Chronic Kidney Diseases

This study will adopt a 2-arm, pretest-posttest, and assessor-blind RCT design to examine the effectiveness of a theory-based health behaviour change intervention on WC (primary outcome), kidney function (eGFR, primary outcome), dietary behaviour, PA, exercise capacity, and self-efficacy of dietary behaviour and PA among Chinese adults with metabolic syndrome and chronic kidney disease. A total of 160 adults with metabolic syndrome and chronic kidney disease will be recruited, with 80 participants in each group. Data will be collected at 4 time points (baseline, immediate post-intervention, 1-month post-intervention, and 6-month post-intervention) via an online questionnaire survey platform (Qualtrics) by researchers blinded to the group allocation to reduce the detection bias.

The goal of this is to test the efficacy of a 12-week physical activity intervention in 64 adolescents with CKD.

This pilot study will evaluate the feasibility of using a clinical decision support(CDS) message to support consideration of SGLT2 inhibitor prescribing in patients with type 2 diabetes who recently had acute kidney injury. Participating M Health Fairview primary care clinics will be randomized to either receive the clinical decision support intervention or continue usual care. In intervention clinics, providers or clinic pharmacists will receive a message before a scheduled encounter with an eligible patient. The message is intended to support clinical decision-making about SGLT2 inhibitor use, but prescribing decisions will remain with the patient's usual clinical care team. The study will assess feasibility outcomes, including identification of eligible patients, delivery of clinical decision support (CDS) messages, provider/pharmacist receipt of CDS messages, SGLT2i consideration, SGLT2i prescribing, and availability of follow-up kidney function data in the electronic health record.

This cross-sectional study aims to assess body composition and hydration status using bioelectrical impedance analysis in children with chronic kidney disease.

CAPTIVATE is an international, multi-centre, Phase III, adaptive, platform, randomised controlled trial in people with chronic kidney disease (CKD). CAPTIVATE aims to find the best treatment, or combination of treatments, that slow the progression of CKD so that fewer people develop kidney failure. CAPTIVATE provides a research platform that allows many treatment-related questions to be answered within a common trial set-up. CAPTIVATE includes multiple domains examining different therapies for CKD. Participants may enrol in one or more domains and domains will be added and closed over time. The platform operates under a core protocol with each domain described in a domain specific appendix.

Background: Hypertension, together with poorly controlled blood pressure (BP) are known risk factors for kidney disease and progression to kidney failure as well as increased cardiovascular (CV) morbidity and mortality. Several studies in patients without kidney disease have demonstrated the efficacy of home BP telemonitoring (HBPT) for BP control. Objective: The primary aim of this study is to assess the mean difference in systolic BP (SBP) at 12 months, from baseline in remote dwelling patients with hypertension and chronic kidney disease (CKD) in Northern Alberta, Canada, comparing HBPT + usual care versus HBPT + a case manager. Other secondary objectives, including cost-effectiveness and acceptability of HBPT as well as occurrence of adverse events will also be assessed. Methods Design: This study is designed as a pragmatic randomized controlled trial (RCT) of HBPT plus clinical case management compared to HBPT with usual care. Setting: Peace River region in Northern Alberta Region, Canada. Patients: Primary care patients with CKD and hypertension. Measurements: Eligible patients will be randomized 1:1 to HBPT + BP case management versus HBPT + usual care. In the intervention arm, BP will be measured 4 times daily for 1 week, with medications titrated up or down by the study case manager until guideline targets (systolic BP \[SBP\]: \<130mmHg) are achieved. Once BP is controlled, (i.e., to guideline-concordant targets), this 1-week protocol will be repeated every 3 months for 1 year. Patients in the control arm will also follow the same BP measurement protocol, however, there will be no interactions with the case manager; they will share their BP readings with their primary care physicians or nurse practitioners at scheduled visits. Limitations: Potential limitations of this study include the relatively short duration of follow-up, possible technological pitfalls, and need for patients to own a smartphone and have access to the internet to participate. Conclusions: As this study will focus on a high-risk population that has been characterized by a large care gap, it will generate important evidence that would allow targeted and effective population-level strategies to be implemented to improve health outcomes for high-risk hypertensive CKD patients in Canada's remote communities.

The purpose of this study is to establish if concomitant renal and vascularized urinary bladder allograft transplantation is feasible.

