Active clinical trials for "Kidney Diseases"

This study is an open-label, multi-center study evaluating the clinical utility of Renasight in the diagnosis and management of kidney disease.

The aim of this study is to gain a better understanding of the phenomenon of adherent perinephric fat (APF), which occurs in some patients undergoing partial nephrectomy (PN). This phenomenon, so-called "toxic fat", is a commonly recognized problem among urologists, but its significance has not yet been fully understood. The study aims to identify new clinical risk factors for APF occurrence and evaluate its impact on functional, perioperative, and oncological treatment outcomes. The study will be conducted on patients who are qualified for PN surgery. Prior to the surgical procedure, venous blood will be collected, which will be used for various measurements, such as blood morphology, kidney parameters, inflammation markers, liver function tests, glucose, and lipid profile. In addition, medical data will be collected concerning the patient's overall health, observed changes in the kidney, perioperative course, hospitalization, and histopathological characteristics of the tumor. After treatment, patients will be followed up for up to 60 months. The knowledge gained from this study can significantly assist in making decisions about surgical treatment and thus contribute to improving the treatment outcomes of patients with kidney tumors.

Haemodialysis is a renal replacement therapy that can be introduced to patients with end-stage renal disease (ESRD) to help them maintain a good healthy life. The patient's blood is pumped through a dialysis machine to remove excess fluid, salt and waste, then it is pumped back into the patient's circulation system. In order to carry out haemodialysis, vascular access (VA) is required to connect the patient to the dialysis machine. Patients have only three options of vascular access: arteriovenous fistula (AVF), an anastomosis between a native vein and an artery; arteriovenous graft (AVG), a connection between a synthetic tube and native blood vessels; and (3) central line, a cuffed catheter placed in a large neck vein. Arteriovenous fistulas are the preferred method for VA because of their longevity and causing the least number of complications. Although there are a number of factors that may increase the probability of AVF failure rate such as age and gender of the patient, poor native vessel structure, medications and the level of surgical experience, 30-40% of new AVFs fail to mature for unknown reasons. For an AVF to become functionally mature postoperative, remodelling and dilation of the native artery and vein are essential to accommodate significantly increased blood flow. However, pre-existing diseases in patients with ESRD such as arterial stiffness and endothelial dysfunction may impair AVF and preclude dialysis. It has been asserted that the lack of AVF success is attributable to insufficient arterial dilation because of poor arterial wall elasticity. The study aims to investigate the role of arterial stiffness and endothelial dysfunction in predicting AVF outcome using novel non-invasive ultrasound applications: 2D shear wave elastography and 2D strain speckle tracking will be employed to assess arterial stiffness, while an intraoperative flow-mediated dilation (FMD) technique will be used to evaluate endothelial dysfunction.

The goals of KNOW-CKD (KoreaN cohort study for Outcome in patients With Chronic Kidney Disease) study are 1) to establish a CKD cohort representing Korean CKD population for up to 10-year follow-up, and 2) to investigate the renal progression, mortality, complications, risk factors, role of biochemical parameters and the genetic influence. KNOW-CKD Phase I has enrolled 2,238 patients and these patients were divided into four major subgroups depending on the specific causes of CKD : glomerulonephritis, diabetic nephropathy, hypertensive nephropathy, and polycystic kidney disease. In progress, renal progression, complications, and cardiovascular disease of these patients are followed up now. Since there was a lack of information related to patients' lifestyle, it is necessary to conduct various studies that can be applied to actual clinical status through evaluation of nutrition, cognitive functions, and lifestyles of patients with CKD in South Korea. In addition, researches for high risk patients including diabetic nephropathy, advanced CKD and elderly patients are needed. Thus, KNOW-CKD phase II will enroll the CKD subjects at a more advanced-stage, and older patients than KNOW-CKD phase I subjects. KNOW-CKD phase II Investigator Group comprises nephrologists, epidemiologists and statisticians from multi-centers in South Korea. KNOW-CKD phase II will enroll 1,500 individuals with estimated glomerular filtration rate between 20 and 60mL/min/1.73m2 (CKD-EPI[Cr] equation) between 2019 and 2021 and follow them until 2016 (for 5~7 years). Unlike phase I, patients diagnosed with glomerulonephritis and ADPKD will be excluded in Phase II.

The current trial is designed to evaluate how the results of KidneyIntelX test / platform impacts on the clinical management of type 2 diabetes patients identified as increased risk for rapid kidney function decline within 5-years.

The main objective of this prospective cohort study is to assess arrhythmia burden and glycemic variability in a multicenter cohort of patients with end-stage renal disease using a sufficient observation period in order to identify arrhythmia burden and type and characterize associations with patient characteristics and dialysis treatment, glycemic variability and subsequent risk of adverse outcomes.

This is a prospective multi-centre, observational cohort study of incident and prevalent patients diagnosed with a kidney disease in China.

Retrospective observational study to investigate acute kidney injury (AKI) epidemiology and outcomes in patients hospitalized in University Hospital San Martino, Genova, Italy.

Kidney biopsy play a key role for the investigation of either acute kidney injury or chronic kidney disease. Despite possible complications due to the invasive nature of the biopsy, such procedure is still essential in a number of clinical situations to improve the diagnosis specificity of kidney disease, better inform about its prognosis and guide the management of a future treatment. Pursuing the idea to improve both performance and rapidity associated with the histopathological analysis of kidney biopsy, with a possible recourse to artificial intelligence-based renal pathology, the present study intends to assess the impact of direct histopathological examination of kidney biopsy with dynamic full-field optical coherence tomography in routine practices for the diagnosis of either acute kidney injury or chronic kidney disease.

Managing patients with renal failure requires an understanding of the molecular mechanisms that lead to its occurrence (i.e. upstream of the disease), its worsening and its persistence (i.e. downstream), while also specifying the risk of worsening renal failure (risk stratification, intolerance to the treatment or complications (infectious, metabolic, cardiovascular, cancer…). Nephrogene 2.0 aims to study these different components of kidney, immune and solid organ transplantation (SOT)-related diseases.
