Autologous Bronchial Basal Cells Transplantation for Treatment of CRD Including COPD, BE and PF
Chronic respiratory diseases including chronic obstructive pulmonary disease (COPD), bronchiectasis (BE) or pulmonary fibrosis (PF) are usually not curable with damaged pulmonary structure and function. Bronchial basal cells are proved to regenerate bronchus and alveoli to repair the pulmonary injuries. In this study, we intend to perform an open, single-armed phase I clinical trial by transplantation of autologous bronchial basal cells on patients suffered from COPD, BE or PF. During the treatment, autologous bronchial basal cells, which were isolated from fiberoptic bronchoscopy and expanded in vitro, will be injected directly into...

Bacterial Gene Profiling to Predict Antibiotic Resistance During Cystic Fibrosis Pulmonary Exacerbations
Pulmonary exacerbations (PEx) are key events that lead to a decline in health status among CF patients, with many never recovering to baseline health. With the advancement of new CFTR modulators and other therapies increasing the lifespan of those living with CF, it will become increasingly important to have better strategies to manage PEx in order to have better outcomes following treatment. PEx treatment decisions will need to take into consideration the increasing frequency of antimicrobial resistance bacteria and the need to treat multiple types of bacteria at once. The purpose of this study is to analyze sputum samples from CF ...

BIO 300 Oral Suspension in Discharged COVID-19 Patients
Randomized, double-blinded, placebo-controlled, two-arm study to evaluate the effectiveness and safety of BIO 300 Oral Suspension (BIO 300) for the mitigation of impaired pulmonary function in 2019 Coronavirus Disease (COVID-19) patients recently discharged from the hospital. Patients will be randomized 1:1 to receive BIO 300 or placebo. All patients will receive the same background current standard of care.

BPF Genetics of ILD Study
The investigators aim to examine the genetic determinants of interstitial lung disease in a cohort of subjects with regular exposure to pigeons, a known cause of one form of interstitial lung disease known as hypersensitivity pneumonitis. The investigators hope the investigator's work will provide insights of use to clinicians and patients with hypersensitivity pneumonitis and other interstitial lung diseases.

Breath Condensate Study in Patients With Cystic Fibrosis.
There is an urgent need for a noninvasive method to diagnose bronchial infections and exacerbations in patients with Cystic Fibrosis (CF). The current method to diagnosed infections involves either collecting a sputum sample or obtaining a bronchoalveolar lavage (BAL). However, some patients cannot produce sputum. At the same time the decision of when a patient has an exacerbation continues to be very subjective. In this exploratory study, we propose a new, noninvasive method to diagnose bronchial infections and to evaluate possible markers of inflammation that can assist in a noninvasive way in the determination of exacerbations.

Cardiovascular Fibrosis in Idiopathic Pulmonary Fibrosis
Fibroproliferative diseases, including pulmonary, cardiac and vascular fibrosis share common pathogenetic mechanisms. Furthermore, cardiovascular comorbidities are frequently found in patients with IPF. However, the prevalence of cardiac and vascular fibrosis in patients with IPF have yet to be determined. Main Purpose of this study is to evaluate, with non-invasive methods (echocardiogram, endothelial function and pulse wave velocity) and blood biomarkers (galectins-3, osteopontin, periostin and pro-BNP), the presence of vascular fibrosis (vascular rigidity and endothelial function) and cardiac fibrosis (prevalence of HFpEF -...

CF Bronchodilation
It is estimated that one in every 3,600 children in Canada has cystic fibrosis (CF). CF is a genetic disease that affects the glands that produce mucus and sweat. In CF, mucus production increases and the mucus becomes thick and sticky. This can block the airways, making it difficult to breathe. Mucus production also causes bacteria to grow, which can lead to infections in the lungs. Individuals with CF suffer from shortness of breath, wheezing, cough, and poor exercise capacity. There are limited treatment options to reduce shortness of breath in these individuals. Some medications known as bronchodilators are commonly prescribed to...

Changes in iOS in IPF
Idiopathic pulmonary fibrosis (IPF) is a condition where scar tissue (called fibrosis) builds up in the lungs. It usually gets worse over time. Fibrosis causes the lungs to become stiff, and reduces the amount of oxygen that the lungs can take up. People with IPF complain of worsening breathlessness, which limits their day to day activities. Lung function tests are breathing tests that measure how well your lungs are working, and are used by doctors to decide whether to start or stop medicines in people with IPF. However, people with IPF tell us that lung function tests require a lot of effort, can make them cough and feel very...

Characterization of Antibacterial Antibodies in Patients With Cystic Fibrosis
Most of the cystic fibrosis (CF) patients are or have been pulmonary colonized with bacteria such as Pseudomonas aeruginosa or Staphylococcus aureus. Aim of this study is to detect virulence factor neutralizing antibodies in the sera of the study population followed by B cell repertoire analyses to design B cell-derived neutralizing monoclonal antibodies. The functionality of neutralizing antibodies rests on inhibition of virulence factors by binding of crucial epitopes rather than merely the induction of opsonization. Focusing on patients with bacterial colonization/chronic infections or a history of an acute infection in the past,...

Characterization of Apolipoprotein A-I Pathways in Idiopathic Pulmonary Fibrosis
Background: - Idiopathic pulmonary fibrosis (IPF) is a chronic lung disease that becomes worse over time. There is currently no effective treatment for it. Researchers want to study the disease and learn new ways to treat it. Objectives: - To discover new pathways that are involved in pulmonary fibrosis. To develop new drugs that may be used to treat pulmonary fibrosis. Eligibility: - People at least 18 years old with IPF. - Healthy volunteers at least 18 years old. Design: - Participants will be screened with medical history, questionnaire, and physical exam. They will...
