Study of the Effects of Education on Patients With Chronic Obstructive Pulmonary Disease
The investigators hypothesize that education will improve exercise capacity, symptoms and quality of life in patients with chronic obstructive pulmonary disease (COPD). In addition, the investigators are interested in determining how education might alter various chemicals in the blood and exhaled breath that reflect inflammation in the lungs and the body as a whole.
The investigators plan to enroll 42 patients into this study, with half of them participating at each of the two sites, Vermont Lung Center at the University of Vermont in Burlington, Vermont, and at Baylor College of Medicine in Houston, Texas. Participants will undergo a series of measurements and tests at the beginning of the study, receive formal education about COPD over the next 2 weeks, return at 6 weeks for a brief refresher session, and finally return after 12 weeks for repeat measurement and testing as was done at the beginning. Participants will be asked to keep a diary of symptoms, medication, and exercise during the study.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Exercise tolerance
Time Frame: 12 weeks
|
Exercise tolerance will be measured by 6 min walk distance at baseline and again after 12 weeks of the intervention
|
12 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Dynamic hyperinflation
Time Frame: 12 weeks
|
Dynamic hyperinflation will be measured by changes in inspiratory capacity that occur before and after the 6 min walk test, at baseline, and then again at 12 weeks.
|
12 weeks
|
Oxidative stress
Time Frame: 12 weeks
|
Oxidative stress will be measured by levels of H2O2, 8-isoprostane, and glutathione in exhaled breath condensate at baseline and again at 12 weeks.
|
12 weeks
|
Systemic inflammation
Time Frame: 12 weeks
|
Systemic inflammation will be assessed by plasma levels of CRP, IL-6 and red cell distribution width at baseline and at 12 weeks.
|
12 weeks
|
Lung mechanics
Time Frame: 12 weeks
|
Lung mechanics will be assessed by measurement of respiratory system impedance using the forced oscillation technique at baseline and at 12 weeks.
|
12 weeks
|
Dyspnea
Time Frame: 12 weeks
|
Dyspnea will be assessed by questionnaires (Borg, MRC, BDI/TDI) at baseline and at 12 weeks.
|
12 weeks
|
Quality of Life
Time Frame: 12 weeks
|
Quality of life will be assessed by the St. George Respiratory Questionnaire at baseline and at 12 weeks.
|
12 weeks
