Filter by:The goal of this observational study is to develop and validate a molecular heart rejection diagnostic system based on targeted transcriptome as a novel monitoring companion tool for heart allograft precision diagnostics applicable to formalin-fixed paraffin-embedded endomyocardial biopsies. The primary outcome will be the biopsy-proven rejection, that will be predicted with molecular classifiers (cellular and antibody-mediated rejection scores).
The objective of this prospective observational single center study is to investigate donor-derived cell-free DNA (ddcfDNA), peripheral blood platelet mRNA, peripheral blood extracellular vesicle mRNA, and peripheral blood leukocyte mRNA expression in recognition of clinically significant endomyocardial biopsy (EMB) proven acute rejection in human heart transplant recipients. In detail, the objective is to develop novel biomarkers and liquid biopsies for diagnosis, prognosis, and targeted molecular therapy for primary graft failure, ischemia-reperfusion injury, acute rejection, and development of late graft failure and cardiac allograft vasculopathy, and for monitoring immunosuppression after heart transplantation.
Patient who received a heart transplant may develop organ rejection. Currently, an invasive biopsy of the heart needs to be performed to diagnose rejection. The purpose of this research study is to identify novel metabolic biomarkers that can be developed into a blood test that can identify signs of rejection without doing a heart biopsy.
We will conduct a two-group randomized controlled trial to examine the eMocha DOT intervention with pediatric HT recipients.In this population, medication nonadherence remains a primary cause of late acute rejection (LAR) episodes, increased number of hospitalizations, graft failure, and patient mortality. Herein, we propose an innovative approach to promote medication adherence and improve patient and graft outcomes.
The ProTECT registry is an observational longitudinal, multi-center study observing patients undergoing heart transplant for whom Prospera testing is part of routine clinical care, who are enrolled within 60 days of heart transplantation.
Cross-sectional evaluation of antibody mediated injury in heart transplantation patients through a multimodal approach: electron microscopy, optic microscopy, immunohistochemistry techniques, transthoracic echocardiography, cardiac magnetic resonance, pressure guide wire, intravascular ultrasound
This prospective, multicenter, non-interventional trial aims to study the association between TTV viral load and the occurrence of rejection or infection during the first year after transplantation. The TTV viral loads, taken once a month during the first year after the transplant, will be measured at the end of the study.
FreeDNA-CAR is a prospective, observational multicenter study, that will include a total of 200 adult heart transplant (HT) patients from 14 centers in Spain. Our main objective is to test donor-derived Cell-Free DNA (dd-cfDNA) against endomyocardial biopsy (EMB) for the diagnosis of acute cellular rejection.
This trial was a single-center, prospective cohort study.The purpose of this clinical research is to evaluate the accuracy of combining multimodality MR Imaging with circulating exosomal miRNA expression to diagnose acute rejection in patients with heart transplantation，thus it may be helpful for timely intervention to improve the patient's prognosis.
Demonstrate the relationship between DD-cfDNA levels and HLA antibodies in blood transplant recipient and the Molecular Microscope® (MMDx) Diagnostic System results in indication and protocol biopsies from heart transplants.
