NCT05348733
This is an observational study in people with chronic kidney disease (CKD) and type 2 diabetes (T2D) who will be receiving finerenone. Kidneys filter extra water and waste out of the blood and make urine. CKD is a long-term, progressive, decrease in the kidneys' ability to filter the blood properly. In people with T2D, the body does not make enough of a hormone called insulin, or does not use insulin well enough, resulting in high blood sugar levels that can cause damage to the kidneys. As a result, CKD can occur as a complication of T2D. Finerenone works by blocking certain proteins, called mineralocorticoid receptors. An increased stimulation of these proteins is thought to damage the kidneys and the heart. By lowering their stimulation, finerenone reduces the risk of kidney disease progressively getting worse. Finerenone is available and approved for doctors to prescribe to people with CKD and T2D. Since it has only recently become available for these patients, there is a need for more information about the use of finerenone in the real-world setting. The main purpose of the study is to learn more about treatment patterns in people with CKD and T2D who just started or will start finerenone treatment as decided and prescribed by their doctor as part of their routine medical care. To answer this question, the researchers will collect data on: * Clinical characteristics (e.g., history of CKD and T2D, blood pressure, heart health) of the participants * Reasons for starting finerenone * Reasons for stopping finerenone early * How long participants have been taking finerenone (planned by their doctor compared to actual time it was taken) * Dosing of finerenone * Other medications used while taking finerenone The researchers will also collect data on medical problems (called adverse events) that the participants may have during the study. All adverse events are collected, even if they might not be related to the study treatment. Hyperkalemia, a medical term used to describe a potassium level in the blood that is higher than normal, is of special interest when finerenone is combined with some medications commonly taken to control blood pressure. Researchers want to know how often higher potassium levels occur, and when it leads to: * Stopping finerenone treatment too early * Dialysis (a medical procedure to filter the blood of extra water and waste) * Care in a hospital All data will come from medical records or from interviews study doctors will have with the participants during visits that take place during routine medical care. Participants in the US will be invited to provide voluntary blood and urine samples that could be analyzed later to better understand possible changes in protein or nucleic acid levels over time. Each participant will be in the study for 12 months. This time participating in the study may be shorter if their finerenone treatment is stopped early or the study comes to an end as planned in September 2027.
NCT07415421
This study aims to clarify whether surgical treatment of persistent hyperparathyroidism after kidney transplantation offers clinically meaningful benefits compared with a conservative treatment strategy. Kidney transplant recipients (\>6 mo after transplantation) with persistent hyperparathyroidism (elevated PTH and either hypercalcemia or hypophosphatemia) will be randomized in a 1:1 ratio to either subtotal parathyroidectomy or conservative management according to standard clinical practice. The study is conducted as an open-label, randomized controlled pilot trial with a 12-month follow-up period. Outcomes include bone density, physical function, quality of life and symptom burden.
NCT07271186
This study is researching experimental drugs called ALN-ANG3 and evinacumab (called "study drugs"). The study is focused on participants who have diabetic kidney disease. The aim of the study is to see how safe and effective the study drugs are. The study is looking at several other research questions, including: * What side effects may happen from taking the study drug * How much study drug is in the blood at different times
NCT07377461
Kidney stones located in the kidney are commonly treated using a minimally invasive procedure called retrograde intrarenal surgery (RIRS). During this procedure, a ureteral access sheath is often used to facilitate repeated access to the kidney, improve visualization, and allow irrigation fluid to drain. Newer access sheaths have been developed with flexible distal tips and built-in suction capabilities, which may help reduce operative time by improving visibility and removing stone fragments and irrigation fluid more efficiently. This prospective randomized study compared a flexible and navigable suction ureteral access sheath with a conventional ureteral access sheath in adult patients undergoing RIRS for kidney stones measuring 10 mm or larger. Participants were randomly assigned to one of the two access sheath types. The primary objective of the study was to evaluate whether the use of a suction-enabled access sheath reduces operative time. Secondary objectives included assessment of complications, length of hospital stay, stone-free rate, and need for additional interventions.
