Active clinical trials for "Kidney Diseases"

This study aims at evaluating, in chronic kidney disease patients on dialysis, the effect of acute per- or pre-dialytic physical exercise on regional myocardial function and myocardial stunning, blood viscosity, arterial stiffness, variability of sinus rhythm, dialysis efficacy, inflammation, mineral and bone disorders, myokines and cardiac remodeling markers.

The purpose of this study is to assess the safety and tolerability of allogeneic mesenchymal stem / stromal cell therapy in individuals with chronic kidney disease.

Sarcopenia in chronic kidney disease (CKD) affects 50% of dialysis patients and 20% of patients with non-dialyzed CKD and reduce quality of life and survival. The pathophysiology of uremic sarcopenia is multifactorial (accumulation of toxins, metabolic disturbances, etc.) and poorly characterized. These pejorative factors are associated with malnutrition and a sedentary lifestyle. Currently, there are no strategies to combat sarcopenia with the exception of physical activity, which is only possible for a limited number of patients due to their comorbidities. Developing new pharmacological strategies to combat sarcopenia is necessary. FGF19 is a growth factor produced in the ileum involved in metabolic homeostasis. In the laboratory, a new function of FGF19 has been discovered. FGF19 acts as a hormonal factor stimulating muscle mass and strength. Preliminary studies had shown a decrease in the concentration and secretion of FGF19 in response to a meal in haemodialysis patients. However, the link between FGF19, muscle mass and CKD has never been demonstrated. The aim of this study is to assess the relationship between the concentration and secretion of FGF19 and muscle function in a large population of patients with CKD of different stages. Given the hormonal communication between the bone and the muscle, the investigators will also recover the bone histological parameters from a bone biopsy if dialysis patients are to benefit from this as part of their follow-up. The investigators hypothesize that a decrease in FGF19 concentration and secretion in CKD is associated with a decrease in muscle mass and strength.

Immediate release (IR) tacrolimus peaks in the first two hours after administration. These peak levels are influenced by CYP3A5 expression with expressors requiring higher total daily doses with higher peak levels compared to non-expressors. Tacrolimus XR (Envarsus) is a once daily formulation with delayed absorption and lower peak levels while maintaining similar trough levels as seen with IR tacrolimus. A randomized trial of conversion from IR tacrolimus to tacrolimus XR in kidney transplant recipients have shown similar efficacy and adverse events between the two groups but no improvement in estimated GFR. However, urinary biomarkers of acute kidney injury associated with changes in tacrolimus dosing may be more sensitive then serum creatinine. The objective of this study is to assess renal tubular injury in heart transplant recipients who are converted from immediate release to tacrolimus XR. The hypothesis is that the delayed absorption and lower peak levels of tacrolimus XR will lead to less tubular injury and improved renal function without increased risk to the heart allograft.

Chronic kidney disease (CKD) is a serious and growing public health problem. The purpose of this study is to find out if an educational worksheet, called the Encounter Decision Intervention (EDI), combined with health coaching helps CKD patients improve their blood pressure and other health outcomes. The research team hypothesizes that the intervention group will have greater improvement in CKD outcomes than the control group.

This study will determine the efficacy of diuretics in patients with chronic kidney disease.

The GOAL trial addresses patient-prioritised research topics and outcomes and will be conducted, disseminated and implemented in partnership with patients and their caregivers. This will be the first study, internationally, to evaluate the clinical and cost effectiveness of Comprehensive Geriatric Assessment (CGA), a highly promising intervention for improving patient-important health outcomes in frail older people with Chronic Kidney Disease (CKD).

Hispanic/Latino (HL) and American Indian (AI) patients are more likely than whites to have kidney failure, but less likely to complete transplant evaluation or receive a kidney transplant (KT), the best treatment for kidney failure. Using comparative effectiveness research methods, we will conduct a pragmatic randomized trial to compare the efficacy and cost- effectiveness of two approaches to help HL and AI patients overcome barriers to completing transplant evaluation and receiving a KT: a streamlined KT evaluation process and a peer-assisted evaluation program; and, we will determine best practices to assist other transplant centers in implementing the better program. Findings from this work may help reduce disparities in transplant evaluation and KT.

Living donor (LD) kidney transplantation is the optimal treatment for patients with end-stage kidney disease (ESKD). However, LDs take on a higher risk of future ESKD themselves. African American (AA) LDs have an even greater, 3.3-fold, risk of ESKD than white LDs post-donation. Because evidence suggests that Apolipoprotein L1 (APOL1) risk variants contribute to this greater risk, transplant nephrologists are increasingly using APOL1 testing to evaluate LD candidates of African ancestry. However, nephrologists do not consistently perform genetic counseling with LD candidates about APOL1 due to a lack of knowledge and skill in counseling about APOL1. Without proper counseling, APOL1 testing will magnify LD candidates' decisional conflict about donating, jeopardizing their informed consent. Given their elevated risk of ESRD post-donation, and AAs' widely-held cultural concerns about genetic testing, it is ethically critical to protect AA LD candidates' safety through APOL1 testing in a culturally competent manner to improve informed decisions about donating. No transplant programs have integrated APOL1 testing into LD evaluation in a culturally competent manner. Clinical "chatbots," mobile apps that use artificial intelligence to provide genetic information to patients and relieve constraints on clinicians' time, can improve informed treatment decisions and reduce decisional conflict. The chatbot "Gia," created by a medical genetics company, can be adapted to any condition. However, no chatbot on APOL1 is currently available. No counseling training programs are available for nephrologists to counsel AA LDs about APOL1 and donation in a culturally competent manner. Given the shortage of genetic counselors, increasing nephrologists' genetic literacy is critical to integrating genetic testing into practice. The objective of this study is to culturally adapt and evaluate the effectiveness of an APOL1 testing program for AA LDs at two transplant centers serving large AA LD populations (Chicago, IL, and Washington, DC). The APOL1 testing program will evaluate the effect of the culturally competent testing, chatbot, and counseling on AA LD candidates' decisional conflict about donating, preparedness for decision-making, willingness to donate, and satisfaction with informed consent. The specific aims are to: Adapt Gia and transplant counseling to APOL1 for use in routine clinical practice Evaluate the effectiveness of this intervention on decisional conflict, preparedness, and willingness to donate in a pre-post design Evaluate the implementation of this intervention into clinical practice by using the RE-AIM framework to longitudinally evaluate nephrologist counseling practices and LDs' satisfaction with informed consent. The impact of this study will be the creation of a model for APOL1 testing of AA LDs, which can then be implemented nationally via implementation science approaches. APOL1 will serve as a model for integrating culturally competent genetic testing into transplant and other practices to improve patient informed consent.

A 12-week, prospective, multicenter, open-label pilot randomized controlled trial (RCT) will be carried out to determine the feasibility, acceptability and potential clinical efficacy of a newly developed mobile diet app among CKD populations at different stages in Malaysia. Participants will be randomly assigned into either (i) intervention group (mobile diet app) or (ii) control group (dietary counseling using conventional pamphlet).