This study is a single-center, prospective, randomized, open-label clinical trial evaluating three commercially available closed-incision negative pressure wound therapy (ciNPWT) devices: NPseal, PICO, and Prevena, in adult patients undergoing primary total knee arthroplasty (TKA) who meet predefined high-risk criteria for wound complications. A total of approximately 300 participants will be enrolled and randomized in a 1:1:1 fashion to receive one of the three study dressings applied over the closed surgical incision at the end of the procedure. All participants will otherwise receive standard perioperative and postoperative care. The primary follow-up period will extend through 90 days after surgery. The primary objective is to compare the incidence of 90-day surgical site complications, including superficial infection, wound dehiscence, seroma, and hematoma, across the three dressing groups. Secondary objectives include evaluation of device usability, patient experience, and device-related issues (such as loss of seal, alarms, tubing or pump problems, fluid saturation, and premature dressing changes), as well as assessment of the interaction between skin closure method and device performance. Research-specific activities are limited to eligibility confirmation, informed consent, randomization, administration of a brief postoperative patient survey at approximately postoperative day 7 and/or dressing removal, provider assessment of the dressing at removal, and collection of clinical outcomes from the medical record. No additional blood draws, imaging, or invasive procedures are required for participation. This study is designed to address a gap in the literature by providing head-to-head comparative data on commonly used ciNPWT systems in a high-risk primary TKA population, with the goal of informing postoperative wound management strategies in clinical practice.

In health, blood pressure (BP) falls at night by \>10% compared with day-time values. This natural dipping pattern is important as without it there is an increased risk of cardiovascular disease (CVD). Recent evidence suggests that chronotherapy (taking anti-hypertensive medication at bedtime instead of in the morning) may enhance nocturnal BP dipping and reduce the risk of CVD events. There is therefore an urgent need to characterise diurnal BP patterns in patients who may be at risk of reduced nocturnal dipping in order to maximise protective therapy in all those who would benefit. Similarly, it has previously been demonstrated that increased arterial stiffness is associated with increased CVD risk, however little is known about whether loss of diurnal variations in arterial stiffness confer addition risk. Kidney disease is independently associated with increased CVD events, but the exact makeup of this risk is not clear. Within this heterogenous cohort several very distinct groups exist including those with acute kidney injury (AKI), chronic kidney disease (CKD), inflammatory conditions like small vessel vasculitis (SVV), and those who have either donated or received a kidney transplant. Diurnal BP and arterial stiffness patterns within these patient groups are not well characterised. The investigators will recruit patients at increased risk of CVD from the Royal Infirmary of Edinburgh Renal and Vasculitis Clinics. Participants will undergo 24-hour ambulatory BP and arterial stiffness measurement in conjunction with day- and night-time blood and urine sampling on two separate occasions. This study aims to characterise diurnal patterns of BP and arterial stiffness in patients at increased risk of CVD and compare findings with healthy controls. In doing so, the investigators aim to allow more targeted CVD risk reduction strategies and improve long-term patient outcomes.

The aim of this clinical trial is investigate the comparative effectiveness of empagliflozin and dapagliflozin for the treatment of diabetes, chronic kidney disease, and heart failure. Patients who are prescribed either empagliflozin or dapagliflozin, as part of daily clinical practice at the participating sites, will be included in the study. Treatment will be randomized automatically through the electronic health record software in clusters defined by time of day. https://www.appletreestudy.com

This study tests the efficacy of a dyadic intervention to mitigate the adverse health consequences of adults with pre-existing chronic health conditions and their informal carepartners (IC). Socioeconomically disadvantaged, older, and people from rural regions are more likely burdened with greater rates of chronic diseases such as diabetes, hypertension, chronic kidney disease, cardiovascular disease, and stroke.

This cross-sectional study aims to determine the prevalence of secondary hyperparathyroidism among end-stage renal disease patients on regular hemodialysis and to evaluate its relationship with dialysis adequacy at Assiut University Hospitals.

Calciphylaxis, a vascular calcification disorder, is a rare and serious disorder characterized by calcification of dermal arterioles. There are significant gaps in the understanding of the pathophysiology and risk factors for calciphylaxis. At present, there is no effective treatment. Uncertain pathobiology, rare incidence and lack of collaborative approach have been some of the major limiting factors towards treating calciphylaxis. The Partners Calciphylaxis Biorepository (PCB) aims to address these gaps within calciphylaxis research by utilizing existing and, when necessary, developing new infrastructure to support the consent of patients and the collection of dedicated samples for a calciphylaxis repository.

This cross-sectional study aims to assess awareness regarding arteriovenous fistula creation among patients with advanced chronic kidney disease, including pre-dialysis patients and those receiving maintenance hemodialysis, at Assiut University Hospital.

The proximal tubule remains the main site for sodium reabsorption in patients with advanced renal failure. The investigators therefore hypothesize that SGLT2i should still exert a significant natriuretic effect in patients with eGFR below 20 ml/min/1.73m2, and therefore should still decrease proteinuria with a potential renal protective effect.

This comparative cross-sectional study aims to determine the prevalence of subclinical renal dysfunction in patients with rheumatoid arthritis and to evaluate its association with disease activity and inflammatory markers compared with age- and sex-matched healthy controls at Assiut University Hospitals.

Phase III, multicenter, randomized, open-label, parallel-group, non-inferiority, phase III clinical trial comparing CSZ (Lokelma) vs. iSRAA discontinuation/reduction and/or ARM (standard treatment).

The purpose of this study is to see if 6 months of home-based walking will improve memory, and brain structure and function, compared to health education in older adults that have chronic kidney disease and mild cognitive impairment.

