Filter by:The objective of this study is to determine whether cell-free DNA (cf-DNA) measurement can be used as a biomarker for successful treatment of an acute rejection (AR) episode after kidney transplantation. A fall in donor cf-DNA level may be a biomarker for successful AR treatment. The goal is to do an exploratory study to determine, in recipients with biopsy-proven AR, whether persistence or elevated levels of donor cf-DNA are associated with ongoing inflammation at the time of exit biopsy; and whether fall in donor cf-DNA level is associated with successful AR treatment. Measurement of cf-DNA has recently been started for kidney transplant recipients. There will be two groups of patients eligible for this study: 1. those who have had sequential measurement of cf-DNA prior to graft dysfunction leading to a biopsy, and 2. those who have not had previous measurement of cf-DNA
The success of transplantation is significantly hindered by the lack of sufficient number of available donors. Many potential donor organs cannot be utilized in clinical transplantation because donors have chronic viral infections such as hepatitis C (HCV) infection. This study will test the possibility of safely transplanting organs from HCV-infected donors into HCV-uninfected recipients. Prior to transplantation, recipients will receive an initial dose of highly effective antiviral prophylaxis using approved direct-acting antivirals (DAAs) Glecaprevir/Pibrentasvir (G/P) and they will also receive ezetimibe, a cholesterol-lowering medication that also blocks entry of HCV into liver cells. They will then receive daily dosing of the same medications for 7 days after transplant. The aim of the study is to show that transplantation of organs from HCV+ donors is safe in the era of DAAs. The investigators hypothesize that rates of HCV transmission to recipients will be prevented by the use of DAA prophylaxis and any HCV transmission that does occur will be readily treatable and curable. If successful, the knowledge from this study can have a large impact to patients with end stage organ diseases by providing a large novel source of donors for organ transplantations.
The primary aim of this trial is to assess the feasibility of a novel online weight gain prevention resource for new kidney transplant recipients at two London transplant clinics. A previous study conducted by the research team titled 'ExeRTiOn' provided usability feedback that led to revisions of this online resource in a purposive sample of kidney transplant recipients (n=11) and transplant multidisciplinary team members (n=6).
This trial evaluates the addition of rituximab to standard of care in the treatment of antibody-mediated rejection in kidney transplant patients. The trial will involve adults and children. Half of participants will receive standard of care (methylprednisolone, intravenous immunoglobulin and plasma exchange), while the other half will receive standard of care and rituximab.
This study will assess the immune responses to the recombinant, AS01-adjuvanted varicella zoster virus subunit (HZ/su) vaccine or SHINGRIX in immunosuppressed patients, particularly those who have received a renal transplant, and aim to better understand if the vaccine and perhaps other adjuvanted vaccines are safe in these patients. 30 participants will be divided into 2 groups, one group will receive the 1st out of 2 doses of the vaccine 3-6 months after transplant per standard of care and the second group will receive the 1st out of 2 doses of the vaccine 12-36 months after the transplant per standard of care.The duration of the study is 180 days.
The purpose of this study is to compare once-daily tacrolimus extended-release (Envarsus XR®) to twice-daily immediate release tacrolimus to find out if people taking tacrolimus extended release (Envarsus XR®) report fewer side effects, increased medication compliance and higher scores on quality of life assessments compared to people taking twice daily tacrolimus immediate release.
Study to compare pharmacokinetics of tacrolimus prolonged-release (PR) capsules and Advagraf® PR capsules in stable kidney transplant patients.
At present, the number of end-stage kidney disease patients is increasing. Kidney transplant surgery is one of the treatments that give patients a better survival rate than hemodialysis or abdominal dialysis. In Thailand, there were 5,729 kidney transplant patients or 88.9 cases per million population in 2012. Among this number, 465 were new surgical patients or 7.2 cases per million population. From the year 2007-2012, the survival rate of the kidney donor from living donor kidney transplant (LDKT) was 98.5 percent and 93.3 percent at 1 and 5 years, respectively. The most common cause of graft loss was chronic rejection by 33% of all graft loss. However, 16.1 percent were unknown reasons for graft loss. The research question is "In patients with kidney transplantation who suspected graft rejection" Is it true that doing plasmapheresis or DFPP is no different. The researcher therefore conducted a comparative study. Is plasmapheresis or DFPP effective or different side effects?

This is a Phase 2 Multi-Center Clinical Trial (safety and effectiveness trial) in 60 patients (40 denosumab; 20 placebo) who have had a kidney transplant for 12-months or longer with more than 30% of kidney function. The investigators will test whether denosumab safely improves bone mineral density (BMD) by dual-energy X-ray absorptiometry (DXA) and improves bone strength by high resolution peripheral quantitative computed tomography (HR-pQCT) in the subset of patients recruited at Columbia University Irving Medical Center. These data will inform the development and execution of a larger trial to test if denosumab prevents fractures in kidney transplant recipients.
