Active clinical trials for "Renal Insufficiency, Chronic"

There are severe deficiency of database concerning the oral health status in both pre-dialysis and end stage renal disease in Egyptian population. Our aim in the present study is to assess the oral health of the chronic kidney disease patients to increase their awareness and minimize all the possible risk factors, to achieve a proper management for all oral problems.

The national drug safety agency authorizes nominatively the use of sodium thiosulfate in dialysis patients with calciphylaxis. To date, it is the largest global cohort (more 600 patients from 2012 to 2016). We wanted to study retrospectively the fate of these patients at 6 months including mortality. Early use improves effectiveness.

Our study seeks to define the effect of each component of the distal revascularization interval ligation (DRIL) procedure on the in vivo distal blood pressure of patients with ischemic steal, and to determine whether the interval ligation component of the DRIL procedure is necessary or not.

Metformin is the most widely prescribed oral treatment for diabetes, and the only one that showed a survival benefit. Yet, there is no consensus on the optimal dose and withdrawal of metformin in chronic kidney disease (CKD) patients. The aim of the study is to describe the use and side-effects of metformin in CKD patients in routine practice.

Bioimpedance is recently known to be a reliable, reproducible and validated technic allowing determination of hydratation status in patients with chronic kidney disease treated with peritoneal dialysis (PD). Overhydratation attested by bioimpedance is strongly associated with cardio-vascular morbidity and mortality in patients with PD. Overhydratation might concern more than half of patients at PD initiation, though the underlying mechanism remains unknown. High peritoneal permeability (HPP) might concern about a third of patients starting a PD, although only a few datas are published on this condition. HPP at initiation of PD is associated with a decrease in both technical and patient survival and might be responsible of ultrafiltration failure. The underlying mechanisms of HPP at initiation of PD also remains unknown. To our knowledge, the correlation between hydratation status and peritoneal permeability at initiation of peritoneal dialysis remains unknown. Moreover, there is no datas concerning the cinetic evolution of peritoneal permeability; demographic or biologic factors associated with HPP in days and months following PD start. The aim of the present study is to correlate hydratation status (attested by bioimpedance) and peritoneal permeability at early start of peritoneal dialysis. Thus, we investigated early cinetic of peritoneal permeability at different time point during the first year of peritoneal dialysis and we analyzed the demographical and biological factors associated with HPP and overhydratation during this period. This study is a prospective, multicentric cohort study. Fourty patients recruited in a two years' period in five centers of nephrology will be included. Hydratation status will be determined with Fluid Overload measurement by bioimpedance technic thanks to BCM system (Fresenius Medical Care®). Peritoneal permeability will be determined by modified Peritoneal Equilibration Test with complete drainage at sixty minutes. Datas will prospectively be collected, including: weight, blood pressure, diuretic posology, diuresis, PD modality, dialysate prescribed.

Lighthouse, in cooperation with the University Heidelberg Public Health Institute and the University Köln (Cologne) would like to set up a cohort to study baseline characteristics and long-term clinical outcomes of patients using Tenofovir based Antiretroviral Therapy at the Lighthouse. As of March 2014, patients above 18 years and giving informed consent coming to the Lighthouse to newly initiate ART will be approached to enroll in the cohort. The results will be disseminated both nationally at the Ministry of Health Technical Working Group (TWG), at the annual Research Dissemination and Best Practices conferences of the College of Medicine and National AIDS Commission as well as internationally. The results will also be written up for publication in appropriate peer-reviewed journals.

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.

This study evaluate the frequency and type of eye problem among Type 2 Diabetics with renal impairment and effect of renal impairment and haemodialysis on diabetic retinopathy

Methods of diagnostic and treatment of hormonal disorders in patients with chronic kidney disease (CKD) will be developed and implemented in real clinical practice. As a result of the project, new scientific data will be obtained on the relationship of hyperprolactinemia and impaired functioning of the pituitary-gonadal axis, changes in functioning of the renin-angiotensin-aldosterone system will be revealed, and the characteristics of the thyroid and parathyroid status in patients with CKD will be determined, including receiving renal replacement therapy (RRT) and after kidney transplantation, which will improve the efficiency of diagnosis and treatment of hormonal disorders in the early stages of the disease, reduce the direct financial costs of the diagnostic and treatment process primarily due to the optimization of hormonal studies and treatment of the revealed disorders, as well as will prevent the progression of CKD and the severity of the condition of this category of patients due to the development of hormonal dysfunctions.
