COPD clinical trials
Resting O2
- Lancet 1981
- resting O2 reduces mortality for pts with resting hypoxemia spO2<88
- LOTT trial 2016: no decrease in time to death or time to hospitalization
Uplift
- UPLIFT 2008
- tiotopium relieves dyspnea, improves lung function, quality of life, reduces exacerbation
- no significant difference in FEV1 decline or mortality
Torch
- TORCH 2007
- ICS/LABA improved lung function with FEV1 vs placebo vs LABA vs ICS
- no mortality benefit with combination therapy
React
- REACT 2015
- triple therapy with Roflumulast (long acting PDE4 inhibitor)
- population: severe COPD, chronic bronchitis, and at least 2 exacerbations
- significant reduction in exacerbations
- increased side effects: diarrhea, nausea, decreased appetite
Albert
- Albert 2011
- Chronic azithromycin
- population: pts with mod-severe COPD and either continuous O2 or at least on exacerbation in last year

MISC
Epidemiology
- 5% of the U.S. population
Pathophysiology
- airflow obstruction that's not reversible
- inflammatory condition
- cigarette smoke/irritants activate macrophage/epithelial cells
- neutrophil chemotactic factors released
- proteases destroys lung parenchyma
