NCT ID: NCT06238310 Recruiting - Acute Kidney Injury Clinical Trials

Comparison of Two Different External Clearance Markers - Mannitol and Iohexol for Measuring Glomerular Filtration Rate

GFR
Start date: August 1, 2023
Phase: N/A
Study type: Interventional

GFR is the best parameter of the real kidney function. Measurements, however are time-consuming and have limited capacity. Patients treated in the intensive care units often have more than one organ-insufficiency and acute kidney injury (AKI) has an incidence of up to 70 %. GFR changes dynamically and this is one of the reasons why GFR-measurements have limited indications on the ICU. Retention of medicines or their active metabolites, however can lead to side effects, toxicity and or prolonged ICU-stay. Moreover, patients with allergy to actually standard marker, contrast material iohexol, or gravid patients are not candidate for measuring GFR with iohexol. In this prospective clinical trial two exogen marker substances will be compared, mannitol as a new marker and iohexol as a standard marker for measuring glomerular filtration rate (GFR). Patients in the intensive care units (ICU) and an outpatient group with stable chronic kidney disease (CKD) are included. The main question is, how reliable mannitol-GFR is compared to iohexol-GFR in a wide range of kidney insufficiency. GFR measurements are performed with a bolus injection technique. Patients get mannitol and iohexol bolus at time zero and blood samples are taken three times according to local protocols for iohexol clearance measurements.

NCT ID: NCT04334707 Recruiting - Clinical trials for Chronic Kidney Diseases

Kidney Precision Medicine Project

KPMP
Start date: September 1, 2019
Phase:
Study type: Observational

Acute kidney injury (AKI) and chronic kidney disease (CKD) impose a significant global health burden. Yet, no effective therapies currently exist for AKI, and only a few are available for CKD. Despite significant effort from industry and academia, development of pharmacologic therapies for AKI and CKD has been hampered by: Non-predictive animal models The inability to identify and prioritize human targets The limited availability of human kidney biopsy tissue A poor understanding of AKI and CKD heterogeneity Historically, AKI and CKD have been described as single, uniform diseases. However, growing consensus suggests that different disease pathways lead to different subgroups of AKI and CKD (AKIs and CKDs). Access to human kidney biopsy tissue is a critical first step to define disease heterogeneity and determine the precise molecular pathways that will facilitate identification of specific drug targets and ultimately enable individualized care for people with AKI and CKD. A number of research centers across the United States are collaborating to bring state-of-the-art technologies together to: - Ethically obtain and evaluate kidney biopsies from participants with AKI or CKD - Define disease subgroups - Create a kidney tissue atlas - Identify critical cells, pathways, and targets for novel therapies The KPMP is made up of three distinct, but highly interactive, activity groups: - Recruitment Sites: The recruitment sites (RS) are responsible for recruiting participants with AKI or CKD into the longitudinal study and performing the kidney biopsy. - Tissue Interrogation Sites: The tissue interrogation sites (TIS) are responsible for developing and using innovative technologies to analyze the biopsy tissue. - Central Hub: The central hub is responsible for aggregating, analyzing, and visualizing the generated data and providing scientific, infrastructure, and administrative support for the KPMP consortium.

Start date: August 1, 2018
Phase:

NCT ID: NCT03319888 Recruiting - Sleep Apnea Clinical Trials

Effect of CPAP in the Worsening of Renal Function in Early Stages of Chronic Kidney Disease (CKD)

Renas
Start date: November 20, 2017
Phase: N/A
Study type: Interventional

Objectives: Evaluate the effect of CPAP to reduce the progression of chronic kidney disease or CKD (the decline of glomerular filtration rate is ≥ 30%) in patients with early-stage renal disease and sleep apnea syndrome (OSAS). Other objectives are; determine the prevalence of OSAS in patients with early-stage renal disease and evaluate the changes in inflamatories markers and endothelial damage, the state of KDIGO, cardiovascular events, mortality and cost-effectiveness analysis in CPAP group versus non-CPAP group patients. Methods: A prospective, multicentric, randomized and controlled study will be carried out for 3 years. Early-stage renal disease (G1-3 KDIGO) and OSAS patients will be included. The investigators will make a respiratory polygraphy to determinate OSAS (AHI ≥15/h) and after that, the investigators randomized patients in 2 groups; CPAP group and control group (non-CPAP treatment). Patients with AHI <15/h (non-OSAS) will be the reference group and the half of these patients, randomly chosen, will be followed up at the end of the follow up. Statistic analysis: the investigators will analyze the differences in glomerular filtration rate before and after the treatment, comparing the percentage of patients with CKD progression for both groups. The investigators will use the chi square test with raw data and adjusted for confounding variables using intention to treat analysis with imputation of missing values.

NCT ID: NCT01977430 Recruiting - Clinical trials for Chronic Kidney Insufficiency

Clinical Trial to Compare Effectiveness of Diuretics in Hemodialysis Patients With Residual Renal Function

RRF
Start date: November 2013
Phase: Phase 4
Study type: Interventional

Introduction: Chronic kidney disease is characterized by a progressive deterioration of renal function. At the end of the progression, when complications occur (overhydration, electrolyte imbalances or retention of uremic toxins), a percentage of patients requiring renal replacement therapy (haemodialysis). When starting the haemodialysis, the patient holds the residual renal function (RRF) which is lost over time. To preserve the RRF, the patient is treated with diuretics loops and / or thiazide diuretics. The effect of this treatment is lost when renal function worsens. In this context, there are few studies that explore the use and effectiveness of diuretics in patients on haemodialysis 2. Objectives and Hypothesis: Hypothesis: The treatment with furosemide and hydrochlorothiazide in haemodialysis patients with RRF could: - To decrease in weight gain between haemodialysis sessions. - To increase urine volume. - To decrease the ultrafiltration in haemodialysis sessions ( the long interdialytic interval) Main Objective:To asses the effect of combined hydrochlorothiazide-furosemide therapy on gain weight between haemodialysis sessions in patients with RRF Secondary Objective: To asses the effect of combined hydrochlorothiazide-furosemide therapy on dialytic, clinical and analytical variables and use of the antihypertensive treatment 3. Methodology: Randomized open clinical trial to compare the effectiveness of the administration of diuretics in haemodialysis patients with residual renal function in single centre. The population of study are patients with chronic renal disease in haemodialysis therapy that they preserve residual renal function ( more 200ml daily of urine). It will be a simple randomization, to asses the effect of combined hydrochlorothiazide-furosemide therapy After a of 15 days washout without diuretic treatment, patients will be randomized to receive or not receive combined diuretic treatment for 1 month. After a 1 month washout , the patients will be receive or not the treatment according to cross over trial.
