2 Incidence CDC data 7/2012 CDC data 7/2012 COPD is now 3 rd leading cause of death COPD is now 3 rd leading cause of death 2008 141,075 2008 141,075 46.4 men@100,000 46.4 men@100,000 34.2 women@100,000 34.2 women@100,000

3 Incidence Male mortality is down from 49@100,000 Male mortality is down from 49@100,000 Female mortality unchanged from 2007 Female mortality unchanged from 2007 75% of patients with COPD are between 40 and 65 75% of patients with COPD are between 40 and 65 There are an estimated 24,000,000 US patients. There are an estimated 24,000,000 US patients. More women die annually. More women die annually.

4 Proposed Pathophysiology of COPD Young, Euro Resp Rev, 2009

5 Pathophysiology of COPD Cigarette smoking, inhaled aerosols, genetic predisposition Cigarette smoking, inhaled aerosols, genetic predisposition Inflammatory process in bronchial lumen release IL-8, sequester polys Inflammatory process in bronchial lumen release IL-8, sequester polys Macrophages plus IL-8 cause poly elastace release Macrophages plus IL-8 cause poly elastace release Elastin is destroyed, tissue protective protease destroyed Elastin is destroyed, tissue protective protease destroyed Young, Euro Resp Rev, 2009

6 Pathophysiology of COPD CD-8 and T lymphocytes migrate CD-8 and T lymphocytes migrate Oxidative load crosses back into vascular endothelium Oxidative load crosses back into vascular endothelium Combines with circulating cytokines Combines with circulating cytokines Systemic vascular damage and endothelial dysfunction occurs Systemic vascular damage and endothelial dysfunction occurs Young, Euro Resp Rev, 2009

7 Pathophysiology of COPD Nicotine releases fibronectin causing increased focal airway fibrosis and collagen release damaging injury repair. Nicotine releases fibronectin causing increased focal airway fibrosis and collagen release damaging injury repair. Cellular apoptosis is diminished prolonging cell life of polys and macros leading to further cell mediated injury.

8 Pathophysiology Reactive Oxidative species “spill over” into circulation and cause systemic effects Reactive Oxidative species “spill over” into circulation and cause systemic effects Muscle wasting, weakness, anemia, weight loss, osteoporosis, and premature aging of the lungs Muscle wasting, weakness, anemia, weight loss, osteoporosis, and premature aging of the lungs

9 Relationship between COPD and Lung Cancer 60-90% of lung cancers develop in patients w/COPD 60-90% of lung cancers develop in patients w/COPD May share common inflammatory pathways May share common inflammatory pathways Increased levels of guanine triphosphate, growth factor and epithelial mesenchymal transition may lead to DNA changes and Cancer Increased levels of guanine triphosphate, growth factor and epithelial mesenchymal transition may lead to DNA changes and Cancer

10 Epidemiology of COPD Only 20-30% of people develop COPD despite same exposure. Only 20-30% of people develop COPD despite same exposure. Genetic predisposition heavily affects the results. Genetic predisposition heavily affects the results. After 40 pack years, FEV1/FVC ratio will be 70% or less and will progressively decline in this susceptible population. After 40 pack years, FEV1/FVC ratio will be 70% or less and will progressively decline in this susceptible population.

11 FEV1 decline defines this subset Increased incidence compared with smokers with normal PFT’s Increased incidence compared with smokers with normal PFT’s Coronary artery disease Coronary artery disease Stroke Stroke Lung cancer Lung cancer

12 FEV1 decline and all cause CV mortality is related Increased levels IL6 Increased levels IL6 Increased levels CRP Increased levels CRP Increased levels TNF Increased levels TNF Once FEV1 and FEV1/FCC decline disease is progressive and no current approved treatment alters this course. Once FEV1 and FEV1/FCC decline disease is progressive and no current approved treatment alters this course. Studies now focused on suppressing inflammation.

13 Decreased Lung Function and the effects of statins Normal lung aging starting at age 25 is loss 0f 18 cc FEV1/year Normal lung aging starting at age 25 is loss 0f 18 cc FEV1/year Burrows (NEJM 1969) showed COPD patients loss 80 cc FEV1/year Burrows (NEJM 1969) showed COPD patients loss 80 cc FEV1/year Exacerbations increase loss 2-7cc more/year Exacerbations increase loss 2-7cc more/year Progression so far not preventable Progression so far not preventable

16 Mortality Outcomes in COPD Observational Studies Soyseth severe COPD 1.9 year study 43% less deaths in statin group Soyseth severe COPD 1.9 year study 43% less deaths in statin group Frost 77,322 patients over 11 years 38% death reduction in all doses, 81% reduction in moderate dose. Frost 77,322 patients over 11 years 38% death reduction in all doses, 81% reduction in moderate dose. Mortenson 46% risk of death reduction following pneumonia hospitalization Mortenson 46% risk of death reduction following pneumonia hospitalization

Did this affect earlier study outcomes? Death from any cancer reduced in all 3 of his groups 13.9 in high dose, 17 in low dose v. 26 in control group/100 patient years Death from any cancer reduced in all 3 of his groups 13.9 in high dose, 17 in low dose v. 26 in control group/100 patient years Karp Am J Med 2008, vol100, p302-9

22 Statins in Community Acquired Pneumonia All showed decreased ICU transfer, decreased death and improved outcomes All showed decreased ICU transfer, decreased death and improved outcomes Some studies showed COPD patients some did not Some studies showed COPD patients some did not Statins must be maintained during hospitalization Statins must be maintained during hospitalization Improved outcomes occurred also if statins were started on admission Improved outcomes occurred also if statins were started on admission

23 Conclusion Role of inflammation is increasingly recognized in many disease states. Role of inflammation is increasingly recognized in many disease states. Statins effects on COPD exacerbations, outcomes in infections, and on companion diseases of Cancer, CAD and Strokes were discussed. Statins effects on COPD exacerbations, outcomes in infections, and on companion diseases of Cancer, CAD and Strokes were discussed. While pathophysiology is further studied, better outcomes are available now. While pathophysiology is further studied, better outcomes are available now.
