Filter by:The coronavirus (COVID-19) pandemic has created a significant strain on health care resources across the world for managing critically ill patients. Emerging reports from China, South Korea and Italy have reported varying incidence of acute kidney (AKI) ranging from 5-15% with a mortality of 60-80% however there is no systematic assessment of the risk factors, recognition, course and outcomes in patients with and without kidney disease whose course is complicated by AKI1-4. Patients with underlying CKD, immunosuppressed patients with renal transplants and ESKD patients are at high risk for COVID-19 infection and there is limited information on the effect of COVID-19 on the course and outcomes of these patients. The requirement for renal support including IHD, CRRT and sorbent based therapies has been variable and has contributed to the intense pressure on the nephrology and critical care providers for delivering these therapies. As the COVID-19 pandemic expands in the USA and abroad, there is an intense need to understand the epidemiology of the disease and the resources needed for renal support to inform clinical management and public health interventions. In this study, the investigators aim to investigate health care facilities across the world (hospital wards, ICU, outpatient clinics, nursing homes, healthcare centers) to draw a global picture of incidence, risk factors, resources available for treatment and prognosis of acute and chronic kidney disease in patient with COVID 19 confirmed infection. The aim is to identify trends in patients with acute and chronic kidney disease, determine its incidence, treatment and outcomes in different settings across the world. This information will be used to develop and implement educational tools and resources to prevent deaths from AKI and progression of CKD in this and following pandemics.
Infections are common and associated with poor outcomes as well as high financial costs after kidney transplantation. Identifying and implementing strategies to reduce infections after kidney transplantation is important for improving patient outcomes. This study seeks to determine the feasibility of body surface area-based dosing of mycophenolate compared to standard dosing of mycophenolate in a pilot randomized controlled trial.
Donor-derived cell-free DNA (dd-cfDNA) has shown promise as an early marker for cellular injury caused by rejection. dd-cfDNA changes may also indicate other injuries that lead to progressive decline in transplant organ function associated with, in the case of kidney transplantation, the presence of interstitial fibrosis (IF) and tubular atrophy (TA) seen in biopsy specimens. Here, we will study the utility of dd-cfDNA to predict rejection in pancreas and pancreas-kidney recipients.
Renal transplantation is now recognized as the treatment of choice for patients with end-stage renal disease. An optimum anesthetic regimen should enhance the function and perfusion of the transplanted kidney. The aim of this study is to assess & compare the effectiveness of 3 different modalities in this respect: Mannitol, Dopamine and adequate hydration.
Detecting allograft injury and rejection is critical to preventing graft loss. The current standard of care (SoC) relies on serum creatinine (SC) and biopsy to monitor for and identify kidney injury earlier. SC has poor specificity and sensitivity and response to rejection is often delayed. Protocol biopsy is more accurate but involves the risk of complications. A more definitive, less invasive method for monitoring injury and early rejection is needed. We report on the clinical utility of donor-derived cell-free DNA (dd-cfDNA) in transplant recipients' blood, measured using a novel SNP-based mmPCR NGS methodology, to diagnose allograft injury/rejection. In this study, investigators will measure how use of dd-cfDNA changes clinical practice.
Evaluation Dose Adjustments in Kidney Transplant Patients on Immediate Release and Extended Release Tacrolimus
This study is a comparison of the analgesic efficacy of transversus abdominis plane (TAP) blocks with ropivacaine bolus plus continuous ropivacaine infusion via catheters versus single shot TAP blocks with liposomal bupivacaine.
Despite the considerable advances in short-term outcomes, kidney transplant recipients continue to suffer from late allograft failure, and little improvement has been made over the past 15 years. The worldwide scarcity of donated kidneys and the decline in the number of living donor transplants have prompted a variety of efforts to expand the organ supply, such as accepting organs from donors who were older or had comorbidities or other injuries. Two major initiatives from the United Network for Organ Sharing (UNOS), the organization responsible for organ allocation in the US, failed to improve the kidney acceptance rate. First, UNOS introduced the Kidney Donor Risk Index (KDRI) for all kidney offers in 2012. The KDRI is a score that predicts survival of deceased donor kidneys based on 10 donor characteristics and was intended to simplify the process of judging organ quality for clinicians. Second, in 2014, UNOS changed the kidney allocation system so that lower-quality kidneys are offered over wider geographic areas. Despite the ongoing severe organ shortage and these allocation initiatives, the number of discarded kidneys rose from 2,127 (14.9%) in 2006 to 3,631 (20%) in 2016. In this context, the experience of transplant programs outside the US could offer novel approaches to making organ utilization more efficient through the examination of the disposition of organs that are usually discarded in the US. This project aims: 1. To evaluate the potential benefit of transplanting kidneys that would have been discarded otherwise in the US 2. Computer simulation models on real life data to estimate the number of kidney transplants that would have taken place using data from a nationwide cohort study in two countries (France, the US); 3. To evaluate the potential gains in allograft survival years that would result in the US from a less restrictive kidney acceptance practice such as the one from France.
Patients with kidney transplant have blood tests very often. This is normally done in hospital and using a needle inserted into the vein. Two tests are important for kidney transplant patients - creatinine to monitor the health of the kidney; and tacrolimus to measure the level of the medicine which prevents rejection. The investigators would like to compare a fingerprick microsampling method to the standard venous blood. The fingerprick test is the same done by patients with diabetes and we use a microsampling tip which looks like a cotton bud to draw up a small amount of blood. Each tip draws up exactly 10 microlitres which is two drops. The investigators want to compare the results of creatinine and tacrolimus done through the two methods. In the future, this would allow patients to do their creatinine and tacrolimus test at home. The tips dry completely and can be posted to a laboratory. We hope this will make life easier for transplant patients and also help them engage more with the care of their condition.
Renal transplantation is now recognized as a treatment of choice for patients with end-stage renal disease. An adequate anesthetic technique should achieve hemodynamic stability and enhance perfusion of the transplanted kidney. The aim of this study is to assess the use & effects of continuous spinal anesthesia for kidney transplantation recipients, compared with balanced general anesthesia.
