Active clinical trials for "Delayed Graft Function"

Established markers of kidney function, such as creatinine, have considerable limitations in the diagnosis of delayed graft function (DGF) after kidney transplantation (KT). Indeed, creatinine does not accurately reflect minor changes of renal function as its levels change only upon significant fluctuations of the latter. CAF22 is a molecule which arises from the degradation of a larger protein and it is proposed to be a reliable and more sensitive marker of renal function. This study aims to further clarify this issue by measuring blood and urine concentrations of CAF22 and comparing them with creatinine levels before and after KT. The main assumption is that blood CAF22 levels could serve as a more sensitive kidney function biomarker than creatinine post-KT to detect DGF.

The primary purpose of this study is to measure the correlation between baseline expression of aging biomarkers, SenesceTest in blood of organ donor and renal graft function. This pilot study will study patients who are undergoing renal transplantation with organs from extended criteria donors, standard criteria donors or donation after cardiac death and compare ability of SenesceTest to predict renal graft function immediately after the transplant and at 1 year followup.

CliniMACs is an investigational device used to select and enrich stem cells. The device will select the stem cells with CD34+ protein. The participant will be infused with the CD34+ selected cells in the hopes that it will help the participant engraft. Engraftment is when transplanted stem cells resume production of healthy blood cells.

The purpose of this study is to determine whether remote ischemic conditioning can improve the outcome after renal transplantation with deceased donor. Remote ischemic conditioning is performed on the patient receiving a kidney from a deceased donor. Remote ischemic conditioning is done during the operation by inflating a tourniquet on the patients leg before opening the blood circulation to the kidney. The study focus on both the immediate kidney function after the transplantation, but also on the extended kidney function one year after the transplantation.

Delayed graft function (DGF) is an important phenomenon after kidney transplantation with direct and indirect implication on graft survival. Although its incidence and risk factors have been studied after cadaveric kidney transplantation cases, only few data is available regarding transplants from living donors. The present study was performed to investigate the frequency and risk factors of DGF among living-unrelated kidney transplant recipients among three transplant centers in part of Middle East.

Hypothermic machine perfusion (HMP) is considered superior to static cold storage (SCS) in kidney transplantation, but the true benefit in the real-world experience remains incompletely understood. The aim of our study is to investigate the real-world impact of HMP on kidney graft function after deceased donor kidney transplant in an HMP cohort propensity score matched with SCS. Propensity score matching will be based on CIT, ECD, gender mismatch, CMV mismatch, re-TX and ET-senior program with a caliper of 0.05

It is required to establish an adequate definition of delayed graft function in deceased donor kidney transplantation. We attempt to compare various definitions of delayed graft function and find the definition that can predict graft function survival best in deceased donor kidney transplantation.

This is a single-center, prospective, non-randomized, observational study to evaluate specific proteogenomic biomarker panels for acute rejection (AR) and chronic allograft nephropathy/interstitial fibrosis and tubular atrophy (CAN/IFTA) in blood, urine and kidney tissue (biopsy) in kidney transplant recipients. Proteogenomic profiles will be routinely monitored over one year after enrollment.

The purpose of this study is to investigate local activation of the coagulation system in the kidney graft during organ preservation and during early reperfusion in adult kidney transplantation. Generation of thrombin and fibrin as well as activation and inhibition of fibrinolysis will be investigated. Influence of these events on delayed graft function (DGF) and acute cell-mediated rejection will be evaluated.

This is a prospective cohort study: First step: to establish a new scoring system for predication of delayed graft function(DGF) following kidney transplantation based on previous and new study data. The new scoring system is comprised of two parts: Xi'an Criteria of donor scoring system and kidney evaluation System based on Lifeport platform ). Second step: validate the new scoring system through prospective cohort study in our transplantation center and modify the scoring system if needed. Recruiting 300 patients, follow up at day 3, week 1, month 1, month 3, month 6 and month 12. Patients will be followed for Cr30cl, DGF,primary non-function (PNF), acute rejection (AR), graft survival and patient survival Step 3: Further validate the new scoring system in six other transplantation centers and developing a software in the end. Recruiting 300 patients, follow up at day 3, week 1, month 1, month 3, month 6 and month 12. Patients will be followed for Cr30cl, DGF, PGF, AR, graft survival and patient survival
