Tissue Regeneration in Patients With Chronic Obstructive Pulmonary Disease After an Exercise Intervention. - Trial NCT06335992

Timeline & Enrollment

Primary Outcome

Pulmonary Function

Summary

The main objective of this project is to identify mechanisms for lung regeneration in
 patients with COPD induced by exercise training. The hypothesis is that adjusted exercise
 training improves disease outcome in these patients by decrease remodelling processes linked
 to oxidative stress, inflammatory and/or immunological pathways in the lung. Along the way,
 the investigator also expect to identify (or validate) biomarkers mirroring systemic
 processes such as reduced inflammation and ameliorating the epithelial barrier in these
 patients. These events may additionally act as potential targets for interventions.
 
 Objectives (i) Evaluate biomarkers for regenerative processes, matrix turnover, stem cell
 activity and inflammatory patterns in lung tissue biopsies, blood- and urine samples
 correlated to vital lung parameters and physical capacity, before and after attending an
 exercise-training program.
 
 (ii) Study the effects of exercise training on the pulmonary ventilation/perfusion ratio and
 quality of life.
 
 (iii) Evaluate the relation between pathophysiology in the lung evaluated by CT scan, and
 systemic response measured by muscle biopsies and biomarkers in blood/urine.
 
 (iv) Investigate in vitro cell behaviour and remodelling/regenerative processes altered in
 COPD patients upon exercise training (aim 1).
