Filter by:In HIV+ cigarette smokers, with no prior history of pulmonary infections, emphysema is often developed at an earlier age and is a significant cause of morbidity despite treatment with antiretroviral drugs. Preliminary data gathered from HIV+ individuals that smoke cigarettes strongly support the hypothesis that the combination of HIV infection and smoking creates increased stress in the lower respiratory tract. To examine the underlying factors that contribute to the accelerated development of emphysema in this cohort, samples from the lower respiratory tract will be provided by HIV+ and HIV- subjects. The samples collected will serve as biomarkers for assessing the onset of emphysema.
The aim of this prospective, randomized, controlled, one-way crossover study is to assess and compare the efficacy of the Zephyr endobronchial valves vs. Standard of Care (SoC) in patients suffering from COPD with Homogeneous Emphysema. Patients will be followed up for 12 months after randomization. Patients in the SoC arm will crossover to the EBV treatment arm after the 6-month visit and will be followed up for 6 additional months.The primary objective is the variation of FEV1 between baseline and 3-month follow-up visit. The secondary objectives will evaluate quality of life, exercise capacity, dyspnea (including BODE index) changes, target lobe volume reduction, as well as safety outcomes.
To compare the clinical outcomes of Endoscopic Lung Volume Reduction (ELVR) using Pulmonx Zephyr Valves vs. Standard of Care (SoC) in the treatment of heterogeneous emphysema subjects in a controlled trial design setting.
Rationale: The combined data from 3 studies outside the Unites States investigating the Lung Volume Reduction Coil system (RePneu LVRC) showed statistically significant improvements in pulmonary function, exercise capacity and quality of life at both 6-Months and 12-Months post treatment. 24 months post treatment the improved pulmonary function and exercise capacity are slightly decreasing. Retreating the patient with the LVR coil system in other parts of the lung could potentially lead to new improvements in lung function, dyspnea, exercise capacity and quality of life and may reduce the rate of decline. Objective: To investigate the safety and feasibility of re-treating patients with severe Chronic Obstructive Pulmonary Disease (COPD) with the RePneu LVRC system.
The Prostaglandin Inhibition for Emphysema (PIE) study will determine if a currently available therapy, ibuprofen 600 mg three times daily, can block PGE production in the lower respiratory tract and if this results in improvement in measures of lung repair function.
This is a multicenter, prospective, randomized, controlled study being conducted in China to evaluate improvement of lung function after treatment with the Spiration Valve System as compared to medical management in the control group. The control group will be evaluated in the same manner as the treatment group. The Spiration Valve is a small, umbrella-shaped, one-way valve that is placed inside the airways of one lung. It is used to redirect air from the less healthy to the more healthy parts of the lung. This helps to reduce over-inflation and may improve overall lung function and quality of life for people living with emphysema.
To evaluate for any adverse effects that may be related to the administration and reception of autologous adipose derived stromal vascular fraction (SVF). Secondarily, the study monitors the results of subjective and objective findings as it applies to the non-blinded deployment of autologous SVF for various inflammatory and/or degenerative conditions including select orthopedic, neurologic, urologic and cardio-pulmonary conditions. SVF deployments include intra-venous, intra-articular, and soft tissue injections.
The combined use of one-way endobronchial valves and bone-marrow derived mesenchymal stromal cells in patients with severe pulmonary emphysema is safe and will contribute to increase quality of life.
To assess efficacy of bronchoscopic lung volume reduction in Korean emphysema patients
As part of the long-term goal of successfully implementing tissue regeneration strategies in an individualized manner for patients with thoracic diseases including, but not limited to: cystic fibrosis, pulmonary fibrosis and pulmonary hypertension, the investigators will assess the feasibility of collecting skin biopsies from patients undergoing surgery for thoracic disease, culturing skin fibroblasts from the biopsy, and reprogramming these skin fibroblasts into induced pluripotent cells.
