Study summary

The purpose of this study is to investigate the role of the pulmonary vasculature in the development and progression of chronic obstructive pulmonary disease (COPD). To accomplish this, an inhaled prostacyclin (iloprost) will be given to patients with COPD and changes in oxidative stress and lung volumes during exercise will be measured.

Read the detailed description

Chronic obstructive pulmonary disease (COPD), the 3rd leading cause of death in the US, is a progressive disorder for which new treatments are urgently needed, as existing therapies are focused primarily on symptom relief. Oxidative stress, in part arising from inducible nitric oxide synthase (iNOS) released by the pulmonary vasculature, is critical for the development and progression of COPD; a treatment strategy focused on the pulmonary vasculature is hypothesized to be beneficial in COPD patients. This will be studied with the use of an inhaled prostacyclin analogue, iloprost, which has been approved for pulmonary hypertension and investigated in small studies of COPD patients. Potential mechanisms include reductions in dynamic hyperinflation during exercise in COPD patients or improvements in oxidative stress

What researchers measure

Primary outcomes

  1. Dynamic hyperinflation during maximal cardiopulmonary exercise test

    Dynamic hyperinflation will be measured as EELV/TLC ratio (end-expiratory lung volume/total lung capacity ratio) during exercise

    Time frame: Acute response (exercise testing performed 30 minutes after study drug administration)

Secondary outcomes

  1. Blood markers of oxidative stress

    8-isoprostane, superoxide dismutase, catalase, nitrite, malondialdehyde

    Time frame: Acute response (measured 10 minutes, 30 minutes, 40 minutes, and 100 minutes after study drug administration)

  2. Blood markers of inflammation

    IL-1 beta, IL-6, IL-8, IL-10, IL-13, IL-18, TNF-alpha

    Time frame: Acute response (measured 10 minutes, 30 minutes, 40 minutes, and 100 minutes after study drug administration)

  3. Dead space fraction

    Time frame: Acute response (measured every 2 minutes during exercise, starting 30 minutes after study drug administration)

  4. B-type natriuretic peptide

    Time frame: Acute response (measured 30 and 40 minutes after study drug administration)

  5. Partial pressure of oxygen

    Time frame: Acute response (measured 30 minutes after study drug administration and every 2 minutes during exercise)

  6. Metabolic and gas exchange parameters during cardiopulmonary exercise test

    Time frame: Acute response (throughout exercise, starting 30 minutes after study drug administration)

  7. Blood cyclic AMP levels

    Time frame: Acute response (measured 10 minutes, 30 minutes, 40 minutes, and 100 minutes after study drug administration)

  8. Blood iloprost levels

    Time frame: Acute response (measured 10 minutes, 30 minutes, 40 minutes, and 100 minutes after study drug administration)

  9. Exercise time and external work performed

    Time frame: measured during exercise test 30 minutes after study drug administration

  10. Borg dyspnea and leg scores

    Time frame: During exericse (starting 30 minutes after study drug administration)
