Patients with Chronic Obstructive Pulmonary Disease are characterised by a sedentary lifestyle. This contributes to increase the number of hospitalizations and mortality. Changing this lifestyle is a major objective of the management of these patients. Pulmonary rehabilitation helps patients to increase their fitness, but modifying a longstanding sedentary habit is more difficult to achieve. This project aims at modifying patients' long term physical activity with a physical activity coaching programme. This will help patients to transform the benefits of pulmonary rehabilitation into a healthier active lifestyle and contribute to reduce hospitalizations, increase quality of life and survival.

People with mild chronic obstructive pulmonary disease (COPD) can have significant physiological abnormalities and breathing inefficiency which become more pronounced during the stress of exercise, leading to intolerable breathing discomfort (dyspnea). To better understand the mechanisms of respiratory symptoms and exercise limitation in mild COPD, we will examine detailed lung function tests and other important measurements during rest and exercise in people with mild COPD compared with healthy non-smokers. This will be the first study to uncover the fundamental causes of breathing inefficiency and the related shortness of breath during physical exertion in patients with mild COPD. We hope to demonstrate that one simple measurement during exercise [the relation (ratio) between the total amount of air breathed (ventilation) and the amount of carbon dioxide breathed out] gives meaningful information about the extent of damage to the small airways and blood vessels in mild COPD and the overall gas exchanging function of the lungs, without the need for an arterial blood sample. This is a case-controlled observational study not involving an intervention. Participants will complete 2 visits approximately 1 week apart, each conducted at the same time of day. Visit 1 will consiste of screening for iligibility, symptom and activity assessments, pulmonary function tests and an incremental cycle cardiopulmonary exercise test (CPET) for familiarization purposes. Visit 2 will include spirometry followed by an incremental cycle CPET with detailed measures of ventilatory, gas exchange, sensory-perceptual and arterial blood gas responses.
The study is an observational multicenter descriptive study. It is planned to enroll approximately 1250 subjects with severe and very severe COPD hospitalized for the reason of COPD exacerbation into departments of pulmonology or therapy. The study will be conducted in approximately 20-25 institutions of treatment and prevention in Russian Federation and will include about 50 to 60 subject at each clinical site.
A chronic dosing (24 weeks) study to assess the efficacy and safety GFF MDI; PT003), FF MDI; PT005, and GP MDI; PT001) in subjects with moderate to very severe COPD, compared with placebo.
The overall objective of this study is to evaluate a collaborative self-management intervention in patients with moderate to severe COPD in a primary care population. To achieve this objective the investigators developed a diagnostic and treatment pathway for the management of COPD in primary care that is based on national guidelines and focused on patient self-management.
Early changes associated with the development of smoking-induced diseases, e.g., COPD and lung cancer (the two commonest causes of death in U.S.) are often characterized by abnormal airway epithelial differentiation. Airway basal cells (BC) are stem/progenitor cells necessary for generation of differentiated airway epithelium. Based on our preliminary observations on SAE BC cells and FGFR2 signaling, we hypothesized that suppression of FGFR2 signaling in the SAE BC stem/progenitor cells by cigarette smoking renders these cells less potent in generating and maintaining normally differentiated SAE, shifting these cells towards a COPD associated phenotype. To test this, SAE basal cells will be isolated from cultured cells obtained through bronchoscopic brushings and analyzed through in vitro assays for their stem/progenitor capacities.
