Active clinical trials for "Emphysema"

To investigate coronary heart disease and stroke among American men of Japanese ancestry who were living on the island of Oahu in 1965. Morbidity and mortality surveillance of the original cohort is continuing.

CT studies considering bronchial dimensions in chronic obstructive pulmonary disease (COPD) were conducted without control of bronchodilation. Some data however suggest that total lung capacity (CT scan is performed after full inspiration) is increased in individuals affected by chronic or spontaneous bronchoconstriction and may decrease after bronchodilatation. Furthermore, no study has assessed the effect of bronchodilation on CT scans parameters reflecting airway remodelling and emphysema extent in COPD patients. This is a prospective study whose purpose is to assess the effect of bronchodilation on lung CT scan and pulmonary function testing (PFT) in COPD patients.

The purpose of this protocol is to obtain biologic materials from the blood and lungs from patients with lung disease in order to develop an understanding of the etiology and pathogenesis of these disorders. General admission criteria for this project will require at least one of the following: (1) symptoms consistent with pulmonary disease; (2) chest X-ray consistent with lung disease; (3) pulmonary function tests consistent with lung disease; (4) lung biopsy consistent with lung disease; (5) family history of lung disease; and (6) patients with diseases of organs with known association with lung disease.

The aim of this study is to investigate the mechanisms whereby leukocytes are recruited to the lung in chronic obstructive pulmonary disease (COPD) and cause tissue destruction. The hypothesis is that in COPD more leukocytes enter the lung and it is these cells that are responsible for the degradation of lung tissue. We, the researchers at Imperial College London, will isolate leukocytes from the blood of patients with COPD, healthy smokers and normal subjects and measure the movement of the leukocytes to chemoattractants. We will examine further, which cell surface receptors are responsible for this trafficking of cells. Furthermore, the differentiation of these cells in vitro will be compared with cells from healthy smokers and normal subjects. Specifically, the expression of enzymes that are responsible for tissue destruction and the cell surface receptors on these cells will be investigated. The objective is to identify the mechanisms whereby leukocytes from COPD patients behave differently to cells from healthy smokers and normal subjects with a view to identify novel targets for drug therapy.

The objective of this post-marketing study is to advance the understanding of the mechanism of action of the CE marked RePneu Coil by observing changes in lung physiology and cardiac performance in patients with emphysema treated with the RePneu Coils, when used as intended.

This is an observational study examining outcomes and treatment patterns in a community-based cohort of subjects with Chronic obstructive pulmonary disease (COPD) who are based in the Kannapolis, NC area.

Chronic heart failure (CHF), chronic obstructive pulmonary disease (COPD), and interstitial lung disease (i.e., pulmonary fibrosis) are common serious illnesses. Despite disease-specific medical care, people with these illnesses often left with poor quality of life (i.e., burdensome symptoms, impaired function). Furthermore, while these illnesses are leading causes of hospitalization and mortality, few people with these illnesses engage in advance care planning, the process of considering and communicating healthcare values and goals. The investigators are conducting a randomized clinical trial to study a symptom management, psychosocial care and advance care planning intervention to improve quality of life. The study is important because it aims to improve quality of life and provision of care according to peoples' goals and preferences in common, burdensome illnesses. Furthermore, this study will generate information that supports the broader dissemination and implementation of the intervention and informs the development of future palliative care and team-based interventions in the VA.

The goal of the small feasibility trial is to establish a method, material, and patient-specific design that is superior to what is in use today. The first round of patients are well known to the physician investigator and are familiar with the problem that is being resolved. The end goal of the project is to create a new patient-specific design that will last longer, fit better, and cause less trauma to the airway and the patient.

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.

The purpose of this study is to create a patient registry to collect and analyze information on subjects treated with the CryoSpray Ablation™ System post-510K approval.