This prospective observational cohort study aims to identify independent predictors of rapid chronic kidney disease (CKD) progression and determine its incidence among predialysis CKD patients. A total of 190 adult patients will be enrolled from the nephrology outpatient clinic and inpatient ward at Assiut University Hospitals and followed for 24 months. Rapid progression is defined as a sustained decline in eGFR \> 5 mL/min/1.73 m² per year according to KDIGO 2024 criteria. Clinical and laboratory parameters will be assessed at baseline and during follow-up to identify predictive factors

Rationale: * People with long term kidney disease who are on haemodialysis (a procedure for removing waste products from the blood) commonly develop a condition that makes their skin very itchy. * Difelikefalin is a medicine that can treat the itching related to long term kidney disease. * Clinical studies have shown difelikefalin to reduce itching in adults on haemodialysis, while being safe and tolerable. * The current study is being done in adolescents aged 12 to 17 years on haemodialysis who have moderate to severe itching related to long term kidney disease to assess if difelikefalin is safe in this age group. The aims of the study are: Main aim: To assess the safety of difelikefalin in adolescents who are on haemodialysis and have itching related to long term kidney disease Secondary aim: To measure the amount of difelikefalin that enters the blood in adolescents who are on haemodialysis and have itching related to long term kidney disease Study Design At least 18 adolescents, aged 12 to 17 years, who are on haemodialysis and have itching related to long term kidney disease will take part in this study. All study participants will receive difelikefalin 3 (or up to 4) times weekly for up to 12 weeks. The study duration for a participant is up to 17 to 18 weeks; during this period, participants will visit the clinic 3 times weekly (during their haemodialysis visits).

The purpose of this study is to evaluate the long-term safety of up to two gelatin-hydrogel formulation REACT injections given 3 to 6 months apart and delivered percutaneously into same kidney on renal function in participants with chronic kidney disease (CKD).

The goal of this pilot randomized controlled trial is to examine the feasibility and safety of a 12-week high-velocity resistance training (HVRT) intervention in older adults with chronic kidney disease (CKD) stages 4-5 and to generate preliminary data to inform a future study investigating the efficacy of HVRT for improving muscle power and physical function. Researchers will compare HVRT to an attention control condition consisting of weekly group sessions covering topics on healthy lifestyle. This study seeks to: 1. Determine whether implementing an HVRT intervention is feasible and safe for mobility-limited older adults with advanced CKD. 2. Collect preliminary data on the efficacy of HVRT for improving muscle power and physical function in mobility-limited older adults with advanced CKD.

Primary Objective: To study podocyte specific injury markers in African American Veterans with non-diabetic kidney disease (NDKD), on empagliflozin therapy. Primary Endpoint: We will assess the effect of Empagliflozin on podocyte-specific proteins in exosomes isolated from subjects' urine, such as nephrin, podocalyxin and Wilms'Tumor (WT-1) protein. Secondary Objectives: 1. Correlate changes in exosome-based podocyte specific proteins with standardized biomarkers of kidney injury including urine albumin/creatinine ratio (ACR) and estimated GFR. 2. Correlate systemic inflammatory markers (focusing on vascular and endothelial function) that are already established such as interleukins (IL1, IL6, IL-12) , hs-CRP and arterial stiffness measures with urine exosome-based podocyte protein estimation \[11, 27-29\]. 3. Correlate urine podocyte-specific protein markers with APOL1 mRNA expression levels in blood mononuclear cells (MNC)

The goal of this study is to learn if a clinical trial of sodium-glucose co-transporter 2 inhibitors (SGLT2i) is possible in youth with chronic kidney disease (CKD). The investigators also plan to explore whether treatment with SGLT2i (Empagliflozin) helps improve risk factors for worsening kidney and heart disease. The main questions are: 1. Is enrolling 40 youth with CKD into a clinical trial of empagliflozin feasible (ie achievable)? 2. Does taking empagliflozin for 3 months result in positive changes in blood, urine, and heart function tests? Participants will be randomly selected (like flipping a coin) to either receive empagliflozin or not start treatment with empagliflozin and remain on their usual care. Study Procedures Include * For participants randomly selected for treatment, take empagliflozin once daily for 3 months * Phone calls with researchers every 2 weeks for check-ins * For participants taking empagliflozin, clinic visits 4 and 8 weeks after starting for check-ups and tests * All study participants will have clinic visits at the beginning and end (3 months) where researchers will collect information about their health and perform tests

The objective of this initiative is to develop and evaluate a risk-based, provincial public health screening program for chronic kidney disease (CKD) that provides proactive care for adults at high-risk of kidney failure who have not previously been referred to a nephrologist, through risk stratification, triage, education, and follow-up. Overall, we aim to demonstrate that an integrated risk-based provincial public health screening program for CKD is feasible, and improves identification of high-risk individuals, subsequently creating a model of care that can be adopted by other jurisdictions.
