Delayed graft function (DGF) is defined as requirement for dialysis in the first week following kidney transplantation. DGF is a common complication occurring in 39% of the deceased donor renal transplants at the investigators' institution with significant cost and outcome implications. The 3 major risk factors for DGF are donor graft characteristics, recipient factors and perioperative management. The most easily modifiable of these factors is perioperative management, in particular intraoperative fluid therapy. The investigators propose to compare the amount of fluid administered using the current standard of care with the fluid administered when optimizing the cardiac output (CO) using Esophageal Doppler Monitoring (EDM) to guide fluid therapy. EDM measures blood flow in the descending aorta, optimizing stroke volume (SV) and cardiac output (CO) by indicating when fluid administration fails to produce an increase in CO.
Patients with previous malignancies have increasingly been accepted for renal transplantation. However, post-transplant malignancy risk and survival rates of these patients are unknown. Our aim was to assess if previous malignancies pose an unnecessarily high risk of post-transplant malignant tumours and if the organs as a resource are too limited for investment in this patient group.
Patients suffering from end-stage renal disease (ESRD) are dependent on renal replacement therapy (dialysis). The majority of dialysis is facilitated by hemodialysis. For hemodialysis a vascular access is necessary, preferable an arteriovenous fistula (AVF) in which a vein is directly anastomosed to an artery. In order to use the AVF for hemodialysis three criteria have to be met; the minimal flow over the AVF is 600 mL/min, the diameter is at least 6 mm, and the AVF is located less than 6 mm under the skin. Unfortunately, approximately half of the patients (50%) are confronted with an AVF that does not meet these criteria; the so called non-maturation or primary failure. In case of non-maturation the AVF is not only unusable for dialysis, but also requires reinterventions on short- and long-term. Firstly to mature the AVF, and secondly, when the AVF is matured, to keep the vascular access. Using a computational simulation postoperative flow can be predicted. Based on patient-specific duplex measurements, the model can calculate the flow that can be expected following vascular access surgery for all AVF configurations; fore- or upper arm. These calculations lead to an advice which configuration is indicated; a flow that exceeds 600 mL/min, leading to maturation. Potentially the aforementioned 50% of non-maturation can be reduced. The patient then has an adequate vascular access and reinterventions are adverted, resulting in a decrease of costs, hospital demand, and an increase of the patients' quality of life. When the expected reduction of non-maturation is confirmed, the computational tool can be offered to other hospitals.
Renal osteodystrophy (ROD) represents the bone histologic abnormalities resulting from loss of renal function. It starts early during the loss of kidney function and is seen in virtually all chronic end stage kidney disease patients on dialysis (CKD-5D). A major component of ROD is bone loss leading to chronic kidney disease (CKD) associated osteoporosis. Debilitating hip fractures occur in patients with CKD at a rate 4.4 times higher than in the general population, with associated high costs, morbidity and an annual mortality of 64%. CKD osteoporosis is distinctly different from post-menopausal osteoporosis. Presently, no uniformly accepted CKD osteoporosis treatment protocol exists because of challenges related to racially specific bone turnover states. Therefore, most physicians are reluctant to treat this disorder despite the profound impact on health and quality of life, and its association with vascular calcifications. These vascular calcifications confer an increased risk for cardiovascular events which are the major cause of the over 20% annual mortality rate in CKD-5D patients. The goal of the proposed controlled randomized study is to test the concept that CKD osteoporosis can be successfully treated when treatment is individualized by patients' turnover status. The study will demonstrate that reversal of bone loss can be achieved by increasing bone formation in low turnover patients, and by reducing bone resorption in normal or high turnover patients. A second aim of this study is to provide new information whether these treatments will also retard progression of vascular calcifications. Blood tests measuring FGF23, indicators of Wnt pathway activity, bone resorption and formation will be followed to understand potential mechanisms and to evaluate their usefulness for prediction of changes in bone mass and vascular calcifications. CKD-5D patients with established osteoporosis will be enrolled into one of two treatment arms based on bone turnover status. Each arm will be adaptively randomized by race, age and gender into treatment or control groups. In the low turnover arm, teriparatide combined with cinacalcet will be given, and in the normal or high turnover arm, alendronate will be administered. Bone mineral density will be measured at baseline and after one year of treatment by quantitative computed tomography. Calcifications of the coronaries, aorta and heart valves will also be measured at the same times by multi-detector computed tomography. If this proof-of-concept study is successful, it will offer a heretofore unavailable treatment for osteoporosis in CKD-5D patients thus changing the prevailing clinical practice paradigm. This will provide immediate benefit to CKD patients by reducing fracture risk, bone pain, and cardiovascular risk, while greatly improving their quality of life. These improvements will also convey major socioeconomic benefits by decreasing the high associated treatment costs. The proposed study is highly relevant to the National Institute of Diabetes and Digestive and Kidney Diseases' mission of disseminating science-based information to improve the health and quality of life for patients with endocrine, metabolic and kidney diseases.
The purpose of this study is to examine the effect of nutritional supplementation during hemodialysis treatment on beat-to-beat hemodynamics and treatment efficiency in a crossover design.
To explore whether it is feasible to recruit and retain haemodialysis patients into a randomised controlled trial of online cognitive-behavioural therapy to manage distress
This study evaluates the addition of Pecs II block to ultrasound-guided supraclavicular brachial plexus block in patients undergoing arteriovenous graft creation surgery. Participants will be randomised into two equal groups, one receiving supraclavicular and pecs II blocks, the other receiving supraclavicular block and sham block (Grade 1).
CRAD001AAU13 is a substudy of CRAD001A2433. The core study CRAD001A2433 is a 2-year, randomized, multicenter, open-label, 2-arm study evaluating graft function with everolimus and reduced CNI versus MPA and standard CNI in adult de novo renal transplant recipients. Patients in this study may use cyclosporine or tacrolimus as the CNI.
