NCT05950724
The purpose of this study is to assess whether TNFa antibody use before lung transplant can prevent kidney injury after lung transplant.
NCT03656926
The objective of this trial was to assess the efficacy and safety of aerosolized liposomal cyclosporine A (L-CsA) as add-on therapy to standard of care (SoC) as compared to SoC alone in double lung transplant (DLT) recipients with chronic lung allograft dysfunction (CLAD)-bronchiolitis obliterans syndrome (BOS).
NCT06399302
This project aims to collect detailed clinical data, blood samples, and patient-reported outcomes from 2,600 lung transplant candidates, donors, and recipients at Lung Transplant Centers. The goal is to create a robust resource for various research objectives, including studying the impact of variations in donor and medical practices on clinical outcomes. The project also seeks to identify serum biomarkers associated with or predictive of specific post-transplant complications and conditions.
NCT07017608
Critically ill patients who (1) are not able to maintain their airway, (2) cannot breathe on their own, or (3) both, are ones who often require tracheal intubation and support from a breathing machine (mechanical ventilator). When the patient is ready to be liberated from the mechanical ventilator because the initial insult for intubation has been resolved, the patient is screened using the readiness to wean test in preparation for extubation. As the patient passes this screening, a spontaneous breathing test (SBT) is initiated. Currently, there are many debates surrounding which SBT technique is most favorable. At Toronto General Hospital, the clinical team uses a zero-end expiratory pressure (ZEEP) trial. Once the patient successfully passes their SBT they are then extubated. The patient will undergo a spontaneous breathing trial of continuous positive airway pressure (CPAP) of 5 cmH2O and ZEEP, in which time the investigators will be using a new technology called electrical impedance tomography (EIT), to study and compare the end expiratory lung volume (EELV); investigators will use an esophageal catheter to measure and monitor pressures in the lung, and also assess the patient's work of breathing. This will be repeated once the patient has been extubated safely.
NCT05691205
Lung Transplantation (LuTX) is the curative treatment for selected patients with end-stage lung disease. Primary Graft Dysfunction (PGD), a specific form of respiratory failure occurring within the first 72 hours after graft reperfusion, represents the most common complication after LuTX. Actual recommendation regarding management of mechanical ventilation of the lung graft immediately after LuTX are based only on opinion experts and not on clinical trials. Optimization of Positive End-Expiratory Pressure might contribute to both prevention and treatment of PGD. In this interventional single-center non-pharmacological study (with medical device), in the immediate postoperative period of patients who are undergone LuTX, we will evaluate the effects of varying levels of PEEP upon: - lung and chest wall mechanics, - intrapulmonary shunt fraction; - distribution of ventilation and perfusion; - gas exchange. The final aim is to find the optimal level of PEEP in this patient's cohort
NCT05916495
Lung transplantation is used to treat patients with lung damage when there is no other treatment option. Patients require close monitoring following their transplant, with hospital check-ups every 3-4 months usually lasting all day. Although check-ups often result in no change to patient management they are essential as patients have better outcomes if complications are detected quickly. The aim is to explore whether remote monitoring via an app (patientMpower) ± questionnaire (specifically designed to assess post-transplant patients' health), linked to a device to measure lung function, could replace some check-ups for lung transplant patients. Patients will be randomised to receive either normal care or remote monitoring (i.e. their symptoms will be evaluated using home spirometry combined with a questionnaire). 100 lung transplant recipients will be enrolled with 50 patients being assigned to either group. Health outcomes and costs of care between the two groups will be compared
NCT05376605
This study was aimed to evaluate the patients undergoing lung transplantation under the International Classification of Functionality, Disability and Health (ICF) and to examine the relationships between the age at which lung transplant recipients were transplanted and recipients' comorbidity levels and body structure and functions, activity and participation level.
NCT03126968
Bleeding poses potential for significant complication after transbronchial lung biopsies. The investigators hypothesize that prophylactic intrabronchial instillation of topical epinephrine will reduce the likelihood of bleeding. The investigators plan a double-blind, placebo controlled trial to evaluate this hypothesis.
NCT05081141
Solid organ transplant candidates will undergo serological screening for HHV8 at time of listing and transplantation. In the event of a recipient/donor mismatch R-/D+ or in the presence of a seropositive recipient (R+), blood levels of HHV8 DNA will be monitored together with specific IGRA for HHV8.
NCT05116748
Background: ISHLT and AASLD guidelines recommend SARS-CoV2 vaccination in all individuals undergoing lung and liver transplantation, but there are currently scarce data on the safety and efficacy of these vaccines in this population. In Italy, immunocompromised patients have received the indication to be administered mRNA vaccines only. Primary outcome: safety and reactogenicity Secondary outcomes: immunogenicity and prevention of COVID19 Visits and timepoints: * T0: before first dose administration: visit and venous sampling to assess baseline COVID19 serum status * Telephone calls to assess safety and reactogenicity 1 and 2 days after each dose of vaccination * T21 or 28 (based on vaccine; mRNA BNT162b2 and mRNA-1273, respectively): visit, venous sampling to assess immunogenicity * Follow up visits after 60, 120, 180 and 365 from T0: visit and venous sampling to assess immunogenicity
NCT05242289
Lung transplantation (LTx) remains the gold standard for treating patients with irreversible end-stage pulmonary disease. Of the major organs transplanted, survival in LTx recipients remains the lowest (mean 5 years). Despite improvements, primary graft dysfunction (PGD), as defined by respiratory insufficiency and edema up to 72 hours post LTx, remains the leading cause of early mortality and contributes to the development of chronic lung allograft dysfunction (CLAD) which is the leading cause of late mortality (2). PGD develops within the first 72 hours after LTx. The development of CLAD increases quickly with cumulative incidence of 40-80 % within the first 3-5 years. There is a general lack of efficient treatments for PGD and CLAD. Prevention of PGD is therefore of crucial importance and has a direct impact on survival. The present study is a randomized controlled pilot study which aims to compare patients undergoing LTx with and without the utilization of cytokine adsorption.
