After InterVapor treatment, patients will be followed for 5 years as per the standard of care and safety and efficacy data (quality of life, pulmonary function, exercise capacity) collected as part of the registry.
Biological Investigation of Explanted Endobronchial Lung Valves Study
Emphysema or COPDRationale: COPD is a severe, often progressive and currently incurable lung disease which affects both the upper airways (chronic bronchitis) as well as the lower airways (emphysema). In advanced stages of the disease air-trapping severely reduces the ability to breathe and subsequently the quality of life. A highly effective treatment for restoring lung mechanical functionality of these patients is the introduction of bronchoscopic lung volume reduction (BLVR), e.g. implanting small silicone/nitinol valves (EBV) inside the airways to reduce air-trapping. Although successfully investigated in a selected group of severe COPD patients, the effectiveness of the treatment can sometimes be short-lived due to fibrotic and granulation responses and tissue-material interactions. Objective: The main objective of this study is to study and understand the underlying biological principles of granulation and fibrotic responses limiting the effectiveness and longevity of BELVR treatment with EBVs, this to investigate the mechanism of action of tissue-device interactions.
Kingston Chronic Obstructive Pulmonary Disease (COPD) Multidimensional Long Term Follow up Cohort...
COPDEmphysemaBackground: Chronic Obstructive Pulmonary (COPD) patients are the paradigm of the chronic complex patient. Their follow up can sometimes be difficult and challenging (1). There are patients with recurrent exacerbations that put an enormous burden on health care resources (2). They also have multiple comorbidities (3) that can sometimes make their management difficult. In an attempt to coordinate all these efforts KGH, HDH and Providence Care have numerous essential resources to take care of COPD patients like the nurse navigators, nurse practitioners and the pulmonary rehabilitation program. These programs provide an excellent support to the clinical activity of Respirologists and other health care providers. Rationale: The main rationale for the development of the Kingston COPD cohort is to translate that highly demanding clinical activity in a teaching and research oriented activity that could be used by clinicians, medical students, residents and fellows. Having a guideline complained established protocol in COPD patients that are usually follow at KGH and HDH could help in not only in unified the way COPD patients are seeing (preserving the importance of the personalized approach) but most importantly established a multidimensional (clinical, physiological, radiological, laboratory) database. This could help know not only the results of our clinical activity but also have a long term (>5yrs) database for clinical research projects in collaboration with national and international research groups. Therefore this proposal is important because it will help translate our busy daily clinical work in a highly productive teaching and research activity.
Functional Lung Imaging in Patients With Respiratory Compromise Undergoing Endobronchial Valve Placement...
EmphysemaBronchoscopic lung volume reduction (BLVR) using endobronchial valves is effective in improving quality of life in patients suffering from emphysema. BLVR treatment in advanced emphysema requires targeted segmental or sub-segmental placement of endobronchial valves (EBV) to achieve total lobar occlusion to induce effective lobar volume reduction. BLVR procedure success rate declines in patients with incomplete lobar fissure integrity due to the potential for collateral ventilation to circumvent EBV lobar occlusion. Current methods that assess lobar collateral ventilation as a correlate of fissure integrity are imperfect, resulting in a significant percentage of patients having equivocal assessment, leading to suboptimal selection of patients and potential for inappropriate selection of patients for BLVR. Additionally, methods used to select the target lobe for EBV placement predominately rely on the extent of emphysematous destruction. There is also a need to select based on the extent of physiological disturbance at the lobar level. Distribution of ventilation or regional ventilation heterogeneity may be associated with collateral ventilation. Therefore, in this study we wish to quantify lobar distribution of ventilation and ventilation heterogeneity in patients undergoing investigation for BLVR to determine the additive contribution of functional lung imaging for assessing lobar physiological derangement and suitability for EBV treatment.
Characterizing Matrix Metalloproteinase-12 (MMP12) in Sputum
EmphysemaThe hypothesis is that in patients with emphysema, a high MMP12 sputum and/or blood level correlates with airspace enlargement and with increased sputum Th2 immune biomarkers.
The Lung Microbiome and Endobronchial Valve Treatment
Chronic Obstructive Pulmonary DiseaseEmphysemaLung emphysema is often associated with chronic obstructive pulmonary disease (COPD) and without any cure. Dyspnea is the main, debilitating symptom and is relieved by inhaled bronchodilators and rehabilitation. However, a substantial number of patients continue to suffer from dyspnea and among these, many patients have severely hyperinflated lungs due to predominant emphysema. For selected patients, lung transplantation or lung volume reduction by surgical removal (LVRS) of the most emphysematous parts of the lung can improve symptoms and survival. However, LVRS is related to complications and not all patients are suitable for surgery. An alternative to LVRS is bronchial lung volume reduction with endobronchial valves (EBV). One-way valves are inserted in the bronchial system using a bronchoscope and it has emerged as a valid treatment option with similar effects as LVRS with reduction of hyperinflation and increasing pulmonary function, quality of life, and exercise capacity. The normal lung is colonized with several types of bacteria, and together this is called the microbiome. Some bacteria are potentially beneficial, while others are potentially harmful. After the insertion EBV, some patients develop chronic infections. The hypothesis is that the microbiome can affect the risk of this chronic infection, and therefore the objective of this study is to access the microbiome during the insertion of the EBV, and afterwards observe which patients develop chronic infection and if these patients are harbouring specific types of bacteria.
Emphysema Research Registry and Biosample Repository
EmphysemaChronic Obstructive Pulmonary Disease1 moreThe Comprehensive Lung Center (CLC) at the University of Pittsburgh Medical Center (UPMC Health System) provides patients with any type of breathing or lung disorder a full range of diagnostic and therapeutic services. The Emphysema/COPD Research Center (ECRC) is a specialty clinic, within this center, that attempts to advance the understanding of emphysema and to evaluate new therapies for patients with emphysema. The Emphysema Research Registry will enable pulmonary research physicians to: 1) gather information and create a research registry of people who have been diagnosed with emphysema; 2) utilize this research registry with the purpose of conducting research that attempts to advance the understanding of emphysema and to evaluate new therapies; and, 3) use the research registry to identify potential candidates for future research programs. These aims will be achieved by the collection of DNA (genetic material)for analysis and storage in addition to pulmonary function tests and other medical information.

Bronchoscopic EmphysemA Treatment in THE NetherLands
COPDRationale: New bronchoscopic treatments for emphysema have shown promise in clinical trials, improving lung function, exercise capacity and possibly survival and are now being adopted by a number of centres in the Netherlands. It is important to ensure that the benefits seen in clinical trials are in fact reflected in clinical practice and that the best use of this early 'real world' experience is made to optimise the development and use of these novel therapies. Overall objective: to develop a national database to record bronchoscopic lung volume reduction procedures for patients with emphysema. This is desirable for audit purposes but will also be an important resource for research both in gathering data and in facilitating collaborations.
