Filter by:Use of Paricalcitol in stage Vd Chronic Kidney Disease patients, over the effect of inflammatory and oxidative stress parameters.
The purpose of this study is to estimate the differences between albuminuria values determined as Urine Albumin-to-Creatinine Ratio (UACR)(log transformed) from baseline to last observation caused by paricalcitol between the group of control and group of treatment.
The objective of this study is to assess the safety and tolerability of colestilan (MCI-196) in paediatric subjects (aged 2 years to <18 years) with CKD stages 3b to 5, diagnosed with hyperphosphataemia, who are not on dialysis.
The Primary Objectives of this study are to assess the long-term efficacy of treatment with colestilan (MCI-196) (including combination therapy) and to assess the long-term safety of treatment with colestilan (MCI-196) (including combination therapy).
The Primary Objective of this study is to determine the initial starting doses of colestilan (MCI-196) in paediatric subjects with Chronic Kidney Disease Stage 5 on Dialysis and with Hyperphosphataemia.
Estimation of hydration state in dialysis patients is a major challenge in clinical practice. Although many methods have been studied, none have been established yet for clinical routine practice. The investigators have developed a method, using segmental and calf bioimpedance spectroscopy (cBIS) techniques to measure body hydration. The device we used based on the FDA-approved Hydra 4200 (Xitron Technologies, San Diego, CA). The Hydra 4200 was initially developed to measure whole body and segmental body fluid volumes but Hydra is approved only for measuring healthy subjects. The cBIS monitors hydration state by continuously measuring change in resistance and resistivity in the calf during hemodialysis (HD) or it can be used for simple measurement before, during and after dialysis. Preliminary results in clinical studies have shown that optimal hydration state of HD patients may be determined by the calf method. This study aims to compare the Hydra 4200 to two other devices: the FDA approved ZOE (100 kHz) Fluid Status Monitor (Noninvasive Medical Technologies, Inc, Las Vegas) and a modified version ZOE 5 kHz. The modified ZOE monitor (ZOE (5 kHz)) delivers frequency of 5 kHz and 0.8 mA current instead of 100 kHz and 2 mA. The subjects of this study include a group of hemodialysis patients and a group of healthy controls. The healthy controls are used to identify a normal range within the healthy population for each method. Each hemodialysis patient will be studied twice in different hydration state. The study will not change the procedure of the patient's dialysis treatment. Since all devices are based on noninvasive bioimpedance technique, this study has minimal risk.
Objective: To show that the frequency of aldosterone breakthrough is lower when RAS blockers are given at bedtime compared to on awaking, and to analyze the determinants and consequences of aldosterone breakthrough. Duration of the study: Inclusion 2 years, follow-up one year, total 3 years Design: prospective, multicenter, randomized, controlled, open label, two parallel groups. Main selection criteria: Inclusion criteria - Chronic kidney disease stage 3 to 4, - ACEI (captopril, enalapril, or ramipril), and/or ARB (losartan, valsartan, or irbesartan) on awaking for at least three months, - History of hypertension or proteinuria > 0,5 g/24h or g/g créatininurie. Exclusion criteria - Office blood pressure ≥ 160/100 mmHg, - Anti-aldosterone (spironolactone, eplerenone) or potassium sparing diuretics (modamide, amiloride), or direct renin inhibitor. Evaluation criteria: Primary: Serum aldosterone levels at one year. Secondary: - Serum aldosterone/renin ratio, - 24h urine aldosterone, - Significant aldosterone breakthrough defined by a >10% increase of serum aldosterone levels over baseline values, - Aldosterone breakthrough defined by an increase of serum aldosterone levels over baseline values, - HbA1c, - Urinary albumin/creatinine ratio (UACR) on spot morning urine samples, - Systolic home blood pressure (SBP), - Estimated glomerular filtration rate (eGFR) using the MDRD equation.
The purpose of this study is (1) to determine whether a 12-month trial of patients from underserved communities with clinically significant gum disease and kidney disease randomly assigned to intensive gum disease treatment or delayed treatment is feasible and (2) to determine the variability of various tests of kidney function and inflammation in response to intensive gum disease treatment.
The study's purpose is to address the challenges of providing stage-appropriate chronic kidney disease (CKD) education and care by developing innovative programs using a CKD Patient Navigator system and an EHR (electronic health record)-based enhanced electronic communication system specific for a CKD patient and her/his physicians/caregivers. The investigators plan a randomized controlled trial of these innovations to examine the utility and effectiveness of these special interventions. The investigators' CKD registry aids in identifying patients for recruitment for the randomized control trial. Patients are randomized into one of four groups. The four groups are: 1) the control group using MyChart; 2) an enhanced personal health record (PHR) included in MyChart consisting of 35 websites chosen to disseminate CKD stage-specific goals of care and CKD education; 3) the patient navigator, a lay professional trained in the specifics of chronic kidney disease navigation with a focus on the needs of their patients based on the National Kidney Foundation Disease Outcomes Quality Initiative; 4) the patient navigator combined with the enhanced MyChart. The investigators hypothesize that a CKD Patient Navigator program will develop a more prepared, proactive patient-caregiver team than usual care; the enhanced PHR will produce a more informed, engaged patient than usual care; the CKD Patient Navigator arm and enhanced PHR will demonstrate a slower rate of decline in eGFR (glomerular filtration rate) than usual care. The results of this study will lay the foundation for a larger multi-center national clinical trial that will build upon the feasibility and knowledge gained from this planning grant.
The purpose of this research study is to study the effects of paricalcitol on endothelial function and inflammation, cardiovascular risk factors which are associated with patient populations that have Type 2 diabetes and Stage 3 and 4 Chronic Kidney Disease (CKD). Hypothesis 1: The state of CKD is associated with oxidative stress and inflammation and impaired post ischemic endothelium dependent flow mediated vasodilation which may contribute to atherogenesis. Hypothesis 2: The administration of paracalcitol to patients with CKD will suppress oxidative stress and inflammation and improve endothelial function and thus contribute to an anti-atherogenic action.