NCT04505878
This study is being done to determine if parenterally administered ascorbic acid (Vitamin C) given at the time of lung transplant is safe. Vitamin C may be an effective intervention towards primary graft dysfunction (PGD). The study will enroll 69 participants who consent to the intervention. Participants who do not consent to the intervention will be treated according to standard-of-care, but may choose to be consented to have their data retrospectively reviewed. Based on our consent rate, this group may include 40-70 participants. Participants will be on study for up to 12 months.
NCT03562416
The aim of this study is to assess the utility of nintedanib therapy in addition to usual transplant care in single lung transplant recipients with idiopathic pulmonary fibrosis (IPF). The investigators hypothesize that in IPF subjects who undergo single lung transplantation the administration of nintedanib 150 mg twice daily in addition to usual transplant care will result in better preservation of lung function at 24 months.
NCT05789511
The goal of this observational study is to utilize a novel high resolution electrogastrography device to gauge if identification of gastric dysarrythmias can reliably identify patients that will respond to or will require definitive pyloric interventions such as a G-POEM procedure in patients with medically refractory gastroparesis Aims: 1. Assess for the presence of gastric dysarrythmias in lung transplantation population as compared to alternative etiologies of gastroparesis 2. Assess if presence or absence of gastric dysarrythmias is predictive of response or need of Gastric -per-oral endoscopic myotomy 3. Assess alterations in gastric dysarrthmias following pyloric interventions including G-POEM. Patients will undergo two surface body surface gastric mapping via the HR-EGG before and after undergoing a gastric per oral endoscopic myotomy as standard clinical care for the treatment of medically refractory gastroparesis
NCT03221764
This study will prospectively evaluate the use of an amiodarone releasing hydrogel applied to the pulmonary veins and atria at the time of lung transplantation. This study will include patients undergoing lung transplantation at Jewish Hospital, Louisville KY. The prospective group will be compared to historical controls from the same institution. Investigators will access medical records and database entries for those patients undergoing lung transplantation after January 1st 2005 in order to obtain matched controls for analysis. Informed consent will be obtained from the prospective cohort prior to patient enrollment. This pilot study will be used to obtain preliminary data in order to proceed with a larger randomized control trial.
NCT03368365
Acute cellular and/or humoral rejection and early graft infections after pulmonary transplant (\<2.5 years) are common and can lead to chronic dysfunction of the transplanted organ or Chronic Lung Allograft Dysfunction, CLAD. These complications increase the number of unplanned and life-threatening hospitalizations. Regular multi-weekly monitoring of respiratory function is necessary to detect these complications early and to make their management more effective and less costly. Monitoring by micro spirometers with forced expirations at home proved difficult to perform (patient and effort dependent), often poorly coordinated (transmission of data to practitioners) and not sensitive in the prediction of post-transplant complications. Aqsitania has developed an innovative analysis of resting respiratory signals. This innovative analysis is called "Anharmonic Morphological Analysis of Respiratory Signals (AMARS)". This automated analysis is based on a measurement of the respiration collected by a spirometry device communicating and allowing a remote home monitoring (Ventilotel®). We hypothesize that this Anharmonic Morphological Analysis of Respiratory Signals at rest could predict unplanned hospitalizations and allow for more reliable monitoring of pulmonary transplant patients. Inclusion visit: Explanation of the study and collection of consent, measurement of resting breath and explanation on the mode of use of the measuring device at home, clinical examination, respiratory functional exploration. Follow-up at home for 12 months with a resting breath measurement for 2 to 3 min, in the morning on waking and in the evening before bed, 2 days / week with automatic sending of data on the Aqsitania server. The first month, a visit at home can be made if the subject feels the need. At each measurement, Aqsitania transmits the data in the e-CRF, a report that gives the anonymised values of the markers and the current personal respiratory profile. In order to avoid "motivational" bias, patients will have instructions to use the device but no "coaching" call will be made during the study. Patients will have their monthly or quarterly follow-up visits, including clinical examination, respiratory functional exploration and an analysis of adverse events. No additional search-specific visits will be carried out.
NCT03276403
The validity of several functional parameters, which could be included in a new PGD scoring system, will be tested in a prospective pilot study of 80 consecutive bilateral lung transplant recipients in high volume lung transplant centers. Functional parameters will be collected at different time points within the first 72hrs after lung transplantation and their accuracy in predicting clinical outcome as well as their correlation with lung water content (measured by PiCCO) will be tested. Insights will serve to generate a hypothesis (a novel PGD score), which can then be tested in future prospective trials.
