Active clinical trials for "Kidney Diseases"

Autosomal dominant polycystic kidney disease (ADPKD) is an inherited disease. We plan DNA analysis using the next generation sequencer (NGS) and examine the relationship between mutational types and clinical phenotypes. The accuracy of DNA analysis with NGS is tested by Sanger's method. The kidney and life survival curves will be compared between PKD1, PKD2 and non-ADPKD family members.

The lifestyle consulting program through one year follow-up could effective increase the scores of health responsibility and nutrition according to the past three-year study. Behavior change is a dynamic and complex process. Using a long-term follow up approach will be able to understand the trajectory of behavior change. The purpose of this study is to explore life experience and lifestyle intervention program for patients with chronic kidney disease using mixed methods with a longitudinal approach. The first year of this study will include a qualitative study with in depth interview of the subjects who attend previous study in the research team and have the scores of health promoting lifestyle among the highest 27% and lowest 27%. The life experience will be explored. The quantitative study will be an experimental design. Qualified subjects will be randomly assigned to intervention or control group. The intervention protocol is based on trans-theoretical model. Each subject will be followed every six months. The second and third year of studies will continue to use the qualitative and quantitative approach to understand the life experience and meaning among patients with chronic kidney diseases. The trajectory of life experience and life style changes will be explored. The method may strengthen the effectiveness of lifestyle program and may provide comprehensive understanding of the trajectory of behavior changes among patient with chronic kidney disease.

Diabetes mellitus (DM) is a metabolic disorder commonly encountered by the healthcare professionals. Diabetic nephropathy is one of its complications, which is becoming the most common cause of end-stage renal failure in Hong Kong. As of March 31, 2000, a total of 1026 patients with diabetes were on renal replacement therapy and the number is steadily increasing. According to ADA guidelines, screening for diabetic nephropathy should be performed on an annual basis to assess urine albumin excretion rate. Serum creatinine should also be measured in all diabetic patients regardless of the degree of urine albumin excretion rate. Timed urinary collection can be a cumbersome procedure for patients and a simpler and fast test that maintains reasonable sensitivity is called for. A tool that is non-invasive and able to identify patients with early nephropathy changes would be valuable. The skin has been found to have the potential to provide an important non-invasive route for diagnostic monitoring of human subjects for a wide range of applications. eZscan® technology is a patented active electrophysiological technology which uses low level DC-inducing reverse iontophoresis, together with chronoamperometry, to evaluate the behaviour of the tissues in specific locations of the body. This non invasive test is a potential tool for the screening for diabetic nephropathy. The aim of this study is to compare eZscan with the standard methods of screening for diabetic nephropathy in patients with type 2 diabetes mellitus.

Background: Contrast-induced nephropathy (CIN) is a serious clinical problem associated with increased morbidity and mortality, particularly in patients with chronic renal insufficiency. Although some agents including hydration with saline are being prescribed to prevent renal deterioration in these high risk patients, their efficacy is not clear defined and debatable. Therefore additional prophylactic pretreatments are needed. Methods/Design: Present study aims to investigate differences in occurrence of CIN after sarpogrelate premedication in patients with chronic kidney disease (CKD). 268 participants, aged 20-85 years with a clinical diagnosis of CKD will be recruited. They will be randomly allocated to one of two conditions: (i) a routine treatment without sarpogrelate group (ii) routine treatment with sarpogrelate (a fixed-flexible dose of 300 mg/day). The primary outcome is the occurrence of CIN during 4 weeks after receiving contrast agent. Discussion: As of May 2010, there were no registered trials evaluating the therapeutic potentials of sarpogrelate in preventing for CIN. If sarpogrelate decreases the worsening of renal function and occurrence of CIN, it will provide a safe, easy and inexpensive treatment option.

A pilot study for PK/PD parameter of colchicine in Chronic kidney disease patient.

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.

Contrast-induced nephropathy (CIN) is a well-recognized complication of radiographic contrast administration and is associated with increased short- and long-term mortality. Previous strategies including forced diuresis with diuretics or mannitol, intravenous administration of fenoldopam or dobutamine, and postprocedure hemodialysis to prevent CIN have been largely unsuccessful. In addition, the use of N-acetylcysteine to prevent CIN has yielded conflicting outcomes. A review of a large insurance database and retrospective study have shown that statins therapy is associated with a lower incidence of CIN after percutaneous coronary intervention. The preventive effect of statins on CIN may be attributed to direct pleiotropic effects on the vascular wall such as improvement of endothelial dysfunction, anti-inflammatory or anti-oxidative effect. However, recent randomized trial could not demonstrate the preventive effect of statin on CIN in patients with chronic kidney disease. Thus, we will investigate the preventive effect of pitavastatin on CIN in patient with renal dysfunction undergoing coronary angiography or intervention.

Longitudinal cohort of patients with chronic kidney disease followed in 3 kidney centers in Ontario. The goal is to determine whether and how rates of renal disease progression are affected by inflammatory markers, FGF23 levels, and genetic polymorphisms

This study is being implemented for 3 aims. The first has been to conduct a systematic literatures review on CKD intervention models and their effectiveness. Findings have been adopted in our intervention program. The second purpose is to establish a practical management model or an intervention model for CKD patients and high risk population with the 18-month of follow-up.In the third year, we will use social perspective point to evaluate the costs and the benefits of intervention.

The purpose of the study is to monitor initiated Diafer® therapy administered according to hospital practice and the product labeling in routine clinical practice in haemodialysis patients with Chronic Kidney Disease.
