Filter by:The purpose of this study is to evaluate the efficacy of ARALAST NP A1PI augmentation therapy 120 milligrams per kilogram (mg/kg) body weight (BW)/week compared with an external placebo comparator on the loss of emphysematous lung tissue measured by lung density change in participants with A1PI deficiency and COPD-E.
Pneumonia is a recurrent element of COVID-19 infection, it is often associated with development of respiratory failure and patients frequently need various degrees of oxygen therapy up to non invasive ventilation (NIV-CPAP) and invasive mechanical ventilation (IMV). Main purpose of this study is to evaluate with non invasive clinical instruments (pletysmography, Diffusion lung capacity for carbon monoxide -DLCO-, six minute walking test and dyspnea scores) and radiological tools (chest X-ray and chest CT scan) the development of medium-to-long term pulmonary sequelae caused by SARS-CoV-2 pneumonia.
The data of patients undergoing bronchoscopic volume reduction procedure will be analyzed retrospectively. Patients will be divided into two groups as patients with and without Pulmonary Rehabilitation before the procedure, and changes in functional levels of patients will be compared.
This is a single-arm, prospective, multi-center, Registry study to evaluate the long-term safety and effectiveness of the Spiration Valve System (SVS) for the treatment of severe emphysema in a post-market setting.
Rationale: A big step forward and great opportunity to improve overall efficacy of bronchoscopic lung volume reductioen is to combine treatment modalities aiming to close the dependent collateral channels and then proceed with EBV therapy to induce lobar collapse, and thus maximal treatment effect. Objective: Primary objective: 1. To investigate the feasibility of injecting AeriSeal into the interlobar collateral ventilation channels region to make the target lobe suitable for endobronchial valve treatment. Secondary objectives: 2. To investigate the safety of injecting AeriSeal into the interlobar collateral ventilation channels region to make the target lobe suitable for endobronchial valve treatment. 3. To investigate the effectiveness of injecting AeriSeal into the interlobar collateral ventilation channels region to make the target lobe suitable for endobronchial valve treatment.
Rationale: 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.
Background: 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.
The purpose of this Post-Approval Registry is to gather ongoing safety and effectiveness assessment of the Zephyr Valve treatment in a real-world setting.
This is a Post-Market Evaluation of the Zephyr Valve 5.5-LP EBV to assess Treated Lobar Volume Reduction (TLVR), changes in lung function and the safety profile of the Zephyr Valve treatment with the use of at least one Zephyr Valve 5.5-LP EBV.
Rationale: The bronchoscopic lung volume reduction treatment using vapor was found to be effective and the treatment has an acceptable safety profile. The results of this trial has led to the inclusion of this treatment in the COPD GOLD guidelines in 2019. In the Netherlands the treatment has not been performed so far but the treatment device has been made available to the UMCG hospital to perform emphysema treatments. Some of the patients refered to the UMCG could benefit from the Vapor treatment and therefore with this treatment we will be able to treat patients who have no other treatment options left. Objective: The overall aim of this study is to gain experience with the Thermal Vapor treatment by investigating the safety and efficacy of the treatment. Primary Objective: The primary objective is to investigate the change in Lung function (measured by Forced Expiratory Volume in 1 second (FEV1)) between baseline and 6 months after the Thermal Vapor treatment. Study designThis study will be a prospective observational, single center study. All patients that undergo the bronchoscopic lung volume reduction treatment using thermal Vapor will be asked if their data can be captured in the database. Study population: Patients with severe COPD who undergo the Thermal Vapor treatment.
