Filter by:As iodinate contrast media (CM) has been widely used in current medical practice, contrast induced acute kidney injury (CI-AKI) has been an important issue. Previously, many guidelines suggested prophylaxis protocol using 0.9% saline when CM is administrated to high risk patients. However, recent studies showed that 0.9% saline might induce metabolic acidosis due to its supra-physiologic chloride component, and therefore renal vasoconstriction. In spite of protective effect by volume expansion with saline infusion, this renal vasoconstriction might have conflicting effect on renal function, as hypoxic injury is suspected to be the main cause of CI-AKI. In contrast to 0.9% saline, balanced salt solution has physiologic level of chloride and neutral pH. Also, recent studies proved preventive effect of balanced salt solution for AKI in several clinical settings. Hence, the investigators planned a prospective randomized controlled trial comparing 0.9% saline and balanced salt solution to prevent CI-AKI.
Heart failure (HF) is an epidemic and is a major burden on the US healthcare system. The most common cardiovascular endpoint is HF. Thus, novel interventions to prevent HF in chronic kidney disease (CKD) are highly desirable. This study will assess: the variability in the response to isosorbide mononitrate (ISMN) therapy; the degree of change in central hemodynamics and cardiac endpoints through analysis of changes in left ventricle (LV) mass, diffuse myocardial fibrosis, and myocardial systolic and diastolic function.
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 evaluate the effectiveness of the study drug IdeS in patients who are on the waiting list for kidney transplant and have previously undergone desensitization unsuccessfully or in whom effective desensitization will be highly unlikely. At study entry, the patients will have an available deceased or live donor with a positive crossmatch test. The study will assess IdeS efficacy and safety in removing Donor Specific Antibodies (DSAs) and thereby convert a positive crossmatch test to negative.
The objective of this study will be to evaluate the effects of neuromuscular electrical stimulation of high and low frequency and intensity, performed during hemodialysis (HD), on peripheral muscle strength, exercise capacity and muscle change and inflammation markers in patients with chronic kidney disease (CKD).
The objectives of the Healthy.io Method Comparison and User Performance Study are: 1. To evaluate the performance of Dip.io Device in comparison to the ACON U500 Mission® U500 Urine Analyzer. 2. To evaluate the user performance of Dip.io Device under actual use conditions (home environment) based on a user questionnaire and rating scale.
Preeclampsia (Pre-E) is a hypertensive disease of pregnancy with multi-system involvement that usually occurs in the second half of pregnancy. Pre-E occurs in 5% to 7% of U.S. pregnancies, and is the third-leading cause of U.S. maternal death. Improvements to the current diagnostic paradigm have been evaluated. However, no stand-alone diagnostic method has emerged that more accurately identifies women at risk for preeclampsia, warranting improvements in diagnosing Pre-E. This sample collection study will obtain serum and urine samples from pregnant women who present with clinical signs, symptoms, or conditions contributing to the suspicion of Pre-E. Samples will be used to evaluate and validate the performance of an assay intended to aid in assessing the risk of Pre-E.
The primary objective of this study is to evaluate the potential effect of renal impairment on the systemic pharmacokinetics of acute Intranasal RX0041-002. The secondary objective is to evaluate the safety and tolerability of acute Intranasal RX0041-002 in subjects with normal renal function and severe renal impairment.
This study was a pilot, safety, and pharmacokinetic study of MB-102 versus iohexol and the use of the non-invasive optical renal function monitor (ORFM) device in normal and compromised renal function participants with different skin color types.
Thrombotic dysfunction is a common complication of tunneled cuffed catheters (TCC) leading to inadequate dialysis dose, need to catheter replacement with as consequence progressive exclusion of vascular sites. Thrombolytic agent can be used as therapeutic locking solution to dissolve the clotting formed in of around the catheter lumen. There are few studies on the optimal approach of TCC-related thrombosis with thrombolytic containing locking solution (dose, number of administrations, timing of administration - intra or interdialytic use). The primary objective of this retrospective study was to compare the efficacy of inter versus intradialytic Urokinase containing locking solution on restoration of the TCC blood flow. The investigators also assess the question of multiple administrations of Urokinase are more efficient than one single administration
