PHARMACOLOGICAL MANAGEMENT OF COPD IN PATIENTS WITH CHRONIC CO-MORBIDITIES Professor Peter Calverley University Hospital Aintree Liverpool UK 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? 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 BETA-BLOCKERS, COPD AND VASCULAR SURGERY 1205 COPD patients, 462 receiving therapy with BB pre- surgery Van Gestel et al AJRCCM 2008 Why COPD is not asthma –bronchodilator testing is not helpful 30 Percent 25 20 15 10 5 35 30 25 Percent Smoker Controls 0 20 15 10 5 0 35 30 25 Percent Non-smoker Contr Subject Group COPD Subjects 35 20 15 10 5 0 -0.65 -0.55 -0.45 -0.35 -0.25 -0.15 -0.05 0.05 0.15 0.25 0.35 0.45 0.55 0.65 0.75 0.85 Change in FEV1 (L), Post-bronchodilator 0.95 1.05 1.15 1.25 1.35 THE STATIN STORY STATINS AND COPD OUTCOMES IN LOW RISK PATIENTS COPD/Low Risk Hospitalization 0.87 (.76, 1.0), 0.78 (.64, .95), 0.65 (.55, .78), for COPD p = .0502 p = .015 p < .0001 Hospitalization for COPD ACE Inhibitor ARB Statin 0.74 (.59, .92), p = .0062 Combination Myocardial Infarction 0.97 (.63, 1.50) 0.96 (.53, 1.73) 0.87 (.51, 1.49) 0.87 (.49, 1.54) Death 0.60 (.49, 0.52 (.38, 0.56 (.42, 0.38 (.27, .73), .72), .74), .54), p p p p < < < < ACE Inhibitor ARB Statin Combination ACE Inhibitor .0001 .0001 .0001 .0001 ARB Statin Combination (.59, (.49, (.51, (.36, .85), .84), .83), .66), p p p p = = = < 0.0 (.84, (.78, (.67, (.62, .99), .96), .81), .80), p p p p = = < < .0260 .0056 .0001 .0001 Myocardial Infarction 1.17 (.90, 1.52) 1.10 (.79, 1.54) 0.85 (.61, 1.18) 1.27 (.90, 1.78) Death 0.73 (.65, 0.55 (.46, 0.51 (.43, 0.35 (.28, .83), .66), .62), .44), p p p p < < < < .0001 .0001 .0001 .0001 Myocardial Infarction or Dea Myocardial Infarction or Death 0.71 0.64 0.65 0.49 0.91 0.86 0.74 0.70 ACE Inhibitor .0002 .0011 .0006 .0001 ARB Statin Combination 0.5 1.0 1.5 0.82 0.68 0.64 0.48 (.73, (.58, (.55, (.40, 2.0 Risk Ratio Mancini et al JACC 2006 .92), .80), .75), .58), p p p p = < < < 0.0 .0008 .0001 .0001 .0001 STATINS AND EXACERBATIONS Mortenson E et al Respir Res 2009 Angina Acute coronary syndromes Systemic Effects of COPD: Target Organs Lung Infections Lung Cancer Weight loss Muscle weakness Diabetes Metabolic syndrome Osteoporosis Peptic ulceration/reflux Systemic Inflammation Oxidatitive Stress From W MacNee Depression Depression 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.
