Study of the Effects of Education on Patients With Chronic Obstructive Pulmonary Disease

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

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.

Further study details as provided by David Kaminsky, MD, University of Vermont:

Primary Outcome Measures:
  • 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

Secondary Outcome Measures:
  • 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.

  • 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.

  • 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.

  • 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.

  • Dyspnea [ Time Frame: 12 weeks ]
    Dyspnea will be assessed by questionnaires (Borg, MRC, BDI/TDI) at baseline and at 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.
