Active clinical trials for "Kidney Diseases"

Background: Patient with stage 3 or 4 chronic kidney disease (CKD) usually has normal level of serum phosphate, due to increased serum fibroblast growth factor-23 (FGF23) level that resulted in increased phosphate urine excretion. On the other hand, serum FGF23 elevation was related to CKD progression, vascular calcification, cardiomegaly, and mortality. This double blind, randomized controlled trial study was conducted to evaluate effectiveness and safety of calcium carbonate administration in stage 3 or 4 CKD patients with normophosphatemia. Hypothesis: Calcium carbonate administration is effective and safe in chronic kidney disease (CKD) with normophosphatemia.

The investigators plan a prospective cross-sectional study of pediatric and adult healthy volunteers and patients with chronic kidney disease that will correlate a variety of quantitative MRI biomarkers with severity of renal insufficiency and available histopathology. Over 3 years, the investigators will recruit approximately 20 healthy volunteers, 20 patients with chronic kidney disease (CKD) Stage 2-5, and 20 patients with renal transplant kidneys. The investigators also plan to assess the effect of inflammation on the quantitative MRI biomarkers by recruiting approximately 20 additional patients with active lupus nephritis.

This study is to assess the effect of 48 weeks administration of Renamezin capsule on prevention of sarcopenia in pre-dialysis patients with chronic kidney disease.

This study is designed to compare the bioavailability of the test Product(CE-Iohexol Injection) and the reference product Iohexol Injection (Omnipaque™) following intravenous injection in normal healthy volunteers. The secondary objective is to assess the safety and tolerability of the treatments administered. Captisol® is present to improve stability and to potentially reduce the risk of contrast-induced acute kidney injury(CI-AKI) associated with iohexol administration.

In spite of conventional immunosuppression with lymphocyte-depleting induction followed by tacrolimus- and mycophenolate-based regimens, African American (AA) renal transplant recipients experience higher rates of acute rejection (AR), donor specific antibodies (DSA), and graft failure. Envarsus Extended-Release (XR)® (ENV) is a novel extended-release formulation of tacrolimus with a favorable pharmacokinetic profile, even in the setting of CYP3A5*1 allele (rapid metabolizers). The investigator will evaluate the safety and efficacy of early dose escalation with ENV in AA recipients. The study hypothesis is that higher tacrolimus target concentrations may be achieved without typical dose-limiting toxicities, and this may ultimately result in lower incidence of early AR, DSA, and graft loss.

The primary objective of this prospective study is to assess the trend of sugammadex (and its complex with rocuronium) concentration in surgical patients with routine outpatient hemodialysis. Patients with end stage renal disease who are to receive general anesthesia and muscle paralysis will have their paralysis by rocuronium reversed with sugammadex. Patients will then have blood drawn during their next three routine hemodialysis sessions to assess for the plasma concentration of sugammadex or the sugammadex-rocuronium complex over time.

The objective of this unblinded study is to assess the nutritional effects of a 12 weeks administration of the specific enteral nutrition (SEN) RealDiet®Renal pockets, as well as the impact on the patients' quality of life.

Contrast-induced nephropathy (CIN) is a complication of percutaneous coronary angiography that occurs in about 10 to 20% of patients exposed to contrast media. Iodinated contrast is used during coronary angiography to see the coronary arteries. It has been shown that exposure to this agent may cause kidney injury. CIN usually goes away on its own but in some high risk patients it progresses into renal failure. This research study offers a new possible option to prevent CIN. We propose that if intravenous nitroglycerin is given before the procedure it may lower the chances of developing contrast-induced nephropathy.

Aim: Patients with type 2 diabetes mellitus (T2DM) and hemodialysis due to diabetic nephropathy exhibit a high risk for sudden cardiac death (SCD). Preliminary data suggest that beta-blocker treatment may reduce arrhythmias and mortality in this high-risk population. However, no results from large-scale clinical outcome trials with beta-blockers exist in this patient group and a broad, scientifically unapproved use of beta-blocker treatment may not be justified due to potential harmful side-effects such as AV-block or hypotension. In addition, we are lacking identified ECG surrogate parameters for SCD in this high-risk population and on the occurrence of arrhythmias in temporary relationship to hemodialysis sessions. Therefore, the present study will identify surrogate parameters of SCD in hemodialysis patients with T2DM and in an interventional trial investigate the suppressive effect of beta-blockers on these identified ECG markers.

Poor nutritional status as evidenced by low body mass index, low muscle mass or low serum albumin is a strong predictor of morbidity and mortality in dialysis patients. Hypercatabolism induced by inflammation is widely considered the cause of uremic malnutrition even though there is no clear evidence that hemodialysis patients with elevated C-reactive protein (CRP) levels are at greater risk of losing weight or muscle mass. Conversely, there is little data on whether dialysis patients with malnutrition and elevated C-reactive protein levels would gain muscle mass with protein supplementation. The hypothesis is that protein supplementation during dialysis will improve muscle mass, functional status and quality of life in inflamed malnourished hemodialysis patients. Therefore, the objectives of the current proposal are to examine in malnourished (body mass index < 23 kg/m2 or serum creatinine < 8 mg/dL) hemodialysis patients with inflammation (high sensitivity CRP > 3 mg/dL), the effects of protein supplementation on Muscle mass as determined by creatinine kinetics Functional status as assessed by 6 min walk Quality of life as assessed by Short Form -12 survey
