Filter by:Lung transplantation (TxP) is now a validated treatment of end-stage pulmonary diseases, but long-term graft and patient survival are still hampered by the development of chronic allograft dysfunction (CLAD) affecting > 50% of patients. The investigators propose to conduct a phase III clinical randomized trial that will assess the efficacy of Nintedanib to hamper the lung decline in LTx recipients with BOS. This is the first trial testing this molecule in lung Tx recipients. If case of demonstrated effectiveness of Nintedanib, the benefit for lung transplant patients carrying a BO is high in terms of stabilization of lung function and enhancement of survival.
The goal of this study is to evaluate the utilization of conventional 'thermally' polarized perfluorinated gases mixed with oxygen as an exogenous inert contrast agent to image the airway spaces in subjects with suspected lung disease, post deployment in Iraq and Afghanistan. This is an open label proof of concept study expanding on work here at Duke.
This study aims to determine whether or not early spirometric detection and management of obstructive lung disease with combined fluticasone/azithromycin/montelukast therapy (FAM) can attenuate declining lung function, prevent the development of bronchiolitis obliterans, and improve patient outcomes following hematopoietic stem cell transplant.
A study to evaluate the role of forced oscillations in diagnosis of bronchiolitis obliterans syndrome in patients after bone marrow transplantation. The force oscillations technique will be compared with classical spirometry.
Electrical impedance tomography (EIT) is non-invasive and provides functional imaging of the lung and it could be a useful tool to diagnose chronic lung allograft dysfunction (CLAD) and specially Bronchiolitis Obliterans Syndrome (BOS). Hence, for this study, the investigators aim to show that EIT would provide an accurate diagnostic CLAD with an ability to to distinguish BOS from Restrictive Allograft Syndrome (RAS) and to stage BOS accurately when compared to FEV1 the current gold standard. The investigators are also aiming to provide physiological data in lung transplant recipients with chronic rejection.
Background: Bronchiolitis obliterans syndrome (BOS) is a complication people can experience after hematopoietic stem cell transplant. It usually affects people with chronic graft versus host disease (cGVHD). This occurs when donor stem cells attack the cells of the person who received them. BOS reduces airflow and oxygen levels in the body. It may be caused by neutrophil elastase in the body. Researchers believe the new drug alvelestat (MPH966) may help. Objectives: To test the safety of alvelestat (MPH966) and see what dose best inhibits neutrophil elastase in people with BOS after a stem cell transplant. To study how well the best dose improves lung function in those people. Eligibility: Adults 18 and older who have had a hematopoietic stem cell transplant and have cGVHD and BOS. Design: Participants will be screened with a medical history, physical exam, and blood and urine tests. They will have lung function and heart function tests. They will have computed tomography scans of the chest. Study part 1: Participants will take the starting dose of the study drug by mouth twice a day for 14 days. This is 1 cycle. They will get different doses, for up to 4 cycles. Study part 2: Participants will take the study drug twice a day by mouth at the dose set in part 1, for up to 12 months. Participants will keep medicine diaries. Participants will have several study visits. These may include: Repeats of the screening tests. Bronchoscopy with bronchoalveolar lavage. Sputum samples taken. 6-minute walking test. cGVHD assessment and answer questions. Participants will be contacted after the study for up to 24 months.
The Lung Clearance Index, measured by multiple breath washout, is a measure of lung function that is considered a research tool in Canada as the device used to measure it is not approved by Health Canada. The study will assess lung function in patients undergoing routine lung function testing for clinical indications (Cystic Fibrosis and Other Respiratory Diseases). In addition, healthy controls of different ages will be asked to perform this lung function test to gain reference data that can be used to interpret LCI in patients with lung disease.
Bronchiolitis obliterans is a chronic disease in which a persistent inflammatory process leads to obliteration of the small airways. Pulmonary function tests (body plethysmography with DLCO, lung clearance index) are performed and the fraction of exhaled nitric oxide is measured. A blood test is following to determine the inflammatory status und collect miRNA. Induced Sputum will be obtained.
Interstitial lung disease (ILD） is the late pulmonary complications after allogeneic hematopoietic stem cell transplantation (allo-HSCT) leading to high morbidity and mortality. At present, the treatment for ILD after allo-HSCT remains in discussion. In this study, the efficacy of mesenchymal stem cells (MSCs) combined azithromycin as well as glucocorticoid as the treatment of ILD will be evaluated in the recipients of allo-HSCT.
The investigators here compare lung function parameters (RV, RV/TLC and FEF75) with the results of the Lung Clearance index (LCI) . Further this study evaluates bronchial inflammatory markers in 20 patients with bronchiolitis obliterans at the age of 6 to 28 years compared with an age- and sex-matched control group. The investigators will perform a pulmonary function test (body plethysmography with DLCO) and compare the results with the LCI. Further we will measure the fraction of exhaled nitric oxide (FeNO) and draw a blood sample to determine the level of systemic inflammation. Finally induced sputum is collected and a cell count is performed, and cells and supernatants are analyzed for inflammatory markers. This study will set baseline markers for future interventional studies.
