Filter by:Contrast-induced acute kidney injury (CI-AKI) has been recognized as the third most common cause of hospital acquired AKI, after hypotension-associated hypo-perfusion and post-operative AKI. The development of CI-AKI after cardiac catheterization is associated with a significant increase in both short-term and long-term mortality and morbidities, as well as an increase in length of stay and cost. The only marker of renal function that has predictive ability is creatinine and it has significant limitations in identifying patients who will develop AKI. Therefore, a diagnostic test for predicting CI-AKI risk would have widespread clinical utility. The primary purpose of this study is to measure the association between baseline expression of senescence markers in blood using SenesceTest and the occurrence of CI-AKI post cardiac catheterization.
The purpose of this study is to establish normal Magnetic Resonance quantitative values (tissues stiffness, Apparent Diffusion Coefficient values and Blood Oxygen Level Determination values for both renal cortex and medullary tissues and total renal blood flow) for young Autosomal Dominant Polycystic Kidney Disease patients with normal renal function, and normal young adult controls without Autosomal Dominant Polycystic Kidney Disease and normal renal function. Hypothesis: Newer Magnetic Resonance quantitative imaging parameters (tissue stiffness, Apparent Diffusion Coefficient, Blood Oxygen Level Determination levels, Magnetization Transfer and renal blood flow) will have different values in young adult ADPKD patients as compared to normal volunteers.
This Phase I pilot study will evaluate the safety, and tolerability of darTreg infusion for adult, de novo, living donor renal transplant recipients.
This study is a prospective, non-interventional, cross-sectional multicenter survey. The aim is to better understand the current therapy pattern for anemia in chronic kidney disease (CKD) treated with erythropoiesis-stimulating agents (ESAs) and not on-dialysis patient population in Israel. Participating physicians will be requested to complete a satisfaction survey for anemia treatment for eligible patients with CKD not on dialysis. The survey will be completed twice, once at study start and once at six months' follow-up.
The prevalence of diabetes mellitus (DM) is increasing worldwide, suggesting that 45% of diabetics are undiagnosed. DM induces a kidney disease called diabetic nephropathy (DN) which is the largest single cause of end-stage renal disease and dialysis requirement. In South America the prevalence of DM and chronic kidney disease has increased, and great disparity exists among countries in regards to access to the dialysis treatment. It has been considerate that Hispanic origin increases the risk for DM. The South Americans have distinctive habits, culture, environment, behavior and genetic background and the factors involved in DN have not been defined yet. The early kidney lesions such as neoangiogenesis (pathologic generation of the new blood vessels) and extracellular matrix expansion have been described. The vascular endothelial growth factor A (VEGF) has been linked to angiogenesis, but the role of VEGF in DN has not been elucidated yet. VEGF signals mainly through VEGF receptor 2 (VEGFR2). VEGFR2 interacts with alphaV beta3 integrin (AVB3) in kidney. Additionally tenascin C is expressed in the extracellular matrix. Tenascin C and the tenascin C/AVB3 complex have also been linked to angiogenesis, however their roles have not been unveiled yet in the DN. Investigators hypothesize that VEGF signaling and tenascin C play an important role in DN and that VEGFR2, AVB3 and tenascin C interact. The purposes of this study is to characterize social, environmental and biological factors implicated in the DN in Ecuador and define the role of VEGF signaling and tenascin C in the pathogenesis of the DN. Investigators propose to study factors involved in DN in diabetic and non-diabetic adults from general population, with and without DN. In a single time investigators will evaluate demographics data, habits, personal and family history through a survey. Investigators will measure anthropometrics parameters and blood pressure; investigators will quantify blood glucose, glycosylated hemoglobin A1c and proteinuria. In addition investigators will examine the role of tenascin C and VEGF signaling by analyzing paraffin embedded kidney tissue, plasma and urine samples. Characterizing the factors involved in the DN from Hispanic people is key to establish adequate strategies of prevention, diagnosis and treatment in this population. Furthermore elucidating the role of proteins involved in DN may offer valuable tools for the development of new treatments.
