Filter by:The goal of this observational study is to explore the different immunosuppressive agents and related outcomes in organ transplantation patients in Taiwan. The main question it aims to answer is the risk of different immunosuppressive agents for infection and survival after transplant. The study enrolled patients who underwent solid organ transplant (SOT), kidney (ICD-9-CM code V42.0), liver (ICD-9-CM code V42.7), or lung (ICD-9-CM code V42.6) transplants. We employed propensity score matching (PSM) to establish a matched cohort. The study will compare SOT patients and general patients to explore the risk of different immunosuppressive agents for infection and survival.
Despite the greater risk of adverse COVID-19 outcomes, antibody and cell-mediated immune responses to COVID-19 vaccines vary amongst immunocompromised (IC) people and are poorly defined. IC hosts were largely excluded from the COVID-19 vaccine registration trials, though many countries recommend additional and booster doses of vaccination in this group. BOOST-IC is an adaptive randomised clinical trial (RCT) to assess the immunogenicity and safety of additional COVID-19 vaccine doses in immunocompromised (IC) people, including people with HIV, solid organ transplants (SOT) recipients or those with haematological malignancies. Briefly, the study aims to generate high-quality evidence on the immunogenicity and safety of alternative COVID-19 booster strategies against SARS-CoV-2 for IC people in Australia.
This study aims to constitute a collection of biological materials from in transplant patients and to provide biological materials from transplanted patients in order : i) validate new theory on the cause of allograft loss, ii) develop innovative biomarker for rejection and other transplantation-related conditions (such as BK virus nephropathy, Post-transplant lymphoproliferative disorder ( PTLD) ...)
Increased indications for transplantation continue to worsen the shortage of organs and need the extension of graft sampling criteria and the search for new potential sources of organs. Despite undeniable success in the short term, due to major advances in surgery, medicine and research, transplant recipients continue to face the risk of chronic rejection and long-term complications. The University Hospital Federation "FHU SUPORT" was created to optimize the chances of success of the organ transplant and improve the quality of life of the transplanted patient. FHU SUPORT 's ambition is based on a translational strategy that presents two priority areas: Axis 1: Optimization, evaluation, conditioning of the donor, graft, recipient Axis 2: Personalized follow-up of the transplanted patient in the short and long term Identifying factors for long-term graft and patient survival through translational research from a common cohort and biological collection will predict transplant rejection, prolong graft function, or improve the patient's care.
An immunomodulatory protocol, experimentally-proven to promote T-regulatory dependent graft protective mechanisms was applied in a clinical cohort of 13 intestinal transplant recipients to activate - in a protolerogenic environment - T-regulatory cells. This protocol is the standard of care in the investigators intestinal transplant programme since the first intestinal transplant was performed in october 2000.
The purpose of this study to develop a well-characterized library of blood, biopsy tissue, and urine samples from transplant patients. Subjects without transplants will also be enrolled for comparison. Samples will be used to study the characteristics of patients undergoing transplantation that influence their response to transplant therapies and their reactions to drugs used in transplantation. This knowledge is important as it helps physicians design new drugs and tailor transplant therapies to the individual thereby reducing the side effects. In this study, people will be asked to donate blood, biopsy tissue and urine. Donation of these samples will not influence patients' treatments. These samples will be tested using a variety of biological tests to better understand how immunosuppressive drugs change the various components of the immune system. The tests will be for research only; no changes in an individual's treatment will be based on the results of tests performed in this study. If there is extra sample, the sample will be stored for use in other testing at a later date. The ultimate goal is find the right combination of medications for each individual patient while keeping their new organ working well. This study is a first step in that direction by perfecting tests used to characterize a patient's immune system
Organ transplant patients who participated in a retrospective study and received 2009 Pandemrix vaccine during autumn 2009 are included in this study. The main aim is to determine the H1N1 antibody levels one year after Pandemrix in comparison to healthy controls. The secondary aim is to examine the booster effect of 2010 Fluarix in patients and controls.Side effects to Fluarix vaccine are registered.
The purpose of this study is to investigate the pharmacokinetics of rectal and sublingual administration of tacrolimus and to compare with pharmacokinetics after oral administration of tacrolimus in renal transplant patients before transplantation.
A systematic evaluation of predictors of health related quality of life (HRQoL) leads to multiple level of data analysis. The aim of the herein described observational project is to create a transplant patients registry on psychosocial outcomes and to evaluate longitudinally predictors of HRQoL after different types of solid organ transplantation in the long-term. A sample size of 700 participants consisting of all solid organ types is envisioned. Data will be compared with published healthy normative data. Data Evaluation of predictors of HRQoL may guide development of tailored interventions to reduce complications and to further improve outcomes.
The purpose of the study is to assess the gastrointestinal tolerability of EC-MPS compared to MMF in maintenance transplant patients on a calcineurin inhibitor regimen, who require MMF dose reductions of 25% or more due to GI complications. The tested hypothesis is that the EC-MPS treatment is superior to the MMF therapy in terms of tolerability and that patients on the EC-MPS formulation will be able to tolerate higher doses compared to those on MMF.
