Active clinical trials for "Pulmonary Emphysema"

Remote Health Monitoring (RHM) is the assessment of one's own symptoms at home between doctor visits, using things like at-home breathing tests, electronic diaries to answer questionnaires, and other monitoring devices. The hypothesis of this study is that the health and quality of life of people with COPD who do RHM for one year will be better than people with COPD who do not do RHM. Subjects who are at least 40 years old, have been diagnosed with chronic obstructive pulmonary disease (COPD), also known as chronic bronchitis or emphysema, and are current or former smokers will be invited to participate. This study is paid for by eResearch Technology (eRT). Subjects will complete 2 visits at UCLA, separated by one year of RHM. All subjects will participate in RHM. RHM will involve daily monitoring at home using a few electronic devices: blood oxygen levels, symptoms, medication use, breathing tests, and activity monitoring. Visits will include physical exam and medical history, ECG, questionnaires, breathing tests, and exercise tests.

Patients with heterogenous emphysema benefits from endoscopic lung volume reduction. Until now the technique is limited to one lobe. In case of collateral ventilation patients show no improvement. Between upper and middle lobe exists the highest collateral flow. The trial examine the hypothesis, that sequential ELVR help especially those patients, which have no benefit after lobar exclusion.

Some sparse scientific data support the hypothesis that otherwise unexplained emphysema may be associated with FLNA mutation. This prospective, monocentric, cross-sectional study aimed to describe the frequency of emphysema in patients carrying an FLNA mutation. Patients with FLNA mutations who accept the study will benefit from a chest physician's clinical examination, respiratory function tests and a chest scan. The primary endpoint is to describe emphysema's frequency in patients carrying FLNA mutation. The other objectives are to describe emphysema's features in these patients and to describe their lung function abnormalities. The final goal is to confirm the association between unexplained emphysema and FLNA mutation.

The goal of this clinical trial is to evaluate whether voice or capnometry, alone or in combination with other (non invasive) biomarkers can be used to detect emphysema on chest CT-scan in people with chronic obstructive pulmonary disease (COPD). The main question it aims to answer is: • Can a machine-learning based algorithm be developed that can classify the extent of emphysema on chest CT scan from patients with COPD, based on voice and/or capnometry. Participants will: perform different voice-related tasks perform capnometry twice (before/after exercise) perform a light exercise task between tasks ( 5-sit-to-stand test) undergo one venipuncture

The aim of this study is to test whether aspirin improves endothelial function in alpha-1 antitrypsin deficiency-associated lung disease, measured by pulmonary microvascular blood flow on magnetic resonance imaging (MRI) and with apoptotic endothelial microparticles.

The purpose of this study is to determine if the events leading to smoking-associated centrilobular and paraseptal emphysema are caused by a failure of the lungs' inherent mechanisms to block hypoxic pulmonary vasoconstriction (HPV) in areas of smoking-induced inflammation.

This study seeks to study the effectiveness of a short mindfulness based pulmonary rehabilitation program prior to a surgical resection in patients with lung cancer and severe Chronic Obstructive Lung Disease (COPD).

Improvement of sleep quality in emphysema patients is desirable. Yet, there are no data of patients treated with RePneu coils. This monocenter prospective study investigates the effect on sleep quality of RePneu coils for reduction of dynamic hyperinflation in advanced disease stages of pulmonary emphysema. Patient's sleep will be studied in three Polysomnography measurement nights, one prior to Coil Treatment, one six months after, and one twelve month after. Primary objective is to investigate differences in sleep quality 6 and 12 months after Coil Treatment. Further endpoints are changes in daily activity and sleep (actigraphy), 6MWT, lung function parameters, and questionnaires (SGRQ, mMRC dyspnoe scale).

To determine if enteral nutrition support (ENS) restores normal body weight and improves muscle strength, exercise performance, sensation of dyspnea, and quality of life in malnourished patients with chronic obstructive pulmonary disease.

The purpose of this study is evaluating the safety of endobronchial transplantation of autologous mesenchymal stem cells derived bone marrow in patients with emphysema.