NCT06474169
This is a comparative, prospective, non-interventional study to evaluate immune response in patients with chronic kidney disease. The primary objective is to define immunodeficiency (phenotype and function of T cells) in patients with end-stage kidney disease. The second objective is to provide an in-vitro proof-of-concept of T-cell engineering in the context of end-stage kidney disease. The study population was patients with chronic kidney disease.
NCT07655050
Retrograde intrarenal surgery (RIRS) is a widely used treatment for kidney stones; however, postoperative infectious complications remain a significant concern. This prospective randomized factorial trial aims to evaluate whether gentamicin-containing irrigation fluid and the use of a suction ureteral access sheath can reduce postoperative fever, systemic inflammatory response syndrome (SIRS), and sepsis after RIRS. The study will also investigate the independent and combined effects of these two interventions on infectious outcomes.
NCT02889575
Acute Renal Failure (ARF) is defined by a severe, and usually reversible, glomerular filtration rate decreasing. Acute Tubular Necrosis (ATN) remain the major cause of ARF involving distress and destruction of tubular cells. This specific typology of ARF may evolve toward Chronic Renal Failure (CRF) concretizing a major public health issue. Predict the progression of ARF towards CRF appears essential. The investigators believe that the PIIINP and urinary NGAL biomarkers may constitute robust biomarkers of progression risk towards CRF.
NCT05853601
Acute kidney injury is a significant complication for infants who experience hypoxic ischemic encephalopathy, being associated with increased rates of death and prolonged hospitalization. This pilot study of theophylline administration soon after birth for the prevention of kidney injury will lay the foundation for the conduct of a larger clinical trial that seeks to identify a theophylline as a novel therapy to prevent kidney injury in thousands of at-risk infants.
NCT07465926
This retrospective observational target-trial emulation uses electronic health record data from the TriNetX US Collaborative Network to compare early treatment intensification strategies in adults with obesity, type 2 diabetes, and cardiovascular-kidney-metabolic stage 2-3 who initiate a GLP-1 receptor agonist or an SGLT2 inhibitor. The study compares patients who, within 90 days of starting background therapy, add the alternate agent, add a DPP-4 inhibitor or sulfonylurea, or do not receive early add-on therapy. The primary outcome is all-cause mortality over 36 months, with secondary cardiorenal outcomes also evaluated. Propensity-score methods are used to reduce bias from nonrandom treatment selection.
NCT07654231
The overall objective of this pilot randomized clinical trial is to determine whether low-dose Colchicine (LoDoCo) improves vascular disease including vascular calcification, peripheral arterial disease (PAD), and chronic kidney disease-mineral and bone disorder (CKD-MBD) biomarkers in patients with chronic kidney disease (CKD) stage 3 over a 12-month intervention period, compared with usual care. Successful completion of this study will generate critical preliminary data to support a larger clinical trial aimed at evaluating inflammation-targeted therapies to mitigate CKD-MBD, including vascular calcification and related PAD, as well as osteoporosis, ultimately reducing cardiovascular events and mortality in patients with CKD. Additionally, this work has the potential to redefine the diagnostic framework for CKD-MBD.
NCT07657338
This study is a randomized controlled pilot trial designed to evaluate the effects and safety of a traditional Chinese medicine formula (CKD-1) as an add-on therapy to standard treatment in patients with stage 3-4 non-diabetic chronic kidney disease. Eligible participants will be randomly assigned to receive either standard care alone or standard care combined with CKD-1 for 12 weeks. Kidney function, urine protein levels, and quality of life will be assessed before and after the intervention. The study aims to provide preliminary evidence on whether CKD-1 can improve renal function and quality of life in this patient population.
NCT02502071
The purpose of this study is to determine whether alkalinization of urine uric acid by 2 doses of sodium bicarbonate (1950mg) over 24-hours reduces precipitation and crystallization of urine uric acid over in adults with type 1 diabetes.
