Filter by:The purpose of this study is to examine the effect of mitochondria derived oxidative stress on vascular function in patients with moderate to severe Chronic Kidney Disease.
Dietary management of CKD patients proved important to postpone dialysis. Long-term compliance to protein-restricted diets was discussed. Psychological aspects involved in certain dietary behaviour have never been studied.
The purpose of this study is to learn more about how to identify signs of early chronic kidney diseases in children who were born prematurely with low birth weight (less than 3 ½ pounds). Researchers plan to compare the kidney function in children who experienced acute kidney injury (AKI) in the Neonatal Intensive Care Unit (NICU) with those who did not experience it. Evidence from several studies and our experience at UVA show that older children who experienced AKI while in the Pediatric Intensive Care Unit (PICU) have increased risk of developing early chronic kidney disease, and they also show early changes in the urine and blood that is consistent with early chronic kidney disease. In this study, the investigators hope to determine if any of these changes can be detected in early childhood, and if so, at what age we can start detecting these changes.
Cardiovascular disease is the major cause of morbidity and death in patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD). The mechanisms linking impaired renal function and increased risk for cardiovascular diseases, however, remain elusive. Long non-coding RNAs (lncRNAs) is a heterogeneous group of non-coding transcripts longer than 200 nucleotides. While the roles of lncRNAs in human diseases including cancer and neurodegenerative disorders are beginning to emerge, it remains unclear how lncRNA regulation contributes to cardiovascular complications in patients with renal dysfunction. In this proposal, the investigators seek to apply next-generation sequencing technology to investigate circulating lncRNA expression in control subjects and in patients with CKD and ESRD. The investigators will test the hypothesis that circulating lncRNA expression signature can reflect the underlying kidney disease states in patients with CKD and ESRD. A gene co-expression network analysis will be conducted to identify lncRNAs that are functionally involved in the pathogenesis of CKD and ESRD. Next, the investigators will identify circulating lncRNAs that are indicative of cardiovascular dysfunction in ESRD patients. Finally, the investigators propose to test the hypothesis that circulating lncRNAs can be novel prognostic biomarkers to predict cardiovascular outcomes and renal function progression in CKD patients. The results from these experiments will lead to better understanding of how circulating lncRNAs contribute to uremic cardiovascular complications and renal function progression.
Background： The prevalence of chronic kidney disease (CKD) is high in Taiwan. Though there are many factors that may affect the measurement of serum creatinine, it is a well-accepted marker for renal function assessment. The creatinine clearance (ClCr) estimated by Cockcroft-Gault is commonly used as a reference for dosage adjustment; while the estimated glomerular filtration rate (eGFR) by Modification of Diet in Renal Disease (MDRD) is used in CKD staging. ClCr and eGFR not only have different units, but the results of estimation from the two varied among races and individuals. Since 2010, US Food and Drug Administration required both the influences of ClCr and eGFR on the pharmacokinetics of a drug in renal insufficient patients during pharmacokinetic studies. Because most drugs are excreted through kidney, an understanding on the relationship between ClCr and eGFR is important to dose safely and effectively. Furthermore, identifying the factors that may influence the difference between ClCr and eGFR can provide in-depth consideration during clinical renal function assessment. Purpose： The purpose of this study is to analyze the correlation between different ClCr and eGFR equations in order to provide better renal dose. We also want to find the factors that may cause the differences between them. Methods： This study will conduct literature review to understand study population during the development of different ClCr and eGFR equations, as well as their scope of application. National Taiwan University Hospital electronic patient database will be used to analyze the correlation between ClCr and eGFR and to identify factors that may influence the difference between ClCr and eGFR. The data from patients who have completed 12-hr or 24-hr urine collection with calculated renal function will be used to verify the applicability of these equations (including a ClCr equation developed by our institute) in Taiwanese. Pharmacokinetic principles will be used to analyze the appropriate unit to be used for renal function while dosing a patient.
The purpose of this research study is to determine whether two different types of forearm exercise, performed before fistula creation surgery, can improve surgery success and fistula maturation.
The accumulation of p-cresol, a product of the metabolism of aromatic aminoacid operated by resident intestinal bacteria increases the cardiovascular risk of chronic kidney disease (CKD) patients. Therefore, therapeutic strategies to reduce plasma p-cresol levels are highly demanded. It has been reported that the phosphate binder sevelamer sequesters p-cresol in vitro, while in vivo studies on dialysis patients showed controversial results. Aim of our study was to evaluate the effect of sevelamer on p-cresol levels in CKD patients.
Aldosterone blockade is useful in preserving residual renal function in patients on PD.The long term efficacy of dual blockade of the RAAS is better than monotherapy.
The purpose of this study is to establish whether a short treatment with the synbiotic combination Probinul neutro® may decrease the plasma concentration of the uremic toxin p-cresol in patients bearing a kidney allograft. The effect of this treatment on plasma levels of immunosuppressant drugs will be evaluated as well.
Patients with chronic renal insufficiency usually develop secondary osteoporosis or bone loss, which is called renal osteodystrophy. Most of the previous studies focused on bone metabolism of patients in late stage of chronic renal insufficiency, especially those with chronic dialysis. In this study, bone metabolism of patients in different stages of chronic renal insufficiency will be observed to reveal the mechanism of development of renal osteodystrophy and provide clues for early intervention on renal osteodystrophy.
