Secondhand Smoke Respiratory Health Study
Secondhand SmokeAir Trapping4 moreExposure to secondhand tobacco smoke (SHS) is associated with diverse health effects in nonsmokers. Flight attendants (FA) who worked on commercial aircraft before the ban on tobacco smoking (exposed FAs) had high, long-term levels of occupational exposure to SHS and are a unique population for the study of long-term health effects of chronic exposure to SHS. In previous studies, we have shown that many never-smoking SHS-exposed FAs to have curvilinear flow-volume loops, decreased airflow at mid- and low-lung volumes, and static air trapping (elevated residual volume to total lung capacity ratio [RV/TLC]), abnormalities that are not diagnostic of overt Chronic Obstructive Pulmonary Disease (COPD), but do implicate the presence of an obstructive ventilatory defect, and are consistent with what has been recently described as preserved ratio impaired spirometry (PRISm). The main objective of the study is to determine the effect of a bronchodilator to counter the physiologic abnormalities that are observed in the population of never-smoking SHS-exposed FAs as both proof of concept of the presence of an obstructive lung disease and as a possible therapeutic option to counteract the adverse respiratory effects of chronic exposure to SHS.

Russian Current and Expiratory Muscle Training in COPD Patients
Chronic Obstructive Pulmonary DiseaseRespiratory muscles are essential to alveolar ventilation. In COPD, these muscles work against increased mechanical loads due to airflow limitation and geometrical changes of the thorax derived from pulmonary hyperinflation. Respiratory muscle fibers show several degrees of impairment in cellular and subcellular structures which translates, from the functional point of view, to a loss of strength (capacity to generate tension) and an increased susceptibility to failure in the face of a particular load. Expiratory Muscle Training was recommended to strengthen expiratory muscles and minimize exacerbations in addition to delaying deterioration with better functional capacity. Neuromuscular electrical stimulation (NMES) is emerging as a new rehabilitation modality for muscle strengthening that does not evoke dyspnea to obtain a benefit in patients who are unable to participate in a traditional rehabilitation program
COVID-19 Pneumonia: Pulmonary Physiology, Health-related Quality of Life and Benefit of a Rehabilitation...
Covid19 PneumoniaChronic Thromboembolic Pulmonary Hypertension2 moreThe pathophysiological processes involved in COVID-19 pneumonia are not fully understood. Specific alterations of the airways, lung parenchyma and pulmonary vascular tree could explain a severe ventilation/perfusion heterogeneity resulting in severe hypoxemia during the active phase of the disease. Additional skeletal muscle impairment related to systemic inflammation may also explain persisting symptoms in the follow-up phase. The first aim of the present project is to explore these different processes by evaluating the impact of the COVID-19 pneumonia on exercise capacity, pulmonary function and perfusion by a physiological and radiologic study. An ambulatory pulmonary rehabilitation will also be studied to assess its impact on the physiological parameter mentioned and the health-related quality of life questionnaire as a potential long-term treatment. The investigators propose a single center randomized controlled study at the University Hospitals of Geneva. 60 adult patients having suffered a hypoxemic COVID-19 pneumonia with persistent symptoms at 3-months after hospital discharge will be included. A functional and physiological study will be performed, including a six-minute walk test, pulmonary function testing, diffusing capacity for carbon monoxide, maximal inspiratory pressure and sniff nasal inspiratory pressure. Those with at least one abnormal value will be invited to fill the Saint Georges Respiratory Questionnaire, the Short Form 36 and the Hospital Anxiety and Depression Scale and will undergo a chest dual energy computed tomography (DECT), a cardiopulmonary exercise testing with non-invasive cardiac output and stroke volume evaluation and an evaluation of the pulmonary shunt by hyperoxia (100% oxygen breathing) at rest and during light effort. Then patients will be randomized on a 1:1 basis for pulmonary rehabilitation program or usual care. All work-up except DECT will be repeated at 6 and 12 months after hospital discharge. The investigators hypothesize that our study will allow a better understanding of pathophysiological mechanisms involved in COVID-19. This will potentially determine therapeutic target for patients with persisting symptoms and functional decay after COVID-19. The investigators also expect to see an improvement of exercise capacity and physiological parameters in the pulmonary rehabilitation group, as compared to the control group, suggesting pulmonary rehabilitation as a possible long-term treatment of this condition.

Pirfenidone vs. Nintedanib for Fibrotic Lung Disease After Coronavirus Disease-19 Pneumonia
Novel Coronavirus-induced Lung FibrosisThe antifibrotic agents, namely pirfenidone and nintedanib have been found to be effective in the treatment of idiopathic pulmonary fibrosis (IPF). Nintedanib has also been found to be effective in treating systemic sclerosis-related interstitial lung disease (ILD) and non-IPF progressive fibrosing ILDs. Pirfenidone has also been found beneficial unclassifiable ILDs. Whether these drugs would be effective in treating post-COVID lung fibrosis also is unknown. As the final pathway of lung fibrosis appears to be common among different diffuse parenchymal lung diseases (DPLDs), it is hoped that these antifibrotic agents might be helpful in post-COVID fibrosis. There are no randomized studies that have assessed the role of pirfenidone or nintedanib in post COVID fibrosis. In the current study, we aim to assess the efficacy and safety of pirfenidone and compare it with nintedanib in the treatment of post-COVID lung fibrosis.
