Active clinical trials for "Renal Insufficiency, Chronic"

Prospective, single-center study to evaluate the everlinQ endoAVF System when used to create an endoAVF in hemodialysis patients. This study aims to investigate expansion of the percutaneous venous access location to the superficial system which may provide additional procedural benefit.

This is an observational study in which the health data of people with chronic kidney disease are studied using electronic healthcare records. In observational studies, only observations are made without participants receiving any advice or any changes to healthcare. Chronic kidney disease (CKD) is a condition in which the kidney's ability to work properly gradually decreases over time. This causes a buildup of waste in the body and can lead to loss of kidney function over the long term. CKD is divided into different stages based on how well the kidneys are filtering the blood. CKD is known to increase the risk of developing serious health problems such as serious heart problems, irreversible damage to kidneys requiring either dialysis or a kidney transplant (end stage kidney disease, ESKD), and early death. However, there is limited information available about how often heart problems occur in people with different stages of CKD, and how a history of heart problems might affect future risks for CKD patients. The purpose of this study is to collect more information on how CKD changes over time for people at different CKD stages and how it affects their heart and kidneys. The main information that researchers will collect in this study: changes in kidney function (worsening or improvement). Other information that researchers will collect: patient characteristics for each stage of CKD, the length of time for serious heart-related conditions to occur, the length of time it takes for CKD to progress to kidney failure, the length of time for occurrence of deaths due to any causes, and the length of time it takes for serious heart-related conditions and kidney failure to occur. This study will include CKD patients above 18 years of age. Researchers will review electronic healthcare records to identify CKD patients in two ways: using disease codes for CKD and using lab results which show abnormal kidney function. The data will come from participants' information stored in an electronic healthcare records database called Merative Explorys database Electronic Medical Record (EMR) in the United States of America. The research will cover the period from January 2010 up to December 2019. Researchers will track individual patients' data and will follow them for a maximum of 5 years or until they experience certain events like changes to their CKD stage, kidney failure, serious heart-related conditions, or death. In this study, only available data from routine care is analyzed. No visits or tests are required.

The purpose of this study to test whether n-of-1 trial-guided clinical decision-making improves blood pressure control in hypertensive children with chronic kidney disease (CKD) and end-stage renal disease (ESRD).

The purpose of this study is to determine if patiromer treatment in chronic kidney disease (CKD) subjects receiving spironolactone for the treatment of resistant hypertension will result in more persistent use of spironolactone through prevention of hyperkalemia and lead to improved blood pressure control compared with treatment with spironolactone alone (placebo).

This is a pilot, single-center, randomized trial of 90 subjects to evaluate complication rates and functional status decline in subjects age 65 years and older referred for vascular access placement. Subjects will be randomized to arteriovenous fistula (AVF) (n = 45) versus arteriovenous graft (AVG) (n = 45), placed in a vascular access monitoring protocol, and undergo measurements of functional status including gait speed, grip strength, and self-reported function over 6 months. The primary hypothesis to be tested is that AVF placement will result in a higher proportion of primary access failure as defined by a binary composite primary endpoint of an unsalvageable access or an immature access or a non-functional access measured at 6 months compared to AVG placement. In addition, the study will evaluate whether AVF placement and a greater number of access procedures will result in a greater decline in functional status as measured by the average change over 6 months in gait speed, grip strength, and self-reported function as assessed by the Disabilities in Arm, Shoulder and Hand Survey.

In the last decade, transcatheter aortic valve replacement (TAVR) has become an increasingly utilized alternative procedure for replacing a stenotic aortic valve. This study collects clinical information, DNA, blood and urine samples (throughout procedural hospitalization) in order to investigate the incidence of acute kidney injury (AKI) in patients undergoing TAVR and to identify key clinical and procedural predictors of AKI. This study seeks to identify blood and urine biomarkers that can be used for early detection of AKI around the time of the procedure. The study seeks to assess for novel genetic variants associated with development of AKI after TAVR. Finally the study seeks to assess for novel genetic variants and biomarkers that are associated with adverse cardiovascular events after TAVR and to further explore how these events may inter-relate with acute kidney injury.

The purpose of this study is to ascertain whether Arotinolol Hydrochloride reduces mortality and cardiovascular events in chronic kidney disease stage 5 patients with hypertension.

This trial is designed to determine if the use of a computer algorithm designed to optimize mineral outcomes in dialysis patients increases the number of patients achieving the desired target endpoints for calcium, phosphorus and parathyroid hormone.

The Polyflux HD-C4 (Gambro Renal Products) is a new dialyzer based on the existing Polyflux H membrane and dialyzer technology, but which achieves a performance comparable to Polyflux 210H in a significantly smaller device. The objectives of this study are: To compare and contrast small and large molecule removal by the Polyflux HD-C4 and Polyflux 210H dialyzers under conditions of routine hemodialysis; and, To compare and contrast the ease of use of the Polyflux HD-C4 dialyzer with that of the Polyflux 210H under conditions of routine clinical use for hemodialysis.

This study is being conducted to evaluate sitaxsentan dosing in subjects with chronic kidney disease.
