Filter by:This randomized, feasibility trial (n=40) will compare the effects of an intensive, twice daily inpatient physical rehabilitation program against standard care (once daily) following double lung transplantation.
This study will evaluate the maximum safe dose and duration of regadenoson (Lexiscan) that can be given to people who are having a lung transplant. Regadenoson will be given as a continuous IV infusion. All participants in the study will receive a regadenoson infusion beginning in the operating room during the lung transplant procedure. Participants will be assigned a certain dose of regadenoson to be given over a 12 or 24 hour period.
The goal of this research is to optimize the MRI system to obtain ideal lung images using Hyperpolarized (HP) Noble and Inert Fluorinated Gases as contrast agents. Lung coils tuned to the frequencies of these gases will be used. This study will take place at TBRHSC in the Cardiorespiratory Department and in the Research MRI facility.
While many patients experience benefits from transplant, complications such as infections and lung rejection may affect long term survival and quality of life. In this study doctors are looking at a complication called Chronic Lung Allograft Dysfunction (CLAD). CLAD is thought to be chronic rejection of the lung by the immune system and is the leading cause of death after lung transplantation. The purpose of this study is to help doctors determine: - why some people get CLAD and others do not - how patients who get CLAD do after CLAD is diagnosed - how CLAD may affect quality of life
In this study, doctors are trying to see if a study drug called rituximab (Rituxan®) will lower the number of B cells in the body. Doctors are also trying to see if decreasing B cells with rituximab (Rituxan®) can prevent injury to the transplanted lung. This treatment has been studied in other types of solid organ transplants.
The overall objective of this study is to evaluate the clinical effectiveness of the novel technique of donor EVLP in increasing lung transplant activity by allowing previously unusable donor lungs to be safely used in clinical lung transplantation. Furthermore, to utilize the EVLP technique in research settings thus allowing the evaluation of inflammatory molecules (biomarkers) that would benefit a successful pre-conditioning and increase knowledge of the lungs inflammatory response before transplantation.
To evaluate the safety and effectiveness of the OCS™ Lung to recruit, preserve and assess donor lungs that may not meet current standard donor lung acceptance criteria for transplantation.
Open multicentric prospective study performed on pulmonary transplanted patients to detect the values of different diagnostic markers for immuno- humoral reaction and their roles in the humoral rejection for those patients.
Human donor lungs that do not meet the standard clinical criteria for donor lung utilization but fit into the study inclusion criteria will be retrieved from the donor using current donor lung retrieval techniques.
Lung transplantation is indicated when end-stage lung diseases no longer respond to available standard therapy, making life expectancy short and associated with disability. Acute and chronic rejection are common complications following transplantation, indicating screening bronchoscopies and transbronchial biopsies at three month intervals the first two years, in addition to clinically indicated procedures when rejection or infection is suspected. Transbronchial biopsies carry associated risks (bleeding, pneumothorax). Chronic rejection is characterized by progressive obliteration of distal airways (Bronchiolitis Obliterans-BO-). BO requires open lung biopsy for diagnosis. Alternatively, a clinical surrogate (Bronchiolitis Obliterans Syndrome), characterized by decline in Forced Expired Volume in 1 second not explained by acute rejection or infection is used for diagnosis. The new technique of confocal endo-microscopy enables sub-surface visualization of tissue in vivo during bronchoscopic procedures using a probe-based confocal microscope, integrated to a standard endoscope. Bronchiolar and alveolar structures can be visualized at a cellular and nuclear level, and these images can be saved and reviewed. This new technology could potentially identify acute and chronic rejection, thus offering and alternative to transbronchial biopsies. We expect to describe a new alternative to diagnose acute and chronic rejection using confocal microscopy images obtained endoscopically, obviating complications of transbronchial biopsies. Endoscopic confocal endomicroscopy can detect and classify common bronchiolar and alveolar pathological conditions in real time. Specifically, we hypothesize that confocal endomicroscopy images of bronchiolar and alveolar structures during standard bronchoscopy could help to recognize and classify the presence/absence of acute rejection and/or bronchiolitis obliterans syndrome in lung transplant recipients. This technology could also identify the histological characteristics lung diseases such as interstitial, obstructive or vascular end stage lung diseases, and thus lead to more efficient, safer and more accurate diagnosis of these lung conditions during routine bronchoscopies.
