Active clinical trials for "Kidney Failure, Chronic"

The introduction of unfractionated heparin (UFH), which prevents clotting of the extracorporal circuit, was one of the key advances that led to the rapid development and expansion of hemodialysis services. However, anticoagulation during hemodialysis of the patient at high risk for bleeding remains a frequently encountered problem in both inpatient and outpatient dialysis practice. Streamline bloodlines are designed to eliminate blood-air contact. This is thought to help reduce heparin use and decrease clotting rates. The goal of this study was to prospectively examine impact of the Streamline airless blood tubing set, in an inpatient setting, on dialysis circuit clotting rates, anticoagulation use, and dialysis efficiency.

This study investigates the relationship between autonomic dysfunction and chronic inflammation in hemodialysis patients.

The MBD-5D is a prospective observational study with a case-cohort and a cohort design. Eligible patients are receiving hemodialysis and have secondary hyperparathyroidism. The study's three goals are (1) to record the patients' characteristics, and variation in the patterns of their treatment; (2) to analyze factors associated with variation in those medical practice patterns; and (3) to identify practice patterns and other factors that affect hospitalization, mortality, and other patient-level outcomes.

Post market observational survey of a vascular access device for access-challenged patients. Data collection efforts focused on patient medical and access history and implant procedure results.

Anemia is frequent in patients with heart failure. Few studies have clearly addressed the causes of anemia in patients with HF. The purpose of this study is to evaluate differences in blood concentrations of various substances related to inflammation, oxidative stress, renal function and other processes between individuals with 1) heart failure and anemia, 2) heart failure without anemia and 3) patients with kidney disease without systolic heart failure. This study will help to better understand the reasons why some people with heart failure have anemia.

The investigators want to test the hypothesis that patients with chronic renal disease have a poorer ability to preserve water after being thirsty and a poorer ability to excrete water after a load of fluid. They presume that these abilities become poorer when renal insufficiency progresses. The investigators further hypothesize that patients with hypertension also have a decreased ability to concentrate and dilute urine.

Patients with end-stage kidney disease are treated with dialysis to increase their life expectancy as well as their quality of life (QoL). Scientific researchers are currently still looking for markers to evaluate dialysis in an objective way. It has been proven before that the currently clinically used parameters (like the dialysis adequacy parameter Kt/V) are not appropriate enough to estimate dialysis dose. The current project aims at identifying potential (predicting) biomarkers based on functional capacity, nutritional status and/or QoL.

The aim of the study is to compare intradialytic plasma kinetics of amino acids after administration per os of Renoral or intravenous administration of amino acids in patients with end-stage renal disease treated with hemodialysis maintenance.

In patients with non-dialysis-dependent end stage kidney disease (ESKD) the common transition of care to renal replacement therapy is dialysis. Each year over 70 000 Chinese transition from non-dialysis-dependent ESKD to dialysis. Whereas dialysis therapy is intended to be life-sustaining, ESKD patients have a 10-fold or higher risk of death compared with the general population. Mortality rates are even higher upon transition and in the first year, especially in the first 3 to 6 months following the transition to dialysis, yet it remains unknown which is the contributing cause of this high death rate. Hence, there is an urgent need to examine the emerging field of Transition of Care in ESKD. We suggest the term "peridialysis period" for this transition period for ESKD patients, so that the transition of care from non-dialysis-dependent ESKD to dialysis ESKD can be more pragmatically defined and studied. In the current study, we will investigate the mortality and its risk factors of ESKD patients during peridialysis period, and improve the survival rate and quality of life of peridialysis ESKD patients by intervening the risk factors.

Every patient included in the study will undergo 1 conventional hemodialysis treatment, ie 1 study visit. During the conventional hemodialysis treatment lasting 4 hours, 2 blood samples will be taken at different time points (5 minutes after dialysis start and 240 minutes after dialysis = at the end of the dialysis session) to evaluate coagulation activation (TAT, PF1+2). Hemodialysis session parameters (arterial and venous pressure, TMP, OCM, BVM and prefilter pressure) will be noted at different time points (T5, T30, T60, T120, T180, T240). After discontinuation of the dialysis session, total cell volume will be measured using the Renatron II system® and the number of open fibers will be determined using micro-CT scanning.
