonia  LAMA and LABA treatment is safe in COPD – anti- inflammatory therapy may improve cardiac outcomes  On balance our treatments are more friend than foe