NCT07380113
The goal of this clinical trial is to compare a new intravenous drug, Anruikefen, with a traditional oral medication, nalfurafine orally disintegrating tablets, in improving sleep quality in patients with chronic kidney disease-associated pruritus. Sleep quality will be primarily assessed using the Pittsburgh Sleep Quality Index (PSQI). The study will also evaluate the safety of Anruikefen. The main questions it aims to answer are: * Does Anruikefen injection improve sleep quality better than oral nalfurafine? * Does Anruikefen injection improve patients' quality of life more than oral nalfurafine? Researchers will compare Anruikefen with nalfurafine (an active control drug) to evaluate differences in their effects on sleep quality in patients with chronic kidney disease-associated pruritus. Participants will: * Receive either Anruikefen injection (0.3 μg/kg, three times per week) or nalfurafine hydrochloride orally disintegrating tablets (2.5 μg once daily). * Continue treatment for 4 weeks, followed by a 1-week safety follow-up. * Complete the Pittsburgh Sleep Quality Index and other quality-of-life questionnaires after one month.
NCT04748770
Obesity is in constant increase all over the world and affects 35% of the global population according to the World Health Organisation. It is associated with other cardiovascular risk factors (particularly hypertension and diabetes) and with high morbi-mortality. It is also responsible for an increase of the risk of developing chronic kidney diseases (CKD). In fact, obese patients represent 25% of the dialysis population and Picardy is one of the most affected areas. However, their access to kidney transplant is still restricted and the reasons are not completely understood.
NCT07595952
Background: Randomized clinical trials (RCTs) are essential for evaluating intervention effects but are often challenged by regulatory and logistical burdens, high costs, and extended timelines. To address these challenges, the 'Adaptive Platform Trial in Kidney Disease' (APT-KIDNEY) will establish an investigator-initiated platform trial built on a unified regulatory, contractual, and operational framework. The platform emphasizes adaptive, cost-efficient methodology, automated data capture via linkage to electronic health records and administrative registers, and stakeholder engagement. Objectives: The primary objective of APT-KIDNEY is to establish an adaptive platform trial for evaluation of multiple interventions in patients with advanced kidney disease as defined by an estimated glomerular filtration rate \< 30 ml/min/1.73 m2 or end-stage kidney disease (ESKD) on dialysis or conservative care. Study design: APT-KIDNEY is a pragmatic, randomized, embedded, multifactorial, adaptive platform trial with interventions organized into domains, emphasizing low-intervention comparisons. Domains may be open-label or blinded and will be able to use response-adaptive randomization, adaptive stopping and arm-dropping, and adaptive enrichment to enhance efficiency and relevance where applicable. Study population: Adults (≥18 years) with advanced kidney disease defined by eGFR \< 30 mL/min/1.73 m2 for ≥3 months or ESKD on hemo- or peritoneal dialysis who are eligible for ≥1 one domain. Key exclusions include inability to provide informed consent; domain-specific exclusions may apply, but eligibility cannot be broadened beyond the core protocol. Trial outcomes: Core outcomes will be all-cause mortality, major adverse cardiovascular events (nonfatal myocardial infarction, nonfatal ischemic stroke, or cardiovascular death), and health-related quality of life (EQ-5D-5L). Abbreviated methods: APT-KIDNEY will permit domains to use frequentist and/or Bayesian methods. Primary analyses will target prespecified primary estimands and be conducted using the full analysis set. Prespecified sensitivity analyses will assess robustness to alternative strategies for intercurrent events and missing data, including per-protocol and as-treated supportive analyses. Outcomes are analyzed with generalized linear/mixed models and time-to-event methods with covariate adjustment. Frequentist analyses will be fixed-sample or group-sequential; results will be reported with 95% CIs and p-values, and Bayesian analyses will report posterior effects with 95% credible intervals and posterior probabilities. Bayesian domains will primarily use neutral, mildly skeptical priors. Multiplicity will be controlled at the domain level by a prespecified hierarchy: primary comparisons will precede secondary outcomes. Advanced adaptive domains will be evaluated by simulation to quantify operating characteristics including, power and Type I error, and the impact of outcome delays and missing data. Perspectives: APT-KIDNEY will establish an enduring, investigator-led platform for pragmatic, embedded nephrology trials, reducing start-up time and administrative burden through a shared regulatory and operational framework. Using standardized core outcomes and automated follow-up via electronic health records and national registers, it will generate faster, comparable, practice-relevant evidence across multiple interventions.

