Active clinical trials for "Kidney Diseases"

The oxidative stress and inflammatory state is known to contribute to the pathogenesis of atherosclerosis, and is predictive of cardiovascular events and mortality rates in the general population and patients with chronic kidney disease (CKD), particularly in patients with end stage renal disease (ESRD) on dialysis therapy 1. Increased oxidative stress and inflammation has been identified in all stages of CKD, ranging from moderate renal insufficiency to ESRD. However, the pathophysiology of increased oxidative stress and inflammation associated with the development of CKD is currently poorly understood. There is also concern about the epidemic of obesity in the United States, as the overall health status of the general population is adversely affected by increasing adiposity. Recent studies indicate a strong relationship between adiposity and incident CKD. Furthermore, the presence of an elevated body mass index (BMI) is an independent predictor for progression to ESRD, even after additional adjustments for baseline blood pressure and the presence or absence of diabetes mellitus. Limited data in the general population show that healthy lifestyle interventions, such as exercise and dietary caloric restriction, either alone or in combination, reduce the inflammatory and oxidative stress burden seen in obese subjects. The impact of healthy lifestyle modifications on inflammation and oxidative stress has not been investigated in the obese CKD population. Based on the foregoing observations, the purpose of this investigation will be to determine whether healthy lifestyle interventions in the form of low-impact aerobic exercise and dietary calorie restriction in obese subjects (BMI ≥ 30kg/m2) with moderate to severe (Stage III-IV) CKD [estimated glomerular filtration rate (GFR) 20-59 ml/min] will improve oxidative stress, inflammation, insulin resistance, adipocytokines, endothelial dysfunction, and quality of life.

To evaluate the survival benefit associated with Zemplar therapy as compared to Calcijex for the treatment of secondary hyperparathyroidism in subjects with Stage V chronic kidney disease on hemodialysis as measured by time to death.

This study will analyze the germline and somatic mutations underlying the development of ADPKD in order to better understand the genetic mechanism responsible for the cystic transformation. Once identified, these mutations could help us understand better the mechanism leading to the development of this disease and may explain at least in part the phenotypic variability.

16 individuals with hemodialysis-dependent end stage kidney disease will receive 16 days of a potassium-containing salt-substitute and 16 days of standard table salt in random order. There will be a 19 day wash out period between the salt-substitute and table salt periods. Potassium concentration will be measured bi-weekly prior to HD each week during intervention. The primary endpoint will be the change in potassium from baseline. Additional measurements will include assessment of dietary intake, ambulatory blood pressure, occurrence of peri-dialytic symptoms, and per-dialytic vital signs.

Normal-protein and low-AGE through raw or rare proteins diet versus normal-protein and high-AGE diet in stage IIIa-b renal failure patients

Chronic kidney disease (CKD) is a life threatening condition with high risk of pre-term death and need for dialysis. It is defined as kidney damage that has continued for more than 3 months as characterized by structural or functional abnormalities of the kidney, with or without decreased glomerular filtration rate (GFR). It is also defined as GFR < 60mL/min/1.73 m2 for more than 3 months, with or without structural kidney damage. The PCT level in healthy individual without infection is below the limit of detection (0.01 ng/mL), and it is significantly elevated under the stimulation of pathogens. However, due to the pre-existing endogenous inflammation that occurs in CKD patients and the impaired kidney clearance, the reference range that applies to the general population may not be appropriate for diagnosing infections in CKD patients. More recently, debate has continued regarding whether the PCT level is increased in CKD patients without infection, and the optimal reference for CKD patients remains undetermined

The purpose of the TiME Trial is to determine whether dialysis facility implementation of a minimum hemodialysis session duration of 4.25 hours (versus usual care) for patients with end-stage renal disease initiating treatment with thrice weekly maintenance hemodialysis has benefits on mortality, hospitalizations and health-related quality of life. The trial also aims to demonstrate the capacity to conduct a large, pragmatic clinical trial in partnership with two large dialysis provider organizations.

Primary sarcopenia is used to describe aging and progressed with the physiologic decline. Secondary sarcopenia is associated many chronic disease, including acquired immune deficiency syndrome, cancer, chronic heart failure, chronic lung disease, liver cirrhosis, chronic kidney disease and rheumatoid arthritis. In the past, nutrition status is evaluated by body mass index, mid-upper -arm circumference and serum albumin. Bioelectrical impedance analysis is also a common method to measured body composition, but bioelectrical impedance analysis will be affected by tissue edema and ascites. In contrast, cross-section imaging, such as computed tomography and magnetic resonance can analyzed abdominal muscle and fat accurately. Since computed tomography and magnetic resonance imaging can evaluate the severity of polycystic liver and kidney disease. Investigators can use cross section imaging at 3rd lumber level to separate skeletal muscle and fat tissue. Previous studies showed the quantity and quality of abdominal muscle are important prognostic factor after liver transplantation. Besides, chronic kidney disease and receiving renal placement therapy lead protein catabolism and make patients with end stage renal disease have sarcopenia. Finally, patients with polycystic liver and kidney disease have organomegaly, which causes abdominal distention and poor appetite. Therefore, the aim of this study is to observe the association between skeletal muscle mass and the severity of disease and to study whether change in hepatic and renal volumes is associated with change in muscle mass.

HDQ 200 is an interventional multicenter study. This is a before-and-after design in which the patient is his own control. The main objective of the study is to determine the percentage of success of a procedure of daily hemodialysis at low dialysate flow. All patients treated with conventional hemodialysis, for at least 3 months and clinically stable, can be included in the study. Their 3 months data prior to inclusion is collected retrospectively. These 3 months of conventional hemodialysis are the reference period. Patients are then treated with daily hemodialysis at low dialysate flow for 3 months. During this 3 months period, the same data as during the period of conventional hemodialysis are collected prospectively.

The objective of this study is to establish that the MB-102 transdermal fluorescence-measured Glomerular Filtration Rate (GFR) using the MediBeacon® Measurement System with the Transdermal Glomerular Filtration Rate (TGFR) reusable sensor with disposable adhesive ring is comparable to the plasma-measured MB-102 GFR in normal and compromised renal function participants with different skin color types.
