Filter by:Hypothesis: Valganciclovir prophylaxis can be discontinued before 3 months in CMV-seropositive renal transplant recipients receiving induction thymoglobulin when developing CMV-specific cellular immunity after transplantation. Objective Meet the efficacy and safety of valganciclovir prophylaxis suspend in CMV-seropositive kidney transplant recipients with CD8 + cellular immunity CMV-specific transplant, receiving Thymoglobulin induction and maintain cellular immunity-specific CD8 + CMV after transplantation. Design: noninferiority clinical trial (study A) in CMV-seropositive kidney transplant recipients with CMV-specific cellular immunity pretransplant (Quantiferon reactive CMV) received induction with thymoglobulin Patients meeting inclusion criteria will be randomized to: - Control Arm: valganciclovir prophylaxis until day +90 as recommended by the International Consensus document of the TTS (Transplantation 2013:96:333-360). - Experimental arm: prophylaxis with valganciclovir and determination of CMV-specific cellular immunity day +15, +30, +45 and +60. Prophylaxis was discontinued when the patient developed CMV-specific cellular immunity. Patients who did not develop CMV specific immunity continue prophylaxis until day +90. Analysis: The incidence of CMV disease according to the strategy used was calculated using Kaplan-Meier curves that were compared using the log-rank test.
The investigators will evaluate a technology-enabled strategy designed to promote medication adherence, routinely monitor regimen use, and mobilize appropriate transplant center resources to respond early to kidney transplant recipients demonstrating inadequate adherence.
The aim of this study is to test if alkali treatment will preserve kidney graft function and diminish the progression of chronic kidney disease in renal transplant patients. Additionally the underlying mechanisms of nephrotoxicity of metabolic acidosis will be investigated in this cohort. This study is a multi-center, prospective, randomized, single-blind (patient), placebo-controlled interventional trial to test the superiority of alkali treatment in comparison to placebo on preservation of kidney function in 300 kidney transplant recipients. The duration of the study will be 2 years for the individual participant. The patients will be randomized into 2 arms: intervention arm (sodium hydrogen carbonate, product: Nephrotrans®) and placebo arm (placebo comparator). Several studies in CKD (chronic kidney disease) patients have shown that alkali therapy slows progression of CKD.
Each year, only one third of patients registered on the waiting list receive a kidney transplant. Numerous paths are being explored with the aim of reversing this shortage. The first is to increase the number of organs by developing harvesting from donors in a state of brain-death (BD) termed "expanded criteria donors" or from patients deceased from circulatory arrest. Another fundamental factor is to insure the success of the transplant by limiting the dysfunction of donor kidneys, marked by a delayed graft function (DFG). The development of techniques to insure correct perfusion of harvested organs, and the optimization of reanimation and intensive care of brain-dead donors constitute important factors in DGF reduction. Therapeutic Hypothermia could to be an attractive care strategy for BD patients.
The SPRINT study used a blood pressure measurement procedure that differs from earlier studies in arterial hypertension. SPRINT type readings are lower than regular office measurements. The extent of the disagreement between SPRINT and office measurements may differ in distinct patient groups. This difference is not yet known for patients after renal transplantation. However, it is important to know the difference in order to apply SPRINT findings to transplant recipients.
The purpose of this study is to determine the effectiveness of behavioral feedback plus economic incentives to promote treatment adherence among a large diverse population of adolescents and young adults (AYA) with kidney transplant (KT) or spina bifida (SB).
The aim of this study is to determine if amiloride, a diuretic drug, is capable of increasing renal salt excretion, lowering blood pressure and inhibiting uPA in kidney transplant recipients with proteinuria compared to normoalbuminuric transplant patients.
Demonstrate that low dose (3 mg/kg total ) rATG (thymoglobulin) has similar efficacy (delayed graft function, slow graft function, biopsy proven acute rejection episodes, infections, hospitalizations, adverse events, graft loss and death) than Basiliximab induction
Conventional vascular imaging techniques are often either contra-indicated in chronic kidney disease (CKD) patients due to their relative invasiveness, risks and cost. Computed tomography angiography (CTA) requires radiation and nephrotoxic iodinated contrast which may precipitate significant worsening of renal function and even prompt the need for institution of dialysis. Magnetic resonance angiography (MRA) using gadolinium-based contrast agents has been associated with the rare disease nephrogenic systemic fibrosis. Alternative imaging methods also have drawbacks: for example, this frail patient group has a higher risk of complications from conventional invasive catheter-based angiography, non-contrast-enhanced MRA allows visualization of smaller arteries but is less accurate for larger vascular structures, and ultrasound is often not appropriate for evaluation of the deep vessels of the abdomen and pelvis. Ferumoxytol is an ultrasmall superparamagnetic iron oxide particle encapsulated by a semisynthetic carbohydrate, which was initially developed as a magnetic resonance imaging (MRI) contrast agent in 2000. However, interest in ferumoxytol as a therapeutic agent for the treatment of iron deficiency anaemia in the setting of CKD eclipsed its use as MRI contrast agent. During the last decade, ferumoxytol has gained appeal as an MRI contrast agent in patients with estimated glomerular filtration rates <30mL/min and there are reports in the literature for its safe use and utility in both adult and pediatric patients with CKD. Participants will be selected from those who have been referred for assessment prior to kidney transplant or prior to vascular access creation for haemodialysis and will be divided into three groups. The first group will include patients who will undergo a CTA of abdominal and aortoiliac vasculature as part of their preparation for potential kidney transplantation. The second and third groups will include patients who are having a fistula or a graft created for dialysis, respectively. These patients are routinely having US vascular mapping to visualise the blood vessels before a fistula or a graft is created. Additionally, patients included in the second and third groups are routinely having surveillance scans of their fistula or graft at 6 weeks following creation. Study participants undergoing standard imaging tests as part of their clinical care will also have ferumoxytol-enhanced MRA (FeMRA).
Prospective, single-arm, open-label, multicentre study with the principal aim to estimate tacrolimus pharmacokinetic parameters in elderly de-novo kidney transplant recipients of ECD (Extended Criteria Donor) kidney grafts treated with Envarsus® prolonged release tablets in combination with everolimus tablets.