Kidney diseases related to the immune system include, nephrotic syndrome, glomerulonephritis, membranous nephropathy, lupus nephritis, and nephritis associated with connective tissue disorders. This study will allow researchers to admit and follow patients suffering from autoimmune diseases of the kidney. It will attempt to provide information about the causes and specific abnormalities associated with autoimmune kidney disease. Patients with kidney disease as a result of their immune system, and patients with diseases of the immune system who may later develop kidney disease, will be potential subjects for this study. Patients will undergo a history and physical examination, and standard laboratory test to more closely understand the causes, signs, symptoms, and responses to medication of these diseases. Based on these evaluations the patients may qualify as candidates for other experimental studies. At any time these patients may be asked to submit blood or urine samples for further research.
NCT07328620
This study aims to investigate the effects of permissive hypotension, which is routinely used in rhinologic surgeries such as rhinoplasty, septoplasty, and functional endoscopic sinus surgery (FESS), on renal function. Although permissive hypotension has been widely practiced to improve surgical field visibility and reduce intraoperative blood loss, its specific definition is not standardized in the literature. In most studies, maintaining mean arterial pressure (MAP) within the range of 50-65 mmHg is considered permissive hypotension. MAP values below 60 mmHg have been associated with increased risk of cardiac and renal complications. However, in otherwise healthy patients, such episodes are frequently tolerated without clinically apparent renal dysfunction. The kidneys have a strong compensatory reserve capacity, and early tubular injury may not be detected by conventional renal function tests such as serum creatinine. Therefore, the use of more sensitive biomarkers is necessary to detect potential subclinical injury. In this prospective observational study, serum NGAL and cystatin C levels will be measured from routine preoperative and postoperative (12-24 hours) blood samples obtained from adult patients undergoing rhinologic procedures. A ≥25% increase in these biomarkers from baseline will be considered indicative of subclinical acute kidney injury. Additionally, intraoperative hemodynamic data will be monitored, and the duration of MAP \<60 mmHg and MAP \<65 mmHg will be recorded. At the end of the procedure, surgical field conditions will be evaluated using the Boezaart Surgical Field Score. The relationship between these parameters and biomarker changes will be analyzed. The goal of this study is to determine whether early, clinically silent renal injury may occur during permissive hypotension and to provide insight into its potential implications for future renal function. All interventions and blood samplings are part of routine care, and no additional procedures will be performed for research purposes.
NCT03877276
The purpose of this study is to evaluate mitochondrial function in white blood cells and platelets from healthy individuals following dietary oxalate intake.
NCT07624578
Kidney cancer in adults is the seventh leading cause of cancer-related death in France. Early and accurate imaging of the primary tumour and the identification of metastatic sites are major prognostic factors that are crucial for determining the appropriate stage-specific treatment. However, the diagnosis of sub-centimetre metastatic lymph nodes and occult metastatic lesions remains difficult with current imaging methods. Recent publications have shown promising results for 68Ga-PSMA PET-CT in the detection of metastases from renal cell carcinoma (RCC). It is therefore necessary to develop a new, more sensitive and specific imaging method to detect occult metastatic foci, enabling the earlier initiation of specific systemic or local treatment, and thereby improving survival in these patients or even achieving prolonged remission in oligometastatic cases Experience and acceptability of a new organisational model in primary care: participatory multi-professional health centres
NCT00352534
This phase III trial is studying vincristine, dactinomycin, and doxorubicin with or without radiation therapy or observation only to see how well they work in treating patients undergoing surgery for newly diagnosed stage I, stage II, or stage III Wilms' tumor. Drugs used in chemotherapy, such as vincristine, dactinomycin, and doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors.Giving these treatments after surgery may kill any tumor cells that remain after surgery. Sometimes, after surgery, the tumor may not need additional treatment until it progresses. In this case, observation may be sufficient.
