NCT ID: NCT05916495 Recruiting - Clinical trials for Lung Transplant; Complications

An Evaluation of Remote Care (Questionnaire+Hybrid) in Patients Who Are Post-lung Transplant

Start date: September 29, 2023
Phase: N/A
Study type: Interventional

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

NCT ID: NCT05836922 Not yet recruiting - Acute Kidney Injury Clinical Trials

Association Between Renal Regional Oxygen Saturation Measured by Near-InfraRed Spectroscopy and Postoperative Renal Failure After Lung Transplantation Surgery: A Pilot Study

SO-AKI-TP
Start date: July 1, 2023
Phase:
Study type: Observational

Complications after lung transplantation are almost ubiquitous, among which postoperative acute renal failure may represent more than 50% of lung transplant patients and require extrarenal purification in 5 to 13% of cases. Multiple factors are associated with postoperative acute renal failure. These factors can be classified into preoperative, intraoperative, and postoperative factors. While some postoperative complications are explained by donor and recipient factors, the literature suggests that certain intraoperative events represent modifiable or avoidable risk factors that could be targeted by therapeutic interventions to reduce the risk of postoperative acute renal failure. Some of these factors (intraoperative hemodynamic instability, significant bleeding or hypoxemia) can generate renal hypoxic aggression, alone or in combination. However, to date, there is no validated tool available at the patient's bedside during surgery to detect renal hypoxia or guide interventions to restore renal perfusion during surgery. Yet, as recent recommendations suggest, intraoperative renal protection is an important axis for improving the outcome of lung transplant patients, to the extent that the recommendations of Marczin et al. recommend the establishment of a renal prevention protocol for each patient. Without a tool to guide this plan intraoperatively, anesthesia teams can't establish a renal prevention protocol. This research aims to establish whether renal NIRS is a reliable tool for monitoring intraoperative renal hypoxic aggression predictive of postoperative renal failure. Near-infrared spectroscopy (NIRS) is an optical technology that allows non-invasive measurement of tissue oxygen saturation. This technique is commonly used for intraoperative monitoring of cerebral perfusion in adults and children. Some studies have shown that regional renal oxygen saturation (renal rSO2) measured by NIRS during aortic-coronary bypass surgery under extracorporeal circulation (ECC) is correlated with renal venous oxygen saturation measured by catheterization. It is also associated with the risk of postoperative acute renal failure in patients undergoing cardiac surgery under ECC. However, there are no equivalent data in lung transplant patients, who frequently present with postoperative acute renal failure. In the available literature, no clear threshold of renal desaturation has been established. Because it is assumed that the depth of renal desaturation can be particularly deleterious, in addition to desaturation time, the investigator have chosen to retain in this project the integral of time and magnitude spent under a renal desaturation threshold, aggregated into a renal hypoxia index, during the intraoperative period. The primary objective of this research is to demonstrate the usefulness of measuring the intraoperative renal hypoxia index in predicting the risk of early postoperative acute renal failure

NCT ID: NCT05789511 Recruiting - Gastroparesis Clinical Trials

HR-EGG in Medically Refractory Gastroparesis

Start date: December 1, 2022
Phase:
Study type: Observational

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

NCT ID: NCT05708755 Not yet recruiting - Clinical trials for Lung Transplant; Complications

CMV Immunity Monitoring in Lung Transplant Recipients

Start date: April 2024
Phase: Phase 2
Study type: Interventional

The purpose of this study is to determine the safety and feasibility of using a laboratory test to guide duration of antiviral prophylaxis with valganciclovir (medication used to prevent viral infections) after lung transplant. The laboratory test, inSIGHTâ„¢ CMV T Cell Immunity Panel, measures patients' immune response to a common viral infection known as cytomegalovirus (CMV). The goal of this study will be to safely decrease how long patients need to take valganciclovir based on the results of the CMV T Cell Immunity Panel.

NCT ID: NCT05702333 Completed - Clinical trials for Lung Transplant; Complications

Vasoactive-inotropic Support and Levosimendan Use After Lung Transplantation

VASO_LUTX
Start date: February 1, 2017
Phase:
Study type: Observational

Bilateral Lung transplantation (LUTX) is performed in selected patients with end-stage respiratory failure. During surgery, pulmonary arteries are sequentially cross-clamped. This can cause acute heart failure and hemodynamic instability that eventually persist into the postoperative period, leading to the need for prolonged vasoactive support in the postoperative Intensive Care Unit. Levosimendan is a relatively new vasoactive-inotropic drug, with different pharmacodynamic properties. This observational retrospective cohort study primarily aims 1) to describe the need for prolonged vasoactive support; 2) to evaluate the risk factors for prolonged vasoactive support; 3) to assess the impact of prolonged vasoactive support on outcomes. The secondary aim is to describe the use of Levosimendan in this cohort of patients.

NCT ID: NCT05691205 Recruiting - Clinical trials for Lung Transplant; Complications

Identifying Optimal PEEP After Lung Transplantation

PEEP-LuTX
Start date: January 31, 2023
Phase: N/A
Study type: Interventional

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

NCT ID: NCT05526950 Recruiting - Clinical trials for Lung Transplant; Complications

Cytokine Filtration in Lung Transplantation: A Swedish National Study (GLUSorb)

Start date: September 7, 2023
Phase: N/A
Study type: Interventional

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. 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 study which aims to compare patients undergoing LTx with and without the utilization of cytokine adsorption.
