Active clinical trials for "Kidney Diseases"

The purpose of this study is to find out why patients with chronic kidney disease (CKD) have poor exercise capacity and to explore what causes an increase in blood pressure during exercise (i.e. increased adrenaline levels, or decreased ability of blood vessels to dilate). This study will also test whether or not regular exercise on a bicycle and/or treatment with 6R-BH4 (Kuvan) pills, or histidine and beta-alanine supplementation improves these measures during exercise. 6R-BH4 is currently FDA-approved for use in patients with certain forms of a disease called phenylketonuria, but it is not currently FDA approved for blood pressure or exercise capacity in people with CKD.

PREFERRED-1 is a pilot study for a large randomized, pragmatic, open-label, comparative-effectiveness trial. The pilot will enroll at least 60 patients from at least 6 different hemodialysis centres in Ontario, Canada. Patients on outpatient maintenance hemodialysis at high risk of fragility fracture, will be randomized 1:1 to a denosumab care pathway vs. usual care

In patients with chronic kidney disease (CKD), uremic toxins accumulate when kidney function declines. Those uremic toxins had a greater affinity to circulating proteins are called "protein bound uremic toxins, PBUT." Apart from traditional small or middle molecule uremic toxins, the PBUTs can be rarely eliminated using traditional renal replacement therapy, even using high flux dialysis modalities. Among these molecules identified, indoxyl sulfate (IS), and p-cresol (PC) are mostly studied. Both in vitro and in vivo study, IS and PC are associated with endothelial dysfunction, vascular smooth muscle proliferation, and increased risk for CV outcomes. The uremic toxins (IS and PC) are originated in the endogenous environment, mainly from the protein metabolism, food intake, or produced by gut microbiota. Prevention of IS or PC precursors from being absorbed across the intestinal tract has been extensively studied in the renal literature by use of oral adsorbents. In animal models, activated charcoal reduces the serum concentration of creatinine (cre) and may delay CKD progression by alleviating IS overload. An oral form of non-absorbable surface-modified activated bamboo charcoal (ABC), has been demonstrated to effectively reduce circulating and renal IS levels in animal models. Recently, probiotics, prebiotics or synbiotics have been reported to reduce inflammation, improve kidney function and retard progression of CKD by restoring the symbiosis of gut microflora in patients with CKD. A randomized trial found synbiotics decreased serum PCS without reducing serum IS in non-dialysis CKD. Another study found that synbiotics delayed CKD progression. A systematic review found prebiotic and probiotic therapies reduced IS and PCS in patients with end stage kidney disease (ESKD) on haemodialysis. However, it is unclear whether the results hold true for other patients with CKD. Based on these previous findings, investigators will conduct a prospective randomized open blinded end-point (PROBE) study to see if oral uremic toxin absorbent + probiotics prevent CKD progression. Also, a panel of clinical and biochemical profiles will be checked to investigate possible link between several biomarkers and clinical response.

Twenty participants with end stage kidney disease (ESKD) and burnt-out diabetes, and 20 non-diabetic participants with ESKD will wear a continuous glucose monitoring (CGM) device for 10 days to see if the use of CGM is a better tool to assess glycemic control than glycosylated hemoglobin (HbA1c) in patients with ESKD on dialysis.

To explore the functional changes of P-gp, CYP3A4, OATP1B and BCRP in Chinese people with renal impairment; To explore the effect of dialysis on the functional changes of P-gp, CYP3A4, OATP1B and BCRP in patients with end-stage renal disease; Validation of urotoxic molecules as possible biomarkers that can assess intestinal P-gp function.

POT-GFR-PK is a single dose pharmacokinetic study oral tetrahydrocannabinol (THC) and cannabidiol (CBD) in healthy adult controls and individuals with chronic kidney disease including those treated with in-center hemodialysis.

The SMaRRT-HD trial is a cluster randomized trial of symptom monitoring with supported clinician follow-up using the SMaRRT-HD electronic patient reported outcome measure (ePROM) system versus Usual Care. Approximately 2400 patients at 30 geographically and racially diverse US hemodialysis clinics will be enrolled. The primary trial hypothesis is that regular symptom patient reported outcome measure (PROM) administration with supported clinician follow-up in dialysis care will reduce suffering and improve outcomes by prompting treatment of unrecognized symptoms, and enhancing patient-care team communication. Clinics randomized to the SMaRRT-HD group will adopt the use of SMaRRT-HD for 12 months. SMaRRT-HD is a symptom monitoring system that includes 1) tablet-based symptom reporting using a PROM and 2) supported clinician follow-up consisting of symptom alerts, guidances for symptom management, and symptom tracking reports that are shared with patients. Dialysis clinics randomized to Usual Care will not adopt SMaRRT-HD or any other trial-driven procedures. Usual Care clinics will monitor symptoms through clinical care interactions with participants and by administering a Health Related Quality of Life survey that includes questions about symptoms.

The goal of this pilot study is to explore the utility of Fast Field-Cycling (FFC) imaging in monitoring kidney disease. The main questions it aims to answer are: If FFC imaging can differentiate healthy kidney from kidney disease If there is an association between FFC imaging and standard clinical tests Participants will provide one blood and on urine sample, and will have one FFC imaging scan.

This study is intended to correct an important systemic deficit in the care of chronic kidney disease (CKD), VHA's fourth most common healthcare condition with high mortality and healthcare burden. Currently, many Veterans with CKD have poor awareness of their condition. This leads to suboptimal care. The investigators anticipate that the proposed comprehensive pre-end stage renal disease (ESRD) education (CPE) will enhance Veterans' CKD knowledge and their confidence in making an informed selection of an appropriate dialysis modality, and lead to an increase in the use of home dialysis (HoD) - an evidence-based, yet underutilized dialysis modality. Further, this study will allow us to examine whether such Veteran-informed dialysis choice can improve Veteran and health services outcomes. If successful, this study may deliver a ready to roll-out strategy to meet the CKD care needs of the Veterans and reduce VHA healthcare costs.

The objective of this study is to assess whether supplementation with curcumin could modulate the intestinal microbiota, reducing levels of inflammatory markers of oxidative stress, uremic toxins and inflammasome, in patients with chronic kidney disease in peritoneal dialysis.
