Filter by:This study aims to evaluate the effect of 12 week low-intensity pulse ultrasound (LIPUS) intervention on the maturation of newly constructed autologous arteriovenous fistulas in uremic patients. This study is a prospective, blinded, randomized controlled trial. This trial is divided into two stages. The first stage is a concept validation trial, which is a single center, prospective, blinded, randomized controlled clinical study. Subjects who meet the screening criteria are randomly divided into an intervention group and a control group in a 1:1 ratio. All subjects underwent safety and efficacy evaluations at the 2nd, 4th, 8th, 12th, and 4th week after treatment. After completing a 4-week follow-up of the 20th study subject, an analysis was conducted with the preset goal of achieving a higher maturation rate of arteriovenous fistula in the intervention group compared to the control group at the follow-up point, and the safety of the study was evaluated. The second stage is a key trial, which is a multicenter, prospective, blinded, randomized controlled clinical study. The inclusion criteria, primary and secondary endpoints, and safety endpoints of the study subjects remain unchanged, and the safety and efficacy of the overall population are evaluated.
To evaluate the decreasing rate of blood IL-6, β2-MG and PTH in maintenance hemodialysis patients in the 52nd week compared with routine hemodialysis.
This study exploring the expression characteristics of different cells of peripheral blood after exposure to two kinds of hemodialysis filter membrane materials will help to elucidate the key mechanisms of hemodialysis filter coagulation occurrence, which is an important guideline for reducing the occurrence of adverse events in hemodialysis.
The goal of this clinical trial is to compare the efficacy of gabapentin with loratadine in reducing the severity of uremic pruritus in patients of chronic kidney disease and to compare the side effects of both drugs. The main questions it aims to answer are: - Which drug (gabapentin versus loratadine) is more effective in reducing the severity of uremic pruritus? - Which drug (gabapentin versus loratadine) has fewer side effects? Participants were divided into two groups.Group A received loratadine 10mg daily and group B received gabapentin 100mg daily. Both groups were given treatment for 4 weeks. - Participants were asked to grade the severity of pruritus on a numerical rating scale and also answer the Dermatology Life Quality Index Questionnaire (DLQI) - Participants were also asked to report any side effects, if occurred. Researchers compared both groups with regards to improvement in pruritus severity, DLQI score and side effects.
This study is a single-center, open-label, randomized controlled clinical study to evaluate the effect of Paxlovid on the virus-negative time and disease progression in uremic patients infected with SARS-CoV-2 (omicron variants). This study will enroll maintenance hemodialysis patients infected with SARS-CoV-2 (omicron variants). After signing the informed consent form, the qualified subjects will be randomly stratified 1:1 to standard-of-care (SOC) or SOC plus Paxlovid for five days.
This project will examine the dysregulation of the urea cycle in patients with terminal uremia using a validated method named "Functional Hepatic Nitrogen Clearance"
Chronic renal failure (CKD) affects 3 million people in France and is characterized by the accumulation of uremic toxins (UTs) such as p-cresyl sulfate (PCS) and indoxyl sulfate (IS) which participate in cardiovascular complications and disturbance of the carbohydrate metabolism associated with CKD. These UTs are not eliminated by dialysis due to their high affinity for albumin and alternative strategies to dialysis must be developed to decrease the production of TUs in patients not yet in dialysis. The dysregulation of the intestinal microbiota observed during CKD increases the generation of UTs in the intestine, by the transformation of amino acids derived from proteins (such as tyrosine and tryptophan transformed respectively into PCS and, IS). Thus, modulation of the intestinal microbiota seems to be an attractive target for reducing the production of UTs and the comorbidities associated with CKD. Some studies have demonstrated the potential interest of probiotics in lowering the plasma concentration of UTs, but the effects remain unclear. In order to test the interest of probiotics during CKD, the investigators have, in collaboration with the Nestlé laboratory and the ProDigest platform, the possibility of testing probiotics using a human intestine simulator before the investigation of experimental and human models. For this the investigators would need a collection of fresh stools. The fresh stools will be instilled in artificial intestine to test the efficacy of selected probiotics on UTs production.
Antibacterial properties of urea was tested against 35 isolates from ocular infections.
Background: Severe acute kidney injury (AKI) among critically ill patients is sometimes treated with renal replacement therapy (RRT), and in Sweden continuous RRT (CRRT) is the dominant modality used in this population. - The optimal timing of renal replacement therapy (RRT) initiation in critically ill patients with acute kidney injury (AKI) is unknown - No consensus to guide clinical practice on this issue - Lack of consistency regarding outcome measurements; should we look at morbidity or mortality? - Wide variability in the timing of RRT initiation in the intensive care unit (ICU) population Hypothesis: This is an important knowledge gap in the support of critically ill patients with AKI and we hypothesize that early initiation of RRT is beneficial. Methods: The present study aims to test this hypothesis by using a large scale high resolution intensive care database, the Clinisoft repository. In this database, we have information on >60 000 patients from three different hospitals and five ICUs, during the years 2005 up until today. The repository will be crossmatched, using the unique Swedish national ID number, with hospital records; to gather information on preexisting illnesses, chronic medication and post-ICU outcomes. It is likely that over 5%, more than 3000 patients, have been treated with RRT. We will categorize these patients into "early" and "late" groups using both biomarker data and clinical data. Importantly, early and late RRT can be categorized using biomarkers, like urea and creatinine; using degree of fluid accumulation, by level of pH in blood and just by using hours-days after ICU admission. All possible definitions of early/late RRT initiation can be tested in this study. Outcomes: Our primary outcome is 90 day mortality. Secondary outcomes include: mortality at 30, 60, 180 and 365 days. Two- and three year mortality. Morbidity, measured as end-stage renal disease (ESRD) for 90-day survivors. ICU length of stay, hospital length of stay.
The Medium Cut-Off dialysis (MCO) membrane has been developed to improve middle molecule removal compared to standard high-flux dialysis filters. The major aim of this study is to compare the reduction ratio of middle molecules, during a single hemodialysis session with MCO-filter, compared to hemodiafiltration (HDF) with standard high-flux filter. Secondary aims are to compare the reduction ratio of small and large molecules between the treatments.
