Active clinical trials for "Kidney Diseases"

This study has two major purposes: To test developed multiple anatomic and functional MRI methods; To evaluate the potentials of these MRI methods in the diagnosis, prognosis, and monitoring of the progression of renal dysfunction. These purposes will be achieved by performing pilot studies with cohorts of patients.

Patients with chronic kidney disease (CKD) experience fatigue and exercise intolerance. Increased oxidative stress in CKD may be a contributing factor. The role of impaired muscle blood flow regulation has not been fully explored. The investigators hypothesize that functional sympatholysis is exaggerated in CKD and this is associated with increased oxidative stress. The investigators also hypothesize that exercise training will improve functional sympatholysis and oxidative stress

Cardiovascular diseases are the leading cause of mortality in patients with end stage renal disease (ESRD). They often have myocardial ischemia (a major predictor of mortality) on non invasive testing (Stress echocardiography and/or myocardial perfusion scintigraphy) but the incidence of significant coronary stenosis (>70%) is low. The goal of this observational study is to evaluate the incidence and clinical outcomes of proven myocardial microvascular disease in patients with end stage renal disease scheduled or not for kidney transplantation. These patients routinely undergo non invasive detection of myocardial ischemia. Patient included in the study will be followed up for 2 years for major cardiovascular events. Patients with detected myocardial ischemia during non invasive testing are being explored by coronary angiography. During coronary angiography additional detection of myocardial microvascular disease is being performed by simultaneous measurement of Fractional Flow Reserve (FFR) and Coronary Flow Reserve (CFR) followed by calculation of the index of microcirculatory resistance (IMR). Comparison of cardiovascular outcomes between patients with and without myocardial ischemia and patients with and without myocardial microvascular disease will be performed.

This trial will evaluate whether treatment with CRMD001 (unique formulations of the iron chelator, Deferiprone) will reduce morbidity and mortality in subjects with Chronic Kidney Disease (CKD) and additional risk factors. Adult subjects with moderate to severe CKD who are undergoing diagnostic or interventional coronary angiography will be randomized to either placebo or CRMD001 and followed for 90 days. Subjects will receive 8 days of randomized therapy starting 1-3 hours prior to angiography. The primary endpoint of the trial will be the difference in a composite of specified renal and cardiovascular clinical events occurring through Day 90.

This is an observational longitudinal study which will collect routine demographic, laboratory and clinical parameters of patients with chronic kidney disease (CKD) in the Silesian and Warmia and Mazury Regions (Poland) aimed at predicting incident cardiovascular disease and cardiovascular and renal events using machine learning and artificial intelligence approaches.

The goal of this clinical trial is to understand if and how an animal-assisted intervention [AAI] using therapy dogs can support hemodialysis [HD] patients' treatment adherence and enhance their well-being. The main objectives are: Objective 1: Determine if the AAI impacts patients' HD treatment adherence (primary outcome is number of unplanned missed treatments no due to hospitalization). Objective 2: Evaluate if the AAI impacts patients' psychosocial well-being (secondary outcomes are stress, pain, mood, QOL). Objective 3: Examine potential mechanistic biomarkers that underpin human-animal bonding (hormones tied to stress and bonding). (exploratory aim) Objective 4: Understand patients' subjective experiences of the AAI. Participants will be asked to engage in several research tasks, including: assessments therapy dog visits monthly blood draws focus group Researchers will compare how the treatment group (those who receive 2 dogs visits per week) and the control group (those who receive 0 dog visits per week) to see if the AAI impacts treatment adherence and psychosocial well-being.

Phase 2, multi-center, open label extension study to evaluate 2 dose regimens of fostamatinib in approximately 25 subjects. The study will consist of 11 visits over 15 months.

The general objective of this open, pilot study is to characterize biological parameters related to acute kidney injury among patients undergoing a programmed coronarography with injection of contrast material. The study focuses on two main factors that may influence acute kidney injury: (1) sodium chloride hydration strategy versus sodium bicarbonate hydration strategy and (2) presence of oral L-carnitine treatment versus absence of oral L-carnitine treatment. We will also test for a potential interaction between these two factors.

In Tunisia, high blood pressure (HTN) is a public health problem whose prevalence varies from 28.7% to 34.7%. Hypertension can be both, cause and consequence of chronic kidney disease, and its prevalence is quite high in this population. It is both a risk factor for mortality and cardiovascular morbidity, but also a major cause of terminal chronic kidney disease becoming an additional public health concern. Detecting and diagnosing chronic kidney in all hypertensives at an early stage remains a global public health challenge. A well-conducted treatment makes it possible to reach the blood pressure objective but also to reduce the risk of occurrence of a cardiovascular event and to slow the progression of chronic kidney disease. In Tunisia, few data exists concerning the prevalence of chronic kidney disease in hypertensive subjects, thus limiting the development and elaboration of preventive measures. A national survey will thus be conducted by the "Kidney and Metabolic Diseases" Working Group under the aegis of the Tunisian Society of Nephrology, Dialysis and Kidney Transplantation. The main objective is to estimate the prevalence of chronic kidney disease in hypertensive tunisian patients.

This study is intended to investigate the usefulness of estimated glomerular filtration rate (eGFR) slopes derived from retrospective routine clinical practice data, compare those retrospective slopes with those generated in a prospective fashion and successively identify rapidly progressing chronic kidney disease (CKD) patients.
