Filter by:The goal of this clinical trial is to understand if and how an animal-assisted intervention [AAI] using therapy dogs can support hemodialysis [HD] patients' treatment adherence and enhance their well-being. The main objectives are: - Objective 1: Determine if the AAI impacts patients' HD treatment adherence (primary outcome is number of unplanned missed treatments no due to hospitalization). - Objective 2: Evaluate if the AAI impacts patients' psychosocial well-being (secondary outcomes are stress, pain, mood, QOL). - Objective 3: Examine potential mechanistic biomarkers that underpin human-animal bonding (hormones tied to stress and bonding). (exploratory aim) - Objective 4: Understand patients' subjective experiences of the AAI. Participants will be asked to engage in several research tasks, including: - assessments - therapy dog visits - monthly blood draws - focus group Researchers will compare how the treatment group (those who receive 2 dogs visits per week) and the control group (those who receive 0 dog visits per week) to see if the AAI impacts treatment adherence and psychosocial well-being.
This study will compare the performance of Gene Expression Profile (GEP)/ Donor derived cell free deoxyribonucleic acid (dd-cfDNA) tests, to the following tests: Molecular Microscope (MMDx) and histopathology (study of changes in tissues caused by disease) in their ability to diagnose (exactly identify) various types of injury within the transplanted kidney.
The purpose of this Phase 1 study is to evaluate the effect of various degrees of renal impairment on plasma pharmacokinetics (PK), safety and tolerability of TNO155. The results of this study will guide the Novartis recommendation regarding whether or not a dose adjustment may be needed when treating patients with renal impairment
Researchers are looking for a better way to treat people who have inflammatory conditions. Inflammatory conditions may result from an increased activation of the body's natural defenses (the immune system) and are characterized by swelling, redness, heat, and pain. The study treatment BAY2395840 is under development for use in inflammatory conditions. It works by blocking a protein, the B1 receptor, whose activation is involved in inflammatory responses. The main purpose of this study is to learn how a single dose of BAY2395840 moves into, through and out of the body in participants with a moderate reduction of kidney function compared to matched participants with normal kidney function. To answer this, the researchers will compare: - the (average) total level of BAY2395840 in the blood (also known as AUC), and - the (average) highest level of BAY2395840 in the blood (also known as Cmax) between the two groups of participants. The participants do not benefit from this study. However, the study will provide information on how to use BAY2395840 in later studies in people with inflammatory conditions. As some people with these conditions may also have kidney problems, this study is done in participants with moderate reduction of kidney function to characterize the use of BAY2395840 in this patient group. All participants will take a single dose of BAY2395840 as tablets. Each participant will be in the study for up to 5 weeks. They will stay in-house for 4 days, including one treatment day. In addition, one visit before and one visit after the in-house phase to the study site is planned.
The mismatch between organ supply and demand results in the deaths of thousands of Americans each year. Our research group aims to solve this unmitigated health care crisis by translating advances in xenotransplantation to humans and expanding organ supply in a sustainable fashion using genetically modified pigs as a source of organs. We propose here a phase I clinical trial of porcine kidney xenotransplantation into 20 people with end-stage kidney disease. Source donor animals are pigs with 10 gene edits (10-GE) which attenuate immunologic harm to the kidney xenograft. 10-GE pigs are housed in a designated pathogen-free facility within 30 minutes of the transplantation center. Xenotransplantation procedures follow conventional practices currently employed in allotransplantation and comply with multiple regulatory standards to ensure ethical treatment of research subjects and source animals. Recruitment and xenotransplantation will occur over 5 years with study follow-up extending 1 year after xenotransplantation. Primary outcome variables surround patient safety, such as patient survival and the rate of zoonotic disease transmission. Secondary outcome variables include commonly used metrics of graft survival and function.
Randomized parallel group study comparing the renal safety of Captisol-Enabled™ Iohexol (CE-Iohexol) Injection and Omnipaque™ (Iohexol) Injection in patients with impaired renal function undergoing coronary angiography.
Risk of contrast-induced kidney injury is expected to be strongly correlated with exposure time. Studies on the excretion of iodinated contrast material are few and have mostly been carried out in patients with normal renal function. Although case wise reports of persistent renograms have been published, it is not known how long contrast is retained before excretion in patients with eGFR <30 mL/min/1.73m2, nor which of these patients are most susceptible to contrast retention. The current observational study aims to compare contrast elimination time and % contrast excretion in patients with eGFR <30 mL/min/1.73m2, to matched patients (for age, sex and contrast procedure type) with eGFR 30-59 and eGFR >=60 mL/min/1.73m2.
Intravascular iodinated contrast administration has become crucial to modern medicine. Currently it is estimated that over 250 million injections are given each year worldwide during medical scans and interventions. An acute predefined increase in serum creatinine is considered an indicator of acute kidney injury (AKI). When such an acute increase in serum creatinine occurs within 5 days post-contrast in absence of another aetiology, it is assumed to be iodinated contrast administration induced acute kidney injury. For over 50 years now, acute kidney injury caused by intravascular administration of iodinated contrast material has been considered a leading cause of hospital-acquired renal failure. Contrast has been withheld in fear of kidney injury with misdiagnoses and delayed appropriate patient management as a result. Since 2018, it is now widely accepted that only patients with eGFR <30 mL/min/1.73m2 are at risk of renal injury after intravascular iodinated contrast material injection. However, no study to date has been able to distinguish acute kidney injury caused by iodinated contrast administration from that for which no causal link is established, and it is unsure a causal relationship exists. There are several studies, in attempts to evaluate the causal relationship between contrast exposure and nephrotoxicity, that found fluctuations in absence of contrast similar to those considered to be contrast-induced acute kidney injury. Similarly, it is unsure whether longer-term negative outcomes are inherent to the population studied or a result of contrast administration. However, most of these studies are observational and retrospective in nature. The issue with retrospective studies is that they often cannot control for confounders and therefore cannot give us causation, only association. On the other hand, prospective randomized controlled trials comparing intravascular iodinated contrast administration to no contrast are unlikely given evident ethical issues. The current prospective observational study proposes to use intra-patient comparisons of peak change in renal function during periods in absence of- and with contrast to elucidate the relationship between renal function and contrast administration in this population.
Point-of-care (POC) creatinine devices allow rapid measurement of creatinine levels and calculation of estimated glomerular filtration rate (eGFR) which give an indication of renal function. The focus of this assessment is to validate POC measurements to assess kidney function before intravascular iodinated contrast administration in patients with severe renal insufficiency (eGFR < 30 ml/min/1.73m2). It will be evaluated whether discrepancies between POC measurement values and values obtained from standard laboratory assays lie within an acceptable range using Bland-Altman analysis.
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.