Hemodialysis is a procedure that kidney physicians perform when the kidneys fail and can no longer clean the blood and remove extra fluid and toxins from the body. Hemodialysis therefore requires access to reach the blood through either a surgically created permanent fistula or graft or through the insertion of a temporary catheter in one of the large body veins. While the use of fistulas or grafts is preferred because they are permanent, there may be conditions that prevent patients from having them and a hemodialysis catheter may be used instead. The problem with the use of catheters however is that they can become blocked due to the formation of blood clots. Kidney physicians try to resolve occlusion of hemodialysis catheters by injecting a medication called Alteplase which breaks the clot at the catheter site. There is no consensus in the medical community as to how much of the medication should be injected at the occluded catheter site. While some kidney physicians and studies recommend the use of 1.0 mg of the medication at each occlusion site, others recommend that 2.0 mg of the medication should be used. Thus, the purpose of this randomized clinical trial is to compare the effectiveness of 1.0mg versus 2.0mg dose of alteplase in resolving blood clots in hemodialysis catheters. The investigators will recruit patients for the study from a regional hemodialysis unit that is located in southwestern Ontario. Patients who agree to participate in this research and experiences occlusion of their hemodialysis catheters will be divided into two groups; making sure that this division is completely by chance. The first group will receive 1.0mg alteplase, while the second will receive 2.0mg Alteplase. The investigators will collect information on both groups and will run statistical analysis of these information to compare the results of clot resolution between the groups.
Some medications are known to cause kidney damage because the person is allergic to the medication while others cause direct damage to the kidney because they are toxic at certain concentrations. Risk factors for developing kidney damage have been identified for some medications but not for all. Patients who are exposed to these important medications and develop problems with their kidneys may have some genetic risk. The purpose of this study is to determine the genetic risk factors for drug induced kidney injury. A better understanding of the role of genetics for the development of kidney injury from medications will allow us to better select medications, improve effectiveness of treatment and minimize harm.
The study has two objectives based on the intended-use measurements and populations described above. The first objective is to show that relative changes in impedance as measured by the test device (ΔSFI) are strongly correlated with the amount of fluid removed during dialysis (ΔF) for subjects with ESRD and possibly Heart Failure. The second objective is to demonstrate correlation between ΔSFI and relative changes in impedance (ΔZ) as measured by the reference device.
The Southeastern Kidney Transplant Coalition is an academic-community collaboration between partners in the kidney disease community who share the common goal of eliminating health disparities in access to kidney transplantation among African American End Stage Renal Disease living in Georgia, North Carolina, and South Carolina. Volunteer members of this community-based coalition include patients with kidney disease, dialysis facility staff and providers, transplant centers, quality improvement organizations, and patient advocacy organizations. The burden of kidney disease is highest in the Southeast, and yet the rate of kidney transplantation is the lowest in the nation. Further, the investigators research suggests that racial disparities in access to kidney transplantation are concentrated in the Southeast, where African Americans are less likely to access each step in the transplant process. The long-term goal of the investigators Coalition is to use community- based participatory research approaches to develop, test, and disseminate sustainable, community interventions improve access to transplant for African American patients with kidney disease. The Reducing Disparities in Access to kidNey Transplantation (RaDIANT) community study proposes to use community-based participatory research methods to develop a multilevel intervention to reduce racial disparities in access to kidney transplantation. The long-term impact of this application will be to reduce racial disparities in the kidney disease community.
The purpose of this study is to examine the effects of a nurse-led case management programme on home exercise training for haemodialysis patients. We hypothesised that: a. There is no significant difference in physical functioning between participants receiving the nurse-led home exercise training programme and those receiving the comparison care. b. There is no difference in depression between participants receiving the nurse-led home exercise training programme and those receiving the comparison care. c. There is no difference in quality of life and health perception between participants receiving the nurse-led home exercise training programme and those receiving the comparison care. d. There is no difference in physical activity levels between participants receiving the nurse-led home exercise training programme and those receiving the comparison care. e. There is no difference in perceived benefits and barriers of exercise between participants receiving the nurse-led home exercise training programme and those receiving the comparison care. The study was a randomized controlled trial conducted in two haemodialysis units of two tertiary hospitals in Nanjing, China. Participants were randomly assigned to either study group or comparison group. Participants in both groups received the in-center exercise training (20 minutes) before haemodialysis sessions weekly for 6 weeks and were instructed to perform exercise at home. The in-center training was focused on flexibility and strengthening exercise. Patients were encouraged to have cardiovascular exercises at home which will improve their cardiovascular conditions and endurance. The list of cardiovascular exercise included brisk walking, bicycling, jogging. Participants in the study group were instructed to start walking or brisk walking at low duration and gradually progress to a maximum of 30 minutes daily per week. To facilitate exercise progression, the nurse case managers discussed exercise benefits, explored exercise barriers and developed mutual goals with patients. The nurse motivated them and checked the exercise behaviors to ensure adherence to the recommended exercise regime. The nurse case managers interviewed the study group patients weekly for six weeks and biweekly for another six weeks. Participants in the comparison group only participated in the in-center exercise training. The comparison group patients received usual care from the nurse without the interviews and mutual goals developed.
